The memory of Neil Armstrong lives on at a NASA center.
President Barack Obama on Thursday signed a bill into law that rebrands the Dryden Flight Research Center in Southern California in honor of the late astronaut. Armstrong was a test pilot at the Mojave Desert facility and later became the first moonwalker.
The center is being renamed the NASA Neil A. Armstrong Flight Research Center. As a consolation, the center's test range will be named for Hugh Dryden, a former NASA executive.
It's not the first name makeover for NASA.
In 1999, the Lewis Research Center in Ohio named for George Lewis, the first executive officer of NASA's predecessor agency was changed to the John H. Glenn Research Center, after the first American to orbit Earth.
NASA says it's developing a timeline to carry out the latest name change.

NASA is well-known for its lunar landings and missions to Mars. But the agency makes major use of its space expertise running satellites that monitor the Earth, its climate and its weather.
It currently operates 16 Earth science research missions, and the agency's Earth Science Division is scheduled to launch up to five more in 2014.
Michael Freilich, the scientist who directs the Earth Science Division, took a few minutes to discuss with ClimateWire the importance of the Earth science missions and what he is looking forward to in the new year.
ClimateWire: Why is it important to observe the Earth from space?
Michael Freilich: If you are going to understand the connection between [biological, physical and chemical] processes, you have to be measuring lots of different quantities all at the same time.
The vantage point of space allows us to make measurements that have high spatial resolution but global coverage, and make frequent measurements at a particular place but for long periods of time. We couldn't look at the Earth as an integrated system where you have to measure all these different variables and over all these different scales before the advent of the space age.

NASA Celebrates Mars Rovers' 10-Year Mark Tonight: Watch Live @ 10 pm ET
The Aerospace Safety Advisory Panel (ASAP), an advisory committee that reports to NASA and Congress, has released its 2013 annual report examining NASA's safety performance over the past year and highlighting issues and concerns to agency and government officials.
The report released Wednesday is based on the panel's 2013 fact-finding and quarterly public meetings; "insight" visits and meetings; direct observations of NASA operations and decision-making processes; discussions with NASA management, employees, and contractors; and the panel members' own experience.
"This year's annual report centers on risk, risk management, accountability, and transparency," said panel chairman Joseph W. Dyer. "The panel notes that in pursuit of a U.S. capability to launch humans into space, and in light of constrained budgets, an argument to accept additional risk could be rationally put forward. The ASAP underscores the need to speak transparently about risk and reward. Acceptable risk needs to be formally accepted, made accountable, and explained to the NASA team, Congress, and the public."
The 2013 report highlights:
-- Commercial Crew Program
-- Exploration Systems Development
-- Funding Uncertainty
-- International Space Station (ISS)
-- Technical Authority

NASA's Aerospace Safety Advisory Panel Releases 2013 Annual Report
Climate experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) will announce new data on 2013 global temperatures during a media teleconference at 1:30 p.m. EST Tuesday, Jan. 21.
The scientists also will discuss 2013's most important weather and climate events. NASA and NOAA are two keepers of the world's temperature data and independently produce a record of Earth's surface temperatures and changes based on historical observations over oceans and land.
Consistency between the two independent analyses, as well as analyses produced by other countries, increases confidence in the accuracy of such data, the assessment of the data, and resulting conclusions. These analyses provide government and business leaders with critical information about climate change.
The NASA and NOAA 2013 global temperature analyses will be issued in a news release 90 minutes before the start of the teleconference.
The teleconference panelists are:
-- Gavin Schmidt, deputy director, NASA's Goddard Institute for Space Studies, New York
-- Thomas R. Karl, director, NOAA's National Climatic Data Center, Asheville, N.C. and chair of the Subcommittee on Global Change Research
Media can participate in the teleconference by calling 888-810-6809 (toll-free in U.S./Canada) or 1-212-519-0808 (international) and using the passcode "climate." The briefing also will be streamed live at:

Just give me the FAQ
Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged.
If we rearrange the atoms in coal we can make diamond.
If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips.
If we rearrange the atoms in dirt, water and air we can make potatoes.
Todays manufacturing methods are very crude at the molecular level. Casting, grinding, milling and even lithography move atoms in great thundering statistical herds. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. Yes, you can push the LEGO blocks into great heaps and pile them up, but you can't really snap them together the way you'd like.
In the future, nanotechnology (more specifically, molecular nanotechnology or MNT) will let us take off the boxing gloves. We'll be able to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of nature. This will let us continue the revolution in computer hardware to its ultimate limits: molecular computers made from molecular logic gates connected by molecular wires. This new pollution free manufacturing technology will also let us inexpensively fabricate a cornucopia of new products that are remarkably light, strong, smart, and durable.
"Nanotechnology" has become something of a buzzword and is applied to many products and technologies that are often largely unrelated to molecular nanotechnology. While these broader usages encompass many valuable evolutionary improvements of existing technology, molecular nanotechnology will open up qualitatively new and exponentially expanding opportunities on a historically unprecedented scale. We will use the word "nanotechnology" to mean "molecular nanotechnology".

Jan. 15, 2014 "The interface is the device," Nobel laureate Herbert Kroemer famously observed, referring to the remarkable properties to be found at the junctures where layers of different materials meet. In today's burgeoning world of nanotechnology, the interfaces between layers of metal oxides are becoming increasingly prominent, with applications in such high-tech favorites as spintronics, high-temperature superconductors, ferroelectrics and multiferroics. Realizing the vast potential of these metal oxide interfaces, especially those buried in subsurface layers, will require detailed knowledge of their electronic structure.
A new technique from an international team of researchers working at Berkeley Lab's Advanced Light Source (ALS) promises to deliver the goods. In a study led by Charles Fadley, a physicist who holds joint appointments with Berkeley Lab's Materials Sciences Division and the University of California Davis, where he is a Distinguished Professor of Physics, the team combined two well-established techniques for studying electronic structure in crystalline materials into a new technique that is optimized for examining electronic properties at subsurface interfaces. They call this new technique SWARPES, for Standing Wave Angle-Resolved Photoemission Spectroscopy.
"SWARPES allows us for the first time to selectively study buried interfaces with either soft or hard x-rays," Fadley says. "The technique can be applied to any multilayer prototype device structure in spintronics, strongly correlated/high-TC superconductors, or semiconductor electronics. The only limitations are that the sample has to have a high degree of crystalline order, and has to be grown on a nanoscale multilayer mirror suitable for generating an x-ray standing wave."
As the name indicates, SWARPES combines the use of standing waves of x-rays with ARPES, the technique of choice for studying electronic structure. A standing wave is a vibrational pattern created when two waves of identical wavelength interfere with one another: one is the incident x-ray and the other is the x-ray reflected by a mirror. Interactions between standing waves and core-level electrons reveal much about the properties of each atomic species in a sample. ARPES from the outer valence levels is the long-standing spectroscopic workhorse for the study of electronic structure. X-rays striking a material surface or interface cause the photoemission of electrons at angles and kinetic energies that can be measured to obtain detailed electronic energy levels of the sample. While an extremely powerful tool, ARPES, a soft x-ray technique, is primarily limited to the study of near-surface atoms. It's harder x-ray cousin, HARPES, makes use of more energetic x-rays to effectively probe subsurface interfaces, but the addition of the standing wave capability provides a much desired depth selectivity.
"The standing wave can be moved up and down in a sample simply by rocking the angle of incidence around the Bragg angle of the mirror," says Alexander Gray, a former member of Fadley's UC Davis research group and affiliate with Berkeley Lab's Materials Sciences Division, who is now a postdoctoral associate at Stanford/SLAC. "Observing an interface between a ferromagnetic conductor (lanthanum strontium manganite) and an insulator (strontium titanate), which constitute a magnetic tunnel junction used in spintronic logic circuits, we've shown that changes in the electronic structure can be reliably measured, and that these changes are semi-quantitatively predicted by theory at several levels. Our results point to a much wider use of SWARPES in the future for studying the electronic properties of buried interfaces of many different kinds."
Fadley, Gray and their collaborators carried out their SWARPES tests at ALS Beamline 7.0.1. The Advanced Light Source is a U.S. Department of Energy (DOE) national user facility and Beamline 7.0.1 features a premier endstation for determining the electronic structure of metals, semiconductors and insulators. Additional corroborating measurements concerning the interface atomic structure were performed at the National Center for Electron Microscopy (NCEM), another DOE national user facility hosted at Berkeley Lab.
Results of this study have been published in Europhysics Letters (EPL). The paper is titled "Momentum-resolved electronic structure at a buried interface from soft X-ray standing-wave angle-resolved photoemission." Gray was the lead author, Fadley the corresponding author.
This research was supported primarily by the U.S. Department of Energy (DOE) Office of Science.

Contact: A'ndrea Elyse Messer aem1@psu.edu 814-865-5544 Penn State
Nanotechnology for diagnosing and treating prostate cancer will be the focus of a five-year, $1.58 million grant by the National Institutes of Health to Penn State and the University of Texas Southwestern Medical Center.
Jian Yang, associate professor of biomedical engineering, and Jer-Tsong Hsieh, the Dr. John McConnell Distinguished Chair in Prostate Cancer Research at Texas, will be co-principal investigators.
As part of the effort, Penn State will receive about $651,000.
The research seeks to develop an alternative to chemotherapy, which Yang said causes significant side effects and is also ineffective on many patients who have developed drug resistance to conventional chemotherapy.
The team will aim to create a method to identify a prostate cancer specific drug, a genotoxin to avoid drug resistance. The researchers seek to develop a biodegradable and biocompatible nanoparticle capable of targeting and imaging the prostate cancers.
Yang said he hopes the team's experimental therapy study will lead to a more personalized medical approach to treating prostate cancer.

A lot of patients suffering from colon cancer might well present no symptoms or signs during the earliest stages of the condition. When symptoms do eventually present, they can be many and varied, and can very much depend upon the size of the affliction, how far it has spread and also its actual location. It might be that some symptoms that present are as a result of a condition other than cancer itself, ranging from irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and occasionally diverticulosis. Also, such problems as abdominal pain or swelling can be symptomatic of colon problems and may well require further investigation.
You may also notice that, upon going to the lavatory, you have some blood in your stools, and this can be a symptom of cancer. Of course, having black poop doesnt ultimately mean that cancer is present. It can, however, also be indicative of other conditions and problems. For example, the kind of bright red blood that you may see on your toilet tissue could be as a result of hemorrhoids or anal fissures. It should also be remembered that various food items can also result in red poop, and these include beetroot and red liquorice. Some medications can also be culprits, and some can also turn the stools black-including iron supplements. Irrespective, any sign of blood or change in your stools should prompt you to seek advice from your GP, as it is always best to be sure that it is not a sign of a more serious condition, and with any cancer,early detection and treatment is essential to a successful recovery.
You should also note-if you are currently concerned-any change in the regularity of your stools-including whether or not they are more thin or irregular than usual-especially over a period of several weeks. Also, be mindful if you have diarrhea for several days in a row or, conversely, constipation.
You might also experience pain in your lower abdomen-including a feeling of hardness. You may also experience persistent pain or discomfort in your abdominal region, and this can include wind and cramps. You may also get the sensation that, when evacuating your bowels, that the bowel doesnt empty fully. Another symptom that you might recognize is colored stool mainly black stool, but could be green stool too. Also, if you have an iron deficiency (or anemia), it may be an indication that there is bleeding in your colon. Also, as in most cases and types of cancer, you should seek medical advice immediately if you experience any sudden and unexpected or unexplained weight loss, as this is one of the principal red flags. Also be aware of more vague, seemingly incidental symptoms, such as fatigue. IF you have a couple of symptoms and also feel fatigued for days in a row inexplicably, then this is also another warning sign and you should seek medical advice. It is important not to panic, but just to be aware of what might be going on.
Remember, cases of colon cancer account for around 90% of all cases of intestinal cancers, and also account for more deaths every year of men and women from cancer. Early treatment is an absolute must.
