Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Phys.org / Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
Phys.org / Want a happier marriage? Study suggests one simple habit
Research has long shown that exercise benefits both physical and mental health. Now, a new study from researchers at BYU suggests that it may also strengthen marriages, especially when couples exercise together.
Medical Xpress / People carrying a rare gene variant have naturally low body fat, healthier livers and better blood sugar levels
There are people around us who can maintain their weight despite what they eat. This has led scientists to believe that a person's metabolism and tendency toward obesity may have genetic factors behind them. A large study ...
Medical Xpress / Lonely people can feel their heartbeat clearly like everyone else, but their brains respond differently
For a long time, psychologists have described loneliness as the discomfort that comes from wanting more social connection than we feel we have, but there is more nuance to loneliness. Scientists are increasingly finding that ...
Phys.org / Arctic fossil abandoned in 1948 proves to be record-size Triassic hunter
Nearly 80 years ago, a British expedition discovered the battered remains of a giant fossil on the peak of an Arctic island. Unable to take it with them, they snapped some pictures, took some bones and left the fossil to ...
Phys.org / Galactic spins carry fingerprints of the primordial universe
The origin of spin in spiral and elliptical galaxies has posed a long-standing puzzle for astronomers. One idea, known as tidal torque theory, proposes that galaxies' spins are an imprinted record of the early universe, imparted ...
Phys.org / The impact of recent super El Niños on sea level rise
El Niños and La Niñas are the third-most dominant influences on Earth's climate, after the sun and the greenhouse effect. But they haven't been easy to decipher or to predict in terms of when they will happen and what exact ...
Phys.org / Crossing into a mirror world: Particles turn to wisps of fog, and the magnetic monopole paradox dissolves
In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"—my ...
Phys.org / Weather prediction hits a theoretical 129-day ceiling
Prediction is the goal and test of all science, one might argue. Meteorologists have been curious about the inherent limits of weather forecasting ever since the dawn of numerical weather prediction in the late 1950s.
Phys.org / Why some male anglerfish parasitically fuse with females
Reproduction is central to the survival of all living organisms. Over millions of years, animal species on Earth have evolved a remarkable variety of mating strategies, ranging from physical fights with competitors to mesmerizing ...
Phys.org / Ancient Colombians built huge water system without centralized rule, archaeologists say
Communities living in Colombia thousands of years ago achieved an engineering wonder of the world based on cooperation among family groups without top-down government, a new study shows. Archaeologists argue that policymakers ...
