New discoveries help explore the function of regulatory T cells in autoimmune disease and in cancer

More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.

Bats carry SARS like virus

An international consortium headed by CAS researchers has identified that the Chinese horseshoe bat is healthy carriers of a virus that is very closely related to those causing SARS (severe acute respiratory syndrome).

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.

Most comprehensive picture to date of how influenza viruses evolve and are transmitted

In the first large-scale effort of its kind, researchers have determined the full genetic sequence of more than 200 distinct strains of human influenza virus.

Math1 gene plays a pivotal role in the formation of many of the neurons important in hearing and balance

Close your eyes and imagine you are in a darkened Carnegie Hall. Although it's pitch black, you know you are getting closer to the stage as the music gets louder. If you have been there before, you have a sense of the location of the seats and aisles.

Influenza evolution in action

On the eve of the 2005-06 flu season, scientists at The Institute for Genomic Research (TIGR) have captured influenza evolution in action. In a study published in this week's journal Nature, the researchers report the first large-scale project to sequence the influenza virus.

Body's own defenses may cause HIV-related dementia

Publishing in the Sept. 2005 issue of the Journal of Virology, the researchers show that HIV in the temporal lobe mutates at a rate 100 times faster than in other parts of the body, triggering white blood cells to continually swarm to attack the infection. The associated overcrowding and inflammation appear to cause the dementia.

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.

New treatment option for chronic sinusitis

Acclarent on Saturday unveiled their new treatment option for chronic sinusitis, the Balloon Sinuplasty procedure. Results from the initial safety and feasibility study of this unique, catheter-based treatment for chronic sinusitis were presented by William Bolger, MD, FACS.

Set of simple "rules" that nature appears to use to design proteins

By examining how proteins have evolved, UT Southwestern Medical Center researchers have discovered a set of simple "rules" that nature appears to use to design proteins, rules the scientists have now employed to create artificial proteins that look and function just like their natural counterparts.

How the vertebrate eye, as we know it, has emerged over evolutionary time

The evolution of complex and physiologically remarkable structures such as the vertebrate eye has long been a focus of intrigue and theorizing by biologists.

Delicate balance of induction and inhibition in determining tooth cusps

One of the remaining challenges for evolutionary developmental studies of mammals, whose evolution is best known from their teeth, is how their tooth shape is altered during development.

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.

Human brain still evolving, who knows what the future has to offer!

According to a team of University of Chicago scientists they have found strong evidence that the human brain is still evolving.

Percutaneous aortic valve replacement - evolutionary and promising interventional cardiology procedure

Percutaneous aortic valve replacement is becoming a reality and brings new hope for a number of patients who cannot currently be treated with traditional surgical techniques.

Gene B-myb essential in preventing tumors

A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors.

Genome of mammals is much more complex than previously thought

More than 100 scientists from Australia, Asia, Europe and the US have been probing the genome of the mouse in a joint study lasting several years.

New understanding of how our genome works to produce a complex organism like a human being

A series of discoveries by an international consortium of scientists, including a team from The University of Queensland's Institute for Molecular Bioscience (IMB), will transform our understanding of how our genome works to produce a complex organism like a human being.

Overall genome landscape between chimps and humans can be attributed to large segmental duplications

A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome.
