If you’ve wondered how dolphins eat, you aren’t alone. This month, a new study published in PLOS aims to figure out just that. And to do that, the study’s lead author Sam Ridgway strapped cameras onto six dolphins trained by the Navy and let them loose. The footage captured by Ridgway and his team clearly showcases how the dolphins hunt and even the way that they eat their prey. Dolphins are intelligent creatures, even going so far as to teach other dolphins tricks. But, when it came to feeding and hunting, they…

A new video captured in the mesopelagic zone finally shows scientists how giant squids stalk and attack their prey in the deep ocean. The video is the first of its kind. Researchers used longer-wavelength red lighting to light the way for an underwater vehicle. This allowed them to capture the giant squids attacking prey without annoying them. New video captures giant squids attacking prey in natural environment for the first time https://www.youtube.com/watch?v=lGfh95dERyE Nathan Robinson, with the…

Astronomers say that a bunch of asteroids could hide in the Sun’s glare. These near-Earth asteroids would most likely be objects we’ve never detected, as most telescope systems look outward from our Solar System. Recent surveys have revealed never-before-seen asteroids hiding near Venus and other planets in our Solar System. Astronomers found never-before-seen asteroids hiding in the Sun’s glare Image source: lukszczepanski/AdobeFinding never-before-seen asteroids hiding out near Earth isn’t surprising.…

What’s the news?: Deep learning is behind machine learning’s most high-profile successes. But this incredible performance comes at a cost: training deep-learning models requires huge amounts of energy. Now, new research shows how scientists who use cloud platforms to train algorithms can dramatically reduce the energy they use, and therefore the emissions they create.How can they do it?: Simple changes to cloud settings are the key. Researchers created a tool that measures the electricity usage of any machine-learning…

Physicists say they've found evidence in data from Europe's Large Hadron Collider for three never-before-seen combinations of quarks, just as the world's largest particle-smasher is beginning a new round of high-energy experiments.  The three exotic types of particles – which include two four-quark combinations, known as tetraquarks, plus a five-quark unit called a pentaquark – are totally consistent with the Standard Model, the decades-old theory that describes the structure of atoms.In contrast, scientists hope that…

Researchers have discovered never-before-seen types of crystal hidden in tiny grains of perfectly preserved meteorite dust. The dust was left behind by a massive space rock that exploded over Chelyabinsk, Russia, nine years ago.  On 15 Feb 2013, an asteroid measuring 59 feet (18 meters) across and weighing 12,125 tons (11,000 metric tons) entered Earth's atmosphere at around 41,600 mph (66,950 km/h).Fortunately, the meteor exploded around 14.5 miles (23.3 kilometers) above the city of Chelyabinsk in southern Russia,…

Scientists have discovered a new, mysterious particle. Of course, making new discoveries is exciting. But, perhaps the most exciting thing about this particle is that it could be a candidate for dark matter. Incredibly, the never-before-seen particle was discovered using an experiment small enough to fit on a kitchen counter.

Scientists have discovered a clever mimicry trick used by some bats: they'll buzz like hornets when they think they're under threat from predators, giving the sonic impression they're more dangerous than they actually are.  It's the first time behavior like this has been recorded in mammals, but it happens elsewhere in the animal kingdom – such as when the wings of moths are patterned to appear like the insect is actually a different, much more dangerous species. The technical term for it is Batesian mimicry.The team…

An expedition to a deep-sea ridge, just north of the Hawaiian Islands, has revealed an ancient dried-out lake bed paved with what looks like a yellow brick road.The eerie scene was chanced upon by the exploration vessel Nautilus, which is currently surveying the Liliʻuokalani ridge within Papahānaumokuākea Marine National Monument (PMNM).  PMNM is one of the largest marine conservation areas in the world, larger than all the national parks in the United States combined, and we've only explored about 3 percent of its…
