A study found that men, university graduates and optimists give themselves higher ratings for appearance, while those who score better on intelligence tests give themselves slightly lower ones. The scientists linked this to personality traits and demographics.
A study of 400 Brazilians found that people with dark personality traits tend to choose similar partners, but even fame, wealth and beauty do not make a criminal desirable.
Researchers proposed using impurities in scrap metal as alloying elements, yielding stronger cast iron and lower costs.
Physicists identified what interferes with silicon quantum bits operating simultaneously and proposed a way to compensate for the interference - operation fidelity remained above 99.9%.
A new study has identified thousands of young faults on the Moon's surface and estimated the rate of its contraction.
Japan's MMX spacecraft is set to launch to Mars to bring back samples from its moon Phobos for the first time in history, which could shed light on the Solar System's origins and conditions for life.
The Korea Research Institute of Standards and Science has re-measured the frequency of a key strontium atom transition, reducing the uncertainty more than 50-fold.
Computer modeling has shown that the mysterious hydrogen isotope composition in some volcanic rocks cannot be explained by the solidification of the ancient magma ocean. Scientists lean toward the idea that hydrogen has been seeping from the planet's metallic core for billions of years.
An international study has for the first time assessed where precision farming pays off and where it still lags. The main factor is the strictness of environmental regulations.
Japan's JAXA is preparing the first-ever mission to a moon of Mars that would return samples to Earth.
Researchers found a mathematical marker in the brain that can predict depression risk in adolescents long before complaints appear.
A national study in Finland found that young people referred to gender identity clinics receive specialized psychiatric care more often than peers, both before and after the first visit. The authors stress the data do not prove hormones or surgery caused this.
A Swedish study found that in patients with recurrent depression a single dose of psilocybin produced a rapid antidepressant effect, but its advantage over placebo diminished over time.
A study by Dutch scientists found that genetic variants linked to educational attainment are associated with fewer attention problems and stress complaints in children. The link runs mainly through the cognitive part of the index and is stronger in girls.
Norwegian scientists found a link between exclusive breastfeeding in the first six months and fewer ADHD symptoms in children. The effect is small, and it is a statistical association, not a proven cause.
Four Artemis II astronauts flew around the Moon and returned to Earth. Engineers confirmed the Orion heat shield performed as expected, with noticeably fewer cracks and charring than on the first mission.
Japanese researchers have created an automated setup for heat treatment, structural analysis and mechanical testing of bulk metals. The system works more than 10 times faster than manual experiments and paves the way for autonomous laboratories.
Laboratory tests showed that duct tape properly applied to the outside of a door sharply reduces leaks, while sandbags perform worse.
The Hubble telescope has captured an image of NGC 1827, seen edge-on, as part of a large program to study dwarf satellite galaxies.
British chemists have created liquids that glow with a unique pattern under ultraviolet light. By varying the proportions of components, many security labels can be produced without synthesizing new substances.
Modeling shows that by 2050 emissions from the battery supply chain would grow tenfold, but combining technology and sensible consumption could halve them.
A graduate student at the University of Sydney has created the first comprehensive classification of Martian soils and a map of their distribution. One class has been judged the most promising for growing plants - but only under controlled conditions.
Australian physicists have devised a way to hold LIGO detector mirrors using an invisible infrared laser, enabling new coatings and more precise detection of black hole collisions.
An experiment with 77 participants showed that oxytocin intensifies the emotional tone of memories about mother, and the effect depends on attachment anxiety.
Scientists found a link between brain "age," memory performance, mood and gut bacteria composition in people aged 18-65, but it is not a diagnosis or proof of cause.
