Fatty fish protects against cancer

...onth would be one good way to go about it. At the end of the 1980s, 90,000 Swedish women were sent a questionnaire on their dietary habits in connection with their mammography scan. Now, with the help of another questionnaire a decade later and the cancer registry, scientists at Karolinska Institutet ha...

It is plentiful in stem cells where it keeps the telomeres long, allowing the cells to keep dividing without limit which is n...

Before transit they will be cleaned of all trace of the marine life they have housed on Merseyside ?just as they were cleaned when they arrived in Crosby fro...

A giant among minnows: Giant danio can keep growing

...he two species were the same size at hatch. By the end of week one, the giant danio was significantly larger and remained so. This result was not surprising, since the giant danio is so much larger at adulthood, about twice as large. But the study was the first to report the early larval growth of these ...

Steep oxygen decline halted first land colonization by Earth's sea creatures

... notes that atmospheric oxygen rose sharply at the end of the Silurian period about 415 million years ago, to reach a level of about 22 percent of the atmosphere, similar to today's oxygen content. But 55 million years later, atmospheric oxygen levels sank to 10 percent to 13 percent. The level remained ...
