Like batteries, fuel cells produce energy through an electrochemical process. Unlike batteries, they don’t run down or require recharging. However, the potential advantages of fuel cells are offset by challenges that include cost, performance and durability.

When a photon is scattered, the photon recoil changes the momentum of the atom by q (red arrow). a, Above the phase transition (T>TC), both the initial and final momentum states are in the thermal cloud. b, Below the phase transition (T
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.

Glucose extends lifespan in aged worms independently of the DAF-16 (FOXO). Differentially regulated genes downstream of the insulin/insulin-like growth factor signalling (IIS) (a), daf-16 (b), hsf-1 independently (ind.) of heat shock (HS) (c, d) in animals fed on the normal diet (ND) or high-glucose diet (HGD) from 5-day old (HGD-5). e Lifespan assays of daf-16(lof) animals fed on the ND or HGD-5 (ND, n = 502; HGD-5, n = 536 including biological replicates). f, g Representative images of DAF-16::GFP localisation in 1- (D1) and 5-day old (D5) worms on 16 h ND, HGD (filled circles) or 1 h heat shock (filled circles) at 37 °C (n = 60 for each condition including biological replicates). Scale bars represent 100 μm (f) and 25 μm (g). Highlighted worms with dashed lines are WT animals...Read More
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...
