Phys.org / Molecular makeover brightens organic light near 1,000 nanometers
Near-infrared organic light-emitting diodes (OLEDs) that emit about 1,000 nanometers could support biomedical and security technologies. Yet pushing organic light to these longer wavelengths usually causes a steep drop in ...
Medical Xpress / Mimicking natural connections could improve rotator cuff repair
Researchers have developed a "scaffold" that mimics natural tissue and could lead to more durable rotator cuff repairs, including for large injuries and cases involving bone and tissue degeneration that are often the most ...
Phys.org / LST-1 and MAGIC telescopes shatter distance record for the very high-energy blazar OP 313
On Aug. 15, the CTAO LST Collaboration and the MAGIC Collaboration released findings from observations of OP 313, the most distant very-high-energy blazar ever recorded. The paper, published in Astronomy & Astrophysics, presents ...
Phys.org / Specific cover crops may help attract insects that target harmful pests
Different cover crops may affect how plants defend themselves against pests—including by attracting more insects that eat harmful caterpillars—according to a new study led by researchers at Penn State's College of Agricultural ...
Phys.org / Simulations reveal asymmetric diffusion of magnetic skyrmions through an off-center gate
Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a key role in many fields, including physics, biology and economics. In particular, asymmetric or ...
Tech Xplore / Spy-device detector users miss nearly 60% of hidden gadgets
Consumer detectors sold to help people find hidden surveillance devices are often too difficult for typical users to interpret, potentially giving a false sense of security to those most at risk such as domestic abuse survivors, ...
Medical Xpress / Digital pets boost daily activity by more than 20%, trial finds
According to a master's thesis at the Norwegian University of Science and Technology (NTNU), a mobile game can make physical activity more enjoyable. Two master's students investigated how the mobile game "BitPet" affects ...
Phys.org / Natural gas drilling could raise salt levels, in turn boosting radium in water
Pennsylvania ranks second in U.S. natural gas production, accounting for about one-fifth of U.S. output in 2024, and has one of the most extensive histories of energy extraction in the country. A team of researchers from ...
Phys.org / Short, intense storms gain intensity across Hawaiʻi
While long-term data show that Hawaiʻi is getting drier overall, short, intense downpours that cause sudden, dangerous flash floods are getting stronger on the islands, according to a new study by researchers at the University ...
Phys.org / A 2-degree twist creates a nanoscale grid that traps light energy at room temperature
You may have once tried taking a close-up picture of a computer screen and noticed a wavy, rippling effect. This optical effect occurs whenever two fine, repeating grids overlap and slightly misalign, such as when the pixel ...
Phys.org / The hidden chemistry behind glow-in-the-dark art
Some of the world's brightest colors don't just reflect light; they create it. Scientists and museum conservators are now uncovering why these luminous pigments fade and how to preserve them for future generations. The findings ...
Medical Xpress / Temperature extremes can increase risk of heart failure hospitalization, study shows
Heart failure hospitalization risk increases after short-term exposure to cold spells, lower ambient temperatures and higher ambient temperatures, according to a study published in JACC and presented at ESC Congress 2026. ...
