The US can pretty easily turn its back on Russian oil and gas and has and has not been able to pull the trigger on uranium because we rely on Russia for a significant chunk of our uranium.It supplies about 16% of the US’s uranium supply and upwards of that when it comes to the global uranium supply. Nuclear power is a highly contested energy source, but it still makes up about half of our carbon pollution free electricity in the U.S. Right now, the Biden administration is investing a lot of money and resources into its expansion, from extending the life span of old plants to building new ones.#Uranium #RussiaUkraineWar #NuclearEnergy #NuclearFuel #NuclearPower #Seeker #TheVergeRead more: The US Can’t Seem to Quit Russian Uranium theverge.com/2022/3/31/23003494/war-ukraine-nuclear-energy-uranium-russia-supply-chainThe US’s exclusion of uranium from energy sanctions “was very frustrating because we understand that this is part of the Russian war machine,” says Kostiantyn Krynytskyi, head of the energy department at Ukrainian environmental organization Ekodia.

And these images are just a glimpse into what JWST can really do. It took two and a half decades to build and launch JWST, the largest and most advanced space telescope ever built. Unlike its predecessor Hubble, Webb can observe way farther into the infrared part of the spectrum, giving it an even better look at the first galaxies formed after the Big Bang. The telescope will help us understand how the cosmos began, and whether we’re alone out there. First, we have the deepest and sharpest infrared image ever taken of our universe. It’s a region full of thousands of galaxies. And because the light from these distant objects takes so long to reach us, we’re seeing them as they were when the universe was less than a billion years old. Then there’s the Carina Nebula, a stellar nursery. This image provides a glimpse into how stars form. It was imaged by Hubble…but this new view reveals new stars…and some new mysteries.On the other end of the stellar life cycle, there’s the Southern Ring. It’s a region of cosmic dust and gas that surrounds a dying star. The telescope captured two views in different chunks of the infrared spectrum, revealing a clearer view of the binary star at the nebula’s center.Then there’s Stephan’s Quintet, a compact group of five galaxies. Highlights here are two galaxies in the process of merging, and a region of extremely bright gas being pulled into a black hole.And finally, this is the telescope’s first spectrum of an exoplanet’s atmosphere. This graph reveals the atmospheric composition of a large, hot planet far from our own solar system. Data like this can reveal whether a world may sustain life as we know it....in this case, we can see the tell-tale signs of water vapor.

Science Can’t Figure Out Why Some Liquids Flow Seeker 2022-05-30 | Scientists are still trying to understand why not all liquids flow in the same way. One recent study dove into the complexities of pusher fluids used for extracting oil and solved a decades-old mystery. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylistFluids are a necessary part of day to day life. After all, without water you couldn’t live, and without chocolate syrup, well, what would be the point? But have you ever noticed that not all liquids behave the same? In fact, some of them do some totally bewildering stuff under the right circumstances, and even after decades of research scientists are no closer to understanding why. One question about strange fluids may have finally been answered thanks to some glass beads and laser beams. All liquids that we encounter in the real world can be boiled down to one of two kinds. They’re either Newtonian, or non-Newtonian. Newtonian fluids are pretty easy to grasp. Well, not literally in some cases—a Newtonian fluid like water would squirt right out of your hand. A Newtonian fluid obeys Newton's Law of Viscosity which means its viscosity is constant. It doesn’t change when a force is applied to it. Non-Newtonian fluids, on the other, less sticky hand, do change their viscosity…which can lead to some pretty zany shenanigans.Still there are many more weird non-Newtonian behaviors scientists don’t have answers for. They may have just solved one riddle that’s stood for over 50 years. #Liquid #Chemistry #LawsOfMotion #Gravity #IsaacNewton #SeekerRead More: An Injection of Chaos Solves Decades-Old Fluid Mystery quantamagazine.org/an-injection-of-chaos-solves-decades-old-fluid-mystery-20220104 One such long-standing puzzle, first articulated nearly 55 years ago, arises when certain liquids stream through cracks and holes in a porous landscape such as spongy soil.Your Next Surgeon Could Be a Slime Robotcnet.com/science/your-next-surgeon-could-be-a-magnetic-slime-robot Created by a team of researchers at the Chinese University of Hong Kong, the Slime Robot is a non-Newtonian fluid, meaning it can behave both as a solid and a liquid.

The Sahara Desert Used to Look Like This…And May Again Seeker 2022-05-18 | Thousands of years ago, the Sahel region of Africa was a green, lush, tropical paradise. The Great Green Wall initiative is on a mission to restore that greenery in that region across the entire continent. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylistThe Great Green Wall is an epic project that aims to grow an 8,000 kilometer belt of vegetation across the entire width of the African continent. If completed, it would be three times larger than the Great Barrier Reef, and be the largest living “structure” on the planet. But can this massive geo-engineering project transform the landscape into the fertile, tropical place it once was? So here’s the thing: this part of Africa is heating up. Particularly in the Sahel, which sits between the southern edge of the world’s largest hot desert, the Sahara, and humid savannas to the south. Vegetation is scarce in this semi-arid belt of land, and the U.N. has identified it as a hotspot for climate change. Temperatures in the Sahel region are increasing 1.5 times faster than the rest of the world, and the Sahara desert is now 10% larger than it was in 1920. Periodic drought, deforestation, and unsustainable agricultural practices have reduced the productivity of the Sahel, causing desertification. This has led to massive food insecurity and displacement of people in the region. And with temperatures expected to be 3-5°C warmer by 2050, these problems are projected to get worse.But not all is lost! Remember when we said the Sahara used to be green? Well, that was about 11,500 years ago. Back then there was grass, lakes, and animals like hippos and antelopes! Dubbed the African Humid Period, also known as the “Green Sahara,” this era was the result of intense West African monsoons, which were stronger and brought more summer rainfall than today. #SaharaDesert #Sahara #Africa #Algeria #ClimateChange #Environment #Desertification #SeekerRead More: Africa’s ‘Great Green Wall’ shifts focus to hold off desert politico.com/news/2021/11/13/africa-great-green-wall-521292 The project called the Great Green Wall began in 2007 with a vision for the trees to extend like a belt across the vast Sahel region, from Senegal in the west to Djibouti in the east, by 2030. But as temperatures rose and rainfall diminished, millions of the planted trees died. Could the Sahara ever be green again? livescience.com/will-sahara-desert-turn-green.html Sometime between 11,000 and 5,000 years ago, after the last ice age ended, the Sahara Desert transformed. Green vegetation grew atop the sandy dunes and increased rainfall turned arid caverns into lakes. About 3.5 million square miles (9 million square kilometers) of Northern Africa turned green, drawing in animals such as hippos, antelopes, elephants and aurochs (wild ancestors of domesticated cattle), who feasted on its thriving grasses and shrubs. Africa’s ‘Great Green Wall’ could have far-reaching climate effects sciencenews.org/article/africa-great-green-wall-trees-sahel-climate-change To investigate those possible impacts, Pausata created high-resolution computer simulations of future global warming, both with and without a simulated wall of plants along the Sahel. Against the backdrop of global warming, the Great Green Wall would decrease average summertime temperatures in most of the Sahel by as much as 1.5 degrees Celsius.____________________Elements is more than just a science show.

How does one man plan to clean it up?Special thanks to Jackson Wild » Subscribe to Seeker! http://bit.ly/subscribeseeker» Catch up on Seeker Indie! bit.ly/3cpNPcfIn Indonesia, the ocean plays a critical role in people’s livelihood; from their food to their careers. But that important life source is under threat from overwhelming amounts of plastic. Unfortunately, this pollution is fueled from one of Indonesia’s most popular tourist destinations, Bali. This, combined with plastic from the rest of the world, washes up on beaches, gets hooked by local fishermen, and damages marine ecosystems. This film follows Wayan, a 90-year-old Balinese fisherman using all his resources and knowledge to tackle this growing problem, one net of trash at a time. This is Voice Above Water, a production from Turning Tides Films. #PlasticPollution #Oceans #PlasticWaste #Plastic #Pollution #Environment #Seeker____________________Seeker empowers the curious to understand the science shaping our world.
