Did medical equipment capture a near-death experience (NDE) in the brains of two very different coma patients after they were removed from life support? That’s the question at the center of a new study, which may have evidence of two women encountering a bright light or having a similar experience.The first of the patients, aged 24, suffered a heart attack at home and underwent three defibrillations at the hospital – Michigan Medicine, the hospital of the University of Michigan – plus a pa ...read more

The fact that freshwater whales actually exist on our planet deserves far more fanfare — especially considering how their populations are declining.Many species of river dolphins, specifically, live in waterways spanning multiple continents and countries around the globe. Their unique habitats correlate with strange attributes and extraordinary behaviors not found in marine dolphins and other cetaceans.But, as the world's major rivers change under human development, river dolphins seem to be p ...read more

If you feel like something is wrong — say, your stomach or your leg is hurting — you can typically explain to others what’s going on. Maybe you tell a doctor what your symptoms are and what your pain level is, while adding other information to aid the practitioner’s understanding.But cats can’t tell us how they’re feeling.Whatever their ailment, what are some signs that might help us understand our feline friends better and to know if something is wrong? Read on to learn what to look ...read more

Scientists have long thought the humble sea sponge, an animal that feeds by filtering water through itself, forms the oldest group of animals on earth. But a new study claims that the comb jelly phylum is in fact older and carries genetic material from distant, non-animal ancestors.Comb jellies, which look like miniature jellyfishes, use rows of cilia hairs to swim through the ocean and catch prey with tentacles that release a sticky, mucous-like substance. Like other animals, they meet the stan ...read more

A new 3D model of the Titanic, produced using 700,000 images shot by submersibles, reveals the 111-year-old shipwreck to be in a battered condition. Such landmarks as the grand staircase, now lie in complete ruins, while “rusticles” formed by iron-eating bacteria cover the surface.The clock is ticking for the sunken ocean liner, once thought to be “unsinkable,” as experts say it has mere decades before it succumbs completely to the ocean floor.To accelerate research, the new model provid ...read more

Humans who built massive “desert kites” in ancient times first carved to-scale plans of them, creating an 8,000-year-old schematic, a new study says.Scientists found the maps carved into boulders lying on the ground in Jordan and Saudi Arabia, not far from the kites they depicted. Desert kites are ancient, keyhole-shaped structures designed to funnel in animals, which walk in through one end and get stuck in the round enclosure or pit at the other.What Were Desert Kites Used For?The current ...read more

We're hearing a lot about microplastics — those teeny pieces of plastic that have become so ubiquitous in our water, air and soil that they can now be found in human blood. These minuscule pieces of plastic are the product of broken-down waste because plastic does not biodegrade like other materials. Plastics make up a bulk of our packaging, toys, cars, toiletries and building materials; the list goes on and on.What's more, plastics are made up of numerous toxins and chemicals that, when brok ...read more

March 17, 2022, was a rough day for Jorge Vago. A planetary physicist, Vago heads science for part of the European Space Agency’s ExoMars program. His team was mere months from launching Europe’s first Mars rover — a goal they had been working toward for nearly two decades. But on that day, ESA suspended ties with Russia’s space agency over the invasion of Ukraine. The launch had been planned for Kazakhstan’s Baikonur Cosmodrome, which is leased to Russia.“They told us we had to call ...read more

Quantum materials offer many benefits to the future of electronic devices — from batteries to sensors and even our smartphones. Thanks to quantum behaviors like entanglement, these materials exhibit unusual electronic, optical and magnetic properties, making them more energy efficient.“Being superior to conventional materials for certain electronic processes, quantum materials open vast application opportunities,” says Carmine Ortix, an associate professor of physics at the University of S ...read more

Bats often get a bad rap. They’re known mostly as characters in spooky myths or Halloween stories. But these flying mammals are responsible help keep ecosystems in balance and our food economy humming. Bat Species and Their AbilitiesBats comprise one fifth of all living mammal species and are found everywhere on Earth except the ice-covered poles. They first appeared on Earth over 50 million years ago, long before humans. While many people assume bats are related to rodents because of their s ...read more
