'Exercise pill' switches on gene that tells cells to burn fat

...f muscles, since muscles like to be exercised, and increase the burning of energy or excess fat in the body. And that would result in less fatty tissue, lower amounts of fat circulating in the blood, lower blood glucose levels and less resistance to insulin, lowering the risks of heart disease and diabetes. ...

Does evolution select for faster evolvers?

...hy the speed and complexity of evolution appear to increase with time. For example, the fossil record indicates that single-celled life first appeared about 3.5 billion years ago, and it then took about 2.5 billion more years for multi-cellular life to evolve. That leaves just a billion years or so for the ev...

Unique tomatoes tops in disease-fighting antioxidants

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

... near-shore migrations. With an average population increase of about eight percent per year, the east coast cownose ray population may now number as many as 40 million. The rays, which can grow to be more than four feet across, eat large quantities of bivalves, including bay scallops, oysters, soft-shell and ...

Investment level in HIV prevention programs related to HIV incidence in the United States

...ict incidence. That is, as the nation continued to increase the funding of HIV prevention programs, HIV dropped substantially from 160,000 infections per year to about 40,000 infections per year. In the early 1990s, as the level of investment (adjusted for inflation) flattened out with little annual change, s...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

...echniques developed by Gu, the researchers hope to increase the number probes they can fit on a chip. "Right now, we have a mechanical printing technology that could put down billions of probes on a chip surface at very low cost," said Gu. It is estimated that a single base pair can be sequenced for eve...

Salmonella survives better in stomach due to altered DNA

Since 1995 there has been a considerable increase in the number of infections with a specific type o... genetic information might also be involved in the increase in the number of infections caused by this pathogen. By comparing the DNA of Salmonella serovar Ty...

Stress hormones may play new role in speeding up cancer growth

... hormones produced as during periods of stress may increase the growth rate of a particularly nasty kind of cancer. The study showed that an increase in norepinephrine, a stress hormone, can stimulate tumor cells to produce two compounds. These compo...

St. Jude announces breakthrough in eye cancer treatment

...d less-toxic treatment," Dyer said. "It could also increase the chance that their vision can be preserved by eliminating the tumor and preventing its spread from the eye to the rest of the body." The discovery that blocking MDMX releases the apoptosis response in retinoblastoma has important implications f...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

Researchers have used a single compound to increase the lifespan of obese mice, and found that the dru...or the last 70 years, scientists have been able to increase the lifespan of a variety of species by reducing their normal food consumption by 30 to 40 percent -...

Low levels of neurotransmitter serotonin may perpetuate child abuse across generations

... research suggests that treatments with drugs that increase brain serotonin early in an abused child's life could reduce the likelihood that the child will grow up to become abusive, Maestripieri said. Maestripieri is lead author of a paper reporting the research, "Early Maternal Rejection Affects the Devel...

By 2048 all current fish, seafood species projected to collapse

"The good news is that it is not too late to turn things around," Worm said. The scientists studied 48 areas worldwide tha...

Key to zebrafish heart regeneration uncovered

... "Within days of the injury, we find a significant increase in the expression of certain genes in the epicardial cover," Poss said. "These genes are typically expressed only during embryonic development of the cardiovascular system. The epicardial cells mobilize to cover the wound and blastema, and help provi...

Proteins may predict lung transplant rejection

... new therapies, said Wendt. Doctors may be able to increase the dose of anti-rejection drugs when the early markers of rejection appear. Or, they may reduce anti-rejection drugs for people who do not show early signs of rejection. (Anti-rejection drugs have their own side effects, including an increased chanc...

New study aims to stop sepsis in its tracks

... "The goal of this project is to speed recovery, increase survival rates, and improve the long-term quality of life for those who have had sepsis," said NIGMS Director Jeremy M. Berg, Ph.D. One of the major challenges is to recognize sepsis when it starts. That's because in its early stages, it is often m...

Signal protein shows promise for blocking tumor promoters in skin cells

...ry a gene that codes for Srcasm into skin cells to increase Srcasm production, as used in some other gene therapy treatments. Initially, clinicians may try this method on oral cavity and skin cancers. Next, the Penn researchers will determine whether Srcasm can actually reverse tumor formation in skin. Se...

"Nonoxynol 9 was used commonly and was thought to be an extremely safe type of anti-microbial spermicide. But researchers found that it actually increased the rate of HIV infection in women. So now we real...
