Intermittent, low-carbohydrate diets more successful than standard dieting, study finds Posted: 08 Dec 2011 03:46 PM PST An intermittent, low-carbohydrate diet was superior to a standard, daily calorie-restricted diet for reducing weight and lowering blood levels of insulin, a cancer-promoting hormone, according to recent findings.

Premature babies harbor fewer, but more dangerous microbe types Posted: 08 Dec 2011 02:36 PM PST One of the most comprehensive studies to date of the microbes that are found in extremely low-birthweight infants found that hard-to-treat Candida fungus is often present, as well as some harmful bacteria and parasites.

Nighttime images help track disease from the sky Posted: 08 Dec 2011 11:53 AM PST Satellite images of nighttime lights normally used to spot where people live can help keep tabs on the diseases festering among them, too.

Helping your fellow rat: Rodents show empathy-driven behavior, evidence suggests Posted: 08 Dec 2011 11:19 AM PST The first evidence of empathy-driven helping behavior in rodents has been observed in laboratory rats that repeatedly free companions from a restraint, according to a new study by University of Chicago neuroscientists. The observation, published today in Science, places the origin of pro-social helping behavior earlier in the evolutionary tree than previously thought.

Breakthrough in regulating fat metabolism Posted: 08 Dec 2011 09:57 AM PST Scientists have made an important discovery about the mechanism controlling the body's 'fat switch', shedding new light on our understanding of how proteins regulate appetite control and insulin secretion.

Scientists capture single cancer molecules at work Posted: 08 Dec 2011 09:57 AM PST Researchers have revealed how a molecule called telomerase contributes to the control of the integrity of our genetic code, and when it is involved in the deregulation of the code, its important role in the development of cancer. Scientists explained how they were able to achieve their discovery by using cutting edge microscopy techniques to visualize telomerase molecules in real time in living cells.

Neuroscientists boost memory in mice using genetics and a new memory-enhancing drug Posted: 08 Dec 2011 09:57 AM PST When the activity of a molecule that is normally elevated during viral infections is inhibited in the brain, mice learn and remember better, researchers report.

How Salmonella forms evil twins to evade the body's defenses Posted: 08 Dec 2011 06:27 AM PST To swim or not? The same biological control that determines which capability genetically identical Salmonella will have impacts the virulence of the food pathogen. Swimmers do better in the gut, but non-motile Salmonella avoid triggering killer cells. An unusual protein turns on or off the manufacture of swimming apparatus in each new bacterium.

Combination of everolimus and exemestane improves survival for women with metastatic breast cancer, results show Posted: 07 Dec 2011 05:17 PM PST In an international Phase III randomized study, everolimus, when combined with the hormonal therapy exemestane, has been shown to dramatically improve progression-free survival, according to research.

'Brain tsunamis' are clue to helping victims of major head injuries Posted: 07 Dec 2011 08:35 AM PST Treating 'brain tsunamis' or 'killer waves' could stop many victims of major head injury from suffering additional brain damage, a study has found. Scientists have been investigating this phenomenon for decades, with the topic of spreading depolarizations now of keen interest to the U.S. military because head injuries have emerged as the signature wound of the wars in Iraq and Afghanistan.

Mother's touch may protect against drug cravings later Posted: 06 Dec 2011 09:08 PM PST An attentive, nurturing mother may be able to help her children better resist the temptations of drug use later in life, according to a study in rats conducted by researchers in the United States and Australia.

Addressing pain and disease on the fly: How fruit flies can teach us about curing chronic pain and halting mosquito-borne diseases Posted: 06 Dec 2011 12:15 PM PST Studies of a protein that fruit flies use to sense heat and chemicals may someday provide solutions to human pain and the control of disease-spreading mosquitoes. Researchers have discovered how fruit flies distinguish the warmth of a summer day from the pungency of wasabi by using TRPA1, a protein whose human relative is critical for pain and inflammation.
