Dieting could be revolutionized, thanks to the groundbreaking discovery by the University of Warwick of the key brain cells which control our appetite.

Preschool instructors appear to lack the knowledge, skills and confidence to effectively teach their young students science -- a problem that is likely contributing to America's poor global performance in this crucially important subject.

As the US electricity grid continues to modernize, it will mean things like better reliability and resilience and lower environmental impacts, as well as new computing and communications technologies to monitor and manage the increasing number of devices that connect to the grid. However, that enhanced connectivity for grid operators and consumers also opens the door to hackers.

Adding or removing water from a stem cell can change the destiny of the cell to either pre-fat cells or pre-bone cells, researchers have discovered in a new study published in PNAS.

An Osaka University-led research group use an advanced synchrotron measurement system to probe how laser pulses affect the magnetism of ferrimagnetic materials of different compositions. Films with high gadolinium content showed magnetic spin flipping, and those with slightly less gadolinium featured spin precession precision at very high angles. These findings could assist in development of faster magnetic memory devices.
