Medical Xpress / A molecular 'reset button' for reading the brain through a blood test
Tracking how genes switch on and off in the brain is essential for understanding many neurological diseases, yet the tools to monitor this activity are often invasive or unable to capture subtler changes over time. One emerging ...
Phys.org / Newly discovered star opens 'laboratory' for solving cosmic dust mystery
Seventy light-years from Earth, a star called Kappa Tucanae A harbors one of astronomy's most perplexing mysteries: dust so hot it glows at more than 1,000 degrees Fahrenheit, existing impossibly close to its host star, where ...
Phys.org / Smart hydrogels act as 'micromachines' to squeeze and study living cells
Within tissues, cells are embedded in complex, three-dimensional structures known as the extracellular matrix. Their biomechanical interactions play a crucial role in numerous biological processes. Scientists at the Max Planck ...
Phys.org / Coral reefs have stabilized Earth's carbon cycle for the past 250 million years, research reveals
Coral reefs have long been celebrated as biodiversity hotspots—but new research shows they have also played a much deeper role: conducting the rhythm of Earth's carbon and climate cycles for more than 250 million years.
Phys.org / Sounding the 6,000-year-old shell trumpets of Catalonia
Archaeologists have played shell trumpets from Neolithic Catalonia, revealing they were highly effective for long-distance communication and may have also been used as musical instruments.
Phys.org / Ant brood signal deadly infection in altruistic self-sacrifice
Ant colonies operate as tightly coordinated "superorganisms" with individual ants working together, much like the cells of a body, to ensure their collective health. Researchers at the Institute of Science and Technology ...
Phys.org / Zapping stem cells could boost growth of new tissues and organs
Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new improved ways of creating new tissues, organs, nerves and bones.
Medical Xpress / Nearly one in five child deaths linked to growth failure, global analysis finds
Nearly 1 million children around the globe fail to reach their fifth birthday every year due to devastating health consequences linked to child growth failure, making it the third leading risk factor for mortality and morbidity ...
Phys.org / What time is it on Mars? Physicists have the answer.
Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks.
Phys.org / How probation officers—criminal legal system's most diverse group—experience their roles
Probation officers—who supervise nearly 4 million people across the United States—are among the most visible faces of the criminal legal system (CLS). A new study led by UConn School of Social Work Assistant Professor ...
Phys.org / Tracking forever chemicals across food web shows not all isomers are distributed equally
When University at Buffalo chemists analyzed samples of water, fish, and bird eggs, they weren't surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, these "forever chemicals" turn up nearly ...
Phys.org / Are university policies holding science back? Study shows how patenting boosts pure research
When UC Berkeley biochemist Jennifer Doudna first began studying how bacteria fight virus infections, she had no idea it would result in one of the most important scientific breakthroughs of the century. Her curiosity-driven ...
