    Apollo astronauts left trash, mementos and experiments on the moon

    Once on the moon, Apollo astronauts had two major goals: get themselves and the moon rocks home safe.

    To make space on the cramped lunar modules for the hundreds of kilograms of moon samples, the astronauts had to go full Marie Kondo. Anything that wasn’t essential for the ride home got tossed: cameras, hammocks, boots and trash. Downsizing also meant abandoning big stuff, like moon...

    Many fictional moon voyages preceded the Apollo landing

    From the beginning, the moon has been humankind’s perpetual nighttime companion.

    Accompanied by innumerable points of light, the moon’s luminous disk hovered overhead like a dim substitute for the sun, just with a shape not so constant. Rather the moon waxed and waned, diminishing to a barely discernible sliver before disappearing and then gradually restoring itself to fullness.

    It...

    A 100-hour MRI scan captured the most detailed look yet at a whole human brain

    Over 100 hours of scanning has yielded a 3-D picture of the whole human brain that’s more detailed than ever before. The new view, enabled by a powerful MRI, has the resolution potentially to spot objects that are smaller than 0.1 millimeters wide.

    “We haven’t seen an entire brain like this,” says electrical engineer Priti Balchandani of the Icahn School of Medicine at Mount Sinai in New...

    The highest-energy photons ever seen hail from the Crab Nebula

    Physicists have spotted the highest-energy light ever seen. It emanated from the roiling remains left behind when a star exploded.

    This light made its way to Earth from the Crab Nebula, a remnant of a stellar explosion, or supernova, about 6,500 light-years away in the Milky Way. The Tibet AS-gamma experiment caught multiple particles of light — or photons — from the nebula with energies...

    How NASA’s portable atomic clock could revolutionize space travel

    Traveling the solar system could one day be as easy as taking a bus to work. Scientists envision self-driving spaceships ferrying astronauts through deep space, and GPS-like systems guiding visitors across the terrains of other planets and moons. But for those futuristic navigation schemes, spacecraft and satellites would need to be equipped with clocks that keep time with extreme precision —...

    Is a long-dormant Russian volcano waking up? It’s complicated

    Seismic rumbles beneath a long-dormant volcano on Russia’s Kamchatka Peninsula could herald an imminent eruption, a team of scientists says. But other researchers say that the observed seismic activity could be related to already erupting volcanoes in the region.

    Fewer than 10,500 people live within 100 kilometers of the volcano, called Bolshaya Udina, making a catastrophic eruption that...

    Extra fingers, often seen as useless, can offer major dexterity advantages

    An extra finger can be incredibly handy. Two people born with six fingers per hand can tie their shoes, adroitly manage phones and play a complicated video game — all with a single hand, a study shows.

    These people’s superior dexterity, described June 3 in Nature Communications, suggests that instead of being seen as aberrations that ought to be surgically removed, extra fingers can...

  • 50 years ago, scientists wanted to build solar panels on the moon

    Solar power from moon to Earth —

    An almost unlimited supply of electricity could be generated on the moon’s surface by huge arrays of solar cells and beamed to Earth by laser. Sunlight falling on a crater … could produce from 10,000 to 100,000 megawatts of power. By comparison, a large hydroelectric dam on Earth produces about 100 megawatts. Solar cells would be more efficient on...

    AI can learn real-world skills from playing StarCraft and Minecraft

    Dario Wünsch was feeling confident. The 28-year-old from Leipzig, Germany, was about to become the first professional gamer to take on the artificial intelligence program AlphaStar in the rapid-fire video game StarCraft II. Wünsch had been professionally playing StarCraft II, in which competitors command alien fleets vying for territory, for nearly a decade. No way could he lose this five-...

    A gut bacteria transplant may not help you lose weight

    Changing your gut microbes may not help you lose belly fat.

    In a preliminary study, obese people got either capsules containing gut microbes from a lean person or placebo pills. Microbes from the lean donor took hold in the guts of the obese recipients. But early results suggest that the bacteria didn’t change the volunteers’ weight or levels of a hormone that helps signal fullness,...
