(University of Exeter) Eminent scientists warn that key ecosystems around Australia and Antarctica are collapsing, and propose a three-step framework to combat irreversible global damage.
To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres.
(University of Oregon) Friction caused by dry Martian dust particles making contact with each other may produce electrical discharge at the surface and in the planet’s atmosphere, according University of Oregon researchers. However, such sparks are likely to be small and pose little danger to robotic or human missions to the red planet, they report in the journal Icarus.
In a huge moment for space exploration, the American space agency will today attempt to land a new rover on the surface of Mars. The six-wheeled robot, named Perseverance, will be the first NASA mission since the 1970s to search directly for signs of ancient life on the Red Planet. Powered by plutonium, this is […]

The optimal level of risk is never zero. Otherwise, nobody would ever get up in the morning. But even staying in bed is risky (people die in their sleep). When you drive from home to work your risk of dying…
Taking a moment away from your work to stretch out your mind can be a great way to manage stress, and these NASA videos of our Sun, Moon, and Earth are perfect ways to do so. Buried in our screens, buried under a curtain of artificial light, humans can lose connection with an intangible part […]

(University of Colorado at Boulder) The golden-mantled ground squirrel is one of the most photographed animals in the Rocky Mountains. It’s also joining many other species of rodents and shrews in Colorado that are making an ominous trek: They’re climbing uphill to escape from climate change.
In the early months of the pandemic, as travel ground to a halt, news outlets and random Twitter users breathlessly pointed out that smog was clearing up, animals were roaming the streets, and even Venice’s canals were looking better than ever. Many of…
Neuroscientists have experimented on mice to identify the brain region that functions beyond sensory encoding and motor encoding, potentially opening up new directions to studying the cellular and circuit mechanisms of sensory-motor transformations. The researchers report a cortical region traditionally defined as whisker motor cortex in mice is most directly related to the transformation process.
Wildfires burned more than 10 million acres in the United States during the 2020 season. It was the worst season on record.
