How does your brain tell time?

... into a lake," he explained, "the ripples of water produced by the pebble’s impact act like a signature of the pebble’s entry time. The farther the ripples travel the more time has passed. "We propose that a similar process takes place in the brain that allows it to track time," he added. "Every time th...

Stress hormones may play new role in speeding up cancer growth

New research here suggests that hormones produced as during periods of stress may increase the growt...th norepinephrine and, as predicted, the cells all produced MMP-2, MMP-9 and VEGF. This showed that the receptors for this hormone were present on cells in Glas...

Microbes compete with animals for food by making it stink

...m the microbe-laden bait to test whether chemicals produced by the microbes were indeed responsible for these feeding and attraction behaviors. They found that chemical extracts composed of numerous compounds suppressed stone crab feeding when added to otherwise palatable fish flesh. But, of the several sp...

Humanitarians answer Internet challenge So how did a clay mineralogist whose background is in low temperature geochemistry become involved with a health care project centered in the Ivory Coast? The sci...

Global map shows new patterns of extinction risk

...ed world map of mammals, birds and amphibians ever produced shows that endangered species from these groups do not inhabit the same geographical areas, says new research published today. Contrary to conservationists' previous assumptions, the map shows conclusively that geographical areas with a high concen...

Monoclonal antibody reduces exacerbations in asthmatics

...is an intercellular messenger protein, a cytokine, produced by white blood cells. "Anti-TNFá therapy has been shown to be effective in patients with rheumatoid arthritis, ankylosing spondylitis, Crohn's disease and psoriasis, but ineffective in patients with chronic obstructive pulmonary disease (COPD)," sai...

Cloned mice created from fully differentiated cells, a milestone in cloning research

... To the contrary, we found that cloned pups can be produced from adult, fully differentiated somatic cells, a conclusion that goes against popular opinion and current hypotheses," says Dr. Yang, animal science professor, director of the University of Connecticut's Center for Regenerative Biology and co-corres...

Osteoarthritis may be sign of faster 'biological ageing'

... Oxygen free radicals are the unstable molecules produced as a by-product of normal bodily processes, as well as external factors, such as tobacco, alcohol, and sunlight. Osteoarthritis is the most common form of arthritis, with the hands being one of the sites most often affected. Its frequency rises dra...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...s made by plants and animals, but they are usually produced in such small quantities it takes a huge amount of material to characterize them," said Arthur Edison, Ph.D., an associate professor of biochemistry and molecular biology. "In this case, it previously required hundreds of milkings to get enough walki...

Molecular atlas provides new tool for understanding estrogen-fueled breast cancer

...d the word "cistrome" to describe the map they had produced -- an atlas of all gene segments influenced by the ER. "cis" refers to a DNA segment that regulates a gene's activity in response to a signal from outside the gene (while "trans" refers to a factor that acts on DNA); and "ome" -- from the Greek word ...

Why do cold animals make bigger babies?

...at all. Instead, large offspring just happen to be produced by large mothers, who grow large because they require more energy to reproduce in the cold. When they tested the theories simultaneously with their new approach, the team concluded that temperature's effect on reproduction is a byproduct of its ef...

Stem cells engage in dialogue with the cells that regulate their futures

...es help regulate the amount and kinds of new cells produced to meet current demands. The niches also help maintain a supply of stem cells for later use. Inside your body, for example, there are separate niches for stem cells that will become blood, for cells that will become skin, and so on. Niches are pl...

Uncovering DNA's 'sweet' secret

...oxylated six-carbon sugars probably would not have produced a stable base-pairing system capable of carrying genetic information as efficiently as DNA. "The structure now provides insight of a chemical nature that (the six-carbon sugar) is just too 'bulky.' It has too many atoms," Egli said. The new insig...
