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.

Human Y chromosome stays intact while chimp Y loses genes

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates, new research indicates.

Study suggests cirrhosis and liver disease nearly inevitable for people with hep C

Nearly 80 percent of chronic hepatitis C sufferers who have the disease for several decades will develop cirrhosis or end-stage liver disease later in life, according to a study published today in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology.

Charles Darwin was right and chimp gene map proves it

According to scientists who have mapped the complete chimp genome and compared it to the human gene map, there is little genetic difference between humans and chimps, but those differences count for a lot.

Novel mechanism, called recursive splicing reveals how cells process large genes

Important messages require accurate transmission. Big genes are especially challenging because they combine many coding segments (exons) that lie between long stretches of non-coding elements (introns).

Defects in newly discovered pathway may be an overlooked cause of anemia

Researchers studying zebrafish that die from anemia have discovered a new pathway for the synthesis of heme, the deep red, iron-containing molecule that is a component of hemoglobin and myoglobin.

Faster and more objective way to examine the surfaces of fossilized teeth

Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.

DDT resistance in flies carries no cost

For those concerned with the troublesome effects of genetic resistance to drugs and pesticides, the conventional wisdom of evolution offers a reassuring word: In the absence of the original chemical threat, most resistance mutations would cause a disadvantage to their hosts and might be expected to quickly leave the genetic landscape once the use of a drug or insecticide is suspended or withdrawn.
