The Planet (on, and off)

A study published last week in the scientific journal Nature Energy studied the effects of traffic and travel time in a city when micromobility options like electric scooters and e-bikes are banned. The results documented exactly how much traffic increased as a result of people switching back to personal cars Read more…

A team of researchers has detected a trio of near-Earth asteroids in the inner solar system, one of which is the largest found since 2014 that poses a potential risk to the planet. The asteroids remained undetected until now because they occupy a region of the sky hidden by the Read more…

The Jerusalem Post reports that “Certain star clusters do not seem to be following current understandings of Isaac Newton’s laws of gravity, according to new research published on Wednesday.” (Specifically open star clusters, formed when thousands of stars are born in a gas cloud within a short time period.) The Read more…

“NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in the planet’s dust-producing deserts — information that will advance our understanding of airborne dust’s effects on climate,” NASA announced this week. “But EMIT has demonstrated another crucial capability: detecting the presence of methane, Read more…

A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs. Strange as it sounds, the lighter-than-air element that gives balloons their buoyancy also powers the vital medical diagnostic machines. An MRI can’t function without some 2,000 liters of ultra-cold liquid Read more…

China plans to break its own record for the world’s largest wind farm by constructing a new one before 2025 that could power more than 13 million homes.
