Old and young brains rely on different systems to remember emotional content

DURHAM, N.C.Neuroscientists from Duke University Medical Center have discovered that older people use their brains differently than younger people when it comes to storing memories, particularly those associated with negative emotions. The study, appearing online in the January issue of Psych...

Human genes sing different tunes in different tissues

CAMBRIDGE, Mass. -- Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. Now, an MIT team has shown that this phenomenon, known as alternative splicing, is both far more...

What is wild? Odor attraction among different wildtype Drosophila

Vinegar flies ( Drosophila melanogaster ) show a highly selective behavior towards odor stimuli. A series of behavioral studies showed that a single olfactory stimulus is often not sufficient for immediate attraction to potential food sources or oviposition sites. Interestingly, the behavior diffe...

Ultrasonic frogs can tune their ears to different frequencies

Researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to another. It is the only known example of an animal that can actively select what frequencies it he...

Species have come and gone at different rates than previously believed

Diversity among the ancestors of such marine creatures as clams, sand dollars and lobsters showed only a modest rise beginning 144 million years ago with no clear trend afterwards, according to an international team of researchers. This contradicts previous work showing dramatic increases beginnin...

Extreme nausea and vomiting varies among pregnant women from different countries

Mothers born in India and Sri Lanka are three times more likely to suffer from extreme nausea and vomiting in pregnancy (hyperemesis gravidarum) than ethnic Norwegians. This finding comes from the Norwegian Institute of Public Healths study of 900, 000 first-time pregnancies registered in the Medi...

Concentrating on different aspects of pain leads to breakthrough in migraine genetics

It affects some 15% of the population, including some 41 million people in Europe, and places a considerable burden on healthcare in both the developed and the developing world...

Insects evolved radically different strategy to smell

Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn. In research to be published in the April 13 advance online issue of Nature, researchers a...

Severe asthma may be a different form of the disease

BETHESDA, Md. (Jan. 28, 2008) − A multi-center research project to investigate severe asthma has found a key physiological difference between severe and non-severe forms of the disease, a finding that could help explain why those with severe asthma do not respond well to treatment. The st...

At the root of nutrient limitation, ecosystems are not as different as they seem

TEMPE, Ariz. -- Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are hot-dog limited the extra buns are worthless without h...

Computation to unravel how genes are regulated and shed light on how cells become different

A closer alliance between computational and experimental researchers is needed to make progress towards one of biologys most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression. This emerged from a recent workshop organised by the European Science Foun...

Marine phytoplankton changes form to protect itself from different predators

Suppressing colony formation is a useful strategy against copepods because they prefer to eat colonies of phytoplankton. A tiny single-celled organism that plays a key role in the carbon cycle of cold-water oceans may be a lot smarter than scientists had suspected. In a paper published June 1...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings today at the ASM...

DNA ends: Common tool, different job

Every time a cell repairs or replicates its DNA, the resulting single strand is wrapped up by a dedicated protein complex. In eukaryotes or organisms whose cells have a nucleus, this job is handled by a tripartite complex called replication protein A (RPA). Researchers at the Salk Institute for Bio...

Freeze! Scientists film proteins at work by freezing them at different states

It is difficult to find similarities between Grenoble and Hollywood or between the researchers at the ESRF and the Institut de Biologie Structural (IBS) and world-known filmmakers. However, scientists from these institutes based in Grenoble (France) have managed to produce a movie. The actors are n...

NYU scientists identify how development of different species uses same genes with distinct features

Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features. The findings, which were discovered by researchers in Professor Claude Desplan’s and Steve Small’s labora...

Internal body clock dictates timing of different types of stroke

Their work...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

The continual and inevitable shortening of telomeres, the protective "caps" at the end of all 46 human chromosomes, has been linked to aging and physical decline. Once they are gone, so are we. But there are more ways than one to grow old. Researchers at Salk Institute for Biological Studies demo...

Genetics links whale to two different ocean basins
