Determining the genetic composition of brain cancers informs treatment, predicts outcome

Research confirms that determining the genetic composition of brain cancers can better inform doctors and patients for treatment options and prognosis.

Which inflammatory markers predict the appearance of a stroke?

Patients that have suffered from a stroke have a higher risk of a similar event happening and, in consequence, greater possibilities of dying.

When it comes to honesty the eyes have it!

According to researchers in the UK people behave in a more honest fashion when they think they are being watched.

Structure of bacteriophage shown to resemble a human virus

New research has revealed that the structure of a bacteriophage, a virus infecting bacteria, resembles that of certain dangerous viruses that infect people.

AIDS might be an accident of evolution

The virulence characteristic of HIV-1 - the virus predominantly responsible for human AIDS - might amount to an accident of evolution, new evidence reveals.

Researchers identify new keys to regulation of bacterial gene expression

The cellular process of transcription, in which the enzyme RNA polymerase constructs chains of RNA from information contained in DNA, depends upon previously underappreciated sections of both the DNA promoter region and RNA polymerase

Evidence of RNA in structures essential to cell division

Evidence for the first time that centrosomes, which play a key role in cell division, may carry their own genetic machinery, answering a controversial question of long standing.

Research explains how pathogenic bacteria evolved over millions of years

Bacteria like Salmonella have a complicated immune system that helps them recognize and isolate foreign DNA trying to invade their cell membrane, according to a University of Washington-led study in the June 8 issue of Science Express.

Centrosomes may contain ribonucleic acid

Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes - organelles essential to cell division in humans and animals.

Cigarette smoking and high cholesterol predict different forms of peripheral artery disease

Cigarette smoking and high cholesterol predict risk for some forms of peripheral artery disease (PAD), while diabetes predicts risk for other forms of the disease, researchers reported in a rapid access issue of Circulation: Journal of the American Heart Association.

Two specific genes, Wnt4 and Fgf9 fight to determine sexual differentiation

Whether or not a fertilized mammalian egg ultimately develops into a male or female is determined by the winner of a tug of war between two different genes encoding signaling proteins and the divergent pathways they control.

Scientists gain better understanding of Proteus mirabilis

Scientists now have inside information to use in the fight against Proteus mirabilis - a nasty bacterium that can cause kidney stones, as well as hard-to-treat urinary tract infections.

Scientists map the entire active protein inventory in cells

Scientists have shown how cutting-edge methods can be used to catalogue the entire inventory of active proteins in cell organelles at a particular moment. Their work sheds considerable light on how cells use proteins.

For women a man's face says it all

According to a controversial new study, researchers say men's faces reveal their interest in having children, and women subconsciously pick up these subtle cues when choosing a partner.

An evolutionary life-history framework for understanding sex differences in human mortality rates

Despite research efforts to find modern factors that would explain the different life expectancies of men and women, the gap is actually ancient and universal, according to University of Michigan researchers.

Ancient rodent DNA being used to identify the cause of its low genetic diversity

A rare Patagonian rodent known as the colonial tuco-tuco fascinates biologists because it seems to defy all odds. This threatened species has so little genetic diversity that the slightest whiff of climate change or disease should have wiped it off the face of the earth long ago. Yet the hearty gopher-like creature has not only managed to survive for thousands of years in the harsh climate of the Argentine highlands, it has evolved a complex social structure that's unique among the more than 50 closely related tuco-tuco species.

Discovery of the molecular mechanisms that allow animals to switch genes on or off to gain or lose anatomical characteristics

Anatomical features, scientists know, come and go. The animal kingdom is full of critters that have independently gained or lost similar features. Whales and snakes, for instance, have lost their legs. Winged flight evolved separately in birds, bats and pterosaurs at different times in evolutionary history.
