Melatonin shrinks bird gonads. What does the popular supplement do in humans?

Berkeley -- Shift workers and travelers who pop melatonin pills to stave off drowsiness or jetlag have another reason to be cautious about taking the supplement, say Japanese and University of California, Berkeley, researchers. A new study shows that melatonin, a hormone available without prescrip...

Neuroscientists locate 'imaginary' colors

...'s as a particular color, the triangle shape would pop out to them from an otherwise black-and-white field. Thanks to their synesthesia, went the thinking behind the task, synesthetes would be able to identify the embedded shapes more quickly than normal controls. Most of the study's synesthetes (five o...

Vampires beware: Scripps scientists describe molecular basis of raw garlic's pungency

...e wrappings. The scent is already strong. Then you pop the clove into your mouth and bite down hard. As you chew the raw garlic, chemicals are released all over your mouth, and when nerve endings in your mouth decorated with TRPA1 and TRPV1 are exposed to the chemicals, the channels open, allow calcium i...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...howed up at the waterhole, O'Connell-Rodwell would pop a tape of the '94 warning call into the deck, and the underground shaker would play it back as a seismic vibration. To make sure the elephants were feeling the calls and not hearing them, microphones were installed above ground so researchers could m...

Immune cells' genetic 'jam session' is controlled by cell division machinery

If a dividing cell's activity is a pop song, then the same process in an immune cell is an extended-play dance remix. The basics of cell division are the same in both, but there's a heck of a lot more going on in immune cells, Johns Hopkins scientists have discovered. All dividing cells h...

International research team announces finished rice genome

...s, similar genes in the other plant species should pop up in roughly the same spots as their rice counterparts. With the finished sequence, rice researchers gain a kind of genetic GPS, while other cereal researchers inherit a hand-drawn map with some important landmarks. TIGR researchers sequenced more...

Flip-flopped chromosome reveals a first clue to Tourette syndrome

Rockefeller researchers discover a biological clock within a clock

... hours that lets the complex explode. The proteins pop apart and roll into the nucleus," Young says. "Somehow, implanted within the system is a timer, formed by Period and Timeless, that counts off six hours. You have a clock within a clock." He notes that this precise timer shows how carefully orchestr...

Gene variation increases SIDS risk in African Americans

... however, the mutant sodium ion channels tended to pop back open, delaying the cells' recovery after a burst of activity. In the heart, changes like this are known to increase the risk for abnormal rhythms and sudden death. Fortunately, a drug called mexiletine, used to treat patients with arrhythmias, ...

Marine mammals are on the frontline of failing ocean health

.... "As old chemicals are taken out of use, new ones pop up," says Krahn. "Often we don't know if the new substitutes will harm the ecosystem." "It's a struggle to find replacements," says O'Hara. "But wouldn't it be better to know ahead of time if certain policies or practices might be disastrous? We co...

A comparative institutional analysis of intellectual property

Biotech innovations pop up every day. From medicines developed by large companies to ingenious solutions worked out by individuals in university labs, new technologies are poised to enter the marketplace. The question is, are patents helping or hurting this process? "Patent...

Cellular scale drug delivery from the inside out

... are inside the target cells, a trigger is used to pop the caps off and release the drug. "We're looking at two levels of control," Lin said of the trigger mechanism. "One level is to have the cell control the release and the other would be to control the release externally." Lin explained that the chem...

Known hydrate deposits hold enough natural gas to supply the world for centuries. One barrier to exploiting this treasure has been difficulty in making gas hydrates in the laboratory t...

Disorderly protein brings order to cell division

...cid Y88. This causes the elbow to change shape and pop out of CDK2's side pocket. The floppy end of p27 carrying T187 is then free to swing up and insert its hand into the pocket of CDK2, where T187 gets tagged by phosphate. "Our study showed that because the floppy part of p27 is so unstructured it can ...

Pills or papayas? Survey finds Americans want healthful foods, not more medicines
