• Australia’s red soil may be hiding a massive clean energy source

  Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a major new source of low-emission energy for Australia and potentially the world.

• Dogs may hold surprising clues to human longevity

  Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ways to those seen in people. These metabolic “fingerprints” could offer clues about the biological processes that drive aging, including metabolism, inflammation, and cellular stress.

• Scientists turn one of the hardest plastics to recycle into high-performance engine lubricant

  Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains of plastic waste a valuable second life while making lubricant production more sustainable.

• Scientists tested 212 plant-based meat alternatives. Every one contained fungal toxins

  Every one of 212 plant-based meat alternatives and drinks tested in the UK contained at least one naturally occurring fungal toxin, though concentrations remained below recommended EU guideline levels. Researchers say the bigger question is whether regularly eating large amounts of these foods could lead to potentially concerning cumulative exposure over time.

• Scientists tracked 4,500 animals and found a surprising human effect

  Scientists tracking thousands of animals found that our physical presence can reshape where wildlife moves and lives, sometimes as strongly as roads, cities, and other human development. Because different species reacted in very different ways, conservation efforts may need to become much more targeted.
