Don't stand so close to me: A new view on how species coexist

...because evolution has caused them to compromise on key life measures, say ecologists at Imperial College London and Royal Holloway, University of London, writing in the journal Science today (1 October). The researchers suggest a new basis for explaining how communities of species assemble: they have to ...

Of lice and men

...he analysis of lice genes also confirmed two other key developments in human evolution. First, it verified studies showing how and when various species branched off the family tree of primates and humans. Second, it confirmed the "out of Africa" theory that the population of Homo sapiens mushroomed after...

First, how does the system respond to the thousands of molecules of different shapes and sizes that we call odorants--"does it use a restricted number of promiscuous receptors, or a la...

Talented sniffer: A receptor known for guiding sperm to egg plays a role in the nose

...onally expressed on sperm cells, appears to play a key role in sperm-egg communication and chemotaxis prior to gamete encounter. Whether this "sperm" olfactory receptor is restricted to reproductive functions or acts bi-functionally in the context of conventional olfaction has been a longstanding questio...

Ubiquitin is a protein found within cells that targets other proteins for elimination. Scientists have long known that all cells manufact...

Brain circuit may permit scientists to eavesdrop on memory formation

"First, lesions of the hippocampus prior to training can prevent the formation of some kinds of short-term memory. Second, if one delays the hippocampal lesion to days after training, o...

Biologists ID molecular block for social 'cheaters'

...yostelium without the gene dimA, which codes for a key protein that Dictyostelium cells use to recognize DIF-1. "We wanted to see if cells without dimA could cheat the system by ignoring DIF-1 and thereby increase their chances of becoming spore cells rather than stalk cells," said paper co-author David ...

New genetic tools provide clues to the effects of exercise and diet on obesity, diabetes

... to Hittel, "we found coordinated up-regulation of key metabolic enzymes with aerobic training in metabolic syndrome aspartate aminotransferase 1, lactate dehydrogenase B and pyruvate dehydrogenase alpha 1 subunit. All were also quickly down-regulated by detraining, although the induction wasn't an acute...

Bugs in the gut could play key role in understanding human disease and drug toxicity

"Having these structures now will help us attack that problem, because we know that this bacterial version of SONO is very similar to so...

U-M scientists see ubiquitin-modified proteins in living cells

...that an E3 ligase binding enzyme called Itch was a key player in the process. "Itch is the adapter," Kerppola says. "It tags Jun with ubiquitin, and is necessary for the protein to be targeted to the lysosome." If Itch doesn't recognize Jun, Kerppola explains, the level of Jun builds up in the cel...
