Understanding the wakes and vortices that jellyfish produce as they swim is crucial, according to Wu, et al. Particle image velocimetry (PIV) is a vital tool for studying flow phenomena and biomechanical propulsion. PIV essentially tracks tiny tracer particles suspended in water by illuminating them with laser light. The technique usually relies on hollow glass spheres, polystyrene beads, aluminum flakes, …

“We all are committed to evidence-based recommendations,” Robbie Goldstein, Massachusetts’ public health commissioner and a participant in the meetings, told the Globe Thursday. “It is not a question about, ‘Are we breaking from the federal government?’ It is, ‘How do we continue to do this thing that we’ve always done?’ which is to use science and evidence to drive our …

On August 20, 2025, Russia will launch the Bion-M No. 2 biosatellite atop a Soyuz-2.1b rocket from the Baikonur Cosmodrome in Kazakhstan, marking a key step in studying the effects of spaceflight on living organisms. As reported by Space.com, the spacecraft will carry 75 mice, over 1,000 fruit flies, and other biological specimens for a 30-day mission in space, exposing …

Self-lofting devices propelled by sunlight have been tested for the first time in near-vacuum conditions akin to those in Earth’s upper atmosphere, paving the way for a revolution in atmospheric science. The tiny, lightweight membranes — which are made of aluminum oxide and a layer of chromium — take advantage of a phenomenon known as photophoresis, which occurs when one …

A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality. Imagine a safe gamma ray laser that could eradicate cancer cells without damaging healthy tissue. Or a tool that could help determine if Stephen Hawking’s multiverse theory is real by revealing the fabric underlying the universe. …

Scientists often refer to the mesosphere as the “ignorosphere”—a region that’s too high for planes or weather balloons to explore, yet too low for satellites to probe. Despite our technological advances, we’ve yet to find a decent way to monitor this large stretch of air, which lies about 37 miles (60 kilometers) above the surface. But engineers are inching towards …

A four-legged robot tested under simulated Martian gravity jumps from wall to wall in a new video, demonstrating how future explorers could navigate terrain too challenging for today’s rovers. Designed for use in low-gravity environments like on the moon and Mars, the four-legged robot, named Olympus, uses “double” limbs with jointed knees and paw-like feet for agile movement. At the …

Manchester United fans have a favoured refrain, often given prominence during leaner times, one that ends with the view they’re “never ignored”. It is a maxim proving true this summer. On the back of their worst domestic showing in half a century, with no European football on the horizon, staff numbers being scythed and, just five months ago, an owner …

Relationship advice often centers on the idea of growing together to avoid drifting apart. But in the horror movie Together, growing apart isn’t an option for one couple. Alison Brie stars as Millie, a teacher who’s ready to take the next step in her relationship: marriage. Her partner of more than a decade, Tim, played by Dave Franco, is an …
