A bacterium that feeds on toxic plastic has been discovered by scientists. The bug not only breaks the plastic down but uses it as food to power the process. The bacterium, which was found at a waste site where plastic had been dumped, is the first that is known to attack polyurethane. Millions of tonnes of the plastic is produced every year to use in items such as sports shoes, nappies, kitchen sponges and as foam insulation, but it is mostly sent to landfill because it it too tough to recycle.

Your pearly whites are capable of far more than chewing, a new study reveals. Teeth can disclose intimate details about your life. Researchers discovered that physiologically impactful events in our lives – periods that may be stressful, such as birth, disease, menopause; incarceration – all leave a permanent record on our gnashers.

In 2009, Hobby Lobby president Steve Green began acquiring a collection of 16 Dead Sea Scrolls for his Museum of the Bible, a sprawling institution in Washington, D.C. that seeks to provide “an immersive and personalized experience with the Bible, and its ongoing impact on the world around us.”

When Daniel Field first saw it, his shouts echoed down the hall. “That moment was probably the most shocking moment of my life, certainly the most shocking moment of my scientific career,” he says. The chunk of rock didn’t look like much. It was small and uninspiring, about the size of a deck of cards, says Dr. Field, a paleontologist at the University of Cambridge. But fragments of birdlike bone poked out of it, and it was from the last days of the dinosaurs, so it bore further scrutiny.

Under layers of dirt, pinpricked with animal burrows and shrubs, archeologists found a circle of mammoth bones — evidence of a dwelling built between 25,063 to 24,490 years ago.

Astronomers from Nanjing University in China have detected gamma ray emission from two star-forming galaxies designated M33 and Arp 299. The finding, which is detailed in a paper published March 17 on arXiv.org, could be helpful in improving knowledge about the origin of very high-energy emission in galaxies.

The complete skull of a previously unknown species of bird-like dinosaur has been discovered trapped in a chunk of 99-million-year-old amber. Smaller than the size of the tiniest hummingbird alive today, its head was the size of a thumbnail, its jaw packed with serrated teeth and its eyes bulging and lizard-like. Despite its teeny-tiny stature, the creature was likely a predator.

A large rocky exoplanet twice the size of the Earth has been discovered. it has habitable zone and could sustain alien life.

Scientists have discovered something they didn't think existed: an animal that can't breathe oxygen, and obviously doesn't need to. That animal is a parasite called Henneguya salminocola, distantly related to jellyfish. It lives in the muscles of salmon and trout, causing unsightly little white nodules known as "tapioca disease."

Scientists have discovered the first fast radio burst that beats at a steady rhythm, and the mysterious repeating signal is coming from the outskirts of another galaxy.

Scientists for the first time have developed a single molecule that can absorb sunlight efficiently and also act as a catalyst to transform solar energy into hydrogen, a clean alternative to fuel for things like gas-powered vehicles.

Earlier this month astronomers found strange repeating signals emanating from deep space. Now a top astronomer has said there’s a possibility they were produced by an alien civilisation. The transmissions are called fast radio bursts and are similar to other signals which have been spotted before. But the recent burst is believed to be the first with a discernible pattern.

Researchers using ESO's Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.

A Canadian team of scientists has successfully isolated a strain of the coronavirus and grown samples in a lab to help study the pathogen responsible for the deadly global pandemic. Researchers from Sunnybrook Research Institute, McMaster University and the University of Toronto, all in Canada, isolated the virus from two specimens and then cultivated it in a secure containment facility.

Just as astronomers thought they were making sense of fast radio bursts (FRBs) — the mysterious repeating signals originating deep in space — the universe threw us a curveball.

Material falling into a black hole casts X-rays out into space—and now astronomers have used the echoes of this radiation to map the dynamic behavior and surroundings of a black hole itself. Most black holes are too small on the sky for us to determine their immediate environment, but we can still explore these mysterious objects by watching how matter behaves as it nears, and falls into, them.

British scientists may have discovered a cure for cancer — by accident. As The Telegraph reports, “Researchers at Cardiff University were analyzing blood from a bank in Wales, looking for immune cells that could fight bacteria, when they found an entirely new type of T-cell. That new immune cell carries a never-before-seen receptor which acts like a grappling hook, latching on to most human cancers, while ignoring healthy cells.”

During the Stone Age in what is now western Cameroon, four children who perished before their prime were buried in a natural rock shelter. Now, thousands of years later, an analysis of the ancient DNA found in their bones has revealed secrets about the people who lived there many millennia ago, according to a new

Viruses are some of the most mysterious organisms on Earth. They’re among the world’s tiniest lifeforms, and because none can survive and reproduce without a host, some scientists have questioned whether they should even be considered living things. Now, scientists have discovered one that has no recognizable genes, making it among the strangest of all known viruses.

A new species of tyrannosaur — the oldest ever found in Canada — has been discovered in Alberta. Thanatotheristes degrootorum was as long as two cars lined up bumper to bumper and would have towered over an adult human. It stood about 2.4 metres tall at the hips, said Jared Voris, a University of Calgary PhD candidate who led the research identifying it as a new species.
