Weatherwatch: rainclouds are travelling farther in warmer world

Climate crisis affects not only the amount of rain that falls but where, with implications for land use and water security Have you ever wondered how far a raindrop has travelled before it lands on you? It may have journeyed thousands of kilometres from the ocean, sea or lake it evaporated from – and now research shows raindrops are travelling even farther than they used to. Warmer air can hold more water vapour, and that is changing not only how much rain we receive but also where it falls. Travis Aerenson, of the University of Wyoming, and his colleagues modelled atmospheric moisture movemen

Chemistry textbooks have been getting this wrong for nearly 100 years

A foundational chemistry concept found in textbooks for almost 100 years may have been taught incorrectly. Researchers say the inductive effect in neutral molecules appears to extend only across one chemical bond, rather than gradually weakening over three or four bonds as traditionally taught. The team argues that updating this explanation could make organic chemistry easier to understand and provide a stronger foundation for future research and innovation.

Venus may have swallowed its own moon

Venus may have once had a moon, but new research suggests the planet’s incredibly slow rotation could have doomed it. Computer simulations showed that instead of gradually drifting away like Earth’s moon, a Venusian moon would likely spiral inward until it crashed into the planet, with larger moons falling even faster.

Textbooks may have misdrawn this basic brain structure for 100 years

Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help control how quickly electrical signals travel through the brain.

These blood thinners may have an unexpected benefit for Alzheimer’s patients

Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in cognitive function than those using warfarin or no blood thinners. The effect was modest each year but could add up over time.
