How do children learn to cooperate with others? A new cross-cultural study suggests that the answer depends less on universal rules and more on the social norms surrounding the child. [...]

A research team at The Hong Kong University of Science and Technology (HKUST) has developed an innovative urban food waste management framework by analyzing food waste data from 29 large cities worldwide, including Hong Kong, Beijing, and New York. The study shows that in cities with higher food waste moisture loads, such as Hong Kong, grinding food waste and diverting it into the sewage system is more effective than relying solely on landfilling. This approach can reduce overall greenhouse gas emissions by about 47% and lower total waste-management costs by about 11%. The research provides a new, quantitative basis for shaping food waste management strategies in cities around the globe. [...]

Utrecht University researchers Rodolfo Subert and Marjolein Dijkstra show in their latest study that complex three-dimensional networks in materials can emerge from nothing more than particle shape. In Nature Communications they describe how simple geometries, aided by entropy, can give rise to layers, networks and even spontaneous left- and right-handed twisting, which is a phenomenon previously linked mainly to highly complex molecules. [...]

Why did the rotisserie chicken cross the aisle—and end up in your shopping cart? Maybe you grabbed the container that was closest to you, or maybe you examined all of the chickens, checking dates and timestamps to see when they were cooked. Markets follow various display strategies for prepared foods, with many stores making older items more visible so they'll be sold before they spoil. However, a theoretical model created by an NJIT researcher suggests that customers prefer finding the freshest items at the front of the displays. [...]

Researchers have analyzed the stepwise hydration of prolinol, a molecule widely used as a catalyst and as a building block in chemical synthesis. The study shows that just a few water molecules can completely change the preferred structure of prolinol. The research is published in the Journal of the American Chemical Society. [...]

"There was no such thing as reproductive freedom for poor women in early modern Catholic Europe," states a recent article in the Journal of Modern History. The work examines several facets of "reproductive unfreedom" in the early modern period: namely, single motherhood, foundling hospitals, and wet nursing. [...]

Climate change is accelerating the arrival of warmer spring temperatures, and this phenomenon is affecting the conservation of many species. Now, a study published in the journal Global Change Biology reveals how a 2°C increase in temperature advances the reproductive process of the Mediterranean gorgonian, a species found in temperate waters that plays an important ecological role, providing structure and shelter and thus promoting biodiversity on the seabed. [...]

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build and coordinate the internal scaffolding needed to create a healthy egg. The research, published in the Journal of Cell Biology, details how two structural cellular systems work together to form developing egg cells. [...]

Access to trees and greenspaces is consistently low across English cities, according to a new study led by the University of Leeds. Researchers used a recognized three-part framework for measuring tree and greenspace access in urban neighborhoods in Leeds, Bradford, Wakefield, York, Manchester, Stoke-on-Trent and Plymouth, and found that at best, only 2% of buildings in any city region met all three components of the rule. [...]

When university students get to create real value for others, their motivation, self-confidence, and academic performance increase. This is shown by a new study published in The International Journal of Management Education that examines how university teachers use value creation pedagogy. "Value creation pedagogy can make education more meaningful and relevant for society—but it takes courage, time, and support to succeed," says Martin Lackéus, researcher at Chalmers University of Technology. [...]

Students with disabilities account for almost 15% of the K-12 student population in the United States. Yet they are often underrepresented in charter schools, which are publicly funded schools open to all students. While there are discussions about what type of school environment best supports these students, it is important to take a closer look at the difference in learning environments. [...]

For decades, astronomers have been watching WOH G64, an enormous heavyweight star in the Large Magellanic Cloud, a galaxy visible with the naked eye from the Southern Hemisphere. This star is more than 1,500 times larger than the sun and emitting over 100,000 times more energy. For a long time, red supergiant WOH G64 looked like a star steadily reaching the end of its life, shedding material and swelling in size as it began to run out of fuel. [...]

Using advanced computer simulations, researchers from the University of Rhode Island's Graduate School of Oceanography (GSO) have concluded how and why strong ocean currents modify surface waves. "Our primary finding is that hurricane-generated ocean currents can substantially reduce both the height and the dominant period of hurricane waves," said Isaac Ginis, URI professor of oceanography. "The magnitude of wave reduction depends strongly on how accurately ocean currents are predicted. This highlights the importance of using fully coupled wave-ocean models when forecasting hurricane waves." [...]

Astronomers from the University of Tokyo in Japan and elsewhere have employed the James Webb Space Telescope (JWST) to observe a distant ultraviolet-luminous galaxy known as CEERS2-588. Results of the observational campaign, published January 29 on the arXiv preprint server, shed more light on the nature and properties of this galaxy. [...]

From dyes to pharmaceuticals to emulsifiers—ethylamine (EA) is a versatile component used in many industries. The downside of EA is that its production is terribly complicated and energy intensive. However, it is not a simple task to simplify EA production in a way that can also be scaled up to industrial levels. Researchers at Tohoku University's WPI-AIMR may have found an answer to this problem. Rare earth Eu atoms were modified on Cu2O nanoneedles to produce a catalyst (Eu-Cu2O) that can increase the efficiency of the chemical reaction that produces EA. [...]

Recent storms washed away large sections of roads in the UK after sea defenses were damaged. For residents, it was a shock. But for coastal scientists, it was not unexpected. [...]

In a study published in American Antiquity, Dr. David Madsen and his colleagues address the proposition that the lower Lahontan drainage basin (LLDB), located in the Intermountain West, is "unique" for the use of caves and rock shelters as burial locations. They found that, compared with the Bonneville Basin (BB), the Great Basin's other major lake basin, the LLDB is not unique, and burial beyond it is neither rare nor uncommon. [...]

A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti at the University of Alabama in Huntsville suggests that an unseen clump of dark matter could be subtly tugging on nearby pulsars. If confirmed, the result could shed new light on the elusive nature of dark matter and how it is distributed throughout our galaxy. [...]
