Phys.org / Azide-to-diazo reaction unlocks safer path to versatile nitrogen-rich compounds
In the world of organic chemistry, nitrogen-containing organic compounds are ubiquitous, forming the backbone of pharmaceuticals, agrochemicals, dyes, and functional materials. To build these important molecules, chemists ...
Phys.org / Green alley effectiveness depends on design and purpose, study finds
Green alleys—residential laneways redesigned to enhance residents' quality of life, boost social cohesion and improve biodiversity—are gaining traction in cities across North America. But as the concept spreads, it remains ...
Science X / The keyboard trap: Why your best arguments are failing online
While 84% of people prefer to type out a disagreement, new research involving 1,842 conversations reveals that the "safer" choice is actually fueling social friction. In an era of digital flame wars and rising political partisanship, ...
Phys.org / When the Schuylkill swallowed the city: Lessons from Hurricane Ida's historic flood
New Penn research shows that Hurricane Ida wasn't a once-in-a-century anomaly but a preview of how climate change, urbanization, and aging infrastructure are rewriting flood risk.
Phys.org / Long-term study of COVID lockdown and family life shows unexpected, lasting effects on fatherhood
In the years following the COVID-19 pandemic, much has been said about how the lockdowns created conditions for dual-parent families to spend more time at home with their children. In an ideal vision of family life, this ...
Phys.org / Bacterial defense system builds DNA in unexpected new way to stop viruses
Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called reverse transcriptases, ...
Tech Xplore / Computer vision helps observers understand how iconic artworks were created
Paintings are often made up of thousands of tiny brushstrokes, each going in a certain direction, that are not easily observed by the viewer. A cross-disciplinary research team from the Penn State College of Information Sciences ...
Phys.org / Quantum computing's next dark horse emerges from a frozen surface, where almost nothing behaves as expected
Quantum bits (qubits) are the fundamental building blocks of quantum information processing. A novel qubit platform invented at the U.S. Department of Energy's (DOE) Argonne National Laboratory exhibits noise levels thousands ...
Medical Xpress / Skull microchannels reveal hidden route for brain immune defense
A study led by Rafael Gallareto-Sande, a predoctoral researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), provides new insights into a network of tiny blood vessels within the cranial bones ...
Medical Xpress / Excessive cholesterol in astrocytes linked to cognitive decline in Alzheimer's mice
Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...
Tech Xplore / A new type of optical chip cuts static power while enabling electrical reprogramming
As technology advances, and the demand for faster, higher-bandwidth, and more energy-efficient data processing continues to grow, scientists and engineers search for ways to improve electronic systems. One avenue they have ...
Medical Xpress / A gene that keeps intestinal stem cells stable offers insight into how tissues repair themselves
Years before he conducted the research that would earn him a Nobel Prize in Physiology and Medicine, Shinya Yamanaka, MD, Ph.D., was a postdoctoral scientist at Gladstone Institutes, studying genes. There, he helped discover ...
