Astronomers have taken a striking new image of a nearby galaxy that many astronomers think closely resembles our own Milky Way. Though the galaxy is seen edge-on, observations of NGC 4945 suggest that this hive of stars is a spiral galaxy much like our own, with swirling, luminous arms and a bar-shaped central region. These [...]

Researchers have now discovered that establishing the neural wiring necessary to function normally depends on the ability of neurons to make finger-like projections of their membrane called filopodia.

Can’t sleep at night? A new study has found that people who suffer from insomnia have heightened nighttime blood pressure, which can lead to cardiac problems. The investigation measured the 24-hour blood pressure of insomniacs compared to sound sleepers.

Levels of a biomarker used in the diagnosis of heart attacks are almost universally elevated in patients who have undergone coronary-artery bypass grafting (CABG) and, when markedly elevated, powerfully predict the risk of complications.

A new study looks at the highly sophisticated structure of teeth and how this structure could be applied to aircraft and space vehicles of the future.
Design students have been working on a national project to create symbols that will guide users in health-care settings — no matter a user’s language or reading level. The students are completing their work and testing begins soon.

Sticking with what you know often comes at the price of learning about more favorable alternatives. Managing this trade-off is easy for many, but not for those with conditions such as Alzheimer’s disease or obsessive-compulsive disorder who are trapped in simple routines. Using brain scans in monkeys, researchers are now able to predict when monkeys [...]

Potted plants add aesthetic value to homes and offices, and have been shown to remove volatile organic compounds (VOCs) gases or vapors emitted by solids and liquids that may have adverse health effects. But take heed when considering adding some green to your environment; in addition to giving off oxygen and sucking out harmful VOCs, [...]

Early in development, mammalian female cells counteract their double dose of X chromosomes by coating one of them with a large RNA named XIST. The RNA binds to the same X chromosome from which it is transcribed and initiates a series of events leading to the chromosome’s permanent silencing. Researchers recently exploited the fact that [...]
