A new study suggests that exercise, even if not adopted until later in life, can slow the effects of aging. When 2-year old mice were studied after two months of progressive weighted wheel running, despite having no prior training, it was determined that they were the epigenetic age of mice eight weeks younger than sedentary mice of the same age.

For people who hate exercising, here comes some more bad news: it may also keep you younger. Not just looking younger, but actually younger, on an epigenetic level. By now, the benefits of exercise have been well established, including increased strength of bones and muscles, improved mobility and endurance, and lower risk of heart disease, diabetes and high blood pressure.

But younger?

A team of researchers from the National University of Singapore (NUS) has set a new record in the power conversion efficiency of solar cells made using perovskite and organic materials. This technological breakthrough paves the way for flexible, light-weight, low cost and ultra-thin photovoltaic cells which are ideal for powering vehicles, boats, blinds and other applications.

“Technologies for clean and renewable energy are extremely important for carbon reduction. Solar cells that directly convert solar energy into electricity are among the most promising clean energy technologies...

The findings could redefine the kinds of particles that were abundant in the early universe. Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland.

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons – elementary particles that briefly glommed together in countless combinations before cooling and settling int...

It took a global pandemic, but the critical role of messenger RNA in all of life’s functions has taken center stage in the past year with the successful rollout of mRNA vaccines to combat the SARS-Cov-2 virus.

In two new papers published the week of Jan. 17, the lab of Yale’s Wendy Gilbert sheds light on how mRNAs are born and how they regulate production of proteins inside of our cells once they reach maturity. The findings have implications not only for achieving effective doses for new vaccines, but for helping determine the biological roots of many cancers and diseases.

“It’s been exciting to be able to study the beginning and end of this process,” said Gilbert, associate professor of molecular biophysics and biochemistry.
