Computer model shows biochemical variations, or noise, leads to oscillations in gene regulation that couldn't otherwise be predicted

Geneticists have debated for decades the relative importance of nature versus nurture in determining how an animal looks and behaves, and now University of California, San Diego (UCSD) scientists report that noise could also be an important factor in determining phenotype.

Rise in oxygen content corresponds exactly to a really rapid rise of large, placental mammals

The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet, according to Paul Falkowski, Rutgers professor of marine science and lead author of a paper published Sept. 30 in the journal Science.

The immune mechanisms of atherosclerosis

Scientists are depicting a novel scheme for atherosclerosis development, suggesting that this pathology might result from an imbalance between pro-inflammatory processes and calming ones.

Clostridium botulinum exposed

A discovery by Institute of Food Research (IFR) scientists is set to improve the food industry’s ability to predict foodborne botulism.

Seaweed extract, alginate, could be used to increase the fibre content of junk food

The highly-fibrous seaweed extract, alginate, could be used to increase the fibre content of cakes, burgers and other types of food which usually contain large amounts of fat and a low degree of healthy nutrients, say the team.

New method to measure circadian cycles

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation.

Deep-sea sponges harbor toxins that potentially can act as powerful anti-cancer drugs

Vibrantly colored creatures from the depths of the South Pacific Ocean harbor toxins that potentially can act as powerful anti-cancer drugs, according to research findings from University of Wisconsin-Madison biochemists and their Italian colleagues.

Scientists identifiy new type of pain-sensing neuron in rats

We all know that if you put your hand over an open flame it's very painful. What you may not know is that, for some people, just lying under a blanket is painful as well. They have neuropathic pain--annoying, chronic pain that comes from a diseased nerve cell rather than a specific stimulus. Feeling phantom pain in a missing limb is another, more famous, example.

Scientists eventually may be able to determine the structure of proteins from their genomic sequences

Computers can predict the detailed structure of small proteins nearly as well as experimental methods, at least some of the time, according to new studies by Howard Hughes Medical Institute researchers.

"Designer" rats help show how declining estrogen after menopause can affect hypertension

Scientists at Wake Forest University School of Medicine have created a better research rat – the first to enable them to study how declining estrogen after menopause can affect hypertension, heart failure and kidney damage.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

Simple organism can produce 10 trillion varieties of a single protein

A team led by University of California, San Diego biochemists has discovered the mechanism by which a simple organism can produce 10 trillion varieties of a single protein, a finding that provides a new tool to develop novel drugs.

Antibiotic resistance has put humans in an escalating 'arms race' with infectious bacteria

...as scientists try to develop new antibiotics faster than the bacteria can evolve new resistance strategies. But now, researchers have a new strategy that may give them a leg up in the race -- reproducing in the lab the natural evolution of the bacterial enzymes that confer resistance.

Prions rapidly 'remodel' good protein into bad

Two Brown Medical School biologists have figured out the fate of healthy protein when it comes in contact with the infectious prion form in yeast: The protein converts to the prion form, rendering it infectious. In an instant, good protein goes bad.

Scientists have discovered a new and potent anti-cancer compound in beans

Scientists have discovered a new and potent anti-cancer compound in everyday food. The collaborative study led by UCL (University College London) shows that the compound - inositol pentakisphosphate - found in beans, nuts and cereals inhibits a key enzyme (phosphoinositide 3-kinase) involved in tumour growth.

Finding may significantly broaden understanding of how the brain selects and retains information

By examining how sounds are registered during the process of learning, UC Irvine neurobiologists have discovered a neural coding mechanism that the brain relies upon to register the intensity of memories based on the importance of the experience.

Discovery of mechanism linking color vision and cancer genes

Biologists at New York University have discovered a system by which a random choice between two distinct cellular fates in the fruit fly eye becomes firmly established.

Key to stem cell transplant success is tricking immune system

Tricking the body's immune system into ignoring stem cells will be the key to successful stem cell transplants, according to Professor Maggie Dallman, Imperial College London, speaking this week at the BA Festival of Science.

Transplantation of organs from animals to humans could soon be a reality

Speaking at the BA Festival of Science in Dublin, Dr Anthony Warrens, discussed how xenotransplantation, the process of transplanting organs from one species into another, could soon be a reality, easing the current shortage of organs for transplantation.
