Cosmopolitan Lifestyle could allay cancer threat

If the cancer-inhibiting properties of red wine don't tempt you, why not try a cosmopolitan, the cranberry-based cocktail made famous by the Sex and the City girls.

Cannabis boosts brain power in rats

Scientists now say that Cannabis, the third most popular recreational drug after alcohol and tobacco, could boost brain power.

Alternative methods to create stem cells successful in mice-studies

According to researchers in the U.S. two alternative methods for making embryonic stem cells, work in mice and could lead to a less controversial way to grow them.

Nanobombs to eradicate cancer

University of Delaware researchers are opening a new front in the war on cancer, bringing to bear new nanotechnologies for cancer detection and treatment and introducing a unique nanobomb that can literally blow up breast cancer tumors.

Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.

Technique for inserting genes into specific sites on the genome in liver cells

The genes are inserted into non-coding regions of the genome so there is no danger of interfering with the functioning of other genes. Once inserted, the gene remains a permanent part of the cell's genome.

Scientist shed light on bizarre reproductive conflicts encountered by hermaphroditic animals

By directly manipulating mating performance in a tropical sea slug, Chelidonura hirundinina, researchers of the University of Tubingen have now shed light on the bizarre reproductive conflicts encountered by hermaphroditic animals. In some hermaphroditic species, such as C. hirundinina, mating partners may insist on copulating as a "male," "female," or both, resulting in unique biological conflicts over gender.

Researchers find gene that is important for the control of fundamental rhythms in nematode worms

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping.

New technique to produce large numbers of antibodies quickly

Faster method to create antibodies for disease research British scientists are pioneering a new technique to produce large numbers of antibodies quickly and reliably to help the study of dangerous bacteria.

Discovery of new features of a key quality-control mechanism in our cells

Mutations in genes are the basis of evolution, so we owe our existence to them. Most mutations are harmful, however, because they cause cells to build defective proteins. So cells have evolved quality control mechanisms that recognize and counteract genetic mistakes.

Scientists genetically modify male mosquitoes to express a glowing protein in their gonads - may help control the mosquito population

By providing a way to quickly sex mosquitoes, the advance paves the way for pooling large numbers of sterile males which could be used to control the mosquito population.

Tissue engineering used to reconstruct defective tracheas (windpipes) in fetal lambs

Researchers at Children's Hospital Boston report using tissue engineering to reconstruct defective tracheas (windpipes) in fetal lambs, first using cells from the amniotic fluid to grow sections of cartilage tube, and then implanting these living grafts into the lambs while still in the womb.

Brain needs the middle ear to track depth

When you jaywalk, your ability to keep track of that oncoming truck despite your constantly changing position can be a lifesaver. But scientists do not understand how such constant updating of depth and distance takes place

New role for the blood protein serum amyloid P in the body's response to medical materials

Using a technique called proteomics, the researchers identified many of the blood proteins that stick (adsorb) to the surfaces of medical devices. Blood proteins that adsorb to the surfaces of materials unfold and can be recognized by the body, which then mounts a response against the device.

Immature stem cells that proliferate to form brain tissues in mice can function for at least a year

New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year -- most of the life span of a mouse -- and give rise to multiple types of neural cells, not just neurons.

Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.

Scientists measure with unprecedented accuracy the strengths of hydrogen bonds in a protein

The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.

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.
