Phys.org / Radiocarbon dating rewrites angiosperm trees' lifespan records worldwide
For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes ...
Phys.org / Trees cover rock, eventually: Study maps how bare Georgia bedrock turns into forest
In the forests of the southeastern United States, dense tree cover dominates most landscapes. That's why the Appalachian Trail is sometimes nicknamed "The Green Tunnel." But avid hikers know that often in the Southeast, they'll ...
Medical Xpress / First gene regulation clinical trials for epilepsy show promising results
A Phase I/IIa clinical trials co-led by Linda Laux, MD, from Ann & Robert H. Lurie Children's Hospital of Chicago, show that the first gene regulation treatment for epilepsy is safe and well tolerated by patients with Dravet ...
Medical Xpress / AI could help predict your risk of breast cancer in the next four years
An artificial intelligence (AI) algorithm used to detect breast cancer in screening scans has been adapted into a risk score that estimates a woman's risk of developing breast cancer over the next four years, according to ...
Phys.org / Quantum dynamics show 'memory' depends on whether states or observables evolve
An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while retaining memory from ...
Phys.org / Leopards adapted to South Africa's Cape so successfully that they're genetically unique
Animals of the same species don't always look the same. From birds with different beak shapes to mammals that vary in size or color, populations living in different places can often look very different.
Medical Xpress / Time changes still frustrate Americans, and the fall shift appears to linger longer
Individuals have a more negative reaction to the societal time change to Standard Time (ST) in the fall than to Daylight Saving Time (DST) in the spring, according to a study published in the open-access journal PLOS One. ...
Phys.org / Late scientist's notebooks help finish study of rare 55-million-year-old tarpon fossil
Recently-revealed notebooks belonging to a late paleontologist contain the missing information needed to help researchers finish their study of a remarkable fossil discovered nearly three decades ago.
Phys.org / The forest is our pantry: Alaska national forests support abundant wild foods
Rural communities bordering the Tongass National Forest harvest more than 4.5 million pounds of wild food per year, including 100 different species that our public lands help support. Just how much food is this? An average ...
Phys.org / Vocal analysis and AI uncover two new Amazon antbirds in five-species complex
Scientists have discovered that a widely recognized Amazonian antbird is not one, but five distinct species—including two completely new to science. This revelation of hidden biodiversity was achieved by integrating artificial ...
Phys.org / Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology
After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...
Phys.org / Antibacterial coatings with short-term effect may fail over longer periods of time
Researchers from the Institute of Physics and the Institute of Molecular and Cell Biology of the University of Tartu have shown in a recently published study that antibacterial coatings which initially appear highly effective ...
