In the U.S., one in five of the 37 million adults who has diabetes doesn’t know it. Current methods of diagnosing diabetes and prediabetes usually require a visit to a doctor’s office or lab work, both of which can be expensive and time-consuming. Now, diagnosing diabetes and prediabetes may be as simple as breathing.

A research team led by Huanyu “Larry” Cheng, James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, has developed a sensor that can help diagnose diabetes and prediabetes on-site in a few minutes using just a breath sample...

It’s a fact of life: Some people age better than others. Some ease into their 90s with mind and body intact, while others battle diabetes, Alzheimer’s or mobility issues decades earlier. Some can withstand a bad fall or bout of the flu with ease, while others never leave the hospital again.

New University of Colorado Boulder-led research, published in Nature Genetics, sheds light on why that is.

In it, an international team of co-authors identifies more than 400 genes associated with accelerated aging across seven different sub-types. The study reveals that different groups of genes underlie different kinds of disordered aging, a.k.a. frailty, ranging from cognitive decline to mobility issues to social isolation.

The findings lend support to what is known as the “geroscience ...

The ability to correct disease-causing genetic mistakes using genome editors holds great promise in medicine, but it is not without risk. When this type of “genetic surgery” is performed on DNA, for instance, there is always the danger of leaving permanent genetic scars that may even be heritable.

To alleviate this risk, researchers have experimented with gene editing processes on messenger RNA (mRNA), a central link between DNA and proteins that doesn’t carry the same risks because it doesn’t involve permanent changes to the DNA. But existing RNA editing tools have proven either too cumbersome to use or too toxic to human cells.

Yale researchers have developed a new—and safe—family of RNA-editing tools th...
