A team of researchers has demonstrated that the brain predicts consequences of our eye movements on what we see next. The findings, which appear in the journal Nature Neuroscience, have implications for understanding human attention and applications to robotics. The study was conducted by researchers at University Paris Descartes, New York University's Department of Psychology, and Ludwig-Maximilian University in Munich. Our eyes jump rapidly about three times each second to capture new visual information, and with each jump a new view of the world falls onto the retina—a ...

The federal peer review system, by which research proposals are judged worthy for funding, may be "over stretched" and "susceptible to error," said Elmer Yglesias, a researcher at the Science and Technology Policy Institute and author of "Improving Peer Review in the Federal Government," published in the current issue of TECHNOLOGY & INNOVATION, Proceedings of the National Academy of Inventors ™, (www.academyofinventors.org) now available on-line at: http://www.cognizantcommunication.com/filecabinet/Technology/techinnovation.html According to Yglesias, the federal ...

The number and scale of forest fires has increased dramatically in recent decades. Who can forget last summer's television images of blazing infernos devouring miles and miles of forest in Russia, Australia and California? In Germany, too, several regions are under threat precipitated by climate change – Brandenburg, for example, is one of the areas of Europe that are most at risk. Often, fires can only be contained from the air. In order to fight them in a targeted way, firefighting planes need to be given precise information on where the flames are at their worst. Infrared ...

The so-called "superstreet" traffic design results in significantly faster travel times, and leads to a drastic reduction in automobile collisions and injuries, according to North Carolina State University researchers who have conducted the largest-ever study of superstreets and their impacts. Superstreets are surface roads, not freeways. It is defined as a thoroughfare where the left-hand turns from side streets are re-routed, as is traffic from side streets that needs to cross the thoroughfare. In both instances, drivers are first required to make a right turn and ...

The research has created a diagnostic scoring system that improves on established criteria. Led by Charis Eng, M.D., Ph.D., Chair of the Genomic Medicine Institute at the Lerner Research Institute of Cleveland Clinic, the study – the largest clinical study to date on the identification ...

Since the 50s, formaldehyde has been the basic material for many artificial resins and glues used in particleboards and plywood boards. Estimates indicate that more than 85 percent of all wood materials have adhesives containing formaldehyde. This substance escapes from the materials and, along with other sources, pollutes indoor air. This is why numerous ways have been developed to reduce emissions, and the International Agency for Research on Cancer (IARC) of the World Health Organization WHO has even classified formaldehyde as carcinogenic for humans. Thereupon both ...

A paper describing a dramatic change during the 20th century in England and Wales in the association between social class and mortality from liver cirrhosis features in Alcohol and Alcoholism. While deaths from cirrhosis were more common among higher social classes in the early part of the century, the pattern changed so that deaths from cirrhosis were much more common among the lower social classes by the end of the century. Data on male cirrhosis mortality by social class were obtained from the Registrar General's Decennial Supplements for the years 1921�. The ...

PITTSBURGH, Jan. 10 – A researcher at the University of Pittsburgh School of Medicine, in collaboration with scientists from the National Institutes of Health (NIH), has discovered that the deadly plaques of Alzheimer's disease interact with certain cellular proteins to inhibit normal signals that maintain blood flow to the brain. Their findings, which could lead to new approaches to treat the dementia, were recently published in Public Library of Science One. Levels of nitric oxide (NO) – a signaling molecule that helps regulate blood flow, immune and neurological processes ...

PROVIDENCE, R.I. [Brown University] — The world's oceans are under siege. Conservation biologists regularly note the precipitous decline of key species, such as cod, bluefin tuna, swordfish and sharks. Lose enough of these top-line predators (among other species), and the fear is that the oceanic web of life may collapse. In a new paper in Geology, researchers at Brown University and the University of Washington used a group of marine creatures similar to today's nautilus to examine the collapse of marine ecosystems that coincided with two of the greatest mass extinctions ...

LEXINGTON, Ky. (Jan. 4, 2011) − Scientists at the University of Kentucky have discovered that plasminogen, a protein used by the body to break up blood clots, speeds up the progress of prion diseases such as mad cow disease. This finding makes plasminogen a promising new target for the development of drugs to treat prion diseases in humans and animals, says study senior author Chongsuk Ryou, a researcher at the UK Sanders-Brown Center on Aging and professor of microbiology, immunology and molecular genetics in the UK College of Medicine. "I hope that our study ...

Alexandria, VA – Where to next in the search for oil and gas? EARTH examines several possible new frontiers - including the Arctic, the Falkland Islands, the Levant, Trinidad and Tobago and Sudan - where oil and gas exploration are starting to take hold. One of those places, Sudan, is in the news for other reasons: South Sudan voted yesterday on whether to secede from North Sudan. But given that South Sudan holds more than 70 percent of Sudan's 5 billion to 6 billion barrels of proven reserves, a lot in this election hinges on oil. If South Sudan does secede, how will ...

PITTSBURGH—Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks. Like Facebook, these neuronal networks have a small population of highly active members who give and receive more information than the majority of other members, says Alison Barth, associate professor of biological sciences at Carnegie Mellon and a member of the Center for the Neural Basis of Cognition (CNBC). By identifying these neurons, scientists will now be able to study them further ...

CHAMPAIGN, Ill. – Firms that outsource aspects of their business to a foreign country may profit by saving money, but the practice tends to soften the competition among industry rivals, exacting a hidden cost on consumers, says new research co-written by a University of Illinois business administration professor. Yunchuan "Frank" Liu says outsourcing hurts society in two ways – it results in lost jobs for workers, and in consumers paying higher prices than they should for goods. "Outsourcing is a topic that affects just about everyone, and the general consensus is that ...

The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances. An important characteristic of porphyrins is their conformational flexibility. Recent research has shown that each specific geometric configuration ...

Instances of cyber bullying continue to make news nearly every day, and while it's recognized as a problem among most school-aged children, a new study published this month in Children & Schools and coauthored by Temple University social work professor Jonathan Singer finds that nearly half of school social workers feel they are ill equipped to handle it. "School social workers provide more crisis intervention services than any other school staff member – more than counselors, nurses, teachers, or psychologists," said Singer. "As a result, school social workers are a ...

Comprising the pistons are droplets of nanoparticle-infused ferrofluids, which can... Click here for more information. Troy, N.Y. – A few unassuming drops of liquid locked in a very precise game of "follow the leader" could one day be found in mobile phone cameras, medical imaging equipment, implantable drug delivery devices, ...

Researchers at Nationwide Children's Hospital report a gene therapy strategy that improves the condition of a mouse model of an inherited blood disorder, Beta Thalassemia. The gene correction involves using unfertilized eggs from afflicted mice to produce a batch of embryonic stem cell lines. Some of these stem cell lines do not inherit the disease gene and can thus be used for transplantation-based treatments of the same mice. Findings could hold promise for a new treatment strategy for autosomal dominant diseases like certain forms of Beta Thalassemia, tuberous sclerosis ...

Using biological samples taken from patients and state-of-the-art biochemical techniques, a Florida State University researcher is working to identify a variety of "biomarkers" that might provide earlier warnings of the presence of breast and prostate cancers. "Biomarkers are indicators of certain biological and pathological processes that are occurring, such as cancer," said Qing-Xiang "Amy" Sang, a professor in Florida State's Department of Chemistry and Biochemistry. "Either the cancer cells themselves, or surrounding normal tissue for that matter, can produce specific ...

UCLA researchers have found that a protein that plays an important role in some antioxidant therapies may not be as effective due to additional mechanisms that cause it to promote atherosclerosis, or clogging of the arteries. Published in the January issue of the journal Arteriosclerosis, Thrombosis and Vascular Biology, the finding may give clues as to why some antioxidant therapies have not yielded more positive results. The protein, called Nrf2, has been thought to be an important drug-therapy target for diseases such as cancer because it can induce chemopreventive ...

Persistence paid off for a University of Alberta paleontology researcher, who after months of pondering the origins of a fossilized jaw bone, finally identified it as a new species of pterosaur, a flying reptile that lived 70 million years ago. Victoria Arbour says she was stumped when the small piece of jaw bone was first pulled out of of a fossil storage cabinet in the U of A's paleontology department. "It could have been from a dinosaur, a fish or a marine reptile," said Arbour. " Arbour, a PhD student in paleontology, says the first clue to the fossil's identify ...

Glass stronger and tougher than steel? A new type of damage-tolerant metallic glass, demonstrating a strength and toughness beyond that of any known material, has been developed and tested by a collaboration of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab)and the California Institute of Technology. What's more, even better versions of this new glass may be on the way. "These results mark the first use of a new strategy for metallic glass fabrication and we believe we can use it to make glass that will be even ...

Washington, D.C. — Sophisticated tools allow scientists to subject the basic elements of matter to conditions drastic enough to modify their behavior. By doing this, they can expand our understanding of matter. A research team including three Carnegie scientists was able to demonstrate surprising properties of the element lithium under intense pressure and low temperatures. Their results were published Jan. 9 on the Nature Physics website. Lithium is the first metal in the periodic table and is the least dense solid element at room temperature. It is most commonly known ...
