Cannabis is legal in some form or another in over half of US states. But federally, it’s illegal and has no accepted medical use. However, the Biden administration is moving to reclassify cannabis as a less dangerous drug under the Controlled Substances Act. Studying strictly controlled drugs like cannabis is a major challenge for scientists, becau…

For the first time, scientists have recorded how salps form chains and swim in corkscrews to reach the ocean’s surface each night. Also, a wind utility company in Wyoming is trying to make wind turbines more visible to birds by painting just one blade black. The Small Jelly Creatures That Link Up And Swim in Corkscrews Salps are small, transparent …

An early study found that electrical stimulation could improve hand and arm function in people with spinal cord injuries. Also, for thousands of years, Indigenous communities in Guatemala have used observations and mathematics to track astronomical events.

Did you know that almost all the wine we drink, no matter what color it is or where it’s produced, comes from a grape species called Vitis vinifera? But these grapes can’t survive the cold, harsh winters of Iowa, so researchers at Iowa State University are growing special varieties that can withstand a wider range of temperatures. Through this effo…

Rare earth elements are a group of 17 metals used in a wide range of things that make modern life possible, including batteries, magnets, LED light bulbs, phone screens, and catalytic converters. These elements are essential to a green economy because they are integral to many technologies designed to have low environmental impact. However, mining …

After the Big Bang, the universe expanded rapidly. And, once upon a time, conventional wisdom held that that expansion would eventually slow, dragged back inwards by the gravitational pull of all the matter in the universe. But in 1998, two groups studying supernovae discovered that not only was the universe continuing to expand, but that the expan…

The U.S. Preventive Services Task Force has updated its recommendations for breast cancer screening once again. The recommendations now stipulate that women and people assigned female at birth should begin getting mammograms at age 40, and continue every other year until age 74. The previous guidelines recommended beginning screening at age 50. The…

Upgrades to the power grid under a new rule could help accommodate an increasing renewable energy supply and meet data center demands. Also, extremely small particles might help scientists develop vaccines that are stable at room temperature and easier to administer. New Rule Sets Stage For Electric Grid Update The US electric grid is straining to …

The Field Museum has unveiled a new specimen of Archaeopteryx, a species that may hold the key to how ancient dinosaurs became modern birds. Also, a “green glacier” of trees and shrubs is sliding across the Great Plains, burying some of the most threatened habitat on the planet.
