Building a House of El with Claudia Gray and Eric Zawadzki – GamesRadar

Posted: January 13, 2021 at 4:16 pm

A bold, but divided new Krypton reveals itself in House of El Book 1: The Shadow Threat. Stemming from DC's blooming YA line and headlined by New York Times bestselling author Claudia Gray and cult-favorite illustrator Eric Zawadzki, House of El introduces readers to the world beyond the world we think we know - before the birth of Superman.

Zahn and Sera are two Kryptonians who couldn't be more different. Zahn is a member of the upper crust of Krypton, on track to become one Krypton's lawmaking caste moving then into rule amongst his wealthy and affluent family members who make up one of the planet's most powerful. Sera is a soldier, undergoing missions for the government and restricted to only certain parts of the planet befitting her 'station.'

But when the two become aware of a secret the ruling families of the planet have kept hidden, a secret two Kryptonian scientists by the name of El are struggling to bring to light, they together are thrust into an adventure that has seismic repercussions for the planet and it's strict caste-based society that has driven them to this point.

Newsarama recently got a chance to talk to the creative team of House of El, discussing the process by which the series came about, the design elements of the book, and how the work of creating this Elseworlds-esque new Krypton actually went down. Join us as we enter this new House of El.

Newsarama: How did House of El first come about? Was it something commissioned by the Superman editorial office or was it something independently pitched?

Claudia Gray: Somewhere in-between, I think. I pitched something else, and while they didn't want to go in that direction, they liked the pitch enough to want to talk more about how we might work together. They had a very rough idea for a story about original characters set on Krypton before the explosion and let me run with it.

Nrama: How much design work was done from there? I would assume a large amount of character work was first up to nail down, but how was the look and feel of this particular Krypton developed?

Gray: My starting point for the look of Krypton was the Superman symbol itself - it's a Kryptonian design, so what could that tell me? So, I worked with a lot of angularity, enclosed lines, stronger colors.

And this is a planet that has gotten very far away from nature in every possible sense of the world, one that has ceased to be grounded - so that led to a take on Krypton as a hyper-industrialized, overbuilt planet where people largely live in towers and walkways far above the surface.

Everything after that is thanks to Eric Zawadzki, the brilliant artist who took those few elements and ran with it, creating something that surpassed my most optimistic hopes.

Nrama: Which brings us to Eric actually! Eric, how did your involvement with House of El start?

Eric Zawadzki: The original editor on the project, Alex Carr, had read an indie book of mine, Eternal. He seemed impressed enough with it to reach out to me about getting involved with House of El. Fortunately, I was winding down on Heart Attack at Skybound/Image Comics, so I jumped at the chance.

Nrama: Krypton itself has had a number of visual touchstones and tonalities over the years. How important was it for you that House of El stand out among them?

Zawadzki: Generally speaking, Krypton isn't shown much in media. It's usually the first five pages in a comic or the first 20 minutes of a movie before we move on to the main story. So, I thought it was a pretty big deal to do an entire trilogy of graphic novels devoted to Krypton.

So, I would say that I was very intimidated!

Nrama: Switching back to you, Claudia, we are provided a very divided Krypton in House of El. Both in the lead characters, one representing an "academic, noble house of Krypton" and the other providing a look into a lower born, more tactile Kryptonian life, but in the scene settings as well as readers will see both affluent and unsupported sections of Krypton.

How important was it to explore this dichotomy and was there any push/pull to make either side seem 'right'?

Gray: The dichotomy was essential. This is a planet whose people have completely lost the ability to communicate with each other outside of their houses and castes - the paths in life they're genetically programmed to follow.

Sera and Zahn should never have had any but the most glancing interactions, but the events of the story throw them together and, in the process, give them each a viewpoint on their world they'd never imagined.

There was definitely no need to make one side or another be 'right', because by this point in Krypton's history, every single side is wrong. Only a handful of individuals, from different houses, are able to see beyond the rigid structure of the society they're born into.

Nrama: Krypton also has a very distinct sense of fashion, but with House of El, you Eric bring a whole new level of sartorial chicness to the costumes, but one still clearly rooted in 'classic Kryptonian looks.' Can you talk a little about the process of costuming the cast?

Zawadzki: I found that in a lot of interpretations of Krypton, artists really leaned into the spandex approach, inspired by Superman's iconic costume. I have a little bit of that in this series, but I wanted to find some distinctive clothing themes to make this series different from everything before it.

Also, I was presented with the challenge of making sure the lower and upper castes were distinctive from each other. Generally speaking, I made sure the lower caste wore more functional, plain-looking outfits, while the upper castes tended to wear more outrageous, haute couture-inspired clothing.

Nrama: Claudia, how much research was done prior to starting active development?

I would imagine there would be some desire to make sure you don't overwrite anything already established by Kryptonian society, but at the same time House of El reads and feels so wholly like its own thing, I was curious to see if there were any major influences there.

Gray: My DC editors strongly encouraged us not to rely on past influences. They wanted us to write it as though it hadn't been written before. I'm so grateful for that--not only for the trust they showed in us, but also because, if I'd spent too much time looking at so many brilliant previous takes on it, I'd probably have been intimidated into a fatal case of writer's block.

Nrama: Eric, you also provide House of El a very dense, intricate architectural design. How did you even start to tackle the buildings and vehicles?

Zawadzki: There was a bit of a guidepost given to me by Claudia in how the city is built. (which you'll see in book 2) So I used that as a jumping-off point. The planet is built around hierarchy, so I challenged myself to do something different than what I'd seen many times in other media depicting a similar society.

I ended up designing the city as a series of platforms stacked on top of each other, with various walkways and stairs uniting them. Because Krypton has technology that creates and repairs these structures, I wanted a kind of uniform look where there are patterns of overlapping planks of metal that wrap around and grow on top of these structures. And, overall I just wanted to depict a vast, detailed city that feels alive.

Nrama: Claudia, how was this first volume scripted?

We know that this is the opening of a larger House of El series that readers will get to experience eventually, but was this first book written in a 'vacuum' to be enjoyed as its own start to finish story or was it all written into one longer sequence?

Gray: To me it feels very much like the first part of a trilogy - the last page should leave you wondering what happens next. It's such a huge thing to ask of readers, but hopefully they'll come along for the ride.

Nrama: With House of El being an original trilogy, was there any desire to make them all a followed through narrative? Meaning, was there any drive to add in little bits and bobs of story in Vol. 1 to pay off in later volumes, or was it more internally focused as you tackled each volume?

Gray: Honestly, it's one big story, told in three episodes that hopefully each feel like a complete adventure on their own. But the links and payoff are definitely both within each book and among all three of the books.

Nrama: Eric, you've also been paired up here with the wonderful colorist Dee Cunniffe, did you find yourself giving them a little visual 'runway' in the way you laid out various pages?

Zawadzki: I've worked with Dee several times in the past, so I was happy to have him on board. I always feel like he saves me, making my work look better than it actually is. I generally try to get out of his way and let him do his thing. He developed some new skills and a new style specifically for this project and I couldn't be happier with it!

Nrama: Though this series is an original, out-of-continuity take on Krypton, did you find yourself taking any visual cues from other Superman or Krypton based stories? I personally saw a lot of P. Craig Russell and Jerry Ordway in your artwork.

Zawadzki: I'm honored to be compared to such artistic heavyweights! I was very intimidated in the beginning and I like to be prepared, so when I was hired for the project, I saw it as my responsibility to do my research and view as many artistic interpretations of Krypton as possible.

I particularly enjoyed what John Byrne and Gene Ha visualized. But when I sent some early sketches to editorial, they made it very clear to me that they preferred that I made this as unique as possible and make it 100% my own. So from that point on, I stopped my research. I think it's a smart approach, being beholden to nothing from the past, as it provides an antithesis to the continuity-heavy main DC line of books.

Nrama: Claudia, let's talk about your leads. We are introduced early to Zahn (a member of the Scholar/Law Class) and Sera (a Kryptonian soldier), both working strictly within their casted assignments on Krypton, but how were they conceptualized at first?

Did you come at them first from their ideological standpoints first or was it a matter of thinking what Kryptonian youth would feel/act like?

Gray: They both sprang out of the core concept of genetic engineering, of a society that essentially bred its children to be exactly what their parents expected, exactly what their parents were themselves. So that meant both characters very much needed to be exemplars of a very certain type of programming, something that would be instantly relatable to the reader.

From that, it became, okay, which segments of society should they belong to in order to best further the story? I needed people in dramatic positions - and I also needed to create links to the canonical characters of Jor-El, Lara, and Zod. So, Zahn became a relative of Lara's, and Sera became a minion of Zod's.

Nrama: As with most Krypton related stories, House of El carries a heavy sense of dread throughout the whole first volume. Was this intentional or just a happy accident since you were already dealing with DC's most famous doomed planet?

Gray: It's definitely intentional. Zahn and Sera are discovering just how much genetic engineering has wounded their society - and, inevitably, that's going to lead to the ultimate expression of that, i.e., Krypton's inability to understand that it's doomed in time to save its people.

Nrama: Eric, you also wonderfully parse the rapidly changing climate and look of the environment of Krypton. Did you have to set these pages or sequences apart from the 'main' action of the piece or just take it on as the pages arrived?

Zawadzki: I was given a 180-page completed script when I signed on to the project, which is unlike anything I've worked on prior. Usually, I'm only given 20 or so pages at a time. This allowed me to prepare for sequences months in advance of working on them.

Unfortunately, there's just never enough time. Especially when you're designing an entire world and culture! So I basically take it page by page and do my best. If it were entirely up to me, I'd probably still be doing design and prep work to make things much better. And the books would never come out! Which is why deadlines are good for me.

Nrama: So with this being the opening of the House of El trilogy, what else can we expect at least visually from the rest of the volumes? No Spoilers, of course!

Zawadzki: Expect to see more destruction and see more of how Krypton works. And I have to say, I had a lot of fun on book two illustrating our two leads getting to know each other better. Lots of great acting opportunities given to me by my brilliant partner in crime, Claudia Gray!

Nrama: Claudia, early on in Book 1, Sera is faced directly with the caste system and her "inferior" station on the planet compared to "the elite" society of Krypton, but displays almost a radical empathy and almost pity toward the people she protects, calling herself the "shield that protects Kryptonians from everything".

To me, this sounds VERY Superman but with a stronger sense of civic pride. Were there moments throughout the scripting of this series where you thought "What would Kal-El do or think?" in these situations?

Gray: No, I didn't think too much about that--because, as Jor-El and Lara make clear (spoilers ahoy!), Superman does not share the genetically programmed elements of Krypton. They conceived him naturally. So while he obviously has some of his parents' traits, he would be as much of a misfit on Krypton as Zahn is. What we see as Superman's virtues would there be seen as Kal-El's weaknesses.

I agree that he'd share that sense of protectiveness and empathy toward the people of Krypton, but he'd be mocked for it and would be denied most opportunities to act on that feeling. And that isolation might have led to a very different personality than the one we know and love as Superman.

Nrama: Finally, thank you both so, so much for taking the time to talk to us. I want to leave on, what do you hope readers take away from House of El?

Gray: Thanks for talking with me! I hope readers take away a new view of Krypton, and can actually imagine themselves there--and can recognize the few, but real, parallels between their mistakes and our own.

Critical but Little-Known Facts About the COVID-19 Pandemic – Physician’s Weekly

Posted: at 4:16 pm

New information is published almost daily about the coronavirus pandemic.

Since the beginning of the coronavirus pandemic, there have been many thousands of articles and commentaries published on almost every imaginable aspect of the SARS-Cov-2 virus and the COVID-19 pandemic it has caused. They have appeared online, in journals, on preprint servers, in newspapers, and on blogs. As much as we might try to keep up, there will always be important facts or developments we might have missed, so below are a few that should help us understand some of the nuances of the pandemic.

#1 THERE APPEARS TO BE AN IMPORTANT DIFFERENCE IN EFFICACY BETWEEN THE Pfizer-BioNTech AND Moderna COVID-19 VACCINES.

The difference pertains to the efficacy across different demographic groupsspecifically, people of different ages. According to theFDAs analysisof the Pfizer-BioNTech vaccine, in the clinical trials on almost 44,000 subjects, it was 95.0% effective in persons aged 16-55, and 93.8% effective in those over age 55that is, essentially the same. By contrast, regulatorsreviewof the clinical studies with the Moderna vaccine found a pronouncedage-dependent difference: The [Vaccine Efficacy] in participants 65 years of age appears to be lower than in younger adults 18 to <65 years (86.4% compared to 95.6%) (emphasis added).

That is shown in the indicated portion of this table, from anarticlein the New England Journal of Medicine that reported the results of Modernas clinical trials:

Thus, of every hundred people under age 65 vaccinated with the Moderna vaccine, we can expect that about five will fail to develop an immune response after the two shots; among those 65 or over, about 14 will not be successfully immunized. (The failure rate for the Pfizer-BioNTech vaccine was approximately five in a hundred for all age groups.) The numbers are small, but the bottom line is,if youre 65 or older and you have a choice, Id recommend that you get the Pfizer-BioNTech vaccine.

#2 VACCINES ABILITY TO PREVENT SYMPTOMATIC COVID-19 IS NOT THE SAME THING AS COMPLETELY PREVENTING THE ESTABLISHMENT OF INFECTION (WHICH IS CALLED STERILIZING IMMUNITY).

Because of how the trials were designed, efficacy was defined as a positive test for the SARS-CoV-2 virus genetic material (RNA) and at least one symptom, such as fever, cough, fatigue, or loss of taste or smell. But that doesnt rule out the possibility that people who are successfully vaccinated (no positive test for the virus and no symptoms) could become infected and spread the virus to other people. Given that possibility, and also (as discussed above) the reality that fewer than 100% of people given the shots will be protected,it is essential that we continue to practice the non-pharmaceutical preventive measures: masking, social distancing, frequent handwashing, and avoiding crowds in enclosed spaces.

Going forward, we will need to know about the impact of vaccines on virus transmission, but for that, we will need new clinical studies with contact tracing to monitor the spread from vaccinated and unvaccinated participants. (One suggestion, by biostatistician Natalie Dean, is to design such a study using college students, because they arent prioritized for [receiving vaccine under the Emergency Use Authorizations], and transmission is higher in congregate settings.)

#3 CORONAVIRUS VACCINES ARE NOT NEW.

Coronavirus infections are common in companion animals and economically important livestock andvaccines to prevent these infections have been widely employedin veterinary medicine for many years. They have been administered to dogs, cattle, pigs, and poultry. (The animal coronaviruses are sufficiently different from SARS-CoV-2 that the veterinary vaccines would not prevent COVID-19 in humans.) Themore than a dozen veterinary vaccineslicensed in North America have been developed with an array of technologies and platforms, including genetic engineeringbut none, as yet, with the messenger RNA technology (mRNA) used for the Pfizer-BioNTech and Moderna vaccines.

#4 THE NOVEL TECHNOLOGY TO MAKE THE APPROVED COVID-19 VACCINES ISNT FUNDAMENTALLY NEW.

Many reporters and commentators have dutifully noted that vaccines have traditionally been composed of killed or attenuated (weakened) viruses so that they can elicit an immune response without causing disease. The Pfizer-BioNTech and Moderna COVID-19 vaccines, however, are made with a genetic engineering technology called messenger RNA (mRNA), which acts in anovel way. When injected into a persons muscle, the mRNA is read by the cells protein-synthesizing machinery and gives rise to numerous copies of a version of the SARS-CoV-2 virus spike protein, which is on the surface of the virus and plays a key role in attaching to the hosts cells.

An understanding of this continuum of approaches to vaccination should help to demystify COVID-19 vaccines for the considerable number of people who may be hesitant about taking a novel vaccine developed and approved in record time.

Those proteins elicit an immune response, so that if the person who has been injected subsequently comes into contact with the infectious SARS-CoV-2 virus, the bodys antibodies and immune cells are prepared to neutralize it.

However, theres a link missing in that narrative about the continuum from traditional vaccine development techniques to mRNAnamely, subunit vaccines, which are conceptually similar to using mRNA for vaccines. A good example is Mercks hepatitis B vaccineRecombivax, which has been around for more than 30 years. What is injected and stimulates the immune response in that case is a non-infectious viral protein that is synthesized in genetically engineered bakers yeast grown in huge fermentation vats. The protein, which is analogous to the coronavirus spike protein, is purified and used as the active substance in the vaccine.

A similar example is GlaxoSmithKlines shingles vaccineShingrix, which contains a glycoprotein (a protein linked to a carbohydrate) that is a component of the varicella zoster virus, and which is synthesized in genetically engineered Chinese hamster ovary cells.

There is also a COVID-19 vaccine using this technology being developed by Maryland-based Novavax. It containsproteins produced in genetically engineered insect cellsthat resemble the spike proteins found on the surface of the coronavirus, and which elicit an immune response after being injected.

The Merck, GlaxoSmithKline, and Novavax subunit vaccines are something of an intermediate approach between the killed or attenuated vaccines and the mRNA ones because the antigen injected is a protein, whereas the mRNA vaccines cause a protein to be synthesized in the vaccine recipient after injection. An understanding of this continuum of approaches to vaccination should help to demystify COVID-19 vaccines for the considerable number ofpeople who may be hesitantabout taking a novel vaccine developed and approved in record time.

#5 THE MONOCLONAL ANTIBODY DRUGS TO TREAT COVID-19 ARE GOING BEGGING.

In November, the FDA issued two Emergency Use Authorizations for monoclonal antibody drugs produced byEli LillyandRegeneron Pharmaceuticals, respectively, that treat mild to moderate cases of COVID-19 in adults and older pediatric patients at high risk for progressing to severe illness. They are expensive, and in short supply, but paradoxically, U.S. health officials are seeing a lack of demand for these drugs that can help to keep infected people out of the hospital.

If you are diagnosed with COVID-19, have symptoms, and qualify for these [monoclonal antibody] drugs, insist on getting them immediately.

Testing delays (they need to be infused intravenously within 10 days of the onset of symptoms), red tape, and shortages of staff for intravenous administration arepreventing many patientsfrom getting these drugs, which consist of laboratory-produced antibodies that mimic those produced in response to infection. ThisWall Street Journal headlinesays it all: Highly Touted Monoclonal Antibody Therapies Sit Unused in Hospitals.

There is an important news you can use message here:If you are diagnosed with COVID-19, have symptoms, and qualify for these drugs, insist on getting them immediately.

#6 THE NEW, MORE INFECTIOUS U.K. SARS-CoV-2 VARIANT (B.1.1.7) IS MORE DANGEROUS, EVEN IF NOT MORE VIRULENT.

Much of the reporting about this new variant of the SARS-CoV-2 virus, B.1.1.7, which has quickly become the predominant strain in parts of the U.K. and has now been detected in about three dozen other countries worldwide, including in various parts of the United States, has characterized it asmore transmissible, but not more deadly. Preliminary analyses suggest it isin the range of 56%-70% more transmissiblethan other circulating SARS-CoV-2 strains. However, that characterization is misleading in two respects.

First, the more transmissible the virus is, greater numbers of people will be infected and will be hospitalized, and morein the sense of absolute numberswill die. Thus,although perhaps not more likely to kill a particular individual who becomes infected, overall, the death toll from the viral variant will be higher because of its ability to infect more people.

Second, as World Health Organization epidemiologist Maria Van Kerkhovehas pointed out, The more of this virus circulates [because of greater transmissibility], the more opportunity it will have to change to something worse. She concluded, Were playing a very dangerous game here.

#7 WHEN SOMEBODY TELLS YOU THAT ITS SILLY TO IMPOSE LOCKDOWNS OR TAKE VACCINES BECAUSE OF AN ILLNESS WITH A SURVIVAL RATE OF 99.9%, YOURE ABOUT TO BE SOLD A BILL OF GOODS.

First of all, a conservative estimate of the death rate is not 0.1% (which would correspond to a survival rate of 99.9%), but probably well above 0.2%. That might not sound like a lot, but when applied to a huge number of cases, it can be catastrophicas it has been: COVID-19 haskilled 375,000 Americans, been diagnosed in over 22 million, and certainly infected several times that number.

Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning.

Second, herd immunity, the point at which a sufficiently large fraction of the population is immune to infection because of natural infection or vaccination and causes the pandemic to wane, is thought to be upwards of80%in the case of COVID-19.In the absence of vaccines, achieving herd immunity would require the infection of approximately 264 million Americans, which would result in an unimaginable death toll.

Moreover, deaths and death rates are far from the whole story. The persistence of symptoms for months after recovery from the acute illness of COVID-19 is common, even in people who have suffered only mild cases of illnesses.According to the Mayo Clinic, the most common persistent signs and symptoms are fatigue, shortness of breath, cough, joint pain, and chest pain; and the virus can damage the lungs, heart, and brain, which increases the risk of long-term health problems.

We have come a long way in understanding COVID-19, but much remains unknown. As British Prime Minister Winston Churchill said about World War II, at the end of 1942, Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning. As to the COVID-19 pandemic, the scientific and medical communities in the public and private sector will continue to produce important new products and knowledge so we can get to the end as quickly as possible. In the meantime, it is more important than ever to heed their advice about taking precautions toflatten the curve.

iTHRIV Distributes $200000 to Fund Innovative Medical Research Projects – UVA Today

Posted: at 4:16 pm

The integrated Translational Health Research Institute of Virginia, oriTHRIV, a National Institutes of Health-funded Clinical and Translational Research Award hub, has awarded $200,000 in pilot funding to five multi-institutional research projects in Virginia.

Teams of physicians, researchers and engineers at the University of Virginia, Virginia Tech, Inova Health System and Carilion Clinic were awarded the funds as part of the iTHRIV NIH-NCATS award UL1TR003015. Support of these early phase research projects will help accelerate the discovery of potential treatment options for Parkinsons disease, celiac disease and epilepsy, as well innovation in the fields of telemedicine and pediatric heart transplant.

The awarded pilot projects include:

Sana Syed, an assistant professor in theUVA School of MedicinesDepartment of Pediatrics, and Suchitra Hourigan,Inova Childrens Hospitalsvice chair of research and innovation, seek to determine if machine learning is useful in diagnosing celiac disease sub-types.

Currently, treatment and management of celiac disease involves a gluten-free diet and is not intended to help assess the specific risk of patients developing other diseases. Syed and Hourigan will investigate gut tissue biopsies as well as genetic markers of patients with celiac disease and type 1 diabetes and/or hypothyroidism. They aim to determine whether biopsy or gene markers at the time of disease diagnosis can predict the risk of developing these diseases in the future.

The team will use machine learning algorithms to analyze multiple datasets. If successful, the team members hope that any patterns found will enable them to link biopsies and unique genes, paving the way for improved care for patients with celiac disease.

In most instances, how medications act on the brain to produce their therapeutic effect (for instance, pain relief) is not well understood. Aashit Shah, a professor of internal medicine at theVirginia Tech Carilion School of Medicine, and Sujith Vijayan, an assistant professor in the Virginia Tech College of SciencesSchool of Neuroscience, will study patients with intractable epilepsy who have been implanted with electrodes to determine the region responsible for their seizures.

The team will study signals measured in epileptic patients undergoing intracranial electroencephalography. They will review intracranial electrical signals from various brain regions following administration of medications that work on the brain. Shah and Vijayan hope to improve the understanding of how and where these medications work.

They anticipate this can help in the development of new biomarkers for neuroactive drugs, which may improve development of medications in the future.

Della Williams, a neurologist atCarilion Clinicand an assistant professor of internal medicine at the Virginia Tech Carilion School of Medicine, has also partnered with Vijayan to study auditory therapy for patients living with Parkinsons disease. Their project seeks to better understand the disease progression and if it can be slowed by providing background noise to patients as they sleep.

Additionally, simple auditory stimulation during sleep may help to improve learning and memory processes.

Elham Morshedzadeh, an assistant professor of industrial design in Virginia TechsCollege of Architecture and Urban Studies; Andre Muelenaer, a professor ofbiomedical engineering and mechanicsin Virginia Techs College of Engineering and a professor of pediatrics for the Virginia Tech Carilion School of Medicine; and Melinda Schriver, Carilions director of digital health, have proposed a study to design a successful and comprehensive telemedical encounter for infants and preschool children.

Theyll seek to provide a robust, feasible and affordable training program integrating augmented reality, online and hands-on learning experiences. The study aims to make telemedical encounters vastly more inclusive and efficient.

Heart transplantation is the standard of care for pediatric patients with end-stage heart failure or inoperable congenital defects, yet nearly 20% of patients die while on the waiting list.

To help increase the odds of successful pediatric heart transplants, Michael McCulloch, an associate professor and a pediatric cardiologist atUVA Childrens Hospital Heart Center, and Michael Porter, an associate professor of systems engineering inUVAs School of Engineering and Applied Science, will analyze donor echocardiographic data to identify which donor characteristics contribute to positive heart transplant recipient outcomes.

iTHRIV is a cross-state translational research institute which combines the expertise of clinical translational biomedical researchers and data scientists to create infrastructure and investigator resources for using data to improve health across the Commonwealth of Virginia. Partner sites include University of Virginia, Virginia Tech, Carilion Clinic and Inova Health System.

22nd Century Group Expands VLN Tobacco Growing Program to Support Anticipated Demand of the Company’s Reduced Nicotine Content Cigarettes -…

Posted: at 4:16 pm

WILLIAMSVILLE, N.Y., Jan. 12, 2021 (GLOBE NEWSWIRE) -- 22nd Century Group, Inc. (NYSE American: XXII), a leading plant-based, biotechnology company that is focused on tobacco harm reduction, very low nicotine content tobacco, and hemp/cannabis research, announced today that the Company will significantly expand its growing program for VLN reduced nicotine content tobacco based on the Companys latest sales projections. This new planting for VLN tobacco is in addition to the Companys sizeable inventory of VLN tobacco, which is earmarked for the launch and initial sales of 22nd Centurys VLN reduced nicotine content cigarettes. 22nd Centurys Modified Risk Tobacco Product (MRTP) application for VLN cigarettes is currently in the final stage of review with the U.S. Food and Drug Administration (FDA). Once authorization is granted, 22nd Century will begin marketing its VLN cigarettes, which contain 95% less nicotine than conventional cigarette brands. Having the only combustible cigarette with a modified exposure claim authorized by the FDA could serve as a catalyst for 22nd Centurys commercial sales as capturing even a small fraction of U.S. tobacco sales could result in exponential growth in the Companys revenues and market capitalization.

We are prepared to launch our VLN cigarettes within 90 days after receiving marketing authorization from the FDA, said James A. Mish, chief executive officer of 22nd Century Group. There are more than 34 million smokers in the United States and research shows that a majority of these smokers are looking for alternatives. When shown samples of VLN, 60 percent of adult smokers in our studies indicated an interest in using VLN cigarettes. Additionally, in a 2019 U.S. Center for Disease Control and Prevention (CDC) survey, 80 percent of U.S. smokers favored reducing nicotine levels in cigarettes. We believe adult smokers will be very interested in VLN, and this new crop of VLN tobacco will help us to fulfill the expected demand based on our latest sales projections.

Mish continues, In addition to introducing VLN to smokers in the U.S., we are absolutely committed to licensing our technology to every cigarette manufacturer, so that they can comply with the FDAs plan to make all cigarettes non-addictive. We look forward to the tobacco industry joining our efforts to truly reduce the harm caused by smoking and protect future generations from ever becoming addicted to cigarettes.

In partnership with select tobacco farmers, 22nd Century will plant this new VLN tobacco throughout the U.S. tobacco belt, thereby creating a new income stream for Americas struggling family farmers. The Companys proprietary, reduced nicotine content tobacco contains, on average, just 0.5 milligrams of nicotine per gram of tobacco - a remarkable reduction in nicotine versus conventional cigarette tobaccos which often contain 20 mg to 30 mg nicotine per gram of tobacco.

Biochemist Benjamin Tu Honored With ODonnell Award From TAMEST – Newswise

Posted: at 4:16 pm

Newswise DALLAS Jan. 13, 2020 Benjamin Tu, Ph.D., a professor of biochemistry at UT Southwestern whose basic science research into cellular function could lead to greater understanding of diseases including cancer, has been named a recipient of the 2021 Edith and Peter ODonnell Award in Science, presented by The Academy of Medicine, Engineering and Science of Texas (TAMEST).

TAMEST presents the annual awards to recognize the achievements of early career Texas investigators in the fields of science, medicine, engineering, and technology innovation. This years awards were announced today during the final day of its annual conference, which was held virtually. The awards come with a $25,000 honorarium and an invitation to make a presentation before TAMEST members. Tu will make his virtual presentation Feb. 24.

Tu is the 15th scientist at UT Southwestern to receive the award since TAMEST initiated the ODonnell Awards in 2006.

Its an honor to be selected, Tu says of the prize. It was certainly welcome news during very challenging times.

The Edith and Peter ODonnell Awards are given to scientists for their contributions addressing the essential role that science and technology play in society, and whose work meets the highest standards of exemplary professional performance, creativity and resourcefulness, according to TAMEST.

We believe Dr. Tus research will lead to future therapeutic advancements for diseases, saysDavid E. Daniel, Ph.D. (NAE), 2021TAMESTboard president.As a pioneer in his field, we are honored to recognize him as the recipient of our 2021 ODonnell Award in Science and are grateful for the discoveries he is making here in Texas that will impact the rest of the world.

Margaret Phillips, Ph.D., professor and chair of biochemistry, nominated Tu for the award. Ben is an incredibly talented scientist, Phillips says. You could almost see him as a detective. He digs into the nuts and bolts of how cells are functioning and regulating themselves.

Tus research focuses on how metabolism regulates cellular functions. Two of his recent areas of investigation have obvious potential for future advances in clinical treatment.

In two 2019 studies, both published inCell, Tu reported that ataxin-2, a protein with a known link to ALS, or Lou Gehrigs disease, is necessary for cells to do the work of clearing out damaged or unneeded parts in a process known as autophagy. Without the protein, cells are more likely to die, he said

In a2011 study published in Molecular Cell, Tu described how the metabolite acetyl-CoA plays a key role in turning on the genes necessary for cell growth.

At the time, few scientists accepted the idea that a metabolite could have such an important role in regulating gene expression, says Tu. Historically, the field had thought that transcription factors (proteins involved in transcribing the genetic information contained in DNA) dictate what genes are turned on.

This new understanding of the importance of acetyl-CoA led to further research by Tu and a 2014Cellpaper that reported how the metabolite might be important for the survival and growth of liver cancer cells. His current research in mice will investigate if chemicals that inhibit acetyl-CoA might slow the growth of pancreatic cancer cells.

Tu came to UT Southwestern in 2004 after receiving masters and bachelors degrees in chemistry from Harvard University and a Ph.D. in biochemistry and biophysics from the University of California, San Francisco. He worked as a postdoctoral fellow under Steven McKnight, Ph.D., professor of biochemistry, before joining the UTSW faculty as an assistant professor of biochemistry in 2007. Tu holds the Martha Steiner Professorship in Medical Research, and is a W.W. Caruth, Jr. Scholar in Biomedical Research.

His previous honors include the Norman Hackerman Award in Chemical Research from The Welch Foundation in 2014 and recognition as a three-time finalist for the prestigious Blavatnik Awards for Young Scientists in 2017, 2018, and 2019. He is also a UT Southwestern Presidential Scholar.

TAMEST, founded in 2004 by then-U.S. Sen. Kay Bailey Hutchison and two Texas Nobel Laureates Michael Brown, M.D., of UT Southwestern, and Richard E. Smalley, Ph.D., of Rice University strives to bring together the states brightest minds. Members include the Texas-based members of the National Academies of Medicine, Engineering, and Sciences; the Royal Society; and Texas 11 Nobel Laureates.

New quantum particle may have been accidentally discovered – New Atlas

Posted: at 4:15 pm

By definition metals and insulators are very different but now Princeton physicists have accidentally discovered an unexpected quantum behavior in an insulator that was thought to be unique to metals. The find suggests a brand new type of quantum particle, which the team calls a neutral fermion.

Basically speaking, metals conduct electricity and insulators dont. On the molecular level, that comes down to how freely electrons can move through the materials in metals, electrons are very mobile, while insulators obviously have high resistance that prevents them moving much.

As a side effect of this, metals can exhibit a phenomenon known as quantum oscillations. When exposed to a magnetic field at very low temperatures, electrons can shift into a quantum state that causes the materials resistivity to oscillate. This doesnt happen in insulators, however, since their electrons dont move very well.

Or at least that was the conventional thinking for the better part of a century. In the new study, the Princeton researchers accidentally discovered quantum oscillations in an insulator for the first time.

The team was working with tungsten ditelluride, which behaves like a metal in bulk but becomes an insulator when its shaved down into a two-dimensional form like graphene. While measuring the resistivity of the monolayer material under a magnetic field, they found that it began to oscillate.

This came as a complete surprise, says Sanfeng Wu, senior author of the study. We asked ourselves, Whats going on here? We dont fully understand it yet.

The phenomenon cant be explained by current theories, but the researchers have put forward their own hypothesis. They say it may not be the electrons themselves that are oscillating. Rather, the strong interactions might be creating create new quantum particles that exhibit the observed effect.

Since insulators block charged particles, like electrons, from moving freely, these new particles would have to have a neutral charge. These hypothetical neutral fermions could then exhibit the observed quantum oscillations.

If our interpretations are correct, we are seeing a fundamentally new form of quantum matter, says Wu. We are now imagining a wholly new quantum world hidden in insulators. Its possible that we simply missed identifying them over the last several decades.

The team says that more work will need to be done to verify if neutral fermions do exist, or if theres some other explanation for the observed oddities.

The research was published in the journal Nature.

Exploring the unanswered questions of our universe with quantum technologies – University of Birmingham

Posted: at 4:15 pm

The University of Birmingham is a key partner in three quantum technology projects awarded funding from UK Research and Innovation (UKRI). The funding is part of a 31 million investment to demonstrate how quantum technologies could solve some of the greatest mysteries in fundamental physics.

The projects are supported through the Quantum Technologies for Fundamental Physics programme, delivered by the Science and Technology Facilities Council (STFC) and the Engineering and Physical Sciences Research Council (EPSRC) as part of UKRIs Strategic Priorities Fund.

This is a new programme which aims to demonstrate how the application of quantum technologies will advance the understanding of fundamental physics questions. It is supported by the Quantum Technology Hubs comprising the UK National Quantum Technologies Programme

The three projects awarded funding are:

Searching for variations of fundamental constants of nature

QSNET is a multi-disciplinary consortium which aims to search for spatial and temporal variations of fundamental constants of nature, using a network of quantum clocks. Led by Dr Giovanni Barontini, from the University of Birmingham, and partnered with the National Physical Laboratory; Imperial College London; University of Sussex; Max Planck Institut fuer Kernphysik; Physikalisch-Technische Bundesanstalt; Istituto Nazionale di Ricerca Metrologica; University of Delaware; University of Tokyo and the Observatoire de Paris. The project, which has received 3.7 million in funding, is also linked to three of the Quantum Technology Hubs in the UK National Quantum Technologies Programme.

QSNET proposes to build a national network of advanced atomic, molecular and highly-charged ion clocks. The network will achieve unprecedented sensitivities in testing variations of the fine structure constant and the electron-to-proton mass ratio. These are two of the parameters of the Standard Model of particle physics, which is the pillar of our understanding of the Universe, but that famously fails to describe 95% of its content: the so-called dark matter and dark energy. QSNET will test the fundamental assumption that the constants of the Standard Model are immutable, as this could be the key in solving the dark matter/dark energy enigma.

Investigating dark matter and detecting gravitational waves

The Atom Interferometer Observatory and Network (AION) is a consortium project comprising Imperial College London, Kings College London, the University of Oxford, the University of Cambridge, STFC Rutherford Appleton Laboratory, the University of Liverpool and the University of Birmingham.

This interdisciplinary team of academics will develop the science and technology to build and reap the scientific rewards from the first large-scale atom interferometer in the UK. This programme of research will enable a ground-breaking search for ultra-light dark matter and pave the way for the exploration of gravitational waves in a previously inaccessible frequency range, opening a new window on the mergers of massive black holes and novel physics in the early universe.

The University of Birmingham team, led by Dr Michael Holynski, Prof Kai Bongs, Dr Mehdi Langlois, Dr Samuel Lellouch, Sam Hedges and Dr Yeshpal Singh will bring their atom interferometry expertise to AION and focus on realising new levels of large momentum transfer to enable the exquisite sensitivity required to achieve the scientific goals of the project, while also providing leadership on the realisation of economic impact.

The AION project, which has been awarded 7.2 million in funding, will be linked to the UK National Quantum Technologies Programme through the UK Quantum Technology Hub Sensors and Timing, led by the University of Birmingham, and project work will be undertaken at the Hubs Technology Transfer Centre. This will be an opportunity for matter-wave interferometry and strontium optical clocks technology to be developed with industry through to commercialisation.

Quantum-enhanced interferometry for new physics

The Quantum Interferometry (QI) collaboration aims to search for dark matter and for quantum aspects of space-time with quantum technologies. The international QI consortium, led by Cardiff, includes the Universities of Birmingham, Glasgow, Strathclyde, and Warwick in the UK, MIT, Caltech, NIST, and Fermilab in the US, DESY and AEI Hannover in Germany.

QI will build four table-top experiments (two of them in Birmingham) to search for dark matter in the galactic halo, improve 100-m scale ALPS light-shining-through-the-wall experiment at DESY with novel single photon detectors, search for quantisation of space-time, and test models of semiclassical gravity. These experiments will allow us to explore new parameter spaces of photon dark matter interaction, and seek answers to the long-standing research question: How can gravity be united with the other fundamental forces?

The project is linked to two UK National Quantum Hubs and will apply state-of-the-art technologies, including optical cavities, quantum states of light, transition-edge sensors, and extreme-performance optical coatings, to a broad class of fundamental physics problems. Dr Vincent Boyer, Dr Haixing Miao and Dr Denis Martynov will be leading the 4 million-funded project from the University of Birmingham.Visit QI Labs for more information.

Professor Kai Bongs, Principal Investigator at the UK Quantum Technology Hub Sensors and Timing, led by the University of Birmingham, says: The UK Governments investment in these projects enables us to draw together experts in quantum physics research to explore some of the key mysteries of our universe. These projects will allow us to build on the momentum already generated through the Quantum Technology Hubs and build a pipeline feeding novel technologies into the future multi-bn Quantum Technology economy.

Science Minister Amanda Solloway said:As we build back better from the pandemic, its critical that we throw our weight behind new transformative technologies, such as quantum, that could help to unearth new scientific discoveries and cement the UKs status as a science superpower.

Todays funding will enable Birminghams most ambitious quantum researchers to use the precision of atomic clocks to help solve important unanswered questions about our universe, such as detecting dark matter and understanding the 95% of unaccounted energy content of the universe.

Announcing the awards, Professor Mark Thomson, Executive Chair of the Science and Technology Facilities Council, said: "STFC is proud to support these projects that utilise cutting-edge quantum technologies for novel and exciting research into fundamental physics.

Majorscientific discoveries often arise from the application of new technologies and techniques. With the application of emerging quantum technologies, I believe we have an opportunity to change the way we search for answers to some of the biggest mysteries of the universe.These include exploring what dark matter is made of, finding the absolute mass of neutrinos and establishing how quantum mechanics fits with Einsteins theory of relativity.

I believe strongly that this exciting new research programme will enable the UK to take the lead in a new way of exploring profound questions in fundamental physics.

Wormholes may be lurking in the universe and new studies are proposing ways of finding them – The Conversation UK

Posted: at 4:14 pm

Albert Einsteins theory of general relativity profoundly changed our thinking about fundamental concepts in physics, such as space and time. But it also left us with some deep mysteries. One was black holes, which were only unequivocally detected over the past few years. Another was wormholes bridges connecting different points in spacetime, in theory providing shortcuts for space travellers.

Wormholes are still in the realm of the imagination. But some scientists think we will soon be able to find them, too. Over the past few months, several new studies have suggested intriguing ways forward.

Black holes and wormholes are special types of solutions to Einsteins equations, arising when the structure of spacetime is strongly bent by gravity. For example, when matter is extremely dense, the fabric of spacetime can become so curved that not even light can escape. This is a black hole.

As the theory allows the fabric of spacetime to be stretched and bent, one can imagine all sorts of possible configurations. In 1935, Einstein and physicist Nathan Rosen described how two sheets of spacetime can be joined together, creating a bridge between two universes. This is one kind of wormhole and since then many others have been imagined.

Some wormholes may be traversable, meaning humans may be able to travel through them. For that though, they would need to be sufficiently large and kept open against the force of gravity, which tries to close them. To push spacetime outward in this way would require huge amounts of negative energy.

Sounds like sci-fi? We know that negative energy exists, small amounts have already been produced in the lab. We also know that negative energy is behind the universes accelerated expansion. So nature may have found a way to make wormholes.

How can we ever prove that wormholes exist? In a new paper, published in the Monthly Notices of the Royal Society, Russian astronomers suggest they may exist at the centre of some very bright galaxies, and propose some observations to find them. This is based on what would happen if matter coming out of one side of the wormhole collided with matter that was falling in. The calculations show that the crash would result in a spectacular display of gamma rays that we could try to observe with telescopes.

This radiation could be the key to differentiating between a wormhole and a black hole, previously assumed to be indistinguishable from the outside. But black holes should produce fewer gamma rays and eject them in a jet, while radiation produced via a wormhole would be confined to a giant sphere. Although the kind of wormhole considered in this study is traversable, it would not make for a pleasant trip. Because it would be so close to the centre of an active galaxy, the high temperatures would burn everything to a crisp. But this wouldnt be the case for all wormholes, such as those further from the galactic centre.

The idea that galaxies can harbour wormholes at their centres is not new. Take the case of the supermassive black hole at the heart of the Milky Way. This was discovered by painstakingly tracking of the orbits of the stars near the black hole, a major achievement which was awarded the Nobel Prize in Physics in 2020. But one recent paper has suggested this gravitational pull may instead be caused by a wormhole.

Unlike a black hole, a wormhole may leak some gravity from the objects located on the other side. This spooky gravitational action would add a tiny kick to the motions of stars near the galactic centre. According to this study, the specific effect should be measurable in observations in the near future, once the sensitivity of our instruments gets a little bit more advanced.

Coincidentally, yet another recent study has reported the discovery of some odd radio circles in the sky. These circles are strange because they are enormous and yet not associated with any visible object. For now, they defy any conventional explanation, so wormholes have been advanced as a possible cause.

Wormholes hold a strong grip on our collective imagination. In a way, they are a delightful form of escapism. Unlike black holes which are a bit frightening as they trap everything that ventures in, wormholes may allow us to travel to faraway places faster than the speed of light. They may in fact even be time machines, providing a way to travel backwards as suggested by the late Stephen Hawking in his final book.

Wormholes also crop up in quantum physics, which rules the world of atoms and particles. According to quantum mechanics, particles can pop out of empty space, only to disappear a moment later. This has been seen in countless experiments. And if particles can be created, why not wormholes? Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence. Some of these primordial wormholes may still be around today.

Recent experiments on quantum teleportation a disembodied transfer of quantum information from one location to another have turned out to work in an eerily similar way to two black holes connected through a wormhole. These experiments appear to solve the quantum information paradox, which suggests physical information could permanently disappear in a black hole. But they also reveal a deep connection between the notoriously incompatible theories of quantum physics and gravity with wormholes being relevant to both which may be instrumental in the construction of a theory of everything.

The fact that wormholes play a role in these fascinating developments is unlikely to go unnoticed. We may not have seen them, but they could certainly be out there. They may even help us understand some of the deepest cosmic mysteries, such as whether our universe is the only one.

Surprising Discovery of Unexpected Quantum Behavior in Insulators Suggests Existence of Entirely New Type of Particle – SciTechDaily

Posted: at 4:14 pm

In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed in metals rather than insulators, and its discovery offers new insights into our understanding of the quantum world. The findings also hint at the existence of an entirely new type of quantum particle.

The discovery challenges a long-held distinction between metals and insulators, because in the established quantum theory of materials, insulators were not thought to be able to experience quantum oscillations.

If our interpretations are correct, we are seeing a fundamentally new form of quantum matter, said Sanfeng Wu, assistant professor of physics at Princeton University and the senior author of a recent paper in Nature detailing this new discovery. We are now imagining a wholly new quantum world hidden in insulators. Its possible that we simply missed identifying them over the last several decades.

The observation of quantum oscillations has long been considered a hallmark of the difference between metals and insulators. In metals, electrons are highly mobile, and resistivity the resistance to electrical conduction is weak. Nearly a century ago, researchers observed that a magnetic field, coupled with very low temperatures, can cause electrons to shift from a classical state to a quantum state, causing oscillations in the metals resistivity. In insulators, by contrast, electrons cannot move and the materials have very high resistivity, so quantum oscillations of this sort are not expected to occur, no matter the strength of magnetic field applied.

The discovery was made when the researchers were studying a material called tungsten ditelluride, which they made into a two-dimensional material. They prepared the material by using standard scotch tape to increasingly exfoliate, or shave, the layers down to what is called a monolayer a single atom-thin layer. Thick tungsten ditelluride behaves like a metal. But once it is converted to a monolayer, it becomes a very strong insulator.

This material has a lot of special quantum properties, Wu said.

The researchers then set about measuring the resistivity of the monolayer tungsten ditelluride under magnetic fields. To their surprise, the resistivity of the insulator, despite being quite large, began to oscillate as the magnetic field was increased, indicating the shift into a quantum state. In effect, the material a very strong insulator was exhibiting the most remarkable quantum property of a metal.

This came as a complete surprise, Wu said. We asked ourselves, Whats going on here? We dont fully understand it yet.

Wu noted that there are no current theories to explain this phenomenon.

Nonetheless, Wu and his colleagues have put forward a provocative hypothesis a form of quantum matter that is neutrally charged. Because of very strong interactions, the electrons are organizing themselves to produce this new kind of quantum matter, Wu said.

But it is ultimately no longer the electrons that are oscillating, said Wu. Instead, the researchers believe that new particles, which they have dubbed neutral fermions, are born out of these strongly interacting electrons and are responsible for creating this highly remarkable quantum effect.

Fermions are a category of quantum particles that include electrons. In quantum materials, charged fermions can be negatively charged electrons or positively charged holes that are responsible for the electrical conduction. Namely, if the material is an electrical insulator, these charged fermions cant move freely. However, particles that are neutral that is, neither negatively nor positively charged are theoretically possible to be present and mobile in an insulator.

Our experimental results conflict with all existing theories based on charged fermions, said Pengjie Wang, co-first author on the paper and postdoctoral research associate, but could be explained in the presence of charge-neutral fermions.

The Princeton team plans further investigation into the quantum properties of tungsten ditelluride. They are particularly interested in discovering whether their hypothesis about the existence of a new quantum particle is valid.

This is only the starting point, Wu said. If were correct, future researchers will find other insulators with this surprising quantum property.

Despite the newness of the research and the tentative interpretation of the results, Wu speculated about how this phenomenon could be put to practical use.

Its possible that neutral fermions could be used in the future for encoding information that would be useful in quantum computing, he said. In the meantime, though, were still in the very early stages of understanding quantum phenomena like this, so fundamental discoveries have to be made.
