A Cosmic Bat in Flight  

Munich, Germany (SPX) Mar 19, 2019 ESO's Very Large Telescope (VLT) has caught a glimpse of an ethereal nebula hidden away in the darkest corners of the constellation of Orion (The Hunter) - NGC 1788, nicknamed the Cosmic Bat. This bat-shaped reflection nebula doesn't emit light - instead it is illuminated by a cluster of young stars in its core, only dimly visible through the clouds of dust.

In a new quantum simulator, light behaves like a magnet  

Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions.

Common cause in sudden death syndromes  

Sudden Infant Death Syndrome (SIDS) and Sudden Unexpected Death in Epilepsy (SUDEP) are syndromes that share many medical similarities but whose physiological causes are poorly understood. An opinion article publishing March 21 in the journal Trends in Neurosciences suggests that the inability for an individual to wake up when their CO2 blood levels rise, likely due to a faulty neural reflex, may be a shared cause for incidences of death in both disorders.

The evolution of brain tumors  

Scientists have found in a recent study that only three different genetic alterations drive the early development of malignant glioblastomas. At least one of these three cancer drivers was present in all tumors investigated. The tumors develop for up to seven years before they become noticeable as symptoms and are diagnosed. However, in contrast to their early development, glioblastomas, which return after therapy, share no concurrent genetic alterations.

It's Not Just Humans: Sun Bears Also Communicate by Mimicking Facial Expressions  

"A smile is infectious," so goes the cheesy saying. But there's actually some validity there.
