Phys.org / Three energy-loss routes may explain Tarantula Nebula's X-ray shortfall
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the ...
Medical Xpress / Cancer-specific c-Myc mapping reveals overlooked SLK protein as treatment target
Using a photochemically driven labeling technique, a Cornell-led research group has devised a strategy for capturing cancer-specific protein–protein interactions, which could one day lead to targeted therapies for prostate, ...
Medical Xpress / 2005 to 2023 saw decrease in dual-energy X-ray absorptiometry testing for osteoporosis screening
From 2005 to 2023, there was a decrease in dual-energy X-ray absorptiometry (DXA) testing for osteoporosis among Medicare beneficiaries, with the largest decrease seen among Hispanic beneficiaries, according to a study published ...
Phys.org / Tiny floating magnet detects ultrafaint magnetic fields at room temperature
Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires expensive or bulky equipment, ...
Phys.org / Rivers are moving sediment in intense bursts, a worrisome new pattern uncovered by AI
After a heavy rain, rivers often turn brown with sediment, sand, silt and soil washed from the landscape that play a vital role in shaping rivers.
Phys.org / Boron layers could set a superconductivity record, theoretical study predicts
Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures ...
Tech Xplore / Graphene-powered soft lens could pave the way for smarter glasses, cameras and medical devices
The ability to change focus instantly is something most people take for granted. Every day, our eyes effortlessly switch between reading a book, recognizing a face across the room or watching a bird fly overhead. Replicating ...
Phys.org / Trapped gases in ancient rocks challenge global explanation for 2-billion-year-old carbon anomaly
Roughly 2.5–2 billion years ago, Earth's surface experienced the biggest chemical change in its history when oxygen became abundant in the atmosphere, eventually leading to the evolution of complex life forms such as plants ...
Medical Xpress / Scientists uncover cellular mechanism driving both rare childhood dementia and Alzheimer's disease
Researchers at the University of California San Diego and their colleagues have identified a key cellular pathway that drives brain degeneration in both a rare childhood disorder and the far more common Alzheimer's disease. ...
Phys.org / Tourists rush to Mount Etna as Italian volcano erupts
Spectacular images of lava flowing down the slopes of erupting Mount Etna have drawn flocks of tourists to the Italian volcano—to the worry of local guides.
Tech Xplore / How malicious SIM cards can hijack smartphones, EV chargers and connected devices
Subscriber Identity Modules (SIMs), secure elements used to connect devices to a mobile network, can pose severe security risks when compromised. A malicious SIM could allow attackers to gather information about a device, ...
Phys.org / Mice bred to run three times farther show no fertility or lifespan cost
Being an elite athlete—at least for a mouse—does not shorten lifespan or limit how many children one can have. This is the finding of a study 30 years in the making, and it runs counter to accepted evolutionary theory.
