Phys.org / Ytterbium atomic clock could open a new window on fundamental physics
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Medical Xpress / A new AI model could help doctors detect lung cancer earlier
Lung cancer remains the leading cause of cancer-related deaths worldwide, accounting for nearly one in five cancer deaths—around 1.8 million lives lost each year. One of the main reasons is late diagnosis: in its early stages, ...
Phys.org / Origins of Earth's most powerful ocean current revealed
It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current rushes around the southern continent unhindered by land masses and is therefore a fundamental component ...
Tech Xplore / How electric cars could help tropical cities run on solar
In tropical cities, afternoon thunderstorms can plunge entire neighborhoods into brief moments of darkness. When civil engineer Markus Schläpfer moved to Singapore a decade ago, he recognized these thunderstorms as an emerging ...
Medical Xpress / MRI technique enables long-term tracking of transplanted stem cell-derived heart cells
Researchers at the Institute of Biomedical Engineering at the University of Toronto have demonstrated a new way to monitor transplanted stem-cell-derived heart cells using magnetic resonance imaging (MRI). The method allows ...
Tech Xplore / Bio-inspired structural design improves impact resistance and energy absorption
The delicate butterfly served as the inspiration for a new lightweight lattice structure that also boasts enhanced mechanical strength, impact resistance, and energy absorption capability through advanced structural design. ...
Tech Xplore / New memristor design uses built-in oxygen gradient to bring stability to reinforcement learning
In a recent study published in Nature Communications, researchers created a memristor that uses a built-in oxygen gradient to produce slow, stable conductance changes, enabling a reinforcement learning (RL) algorithm to learn ...
Phys.org / Global trade in wild birds is poorly monitored: The risks to wildlife, ecosystems and human health
Birds have, for centuries, been captured from the wild to be kept in cages—valued for their looks, songs and ability to imitate sounds. Data compiled by the Convention on International Trade in Endangered Species (CITES), ...
Phys.org / Can serendipity be harnessed? Reflecting on unplanned outcomes offers benefits
Superglue, penicillin, X-rays, the pacemaker: All are examples of "happy accidents"—inventions by individuals trying to do one thing, and winding up with something superior to the original objective.
Medical Xpress / A single enzyme keeps neuroblastoma alive—how to shut it off
The tumor begins before birth. Somewhere in the developing fetus, neural crest cells that should have matured into adrenal tissue or sympathetic ganglia take a wrong turn, and a child is born harboring a malignancy that may ...
Medical Xpress / Blocking RNA 'cleanup' may expose hidden cancer antigens, boosting immunotherapy
A new method of making cancer cells more visible to the immune system could improve how well immunotherapy works against a range of different tumors, potentially leading to more effective treatment for patients, according ...
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
