Scientists clarify origins of lunar metallic iron

Scientists clarify origins of lunar metallic iron

In a study published in Nature Astronomy, Profs. Shen Laiquan, Bai Haiyang, et al. from Prof. Wang Weihua's group at the Institute of Physics of the Chinese Academy of Sciences have clarified the respective effects of irradiation and impacts on the formation of metallic iron nanoparticles (npFe0).

Study finds motivation to compete is stronger with in-group members than with outsiders

Study finds motivation to compete is stronger with in-group members than with outsiders

Humans not only cooperate, but also compete more with in-group members than with out-group members and strangers, a new cross-country social-psychological study shows. This 'nasty neighbor effect' came as a complete surprise to the researchers, until they started delving into animal studies. The study is published in Science Advances.

LHCb investigates the rare Σ+→pμ+μ- decay

LHCb investigates the rare Σ+→pμ+μ- decay

The LHCb collaboration reported the observation of the hyperon Σ+→pμ+μ- rare decay at the XV International Conference on Beauty, Charm, Hyperons in Hadronic Interactions (BEACH 2024) in Charleston, South Carolina, U.S. A hyperon is a particle containing three quarks, like the proton and neutron, including one or more strange quarks.

Drowning in waste: Pollution hotspots in aquatic environments

Drowning in waste: Pollution hotspots in aquatic environments

An IIASA study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal. The work is published in the journal Nature Communications.

Astronomers discover two new Milky Way satellite galaxy candidates

Astronomers discover two new Milky Way satellite galaxy candidates

For years, astronomers have worried about how to explain why the Milky Way has fewer satellite galaxies than the standard dark matter model predicts. This is called the "missing satellites problem."

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

Soft, stretchy electrode simulates touch sensations using electrical signals

Soft, stretchy electrode simulates touch sensations using electrical signals

A team of researchers led by the University of California San Diego has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device, reported in a paper published in Science Robotics, represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations.
