Phys.org / Researchers identify enzyme that prevents chromosome breaks during DNA copying
Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could affect how certain cancer ...
Phys.org / How studying friendship has changed the way I understand my own loneliness
A few years ago, I had just moved into a house.
Phys.org / Picturing Earth in a new light
Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming.

A NASA spacecraft chasing a rare metal asteroid swings past Mars this week for a gravity boost, snapping thousands of pictures as practice for the main encounter in 2029.
Medical Xpress / The newborn vitamin K shot: What every parent needs to know
When a baby is born, hospital staff move quickly through a standard checklist of newborn care: taking measurements, administering antibiotic eye ointment to prevent eye infections, and giving a small injection of vitamin ...
Medical Xpress / Antidepressant use in pregnancy shows no clear autism or ADHD link
Current evidence does not support a causal link between the use of almost all antidepressants during pregnancy and an increased risk of neurodevelopmental disorders, including autism and attention-deficit/hyperactivity disorder ...
Science X / Dinosaurs had company in the dark: Amber fossil reveals an ancient glow that lit Cretaceous nights
Forget what you thought you knew about fireflies. A remarkable discovery reveals their iconic glow was already lighting up the world when dinosaurs still roamed.
Medical Xpress / Genes give neurons a 'GPS' to form the brain's neural circuits, scientists show
How complex neural circuits are genetically designed and wired is a fundamental question in neuroscience. Scientists have shown for the first time that genes encode a "wiring map" that guides neurons to connect with the correct ...
Phys.org / Cut marks on 1.6 million-year-old bones reveal early humans moved prized meat
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate ...
Medical Xpress / Engineered brain 'bypass' that rewires specific circuits could boost resilience to stress
Broken or disrupted circuits in the brain contribute to many neurological disorders. A new custom-built biological "wire" developed at Duke University School of Medicine points the way toward a new treatment approach—bypassing ...
Phys.org / Tiny ocean life helps scientists estimate whale prevalence off the California coast
A new approach to better assessing whale population data has emerged, led by a research team of marine biologists from Scripps Institution of Oceanography at UC San Diego and statisticians from Cal Poly. Scientists typically ...
Phys.org / Satellite launch pollution is rapidly accumulating in the upper atmosphere
The potent pollution from so-called megaconstellation satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, ...
