Same mutation aided evolution in many fish species, Stanford study finds

...ind fin in body armor. Although it's not clear why losing the armor is a benefit to freshwater fish, Kingsley noted that the unarmored fish are lighter and faster than their more burdened marine cousins. In an effort to learn more about how the armor trait evolves so quickly, Kingsley and his colleagues se...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...es grow and recede like a tree waving in the wind, losing the occasional twig. Over time, the network of branches stabilized into the mature form. "We're looking at a dynamic process that nobody has ever seen before," Smith said. Understanding how neurons mature into their adult role goes beyond zebra fis...

Biodiversity hotspots identify conservation priorities

...the new book. "We must now act decisively to avoid losing these irreplaceable storehouses of Earth's life forms." Nearly 400 specialists contributed to the four-year-long hotspots reappraisal. Their analysis has resulted in an increase in the number of hotspots from 25 to 34. The East Melanesian Islands Ho...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

...n many places where families once lived in fear of losing their children to measles, they're now protected by an effective and inexpensive vaccine," said Carol Bellamy, Executive Director of UNICEF. "What clearer proof could there be of the value of investing in immunization?" The dramatic decline in measl...

...on for 2006, it added. UNICEF said polio has been losing its grip even on the exporting "reservoirs of transmission" -- northern Nigeria, northern India and Pakistan, with India reporting only 14 cases so far this year, all of them polio Type 1, and Pakistan six cases, while Nigeria had found no cases acro...

Scientists discover global pattern of big fish diversity in open oceans

...ere is real cause for alarm here." Scientists say losing the variety of fish does not bode well for the future health of open oceans. A robust portfolio of different species is a key to maintaining our supply of fish in the long term and the ability of these living resources to rebound from environmental c...

Scripps research scientists identify infertility molecule

...hun, Ye, and their colleagues went on to show that losing LPA receptors affected prostaglandin levels. Prostaglandin is a fatty acid found in mammals that is essential for normal implantation. Manipulating parts of LPA signaling may thus be a way of changing prostaglandin levels. This is a significant find...

Genetic discovery could lead to drought-resistant plants

...ep their mouths "shut" longer than usual, to avoid losing gases and water through evaporation. However, they must open their stomata at some point, both to pick up carbon dioxide needed for photosynthesis and to release oxygen back into the atmosphere. This new information will be important to plant breeder...

"There is a lot of research still to be done, but we hope that it will not take more than a few years for this to become a practicable option for women, such as young cancer patients, who would otherwise be left infertile after the...

Exercise aside, genes may ultimately dictate seniors' mobility
