In 2011, three top US government scientists penned an opinion piece in The Washington Post arguing why research modifying highly pathogenic avian influenza (H5N1) was a worthy undertaking. At the time, the National Institutes of Health (NIH) was facing blowback over having funded experiments that modified the virus to be transmissible among ferrets. The scientists argued that eliciting potentially dangerous mutations in the virus was necessary to protect humanity, should those mutations evolve naturally.

We cannot predict whether or not something will arise naturally, nor when or where it might appear. Given these uncertainties, important information and insights can come from generating a potentially dangerous virus in the laboratory, wrote Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases, Francis Collins, the head of NIH, and Gary Nabel, then a top official at Faucis institute.

Amid the controversy generated by this influenza research, the US government implemented a pause on federal funding in 2014 for selected research reasonably anticipated to increase transmissibility or pathogenicity of influenza, SARS, and MERS viruses. These were experiments that fell within a subset of scientific study called gain-of-function research. In 2017, the government lifted the pause and put in place a requirement that the US Department of Health and Human Services conduct a risk-benefit assessment on research that could confer these attributes to potential pandemic pathogens.

The federal government continues to fund such experimentation, but, as scientists, media, and online sleuths have delved into the origins of COVID-19, they have revealed weaknesses in past and current government oversight of projects modifying viruses. The revelations have underscored the degree to which gain-of-function research in the name of predicting pandemics is an idea that doesnt seem to fade.

US-funded coronavirus bioengineering. In 2018, EcoHealth Alliance, a US-based nonprofit research organization, submitted a grant proposal to the Defense Advanced Research Projects Agency (DARPA) called DEFUSE: Defusing the Threat of Bat-borne Coronaviruses asking for over $14 million for a three-and-a-half year project to, as the name suggests, prevent a bat coronavirus from spilling over into people and seeding an outbreak. The team would study viral evolution and spillover risk[s] of SARS-related bat coronaviruses by collecting viruses from caves in Yunnan, China and doing experiments that included testing hybrid, lab-created bat coronaviruses on mice engineered to have human receptors.

One eye popping segment in the 2018 EcoHealth proposal to DARPA dealt with finding so-called furin cleavage sites. In SARS-CoV-2, the virus that causes COVID-19, a furin cleavage site allows its spike protein to be cut by the furin enzyme present in human airway tissues, making the virus better able to infect cells than others without the feature. The furin cleavage site represents a crucial difference between the COVID-19 virus and its relatives, including SARS-CoV, the virus responsible for the 2003 outbreak of that respiratory disease.

The process by which viruses hijack the cellular machinery of their hosts to reproduce themselves is sloppy, and the viruses that a cell produces arent always identical to the ones that infected the cell to begin with. This sloppiness helps the virus to evolve and adapt to new hostssuch as us. The furin cleavage site in SARS-CoV-2 could have evolved in this way.

Some proponents of the idea that the pandemic began with a lab accident in Wuhan, however, wonder whether the furin cleavage sites presence in the COVID-19 virus is simply a mark of natural viral evolutionan artifact of sloppy viral reproductionor rather is something else entirely: a sign of human bioengineering.

DARPA did not approve EcoHealths 2018 proposal, and its unknown whether the project received other funding. But the EcoHealth proposal, like another of the organizations collaborations with the Wuhan Institute of Virology that did get government funding, show the enduring interest scientists have in modifying viruses in the name of predicting pandemic pathogens. (NIH officials have denied that EcoHealths NIH-funded research is gain of function research, although NIH documents show that the organization failed to adhere to terms related to enhanced viral growth in its hybrid bat coronavirus studies. There is significant debate on what the definition of a dangerous gain-of-function experiment is.)

Predicting pandemics through gain-of-function research. An overarching goal of EcoHealths workas documented in the DARPA proposal and in other projectswas to learn which viruses were poised to spill over, in other words, to predict pandemics. Predicting how and when the next pandemic could arise is important, but tampering with viruses to do so is the wrong way to go about it. Predicting pandemics isnt like predicting the weather.

Weather prediction is a purely observational exercise. We have satellites and other tools to track weather to predict hurricanes. The forecast process begins with observations. Scientists use this data to develop hurricane forecast models. Geophysical fluid dynamics are well understood, based on the laws of physics (i.e. density, flow velocity, pressure, and temperature) enabling scientists to develop atmospheric and climate models.

Scientists do not experiment on clouds to see if they can cause hurricanes.

In 2004, the National Academy of Sciences published its seminal report, Biotechnology Research in an Age of Terrorism. It listed seven experiments of concern that should not be done.

Bioengineering SARS-related coronaviruses in ways that could increase efficient infection of human cells and that increase viral load, pathogenicity, and lethality in mice genetically engineered to have respiratory cells with human features, i.e., humanized mice, as NIH documents show was done by EcoHealth Alliance and its Wuhan partners, would conceivably implicate points 3, 4, and 5 of the 2004 report. Whether the Wuhan experimentation was gain of function is a matter of debate, but some scientists disagree with NIHs assessment that it wasnt.

Ideally, Congress should hold a hearing to debate what kind of research should not be done and do more to investigate the origins of the pandemic. Certainly, there have been calls to do so.

There are other less risky ways of preventing pandemics than conducting gain-of-function research on pathogens. Many pathogens capable of causing human outbreaks originate in animals, and surveillance of wild and domestic animals for signs of illness makes sense. This is the One Health approach. With One Health, the goal is to prevent the spread of deadly zoonotic microbes into humans through improved communication and collaboration between human and veterinary medicine.

Preventing pandemics through rapid identification and response is an important goal; the One Health approach that emphasizes animal and human health and disease surveillance is the key to doing this, not risky gain-of-function research.

Jurassic World Evolution 2 review: When dinosaurs ruled the Earth – Shacknews

Jurassic World Evolution launched in the same year as the second film in the rebooted blockbuster series and gave fans the opportunity to live out their own dreams of opening a theme park full of dinosaurs. Three years later, the games sequel looks to double down on that promise, putting even more tools and options in the hands of players. Jurassic World Evolution 2 cleverly expands upon what was built in the first game, delivering the definitive Jurassic experience.

In Jurassic World 2, players can build their own dinosaur theme park using enclosures, facilities, and scientists. Theres a lot of systems at play, and the core game is a balancing act of making sure your dinosaurs are taken care of and happy, guests are happy, and that your park is turning a profit.

Players are introduced to the games mechanics in Campaign mode. Set after the events of Jurassic World: Fallen Kingdom, players will work with the DFW (Department of Fish and Wildlife) to control, conserve, and contain the wild dinosaurs that now roam the planet. Each chapter of the Campaign has players in different locations looking to build a functioning park or conservation area. From Arizona, to Washington, California and more, it was neat to have a diverse offering of environments, rather than the jungle settings that we always see in Jurassic Park adaptations.

The Campaign is brief, easily beatable in a couple of sittings. That said, its a satisfying experience that eases players into the different systems that they will have to juggle. As someone who can sometimes feel overwhelmed in management sims, I felt equipped to deal with just about everything Jurassic World Evolution 2 threw at me. It was also cool having Jeff Goldblum and Bryce Dallas Howard reprise their roles from the films and serve as mentors throughout the story.

When building a successful park, theres a lot that players will need to take into account. Enclosures need to be built for every dinosaur, as to keep both the guests and creatures safe. Each species of dinosaur has its own unique needs that inform the player how to design their enclosure. For example, Velociraptors desire a lot of open space, as well as live prey to hunt down. The Carnotaurus wanted to be in a sandy environment, so I had to whip out the brush tool and make their enclosure look like a desert.

Theres over 75 species of dinosaurs featured in Jurassic World Evolution 2, and each one feels distinct from the next. This game also adds flying and marine creatures, adding more variety to what players can do with their parks.

Players can get a full read of everything they need to know about a dinosaur by pulling up its information page. This tells the player a dinosaurs comfort level, health status, genetic makeup, and even a stats page that will show you everything from a dinos age and dollar value, to how many creatures its killed and how many times it broke out of its enclosure. The amount of information the game gives makes each creature feel unique. I found myself growing attachments to some of the dinosaurs I had long term and I was genuinely saddened when they died or became unwell.

One of my favorite things to do in Jurassic World Evolution 2 was to hop into a ranger truck, and then drive around an enclosure in first-person. Seeing dinosaurs like the T-Rex and Brontosaurus up close, scaled to actual size, was incredible.

In addition to having cool dinosaurs and making sure theyre taken care of, players still need to manage a theme park. Buildings like viewing centers, restaurants, gift shops, and hotels make the guests happy, increasing profits. On the business side of things, operation facilities like the Control Center, Medical Facility, and Response Facility are integral to maintaining your park. Scientists can be hired to carry out tasks such as healing dinosaurs, going on expeditions to acquire new creatures, and conducting research in order to unlock new structures and perks. Each scientist has their own advantages and disadvantages, as well as a salary to match.

Theres a deep level of strategy and management just on the business side of things. Having to properly budget my income so that I could afford scientists, managing their time so that they didnt become fatigued or disgruntled. Fostering an environment that made my guests feel safe and excited to spend money was a good deal of fun on its own.

My only frustration with Jurassic World 2 comes in the repetitiveness of its gameplay loop, particularly early on in a playthrough. From random weather conditions, to illnesses and dinosaurs deciding to break fences and escape their enclosure, it can feel like youre in a constant state of panic, frequently pausing time to play an endless game of whack-a-mole. As more perks are unlocked, this becomes a bit less stressful.

One of the most fascinating mechanics in Jurassic World Evolution 2 is its bioengineering system, which lets players create their own dinosaurs just as Dr. Henry Wu and his team of scientists did in the films. Using a Hatchery, players can combine genomes from different species of reptiles in order to create a dinosaur thats wholly unique. These dinosaurs can have special behavioral traits, colors, and patterns. I spent a considerable amount of time just screwing around in Sandbox mode seeing what wild abominations I could come up with.

Chaos Theory is a new mode in Jurassic World Evolution 2 and puts players in scenarios from the Jurassic Park/World series, giving them a chance to rewrite history. These what if scenarios include realizing John Hammonds dream of building a Jurassic Park in San Diego, or maintaining Jurassic World on Isla Nublar without the incident in 2015. These missions offered a fresh challenge and are an excellent way to revisit major turning points in the franchise.

Jurassic World Evolution 2 is endless fun for a fan of the blockbuster franchise. A large library of species to unlock and study, bioengineering, and the ability to revisit iconic moments from the movies makes it an easy recommendation for anyone looking for their fix of Jurassic content. Even as a park manager, the game is quite satisfying, aside from some light frustrations here or there.

This review is based on a digital download code provided by the publisher. Jurassic World Evolution 2 is available now for $59.99 USD on PC, Xbox One, Xbox Series X, PS4, PS5, and PC.

New imaging technology could buy time for pancreatic cancer patients – University of Rochester

November 18, 2021

The insidiousness of pancreatic cancer is how it develops without showing any definitive symptoms. In most cases, by the time it is diagnosed, it is beyond cure.

And yet, for 10 to 20 percent of patients, pancreatic cancer is caught soon enough, before it has metastasized. This provides surgeons a narrow window of time to try to treat the tumors, shrinking them enough to safely remove them.

University of Rochester engineers, imaging scientists, surgeons, and immunologists are working together on a novel imaging technology to help surgeons make the most of that narrow time frame before the cancer spreads.

Led by Marvin Doyley, professor and chair of electrical and computer engineering at the Hajim School of Engineering and Applied Sciences, the collaborators have received a $2.4 million grant from the National Institute of Biomedical Imaging and Bioengineering to look at pancreatic cancer tumors in a different waymeasuring not just their size, but also their elasticity and ability to be perfused, or permeated, with blood and other fluids.

Standard imaging modalities such as MRI (magnetic resonance imaging) or CT (computed tomography) have been used to see if a tumor is shrinking, Doyley says. But there is a lot of data that suggests just looking at size reduction by itself is not necessarily the best marker to judge whether patients are responding to therapy. Were basically trying to fix that.

The ultimate goal is to develop an endoscopic device that surgeons could use to look inside the body in order to determine whether a patient is responding to treatment and, if so, when they are ready to undergo tumor removal.

The first step is to demonstrate whether increases in tumor elasticity and perfusion are indeed valid biomarkers to more quickly determine that a tumor is responding to treatment in ways that will help ensure a successful surgical outcome. And if not, to switch to a different treatment.

Pancreatic cancer tumors typically have a stiff barrier around them, which can pinch off the ability of blood vessels to perfuse the tumor with chemotherapy drugs designed to shrink the tumor, Doyley explains.

To address the specific challenges of pancreatic cancer tumors, the researchers will use a combination of two imaging modalities:

This will enable the team to measure whether tumor elasticity and perfusion change in mice models as they respond to various tumor-shrinking therapiesand if so, to fine tune the ability of the imaging technology to detect the changes.

These images from magnetic resonance imaging and magnetic resonance elastography are from a patient with pancreatic cancer. Arrows point to tumors. (Images courtesy of the Doyley lab)

Then, the researchers will use analogous forms of MRI imaging to see how the same properties change in actual patients undergoing treatment.

Once a patient is initially diagnosed with pancreatic cancer, well track how those biomarkers vary as they have their different treatments, Doyley says. We cant do a full clinical trial, but we can retrospectively see, in patients who have responded, if there is a corresponding change in the biomarkers we are looking at.

And if there is indeed a link between the biomarkers and treatments, continues Doyley, we will apply for a bigger grant to create an endoscopic device and do a bigger study with more patients.

Collaborators include Brian Pogue, recently appointed chair of the Department of Medical Physics at the University of WisconsinMadison, and, at Rochester, David Lenihan, professor and chair of surgery; Scott Gerber, associate professor of surgery and of microbiology and immunology; Aram Hezel, associate professor of hematology/oncology; Tanzy Love, associate professor of biostatistics; Jonathan Kallas, assistant professor of imaging sciences, and David Dombroski, associate professor of imaging sciences.

Right off the bats – Newswise

Newswise Among the many devastating impacts of Alzheimers disease and other types of dementia is the risk that patients will wander and become lost. Indeed, according to the Alzheimers Association, six in 10 people with the disease will wander at least once over the course of their illness and many do so repeatedly.

For researchers who study and treat people with neurodegenerative disorders, understanding the human neural circuitry that leads to such behavior is among the highest-priority goals. But to better study these and other neurological conditions, the work needs to begin with effective, accessible animal models.

Thats where researchers at the NeuroBat lab led by Michael Yartsev, assistant professor of bioengineering and of neurobiology come in. Their studies of the neural circuitry of navigation in Egyptian fruit bats are yielding insights that might one day help explain and prevent dangerous situations for humans.

Egyptian fruit bats are one of the most superior navigators that exist on our planet, Yartsev says. He describes how these diminutive, highly social creatures in the wild will travel tens of kilometers, even through dark and stormy nights, seldom if ever getting lost in their search for food. The bats complex travel through 3D space, he says, could shed light on the complexity of human behavior in navigating from place to place.

But understanding the neuronal processes at the root of behavior in appropriate animal models goes well beyond studies of navigation. We have a huge number of questions that we want to understand about the brain, Yartsev says. And one of his goals as a neuroscientist is to advocate for an expansion of the diversity of animal models researchers have available for their work.

In the current landscape of neuroscience research, Yartsev says, 75% or more of the work focuses on a handful of standard organisms, such as rats and mice. The reasons often come down to accessibility of tools and ease of maintenance in laboratory environments. But this overwhelming convergence is not without cost, as it limits the type of questions asked, the discoveries made and the degree to which scientific findings can be generalized beyond those species.

With bats, Yartsev says, their ability to fly, complex social behaviors, patterns of vocalization, long lives and more set them apart as animal models for studying a specific set of basic research problems in neuroscience such as how the brain processes skills like navigation, sociality and language.

Yartsevs first encounter with bats as a subject for neuroscience took place some 15 years ago during his Ph.D. studies at the Weizmann Institute of Science in Israel. Yartsev says it was a risky move, then, to pursue a Ph.D. in neuroscience by studying a non-traditional animal. But this work helped establish bats as an important model system for a variety of new research topics.

As befits Yartsevs biomedical engineering background, the work has included the opportunity to develop new research tools for neuroscience for example, the first wireless electrophysiology system for recording and studying a bats brain activity during flight.

This was the first single-cell neural recording from a freely flying animal, Yartsev says, referring to experimental work behind a 2013 Science paper on navigation-related bat neural activity. Bats obviously cannot fly around freely with a cable attached, so we had to develop the tools needed to do this work we still do, he adds, citing, as another example, a piezoelectric device for recording vocalizations that is lightweight enough for the bats to wear as a necklace while communicating with one another.

In 2015, Yartsev brought his pioneering research with Egyptian fruit bats to UC Berkeley, where he has established his own group, the NeuroBat Lab. Studying the neural circuitry of these diminutive creatures, the group continues to build and publish a rich trove of basic research data and neuroscience insight with more to come.

In a continuation of his research work on navigation using bats, the NeuroBat Lab has recently focused on neural mechanisms that could underlie goal-directed navigation, which Alzheimer patients often struggle with. To carry out the study, the Yartsev team used a specialized facility they created called the fully automated flight room. It is a human-free space used to obtain detailed, quantitative understanding of bat navigation and flight behavior by recording activity in relevant neural circuits.

Bioengineering graduate student Madeleine Snyder, one of Yartsevs team members who also studies the neural mechanisms of navigation in bats, says bats make a good research subject because theyre both highly social and highly navigationally adept, and thats very similar to humans in many ways. They will go kilometers and kilometers to forage in a specific tree and then come home together.

She describes the flight room as about the size of a large living room that is outfitted with cameras and other recording devices. Researchers can situate perches for the bats at various places in the room. The perches might be outfitted with beam breakers that, when triggered by a bat alighting on the perch, will trigger some action like the introduction of food. Lights can be programmed to turn on and off, sounds can be introduced and researchers can simply step back, watch and record how the bats interact with their environment.

In comparison to studies with other animal models, she says, with bats in the human-free flight room, were not constraining the animal but just letting them do what they want to do and seeing what happens.

As with many animal-model studies, Yartsev says, subtracting humans from the study environment can heighten fidelity of results. Thats because the presence of human investigators may introduce experimental biases, reduce reproducibility of the experiment, prevent the animals from engaging freely in self-paced navigational behavior and limit the complexity of tasks that could be utilized to study neural circuits.

For the navigation study, the team looked at the activity of place cells, specialized cells in the brain that act as a sort of internal global positioning system. Studies of place cells in rats had indicated that the cells primarily encode the animals location at the time the cell is firing.

What we are showing in this paper is that if you align all the place cells that you are recording as they are firing in the hippocampus, there is a continuum of space and time, Yartsev says, referring to their paperpublished in Scienceearlier this year. The cells are representing where the animal has been, where it will be a half a second into the future, a second into the future and so on.

One of the hallmarks of Alzheimers disease, Yartsev notes, is that people get lost all the time, even in their own neighborhoods. Understanding how the brain represents the environment, how a person knows the route to take to get from one place to another remains unknown, he says. The NeuroBat Lab study suggests that the reason a person might get lost is that their brain somehow loses that continuum of space and time the ability to hold and follow a planned trajectory.

He says the data from their fast-moving bat animal model reveals dynamics of neuronal activity that would be difficult to observe so cleanly by only studying, for example, a slower-moving rodent in a 2D maze.

We can sometimes make very significant progress with just one experiment with bats, no matter that it can at times be very difficult, Yartsev says. Thats because the animals can be a highly relevant model system for a specific scientific question that could also be important for humans. For example, bats are specialized for communication at the group level. They have developed behavioral capacities for group living and the underlying neural circuits that serve those capacities.

In another recent study from the lab, the team became the first to observe synchronized brain activity in a nonhuman species engaging in natural social interactions like grooming, fighting or sniffing each other.

For the study,published in Cell,Yartsev and postdoctoral fellow Wujie Zhang used simultaneous wireless neural recording devices to measure brain activity while multiple bats freely interacted. The specialized recording devices allowed them to capture what modalities like functional MRI and EEG cannot the full scope of neural activity from brain oscillations to the firing of individual neurons, all at the same time.

The researchers found surprisingly strong correlations between the bats brains. That is, as they engaged with one another in social behaviors in the same environment, their brain wave and neuronal electrical activity began to look the same in each bat, even when the bats performed very different actions. The correlations were present whenever the bats shared a social environment and increased before and during their social interactions, Yartsev says.

Their detailed analysis of social interactions allowed them to rule out other possible explanations for the synced-up brain activity, such as that bats were simply reacting to the same environment or engaging in the same activity. For example, bats placed in identical but separate chambers and that were both busy grooming did not show the same synchronization.

This study is really laying the groundwork for studying inter-brain correlation in animals, Zhang says. We didnt know if this is something thats only observed in humans. If we have the same phenomenon in animals, then theres a lot more experimental techniques we can use to really understand the mechanisms of this phenomenon, including its function.

This is a very core phenomenon that, for two decades, people have been excited about in humans, Yartsev says. Now that weve observed it in an animal model, it opens the door to very detailed research of it. Importantly, this phenomenon also relates to how humans socialize with one another in social groups and is impacted during diseases such as autism and other neurological disorders. Understanding the neural mechanisms behind it and how it mediates natural group social behavior could lead to future therapeutics in humans.

And this is exactly where we are going with this, Yartsev says. In another paper,published in Sciencethis fall, the lab studied social communication among groups of bats for the first time. Led by graduate student Maimon Rose and postdoctoral fellow Boaz Styr, the researchers discovered a rich repertoire of neural signals that represent key components in group communication, findings that could also have significant implications for understanding aspects of human mental health.

Another future area of research interest, Yartsev says, is language the crown jewel of humanity. Humans are the only mammals capable of learning and using language, but they are joined by bats, elephants and cetaceans (whales, dolphins) out of some 5,400 species of mammals in the ability to learn new sounds. This process, also known as vocal learning, is the basis for language learning.

First of all, just understanding that fact about learning language is really important, he says. How does our brain allow us to learn a language? It becomes even more important when we think that about 10 percent of the people in the world suffer from language disorders. And this affects them dramatically. These disorders relate to autism, dyslexia and a whole variety of problems related to brain functioning.

Unfortunately, in the world of neuroscience today, Yartsev says, we still do not understand the detailed neurobiological mechanisms that allow us to learn a language.

And beyond biology and human health, the research into complex neurobiological processes in bats might also power new technology development, Yartsev says. For example, insights from the bats might aid development of new machine learning algorithms and sensing technologies critical to the development of fully self-driving cars. Such autonomous vehicles must be able to safely maneuver roadways by sensing and reacting to other moving vehicles, random obstacles and constantly changing environmental conditions. For some questions, the bats provide us very unique advantages that you simply cant find in other animal model system and these are the questions we focus on, Yartsev says.

2D Perovskite Nanosheet-Based Drug-Delivery Platform for Cancer Therapy – AZoM

The latest research in the Chemical Engineering Journal focuses on a sophisticated two-dimensional (2D) photonic drug-delivery technology based on PEGylated WO2.9 nanosheets (a substoichiometric version of WO3) (NSs).

Study:Oxygen-deficient tungsten oxide perovskite nanosheets-based photonic nanomedicine for cancer theranostics.Image Credit: Love Employee/Shutterstock.com

Photothermal therapy (PTT), a non-invasive technique of tumor treatment that employs photothermal agents (PTAs) to create local hyperthermia using near-infrared (NIR) laser light, has been extensively researched and has garnered considerable focus.

Perovskite nanosheets offer several appealing traits as 2D nanomaterials, including surface area features, mechanical flexibility, strong light-matter interaction, minimal trap-state density, and higher adsorption efficacy. Some perovskite nanosheets exhibit high photoluminescence.

However, because of the restricted tissue depth of penetration of the typical NIR-I bio-window (650950 nm), most PTT mediated by NIR-I is still insufficient for the effective treatment of big or severe tumors, contributing to an elevated remnant and recurrence rate.

In comparison, the NIR-II (10001700 nm) bio-window had a higher maximum permitted exposure (MPR), decreased photon scattering, increased penetration depth, and reduced tissue background, allowing NIR-II PTT to significantly enhance tumor treatment efficiency. Unfortunately, in comparison to the PTA active in the NIR-I region, the advancement of NIR-II materials is still behind.

The materials used by the researchers for the experiment included Sodium tungstate monohydrate (Na2WO4H2O), nitric acid (HNO3), chloroform (CHCl3) sodium borohydride (NaHB4), doxorubicin hydrochloride (DOX), calcein-AM, Propidium Iodide (PI), 4,6-diamidino-2- phenylindole (DAPI), and CCK-8.

Phosphate-buffered saline (PBS) (pH 7.4), cell culture medium, fetal bovine serum (FBS), penicillin-streptomycin, and trypsin-EDTA were also utilized during the research study.

Transmission electron microscopy, scanning electron microscopy, and atomic force microscopy was utilized for the research study.

First, 200 mg of Na2WO4H2O were scattered in 300 mL of HNO3 solution (5 M). The combined mixture was then swirled for three days at room temperature (RT) for bulk production of WO3H2O. Two rectangle porcelain crucibles with a volume of 5.0 cm 2.0 cm 1.5 cm were used. Firstly, 10 mg of WO3H2O NSs was placed in one of them, NaBH4 (5 mg) was placed in the other one. Two porcelain crucibles were then placed in a tubular furnace, and the porcelain crucibles containing WO3H2O NSs were held on top of the other with a rotation angle of 20.

To make PEG-coated WO2.9 NSs, WO2.9 NSs (10 mg) were combined with 25 mg DSPE-PEG dissolved in CHCl3 solution in 30 mL CHCl3 solution. The CHCl3 solution was removed using vacuum rotary evaporation after 30 minutes of ultrasonic treatment.

Different concentrations of DOX were dissolved in PBS solution (pH 7.4, 10 mM) and further mixed with [emailprotected]2.9 NSs. The final concentration of DOX was 0.2, 0.4, 0.6, 0.8 and 1 mg mL 1, respectively.

In the DMEM medium, 4 T1 cells, HUVEC cells, NCM-460 cells, and Hela cells were incubated. FBS (10%) and streptomycin/penicillin (1%) supplements were administered to all of the DMEM media for the generation of cell cultures.

The latest study showed that WO3H2O NS exhibited the typical Raman-active peaks at 120, 267, 326, 684, 810, and 960 cm 1. The PEGylated WO2.9 NS ([emailprotected]2.9 NS) still retained good dispersity and stability in the PBS and medium even after 24 h incubation, indicating that the dispersity and stability are significantly bet.

When the quantity of [emailprotected]2.9 NSs was 200 mg mL 1, the greatest temperature generated by 2.0 Wcm2 NIR-I irradiation was only 32.2 C. Under 808 nm and 1064 nm irradiation, the photothermal conversion efficiency of [emailprotected]2.9 NSs is determined to be 18.7 percent and 36.2 percent, respectively. These findings imply [emailprotected] NSs have a high potential for use as a photothermal agent for PTT against tumors in the NIR-II window.

The medication loading capacity of [emailprotected] NSs was then examined using a UVvis absorption spectrum. The concentration of DOX loaded onto [emailprotected] increased with the addition of the concentration of DOX, and the maximum drug load efficiency was approximately 102 percent at our studied parameters, which is significantly higher than most nanoparticle-based delivery platforms with drug-loading capacities of 10%30%.

In all cases, four T1 cells were co-cultured. There was no evident cytotoxicity in the groups that simply received NIR-II or [emailprotected]2.9 therapy. Hence, both nontoxicity and biocompatibility were confirmed.

Keeping in view the incredible findings, the WO2.9-based nanoplatform may open the way for a novel method to use more effective perovskite theragnostic nanomedicines for the cure of diverse solid cancers.

In short, 2D perovskite nanosheet drug delivery has been proved to be not only biocompatible but also quite effective for cancer treatment, revolutionizing biomedical applications of such materials and improving the health care treatment quality for people.

Nanofabrication: Techniques and Industrial Applications – AZoNano

As a bridge between fundamental research and the industrial application of nanotechnology, nanofabrication methods are essential in creating novel nanoscale structures, devices, and materials with unique properties. This article aims to overview the existing and emerging techniques for scalable, reliable, and cost-effective manufacturing at the nanoscale.

Nanotechnology enables the understanding and control of matter at length scales between one and a few hundred nanometers, where the quantum effects dominate the properties of the materials.

The use of nanoscale materials has started quite early in human history and dramatically increased in the last 100 years. The study of small nanoparticles was pioneered by Richard Zsigmondy, an Austro-Hungarian colloid chemist, who was awarded the 1925 Nobel Prize in Chemistry. He used the term 'nanomatter' when characterizing particles such as gold colloids by using a microscope.

In 1959, Richard Feynman introduced the idea of manipulating matter at the atomic level. The future Nobel Laureate (he was awarded the 1965 Nobel Prize in Physics) presented a lecture at a meeting of the American Physical Society, where he speculated about miniaturized electronic components, atom-by-atom manufacturing, and novel optoelectronic and photonic technologies.

Feynman, who foresaw many aspects of modern nanoscience, together with K. Eric Drexler, who in 1986 hypothesized on how molecules and atoms can be manipulated and assembled into complex nanostructures, are considered the fathers of modern nanotechnology.

Since then, nanotechnology has become the foundation for many remarkable applications leading to exponential growth in almost every industrial sector. In the last three decades, rapid developments in physics, chemistry, engineering, and material science manipulated individual molecules and atoms' reality, thus enabling various manufacturing processes at the nanoscale, usually referred to as nanofabrication.

Nanofabrication can be defined as a process of assembling one-, two- or three-dimensional structures at the scale of 1-100 nm with a high degree of functionality and structural complexity. There are different methods for creating functional nanostructures that can be divided into top-down and bottom-up approaches.

In the top-down approach, the starting material is reshaped into the desired smaller structures by using physical or chemical processes, such as electron or ion beam milling, laser ablation, and reactive ion etching, that remove excess material until the final structure is obtained.

In contrast, bottom-up nanofabrication relies on the formation of nanostructures from individual atoms and molecules. Processes include chemical and physical vapor deposition (CVD and PVD), self-assembly, and epitaxial growth.

The majority of the industrial nanofabrication processes employ a combination of the two approaches and can be loosely divided into three major sub-processes: thin film deposition, lithographic patterning, and chemical or physical etching.

Thin films are layers of polymers, metals, semiconductors, or other functional materials with nanometer-level thickness. They are fabricated using a variety of deposition processes, including CVD, PVD, atomic layer deposition, and molecular beam epitaxy.

The lithography process involves patterning the as-deposited thin films to create integrated circuits or nanoelectromechanical systems. The latest generation of optical nanolithographic systems employs X-ray, extreme UV, or charged particles beams to create nanoscale patterns with a spatial resolution of less than 10 nm.

The pattern transfer is finalized by an etching process that selectively removes the unnecessary parts of the thin film

Such a combination of top-down and bottom-up methods, for example, underpins the tremendous advances in microelectronics and over the last 30 years.

With the development of the UV and extreme UV nanofabrication processes that permit the creation of structures smaller than 10 nm, the semiconductor industry has been able to continuously increase the integration density of the electronic circuits.

The technological developments behind the large-scale production of advanced integrated circuits, in turn, enabled the transfer of cost-effective nanofabrication techniques to the fields of telecommunications, optoelectronics, and photonics.

Nanomanufacturing can also help create materials with novel properties. With the discovery of nanomaterials like fullerenes, carbon nanotubes, graphene, nanodots, and metallic nanoparticles, a lot of academic and industrial research and development efforts were directed at incorporating such nanomaterials in the manufacturing of advanced construction materials, consumer goods, textiles, and healthcare products.

Surface nanopatterning (to create superhydrophobic surfaces) together with metallic nanoparticle coatings are used in antimicrobial applications. Building materials benefit from nanostructured coatings that enable self-cleaning and antifouling functionality.

Automotive and aerospace industries utilize metal oxide nanoparticles for temperature and corrosion protection, and carbon nanotube-based nanocomposite materials as high-strength structural materials.

The so-called 'soft nanotechnology', based on the self-assembly of large organic molecules (polymers and proteins), is an emerging field with rapidly expanding industrial applications.

The concept of using cheap and sustainable biobased resources to fabricate organic nanostructures is particularly attractive in the context of a circular economy. Nanoscale biomolecular structures are used for targeted drug delivery, rapid testing, high-throughput gene sequencing, and vaccines' latest generation.

Researchers are exploring ways to mimic photosynthesis, a complex interplay of molecular self-assembly and quantum mechanics, to create novel energy harvesting devices with nearly 100% quantum efficiency.

With the rapidly expanding applications of nanotechnology in the industry, there is a growing need for more versatile, scalable, and sustainable nanofabrication methods. An exciting perspective is the ability to create dynamical nanoscale structures capable of exhibiting a much broader range of functionalities.

To achieve this, scientists are learning from complex biological systems to take advantage of the engineering principles that drive nature's molecular machines.

Canadian VR technology will aid isolation effects on a simulated long duration space flight – CBC.ca

An international team of volunteers has just begun a 240 day isolation experiment in Russia to simulate a long duration space flight like a trip to Mars. A new virtual reality program developed in Canada will be part of the experiment to help fight the effects of isolation.

A unique facility called "NEK" at the Institute of Biomedical Problems of the Russian Academy of Sciences in Moscow, has been used since the 1960s to study the psychological and physical effects of long duration space flights. A series of simulated missions of various lengths have taken place, the most famous, the Mars 500 mission in 2010/2011 in which an all male crew spent 520 days in isolation.

This latest eight month mission, which includes three men and three women, will include a new VR tool developed at the iSpace Lab at Simon Fraser University, in collaboration withthe Centre for Space Medicine and Extreme Environments in Berlin, to help fight the effects of extreme isolation.

Users will wear 3D goggles and experience flyover views of the Earth both looking down from space and through beautiful environments such as mountain forests. The researchers believe the meditative experience will simulate what astronauts call the "overview effect" that comes from looking down on the Earth from space, as well as a sense of awe when visiting beautiful places.

The immersive technology will provide an escape from the confines of the isolated habitat and hopefully mitigate the psychological pressures of living in isolation.

A journey to Mars takes more than a half a year. During that time, a crew will become more and more isolated from Earth as their distance from home increases to 480 million kilometres, creating a time delay of up to 20 minutes for their communication signals to travel between the two planets. They will be isolated in space and in time.

And Martian explorers will have a different experience from long-duration residents of orbital space stations, like Canadian astronauts Robert Thirsk or David St. Jaques, who spent a half a year in space on the International Space Station, or Russian cosmonaut Valeri Polyakov who spent 437 days on the Mir space station in the 1990s.

They could look out the window anytime and see the beauty of the Earth passing 400 kilometres below, and had more direct access to family and friends.

But on a spacecraft headed to Mars, the Earth is out of sight during the voyage and communication will become more delayed as the distance increases. The crew will also be entirely on their own if something goes wrong because a rescue mission would also take months to reach them. It will literally be life in a tin can with no escape. This could create a profound sense of isolation and potentially interfere with their crew responsibilities or result in personality conflicts.

The psychological challenges of isolation can be formidable, not just for Mars explorers but also, as we've seen, for people cut off from family during COVID lockdowns.A virtual experience may help calm the nerves of astronauts in deep space, but it is also a lesson for those of us on Earth who can appreciate the value of a real walk in the woods, on a beach or any place where the power of nature provides a sense of peace.

So when you finish reading this blog, step away from your computer and take a walk outside. It will be good for you.

A broken toilet on SpaceX capsule means astronauts will return to Earth in diapers – NPR

The Crew Dragon space capsule astronauts, from front left, European Space Agency astronaut Thomas Pesquet, NASA astronaut Megan McArthur, NASA astronaut Shane Kimbrough and Japan Aerospace Exploration Agency astronaut Akihiko Hoshide.

The journey back to Earth from space is never easy, but the astronauts aboard the SpaceX capsule coming home Monday will have an extra challenge to deal with: no working toilet. The four members on SpaceX Crew Dragon Endeavor will be wearing diapers as they splash down, in order to prevent anything else from splashing too.

The crew for this mission, known as Crew-2, has been at the International Space Station since April, and have spent nearly 200 days in space. "It's been a very, very intense mission, a lot of things have happened," said expedition commander and French astronaut Thomas Pesquet in a press conference over the weekend. Over the mission, they conducted a series of spacewalks installing solar panels to upgrade the station's powergrid, grew the first green chile peppers in space (and made tacos!) and even hosted a private Russian film crew.

The SpaceX capsule is currently scheduled to undock from the International Space Station on Monday afternoon and return Monday night, although all of that is dependent on the weather. All in all, the four crew members could spend up to 20 hours in the capsule, from the time the hatches are closed until they open again on Earth.

In this weekend's press conference, NASA astronaut Megan McArthur confirmed that the toilets on board Dragon Endeavor are broken. "Of course that's sub-optimal, but we're prepared to manage," she said with a smile. "Space flight is full of lots of little challenges, this is just one more that we'll encounter and take care of in our mission."

This is not the first toilet issue on a SpaceX Dragon capsule. An alarm went off on SpaceX's all-tourist flight earlier this year, signaling a problem with the onboard waste management system. Bill Gerstenmaier, a vice president at SpaceX, later said in a press conference that the spacecraft's urine storage system had become disconnected in flight, allowing pooled urine to enter a fan system. It didn't cause any major problems on that flight.

A similar problem was then found on Crew-2's capsule, which is why it has been taken offline for this return journey home. NASA and SpaceX engineers say they did extensive tests to make sure that the urine leak from April, when the crew was last in the Dragon capsule, would not have harmed the spacecraft over time.

A new SpaceX mission, Crew-3, is set to launch no earlier than Wednesday to continue the work of Crew-2. Gerstenmaier, who was a longtime NASA engineer before joining SpaceX, says that the toilet problem has been fixed for the upcoming launch.

NASA and National Geographic have partnered to help tell the story of the first crewed flight around the Moon in more than a half century.

The agency wants to document and leverage content that will help tell the story of the first crewed Artemis mission, Artemis 2, which is expected to fly humans around the Moon and back to Earth aboard the Orion space capsule. The 10-day mission is slated to lift off atop the second Space Launch System rocket no earlier than May 2024. Aboard will be three NASA astronauts and one Canadian astronaut the first non-American to travel to the Moon.

On Oct. 29, 2021, NASA announced National Geographic won a selection process that started with a call for proposals in November 2020. National Geographic entered into a non-reimbursable Space Act Agreement with NASA to collaborate with the agency on the project.

Returning humans to the Moon with Artemis 2 will inspire the next generation of explorers, Kathy Lueders, associate administrator for the Space Operations Mission Directorate at NASA Headquarters in Washington, who served as the selection official, said in an agency news release. This time, we are bringing partners and technologies that will create additional opportunities for the world to share in the experience along with our astronauts.

National Geographic plans to use lightweight audiovisual hardware flying inside Orion for this one-of-a-kind opportunity to create an immersive experience in hopes of inspiring the next generation of space explorers.

The mega-media company plans to create a multi-platform story-telling campaign using its portfolio of assists, which include magazines, television and digital content, to share the experiences of the astronauts and mission with the world.

For the Artemis program, NASA plans to first launch the uncrewed Artemis 1 mission as early as February 2022, which involves launching an Orion capsule atop a Space Launch System rocket to place the crew-rated spacecraft into a distant retrograde orbit around the Moon.

While there wont be any people aboard, this is expected to be the first time a spacecraft designed for people will travel to the Moon since the last Apollo program Moon landing in 1972.

After about a month, the Artemis 1 Orion spacecraft is expected to return to Earth, splashing down in the Pacific Ocean.

Artemis 2 is set to be the first crewed flight of the SLS/Orion system in hopes of paving the way for future missions to the Moons surface by the middle of this decade in preparation for testing technology and processes needed for human spaceflight to Mars in the 2030s.

Why Is NASA Sending People to the Moon Again? – The Atlantic

Update your calendars, everyone: NASA isnt going to put people on the moon in 2024. The space agency announced yesterday that it is now aiming to send a crew to orbit the moon, Apollo 8 style, in May 2024, and then land astronauts on the surface, la Apollo 11, sometime in 2025.

If your reaction to this news is something like, Wait a second, what? NASA is trying to land people on the moon again?thats fine. There are many, many, many more pressing matters to occupy Americans minds than what NASA may or may not be doing, and when. The Biden administration isnt really talking it up either.

The current moon effort is called Artemis, named for Apollos sister in Greek mythology, and it arose during the Trump administration: After NASA officials made clear, to Donald Trumps annoyance, that they couldnt pull off a Mars landing before the end of his first term, the president pivoted to the moon, and in 2019 directed NASA to land Americans on the lunar surface in 2024, shaving four years off the agencys then-goal of 2028. The Biden administration embraced the Artemis program in February and, until now, NASA had held onto 2024, reworking the previous administrations promise to take the next man and the first woman to the moon to the first woman and the first person of color. The White House has barely breathed a word of it all year. President Joe Biden hasnt publicly name-checked the program, and during a speech at NASAs Goddard Space Flight Center in Maryland last week, Vice President Kamala Harris mentioned only one moon landingone that happened more than 50 years ago.

NASA is getting geared up to go, Bill Nelson, the NASA administrator under Biden, told reporters with enthusiasm yesterday, to plant another flag, to build habitats, to take what astronauts learn on the lunar surface and use it for future missions to Mars. Americans havent visited the moon since 1972, and the remnants of the Apollo landings sit like ghostly ruinsthe American flags bleached white by the suns rays, the boot prints still etched into the regolith, the rovers coated in a thin layer of moon dust. Thats right: Astronauts actually drove on the moon half a century ago. If NASA could do all that then, repeating a moon landing nowwith all the computing power and other technological advances that humanity has amassed in the accruing yearsseems like it should be a breeze.

Read: What is the Apollo 11 landing site like now?

But as the new delay shows, its not. NASA and its commercial contractors are developing an arsenal of new equipment for these missionsrocket, lander, life-support systemsand they have a tremendous amount of work left to do. The spacesuits that NASA began developing in 2007 wont be ready until at least 2025. The agency is not entirely starting from scratchafter all, it did this 50 years ago!but the effort to return to the moon seems almost like a hassle now. So why is America going back at all?

In the 1960s, NASA had the budget, the political will, and the Cold War momentum to sprout a moon program and pull off a landing in a span of eight years. Some administrations since President John F. Kennedys have vowed to returnGeorge W. Bush, for example, called for a landing in 2020but the special circumstances that fueled the Apollo era have vanished. NASAs funding accounts for just half a percent of the annual federal budget, compared with the 4.5 percent the agency enjoyed during the Apollo days. At every presidential election, NASA braces for a new shift in directive; Barack Obama took a been there, done that stance on the moon, before Trump pivoted right back.

John Logsdon, a longtime space historian who attended the Apollo 11 launch, once told me that the national drive that fueled the Apollo era has weakened. That impulse is certainly less widespread than it was 50 years ago, he said. And indeed, our motivations for traveling beyond Earth seem less intuitive now. In my years as a space reporter, most of the questions that have framed my stories about the American space effort have been fairly straightforward. Who? NASA usually, but, more often these days, Elon Musk and Jeff Bezos. What? A rocket, a rover, a telescope. When? T-minus minutes for a rocket, seven months for a Mars-bound probe, years for one heading to Jupiter. Where? A launchpad in Cape Canaveral, inside the rings of Saturn, beyond the asteroid belt. The why has often been more difficult to pin down, particularly for the risky, expensive missions that involve putting a human being on board. But there has always been a feeling of certainty in it. Now that human beings have figured out how to leave the planet and go somewhere else, why would we stop?

A few motivations drive American space travel today, some old and some new: national prestige, geopolitical power, economic opportunity, scientific knowledge. But space exploration can achieve each of those goals only to a limited extent. Certain American politicians warn of a new space race with China, but exploration projects these days rely more on international cooperation. The private sector is developing missions to mine the moon for resources, but the commercial market for them doesnt yet exist. Some argue that space travel can lead to better technology on Earth, but thats difficult to imagine now, when the most recent flashy development on the International Space Station consisted of tacos made with green chiles the crew grew on board. And science and discovery, perhaps the purest motivations, are subject to political whims. The Artemis program didnt transpire because a bunch of lunar scientists got together in a room and decided to do it; it exists because Trump sought to bolster his presidential legacy.

Read: The false hope of an American rocket launch

Ignoring the reality of Americas ambivalence toward space travel is becoming much more difficult. Public-opinion surveys in recent years have shown that Americans want the country to prioritize other kinds of space activities; in a Morning Consult poll published in February, survey participants said the United States should focus more on climate-change research and the study of asteroids that could strike Earth. Only 8 percent said sending astronauts to the moon should be a top priority, and 7 percent said the same for a mission to Mars. Gil Scott-Herons words in Whitey on the Moon, from 1970, still resonate: Cant pay no doctor bill / But Whiteys on the moon / 10 years from now Ill be payin still / While Whiteys on the moon.

For years, NASA has insisted that Americans cared about space exploration anyway, and presented the Apollo effort as a product of national unity. (It wasnt; polling shows that the moon program was unpopular for most of the 1960s, with the exception of a survey conducted in the immediate aftermath of the Apollo 11 landing.) As one space-policy wonk told me recently: Theyve been coasting on the fact that a significant amount of people think that space is cool and they dont have to argue why they do this.

During yesterdays call with reporters, Nelson, the NASA administrator, gave a hodgepodge of the usual reasons for a moon mission: bolstering scientific discovery, providing economic benefits, inspiring future generations of scientists and engineers, beating another nation to it. This time its China, which seeks to land its own astronauts on the moon soon. We have every reason to believe that we have a very aggressive competitor in the Chinese, Nelson said, and we want to be the first back. But by trying to highlight the appeal of space travel on all fronts, NASA risks making its rationale so amorphous that it appeals to no one. Over the years, Ive spoken with many people who think deeply about space travel, and when I ask some of them about the whys, they admit, a little sheepishly, that there might be no compelling reason to send people into spacerobots, yes, but people, maybe not. They seem hesitant to even say it aloud, as if to do so were blasphemous. But we shouldnt be afraid to examine why that is, and even dwell on the ambivalence. And the truth is that the reasons are not so clear.

Read: The coming end of an era at NASA

In the end, NASA doesnt need to sell the greater public on a moon mission, only congressional lawmakers who decide budgets. And the agency has tied its future in space to entrepreneurs who dont really need to provide a rationale to the public either. The CEOs of space companies are not beholden to American taxpayers, even though their companies benefit from taxpayer money (and they can make penis jokes to millions of people on the internet without being fired). Until recently, the Artemis effort was tangled up in a turf war between Jeff Bezos and Elon Musk: Bezoss Blue Origin had sued NASA over the agencys decision to pick Musks SpaceX to build lander technology for Artemis missions. Blue Origin had pitched its own lander too, and the company accused NASA of a flawed selection process. NASA said it couldnt work with SpaceX until the conflict was resolved last week, when a judge ruled against Blue Origins claim. Now that the matter is settled, Nelson said that he and his leadership team will visit SpaceXs facilities in South Texas early next year to inspect the technology that might put Americans on the moon again in 2025.

When you consider their motivations for space exploration, NASA and SpaceX are an unusual pairing. Musk, as Ive written before, can talk forever about the urgency of turning humankind into a multiplanetary species without incurring much resistance. NASA, a government agency, cant rely on such fringe ideas. Public officials must trot out the usual reasoning that has underpinned the American space effort since its beginnings, and present the wonder of space travel as proof that we can meet any challenge on Earth, as Biden said recently. American leaders have ridden this logic for 50 years. In the next 50, they might have to accept that it isnt as compelling as they think, and that the American populace might prefer some more earthly proof first.

Jeff Bezos offered actor Tom Hanks a seat on Blue Origin’s spaceflight for 28 million bucks or something – Firstpost

News18 IndiaNov 08, 2021 12:13:21 IST

Space tourism has been all the rage of late, with a new billionaire shuttling off into the beyond in intervals of what feels like every other week. But newsflash: theres someone who doesnt see what the craze is all about, and its Hollywood superstar Tom Hanks.

In a Jimmy Kimmel interview, Hanks revealed that before William Shatner, he had been offered a Blue Origin flight to outer space by Jeff Bezos but that he had turned it down. You know, it costs like 28 million bucks or something like that. Im doing good, Jimmy, Im doing good. But I aint paying 28 [million] bucks," a PEOPLE report quoted Hanks as saying.

Whats more, Hanks made light of the situation by saying that a 12-minute space flight could be simulated right there as host Jimmy and himself sat in their seats. The 65-year-old actor jokingly bounced around in his seat as if in a space flight to drive home his point.

Further, Hanks quipped that he didnt need to spend 28 million dollars to get the experience of being in a space flight. He said he would perhaps do it if it were free, just to feel the joy of pretending" to be a billionaire. Hanks take is diametrically opposite to that of Shatner.

William Shatner, who starred as Captain James T Kirk in the original Star Trek series, flew to space on 12 October aboard the companys crewed rocket, becoming the oldest ever astronaut.

Ive heard about space for a long time now. Im taking the opportunity to see it for myself. What a miracle," said the 90-year-old actor in a statement by Jeff Bezoss space company. The Star Trek actor had described his trip to the edge of space as the most profound experience." reported AFP.

However, when Shatner was sharing his experience with Bezos, it didnt go quite according to plan. While Shatner spoke about his space experience, Bezos suddenly cut the conversation and turned to a few groups nearby to say, Give me the champagne bottle. Come here. I want one."

The abrupt reaction from Bezos vexed Shatner and made him stop speaking. He then scratched his head and turned away, while Bezos continued to pop the bubbly bottle. The video ends where Bezos turns to put his arm on Shatner.

The rest is here:

ISS swerveed to avoid China space junk. Impact would be devastating. – Business Insider

We are so sorry! We bumped into a system failure and couldnt take your email this time.

Thank you for signing up!

NASA and Russia's space agency adjusted the course of the International Space station (ISS) to avoid a collision with debris that was headed.

The fragment was a remnant of a Chinese weather satellite that was destroyed in a missile test 15 years ago, Roscosmos, the space agency, said in a tweet on Wednesday, around the time it adjusted course.

The debris was due to approach the space station some time on Friday if it hadn't moved.

It was due to enter the "pizza box," a flat, rectangular zone 2.5 miles deep and 30 miles wide around the space station inside which any object is "close enough for concern," per NASA.

"It just makes sense to go ahead and do this burn and put this behind us so we can ensure the safety of the crew," said Joel Montalbano, NASA's space station manager, at a press conference on Tuesday, per The New York Times.

Neither NASA nor Roscosmos said how big the fragment was. While a small fragment may not have significantly damaged the station, large bits of space junk have the potential to cause catastrophic damage.

The maneuver raised the space station's orbit by about a mile (1.2 km), Roscmoscos said in a press release Thursday. The ISS fired its rockets for just over six minutes to get out of the way, the Conversation reported.

It took place just a day before Crew-3 mission astronauts Thomas Marshburn, Raja Chari, Kayla Barron, and Matthias Maurer arrived on the station.

This is the 29th time the space station has had to dodge a piece of space junk, according to The Times.

Space debris is made up of bits of often defunct spacecrafts broken apart in orbit, per NASA. It can travel at speeds up to 17,500 mph, per NASA, about ten times the speed of a bullet.

Even a fleck of paint from a rocket can be dangerous at this speed for instance, if it hits an observation dome.

"Space debris has the potential to cripple the ISS and kill the crew," Robert Frost, Instructor and Flight Controller at NASA, said in a blog post in 2019. But the risk is "highly managed," he said.

Ground-based crews track the biggest pieces of space junk to allow lead time to move the ISS out of the way, as can be seen in this Insider video.

Anything above a third of an inch (1 cm) could penetrate the shields of the ISS's crew modules, according to the ESA. Anything larger than 4 inches (10 cm) could shatter the station to pieces, per ESA.

In this instance, the space junk came from an anti-satellite test conducted in 2007, when China launched a missile against its own weather satellite Fengyun-1C, per NASA.

That collision created about 3,500 pieces of large fragments and many other small ones, per NASA.

It wasn't immediately clear how big were the fragments predicted to cross paths with the ISS this Friday, but ground team only track bigger objects that are bigger than a softball, per NASA.

Collisions with smaller debris can also be damaging and are more unpredictable. In June, NASA said that a small fragment had punched a 0.2-inch (5-millimeter) hole in one of the ISS's robotic arms, Insider's Aylin Woodward previously reported.

Bigger fragments are also getting harder to track as an acceleration of space flight activity has led to a dramatic increase of fragments orbiting the planet.

Last year, NASA moved the ISS after detecting a piece of "unknown space debris" that would have flown within a mile of the space station Insider previously reported.

On that occasion, the astronauts still sealed themselves in a Soyuz rocke capsule, which could act as an escape pod in case the station was damaged.

NASAs Landing and Recovery team recently completed its ninth recovery test at sea and is certified to recover the Orion spacecraft for the Artemis 1 mission next year.

According to NASA, a weeklong test in early November 2021 in the Pacific Ocean aboard the USS John P. Murtha was performed by NASA and Department of Defense teams in order to ensure they are ready to recover the Orion capsule following its splashdown at the conclusion of its roughly month-long uncrewed test flight.

Artemis 1 is currently expected to launch atop the inaugural flight of the Space Launch System no earlier than Feb. 12, 2022, from Launch Complex 39B at NASAs Kennedy Space Center in Florida.

For the past several years, NASA and DoD have been working together to develop the procedures and hardware necessary to safely recover Orion, not only after this uncrewed flight, but also for future crewed missions onboard the spacecraft., said Melissa Jones, NASA recovery director based out of Exploration Ground Systems at Kennedy Space Center in Florida, in an agency release.

Testing and checkouts for recovery of the spacecraft were conducted ahead of Artemis 1, a mission that will send the capsule, built by Lockheed Martin, into a distant retrograde orbit around the Moon.

These system checks are meant to examine the procedures of recovery operations, including the hardware of the capsule.

NASA said once the spacecraft splashes down in the Pacific Ocean, a team of divers, engineers and technicians are expected to depart the ship on small boats to reach the capsule in order to secure it and tow it to the back of the recovery ship. The area the capsule will be towed into is called the well deck where it will be secured for the trip back to shore.

Currently the actual Orion spacecraft for Artemis 1 is fastened atop NASAs Space Launch System rocket inside the Vehicle Assembly Building at NASA Kennedy Space Center in Florida.

The recently fully-integrated system is preparing for final check-outs ahead of the Artemis 1 mission. The next major task for the rocket stack will be a roll out to Launch Complex 39B for a wet dress rehearsal a mock countdown and fueling test before it is returned to the VAB to be readied for its actual flight.
