Evidence is growing that sperm carries marks of a father’s life experiences, influencing traits in offspring. On a bright afternoon in Jiangsu, China, Xin Yin is playing personal trainer to some mice. One by one, he sets the rodents on a miniature treadmill that starts slow and gradually speeds…
Fortunately, it happened early in the morning, so nobody was around. At 5:26 am local time on August 10, 2025, a massive wedge of rock with a volume of at least 63.5 million cubic meters detached from a mountain above Alaska’s Tracy Arm fjord. The falling rock plummeted into…
It’s hard to mix electronic manufacturing and flexible geometry. To get quantum computing to work, we will ultimately need lots of high-quality qubits, which we can tie together into groups of error-corrected logical qubits. Companies are taking distinct approaches to get there, but you can think of them as…
Testing shows rotor blades won’t disintegrate when they spin at supersonic speed. A little more than three years since NASA’s Ingenuity helicopter ended its pioneering mission at Mars, engineers at the Jet Propulsion Laboratory in California are designing next-generation Martian rotorcraft to carry heavier payloads longer distances through the planet’s…
Three served on the HMS Erebus; the fourth was Petty Officer Harry Peglar of the HMS Terror. Archaeologists continue to use DNA analysis to identify the recovered remains of the doomed crew members of Captain Sir John S. Franklin’s 1846 Arctic expedition to cross the Northwest Passage. They can…
As pollen season worsens, allergies compound with other climate health hazards. It’s not in your head. Climate change is contributing to longer and more severe pollen seasons across the Northern Hemisphere. Dr. Neelima Tummala, an ear, nose, and throat doctor at NYU Langone Health, said her patients tell her…
As social media splinters, how can we keep the new online spaces from devolving into toxic pits of despair? Last fall, we featured an extensive interview with Petter Törnberg of the University of Amsterdam, who studies the underlying mechanisms of social media that give rise to its worst aspects:…
Vandenberg Space Force Base in California is set to become SpaceX’s busiest launch site—for now. It is far too soon to mention retirement, but astute observers of the space industry have noticed SpaceX’s workhorse Falcon 9 rocket is not launching as often as it used to. The decline is…
NASA is serious about taking more shots on goal, but some of them need to start landing. NASA’s goal of reaching the Moon’s surface as many as 21 times over the next two and a half years will require an overhaul of the agency’s approach to buying lunar landers…
Onshore wind development in the United States is being brought to a standstill. The Trump administration has brought US onshore wind development to a halt citing national security concerns, representing a major escalation in the president’s crusade against renewable energy. Approvals for about 165 onshore wind projects on private…
