A New York City patient carrying a multi-drug-resistant strain of Klebsiella pneumoniae, a microbe frequently associated with hospital-borne infections, introduced the dangerous bacteria into the 243-bed research hospital while participating in a clinical study in the summer of 2011. To get the outbreak under control, medical researchers used genome sequencing in the middle of this active hospital epidemic to learn how the microbe spread.

Like recruiters pitching military service to a throng of people, scientists are developing drugs to recruit disease-fighting proteins present naturally in everyone’s blood in medicine’s war on infections, cancer and a range of other diseases.

A low dose of the sedative clonazepam alleviated autistic-like behavior in mice with a mutation that causes Dravet syndrome in humans. The mutation results in defective sodium ion channels. Affected brain cells cannot relay "hush" signals. An excess of excitatory signals results. Mice with this defect have seizures, impaired social interactions, learning difficulties, and freeze when confronting new mice or smells. Researchers overcame decreased sodium channel activity in mouse brain cells by increasing the strength of inhibitory signals with a common sedative.

Carbon nanotubes (CNTs) have potential uses in everything from medicine to electronics to construction. However, CNTs are not without risks. A new study found that they can be toxic to aquatic animals. The researchers urge that care be taken to prevent the release of CNTs into the environment as the materials enter mass production.

Formosan subterranean termites could be in for a real headache. Scientists have identified species of roundworms, or "nematodes," that invade the termite brains and offer a potential bio-based approach to controlling them.

Scientists have found that the ability to hear is lessened when, as a result of injury, a region of the brain responsible for processing sounds receives both visual and auditory inputs.

Intense prep courses for the Law School Admission Test are popular for good reason: They can improve scores significantly. Now neuroscientists have revealed the underlying impact of such preparation: The brain's neural connections change measurably, suggesting a bolstering of physical interconnections among reasoning areas of the brain. Diffusion tensor imaging scans of students before and after an intense three-month prep course showed increased connections between verbal and spatial reasoning areas of the brain.
