Virginia Tech crashed the supercomputing arena in 2003 with System X, a machine that placed the university among the world's top computational research facilities. Now comes HokieSpeed, a new supercomputer that is up to 22 times faster and yet a quarter of the size of X, boasting a single-precision peak of 455 teraflops, or 455 trillion operations per second, and a double-precision peak of 240 teraflops, or 240 trillion operations per second. That's enough computational capability to place HokieSpeed at No. 96 on the most recent Top500 List (http://www.top500.org/), ...

Most people have the best of intentions when it comes to their New Years resolutions. As the year comes to an end, it is only natural to reflect on what we have accomplished and what we still want to change. This is actually what generates the desire within to make the changes needed to get to where we want to be. Whether it is to lose weight, find a significant other, or excel in the workplace for most people this true desire for change does exist. So what happens? Why do so many men and women with good intentions and true desire fall short of their New Years resolutions ...

Scientists have uncovered how nature minimises energy costs in rings of liquids with an internal nanostructure made of two chemically discordant polymers joined with strong bonds, or di-blocks, deposited on a silicon surface, in an article about to be published in EPJE¹. Josh McGraw and his colleagues from McMaster University, Canada, and the University of Reading, UK, first created rings of di-block polymers that they liken to building doughnuts from Lego blocks due to the nature of the material used. This material has an internal structure discretised like Lego blocks, ...

In this struggling economy many child support obligors have lost their jobs or have faced a reduction in income. This may qualify for a modification of their child support order. John Griffith, a Del Mar, California divorce attorney, commented on a recent court ruling involving the modification of child or spousal support. "Non-custodial parents may not realize that support orders don't adjust just because their situation has altered," said Griffith, who's also a child custody lawyer. "A motion to modify your support order should be filed as soon as ...

CAMBRIDGE, Mass. - We've all heard it: The Internet has flattened the world, allowing social networks to spring up overnight, independent of geography or socioeconomic status. Who needs face time with the people around you when you can email, text or tweet to and from almost anywhere in the world? Twitter, the social networking and microblogging site, is said to have more than 300 million users worldwide who follow, forward and respond to each other's 140-character tweets about anything and everything, 24/7. But MIT researchers who studied the growth of the newly hatched ...

AUGUSTA, Ga. – A brain cell type found where habits are formed and movement is controlled has receptors that work like computer processors to translate regular activities into habits, researchers report. "Habits, for better or worse, basically define who we are," said Dr. Joe Z. Tsien, Co-Director of the Brain & Behavior Discovery Institute at Georgia Health Sciences University. Habits also provide mental freedom and flexibility by enabling many activities to be on autopilot while the brain focuses on more urgent matters, he said. Research published in the journal Neuron ...

Bacteria living in people's large intestine may slow down the activity of the "good" kind of fat tissue, a special fat that quickly burns calories and may help prevent obesity, scientists are reporting in a new study. The discovery, published in ACS' Journal of Proteome Research, could shed light on ways to prevent obesity and promote weight loss, including possible microbial and pharmaceutical approaches, the authors said. Sandrine P. Claus, Jeremy K. Nicholson and colleagues explain that trillions of bacteria live in the large intestine of healthy people, where they ...

In a discovery that may help speed use of "cell therapy" — with normal cells or stem cells infused into the body to treat disease — scientists are reporting development of a way to deliver therapeutic human cells to diseased areas within the body using a simple magnetic effect. Their report appears in ACS' journal Langmuir. Rawil Fakhrullin and colleagues explain that cell therapy aims to replace damaged or diseased cells in the human body with normal cells or stem cells. To do so, medical personnel need a way to target these cells to diseased organs or tissues. So-called ...

WASHINGTON -- The latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series discusses the discovery that household washing machines seem to be a major source of so-called "microplastic" pollution -- bits of polyester and acrylic smaller than the head of a pin -- that researchers now have detected on ocean shorelines worldwide. In the podcast, Mark Anthony Browne, Ph.D., explains that the accumulation of microplastic debris in marine environments has raised health and safety concerns. The bits of plastic ...

Recently, the accuracy of current methods of pain assessment in babies have been called into question. New research from London-area hospitals and the University of Oxford measures brain activity in infants to better understand their pain response. As every parent knows, interpreting what a baby is feeling is often incredibly difficult. Currently, pain in infants is assessed using the premature infant pain profile (PIPP), which is based on behavioral and physiological body reactions, such as crying and facial expression. Though this is a useful measure, it is largely ...

An advance in sensor design* by researchers at the National Institute of Standards and Technology (NIST) and the University of Waterloo's Institute of Quantum Computing (IQC) could unshackle a powerful, yet high-maintenance technique for exploring materials. The achievement could expand the technique—called neutron interferometry—from a test of quantum mechanics to a tool for industry as well. [Watch a short YoutTube video on this work at http://youtu.be/A21iXn2NL-8 ] Neutron beams can be used in dozens of ways to probe complex molecules and other advanced materials, ...

Cancer cells are essentially immortal. The acquisition of an unlimited capacity to divide – the process of immortalization - is a central event in the genesis of tumors. Normally, cells are subject to stringent mechanisms which control their proliferation. Together these ensure that pre-malignant cells are induced to enter a senescent, non-dividing state or to undergo apoptosis, i.e. commit suicide. A research team led by Professor Heiko Hermeking and Dr. Antje Menssen from LMU's Institute of Pathology has now discovered how the regulatory protein c-MYC subverts these controls, ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype device capable of absolute measurements of optical power delivered through an optical fiber. The device is the world's first fiber-coupled cryogenic radiometer that links optical fiber power measurements directly to fundamental electrical units and national standards. It uses a microscopic forest of carbon nanotubes—the world's darkest material—to measure values that are about one-thousandth of the levels typically attained with a cryogenic radiometer lacking direct ...

COLUMBUS, Ohio – A new study published in the journal Nature Cell Biology has discovered how normal cells in tumors can fuel tumor growth. Led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard ...

A new draft computer security publication from the National Institute of Standards and Technology (NIST) provides guidance for vendors and security professionals as they work to protect personal computers as they start up. The first software that runs when a computer is turned on is the "Basic Input/Output System" (BIOS). This fundamental system software initializes the hardware before the operating system starts. Since it works at such a low level, before other security protections are in place, unauthorized changes—malicious or accidental—to the BIOS can cause a significant ...

Ironically, despite excessive caloric intake, many obese women are deficient in vitamins vital to a healthy pregnancy. This and other startling statistics abound when obesity and pregnancy collide. Together, they present a unique set of challenges that women and their doctors must tackle in order to achieve the best possible outcome for mom and baby. In the December issue of the journal Seminars in Perinatology, maternal fetal medicine expert Loralei L. Thornburg, M.D., reviews many of the pregnancy-related changes and obstacles obese women may face before giving birth. ...

ANN ARBOR, Mich. -- New research from the University of Michigan suggests obesity can be seen as one of the unintended side effects of free market policies. A study of 26 wealthy nations shows that countries with a higher density of fast food restaurants per capita had much higher obesity rates compared to countries with a lower density of fast food restaurants per capita. "It's not by chance that countries with the highest obesity rates and fast food restaurants are those in the forefront of market liberalization, such as the United States, the United Kingdom, Australia, ...
