The body's own brake on inflammation, and cash that slowed a baby's aging

They injected healthy volunteers in the forearm with UV-killed E. coli, dead bacteria that can't cause infection but still trigger the redness, heat, and swelling of a real immune response, then gave some of them a drug called GSK2256294 that blocks an enzyme responsible for breaking down a family of fat-derived molecules called epoxy-oxylipins. Block the enzyme, and those molecules stick around longer, acting like brakes on the immune system. In a group of 24 volunteers who got the drug two hours before the trigger, and another group who got it four hours after inflammation had already started, the drug reduced the buildup of a white blood cell called intermediate monocytes, the type that helps healing short-term but drives chronic inflammation when it lingers, and sped up how fast pain eased.

A thousand low-income mothers were split into two groups: 400 got $333 a month, 600 got $20 a month, for the child's first 76 months. That's roughly $4,000 a year extra, about an 18 percent income bump, for the higher group. When the children turned four, researchers swabbed saliva from both kids and moms and measured DunedinPACE, an epigenetic marker of how fast the body is aging. Children in the higher-cash families showed a pace of biological aging 0.17 standard deviations slower than children in the low-cash group. "The fact that we already see differences in four-year-old children in their biological aging is striking," said co-author Kathryn Paige Harden, a behavioral geneticist at the University of Texas at Austin.

They measured nearly 3,000 proteins in blood from 42 participants, average age 67, and ran the results through six separate biological aging clocks, each built differently, each estimating age from a different angle. All six pointed the same direction: people on the drug's 60-milligram daily dose showed blood profiles reading 2.71 to 3.46 years younger after four weeks, while the placebo group's clocks, if anything, ticked up. The researchers were careful not to name one definitive number, since the six clocks disagreed on the size of the effect even as they agreed on its direction.

Four three-toed footprints, each about three feet long, sat connected in the Hell Creek Formation, dated to roughly 66.5 million years ago. Before this, scientists had confirmed only two isolated adult T. rex footprints anywhere in the world, neither connected to another, neither able to show how the animal moved. This trackway let paleontologist Tyler Lyson's team calculate a walking speed: 3.5 to 4.5 miles per hour, about a brisk human pace, across a 13-foot stride. "Bones tell us an enormous amount about these animals, but footprints capture a moment of behavior," Lyson said. "With a trackway, we can actually follow an animal as it moved across the landscape."

So his team compared standard-intensity resistance training against a genuinely low-effort strength program, rather than a waitlist that controls for nothing. Both groups of young women with elevated anxiety saw large drops in depressive symptoms, regardless of whether they were straining under real weight or barely working at all. "We also expanded on our previous research by focusing on anxious young women, as women are generally less involved in muscle-strengthening exercise, and therefore may have greater potential for improvement," O'Sullivan told PsyPost.

The method, called directional freezing, blends soaked legumes into a purée, heats it into a gel, then freezes it from one side only, so ice crystals grow in parallel lines instead of every direction at once. When it thaws, the ice melts away but the fibrous structure stays behind. Red lentils, black lentils, and mung beans produced the strongest, most stable fibers; soybeans and black beans came out softer. "This method is so simple that it can be performed easily by anyone in a household kitchen," said PhD student Andrea Bach, who worked on the research published in npj Science of Food.

He founded Lifespark Technologies and built WALK, a wearable device designed to intervene in that exact frozen moment, alongside PATHFINDER, a platform that tracks movement patterns to flag fall risk for doctors. "As I interacted with patients, clinicians, physiotherapists and researchers, I realised that mobility is not restricted to only movement," Desai said. "It is independence, dignity, confidence and participation in society."

Magnetite powder produced roughly five times more hydrogen per gram than a solid slab of the same mineral, pointing to fractured, porous rock as the best place to look for it in the real world. "Australia could be sitting on a massive, untapped energy reserve, and the potential is enormous," said chemical engineer Alireza Keshavarz. "There is enough hydrogen for Australia to benefit for generations, and potentially enough for us to become a major exporter of clean energy to the rest of the world."
