Have you ever looked up and wondered, "What does it feel like to soar majestically like an eagle?" This video offers a captivating glimpse. Expert bird handler Lloyd Buck attached a small 360-degree camera and a GPS tracker directly to the back of one of these magnificent predatory birds. The entire setup creates a stunning, first-person virtual reality experience—only this one is real and features a creature with an impressively large wingspan. However, this isn't just for cool footage. The real mission is to capture valuable scientific data: examining how quickly an eagle can gain altitude and precisely how its incredible wings are adapted to achieve such breathtaking, effortless lift.

I like walking. It's really convenient and no fancy equipment is required. You can do it anywhere, anytime. It's also good for my heart and can somehow untangle the chaotic mess that is my brain. It's meditative, allowing my thoughts to flow freely and my anxieties to melt away. Whether it's a short stroll through your neighborhood or a long vigorous hike in the countryside, this TED-Ed video explains why walking is lauded as a cure for everything from boredom to slightly-too-tight jeans.

Right now I'm listening to a cricket. It sounds like it's in my room but I'm quite certain it's not. Do I wish it were in my house instead of outside of it? No, but you do have to admit that would be more interesting.

For some reason I am highly susceptible to earworms. "And baby pulls her hair for a Vicodin. She falls flat on the bed again, mutters something about the end while covering her eyes with both her hands." The title is Guts , from Swedish singer-songwriter Augustine, and I was stuck with this song for nearly six hours before it finally went away. Researchers still haven't figured out what causes earworms, but according to science there are five ways to get rid of them .

You've probably seen—and heard—someone suck a lungful of helium out of a balloon and then speak in a funny voice. But what do you get if you mix wind instruments with helium or sulfur hexafluoride? The folks over at The King of Random performed several experiments to find out what happens when you inhale and play.

Check out this spectacular drone footage showing the migration of 64,000 green sea turtles on Australia's Raine Island. From high above, the pristine water looks like it's speckled with tiny white dots. But a closer look reveals more: each dot is actually a sea turtle swimming toward the shore so it could lay eggs.

A few months ago, the world was introduced to a novel coronavirus—a pathogen that causes COVID-19. The disease has evolved into a full-blown pandemic, and has already claimed the lives of more than two hundred thousand people worldwide. Experts fear that number could get far higher. Pandemics have played a role in shaping the course of human history. Empires have fallen. Generations have been annihilated. In 1518 in France, the weirdest plague to strike mankind occurred: The Dancing Plague. For no apparent reason, hundreds of people began dancing in the streets uncontrollably, and they continued until they dropped dead. "From a distance they might be carnival revellers. But closer inspection reveals a more disquieting scene. Their arms are flailing and their bodies are convulsing spasmodically. Ragged clothes and pinched faces are saturated in sweat. Their eyes are glassy, distant. Blood seeps from swollen feet into leather boots and wooden clogs. These are not revellers bu...

Figuring out how astronauts could live comfortably on Mars is a great challenge. They'll either need to bring materials with them, or make use of the planet's terrain to build settlements. 3D printing seems to be the practical solution, but Malaysian designers Warith Zaki and Amir Amzar think they have a better alternative: locally grown bamboo. The idea seems far-fetched, but why not? Bamboo has been utilized by humans for centuries. It has a high strength-to-weight ratio and can withstand Mars' harsh weather conditions. According to experts, the plant is very likely to thrive on the red planet because CO 2 in its atmosphere is abundant. So, how can we build a bamboo colony on Mars? As Dezeen points out, the concept, named Seed of Life , would require astronauts to land and find underground frozen ice for water. Once ice is found, a self-deploying ETFE structure containing bamboo shoots would be sent. After that, a drill would break into the ice and supply the pla...

A team of MIT engineers have developed a thread-like robot that they hope will make surgeons' lives easier one day. It's less than a millimeter thick and coated in a self-lubricating material. The device is controlled by magnets, and can easily worm its way through hard-to-reach places in the human body. In the future, this robotic thread may be paired with existing endovascular technologies, enabling surgeons to remotely perform delicate procedures. WATCH:

Health officials in the Philippines continue to seek better weapons against dengue fever as death toll from the mosquito-borne disease continues to rise in several regions in the country. Some people use insect repellents, while others use biological alternatives to kill the thirsty little bloodsuckers. Graphene also prevents mosquito bites. A team of researchers at Brown University discovered that graphene-lined clothing not only is an effective physical barrier to those pesky insects, it also blocks chemical signals in sweat that encourage them to bite. "With the graphene, the mosquitoes weren't even landing on the skin patch—they just didn't seem to care," according to Cintia Castillho, a PhD student at Brown and the study's lead author. Since its discovery in 2004, graphene has been dubbed as a wonder material. It is stronger than steel, lighter than paper, conducts heat and electricity, and highly flexible.

Cigarettes are as much an environmental problem as they are a health hazard. Walk along a beach or a bustling street and you step on a lot of cigarette butts. They have poor biodegradability, and for decades they have been thought of as 'unrecyclable'. But an engineer at Australia's RMIT University has found a way to not only divert some of those used filters from ending up in the environment, but also a way to make them into something useful: bricks. Dr. Abbas Mohajerani and his team discovered that fired-clay bricks made with cigarette butts can save energy and help solve a global littering problem. They were found to be lighter with better insulation properties, and their quality is hardly different from that of normal bricks. Mohajerani said: "Incorporating butts into bricks can effectively solve a global litter problem as recycled cigarette butts can be placed in bricks without any fear of leaching or contamination. "They are also cheaper to produc...

A recent study has suggested that magic mushrooms may be a promising treatment option for depression in patients who have not otherwise responded to conventional medicine. Researchers from Imperial College London gave psilocybin, the psychedelic compound in mushrooms, to 12 clinically depressed people. After one week, all of them showed "a marked improvement in their symptoms." From Scientific American : "That is pretty remarkable in the context of currently available treatments," says Robin Carhart-Harris, a neuropsychopharmacologist at Imperial College London and first author of the latest study, which is published in The Lancet Psychiatry. The equivalent remission rate for SSRIs is around 20%.  The study's authors are not suggesting that psilocybin should be a treatment of last resort for depressed patients. "Our conclusion is more sober than that—we are simply saying that this is doable," says Carhart-Harris. "We can give psilocy...

If you're into astronomy, cartography, and art, this map is an absolute delight. It's a scientifically-accurate medieval-style map of Mars, hand-drawn by Seattle-based illustrator Eleanor Lutz. It's called Here There Be Robots , a reference to the myth that cartographers from the Middle Ages would write "here be dragons" in areas that were unexplored. "Recently I've been really into old maps made by medieval explorers," writes Eleanor on her blog . "I thought it would be fun to use their historical design style to illustrate our current adventures into unexplored territory." She completed the map by using data from the Mars Orbiter Laser Altimeter (MOLA), which includes topographic imagery from NASA, and cartography from the USGS Astrogeology Science Center. I really like the map's old time-y appeal. The Red Planet has never looked more otherworldly. [h/t: Nerdist ]

The idea of preserving tattoos after death came into existence long before NAPSA . London's Wellcome Collection has over 300 specimens of preserved human flesh bearing tattoos , collected in the late 19th century. There are many more examples of smaller collections in Paris, Poland, Portugal, Berlin, and Austria. But what fascinates me the most is this lesser-known museum at Tokyo University, the Medical Pathology Museum, which houses pieces of skin collected since 1926 by Dr. Masaichi Fukushi. "Fukushi would perform autopsies on donated cadavers and dissect off just the skin. He created a method of treatment to preserve the skin and kept them stretched in a glass frame, essentially like a leather. Later the ownership of the tattooed skin collection was passed on to Fukushi's son Katsunari. Katsunari added a further 20 tattooed skins himself and it's believed that the Medical Pathology Museum has 105 in its collection, many with full body suits." ...

Researchers at Stockholm's KTH Royal Institute of Technology have just made wood transparent . The new material isn't as crystal clear as glass, but it could be used to build solar panels or houses that let in more natural light.  These badasses developed the transparent 'wood' by removing lignin, the organic compound that makes the wood brown. When combined with acrylic, the lignin-free wood is about 85 percent transparent. It's also stronger and cheaper than glass, and is suitable for mass production. Lars Berglund, who led the research, says they are hoping to "enhance the transparency of the material", and are looking to "scaling up the manufacturing process". [h/t: Gizmodo ]

Future clothes could clean themselves, thanks to a group of Australian scientists. All you'll have to do is hang them outside under the sun and presto, clean laundry.  Researchers from RMIT University in Melbourne have developed what they call "self-cleaning textiles," which contain metallic nanostructures capable of degrading organic matter when exposed to light. Experiments showed that deliberately placed stains vanished within minutes. There's still more work to do before we can say goodbye to laundry day, though. The researchers still have to test the textiles with organic compounds to determine how quickly they can handle common stains like ketchup or baby poo, and they also have to find a way to make the new fabrics affordable enough to end up in your closet.

We all know that hemp has many practical uses, including paper, textiles, construction, health food, and fuel. But in the past few years, scientists have been working on a new way to use the plant. Using perfectly legal hemp fibers, which contain no THC at all, these badasses were able to create cheap, high-performance supercapacitors "better than graphene." "Graphene, an atomically strong material that is 100 times stronger than steel, and conducts electricity at higher efficiency rates than copper, can be applied to transform everyday electronics and machines. The problem is, the carbon monolayer is expensive to produce, which severely limits its adoption in industrial sectors (it cost roughly $2,000 per gram). By comparison, using converted hemp fibers as an alternative for graphene costs less than $500 per ton to manufacture. The process of turning hemp into a superior nanomaterial involves 'cooking' the leftover bark until it turns into carbon nano...
