A recent study adds a new dimension to our understanding of Antarctic Peninsula climate change and the likely causes of the break-up of its ice shelves.
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.
A mother's emotional health and education level during her child's earliest years influence oral health at age 14, according to a new study.
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.
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.
Researchers have made a novel discovery that could have widespread clinical implications, potentially affecting everything from nutrient metabolism to obesity in children.
Scientists have manipulated the Set2 pathway to show how genes are faithfully copied.
Researchers, doctors and patients tend to agree that during the high-risk period after an attempted suicide, the treatment of choice is close contact, follow-up and personal interaction in order to prevent a tragic repeat. Now, however, new research shows that this strategy does not work.
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.
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.
The radula sounds like something from a horror movie -- a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a "prototype" radula found in 500-million-year-old fossils shows that the earliest radula was not a flesh-rasping terror, but a tool for humbly scooping food from the muddy sea floor.
By discovering how certain viruses use their host cells to replicate, microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.
