• The surprising new ways bacteria spread without propellers

  Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and creating tiny fluid currents that carry them forward — a newly identified behavior researchers call “swashing.” In another study, a different group of bacteria was shown to control its movement using a microscopic molecular “gearbox” that can reverse direction like a biological snowmobile.

• Scientists discovered a secret deal between a plant and beetles

  A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of those fruits, yet the larvae survive by escaping into the soil. The discovery suggests that fruit drop is not punishment but a compromise that keeps the plant–insect relationship stable.

• Chickpeas could become the first food grown on the Moon

  Scientists have grown chickpeas in simulated moon soil, offering a promising step toward farming on the lunar surface. Researchers mixed moon-like regolith with worm-produced compost and helpful fungi that protect plants from toxic metals. The combination allowed chickpeas to grow and produce a harvest in soil that normally cannot support plant life. Scientists now need to confirm the crops are safe and nutritious for astronauts.

• A “ghost” great white shark just reignited a Mediterranean mystery

  A rare encounter with a juvenile great white shark caught by fishermen in April 2023 has reignited scientific interest in the mysterious population of these apex predators in the Mediterranean Sea. By reviewing records spanning more than 160 years, researchers found that great whites still appear sporadically in Spanish Mediterranean waters, suggesting the population—though elusive and declining—has not vanished. The discovery of a young shark raises an intriguing possibility: these legendary predators may still be reproducing in the region.

• 400 million-year-old fish fossils reveal how life began moving onto land

  Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates that eventually moved onto land. By reanalyzing mysterious fossils from Australia’s famed Gogo Formation and studying a newly reconstructed 410-million-year-old lungfish skull from China, researchers are revealing how these primitive creatures evolved.
