Dimming the sun could save corals from bleaching and hurricanes

Dimming the sun could save corals from bleaching and hurricanes

Time for artificial planet coolers? A cooling “sunshade” for the planet could reduce harmful coral bleaching and the number of hurricanes, which damage reefs. With the effects of climate change becoming increasingly apparent, the idea of squirting a cloud of sulphate aerosols into the upper atmosphere is being investigated by several groups of scientists. This would scatter some of the sun’s rays back into space, reducing the rate at which the Earth is warming.

New tyrannosaur fossil is most complete found in Southwestern US

New tyrannosaur fossil is most complete found in Southwestern US

A remarkable new fossilized skeleton of a tyrannosaur discovered in the Bureau of Land Management’s Grand Staircase-Escalante National Monument (GSENM) in southern Utah was airlifted by helicopter Sunday, Oct 15, from a remote field site, and delivered to the Natural History Museum of Utah where it will be uncovered, prepared, and studied. The fossil is approximately 76 million years old and is most likely an individual of the species Teratophoneus curriei, one of Utah’s ferocious tyrannosaurs that walked western North America between 66 and 90 million years ago during the Late Cretaceous Period.

Scientists investigate why crows are so playful

Scientists investigate why crows are so playful

Crows share an interesting set of behaviors with humans: they like to play, and they often use tools. We know that humans play to learn. When toddlers knock over a pile of blocks, they're developing the ability to build and measure objects in the real world. The question is, do crows play for the same reason? An international team of cognitive scientists played with some crows to find out. What they discovered gives us a new understanding of crow consciousness, but it still leaves a lot of questions unanswered.

It’s Not Crazy to Dream of a World Without Fossil Fuels

It's Not Crazy to Dream of a World Without Fossil Fuels

Several dozen academics, diplomats, and energy researchers gathered earlier this year in Berlin to embark on a fascinating thought experiment. They began with the assumption that a worldwide transition from fossil fuels to renewables is all but inevitable—a future that is not guaranteed, but hardly implausible either, despite the current domination of oil and gas. Then they imagined what that future would look like, not just in terms of the energy economy but in terms of society as a whole. Oil, coal, and gas have shaped and structured our political and economic system for well over a century.

FDA approves a game-changing treatment for blood cancer

FDA approves a game-changing treatment for blood cancer

he Food and Drug Administration on Wednesday approved a promising new treatment for a particularly deadly form of cancer, bringing hope to desperate patients while rekindling a global conversation about the escalating cost of new therapies. The treatment, made by Gilead Sciences, is made by extracting patients’ white blood cells and re-engineering them to home in on tumors. Called a CAR-T, the one-time treatment has shown unprecedented results for patients with dire diagnoses.
