How to weigh stars with gravitational lensing  

Astronomers have published the predictions of the passages of foreground stars in front of background stars. A team of astronomers, using ultra-precise measurements from the Gaia satellite, have accurately forecast two passages in the next months. Each event will produce shifts in the background star's position due to the deflection of light by gravity, and will allow the measurement of the mass of the foreground star, which is extremely difficult to determine by other means.

A clinical trial of the use of adrenaline in cardiac arrests has found that its use results in less than 1 percent more people leaving hospital alive -- but almost doubles the risk of severe brain damage for survivors of cardiac arrest. The research raises important questions about the future use of adrenaline in such cases and will necessitate debate amongst healthcare professionals, patients and the public.

A peek into the interplay between sleep and wakefulness  

The ventrolateral preoptic nucleus (VLPO) in the brain plays a critical role in the initiation and maintenance of sleep, while the lateral posterior part of the hypothalamus contains neuronal populations implicated in maintenance of arousal. Now, a new study reveals that these arousal-related neurons are heavily innervated by GABAergic neurons in the preoptic area including the VLPO. The work provides important information to understand the mechanisms that control animals' sleep/wakefulness stat
