Phys.org / Why Kamchatka's magnitude 8.8 earthquake brought a smaller tsunami—and where risk may remain
On July 29, 2025, a magnitude 8.8 earthquake occurred near the Kamchatka Peninsula. It was so powerful that it ranks as the sixth-largest earthquake ever recorded by modern instruments. Using this giant earthquake as a learning ...
Phys.org / Invisible fertility crisis: Chemicals and climate change threaten reproduction across species
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated ...
Phys.org / Mechanochemistry simplifies synthesis of challenging conductive organic molecules
Mechanochemistry is a growing field for chemical reactions that proceed in the solid state in the absence, or with minuscule amounts, of solvent added. For decades, solvents have been considered conventional for the progression ...
Phys.org / Newly confirmed supernova remnant is one of the faintest ever detected
An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery ...
Science X / For centuries these dazzling Roman bowls were misread—until chemical traces exposed an unexpected maker
For centuries, archaeologists debated the origins of Rome's exquisite mosaic-glass bowls. Now, chemical fingerprints in 101 ancient shards point to a surprising center of production: Italy, not Egypt. This discovery challenges ...
Medical Xpress / Turning immune cells into tumor allies: A cancer cell protein can reprogram frontline defenders
Cancer cells can disarm the immune system not just by hiding from it, but by actively reprogramming nearby immune cells into a suppressed state. This previously unrecognized molecular interaction, discovered by scientists ...
Phys.org / A longstanding quantum roadblock just fell, opening existing fiber networks to ultra-secure light signals
Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can't be copied or split and thus are secure—in the network of optical fibers we already have. This opens ...
Phys.org / Why did Clovis toolmakers choose difficult quartz crystal? New study offers clues
Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...
Phys.org / Solar radio bursts reveal hidden magnetic switchbacks near the sun, Parker Solar Probe data suggest
Solar radio bursts are intrinsically linked to the motion of their emitting source through the coronal and heliospheric plasma. Electron transport is mostly confined to magnetic field lines. These electrons move at a substantial ...
Medical Xpress / Scientists recruit red blood cells to deliver genetic cargo with instructions to kill cancer
Scientists have developed a way to turn the body's own immune cells into cancer-fighting agents—without removing them from the body—by using red blood cells to deliver genetic instructions. Current CAR (chimeric antigen receptor) ...
Tech Xplore / Brain-inspired approach can teach AI to doubt itself just enough to avoid overconfidence
Most contemporary artificial intelligence (AI) systems learn to complete tasks via machine learning and deep learning. Machine learning is a computational approach that allows models to uncover patterns in data that are useful ...
Phys.org / Blood-based DNA marker tracks arsenic exposure and may predict toxicity risk
Public health experts estimate that more than 200 million people worldwide are exposed to arsenic through contaminated drinking water. Scientists know long-term exposure to arsenic is associated with increased risk of chronic ...
