Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. But why is it that there are such differences in autumnal hues around the world? A new theory [...]

A new look at a large database of prostate cancer patients shows that obesity plays no favorites when it comes to increasing the risk of recurrence after surgery. Being way overweight is equally bad for blacks and whites, say researchers.
Researchers have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae. The findings may further reveal the environmental and health dangers of carbon nanoparticles.

The labeling information that comes with prescription drugs tells you what’s known about the medication, but several researchers think it’s high time that the labeling tell you what isn’t known.
In an advance toward the first portable device for detecting human bodies buried in disasters and at crime scenes, scientists are reporting early results from a project to establish the chemical fingerprint of death. The study could also lead to an electronic device that could determine the time elapsed since death quickly, accurately and onsite.
The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease, stem from a genetic mutation that causes the incorrect substitution of a single amino acid in the chain of thousands of amino acids making up a collagen molecule, the basic building block of bone and tendon.
