A 59‑year‑old former Air Force officer, who has flown to space four times, told a news agency that he suddenly became ill while eating dinner on the International Space Station. The incident happened just days before a planned spacewalk, and his crew reacted immediately, calling for ground‑based med
A team of researchers from Japan and Germany discovered a way to make solar cells produce more useful energy than the light they absorb, reaching about 130 % efficiency. The trick involves a special molybdenum metal complex that can capture extra energy created by a process called singlet fission. I
The team that will circle the moon this year looks very different from the astronauts who first landed there in 1969. The group includes a woman, a person of color and a Canadian, reflecting the diversity of today’s space program. Commander Reid Wiseman, a 50‑year‑old former Navy captain and widowe
In adolescence, the brain’s “default mode, ” “central executive, ” and “salience” networks are thought to work together for social understanding. When these networks do not connect properly, people may find it hard to read others’ feelings or intentions. Researchers compared teens with autism spectr
People who follow famous people closely often feel a strong attachment to them. Studies show that this attachment can be linked to what psychologists call vulnerable narcissism – a form of self‑interest that feels fragile and depends on external validation. When someone spends a lot of time wa
The invention of real‑time PCR transformed how scientists measure DNA. Three decades ago, researchers checked amplified samples only after the reaction finished, using gels and visual scans. That method was slow and gave shaky results, making it hard to run many tests at once. A special anniv
Backcountry adventures are getting more popular, and people often bring avalanche tools like transceivers and airbags. These devices have helped many survive falls, but they can also change how people act in danger. When someone feels protected by gear, they may take bigger risks – a trick called ri
Parents of 523 children aged 7 to 12, most boys, filled out surveys about their kids’ daily habits and feelings. Researchers used a statistical method called latent profile analysis to spot patterns in four distinct groups. The first group, about one‑fifth of the sample, showed very high levels of
Scientists are exploring fresh markers in the body that could help spot problems linked to how we live. These new tools look at tiny molecules and signals in blood, sweat or even breath that change when we eat poorly, sit too long or smoke. By catching these clues early, doctors might offer advice t
Scientists teamed up with a popular mayo brand to find out if the creamy condiment can play music. The idea started as a joke on a cartoon, but researchers now say it can. They used science to test whether mayo can make or change sound in a clear way. The study looked at how instruments normally wo
