UCSF researchers identify regulator of critical brain messenger, hinting at therapy
... we inhibited one isoform, it wouldn't necessarily undermine
basic glutamate function," says Edwards, "because the other isoform might be able to carry on the day-to-day functions." The discovery of the glutamate transporter rounds out the understanding of the mechanisms by which neurotransmitters are released...
New fossils may be first human ancestors out of Africa, say Science authors
...African cradle. The Dmanisi fossils, however, may undermine
this tale of the technologically triumphant hominid. Stone tools found with the two skulls are of the less sophisticated "pebble-chopper" type that preceded the Acheulean in Africa, and the site itself is older than any known Acheulean tools. The too...

...nything to do with snake origins. The finding does undermine
the theory that Pachyrhachis represents an evolutionary link between marine reptiles and true snakes. Snakes like boas and pythons have a distinctively mobile skull structure that allows them to nearly unhinge their jaw in a formidable gape and "wa...
