Researchers from Penn State University College of Medicine suggest that a shared circuit in the brain could be one reason why heavy drinking and high-fat 'junk food' cravings go hand in hand.
Amanita phalloides is non-native to the North American continent, introduced to California from Europe, and rapidly spreading.
The study found no long-lasting differences in the DNA of the two Kelly brothers after one year space.
Scientists are banking frozen DNA in the hope of saving endangered animals in the future.
It's not just your imagination — people feel freer to bail out on others at the last minute than they used to. But why?
Surprisingly, sheep semen stored for 50 years produced perfectly healthy lambs.
Horseshoe crabs have blue blood that can detect toxins, a rare ability that's threatening their survival.
