There’s New Evidence for How Loneliness Affects Memory in Old Age
A new six‑year longitudinal study of 10,217 Europeans aged 65‑94 found that loneliness is linked to lower initial scores on immediate and delayed recall tests, but it does not accelerate the rate of memory decline. Age, depression and chronic illnesses were the dominant factors shaping both baseline memory and its trajectory. Physical activity was associated with higher baseline memory, acting as a protective buffer without altering decline speed. The research underscores loneliness as a modifiable risk factor for early‑stage cognitive performance rather than progressive deterioration.
How Can Astronauts Tell How Fast They’re Going?
Spacecraft cannot rely on conventional speedometers, GPS, or visual cues to gauge their motion. Instead, engineers combine Doppler tracking, inertial measurement units, and optical navigation to derive velocity with high precision. Each technique offers a different perspective—radial speed from frequency...
6,000 Meters Under the Pacific, Japan Seeks Independence From China on Rare Earths
Japanese scientists have successfully retrieved sediment samples containing rare‑earth elements from the seabed near Minamitorishima at depths of up to 6,000 meters, marking the world’s first such deep‑sea operation. The deposit is estimated to hold more than 16 million tons of...
This Beanie Is Designed to Read Your Thoughts
California startup Sabi has emerged from stealth with a brain‑reading beanie that translates imagined speech into text. The wearable relies on an ultra‑dense EEG array of 70,000‑100,000 sensors and a brain‑foundation AI model trained on 100,000 hours of data from...
NASA Wants to Put Nuclear Reactors on the Moon
NASA, together with the Departments of Defense and Energy, announced a plan to deploy nuclear reactors in orbit by 2028 and on the Moon’s surface by 2030. The reactors will initially deliver at least 20 kW of electricity for three years...
You Should Be More Freaked Out by Shingles
Shingles, caused by reactivation of the chickenpox virus, afflicts roughly one‑third of the population, with risk sharply increasing after age 50 or in immunocompromised individuals. The disease can lead to post‑herpetic neuralgia (PHN), a chronic nerve pain that may last years...
Flight Path Data Shows How Mosquitoes Target Humans
Scientists from Georgia Tech and MIT applied Bayesian inference to more than 53 million data points, creating a dynamic model of Aedes aegypti flight with fewer than 30 parameters. The research uncovered two flight modes—active and idle—and demonstrated that mosquitoes are...
No One Knows Where US Vaccine Policy Goes Next
Health and Human Services Secretary Robert F. Kennedy Jr. has stalled his sweeping vaccine overhaul after a federal judge invalidated the newly appointed ACIP members and blocked changes to the childhood immunization schedule. Kennedy’s earlier moves—dropping Covid‑19 recommendations for healthy...
How and When to Watch the Artemis II Mission’s Return to Earth
NASA’s Artemis II crew will complete a 10‑day lunar flyby and begin re‑entry of the Orion capsule in early May 2026. The mission’s return will be broadcast worldwide, with the splashdown expected in the Pacific Ocean near Hawaii. NASA plans a...
Artemis II Astronauts Witnessed 6 Meteorites Colliding With the Moon
During the Artemis II flyby of the Moon’s far side, astronauts aboard Orion reported six brief white‑blue flashes caused by meteorite impacts. The crew was 6,000‑7,000 km away and observed the events while a solar eclipse darkened the lunar surface, making the...
Iran War Puts Global Energy Markets on the Brink of a Worst-Case Scenario
The war between Israel and Iran has escalated into direct strikes on oil and gas infrastructure, effectively closing the Strait of Hormuz and pushing crude prices above $100 a barrel. Missile attacks have damaged the South Pars gas field and...
A Quantum Leap for the Turing Award
Charles Bennett and Gilles Brassard, pioneers of quantum information theory, have been awarded the ACM A.M. Turing Award. Their 1979 collaboration produced the BB84 protocol, the first quantum key distribution scheme, and laid the groundwork for quantum teleportation and the...
Interstellar Comet 3I/Atlas Has Another Surprise: It’s Full of Alcohol
Interstellar comet 3I/Atlas, the third confirmed object from beyond the solar system, is departing at 60 km/s after a close solar pass. New ALMA data show its coma contains methanol concentrations up to four times higher than typical solar comets, making...
Sleep Apnea Often Goes Undetected in Women. That’s Starting to Change
Obstructive sleep apnea, long viewed as a male‑dominant disorder, is now recognized as a major, often hidden health issue for women, especially during perimenopause and menopause. A Lancet Respiratory Medicine projection estimates 30.4 million U.S. women could have OSA by 2050,...
