Life on the ice: Extraterrestrial life on ice worlds could look like Hawaiian underwater creatures
Those looking for signs of life outside our planet should take a look first at what’s living deep beneath the ocean’s surface, according to astrobiologists. In a talk presented at the Astrobiology Science Conference, post-doctoral investigator Amy Smith said the Lo’ihi seamount, located just off the southeastern coast of Hawaii’s Big Island, can mimic the […]

Researchers develop a procedure that can extract diesel fuel from water and soil
With the ever-increasing number of vehicles on the road, concern surrounding the risk of contaminating the environment with diesel fuel — and other petroleum-based products — is also rising. Diesel fuel is an extremely noxious pollutant: when spilled on water, it stays mainly on the surface, which ends up decreasing the water’s oxygen concentration, resulting […]

Astronomers discover and decode strange signals from a 3-body star system
Did you know that there has been an object in the Milky Way 500 light-years away that “blinks” at us daily? Now, astronomers have figured out the reason for this unusual signal. Called NGTS-7, this celestial object is part of binary system NGTS-7ABM, and appears to most telescopes as a single star. In 2019 however, […]

Seashell-inspired shatterproof glass: Researchers engineer strong composite glass based on mother of pearl that can resist impact
Despite their delicate appearance, seashells are surprisingly durable. This unexpected durability comes from the tough, impact-resistant substance known as nacre, also known as mother of pearl. Nacre is an organic-inorganic composite material that also gives seashells their signature iridescence. It is made up of microscopic calcium carbonate tablets mortared together by proteins. Arranged like bricks, […]

Updating fluid-powered machines: Scientists design bizarre-looking lionfish powered by a blood-like compound
You’ve heard of robots that can run, lift, jump and crawl. Now, prepare to see one that can bleed. In a paper published in the scientific journal Nature, a joint team of researchers from Cornell University and the University of Pennsylvania detailed how they built a soft robotic lionfish, complete with a multi-functional circulatory system. […]

Engineers develop robot gripping arm that “tastes” using bacteria
Much like how octopuses and squids use their tentacles, a new biohybrid robot developed by a joint team of researchers uses its fingers to “taste” the world around it. Created by a team of researchers from the University of California, Davis (UC Davis), and Carnegie Mellon University (CMU), the biohybrid robot uses a bioengineered strain […]

No pain, no gain: Research suggests naked mole rat gene holds the secret to pain tolerance
Perhaps due to its lackluster appearance – wrinkly, with a body reminiscent of a pale, leathery sausage – the naked mole rat is the last animal you’d think to possess abilities akin to superpowers. But they do. Known for its long lifespan, relative immunity to most cancers, ability to survive more than 18 minutes without […]

Scientists use computer simulations to understand the possibility of hyperspace travel via black holes
One of the most common tropes in science fiction involves the use of black holes as portals to other dimensions or points in time. A recent study suggests that such a scenario may be closer to reality than it is to fantasy. While scientists have predominantly believed that using black holes – a region of space-time exhibiting […]

A nose for numbers: Elephants can “count” food using their sense of smell, study says
When it comes to function, elephant trunks are the Swiss army knives of the natural world. Bristling with over 150,000 individual muscle units, an elephant’s trunk is used for a wide variety of activities: sucking up water for drinking, blowing out dust for baths, picking up objects, sending out warnings and even using them to greet […]

A dead supercontinent is partly responsible for the ocean sinking into the Earth’s mantle, explain researchers
Every day, hundreds of millions of gallons of water drain from the oceans into the Earth’s mantle, and geologists think that a dead supercontinent may be to blame. Dubbed the “deep water cycle” or the “geologic water cycle,” this phenomenon occurs when water gets soaked up by minerals within the earth’s mantle through a process called subduction. As the […]
