Vitamin A's paradoxical role in influencing symmetry during embryonic development revealed

... retinoic acid makes sure that some of those cells ignore the left-right instructions and progress symmetrically. Belmonte compares the node to a doorway. "Before embryonic stem cells enter the node, they don't have an orientation. Nor are they differentiated into specialized tissues -- such as heart or br...

New clue to cocaine addicts' quirky behavior

"Thus, although abnormally induced LTP by psychostimulants at limbic inputs might not interfere with learning a response strategy, it may reduce the capacity of these animals to con...

Discovery suggests why stem cells run through stop signs

... offer one of the first clues as to why stem cells ignore stop signs in the cell cycle: a special molecular mechanism has cut the brakes. The researchers found that tiny bits of genetic material called microRNAs are necessary for stem cell division to take place, suggesting that microRNAs shut off the signa...

Modification of program enables prediction of gene transcription

...nt gene finding systems ?except for N-SCAN ?either ignore the UTR splice sites or incorrectly incorporate them into some protein-coding segment, making gene prediction a none-too-sure industry. "We've found that when we add the spliced untranslated regions to our system, we not only get good predictions fo...

Traditional models underestimate extinction rates

Standard models for predicting extinction assume that population growth and decline are governed by random, or stochastic, variables. But few scientists have actually test...

'Executive' monkeys influenced by other executives, not subordinates

The discovery represents more than a confirmation of what most people believe about their bosses, said the researchers. The findings reve...

Why nerve cells work faster than the theory allows

...ty of the threshold potentials allows the cells to ignore slowly varying stimuli. The cells continuously increase their threshold so that in many cases no impulse is initiated at all. The fast activation of action potentials, on the other hand, helps the cells to transmit fast changing signals, even with hi...

Losing sleep undoes the rejuvenating effects new learning has on the brain

This suggests that learning to ignore stimuli and rapid attention switching are competing processes, with healthy individuals ignoring familiar stimuli as their primary strategy. It would be interesting to assess whether sleep restriction causes people to lose the ability to screen out e...
