The Apollo astronauts didn’t know what they’d find when they explored the surface of the moon, but they certainly didn’t expect to see drifts of tiny, bright orange glass beads glistening among the otherwise monochrome piles of rocks and dust.
The beads, each less than 1 mm across, formed some 3.3 to 3.6 billion years ago during volcanic eruptions on the surface of the then-young satellite. “They’re some of the most amazing extraterrestrial samples we have,” said Ryan Ogliore, an associate professor of physics in Arts & Sciences at Washington University in St. Louis, home to a large repository of lunar samples that were returned to Earth. “The beads are tiny, pristine capsules of the lunar interior.”
Using a variety of microscopic analysis techniques not available when the Apollo astronauts first returned samples from the moon, Ogliore and a team of researchers have been able to take a close look at the microscopic mineral deposits on the outside of lunar beads. The unprecedented view of the ancient lunar artifacts was published in Icarus. The investigation was led by Thomas Williams, Stephen Parman and Alberto Saal from Brown University.
On planet Earth, fire is usually a transient phenomenon—even the strongest of wildfires will eventually succumb to human and/or meteorological intervention. But the same can’t be said for the Darvaza gas crater in Turkmenistan, known colloquially as the “Gates of Hell.” This natural gas field has been burning continuously for decades thanks to its steady supply of seeping methane, and in that time, this devilish pit has become one of the country’s most popular tourist attractions despite its location in the middle of the Karakum desert, roughly 160 miles north of the capital city of Ashgabat.
Turkmenistan’s authoritarian leader, Gurbanguly Berdymukhamedov, has previously stated that he wants to snuff out the Gates of Hell once and for all (though the latest pronouncement came years after he reportedly went off-roading around the crater). Now, a new report suggests those efforts may be bearing fruit. Last Thursday, officials in Turkmenistan said that gas being emitted from the pit has diminished three-fold, though the Agence France-Presse (AFP) reports that no timeframe for this gaseous decrease was provided. This news is in line with previous reports last year that satellite observations of the Gates of Hell showed a 50 percent decline in emissions.
Mitigating climate change is prompting all manner of changes: from the rapid transition to EVs to an explosion in renewables capacity. But these changes must be underpinned by a transformation of electricity grids to accommodate an energy sector that looks very different to how it does today.
Deep in the swamps of the American Southeast stands a quiet giant: the bald cypress (Taxodium distichum). These majestic trees, with their knobby “knees” and towering trunks, are more than just swamp dwellers—they’re some of the oldest living organisms in Eastern North America. Some have been around for more than 2,500 years, quietly thriving in nutrient-poor, flooded forests where most other trees would wither.
But life isn’t easy for these ancient trees. They’re under siege from a variety of threats: rising seas, insect infestations, wildfires and increasingly erratic weather patterns. Unlike most animals, trees generally don’t die of old age—they succumb to the stresses around them.
A study by Florida Atlantic University, in collaboration with Lynn University, the University of Georgia, the Georgia Department of Natural Resources, and the Georgia Museum of Natural History, reveals how dramatic shifts in climate can have long-lasting effects on even the toughest, most iconic trees—and offers a glimpse into the powerful forces that shape our natural world.
Physicists at the University of Oxford have set a new global benchmark for the accuracy of controlling a single quantum bit, achieving the lowest-ever error rate for a quantum logic operation—just 0.000015%, or one error in 6.7 million operations. This record-breaking result represents nearly an order of magnitude improvement over the previous benchmark, set by the same research group a decade ago.
To put the result in perspective: a person is more likely to be struck by lightning in a given year (1 in 1.2 million) than for one of Oxford’s quantum logic gates to make a mistake.
The findings, to be published in Physical Review Letters, are a major advance towards having robust and useful quantum computers.
With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico.
The team was able to sample the ocean right after the storm passed and found that the storms churn the ocean so powerfully and deeply—up to thousands of meters—that nutrient-rich, cold water is brought to the surface.
The resulting phytoplankton blooms—visible in satellite imagery taken from space—are a feast for bacteria, zooplankton, small fish, and filter-feeding animals such as shellfish and baleen whales.
Scientists edge closer to unleashing virtually unlimited power source — here’s when it could finally go live

This high energy output could vastly improve the world’s sustainability. With fusion, energy would be near-limitless and thus easily accessible and substantially more affordable. People could enjoy lower utility bills and consistent, reliable energy.
Watch now: How bad is a gas stove for your home’s indoor air quality?
The innovative reactor would help slow down climate change and lead to a cleaner, cooler future, while helping people save money and access clean energy. Reducing energy pollution will benefit every human, reducing the health hazards of breathing polluted air or drinking contaminated water.
Seasonality shapes much of life on Earth. Most species, including humans, have synchronized their own rhythms with those of the Earth’s seasons.
Plant growth cycles, the migration of billions of animals, and even aspects of human culture—from harvest rituals to Japanese cherry blossom viewings—are dictated by these dominant rhythms.
However, climate change and many other human impacts are altering Earth’s cycles. While humans can adapt their behavior by shifting the timing of crop harvests or Indigenous fire-burning practices, species are less able to adapt through evolution or range shifts.
