Multiple sclerosis -- antihypertensive drug ameliorate inflammation in the brain
Researchers in Heidelberg and Stanford have discovered a new signalling pathway of brain cells that explains how widely used antihypertensive drugs could keep inflammation in multiple sclerosis (MS) in check.

MicroRNAs play a role in cocaine addiction
MicroRNAs, already linked to cancer, heart disease and mental disorders such as schizophrenia, may also be involved in addiction. A team of Rockefeller University neuroscientists has shown that a protein that plays a crucial role in the regulation of microRNAs, short stretches of RNA that silence genes, is also involved in regulating the motivation to consume cocaine. The findings, published online July 19 in the Journal of Experimental Medicine, have already led to the identification of several microRNAs in mice that likely play a role in drug addiction and the scientists say the work could ultimately lead to new ways of combating addictive diseases in humans.

Why fad diets work well for some, but not others
Ever notice some people seem to eat anything they want and never gain a pound, while others seem to gain weight just by looking at fattening foods? You may be seeing things correctly after all. According to research published in the July 2010 issue of Genetics, this may have a biological cause. Using fruit flies, researchers have found that genes interacting with diet, rather than diet alone, are the main cause of variation in metabolic traits, such as body weight. This helps explain why some diets work better for some people than others, and suggests that future diets should be tailored to an individual's genes rather than to physical appearance.

A man with attitude
Heterosexual women bear the brunt of narcissistic heterosexual men's hostility, while heterosexual men, gay men and lesbian women provoke a softer reaction, according to psychologist Dr. Scott Keiller from Kent State University at Tuscarawas in the US. This is likely to be due to women's unparalleled potential for gratifying, or frustrating, men's narcissism. They are crucial players and even gatekeepers in men's quests for sexual pleasure, patriarchal power and status. Dr. Keiller's findings are published online in Springer's journal Sex Roles.

Electronic cigarettes require more suction than conventional brands
Stronger suction is required to smoke "electronic cigarettes" - marketed as tobacco-free nicotine delivery systems - than conventional brands, with possible adverse effects on human health, researchers at the University of California, Riverside report.

Protein found to control the early migration of neurons
Long before a baby can flash her first smile, sprout a first tooth or speak a first word, the neurons that will form her central nervous system must take their first, crucial steps. And these steps must be careful to take the right neurons to the right places and avert developmental disasters that could thwart those other baby firsts from ever coming to pass. Now new research promises a deeper understanding of how this essential form of cell migration occurs, finding a gene that works behind the scenes to control a closely related adhesion gene that helps keep young neurons on the right track.

Electrical activity in developing brain influences choice of neurotransmitter
Cascades of genetic signals determine which neurotransmitter a brain cell will ultimately use to communicate with other cells. Now a pair of reports from biologists at the University of California, San Diego, have shown for the first time that electrical activity in these developing neurons can alter their chemical fate—and change an animal's behavior—by tweaking this genetic program.

Implanted glucose sensor works for more than one year, could aid diabetes patients
Bioengineers developed an implantable glucose sensor and wireless telemetry system that continuously monitors tissue glucose and transmits the information to an external receiver. The paper, to be published in the July 28, 2010 issue of the journal Science Translational Medicine, describes the use of this glucose-sensing device as an implant in animals for over one year. After human clinical trials and FDA approval, the device may be useful to people with diabetes as an alternative to finger sticking and short-term, needle-like glucose sensors that have to be replaced every 3 to 7 days.

Aging and longevity tied to specific brain region in mice
Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.

Molecular mechanism triggering Parkinson's disease identified
Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.

Microbes on the menu
The functioning of marine ecosystems depends on the size and flavor of microbes at the base of the food chain. Changes to the Earth's atmosphere might rearrange that microscopic menu. Microbes that currently are the main course for other organisms might get harder to find in the future, and microbes that are now inconspicuous as members of a "rare biosphere" might become more common.

When flowers turn up the heat
Could a "hot" flower attract pollinators by serving as a reward in a plant-pollinator mutualism? Many flowering plants produce nectar and pollen as rewards in exchange for pollination services by insects and other animals. Interestingly, however, a few plants have flowers that also produce heat metabolically -- so what is the adaptive function of this flower heating?

Researchers have found that an enzyme in the bacteria that causes cholera uses a previously unknown mechanism in providing the bacteria with energy. Because the enzyme is not found in most other organisms, including humans, the finding offers insights into how drugs might be created to kill the bacteria without harming humans.

Ancient DNA identifies donkey ancestors, people who domesticated them
Genetic investigators say the partnership between people and the ancestors of today's donkeys was sealed not by monarchs trying to establish kingdoms, but by mobile, pastoral people who had to recruit animals to help them survive the harsh Saharan landscape in northern Africa more than 5,000 years ago.
