Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called “occupation number,” an effect known as bosonic stimulation. The appearance of bosonic stimulation in light scattering processes was first predicted over three decades ago, yet directly observing it in experimental settings has so far proved challenging.

The finding opens the door for a possible treatment for many liver diseases. A study identifies a molecule behind the runaway growth of bile duct cells inside the liver, which underlies many liver diseases.

The liver is the all-important organ behind processing of various substances we put into our bodies, from food and drink to alcohol and drugs. When things go awry with the liver, the consequences can be deadly. At the root of many liver diseases, from hepatitis to Non-Alcoholic SteatoHepatitis, commonly known as NASH, is scarring, otherwise known as liver fibrosis — and currently, there are no drugs available to treat this scarring.

Researchers are investigating the root causes of liver fibrosis in the hopes of identifying potential targets for drugs in the future...

Lakes are bodies of water fed by rainfall, snowmelt, rivers and groundwater, through which, Earth is teeming with life. Lakes also contain critical geologic records of past climates. Though Mars is a frozen desert today, scientists have shown that Mars contains evidence of ancient lakes that existed billions of years ago, which could contain evidence for ancient life and climate conditions on the red planet...
