Some like it hot: Worms at deep-sea vents favor a fiery 45-55C

...ous study of desert fire ants, all died within one minute of exposure to a temperature of 55 degrees Celsius. Such ants will survive brief forays into similarly hot areas to obtain food, but do not choose to remain in superheated environs as Alvinellids do. "We speculate that these worms have evolved to pre...

Separate genetic mutations gave people, chimps bitter-taste sensitivity

...ren are asked to taste a piece of paper containing minute concentrations of PTC, they fed plain apples and apples soaked in small concentrations of PTC to the chimps. (PTC is not harmful and the chimps suffered no ill effects from eating it.) These results verified the same gene is responsible for the abili...

'Dead zone' summer killed billions of ocean state mussels

...ered how the loss of so many mussels, which filter minute algae called phytoplankton from the water, might affect the bay's ecosystem. So Altieri calculated the filtering capacity of mussels in the reefs, before and after the hypoxic event. They found that the healthy mussels could filter the equivalent of ...

Building a hand-held lab-on-a-chip to simplify blood tests

...vides accurate appraisals of blood chemistry using minute blood samples. The process takes about two minutes. "Analysis of blood composition is how doctors test for infections and deficiencies in the immune system, monitor health and make medical diagnoses," said Dr. Yu-Chong Tai, investigator on NSBRI's T...

Salk scientist Ron Evans wins 2006 Gairdner Award for his discovery of hormone sensors

...til Dr. Evans' discovery, they had no idea how the minute amounts of hormones produced by the body actually triggered the changes. Because nuclear receptors wield such physiological power, their discovery provided a multitude of targets for clinical scientists to develop new, more effective, and safer drugs...

Book on avian hybrids gives startling new insights into birds' breeding habits

...n wood warblers," said McCarthy. "He thought for a minute and said 'maybe two.' In fact, there are 70 listed in my book, almost all of them occurring in a natural setting. The realization that even people who are otherwise well informed about birds are often largely unaware that bird hybrids are common was ...

Value of services performed by insects tops $57 billion in US

...'t let the insects' small stature fool you - these minute marvels provide valuable services." The study found that native insects are food for wildlife that supports a $50 billion recreation industry, provide more than $4.5 billion in pest control, pollinate $3 billion in crops and clean up grazing lands, w...

New male contraceptive clears hurdle

"RISUG would be exciting because it would mean that, finally, I could take control of my own future, instead of lea...

The unseen impact - could adult diseases be caused by food and chemicals before birth?

...uals but we've got to look beyond this to identify minute changes that are outside what's 'normal'. The sheer numbers involved in this study and the fact that the samples come from many different countries will increase this variability and make it bigger than anything we've tackled before." But this comple...

Missing breast cancer genes may soon be discovered

..., UK was created in 2004 to provide free up to the minute genetic data to scientific communities and to prevent the duplication of research. The data in COSMIC has expanded to include data on 538 genes, 124,367 tumours with 23,157 mutations. So far in genetic research 350 cancer genes have been identified ...

Cold case: Looking for life on Mars

...ur studies showed that we can detect even the most minute amounts of the element nitrogen, which can be evidence of life. Interestingly, rocks might be particularly promising places to find traces left by the tiniest microbes. Svalbard is brittle cold, very dry, and rocky, much like the Martian environment,...

Some heart patients vulnerable to mental stress

...electrocardiographic measurements were taken every minute during the speech and for 10 minutes afterward. About half an hour after the speech, participants underwent heart imaging scans that reflected blood flow to the heart during the stressful situation. "These are patients who for example might have had ...

Anthrax spores may survive water treatment

...viable spores. "Under those same conditions, one minute exposure could kill 99.99 percent of other waterborne pathogens that do not exist as spores," says Calomiris. Higher concentrations of chlorine were much more effective. At 5mg/L (a concentration that might be used by treatment systems during perio...

Born with a love of speech

..., one or the other sound type was played for a one minute interval. The infants were observed for changes in their sucking behaviour. "The neonates changed their behaviour to elicit speech," says Dr. Vouloumanos. "What we found is that their sucking behaviour increased to hear speech and it decreased when t...
