in animals and has never before been seen in a photosynthetic eukaryote like a diatom, she says. Nitrogen is crucial for diatom growth and is often in short supply in seawater, depending on ocean conditions. The genome work revealed that the diatom T...

small circular DNA fragments in the cells of these patients that contain the ABL1 cancer gene. ABL1 also plays an important role in other forms of leukemia. The good news is that ABL1 is counteracted with the drug Glivec, and so this medication can n...

that over long periods of time, 'gaps', or differences in their life histories, opened up between the evolving parasitoid wasp species, which are not filled by others. They suggest this may explain the great diversity of wasps seen in nature. "There ...

Talented sniffer: A receptor known for guiding sperm to egg plays a role in the nose
Researchers have found
that a human olfactory receptor protein previously shown to act in sperm, where it appears to help guide sperm to the egg during fertilization, is also expressed in human olfactory tissues in the nose and functions in our sense of smell. This remarka...
