The moment I meet Horst Schmidt-Böcking outside the Bockenheimer Warte subway stop just north of the downtown area of Frankfurt, Germany, I know I have come to the right place. After my “Hi, thank you for meeting me,” his very first words are “I love Otto Stern.” My trip on this prepandemic morning in November … Read more

Mars helicopter Ingenuity aces 19th flight after historic Red Planet weather delay

by

The dust storm couldn’t keep NASA’s Mars helicopter Ingenuity grounded forever. The 4-pound (1.8 kilograms) Ingenuity aced a 100-second sortie on Tuesday (Feb. 8), its 19th Red Planet flight overall but its first since Dec. 15. The flight had originally been targeted for Jan. 5. But on New Year’s Day, a big dust storm kicked … Read more

These sponges survive the deep sea by feeding on remains of long-dead animals | Science

by

It can be hard to find food in the central Arctic Ocean. The water is frigid and the surface is blanketed in ice, making it nearly impossible for the tiny organisms that power many marine food chains to photosynthesize. Now, researchers have unraveled how a gigantic, newly discovered sponge garden gets around the lack of … Read more

Can scientists repair their relationship with Native people as they probe the past? | Science

by

How and when people first set foot in the Americas is one of the enduring mysteries of human history. Most archaeologists now agree people lived in the Americas before Clovis-style tools—once thought to be linked to the first Americans—appeared about 13,000 years ago. Last year, for example, researchers reported human footprints in White Sands National … Read more

NASA picks Lockheed Martin to build rocket to carry Mars samples back to Earth

by

NASA’s Mars sample-return plan continues to come together. The agency announced on Monday (Feb. 7) that it has selected the aerospace company Lockheed Martin to build the Mars Ascent Vehicle (MAV), a small rocket that will launch pristine Red Planet samples back toward Earth a decade or so from now. “Committing to the Mars Ascent … Read more

Arctic Sponges Survive Dark, Hostile Conditions by Feasting on The Extinct

by

The bottom of the Arctic Ocean, below the permanent sea ice, is not a friendly place for life. Down there in the cold dark, nutrients and vegetation are sparse; it’s expected that any life that does manage to eke out an existence under these conditions would be likewise thin on the ground.   Scientists were … Read more

Surprise Fossil-Munching Sponges Found in Arctic Seafloor Wasteland

by

Entombed below a thick layer of sea ice year-round and nearly devoid of nutrients, the central Arctic Ocean is a frigid wasteland where few creatures are capable of surviving. That is why researchers at Germany’s Alfred Wegener Institute (AWI) and their colleagues were so surprised to spot a thriving community of velvety deep-sea sponges below … Read more
