It’s a phenomenone that happens every single day on Earth, yet it’s one that very few people have every witnessed. In fact, it’s happening somewhere on Earth right now as the last sliver of the Sun dips below the horizon and day slowly fades into night. What is it? It’s the green flash, of course. Wikimedia Commons No, it’s not a comic book character, but a natural phenomenon that occurs just as the Sun sets for the evening.

From the microwave and teflon, to penicillin and viagra, many inventions and discoveries owe themselves to chance or a total accident, and that’s the story of this next breakthrough in the fight against cancer. This story comes to us from Swansea University in the UK where British and Indian scientiests recently discovered that nanoparticles from tea leaves can actually destroy lung cancer cells. Pexels This is all thanks to incredibly small nanoparticles known as quantum dots that are just 1/4000th the thickness of human hair.

Although Christopher Colombus has been credited with discovering North America, others have laid claim to the distinction long before him. One legend says that the Welsh prince Madoc, for example, landed in the America over 300 years before Colombus. Still others claim that the Vikings landed and even established a settlement here. It’s this latter theory that’s gaining a little more credence thanks to an observation from space. The Landing of Vikings in America - H.

Thanks to companies such as Boston Dynamics, we’re developing robots and AI that are capable of remarkable things. We have robots that can walk, run, fight, cook meals, and grow human organs. In addition, today’s aritificial intelligence can teach itself to learn, and kick anyone’s ass in Jeopardy, but in 1939, when the first “Moto Man” robot was unveiled at the Worlds Fair in New York City, the vision for the future was a little bit different.

In the Caribbean waters off the coast of Colombia, treasure hunters have found what many are calling the holy grail of shipwrecks with a treasure of gold, silver, and emeralds that could be worth as much as $17 billion! Wikimedia Commons The search was conducted by the Woods Hole Oceanographic Institution, which used an underwater submarine to investigate the ocean depths. The first sign that they’d found the shipwreck were the cannons strewn all over the bottom of the ocean floor.

NASA just released some images of nearby galaxies photographed by the Hubble space telescope and they are nothing short of breathtaking. NGC 4490 Galaxy - ESA/Hubble The ultraviolet images were all taken as part of the LEGUS project, which is short for Legacy Extra Galactic UV Survey. As part of this project, scientists studied 50 dwarf and spiral galaxies in our local universe (11 to 58 million light years away) by using old and new Hubble observations.

Almost a month to the day after launch NASA’s latest planet hunting satellite sent back its first test image to excited scientists back on earth. The Transiting Exoplanet Survey Satellite (TESS) is designed to look for nearby exoplanets, and so far it’s performing exactly the way it’s supposed to. NASA Launched on Aril 18, the satellite conducted a moon fly-by in order to get a gravity boos that will help launch it toward its final orbit.

Kleptoparasitism is the phenomenon of one animal stealing food or prey from another animal, and it was on full display last week in very dramatic fashion at the San Juan Island National Historical Park in Washington State. Even better, it was all captured on video! PublicDomainPictures.net Here’s the story from ScienceAlert.com: Nature photographer Kevin Ebi of Living Wilderness witnessed this “especially dramatic act of thievery” as he spent a day observing young foxes rest, play, and hunt on the park’s grasslands.

The picture below shows a southerly view of Jupiter. It was snapped by the Juno spacecraft earlier this year in a fly-by when Juno buzzed the orange-spotted planet at a distance of just 10,768 miles. [NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstad/Sean Doran](http://NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstad/Sean Doran) The image clearly shows Jupiter’s Great Red Spot, which is about 1.3 times as wide as Earth. The uniqueness of this photo, however, is due to its view. Prior to Juno’s arrival there in 2016, we were unable to get an image like this.

Michael Jackson’s “Smooth Criminal” video hit the airwaves over 30 years ago in 1987 and it contained a dance move that people are still talking about – and scientists are still studying – to this day. Discover Magazine Right around minute 7:00 in the video below you’ll see MJ lean about 45 degrees forward from a standing position. The average human can only lean 20 degrees or so before falling face first onto the floor, so, naturally, people thought that it was a cinematic special effect.
