Phys.org / Surrounded by stardust: Antarctic ice cores confirm Earth is accumulating iron-60 from local interstellar cloud
Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron ...
Phys.org / When politics enter the picture, credentials take a back seat
Most Americans know what a real expert's credentials look like: relevant degree, years of experience, and respect from peers. The problem, according to a study recently published in Scientific Reports, is that none of it ...
Medical Xpress / Why teen health visits still lack privacy, even when most parents support it
While most parents say it's important for health care providers to speak privately with teens during checkups, far fewer are putting that belief into practice, according to a new national poll.
Phys.org / New spacecraft will watch Earth's shield take the hit as solar storms come roaring in
A joint European-Chinese spacecraft is set to blast off Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth's magnetic shield.
Medical Xpress / Longevity-linked APOE2 gene variant helps neurons repair DNA and resist aging
People who carry the APOE2 version of the apolipoprotein E gene are more likely to live to advanced age and are partly protected against Alzheimer's disease, but scientists have struggled to explain why. A new study from ...
Medical Xpress / Metabolic health emerges as key to brain and memory problems in bipolar disorder
While they share similar depressive and cognitive symptoms, the biological underpinnings of bipolar disorder and major depressive disorder are distinct. A novel study appearing in Biological Psychiatry: Cognitive Neuroscience ...
Phys.org / Fluorescent RNA sensor gets 10 times more sensitive for water safety
Water is largely tasteless to humans. But to the microbial world, it is anything but. Bacteria that live in contaminated environments have spent millions of years evolving exquisitely sensitive molecular detectors—proteins ...
Phys.org / Hidden cell networks emerge in 3D as new nanoscopy tracks living bridges
A new nanoscopy technique developed at The Australian National University (ANU) has uncovered hidden networks used for communication between cells, opening new ways to understand human diseases. Described in an article published ...
Medical Xpress / AI-driven wearable patches help identify undetected hormone disruption in unexplained infertility
Men and women who appear hormonally "normal" may still have undetected disruptions in the timing and coordination of their reproductive hormones that could impair fertility, according to research presented at the 28th European ...
Medical Xpress / Weight-loss drugs tied to lower death, recurrence risk after breast cancer
New research published in JAMA Network Open suggests that there is a positive association between GLP-1 agonists—drugs commonly used to treat obesity and diabetes—and better outcomes among breast cancer patients.
Phys.org / Falling space debris poses an escalating risk as spacecraft get stronger and more heat resistant
When it comes to space debris, what goes up is coming down more often—and not safely.
Medical Xpress / AI tool for radiotherapy can support the global effort to eliminate cervical cancer
An AI technology is effective at planning the delivery of life-saving radiotherapy for cervical cancer and prostate cancer, according to results from a large international trial led by researchers at University College London ...
