Phys.org / Collective intelligence: How to incentivize problem solving in groups
When a crowd gets something right, like guessing how many beans are in a jar, forecasting an election, or solving a difficult scientific problem, it's tempting to credit the sharpest individual in the room. But new research ...
Medical Xpress / Bioelectronic wristband offers continuous, objective, real-time stress monitoring
Researchers at the University of California, Irvine have developed a multimodal, bioelectronic wrist-worn device for objective, continuous, real-time monitoring of stress. The Smart Quantitative and Comprehensive Stress Assessor ...
Phys.org / South African San rock art reveals trance dances and initiation ceremonies
In a study published in Telestes, Dr. Joshua Kumbani and Dr. Margarita Díaz-Andreu categorized the various dance scenes depicted in South African rock art, drawing on ethnographic sources, published studies, and the comprehensive ...
Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon
The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...
Medical Xpress / Experimental immunotherapy clears harmful artery cells, reducing plaque in mice
Scientists have designed an immunotherapy that reduces plaque in the arteries of mice, presenting a possible new treatment strategy against heart disease. The antibody-based therapy could complement traditional methods of ...
Phys.org / Cleaner ship fuel changed clouds, but not their climate balance
To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created ...
Phys.org / Crosstalk inside cells helps pathogens evade drugs, study finds
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...
Phys.org / Refractive-index microscope measures a sample's optical properties with pinpoint accuracy
By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a sample with pinpoint accuracy. The original goal was to investigate biological samples on a molecular ...
Phys.org / Svalbard polar bears show improved fat reserves despite sea ice loss
The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations ...
Medical Xpress / Faster to trials? Low-dose THC plus celecoxib improved cognition in Alzheimer's model mice
In recent years, research into cannabis and its main psychoactive ingredient, Δ⁹-tetrahydrocannabinol (THC), has unearthed medical benefits including anti-inflammatory and neuroprotective properties. However, THC is also ...
Medical Xpress / Non-children's hospitals more commonly use imaging exposing children to ionizing radiation
Imaging modalities that expose children to ionizing radiation are used more frequently at non-children's hospitals compared with children's hospitals, according to a study published online Jan. 20 in the Journal of the American ...
Phys.org / Breakthrough laser technique holds quantum matter in stable packets
For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions within a grid of laser light.
