(Santa Barbara, Calif.) –– Parasites are ubiquitous. They feed on virtually every animal and even on each other. Yet, for all the parasites' collective contributions to biomass and biodiversity, conventional food webs don't account for the presence of these tiny and numerous consumers. A recent study featuring work by several UC Santa Barbara scientists focuses on the impact parasites have on food webs, with findings that are expected to alter our picture of who-eats-who. The paper, "Parasites Affect Food Web Structure Primarily through Increased Diversity and Complexity," ...

For years, the mantra of neurologists treating stroke victims has been "time equals brain." That's because getting a patient to the emergency room quickly to receive a drug that dissolves the stroke-causing blood clot can make a significant difference in how much brain tissue is saved or lost. But specific information has been limited on just how the timing of giving the intravenous drug — known as a tissue plasminogen activator, or tPA — influences outcomes for victims of ischemic (clot-caused), stroke, the most common type of stroke. Now, a team led by UCLA researchers ...

PORTLAND, Ore. — For years, Alzheimer's researchers have focused on two proteins that accumulate in the brains of people with Alzheimer's and may contribute to the disease: plaques made up of the protein amyloid-beta, and tangles of another protein, called tau. But for the first time, an Alzheimer's researcher has looked closely at not the two proteins independently, but at the interaction of the two proteins with each other — in the brain tissue of post-mortem Alzheimer's patients and in mouse brains with Alzheimer's disease. The research found that the interaction between ...

Researchers at the University of Sydney and Dartmouth College have developed a new way to design quantum memory, bringing quantum computers a step closer to reality. The results will appear June 19 in the journal Nature Communications. Quantum computing may revolutionize information processing, by providing a means to solve problems too complex for traditional computers, with applications in code breaking, materials science and physics. But figuring out how to engineer such a machine, including vital subsystems like quantum memory, remains elusive. In the worldwide ...

In spite of considerable human development, the southeastern United States region could provide some of the Western Hemisphere's more heavily used thoroughfares for mammals, birds and amphibians on their way to cooler environments in a warming world, according to new research led by the University of Washington. The region is among half a dozen areas that could experience heavier traffic compared with the average species-movement across the Western Hemisphere in response to a warming climate. The estimate in southeastern states, for example, is up to 2.5 times the average ...

Kick back and shut your eyes. Now stop thinking. You have just put your brain into what neuroscientists call its resting state. What the brain is doing when an individual is not focused on the outside world has become the focus of considerable research in recent years. One of the potential benefits of these studies could be definitive diagnoses of mental health disorders ranging from bipolar to post-traumatic stress disorders. For the last decade, neuroscientists have been using the non-invasive brain-mapping technique functional called magnetic resonance imaging or ...

Nitrous oxide — best known as laughing gas — is one of the world's oldest and most widely used anesthetics. Despite its popularity, however, experts have questioned its impact on the risk of a heart attack during surgery or soon afterward. But those fears are unfounded, a new study indicates. The findings by researchers at Washington University School of Medicine in St. Louis will appear in the July issue of the journal Anesthesiology. "It's been known for quite a while that laughing gas inactivates vitamin B12 and, by doing so, increases blood levels of the amino acid ...

Oscar Wilde called memory "the diary that we all carry about with us." Now a team of scientists has developed a way to see where and how that diary is written. The team, led by Don Arnold and Richard Roberts of USC, engineered microscopic probes that light up synapses in a living neuron in real time by attaching fluorescent markers onto synaptic proteins – all without affecting the neuron's ability to function. The fluorescent markers allow scientists to see live excitatory and inhibitory synapses for the first time – and, importantly, how they change as new memories ...

August, 2011, saw the dazzling appearance of the closest and brightest Type Ia supernova since Type Ia's were established as "standard candles" for measuring the expansion of the universe. The brilliant visitor, labeled SN 2011fe, was caught by the Palomar Transient Factory less than 12 hours after it exploded in the Pinwheel Galaxy in the Big Dipper. Easy to see through binoculars, 2011fe was soon dubbed the Backyard Supernova. Major astronomical studies from the ground and from space followed close on its heels, recording its luminosity and colors as it rapidly brightened ...

The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits. "There are ways to create these devices with lithography, but it is very hard to create patterns below 50 nanometers using lithography," said Tony Jun Huang, associate professor of engineering science and mechanics, Penn State. "It is rather simple ...

Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Bonn University scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like structure that removes water from leaves and promotes dehydration. These results are published in "Environmental Pollution". Nature conservationists call it "lingering illness", and the latest report on the North-Rhine Westphalian forest conditions confirms ongoing damage. Bonn University ...

COLUMBUS, Ohio – More than 1,500 pedestrians were estimated to be treated in emergency rooms in 2010 for injuries related to using a cell phone while walking, according to a new nationwide study. The number of such injuries has more than doubled since 2005, even though the total number of pedestrian injuries dropped during that time. And researchers believe that the actual number of injured pedestrians is actually much higher than these results suggest. "If current trends continue, I wouldn't be surprised if the number of injuries to pedestrians caused by cell phones ...

EAST LANSING, Mich.-— People who are considered unattractive are more likely to be belittled and bullied in the workplace, according to a first-of-its-kind study led by a Michigan State University business scholar. "Frankly, it's an ugly finding," said Brent Scott, associate professor of management and lead investigator on the study. "Although we like to think we're professional and mature in the workplace, it can be just like high school in many ways." While plenty of research has found that attractive students tend to be more popular in school, the study is the ...

ITHACA, N.Y. – A Cornell University study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes on and off. The study, published June 9 in Nature Genetics, provides evidence for a 40-year-old hypothesis that regulation of genes must play an important role in evolution since there is little difference between humans and chimps in the proteins produced by genes. Indeed, human and chimpanzee proteins are more than 99 percent identical. The ...

The findings are published in the May 28, 2013 edition of Neuroscience Letters. Brian Dranka, Ph.D., postdoctoral fellow at the Medical College of Wisconsin (MCW), is the first author of the paper. Balaraman Kalyanaraman, Ph.D., Harry R. & Angeline E. Quadracci Professor in Parkinson's Research, chairman and professor of biophysics, and director ...

PHILADELPHIA - The motor neuron disease Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, progresses in a stepwise, sequential pattern which can be classified into four distinct stages, report pathologists with the Perelman School of Medicine at the University of Pennsylvania in the Annals of Neurology. This post-mortem staging of ALS brain and spinal cord tissues shows, for the first time, how the fatal degenerative disease may progress from one starting point in the central nervous system to other regions of brain and spinal cord. As evidence mounts ...

This news release is available in German. Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly rhythmic to completely arrhythmic. These differences are attributed ...

ANN ARBOR—Spring floods across the Midwest are expected to contribute to a very large and potentially record-setting 2013 Gulf of Mexico "dead zone," according to a University of Michigan ecologist and colleagues who released their annual forecast today, along with one for the Chesapeake Bay. The Gulf forecast, one of two announced by the National Oceanic and Atmospheric Administration, calls for an oxygen-depleted, or hypoxic, region of between 7,286 and 8,561 square miles, which would place it among the 10 largest on record. The low end of the forecast range is well ...

Crawley, UK-- New data, published today in Menopause International, suggests that post-menopausal women in Britain are experiencing less sex, and less satisfying sex compared to their European and North American counterparts1, because they are considerably less likely to access appropriate treatment for a common, taboo condition called vaginal atrophy1. The first-of-its-kind study, called the CLarifying vaginal atrophy's impact On SEx and Relationships (CLOSER) study, showed that British post-menopausal women with vaginal atrophy are more likely to experience less sex1, ...

In fall 2012, the European Medicines Agency (EMA) approved the modified adeno-associated virus AAV-LPL S447X as the first ever gene therapy for clinical use in the Western world. uniQure, a Dutch biotech company, had developed AAV-LPL S447X for the treatment of a rare inherited metabolic disease called lipoprotein lipase deficiency (LPLD) which affects approximately one or two out of one million people. The disease causes severe, life-threatening inflammations of the pancreas. Afflicted individuals carry a defect in the gene coding for the lipoprotein lipase enzyme which ...

COLUMBUS, Ohio – The ongoing global growth in the human population will inevitably crowd out mammals and birds and has the potential to threaten hundreds of species with extinction within 40 years, new research shows. Scientists at The Ohio State University have determined that the average growing nation should expect at least 3.3 percent more threatened species in the next decade and an increase of 10.8 percent species threatened with extinction by 2050. The United States ranks sixth in the world in the number of new species expected to be threatened by 2050, the research ...

It is likely some of the most widespread and oldest art in the United States. Pieces of rock art dot the Appalachian Mountains, and research by University of Tennessee, Knoxville, anthropology professor Jan Simek finds each engraving or drawing is strategically placed to reveal a cosmological puzzle. Recently, the discoveries of prehistoric rock art have become more common. With these discoveries comes a single giant one—all these drawing and engravings map the prehistoric peoples' cosmological world. The research led by Simek, president emeritus of the UT system and ...

New York, NY, June 19, 2013 – A decade-long JDRF-funded study led by the Institute of Diabetes Research in Helmholtz Zentrum München, Germany, is providing a deeper understanding of the link between autoantibodies and the risk of developing type 1 diabetes (T1D), highlighting the importance of pre-diabetes research into possible preventions for the disease. The study, "Seroconversion to Multiple Islet Autoantibodies and Risk of Progression to Diabetes in Children," was published today in The Journal of the American Medical Association. Researchers in Colorado (DAISY study), ...
