Climate models disagree on why temperature 'wiggles' occur

A new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. The models also provide inconsistent explanations of why this variability occurs...

Ads effective even in the midst of multitasking, studies find

Brittany Duff and co-author Sela Sar found that video ads viewed while multitasking were just as effective as when viewed alone, at least for those who process content more holistically. They also found that multitasking probably works best when you're in a good mood.Those video ads playing in the corner of your computer screen, in the midst of your multitasking, may have more impact than you realize. They may be as effective as...

Many women with breast cancer have poor knowledge about their condition

A new analysis has found that many women with breast cancer lack knowledge about their illness, with minority patients less likely than white patients to know and report accurate information...

Engineering self-assembling amyloid fibers

Amyloid fibers self-assemble from smaller proteins. UC Davis researchers have engineered other proteins so they spontaneously form amyloid. These new proteins could be useful in nanotechnology. Here, the cap structure (red) was removed from spruce budworm antifreeze protein and other structures adjusted so that molecules could link up as fibrils (bottom).Nature has many examples of self-assembly, and bioengineers are interested in copying or manipulating these systems to create useful new materials or devices. Amyloid proteins, for example, can self-assemble into...

Study finds rabies booster defends pets with out-of-date vaccination against the disease

A new study by Kansas State University veterinary diagnosticians finds that pets with out-of-date rabies vaccinations are very unlikely to develop the fatal disease if given a rabies booster immediately...

Entanglement on a chip: Breakthrough promises secure communications and faster computers

Drawing of the silicon ring resonator with its access waveguide. The green wave at the input represents the laser pump, the red and blue wavepackets at the output represent the generated photon pairs, and the infinity symbol linking the two outputs indicates the entanglement between the pair of photons.Unlike Bilbo's magic ring, which entangles human hearts, engineers have created a new micro-ring that entangles individual particles of light, an important first step in a whole host of new...

Researchers identify brain circuit that regulates thirst

Howard Hughes Medical Institute researchers have identified the brain circuit that regulates thirst.Howard Hughes Medical Institute scientists have identified a circuit in the brains of mice that regulates thirst. When a subset of cells in the circuit is switched on, mice immediately...

Pro-marijuana 'tweets' are sky-high on Twitter

Patricia A. Cavazos-Rehg, Ph.D., and her Washington University research team found there were 15 times as many pro-pot tweets as anti-pot tweets during one month they tracked Twitter. Most sending and receiving these tweets were teens and young adults, a group at elevated risk for marijuana dependence and drug-related problems.Analyzing every marijuana-related Twitter message sent during a one-month period in early 2014, researchers at Washington University School of Medicine in St. Louis have found that the "Twitterverse" is a...

Climate affects the development of human speech

This map shows the distribution of languages with complex tone (red dots) and without complex tone (blue dots) in the Phonotactics Database of the Australian National University. Darker shading on map corresponds
to lower mean specific humidity.An interesting question, one that linguists have long debated, is whether climate and geography affect language. The challenge has been to untangle the factors that cause sounds to change.

Calculating the future of solar-fuel refineries

A team of University of Wisconsin-Madison engineers has developed a new tool to help plot the future of solar fuels.

H.E.S.S. finds three extremely luminous gamma-ray sources

Wits scientists are part of a multinational team of astronomers working on the High Energy Stereoscopic System (H.E.S.S.) telescopes that have again demonstrated its excellent capabilities in searching for high-energy...

Researchers at Penn, UC Berkeley and Illinois use oxides to flip graphene conductivity

Graphene, a one-atom thick lattice of carbon atoms, is often touted as a revolutionary material that will take the place of silicon at the heart of electronics. The unmatched speed at which it can move electrons, plus its essentially two-dimensional...

High cholesterol in 30s, 40s, increases later risk of heart disease

UCI, fellow chemists find a way to unboil eggs

UC Irvine and Australian chemists have figured out how to unboil egg whites -- an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of...

UGA researchers image and measure tubulin transport in cilia

Julie Craft is a sixth-year doctoral student at the University of Georgia and is studying the mechanism behind tubulin transport and its assembly into cilia.Defective cilia can lead to a host of diseases and conditions in the human body--from rare, inherited bone malformations to blindness, male infertility, kidney disease and obesity. Scientists knew that...

Gigantic ring system around J1407b much larger, heavier than Saturn's

Artist's conception of the extrasolar ring system circling the young giant planet or brown dwarf J1407b is shown. The rings are shown eclipsing the young sun-like star J1407, as they would have appeared in early 2007. The best fit model is consistent with a system of at least 30 rings, and there are gaps where satellites ("exomoons") may have already formed.Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is...

Largest-ever autism genome study finds most siblings have different autism-risk genes

The largest-ever autism genome study, funded by Autism Speaks, reveals that the disorder's genetic underpinnings are even more complex than previously thought: Most siblings who have autism spectrum disorder (ASD)...

Study shows Brazil's Soy Moratorium still needed to preserve Amazon

Soybeans grow near a forested area in the Brazilian state of Mato Grosso. Under the Soy Moratorium, major trading companies do not purchase soybeans produced in the Brazilian Amazon on recently deforested areas.Today, fewer chicken nuggets can trace their roots to cleared Amazon rain forest.
