While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world’s oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass.
Brain imaging shows that the brains of teens that use marijuana are working harder than the brains of their peers who abstain from the drug.

Researchers have developed a promising nanomaterial-based biomedical device that could be used to deliver chemotherapy drugs locally to sites where cancerous tumors have been surgically removed. The team demonstrated that the flexible microfilm device, which resembles a piece of plastic wrap and can be customized easily into different shapes, releases the chemotherapy agent doxorubicin in [...]

Scintists have discovered a novel mechanism that regulates how neural stem cells of the retina generate the appropriate cell type at the right time during normal development. These findings could influence the development of future cell replacement therapies for genetic eye diseases that cause blindness.

Rob Cardinal was looking for an asteroid, but ended up finding a comet. There is not much known yet about the Cardinal comet. Scientists are trying to determine more information about its orbit, whether its passing by Earth is periodic or whether it will only come by the sun once, which would mean its orbit [...]

We’ve all met know-it-alls — people who think they know more than they actually do. If they’re talking about products, like wine or motorcycles, they might actually know as much as they think. But when it comes to health plans, social policy, or nutrition, they might not, according to a new study in the Journal [...]

The widely held belief that the Nile valley was the most likely route out of sub-Saharan Africa for early modern humans 120,000 year ago is challenged. A new team shows that wetter conditions reached a lot further north than previously thought, providing a wet ‘corridor’ through Libya for early human migrations. The results also help [...]

A protein made by the liver in response to inflammation and used to treat patients suffering from a genetic form of emphysema has been shown to restore blood glucose levels in a mouse model of type 1 diabetes mellitus, according to a new study led by researchers at Beth Israel Deaconess Medical Center.

Developing neurons tend to play the field, making more connections than they will ever need. Then the weakest are cut. But scientists now show that neurons in young zebrafish — vertebrates, like humans — behave differently: They immediately find a cluster of specialized cells and make the right match. The findings may help reveal the [...]

The birth of new neurons (neurogenesis) does not end completely during development but continues throughout all life in two areas of the adult nervous system, i.e. subventricular zone and hippocampus. Recent research has shown that hippocampal neurogenesis is crucial for memory formation. These studies, however, have not yet clarified how the newborn neurons are integrated [...]
