Researchers solve the mystery of how many bubbles are in a glass of beer

After pouring beer into a glass, streams of little bubbles appear and start to rise, forming a foamy head. As the bubbles burst, the released carbon dioxide gas imparts the beverage's desirable tang.

New enzyme-activated compostable plastic could diminish microplastics pollution

Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment.

Scientists identify the odorants responsible for off-flavor-tainted cocoa

Musty, moldy, smoky or horse dung-like smelling cocoa is not suitable for chocolate production. As part of a larger research project, a team of scientists led by Martin Steinhaus from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has identified the odorants responsible for such off-flavors.

New method to measure the growth rate of disease-causing amyloid fibrils

Amyloid fibrils are deposits of proteins in the body that join together to form microscopic fibres. Their formation has been linked to many serious human diseases including Alzheimer's, Parkinson's and Type 2 diabetes.

Scientists engineer probiotic yeast to produce beta-carotene in the guts of mice

Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast.

POSTECH researchers bioengineer a novel drug-delivering adhesive patch platform

Blood vessels deliver nutrients and oxygen to each organ in our body. They are difficult to completely restore to their original conditions once damaged by myocardial infarction or severe ischemic diseases. This is because various angiogenic growth factors must be applied sequentially in order to restore the vascular structure.

Study explains molecular mechanisms of drug resistance in Mycobacterium tuberculosis

A group of researchers from France, Germany, Belarus, Japan, and Russia and headed by a scientist from Skolkovo Institute of Science and Technology (Skoltech) has discovered how Mycobacterium tuberculosis survives in iron-deficient environments by using rubredoxin B (RubB)—a protein that belongs to the rubredoxin family and plays a significant role in adapting to varying environmental conditions.

Inhibiting a specific protein could increase tumor sensitivity to PARP inhibitors

Researchers at the Francis Crick Institute have found that blocking a specific protein could increase tumor sensitivity to treatment with PARP inhibitors. Their work published in Science , suggests combining treatments could lead to improved therapy for patients with inheritable breast cancers.
