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

Invisible Air Pollution in The Country May Be Just as Toxic as The Smog of The City

It’s easy to see air pollution when it settles as smog over a city. Yet even in rural areas, where the air looks clearer, researchers have found unhealthy particles floating in the atmosphere.   That sweet country air may not be as invigorating as we once thought. Fine particulate matter less than 2.5 micrometers in … 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

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.

Scientists Spent 4 Years Identifying a New Wasp That Only Leaves Its Home For 2 Days

Parasitic gall wasps don’t get out much. For the vast majority of their year-long lives, from eggs to larvae, pupae to adults, these tiny insects are entombed in cocoon-like crypts on the leaves, flowers, and stems of oak trees.   When spring rolls around, there’s no time to waste, not even for food. The wasps … Read more

Wolves Already Had The Genetic Mutation to Turn Into Tiny Dogs 54,000 Years Ago

One of the main genetic mutations responsible for small size in certain dog breeds, such as Pomeranians and Chihuahuas, evolved in dog relatives long before humans began breeding these miniature companions. Researchers discovered that the mutation can even be traced back to wolves that lived more than 50,000 years ago.   Researchers discovered the mutation, which is found in … Read more

Study Confirms Suspicions That Cat Brains Are Smaller Than They Used to Be

As cats have become domesticated over the last 10,000 years or so, their brains have shrunk significantly in size, a new study confirms – a finding that could lead to important new insights into how animals adapt when they start being regularly kept by human beings.   Researchers compared the size of craniums (an indicator … Read more

Wild New Paper Suggests Earth’s Tectonic Activity Has an Unseen Source

Earth is far from a solid mass of rock. The outer layer of our planet – known as the lithosphere – is made up of more than 20 tectonic plates; as these gargantuan slates glide about the face of the planet, we get the movement of continents, and interaction at the boundaries, not least of which is … Read more

Mysterious Effects of Smoking May Surface Even 3 Generations Later, Study Finds

The great-granddaughters of men who smoked cigarettes when they were pre-pubescent boys are more likely to carry excess fat on their bodies as young women several decades later, a rather startling study has found.   The discovery – which scientists claim is one of the “first human demonstrations of transgenerational effects of an environmental exposure … Read more
