Phys.org / Powerful UFO spotted blasting from a distant black hole
Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct ...
Phys.org / Tropical ocean temperatures may drive changes in malaria cases in Malawi
Malaria is one of the world's deadliest infectious diseases. Because it is transmitted by mosquitoes, malaria is extremely sensitive to environmental conditions like rainfall and temperature that affect mosquito survival ...
Phys.org / Could Earth have sent life to Jupiter's moon Europa?
Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal ...
Phys.org / Baby fossils reveal link between human and Neanderthal development
An international study of infant remains from 50,000–75,000 years ago has provided new evidence about the developmental trajectory of our evolutionary "cousins," Neanderthals.
Tech Xplore / Spin-orbit torque hardware creates random keys and reveals unauthorized access attempts
The information exchanged by modern devices is typically protected by cryptographic techniques, approaches that convert readable data into scrambled, unreadable code that can only be deciphered by authorized parties or devices. ...
Phys.org / Ancient mud drilled from Antarctic ice holds clues to future sea-level rise
"What goes on in Antarctica doesn't stay in Antarctica—it has global implications," Geology tauira Natalie-Jane Reid says. Reid is one of two Otago Ph.D. candidates who contributed to an Antarctic sediment core workshop at ...
Phys.org / Industrial fisheries discarded 80,000 metric tons of fish from 1950 to 2022, study finds
Destructive fishing practices and inadequate management allowed industrial fisheries operating in the waters of Saint Pierre and Miquelon to dump about 80,000 metric tons of fish back into the ocean from 1950 to 2022, with ...
Phys.org / Behavioral flexibility in foraging habits may help animals survive
Habits are often seen as automatic and inflexible behaviors. But a new study, published in Evolution Letters, suggests that habits may have evolved as a way for animals to handle several tasks at once. By shifting to habitual ...
Phys.org / Deep learning helps discover hundreds of Antarctic earthquakes coming from an unlikely location
Most of the earthquakes we hear about are due to tectonic plates colliding or sliding past each other near plate boundaries. Yet researchers have detected some enigmatic earthquakes happening inside the more stable interiors ...
Medical Xpress / People who lift weights live longer: New study
Strength training has long been seen as something you mainly do to build muscle or look good. But a new study adds to a growing body of evidence showing that lifting weights does far more than change how we look. It may help ...
Phys.org / Both rich and poor buy more counterfeits than the middle class, study finds
Conventional wisdom suggests that counterfeit luxury goods are primarily purchased by consumers who cannot afford authentic products. But recent research published in Marketing Science challenges that assumption, finding ...
Phys.org / 'Too pretty to do math'? Here's the real reason girls aren't choosing to study math
The T-shirt is yellow, 100% cotton and meant for "everyday wear." Across the front, it declares in italic script, "I'm too pretty to do math."
