New research turns the Dunning-Kruger effect on its head: Rethinking the confident incompetent
Researchers at the University of Bath and The London School of Economics and Political Science (LSE) suggest that the celebrated Dunning-Kruger effect, often taken to mean the least competent people are the most overconfident, may actually be the wrong way around.
New research reveals mass shootings and suicide deaths share summer peaks
A new study has found that mass shootings and deaths by suicide in the United States share seasonal patterns, reaching their highest levels during summer months. Analyzing national data spanning 2014–2021, researchers observed consistent summertime peaks in both mass shootings and suicide deaths, suggesting that common environmental, behavioral or biological factors may contribute to seasonal fluctuations in these forms of violence.
Why Jupiter has several giant moons but Saturn has only Titan
Jupiter and Saturn are the two largest planets in the Solar System, and both are surrounded by enormous families of moons. Jupiter currently has more than 100 reported moons, while Saturn, which is also encircled by an extensive ring system, has more than 280.

The best way to save giant sequoias may be more fire
Two devastating wildfires that swept through California's Sierra Nevada in 2020 and 2021 killed thousands of giant sequoias. A new University of California, Davis study suggests the losses would have been far worse without prescribed burns.
Cutting out the noise: How horseshoe bats adapt their echolocation behavior in colonies
Imagine searching for a gemstone in a dark cave: You use a flashlight, looking for a rainbow-colored glint in the darkness. Now, imagine 10 other people in the cave with you, using different-colored flashlights at the same time. Suddenly, you can no longer tell which light is coming from your gemstone, which light is from another flashlight or which light is coming from a reflection off another unknown object. That is what echolocation with multiple, overlapping frequencies would be like. But now, imagine if every person in the cave were using a flashlight of the same color. The glint from the gemstone would be much easier to see.
Unraveling the climate behind the collapse of Bronze Age civilizations
The most severe droughts in the ancient Eastern Mediterranean arose when multiple natural climate cycles coincided, according to a new study from Stockholm University published in Science Advances. The findings shed new light on the climate conditions surrounding the Late Bronze Age collapse and may help improve understanding of future drought risks in a warming world.
Sweden’s hidden rare earth deposits could help break China’s grip
Swedish researchers are exploring how the country's mineral resources could support cleaner production of rare earth elements (REE) and the powerful magnets made from them. As part of the Sustainable materials and material flows research area, Martin Sahlberg is studying whether Sweden's deposits could become the foundation for a more sustainable magnet industry.
China’s Tianwen-1 captures interstellar comet 3I/ATLAS near Mars
China's Tianwen-1 spacecraft has photographed the interstellar object 3I/ATLAS as it passed near Mars. According to the China National Space Agency (CNSA), the orbiter used its high-resolution camera to capture the comet from about 30 million km (18.6 million mi) away.
