New simulations show how planets form and maintain an orbit around a developing solar system. Until now, models plunged Earth-like objects into the stars they orbit.
Bioengineers have taken a small step toward improving physical recovery in stroke patients by showing that a key feature of how limb motion is encoded in the nervous system plays a crucial role in how new motor skills are learned. The study about the neural learning elements responsible for motor learning may help scientists design [...]
Researchers have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture.
A tumor’s genetic profile is often useful when diagnosing and deciding on treatment for certain cancers, but inexplicably, genetically similar leukemias in different patients do not always respond well to the same therapy. Researchers believe they may have discovered what distinguishes these patients by evaluating the “epigenetic” differences between patients with acute myeloid leukemia.

Scientists have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. Their findings have potentially important implications for understanding global climate, both past and future.

Rheumatoid arthritis (RA) patients are partially protected by the influenza vaccine 6-10 months after treatment with rituximab. Researchers determined that while the flu vaccine is safe, it is ineffective for RA patients in the first six months following rituximab treatment.
You can conserve fish and eat them too, according to a fisheries economist.

There is no evidence to support psychological debriefing in schools after traumatic events such as violence, suicides and accidental death, which runs counter to current practice in some Canadian school jurisdictions, according to a group of experts.

An analysis of 27 years of data shows that polar bears in the southern Beaufort Sea region are occurring more frequently on land and in open water than on ice during the fall.
