Why worms (and microbes) are catching on as a manure pollution solution
Anthony Agueda, a third-generation California dairy farmer, pulls a rake through a bed of dark, wet wood chips on his family’s land in Hickman, a tiny town in the state’s agricultural heartland. He reaches down with both hands and pulls up a clump of muck, turning it over to reve
The Download: worms fight pollution, and geoengineering faces reality
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Why worms (and microbes) are catching on as a manure pollution solution Anthony Agueda, a third-generation California dairy farmer, pulls a ra
SpaceX is on track for record-setting Starlink deployments
SpaceX is currently ahead of last year's record-setting pace for Starlink satellite deployments. SpaceX launched 1,589 Starlink satellites into low-Earth orbit in the first half of 2026, according to launch data compiled by Jonathan McDowell's satellite tracker, compared to 1,489
The US Approves the Launch of a Mirror Satellite That Can Reflect Sunlight and Illuminate
The FCC authorized Reflect Orbital to launch the mirror satellite Eärendil-1. “For optical astronomy, this poses an existential threat,” the European Southern Observatory said.
The first sunlight reflecting space mirror has been cleared for launch
Reflect Orbital has been given the green light to launch its first space mirror that aims to redirect sunlight down to Earth at night. The US Federal Communications Commission (FCC) has authorized the California-based startup to build and operate a single prototype satellite in l
Dead stars in our cosmic backyard: Astronomers spot four white dwarfs hiding under our nos
Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are all within 65 light-years of Earth, and one contains the
Most of the moon's water likely remains chemically bound in its deep interior
After decades of analyzing reams of lunar rocks back here on Earth, the canonical view of the moon was that it was anhydrous; that it had extraordinarily little water. That all began to change in 2009 with new data from NASA's Lunar Crater Observation and Sensing Satellite (LCROS
NASA’s Cold Atom Lab is creating one of the weirdest forms of matter in space
NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways. The experiments could unlock new discoveries about the universe while paving the way for powerful future tec
How long can plants survive on Earth? New model suggests up to 2 billion more years
Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has been increasing over epochs and eons by about 10% every bil
This four-winged dinosaur may have terrorized Earth's earliest birds
A newly discovered feathered dinosaur called Jian changmaensis may be the missing predator responsible for mysterious piles of crushed prehistoric bird bones in China. The four-winged glider, a close cousin of Velociraptor, helps reveal how early birds and their dinosaur relative
Oldest known asteroid impact on Earth dated to 3 billion years
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
