Chinese prefer Europeans to Americans, but feeling isn't mutual, says study
Federally funded scientists who work with potentially harmful bacteria, viruses, and other agents could soon face a major expansion of U.S. government oversight. An expert group last week recommended broadening rules that require universities and funding agencies to determine whether proposed studies count as dual-use research—work that carries the risk of intentionally or accidentally...
Warmer climate may drive fungi to be more dangerous to our health
People in China have more favorable opinions of Europeans than Americans, but the feeling is not mutual, according to a new study from researchers at Rice University, the National University of Singapore and the University of British Columbia.
Predicting human group sizes with physics
The world is filled with tiny creatures that find us delicious. Bacteria and viruses are the obvious bad guys, drivers of deadly global pandemics and annoying infections. But the pathogens we haven't had to reckon with as much—yet—are the fungi.
How to reduce the temptation to cheat: Empathy
Only by knowing the average number of friends each person has, scientists at Complexity Science Hub (CSH) were able to predict the group sizes of people in a computer game. For this purpose, they modeled the formation of social groups on an example from physics, namely the self-organization of particles with spin.

Solid material that 'upconverts' visible light photons to UV light photons could change how we utilize sunlight
For more than 140 years, fishers in southeastern Brazil have formed an
unusual partnership with local dolphins
. In the small coastal city of Laguna, men wait for the marine mammals to swim up a narrow lagoon, herding silvery mullet from the Atlantic Ocean into shallower waters. As soon as the fishers spot a dolphin slapping its tail, lifting its head, and diving deeply,...
Fishing in synchrony brings mutual benefits for dolphins and people in Brazil, research shows
The importance of solar power as a renewable energy resource is increasing. Sunlight contains high-energy UV light with a wavelength shorter than 400 nm, which can be broadly used, for example, for photopolymerization to form a resin and activation of photocatalysts to drive reactions that generate green hydrogen or useful hydrocarbons (fuels, sugars, olefins, etc.). The latter of these is often...
Researchers uncover dynamics behind protein crucial in breast cancer
By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice.

Inequality in access to basic services is a major problem in sub-Saharan Africa—but progress is happening
Resonant optical phenomena in metals and dielectrics have profound applications in many fields. The nanoscale confinement allows for unpreceded control of light-matter interaction at surfaces and interfaces, manipulating and controlling the light flow. Resonant phenomena are usually associated with radiative and intrinsic loss channels, which are detrimental in many systems. Metals show strong...
Electrospun nanomaterial offers great protection against electromagnetic interference
Economic activity and development are unevenly distributed across regions of the world and within any country. In other words, where someone lives can determine their economic and social well-being.
Schoolkids lost third of a year's learning to pandemic: study
Engineers have employed "electrospinning," a new technique of manufacturing nanomaterials, to produce a novel fabric that offers high performance protection against electromagnetic interference, a phenomenon that can result in electronic device malfunction and at high levels of exposure can harm human health.
Molecular clouds extend their lives by constantly reassembling themselves, say astronomers
School-aged students lost more than a third of a year's worth of learning early on in the pandemic and have still not caught up, posing "a real problem for this generation," researchers warned on Monday.
How a novel class of sulfonamides potently blocks malaria transmission
Astronomers have recently discovered that giant clouds of molecular hydrogen, the birthplace of stars, can live for tens of millions of years despite the facts that individual molecules are constantly getting destroyed and reassembled. This new research helps place a crucial piece of understanding in our overall picture of how stars are born.
Political orientation could be predicted by differences in brain activation and synchronization
Malaria is a devastating disease, with 247 million cases and 619,000 deaths reported in 2021 alone. Malaria causes fever and a flu-like illness that occurs when people are infected with the parasite Plasmodium falciparum, which is spread by mosquitoes. Drugs to treat malaria symptoms and insecticides to kill malaria-spreading mosquitoes have improved in recent decades, but the parasite and the...
New monovalent anion permselective membranes for high-efficient mono-/di-valent anion separation
A first-of-its-kind study scanned the brains of dozens of politically involved participants while they watched campaign-ads and speeches by parties from both ends of the political spectrum, just before one of the last rounds of elections. The participants, half right-wing and half left-wing, were scanned using magnetic resonance imaging (fMRI), a method that measures brain activation.
Primates colonised the Arctic during a period of ancient global warming—their fate offers a lesson
Monovalent anion perm-selective membranes (MAPMs) combined with electrodialysis can simultaneously realize the efficient separation of mono-/di-valent anions and the concentration of monovalent salt. However, their applications in practical industrial scenarios are limited due to the low anion selectivity of commercial MAPMs, especially the poor alkali stability.
Two new species of prehistoric primate were recently identified by scientists studying fossils from Canada's Ellesmere Island in the high Arctic. The primates are closely related and likely originated from a single colonization event, following which they split into two species: Ignacius dawsonae and Ignacius mckennai.
