Phys.org / Neptune's tiny moons tell the story of Triton's destructive capture
Neptune's moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all ...
Phys.org / Tungsten may suffer more radiation damage in fusion reactors than expected
Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside ...
Medical Xpress / Brain activity reveals how people juggle changing goals in real time
Nature never sits still, and neither does anything living within it, since paths keep shifting as things move through the world. Decisions work the same way, changing shape as we go rather than settling once and for all. ...
Medical Xpress / High-speed microscopy reveals electrical activity across the brain
Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation ...
Phys.org / Shackled men in 2,600-year-old Greek mass graves were likely locals, archaeologists find
In 2016, archaeologists working at the Phaleron Burial Ground, part of the ancient Attica region, uncovered an astonishing sight: three mass graves dating to the 7th and 6th centuries BCE containing the skeletons of 79 adult ...
Phys.org / Nonrepeating photonic crystal may enable more tunable, reliable semiconductor lasers
Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are ...
Medical Xpress / Two devices in one: Metasurface could bring medical imaging to smaller sensors
Researchers have developed a technology for building more compact point-of-care medical imaging devices by creating a material that acts as two devices in one.
Tech Xplore / Helmholtz resonance powers miniature boats and ultrasonic flying robots
When air is blown across the neck of a bottle, it doesn't just produce a pleasant tone: it also demonstrates a phenomenon called Helmholtz resonance. This occurs when airflow passing across an opening causes air trapped inside ...
Phys.org / Four more belugas arrive at Chicago aquarium from shuttered Canadian theme park
Four more belugas have arrived at a Chicago aquarium as part of a plan to move Canada's last remaining captive whales from a shuttered theme park to aquariums in the United States and Spain.
Phys.org / Scientists simulating ant swarms find a 'first mover' can set the colony in motion
In ant colonies, a single ant can be the catalyst for a wave of mob activity, launching brief bursts of coordinated movement involving hundreds or even thousands of swarming workers, according to new simulations from New ...
Phys.org / Black-box technologies could undermine confidence in scientific findings
Scientists are increasingly relying on powerful data sources and tools that they often cannot fully understand, inspect or verify, according to a new study.
Phys.org / Minnesota iron ore could be key to sustainable and lower cost semiconductor
For the first time, researchers at the University of Minnesota Twin Cities have demonstrated that the low-purity iron ore prevalent in Minnesota can be used to create semiconductor-quality iron sulfide, also known as "fool's ...
