...e the lips of the speaker—for example at a crowded cocktail party," he says. "However, currently it is not clear whether and how audio-visual interactions are specialized for the processing of communication signals.

New drug blocks influenza, including bird flu virus

...w agent could be used as part of an anti-influenza cocktail of drugs, much like those used to treat HIV infection. The team hopes to move the research into preclinical phase as quickly as possible. Currently, there are a few effective antiviral medications on the market for influenza, but they are beginnin...

Nanosecond-scale release of stinging jellyfish nematocysts

...efense. These miniature cellular weapons contain a cocktail of hemolytic and neurotoxic poisons, making some cnidarians the most venomous animals known. Injection of the toxins requires an effective release mechanism that breaks the physical barrier of the prey's outer-surface tissue. It was known already tha...

A sweet solution for Alzheimer's disease?

The rats that had received the full cocktail of treatments ?transplanted motor neurons, rolipram, dbcAMP, and GDNF-secreting neural stem cells in the sciatic nerve ?had several hundred transplant-derived axons extending into the peripheral nervous system, more than in any other group. The axons...

Rehydrate -- your RNA needs it

Water molecules trapped in ribozymes can form hydrogen bonds with other water molecules or with parts of the ribozym...

Evolution mystery: Spider venom and bacteria share same toxin

...Arizona. The toxin is uniquely found in the venom cocktail of brown or violin spiders, including the brown recluse, and in some Corynebacteria. The toxin from the spider's venom can kill flesh at the bite site; the bacterium causes various illnesses in farm animals. "Our research was inspired by the fact th...

New possibilities to fight pests with biological means

Corn plants emit a cocktail of scents when they are attacked by certain pests, such as a caterpillar known as the Egyptian cotton leaf worm. Parasitic wasps use these plant scents to localize the caterpillar and deposit their eggs on it, so that their offspring can feed on the...

Scavenger cells could be key to treating HIV-related dementia

...d dementia and others who did not. The well-known cocktail of antiretroviral drugs prescribed to most HIV patients has cut the number of HIV-associated dementia cases reported each year, Gonzalez-Scarano said. However, this is because the drugs slow the progression of the disease, he said. Patients still hav...

Huntington's cure in flies lays groundwork for broader treatment approaches

...ng alternative might be to simultaneously target a cocktail of gene-induced activities - all of which are set in motion, for example, by a single faulty gene. Yin has long worked in the area of "triplet expansion" diseases such as Huntington's and Fragile X, in which genes go haywire due to a coding defect. ...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...rchers' next step will be to develop a quantum dot cocktail capable of simultaneously detecting the presence of at least five major respiratory viruses: influenza A and B, parainfluenza and metapneumovirus, in addition to RSV. This should be fairly straightforward, Wright says. In the current paper, Wright an...

Since they discovered noggin, Harland and his colleagues have shown that in later stages of development, this protein factor is critical ...

Stem cells from brain transformed to produce insulin at Stanford
