Scientists solve 30-year-old aurora borealis mystery
UCLA space scientists and colleagues have identified the mechanism that triggers substorms in space; wreaks havoc on satellites, power grids and communications systems; and leads to the explosive release of energy that causes the spectacular brightening of the aurora borealis, also known as the northern lights.

The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.

Adult stem cells activated in mammalian brain
Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown.

Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (~redshift 7.5).

Limiting fructose may boost weight loss, researcher reports
One of the reasons people on low-carbohydrate diets may lose weight is that they reduce their intake of fructose, a type of sugar that can be made into body fat quickly, according to a researcher at UT Southwestern Medical Center.

Circadian rhythm-metabolism link discovered
UC Irvine researchers have found a molecular link between circadian rhythms - our own body clock - and metabolism. The discovery reveals new possibilities for the treatment of diabetes, obesity and other related diseases.

Energy Drinks Linked to Risk-Taking Behaviors Among College Students
Over the last decade, energy drinks -- such as Red Bull, Monster and Rockstar -- have become nearly ubiquitous on college campuses. The global market for these types of drinks currently exceeds $3 billion a year and new products are introduced annually.

Scientists break record by finding northernmost hydrothermal vent field
Well inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. The cluster of five vents - one towering nearly four stories in height - are venting water as hot as 570 F.

Region hit hard by 1993 floods showed economic resiliency, study indicates
With the first wave of clean-up efforts behind them, residents of communities affected by this year's Midwest floods may find hope in a University of Illinois study on the economic impact of the 1993 flood that devastated much of the same region.

Researchers identify gene responsible for rare childhood disease
The chromosomal abnormality that causes a rare, but often fatal, disorder that affects infants has been identified by researchers at the University of California, San Diego School of Medicine, who happened to treat two young children with the disease in San Diego - two of perhaps a dozen children in the entire country diagnosed with the disorder.

Accretion Discs Show Their True Colours
Quasars are the brilliant cores of remote galaxies, at the hearts of which lie supermassive black holes that can generate enough power to outshine the Sun a trillion times.

Novel structure proteins could play a role in apoptosis
Isoforms from Novel Structure Proteins (NSP), a new family of genes discovered by researchers in the Sbarro Institute for Cancer Research and Molecular Medicine in Temple University's College of Science and Technology, could be involved in apoptosis or programmed cell death.

A new cellular pathway linked to cancer is identified by NYU researchers
In the life of a cell, the response to DNA damage determines whether the cell is fated to pause and repair itself, commit suicide, or grow uncontrollably, a route leading to cancer.

Early cessation of breastfeeding by HIV+ women in poor countries and child survival
A new study by researchers from Columbia University's Mailman School of Public Health addresses one of the most challenging issues in infant health and preventing mother-to-child HIV transmission in poor countries.

Yale study shows why cigarette smoke makes flu, other viral infections worse
A new study by researchers at Yale School of Medicine could explain why the cold and flu virus symptoms that are often mild and transient in non-smokers can seriously sicken smokers. Published in the Journal of Clinical Investigation, the study also identified the mechanism by which viruses and cigarette smoke interact to increase lung inflammation and damage.

Researchers disprove long-standing belief about HIV treatment
Researchers at Wake Forest University Baptist Medical Center have disproved a long-standing clinical belief that the hepatitis C virus slows or stunts the immune system's ability to restore itself after HIV patients are treated with a combination of drugs known as the "cocktail."

Hyperactive immune resistance brings blindness in old age
Age-dependent macular degeneration (AMD) is the commonest cause of blindness in the western industrialised nations. Hereditary changes in the regulation of the immune system influence the risk of contracting AMD.

New study of gene evolution could lead to better understanding of neurodegenerative disease
Genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found.

Why play a losing game? Study uncovers why low-income people buy lottery tickets
Although state lotteries, on average, return just 53 cents for every dollar spent on a ticket, people continue to pour money into them - especially low-income people, who spend a larger percentage of their incomes on lottery tickets than do the wealthier segments of society.

Make your own microfluidic device with new kit from U-M
A type of device called a "lab-on-a-chip" could bring a new generation of instant home tests for illnesses, food contaminants and toxic gases. But today these portable, efficient tools are often stuck in the lab themselves. Specifically, in the labs of researchers who know how to make them from scratch.

CMV infections affect more than just patients with compromised immune systems, researchers find
An infection due to a virus called cytomegalovirus (CMV), which most commonly affects people with compromised immune systems, can also affect hospital intensive-care patients who have no immune-system problems, University of Washington researchers have found.

Mindfulness meditation slows progression of HIV, study shows
CD4+ T lymphocytes, or simply CD4 T cells, are the "brains" of the immune system, coordinating its activity when the body comes under attack. They are also the cells that are attacked by HIV, the devastating virus that causes AIDS and has infected roughly 40 million people worldwide. The virus slowly eats away at CD4 T cells, weakening the immune system.

Giving an additional early vaccination may reduce measles outbreaks
Outbreaks of measles in developing countries may be reduced by vaccinating infants at 4.5 months of age as well as at the World Health Organization's recommended routine vaccination at 9 months, according to a study published on BMJ.com today.
