Phys.org / How plants survive constant DNA damage: Newly identified repair protein protects growth-critical stem cells
Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and survival in plants. Every day, plants endure environmental stresses such as sunlight, radiation, drought ...
Phys.org / Tabletop experiment helps reconcile fundamental physics
Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that ...
Phys.org / Rocket launches and reentries harm Earth's ozone layer
The space industry is surging. In coming years, nearly 10,000 spacecraft are slated to launch into low-Earth orbit for a variety of purposes, such as global surveillance, space tourism, and satellite "megaconstellations" ...
Phys.org / Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on ...
Phys.org / Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy
Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of ...
Phys.org / Quantum circuits help AI overcome memory limitations with minimal new parameters
For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
Medical Xpress / New GLP-1 oral pill lowers blood sugar and reduces bodyweight, clinical trial finds
Oral GLP-1 medications have the potential to increase access to therapies that can help lower blood sugar and reduce bodyweight. At the American Diabetes Association's Scientific Session, Mass General Brigham physician investigator ...
Phys.org / Peptide blocks DNA breaks tied to treatment-induced leukemia, offering new prevention route
Thanks to effective therapies, more and more people are now able to live with or after cancer in the long term. Consequently, the number of patients affected by the long-term effects of their treatment is also increasing. ...
Phys.org / Headless skeletons offer new insights into farming societies 7,000 years ago
Dozens of human skeletons, lying apparently randomly on and next to each other, with their skulls missing, present a terrifying sight at first glance. Since 2022, this is what researchers have been excavating in a 7,000-year-old ...
Phys.org / Brazilian breadbasket's aquifers are falling, and new satellite maps show where water stress is growing
A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical ...
Phys.org / Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that ...
Phys.org / How Artemis II livestreamed hi-def videos and images from the moon to Earth
This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to ...
