Nonvenomous Asian snakes 'borrow' defensive poison from toxic toads

Most snakes are born with poisonous bites they use for defense. But what can non-poisonous snakes do to ward off predators? What if they could borrow a dose of poison by eating toxic toads, then recycling the toxins? That's exactly what happens in the relationship be...

Light wine intake is associated with longer life expectancy in men

... the Zutphen Study ?involved a cohort of 1,373 men born between 1900 and 1920 who were surveyed in detail about alcohol consumption seven times over 40 years. The participants, all from Zutphen, an industrial town in the eastern part of the Netherlands, were followed until death or until the final survey...

U of MN researchers turn cord blood into lung cells

...evelopment, which is why some premature babies are born with underdeveloped lungs. The cells and the air sacs as a whole continue to mature and develop through a child's first few years of life. Now the researchers will try to better characterize the cells, so that in the future, the cells could be us...

New study: Preterm birth causes one-third of all infant deaths

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide

...ions, the authors note that virtually all children born in industrialized countries between 1960 and 1980 were exposed to lead from petrol, which may have reduced IQ scores above 130 (considered superior intelligence) by more than half and increased the number of scores less than 70. Today, it's estimated...

Stem cell activity deciphered in the aging brain

In one study, Shetty and colleagues showed that the production of new neurons in rats slows down dramatically by middle age -- the equivalent of 50 years in humans. But scientists did not ...

Embryonic selection of sex avoids conceiving blind children
