Neural bottleneck found that thwarts multi-tasking

A steady, high-fat diet is bad, but the news gets worse

...rstand how the mechanisms work. "Telling people to never eat something is probably not a good way to promote a better diet," he says. "At the same time we do have an epidemic of obesity in North America and it’s important that people try to make informed choices." ...

Prehistoric mystery organism verified as giant fungus

...ant fungus, but agonized over the fact that he was never able to find a smoking gun in the form of reproductive structures that would convince the world that it was indeed a fungus," Hotton said. Co-authoring the Geology paper with Boyce, Hotton and Hueber himself were Marilyn Fogel, George Cody and Rob...

Natural polyester makes new sutures stronger, safer

...sed on MIT research, patients who get stitches may never need to have them removed. A biopolymer suture cleared last month by the FDA is made of materials that the human body produces naturally, so they can be safely absorbed once the wound is healed. They are also 30 percent stronger than sutures now use...

E. coli bacteria migrating between humans, chimps in Ugandan park

...ion of Uganda, Goldberg said, but antibiotics have never been used in local wildlife, so the antibiotic-resistant bacteria in chimps clearly originated in humans. Goldberg said it was not clear whether the exchange of bacteria was the result of direct or indirect (environmental) association between the ...

Ocean's 'twilight zone' may be a key to understanding climate change

...meters below the surface. Because the carbon often never reaches the deep ocean, where it can be stored and prevented from re-entering the atmosphere as a green-house gas, the oceans may have little impact on changes in the atmosphere or climate. The research is the result of two international expeditions...

Fish can determine their social rank by observation alone, study finds

...d E. Researchers made sure that the bystander had never met any of his five potential rivals. Although the bystander remained alone in his cubicle and never swam with the others, he was allowed to observe a series of fights between rival pairs--A vs. B, B v...

Reactivated gene shrinks tumors

...ed that p53 would kill normal cells because it had never been expressed in those cells. "This means you can design drugs that restore p53 and you don't have to worry too much about toxic side effects," said Ventura. Possible therapeutic approaches to turn on p53 in human cancer cells include small mo...

Minuscule molecules pack a powerful punch

...itute. "Although plentiful, this class of gene had never before been knocked out in mice, the best model for human disease. "But we simply did not know whether microRNA knockouts would have an effect in mice: previous knockout studies in nematode worms suggested that most microRNAs were not essential. ...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...rus, the disease progression is slow and they may never develop cirrhosis, even after decades of infection. The dilemma physicians face, explained Cheung, is deciding who to treat and who can wait for better therapies to come along. The key is being able to determine which patients are likely to see...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

"A re-think is needed now that we know where flood plumes go," says CSIRO scientist Arnold Dekker, "and what this means as organic micropollutants may be travelli...

New fMRI technology making brain tumor surgery safer

... University Hospital and UC. Neurosurgeons have never simply guessed at where critical areas of the brain begin and end. First and foremost, they are trained to understand the fundamentals of the brain’s anatomy. But boundaries are not always clear, and the growth of a tumor can cause functional areas t...

ASU researchers test antibacterial effects of healing clays

It is these avenues, at the boundaries of scientific discovery, at the edges of my field and knowledge (and Shelley's), where such discoveries are made." National Institutes of Health (NIH) program directors agreed. They aw...

Unique gene regulation gives chilly bugs survival advantage at bottom of the world

The larvae of Antarctic midges never stop producing special proteins that minimize environmental stress, allowing them to withstand a range of intense environmental conditions in one of the world's harshest environments. Scientists found that adult midges (Belgica antarctica) lose the...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

... the course of the work, we saw something that had never been noticed before?additional protein density beneath the matching nucleotide,?Kornberg said. The team traced that protein density back to a portion of the polymerase II enzyme: the trigger loop. “Of the 14 crystal structures now reported in whi...

Vanishing beetle horns have surprise function

... hornless Onthophagus adults (usually the females) never form the horns in the first place. They do, the scientists say, but the nubile horn tissue is reabsorbed before the beetles' emergence as adults. "The formation of horns by beetle pupas that soon lose them just doesn't seem to make sense, so obvi...
