Researchers First to 'See' Reactive Oxygen Species in Vital Enzyme

(PhysOrg.com) -- Using two simultaneous light-based probing techniques at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, a team of researchers has illuminated important details about a class of enzymes involved in everything from photosynthesis to the regulation of biological clocks.

Rare 'dinky' bird migrates to US for first time

(AP) -- Birders with binoculars and cameras are flocking to a remote state park in search of a small yellow-chested bird that apparently crossed the U.S. border for the first time from its high-mountain habitat to the south.

Tests show algae toxin in some sick pelicans

(AP) -- A toxic chemical produced by algae has been detected in some sick California brown pelicans that are being found in record numbers along the West Coast, though researchers don't believe it's the primary cause of their widespread illness, wildlife experts said Friday.

More Effective Treatment For Pneumonia Following Influenza Found, Study Shows

Scientists have demonstrated a more effective treatment for bacterial pneumonia following influenza. They found that the antibiotics clindamycin and azithromycin, which kill bacteria by inhibiting their protein synthesis, are more effective than a standard first-line treatment with the "beta-lactam" antibiotic ampicillin, which causes the bacteria to lyse, or...

'Stroke Belt' Deaths Tied To Non-traditional Risk Factors

A new report underscores the notion that stroke risks go beyond geographic and racial differences. Researchers report that non-traditional risk factors must explain the South's higher stroke death rate. What those factors are need further study, but clearly diabetes and hypertension play an important role, the study authors...

How Bed Bugs Outsmart Poisons Designed To Control Them

Bed bugs, once nearly eradicated in the built environment, have made a big comeback recently, especially in urban centers such as New York City. In the first study to explain the failure to control certain bed bug populations, toxicologists show that some of these nocturnal blood suckers have developed resistance to pyrethroid insecticides, in particular deltamethrin, that attack their nervous...

Large Earthquakes Trigger A Surge In Volcanic Eruptions

New evidence shows that very large earthquakes can trigger an increase in activity at nearby volcanoes. An analysis of records in southern Chile has shown that up to four times as many volcanic eruptions occur during the year following very large earthquakes than in other years. This 'volcanic surge' can affect volcanoes up to at least 500 km away from an earthquake's...

PETA: Spearfish school should be called Sea Kitten (AP)

AP - The activist animal rights group People for the Ethical Treatment of Animals has asked school officials to change the name of Spearfish High School to "Sea Kitten High School." The new name would "reflect the gentle nature of its current marine namesake," the organization said in a letter to Steve Morford, Spearfish High School principal.

Science and ethics of embryo cancer screening is complex

The little girl born free of the BRCA1 gene that so often causes breast cancer is not a designer baby in the strict sense of the phrase. Her parents did not choose her hair colour, or select an aptitude for maths. But the birth breaks new ground because, for the first time, embryo selection was made for the purpose of reducing, not eliminating, the baby's chances of getting breast cancer when she...

Bad science: A detoxer in denial

Obviously by now you can guess my views on detox: meaningless, symbolic, gimmicky, short-lived gestures with a built-in expiry date, when we could be reading about the NHS's surprisingly useful website to help you stop smoking (do it now: smokefree.nhs.uk). I'm not trying to bore you, but after a few months of concentrating on dodgy reporting in the media, I had forgotten how far out a proper...
