Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can pull the planet ...
Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their ...
For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external ...
CSI may have spawned innumerable spinoffs, but it turns out you can't trust TV—or sniffer dogs. New research is questioning the scientific basis for the dogs' use by police, as well as aspects of bloodstain pattern analysis ...
A year or so after the full-scale invasion of Ukraine, the city of Murmansk in Russia's Arctic northwest marked its annual regional day with a celebration for children. Alongside the sons and daughters of Russian soldiers ...
Building with nature is an important concept in our coastal defense. After all, by harnessing natural processes, we are more resilient to sea level rise. A good understanding of these processes is therefore indispensable. ...
Deep space travel comes with a huge potential downside—radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. But what exactly does that mean, and is there any way to handle ...
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's ...
One of the hardest challenges in wildlife conservation arises when the habitat of a species in need of protection overlaps with land used by humans. Wolves and bears can kill livestock, elephants can damage homes and other ...
Heat shields are one of the most important parts of any spacecraft that intends to enter an atmosphere. And the material they are made of is critical. Improving them has been a challenge, though, as researchers typically ...
