His group...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

..., as well as allow them to escape unharmed if they still become entangled. To create avoidable, detectable, safer gear, the team tinkered with the chemical properties of the ropes. A group of scientists from the Central Institute of Fisheries Technology in India--Dr. M.R. Boopendranath, Dr. P. Pravin, T.R...

Brain-mapping technique aids understanding of sleep, wakefulness

... between time spent awake and time spent asleep is still a big mystery in brain science. By shedding light on the network of neural connections involved in sleep, he said, his and other studies will help unravel the mechanisms involved in sleep homoeostasis. In addition to his laboratory at UT Southwester...

...panded deserts and grasslands, but researchers are still not clear what impact it had on fauna. The Darling Downs contain some of the most extensive and significant Pleistocene megafauna deposits in Australia but because it's been excavated since the 1840s it was assumed that the palaeoenvironment record ...

"This is a very new technology and it requires education both of patients and physicians," Smith says. U-M has cryopreserved eggs for one patient; however,...

Test for early detection of prostate cancer shows promise

...ntify prostate tumors early, while the cancers can still be cured. But PSA testing, like many disease-screening procedures, misses some cases of cancer and in other cases erroneously highlights noncancerous conditions. “This new blood test, when coupled with PSA screening, may help reduce the number of bo...

A puzzle piece found in unraveling the wiring of the brain

...ts when there are fewer than 30,000 human genes is still a scientific mystery. A team headed by Drs. Robin Hiesinger and Hugo J. Bellen at Baylor College of Medicine in Houston have unraveled a piece of that puzzle by finding a gene that plays a key role in brain wiring. A report on their work appears tod...
