A new study from West Virginia University researcher Eric E. Kelley -- in collaboration with the University of Minnesota -- suggests that unrepaired DNA damage can increase the speed of aging.

University of Colorado Denver researchers announced the development of a new method to increase the utility and equity of large genetic databases.

All coronaviruses produce four primary structural proteins and multiple nonstructural proteins. However, the majority of antibody-based SARS-CoV-2 research has focused on the spike and nucleocapsid proteins. A study published in PLOS Biology by Anna Heffron, Irene Ong and colleagues at the University of Wisconsin-Madison, USA, suggests that immune responses may develop against other proteins produced by the SARS-CoV-2 virus.

The first population-based national study comparing mental and physical health of lesbian, gay and bisexual Americans to their straight counterparts revealed that younger generations are worse off than Baby Boomers.

This involves the DYW deaminase domain of what is referred to as the RNA editosome. The DYW domain alters messenger RNA nucleotides in chloroplasts and mitochondria and contains a zinc ion whose activity is controlled by a very unusual mechanism. The team has now described this mechanism in detail for the first time. Their study is considered a breakthrough in the field of plant molecular biology and has far-reaching implications for bioengineering.

A commonly studied perovskite can superfluoresce at temperatures that are practical to achieve and at timescales long enough to make it potentially useful in quantum computing applications.

The first plant embryo gene expression atlas at the single cell level was developed by a team of researchers at GMI - Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences. The work, published in the journal Development, is a milestone on the way to uncovering the molecular mechanisms that determine how the most fundamental plant cell-types are established at the beginning of life.

The word "tsunami" brings immediately to mind the havoc that can be wrought by these uniquely powerful waves. The tsunamis we hear about most often are caused by undersea earthquakes, and the waves they generate can travel at speeds of up to 250 miles per hour and reach tens of meters high when they make landfall and break. They can cause massive flooding and rapid widespread devastation in coastal areas, as happened in Southeast Asia in 2004 and in Japan in 2011.

Tulsa, OK went from a severely flood-prone city to one of the most successful in the country in terms of flood control. A new study shows the importance of collaboration and empathy and how that transition mirrors the evolution of jazz.

The "flash" process developed at Rice University can turn carbon black into functionalized nanodiamond and other materials. The carbon atoms evolved through several phases depending on the length of the flash.

A study from Washington University School of Medicine in St. Louis suggests that many, but not all, COVID-19 therapies made from combinations of two antibodies are effective against a wide range of virus variants. Further, combination therapies appear to prevent the emergence of drug resistance.

New study investigates effect of increased dietary potassium from a whole food -- baked/boiled potatoes and baked French fries -- or a potassium supplement on blood pressure and other cardiovascular disease risk factors compared to a 'typical American' (lower potassium) diet. Results showed including baked/boiled potatoes as part of a typical American diet had the greatest benefit on sodium retention, even more than the supplement, and resulted in greater systolic blood pressure reduction than the control diet.

It's a treasure trove of data: the global vegetation database 'sPlotOpen' is now freely accessible. It contains balanced, representative data on vegetation from 114 countries and from all climate zones on Earth. The database was compiled by an international team of researchers led by Martin Luther University Halle-Wittenberg (MLU), the German Centre for Integrative Biodiversity Research (iDiv) and the French National Centre for Scientific Research (CNRS).

The use of statin therapy in adults 65 years old or older is not associated with incident dementia, mild cognitive impairment (MCI) or decline in individual cognition domains, according to a study published in the Journal of the American College of Cardiology (JACC).

Data captured in NCDR registries is similar in quality, depth and granularity when compared to data captured through clinical trials, according to research in JACC: Cardiovascular Interventions that compared data from the DAPT Study to NCDR CathPCI Registry data. This is good news for streamlining data collection and supports recent efforts to standardize data elements and definitions used in clinical trials and registries.

A high body mass index (BMI) during adolescence is a significant risk factor for Type 2 diabetes, early heart attack and overall poorer health for young adults, regardless of BMI in adulthood, according to a research letter published today in the Journal of the American College of Cardiology.

An international team led by Xavier Trepat at IBEC, with support from "La Caixa Foundation, measures the cellular forces in mini-intestines grown in the laboratory, deciphering how the inner wall of this vital organ folds and moves. The study, published in Nature Cell Biology, opens the doors to a better understanding of the bases of diseases such as celiac disease or cancer, and to the ability to find solutions for gut diseases through the development of new therapies.

New findings published this week in Physical Review Letters suggest that cosmic ray nuclei of hydrogen, carbon and oxygen travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently.

In The Optical Society (OSA) journal Optics Express, researchers demonstrate a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum technologies.

Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly in a steep drop-off have been largely unknown. However, new research from the University of Massachusetts Amherst reveals, with unprecedented detail, how the grain size of beach sand relates to the slope of the beach itself. These new findings are critical to understanding how New England's beaches will respond to both rising sea levels and increased storm activity.
