Results suggest novel approaches to maintaining cognition as we age. Along with adding to the trove of research that shows these games can improve eye-hand coordination and reaction time, this finding shows the potential for novel virtual approaches to helping people who lose memory as they age or suffer from dementia.

METHOD: Before and after the 2wk period, the students took memory tests that engaged the brain’s hippocampus, associated with complex learning and memory. They were given a series of pictures of everyday objects to study...

It delivers drug directly via skin to where needed at a consistent dose rate. Researchers at the University of Warwick have worked with Coventry-based Medherant, a Warwick spinout company in developing a transparent adhesive patch that can consistently deliver a prolonged high dose of the painkiller ibuprofen directly through the skin. The University of Warwick researchers and Medherant have found a way to incoporate significant amounts of the drug (up to 30% weight) into the polymer matrix that sticks the patch to the patient’s skin with the drug then being delivered at a steady rate over up to 12 hours...

Ebselen affects the phosphoinositide cycle and has CNS effects on surrogate markers that may be relevant to the treatment of bipolar disorder, which can be tested in future clinical trials.

A drug destined for the scrap heap has been rescued by Oxford scientists. They used a database of ‘failed’ drugs, found to be safe but ineffective for their proposed use, to identify ebselen as a possible alternative to lithium, the main treatment for people who are bipolar.

Ebselen was under development as a treatment for stroke, but was abandoned by its manufacturer in the final phase of clinical trials. However, those trials proved that the drug was safe for use in humans. Initial tests of ebselen as a treatment for bipolar disorder were carried out in mice...

System combines biological ion channels with solid-state transistors to create a new kind of electronics. Researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from ATP, energy currency of life. They integrated a conventional solid-state complementary metal-oxide-semiconductor (CMOS) integrated circuit with an artificial lipid bilayer membrane with ATP-powered ion pumps, opening the door to creating entirely new artificial systems that contain both biological and solid-state components.

“We are excited at the prospect of expanding the palette...
