Waste separation and recycling are essential to achieving a circular economy and sustainable resource management; however, the long-term success of well-established recycling systems depends on the continued participation of local residents. This study examined how social capital, defined as social relationships characterized by trust, reciprocity and mutual support, is associated with waste separation behavior. The research is published in the Journal of Material Cycles and Waste Management.

A fresh excavation of the eastern deposit at Riparo Mochi, a rock shelter near today’s French–Italian border, has pushed back the timeline for when Ice Age hunter-gatherers from Spain first entered Italy.
Pulses of a pungent gas keep rising from the flank of the Red Planet’s biggest volcano, and scientists can’t explain them away yet. The finding, reported in Science Advances, hints that Mars could still harbor molten rock beneath its surface. It isn’t proof, though, and the researchers say so themselves. Earth has around 40 volcanoes erupting at any given moment, and Venus is generally thought to have lava-spewing mountains of its own. Mars, once blanketed in active volcanoes, has gone quiet, and nobody has seen definitive signs of eruptions there. But a quiet planet is not necessarily a geologically dead…
Webb’s measurements of metal-rich gas offer clues to the processes that fuel our galaxy’s supermassive black hole, which consumes material more slowly than others. The gas circling the Milky Way’s central black hole is rich in metals, probably supplied by stars that exploded and released material into its surroundings over time. Researchers at McGill University’s […]
Users can now interact with Meta’s AI assistant through voice calls, text messages, or dictation on their Apple Watch.
Finally, a use of the AI surveillance panopticon we can all agree on — maybe. As TechSpot recently highlighted, school buses around the country are now carrying small AI-powered cameras to catch drivers who ignore those little fold-out stop signs they deploy when kids are getting on and off the vehicle. In theory, the practice makes roads a little less perilous to pedestrians, though to be fair, there’re still questions over its efficacy and privacy concerns. One company developing these instant-karma machines, BusPatrol, has already equipped around 35,000 buses with its cameras across 24 states. Once it spots an offending…
Thousands of years ago, parts of the Arabian Peninsula were filled with freshwater lakes and wildlife. Yet surprisingly few traces of human activity have been found there. A new study suggests the reason wasn’t a lack of water, but something much less obvious: the right kind of stone. Today, much of southern Arabia is covered by enormous stretches of desert. But the landscape looked very different during wetter periods, when lakes and vegetation spread across areas that are now almost completely dry. These conditions might seem ideal for prehistoric communities looking for places to live and find food. So why…
Theft is almost universally considered an exploitative behavior. The conventional view underlying judicial systems is that the act of taking resources from others without offering compensation stems from moral and personal failings. As a result, these systems rely on the assumption that the threat or imposition of punishment will motivate criminal offenders to adjust their future behavior. Yet the outcome is not always success.
Most of us spend much of our day staring at organic light-emitting diodes, or OLEDs, which convert electricity into light to produce the colorful displays on smartphones, computer monitors and televisions. Although metal-free light-emitting materials that produce all colors are in demand, it has been difficult to make ones that efficiently emit orange-to-red light. Now, researchers led by the University of Osaka have shown that such materials do not need to be held in a rigid shape to work well: flexible molecules that can change shape can also emit orange-to-red light.
