A Strain of Tuberculosis Traveled Across The Pacific Thousands of Years Pre-Contact

Centuries before first contact with Europeans, new research suggests a strain of tuberculosis was already circulating from the South American coasts to the mountains. Deadly European diseases, like tuberculosis (TB), whooping cough, and smallpox, were spread around the world with colonization, but recent evidence indicates this wasn’t the first time TB arrived in South America. … Read more

Giant radiation bubbles created by monster black hole feeding frenzy, new study suggests

Two giant bubbles of gamma rays and X-rays that erupted from the center of the Milky Way may stem from a supermassive black hole‘s feeding frenzy at the heart of the galaxy, a new study finds. Recently, the X-ray telescope eROSITA onboard the Spektr-RG space observatory discovered a pair of gigantic X-ray-emitting bubbles, each about … Read more

This Weirdly Tilted Black Hole Could Upend Our Understanding of How They Form

Black holes could make a strong case for being the most fascinating phenomena in the whole Universe, and scientists are constantly discovering more about the way that they work and behave – including how they’re created in the first place.   Now, a new study of an unusually misaligned one some 10,000 light-years away from … Read more

Weird Link Discovered Between Physical Attractiveness And The Immune System

An extensive new study has found evidence that links physical attractiveness to the functioning of the immune system. While there are still numerous questions left to answer, the researchers suggest their findings show “a relationship between facial attractiveness and immune function is likely to exist.”   Just how reliable that relationship is remains to be seen, however.  … Read more

Fish Have ‘Talked’ For 155 Million Years, And Now You Can Hear Their ‘Voices’

All manner of croaks, chirps, and deep trombone moans permeate Earth’s waters, just like the cacophony of sounds that fill its forest air.

The first life on Earth depended on a deadly poisonous gas, study suggests

At one time, Earth had no life. Then, it did. Whether the process was gradual or rapid, the transformation of chemistry to biochemistry on our planet was one of the most amazing developments to happen in the universe. It’s so rare that to date, we have absolutely no evidence of any form of life anywhere … Read more

Hemp-Derived Compound Offers Benefits of THC With Less Paranoia, Study Suggests

Over the past year, you may have seen something called delta-8 THC or “delta 8” appear in convenience stores and pharmacies alongside CBD gummies, oils, and lotions. Delta-8 THC is a hemp-derived compound that’s closely related to delta-9 THC – what’s commonly called THC and which is the psychoactive component of cannabis that’s responsible for … 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

Gravitational waves play with fast spinning stars, study suggests

Scientists observed changes in the signals coming from rapidly-spinning stars called millisecond pulsars that might point to the existence of subtle space-time ripples vibrating throughout the entire universe. Millisecond pulsars are stellar remnants that spin hundreds of times per second, producing precise radio pulses that can act as a cosmic metronome. Scientists think that ripples … Read more
