What Would Happen if Rich Countries Gave Away Half Their COVID-19 Vaccines?

New research gives a stark warning to richer nations that have been hoarding their supplies of COVID-19 vaccines: Doing so only has a short-term local benefit, and in the longer term leaves everyone more vulnerable to infection.   Across a five-year model, scientists found that when rich countries gave away 46 percent of their COVID-19 … Read more

Planet Earth Contains Over 9,000 Tree Species Yet to Be Discovered, Scientists Say

An ambitious, first-of-its-kind effort to estimate how many different kinds of trees exist on Earth suggests our planet is teeming with thousands of tree species that still haven’t been discovered.   The huge international research effort – involving the work of over 100 scientists – estimates that there are approximately 73,000 tree species in total … Read more

Hundreds of Strange, Tiny Fossils Found Inside Fish Cranium From 9 Million Years Ago

In a first for paleontology, scientists have found hundreds of tiny, fossilized fecal pellets crammed inside a fish braincase dating to about 9 million years ago. The wee fossil poops, also known as coprolites, were deposited by scavengers – probably worms – that devoured the fish’s decaying head, including its brain.   As they munched the flesh … Read more

US on Track For ‘Staggering’ Flood Damage by 2050, Scientists Predict

Climate change is on track to ramp up the annual cost of US flood damage more than 25 percent by 2050, according to new research Monday that warns disadvantaged communities will likely bear the brunt of the financial burden.   The study published in the journal Nature Climate Change used new flood models to map … Read more

Being a Super-Friendly Dog Has One Potential Drawback, Study Finds

The friendliness of your dog could have serious implications for its social standing with other canines, new research suggests. In a questionnaire designed to measure the personality traits of companion dogs and compare them against their social ranking with other canines in multi-dog families, researchers found that dogs who scored highly for agreeableness and affection … Read more

The Atmosphere of This Extreme Exoplanet Has an Intriguing Similarity to Earth

Astronomers have just peered into the atmosphere of one of the most extreme exoplanets ever discovered. Although it’s absolutely not habitable (at least as we understand it), the exoplanet WASP-189b is the first in which scientists have been able to probe distinct atmospheric layers, each with their own chemical compositions and characteristics.   “In the … Read more

The Lost City of Cahokia Was Mysteriously Abandoned, And We Still Don’t Know Why

For a couple of hundred years, Cahokia was the place to be in what is now the US state of Illinois. The bustling, vibrant city was at one time home to some 15,000 people, but by the end of the 14th century it was deserted – and researchers still aren’t sure why.   A study … Read more

Data From Over 350,000 People Have Really Bad News About ‘Moderate’ Drinking

We all know that drinking too much is bad for us. But what about just a few glasses a week? Red wine has antioxidants, we’ve been told, so a few glasses are apparently ‘good for you‘. Other studies have suggested that low-to-moderate drinkers are less likely to have a heart attack than those who avoid drinking altogether. Wine … Read more

What Actually Is a ‘Bomb Cyclone’? An Atmospheric Scientist Explains

A bomb cyclone is a large, intense midlatitude storm that has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation. It becomes a bomb when its central pressure decreases very quickly – by at least 24 millibars in 24 hours.   Two famed … Read more
