Medical Xpress / Maternal genetic factors may reveal why pregnancy loss is so common
By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than half of human conceptions survive to birth. The research uncovered the strongest evidence yet for ...
Phys.org / ChatGPT found to reflect and intensify existing global social disparities
New research from the Oxford Internet Institute at the University of Oxford, and the University of Kentucky, finds that ChatGPT systematically favors wealthier, Western regions in response to questions ranging from "Where ...
Medical Xpress / Super-enhancers in cancer cells trigger DNA breaks and error-prone repair cycles
A new study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most powerful genetic "on switches" in cancer cells, called super-enhancers, drive unusually intense gene ...
Medical Xpress / People with 'binge-watching addiction' are more likely to be lonely, study finds
While many people binge-watch their favorite shows, binge-watching addiction is associated with loneliness, according to a study published in PLOS One by Xiaofan Yue and Xin Cui from Huangshan University in China.
Phys.org / Strategic sex: Alaska's beluga whales swap mates for long-term survival
In the icy waters of Alaska's Bristol Bay, a new study reveals how a small population of beluga whales (Delphinapterus leucas) survive the long haul through a surprising strategy: they mate with multiple partners over several ...
Phys.org / Engineered nanobodies improve respiratory defenses in preclinical study
In a multi-institutional study published today in Nature Nanotechnology, researchers from The University of Texas MD Anderson Cancer Center reported that engineered bispecific nanobodies successfully strengthened mucosal ...
Phys.org / How shifting tectonic plates drove Earth's climate swings
Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds.
Phys.org / New class of strong magnets uses earth-abundant elements, avoids rare-earth metals
Georgetown University researchers have discovered a new class of strong magnets that do not rely on rare-earth or precious metals—a breakthrough that could significantly advance clean energy technologies and consumer electronics ...
Phys.org / New cryogenic vacuum chamber cuts noise for quantum ion trapping
Even very slight environmental noise, such as microscopic vibrations or magnetic field fluctuations a hundred times smaller than Earth's magnetic field, can be catastrophic for quantum computing experiments with trapped ions.
Medical Xpress / Tumor cells steal immune mitochondria to aid lymph node spread
Stanford University-led researchers report that tumor cells hijack mitochondria from immune cells, reducing anti-tumor immune function and activating cGAS-STING and type I interferon signaling that promotes lymph node metastasis.
Phys.org / Beyond chemistry: How mechanical forces shape brain wiring
During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain by following precise ...
Medical Xpress / LLMs can identify major depressive disorder via voice note recordings
A new medical large language model (LLM) achieved over 91% accuracy in identifying female participants diagnosed with major depressive disorder after analyzing a short WhatsApp audio recording where participants described ...
