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 ...
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 / 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 ...
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 / 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 / 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 ...
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.
Phys.org / After commercial whaling nearly erased them, blue and fin whales are slowly reclaiming the southeast Atlantic
More than 40 years after the end of commercial whaling, new research reveals a recent increase in sightings of the world's two largest whale species in the southeastern Atlantic. The findings, published in the African Journal ...
Medical Xpress / FDA approves first self-balancing, personal exoskeleton
The U.S. Food and Drug Administration has cleared Eve (Wandercraft), the first self-balancing personal exoskeleton for eligible adult wheelchair users living with spinal cord injury.
Phys.org / One-off campus programs fall short on preventing sexual violence, review finds
A recent National Student Safety Survey found that one in six students attending Australian universities had been sexually harassed and one in 20 had been sexually assaulted since starting university.
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 ...
Medical Xpress / Could saunas and ice baths affect male fertility? Here's what the evidence says
The internet's obsession with "maxxing" has turned almost every aspect of self-improvement into a trend.
