Dr. Henry Lee, who first stepped into the spotlight during a 1995 trial that captured national attention, has passed away at 87. He spent more than five decades teaching and guiding students in forensic science, shaping the field through both education and practice. Lee’s name is linked to several h
Pigs that eat a lot of copper in their food face a strange shift inside their stomachs. The extra metal changes the tiny community of bacteria that normally live there, and this can affect how Salmonella Typhimurium behaves. The Salmonella strain that has become a worldwide problem, called ST34,
NASA is changing its roadmap for the Moon. The agency has decided to stop work on the Gateway space station, a joint project that would have orbited the Moon. Instead, it will focus on building a permanent base on the lunar surface with an estimated cost of $20 billion. The new plan has three stages
A massive blue whale that drifted onto a southern Oregon beach in 2015 is about to reappear on land after an eleven‑year odyssey. The carcass, weighing roughly 200 tons and stretching nearly 70 feet, was found in a battered state. Scientists could not tell how long it had been dead, but tests reveal
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
