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.

New gene editing approach bypasses disease-causing mutations

A new approach to gene editing using the CRISPR/Cas9 system bypasses disease-causing mutations in a gene, enabling treatment of genetic diseases linked to a single gene, such as cystic fibrosis, certain types of sickle cell anemia, and other rare diseases.

Study finds raised levels of specific immune cells in asymptomatic people with COVID-19

The largest study of its type in the UK has identified differences in the immune response to COVID-19, between people with no symptoms, compared to those suffering a more serious reaction to the virus.

Sustainable green hydrogen to reduce greenhouse gas emissions

It's no secret the carbon emissions that result from using fossil fuels to produce energy are problematic for the planet. One way to make a dent in reducing these greenhouse gas (GHG) emissions is to find renewable ways to power the American manufacturing industry, which today is largely fueled by petroleum and natural gas.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Study reveals the multi-dimensionality of microplastic pollution

Microplastics--small plastic pieces less than 5 millimeters in length--are ubiquitous in the environment, and they can have significant effects on wildlife.

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.

Researchers uncover a key genetic culprit in the development of acute lymphoblastic leukemia

Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists at Johns Hopkins Medicine and Johns Hopkins Kimmel Cancer Center say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).

Study highlights the importance of autophagy in gene regulation

A fine balance between the production and degradation of biomolecules is required for optimal cell function. Autophagy is a mechanism through which cells break down and recycle their own components.

Study: Interaction between distant parts of RNA can regulate gene expression

Russian researchers have now investigated the role of double-stranded fragments of the maturing RNA and demonstrated that the interaction between faraway parts of the RNA can control gene expression.

Study shows how tau aggregates promote Alzheimer’s disease

If looked deep into the brain of a patient with Alzheimer’s disease or those suffering from the most types of dementia or the concussion-associated syndrome, called chronic traumatic encephalopathy (CTE), there would be hairball-like tangles of a protein known as tau—a common suspected culprit.
