Your challenge is to tell us the location of the satellite image and why it is interesting.

Many species didn’t have much sex for millions of years. They didn’t need it. The post Sex jumpstarted Earth’s animal biodiversity appeared first on Popular Science.

Picture sea ice in your mind. You probably imagine brilliant white, snow-covered floes floating on the surface of the ocean, home to penguins in the south of the globe or polar bears in the north.

The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has participated in a study published in the Journal of Archaeological Science: Reports on Sala Keimada, one of the rock art sanctuaries in Cueva Palomera, the main cave of the Ojo Guareña Karst Complex (Merindad de Sotoscueva, Burgos, Spain).

Ground squirrel droppings, preserved for millennia in the Yukon's deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed genetic information about an environment that no longer exists. It is among the oldest ancient DNA ever recovered and sequenced.

Rhodoliths may look like small rocks on the seafloor, but they are actually living algae that create habitats for marine life and contribute to long-term carbon storage. A new study found that the deeper, low-light waters off Japan's Tanegashima Island harbor a surprisingly distinct and diverse community of these living pink rocks, including four species completely new to science.

A drug once dismissed as ineffective suddenly worked—when scientists tested it under more realistic conditions that mimic the human body. In this surprising new discovery, Northwestern University scientists uncovered a hidden rule of drug behavior. A medicine's effectiveness can change dramatically depending on the conditions inside our cells.

Mature and old-growth forests are vital for biodiversity, carbon storage, cultural traditions and economic activity. But in Alaska and British Columbia, these rich resources have not been reliably mapped, leaving much unknown about what land is protected. Now, University of Oregon researchers are leading a comprehensive mapping effort that sheds light on the location, makeup and conservation status of old-growth forests across the region.

The director of 'Close Encounters' and 'ET', an original story, 'X-Files'-style conspiracy theories… 'Disclosure Day' is a welcome escape from the mega-franchises.

In 2028 Los Angeles will become the first city to hold the (modern) Olympic Games for a third time, following previous runs in 1932 and 1984.Continue ReadingCategory: Sports, Consumer Tech, TechnologyTags: Olympics, Infrastructure, Sports, public transportation, Transport, Logistics

A surprising gut-heart connection may help explain why sleep apnea increases the risk of cardiovascular disease. In mice, disabling a bile acid receptor called FXR sharply reduced plaque buildup, opening the door to potential new treatments based on gut microbes and their chemical signals.

The livestream begins at 3:30 p.m. (1930 GMT) on June 9.

The Sagrada Familia has been under construction for more than 140 years, but Lego's new replica should hopefully prove a little quicker to assemble. Featuring just over 12,000 pieces, it's Lego's largest set to date by piece count.Continue ReadingCategory: Architecture, EngineeringTags: Lego, Education, Toys, Sagrada Familia
