➀ Researchers have identified a protein within the genetic code of fruit flies that can extend their lifespan by up to 30% when altered. ➁ The protein, F-actin, accumulates in the brain and slows down cellular cleaning, leading to waste build-up. ➂ The study suggests that manipulating F-actin could potentially extend human life.

➀ Researchers at Northwestern University have captured the nanoscale formation of a water molecule for the first time; ➁ Using palladium as a catalyst, they observed hydrogen and oxygen atoms merging to form H2O; ➂ The team achieved this by using a special ultra-thin glassy membrane and a high-vacuum electron microscope.

➀ An international team of researchers has found that 70% of all known meteorite collisions with Earth have come from just three meteorite families; ➁ These families, Karin, Koronos, and Massalia, were formed around 40 million years ago; ➂ The study reveals the origins of 90% of known meteorites.
