Newfound genetic material may rev up methane cycling by soil microbes.
Bad news for coffee lovers. Global warming will limit our coffee consumption.
Global coffee prices are climbing and threatening to drive up costs at the breakfast table as the world’s biggest coffee producer, Brazil, faces one of its worst droughts in almost a century.
Prices for arabica coffee beans—the main variety produced in Brazil—hit their highest level since 2016 last month. New York-traded arabica futures have risen over 18% in the past three months to $1.51 a pound. London-traded robusta—a stronger-tasting variety favored in instant coffee—has risen over 30% in the past three months, to $1749 a metric ton, a two-year high.
Brazil’s farmers are girding for one of their biggest slumps in output in almost 20 years after months of drought left plants to wither. Brazil’s arabica crop cycles between one stronger year followed by a weaker year. Following a record harvest in 2020, 2021 was set to be a weaker year, but the drop is more severe than expected.
A team of astronomers has released new observations of nearby galaxies that resemble colorful cosmic fireworks. The images, obtained with the European Southern Observatory’s Very Large Telescope (ESO’s VLT), show different components of the galaxies in distinct colors, allowing astronomers to pinpoint the locations of young stars and the gas they warm up around them. By combining these new observations with data from the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, the team is helping shed new light on what triggers gas to form stars.
Astronomers know that stars are born in clouds of gas, but what sets off star formation, and how galaxies as a whole play into it, remains a mystery. To understand this process, a team of researchers has observed various nearby galaxies with powerful telescopes on the ground and in space, scanning the different galactic regions involved in stellar births.
Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they’ve found one. In a pair of papers, researchers at the University of Maryland’s (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride (or UTe2 for short) displays many of the hallmarks of a topological superconductor—a material that may unlock new ways to build quantum computers and other futuristic devices.
“Nature can be wicked,” says Johnpierre Paglione, a professor of physics at UMD, the director of QMC and senior author on one of the papers. “There could be other reasons we’re seeing all this wacky stuff, but honestly, in my career, I’ve never seen anything like it.”
All superconductors carry electrical currents without any resistance. It’s kind of their thing. The wiring behind your walls can’t rival this feat, which is one of many reasons that large coils of superconducting wires and not normal copper wires have been used in MRI machines and other scientific equipment for decades.
A dazzling new animation puts you aboard NASA’s robotic Juno spacecraft during its epic flybys last month of Jupiter and the huge moon Ganymede.
On June 7, Juno zoomed within just 645 miles (1038 kilometers) of Ganymede, the largest moon in the solar system. It was the closest a probe had gotten to the icy, heavily cratered world since May 2000, when NASA’s Galileo spacecraft flew by at a distance of about 620 miles (1000 km).
“The American Contractor Show” has shared its review of the installation of a Tesla Solar Roof. The show is a series of episodes featuring contracting and this episode took a deep dive into the Tesla Solar Roof installation process. Davide Silverstein and American Home Contractors demonstrated just what it takes to install a Tesla Solar Roof. The episode includes a step-by-step look at the installation process.
David Silverstein from American Home Contractors takes the host of the American Contractors Show, John Dye, on a walk-through of a Tesla Solar Roof installation.
Ark I is a self-sustaining space colony built to ensure humanity could survive disasters that make Earth uninhabitable such as nanoweapon disasters or particle accelerator mishaps.

Space may be pretty, but it’s dangerous. Astronauts face a much higher dose of ionizing radiation than us Earth-bound folks, and a new report says that NASA’s current guidelines and risk assessment methods are in serious need of an update.
On the surface of the Earth, protected by our extensive magnetic field and layers of thick atmosphere, we experience about 2–3 milliSieverts (mSv) of radiation exposure every year. Even that background level is enough to trigger the occasional cancer growth.
But astronauts, especially those hoping to go on upcoming long-term missions to the Moon and Mars, face a much greater risk due to the high-energy, ionizing radiation constantly soaking every cubic centimeter of space. To mitigate that risk, NASA currently implements a system based on “risk of exposure-induced death” (REID). The space agency estimates the exposure for each astronaut based on their sex, and if the REID exceeds 3%, their spacefaring careers are over.
The world’s first 3D-printed steel bridge has opened in Amsterdam. It was created by robotic arms using welding torches to deposit the structure of the bridge layer-by-layer using 4500 kilograms of stainless steel.
The first ever 3D-printed steel bridge has opened in Amsterdam, the Netherlands. It was created by robotic arms using welding torches to deposit the structure of the bridge layer by layer, and is made of 4500 kilograms of stainless steel.
The 12-metre-long MX3D Bridge was built by four commercially available industrial robots and took six months to print. The structure was transported to its location over the Oudezijds Achterburgwal canal in central Amsterdam last week and is now open to pedestrians and cyclists.
More than a dozen sensors attached to the bridge after the printing was completed will monitor strain, movement, vibration and temperature across the structure as people pass over it and the weather changes. This data will be fed into a digital model of the bridge.
