Cellular killer also important to memory

"Is it Memory or Is It Death? Caspase-3 and Memory Formation," was his dissertation title. Huesmann has a doctorate in neur...

'Lessons learned' highlighted as global politics of HIV/AIDS examined in new research

...authority and tools; and the consequences of state avoidance or its failure to act for broader society. These themes are addressed across national and social contexts and analytical approaches by the four symposium articles: In "Written in Blood: AIDS Prevention and the Politics of Failure in France" Michae...

Microbes compete with animals for food by making it stink

...ducting laboratory experiments. To eliminate food avoidance because of texture, they fed stone crabs, lesser blue crabs and striped hermit crabs noodle-like test foods made from pureed forms of either the freshly thawed menhaden or the rotten bait. Researchers found that, no matter the rotten bait's texture, ...

Groups and grumps: Study identifies 'sociality' neurons

... in a given species rather than those that provoke avoidance or attack. To test the idea, they conducted two additional experiments. In the first, territorial violet-eared waxbills were exposed to their pair bond partner. As predicted, and in contrast to the response seen after exposure to a bird of the same...

Friendly bacteria in alcoholic milkshake could fight food allergies

...f infants at risk. Currently the only treatment is avoidance of the problematic food. "Friendly" bacteria in kefir may play a role in blocking the pathway involved in allergic responses, Lisa Richards reports in Chemistry & Industry, SCI's fortnightly magazine. Research published today [Monday 16 October 200...

NRC team uses new Quantum Technology to control molecules

...n the A or B products indicated in the figure. The avoidance of light absorption is important because different molecules absorb different colours of light, so it is impossible to find an absorption method that works the same for all molecules. Thus, the new NRC method of 'tilting the hill', based on the Dyna...

Don't care for broccoli? A receptor gene's variation suggests an evolutionary excuse

...dea that evolution of the receptor gene has shaped avoidance of certain vegetables that can inhibit thyroid function. The findings are reported by Mari Hakala and Paul Breslin of Monell Chemical Sciences Center in Philadelphia, Pennsylvania and appear in the September 19th issue of Current Biology, published b...

Psst! Coffee drinkers: Fruit flies have something to tell you about caffeine

...lude that Gr66a is crucial for the normal caffeine avoidance behavior and without it, flies are seemingly indifferent to the bitter taste. The researchers went on to examine whether this indifference to bitter was due to the taste nerves on the fly's "tongue" or some malfunction in the fly's brain. Chemical ...

A new clinical report from the AAP recommends dairy for children with lactose intolerance

... that lactose intolerance should not require total avoidance of dairy foods. In fact, the report cites research indicating that many children who are sensitive to lactose can drink small amounts of milk without discomfort, especially when consumed with other foods. Dairy foods that are often well tolerated in...

Mother deer cannot recognize the calls of their own offspring but sheep and reindeer can

"This appears to be independent of phylogenesis because although fallow deer and reindeer are more closely related than reindeer and sheep, the m...

Researchers discover which organs in Antarctic fish produce antifreeze

Instead, antifreeze glycoproteins (AFGP) originate primarily from the exocrine pancreas and the stomach, say Cheng, Paul A. Cziko and Clive W. Evans in a paper appearing online this week ahead of regular publication in the Pr...

Nilotinib appears to help chronic myelogenous leukemia patients when standard care fails

...patients who are receiving nilotinib, and a strict avoidance of medications that may prolong the QTcF interval," the researchers write in their paper. "We would like to see, in the long run, if there are any unusual side effects to nilotinib, and then directly compare it with Gleevec in newly diagnosed CML pat...

Butterfly speciation event recreated

... order to take advantage of the predator's learned avoidance response (a process known as mimicry). Color patterns also serve as mating cues; these butterflies are extremely choosey about finding mates with their own, species or race-specific, wing pattern. For Heliconius, color is everything.

Researchers look to nature for design inspiration

...ns that stimulate other neurons to give rise to an avoidance behavior, and can also create a memory imprint in the worm's brain. In order to figure out which neurons are activated for a particular behavior, Lu and her team use a laser beam to operate on worm neurons and then study the behavior after the lesion...
