A potential biological cause for sudden infant death syndrome

...y will wake up, turn its head, and start breathing faster when carbon dioxide levels rise," explains Kinney. But in babies who die from SIDS, defects in the serotonin system may impair these reflexes, the researchers believe. Kinney previously documented serotonin receptor abnormalities in two other p...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...ss" that heats oil and sugar about a million times faster than you can in your kitchen and produces hydrogen...ng gasoline. The new process works 10 to 100 times faster than current technology, with no input of fossil fuels and in reactors at least 10 times smaller tha...

Osteoarthritis may be sign of faster 'biological ageing'

...rative inflammatory bone disease, may be a sign of faster "biological ageing," suggests research published ahead of print in the Annals of the Rheumatic Diseases. The authors base their findings on a study of almost 1100 people, aged between 30 and 79. Most of them were female twins. X-rays of both hand...

Novel experiment documents evolution of genome in near-real time

...re genomes as a way to find mutations that enabled faster growth. After six days of growth, mutations appe...-called glycerol kinase gene grew 20 to 60 percent faster than those without the mutation. Mutations also appeared in a second, unrelated gene for an enzyme...

Invasive ants territorial when neighbors are not kin

...g territories, then colonies should grow at a much faster rate." In their native Argentina, aggressive interactions between colonies are much more common and colonies are significantly smaller. When Argentine ants were introduced to California 100 years ago, they spread widely because they did not encoun...

German researchers develop first non-invasive test to measure skin aging

...and initial results suggest that women's skin ages faster than men's. Findings appear in the October 1 issue...ex-dependent, with women's skin losing collagen at faster rates than men's. The two methods combined in the imaging technique use the ability of ultra-brie...

Gold nanoparticles prove to be hot stuff

...tion pressure more efficiently, which would enable faster measurements and detection of smaller motions at the same laser power. As described in the Aug. 15 issue of Optics Letters,* the JILA team demonstrated that 100-nanometer-wide gold beads, as expected because of their metallic nature, can be trapped a...

NHGRI aims to make DNA sequencing faster, more cost effective

...nt progress over the last several years to develop faster and more cost-effective sequencing technologies and, we are committed to supporting these innovative efforts to benefit scientific labs and medical clinics," said NHGRI Director Francis S. Collins, M.D., Ph.D. "These technologies will eventually revo...

New clues to how sex evolves

...nding sites on different Pairing Centers makes for faster chromosome pairing and thus faster reproduction -- unlike organisms that need to find a mate before they can reproduce, and mature more...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...less nature but starts to reproduce ?and at a much faster rate than the new influenza virus. This fast reproduction rate ?spurred by the new flu infection ? means that the new invading influenza is effectively crowded out by the 'protecting virus'. This vastly slows the progress of the new infection, prev...

Cities change the songs of birds

...ory defense, the urban songs were shorter and sung faster than the forest songs. The urban songs also showed an upshift in frequency that is consistent with the need to compete with low-frequency environmental noise, such as traffic noise. Anthropogenic Impact on Signals Used by Wild Birds Earlier w...

Train your brain to hear your friends at a party

...ing from the left will reach the left ear slightly faster than it reaches the right ear). This is known as binaural or "spatial" hearing because it helps us identify where a sound is coming from and to concentrate or focus our hearing on that particular sound. But, if you have some form of hearing probl...

Researchers develop technologies to devour food pathogens

...y many types of bacteria, and is about three times faster and one-tenth as expensive as current technology. A second innovation uses chlorine dioxide gas to kill pathogens on produce, fresh fruits and vegetables. This would be a large step up from current technologies, which mainly involve washing and scr...

A new approach to growing heart muscle

...ue was grown using an innovative technique that is faster than others that have been tried in recent years, but still yields tissue with significantly better properties. The approach uses a fibrin gel to support rat cardiac cells temporarily, before the fibrin breaks down as the cells organize into tissue. ...

Engineered yeast speeds ethanol production

... both ethanol and glucose, while producing ethanol faster than un-engineered yeast. The work will be reported in the Dec. 8 issue of Science. Fuels such as E85, which is 85 percent ethanol, are becoming common in states where corn is plentiful; however, their use is mainly confined to the Midwest beca...

Powerful genome ID method extended to humans

...hod to humans, potentially giving cancer biology a faster and more cost-effective tool than traditional DNA sequencing. A student-led group from the laboratory of Michael Waterman, USC University Professor in molecular and computational biology, has developed an algorithm to handle the massive amounts of d...

Longer-lived rodents have lower levels of thyroid hormone

... The study further strengthens the theory that the faster an animal's metabolism, the shorter its life, and vice versa, said Mario Pinto, the study's lead author. The thyroid releases hormones that regulate metabolic rate. "Thyroid hormones are key regulators of metabolism and have been widely implicated...

Taking 'chips' to the next level of gene hunting

...means essentially that all chip experiments become faster and cheaper and can be done on an ever larger scale," says Boeke. The chips his team currently uses cost about $400 per experiment. If the amount of information can be quadrupled, "it would be four experiments for the price of one," he says. Stand...

From managing sugar to managing healing

...s in the dermis, the deeper part of the skin, were faster in rebuilding blood vessels. In follow-up studies of human skin cells in culture, Manuela Martins-Green and colleagues explored the molecular impact of topical insulin on keratinocytes, the cells that regenerate the epidermis after wounding, and on...
