Phys.org / Dangerous heat wave roasts America's big birthday party
A punishing heat wave threatened America's July Fourth celebrations, World Cup matches and power grids as near-record temperatures scorched the eastern United States on Friday.
Phys.org / NASA rolls out three robotic moon missions as 2029 lunar base plans take shape
NASA on Tuesday announced new uncrewed missions to aid in the future creation of a lunar surface base, a project beginning to take shape despite recent setbacks.
Phys.org / Acceptor molecule upconverts low-energy green light to high-energy purple with high efficiency
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
Phys.org / World's oceans break June heat record: EU monitor
The world's oceans just experienced their hottest June on record and could set fresh highs in the months ahead as El Nino and climate change drive temperatures even higher, scientists said Wednesday.
Medical Xpress / Dementia-causing substance turns into a therapeutic 'switch' with new Alzheimer's drug strategy
A substance that worsens dementia has become a "switch" that initiates treatment. KAIST researchers have developed a new therapeutic approach that uses hydrogen peroxide (H₂O₂), a reactive oxygen species that damages cells ...
Phys.org / The largest digital camera ever built begins decade-long survey of the universe
The largest digital camera ever built is starting to capture images of unseen corners of the universe.
Phys.org / Newly discovered corn trait may help improve crop drought tolerance
Researchers report some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues and deeper roots, which helps them deal with drought. That's the conclusion of a team led by Penn ...
Medical Xpress / Precision fMRI maps prefrontal cortex in individuals, revealing fine-scale structures
Much like camera settings—filters, flashes and focus—affect what we notice in a final photo, the way scientists measure something can affect how we interpret and understand it. This is especially true when imaging things ...
Phys.org / Ancient gum disease may have helped reshape jaws before human brains expanded
Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors ...
Medical Xpress / COVID's lingering shadow faded after omicron—but not for everyone
Six years after the world first learned of COVID-19, the pandemic has faded into an unpleasant memory for many. For others, however, it never fully ended. A long-term study by Hiroshima University has found that while lingering ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
