Accurate distance measurement resolves major astronomical mystery
It was the famous double-star system with regular, bright outbursts that the theorists said shouldn't be happening. Getting its distance right, however, meant that its outbursts finally fit the standard model for how such systems work.

Bittersweet: Bait-averse cockroaches shudder at sugar
Sugar isn't always sweet to German cockroaches, especially to the ones that avoid roach baits. In a study published May 24 in the journal Science, North Carolina State University entomologists show the neural mechanism behind the aversion to glucose, the simple sugar that is a popular ingredient in roach-bait poison. Glucose sets off bitter receptors in roach taste buds, causing roaches to avoid foods that bring on this taste-bud reaction.

Antibiotics: A new understanding of sulfonamide nervous system side effects
Sulfonamide antibiotics are used against a wide spectrum of bacterial infections. However, their side effects can include serious neurological problems like nausea, headache, dizziness, hallucinations and even psychosis. Now, scientists at EPFL have uncovered the molecular basis behind some of the neurological side effects of sulfonamide antibiotics and have shown that they interfere with the production of dopamine in the brain by direct binding of the sepiapterin enzyme.

Research offers promising new approach to treatment of lung cancer
Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors -- the tumors virtually disappeared.

Reducing caloric intake delays nerve cell loss
Activating an enzyme known to play a role in the anti-aging benefits of calorie restriction delays the loss of brain cells and preserves cognitive function in mice, according to a study published in the May 22 issue of The Journal of Neuroscience. The findings could one day guide researchers to discover drug alternatives that slow the progress of age-associated impairments in the brain.

Researchers perform fastest measurements ever made of ion channel proteins
A team of researchers at Columbia Engineering has used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed. They designed a custom integrated circuit to perform these measurements, in which an artificial cell membrane and ion channel are attached directly to the surface of the amplifier chip.

Penn research makes advance in nanotech gene sequencing technique
The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole. Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base.

Slow earthquakes: It's all in the rock mechanics
Earthquakes that last minutes rather than seconds are a relatively recent discovery, according to an international team of seismologists. Researchers have been aware of these slow earthquakes, only for the past five to 10 years because of new tools and new observations, but these tools may explain the triggering of some normal earthquakes and could help in earthquake prediction.
