A team of researchers from the Keck School of Medicine of USC have published the first detailed description of the interplay between two cell types that allow lizards to regenerate their tails. This research, funded by the National Institutes of Health and published on August 10 in Nature Communications, focused on lizards’ unusual ability to…

New research indicates that screen time does not significantly affect the development of language, literacy, and math skills in preschoolers from low-income and minority homes. However, very high screen usage, especially during nighttime, can slightly hinder some social and behavioral skills. Negative impacts on some skills limited to high media use. New research indicates that…

Scientists can finally hunt down a harmful kind of human T cell, thanks to new research led by scientists at La Jolla Institute for Immunology (LJI) and the Medical College of Georgia (MCG) at Augusta University. Immune cells called ex-T regulatory cells (exTregs) tend to be rare in the body and, so far, impossible to…

Long COVID can persist for at least a year after the acute illness has passed, or appear months later, according to the most comprehensive look yet at how symptoms play out over a year. The multicenter study, a collaboration between UC San Francisco, the Centers for Disease Control and Prevention (CDC) and seven other sites,…

A change in just one letter in the code that makes up a cancer-causing gene can significantly affect how aggressive a tumor is or how well a patient with cancer responds to a particular therapy. A new, very precise gene-editing tool created by Weill Cornell Medicine investigators will enable scientists to study the impact of…

A vacuum chamber is never perfectly empty. A small number of atoms or molecules always remain, and measuring the tiny pressures they exert is critical. For instance, semiconductor manufacturers create microchips in vacuum chambers that must be almost entirely devoid of atomic and molecular contaminants, and so they need to monitor the gas pressure in…

Using human “mini-brain” models known as organoids, Mayo Clinic and Yale University scientists have discovered that the roots of autism spectrum disorder may be associated with an imbalance of specific neurons that play a critical role in how the brain communicates and functions. The specific cells are known as excitatory cortical neurons. The new study…

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of tumor DNA in a live organism. Their innovation, which detected cancer in the colons of mice, could pave the way to new biosensors…

This circle plot shows the correlation between age and DNA methylation age for various species estimated by the two universal clocks developed. Credit: Ake Lu and Steve Horvath Scientists at UCLA David Geffen School of Medicine and UCLA Health led an international research team that published two articles detailing changes in DNA—changes that researchers found…

A radiologist uses a magnifying glass to check mammograms for breast cancer AP2010 Can artificial intelligence (AI) help detect breast cancer? A new study out of Sweden has tentatively said: yes. The study enrolled over 80,000 women in a clinical trial to ask this question. All 80,033 underwent mammography. Half of those mammograms were interpreted…
