| Social secrets of killer whales discovered using drones Posted: 16 Jun 2021 04:15 PM PDT Killer whales have complex social structures including close 'friendships', according to a new study that used drones to film the animals. |
| Exploring the shallow underground world with a burrowing soft robot Posted: 16 Jun 2021 12:42 PM PDT We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers are exploring a new frontier: the ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they've developed a fast, controllable soft robot that can burrow through sand. |
| How a supermassive black hole originates Posted: 16 Jun 2021 11:32 AM PDT How do supermassive black holes in the early universe originate? A team led by a theoretical physicist has come up with an explanation: a massive seed black hole that the collapse of a dark matter halo could produce. |
| Yeast mating -- more than meets the eye Posted: 16 Jun 2021 11:32 AM PDT Researchers have discovered a surprising asymmetry in the mating behavior of unicellular yeast that emerges solely from molecular differences in pheromone signaling. Their results might shed new light on the evolutionary origins of sexual dimorphism in higher eukaryotes. |
| Light in darkness: An experimental look at Paleolithic cave lighting Posted: 16 Jun 2021 11:30 AM PDT A recreation of three common types of Paleolithic lighting systems (torches, grease lamps, and fireplaces) illuminates how Paleolithic cave dwellers might have traveled, lived, and created in the depths of their caves, according to a new study. |
| Electrohydraulic arachno-bot a fascinating lightweight Posted: 16 Jun 2021 09:16 AM PDT Goodbye, bulky components and connectors: A team of scientists has now found a new way to exploit the principles of spiders' joints to create lightweight robots. |
| Bruisable artificial skin could help prosthetics, robots sense injuries Posted: 16 Jun 2021 09:16 AM PDT When someone bumps their elbow against a wall, they not only feel pain but also might experience bruising. Robots and prosthetic limbs don't have these warning signs, which could lead to further injury. Now, researchers have developed an artificial skin that senses force through ionic signals and also changes color from yellow to a bruise-like purple, providing a visual cue that damage has occurred. |
| Mystery solved: Dust cloud led to Betelgeuse's 'Great Dimming' Posted: 16 Jun 2021 08:38 AM PDT When Betelgeuse, a bright orange star in the constellation of Orion, lost more than two-thirds of its brightness in late 2019 and early 2020, astronomers were puzzled. |
| Ten years of ancient genome analysis has taught scientists 'what it means to be human' Posted: 16 Jun 2021 08:38 AM PDT A ball of 4,000-year-old hair frozen in time tangled around a whalebone comb led to the first ever reconstruction of an ancient human genome a decade ago. The hair, which was preserved in arctic permafrost in Greenland, was collected in the 1980s. It wasn't until 2010 that evolutionary biologists were able to use pioneering shotgun DNA sequencing to reconstruct the genetic history of the hair. It sparked a 'decade of discovery.' |
| At underwater site, research team finds 9,000-year-old stone artifacts Posted: 16 Jun 2021 06:41 AM PDT Underwater archaeologists have been studying 9,000-year-old stone tool artifacts discovered in Lake Huron that originated from an obsidian quarry more than 2,000 miles away in central Oregon. The obsidian flakes from the underwater archaeological site represent the oldest and farthest east confirmed specimens of western obsidian ever found in the continental United States. |
| Inkjet printing show promise as new strategy for making e-textiles, study finds Posted: 16 Jun 2021 06:41 AM PDT Researchers demonstrated they could print layers of electrically conductive ink on polyester fabric to make an e-textile that could be used in the design of future wearable devices. |
| ALMA discovers earliest gigantic black hole storm Posted: 16 Jun 2021 06:40 AM PDT Astronomers have discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest-yet-observed example of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the Universe. |
| Space scientists solve a decades-long gamma-ray burst puzzle Posted: 16 Jun 2021 06:40 AM PDT Astrophysicists find the magnetic field in gamma-ray bursts is scrambled after the ejected material crashes into, and shocks, the surrounding medium. |
| Fossil research shows woodlice cousins roamed Ireland 360 million years ago Posted: 16 Jun 2021 06:38 AM PDT The old cousins of the common woodlice were crawling on Irish land as long as 360 million years ago, according to new analysis of a fossil found in Kilkenny, Ireland. |
| Posted: 15 Jun 2021 10:23 AM PDT Hippopotamus aren't the first thing that come to mind when considering epidemiology and disease ecology. And yet these amphibious megafauna offered ecologists a window into the progression of an anthrax outbreak that struck Ruaha National Park, Tanzania, in the dry season of 2017. |
| Let there be light! New tech to revolutionize night vision Posted: 15 Jun 2021 10:21 AM PDT Researchers have developed new technology that allows people to see clearly in the dark, revolutionizing night-vision. |
