A young miner struck something other than gold while digging in the permafrost of Canada’s Klondike. He stumbled across a 35,000-year-old preserved carcass of a woolly mammoth in impeccable condition.
Scientists estimate that our Sun is about 4.57 billion years old. They’re surprisingly confident about that number, too, which opens up an immediate question: how do we know that? The short answer is “a lot of science and math”, but I have a feeling you’re not here for the short answer.
Canada is taking a conscientious step towards reducing plastic pollution. On Monday, the Minister of Environment and Climate Change, Steven Guilbeault, and the Minister of Health, Jean-Yves Duclos, announced their move to prohibit single-use plastics which include: checkout bags, cutlery, food service made from hard-to-recycle plastics, ring carriers, stir sticks, and straws.
How do you see a perfectly black object in the middle of a pitch-dark night? It sounds like the start of an annoying riddle, but it’s really the question faced by astronomers when they want to search for black holes.
Japanese scientists created a self-healing skin for robots. This breakthrough study brings Westworld-like robots one step closer to reality.Is a dystopian future closer than we think?
One of the challenges in establishing a zero-emission green hydrogen network in the US is stabilizing supply and storage. Hydrogen (H2) is a carbon-free fuel and an $8 billion ‘H2 Hubs’ program from the Department of Energy aims to ramp up production. But keeping the industry environmentally neutral is difficult.
Scientists in Egypt have uncovered an odd-looking dinosaur with smaller teeth, stumpy arms, and a squashed face similar to a bulldog.
Bitcoin has been told to clean up its act and drastically cut its environmental impact for the sake of the planet. Annual energy use for the Bitcoin blockchain is estimated to be more than Sweden’s national total. But campaigners say a simple software fix could slash its power use.
Air conditioning (AC) units have become an essential part of modern life, but this simple refrigeration technology has remained relatively unchanged since the 1940s. As climate change effects like rising temperatures and heat waves encourage more AC use, the increase in energy needed to cool us down could easily accelerate climate change.
Only about 40% of an estimated 25,000 near-Earth asteroids with the potential to destroy the planet have been detected. Scientist Dr. Ed Lu, along with his nonprofit B612 are working to create a way to detect the other 60%.
Electronic waste, or e-waste, has reached unsustainable levels. More efforts are needed to reclaim precious metals from discarded laptops and smartphones.
Farmers around the world face serious challenges in growing food more effectively. Climate warming increases the risk of crop damage from insects, fungi, and bacteria. So to manage the threat farms are turning to artificial intelligence (AI), robotics, and computer vision to target pests more effectively.
Coronavirus and the pandemic have made people hyper-aware of reducing their exposure to infection indoors by wearing masks, ventilating rooms, and social distancing. But a new way of using ultraviolet light to kill microbes could rapidly reduce virus particles in public spaces and help prevent future disease outbreaks.
Polar heatwaves in the Arctic and Antarctic have climate scientists concerned about the possibility of rapid climate breakdown. Soaring seasonal temperatures of 40 degrees Celsius above normal in Antarctica and more than 20 Celsius in the Arctic could be a sign of cataclysmic shifts in both regions.
Waste heat is a worldwide energy problem most people have probably never heard about. Every machine and power station, even renewable energy like wind and solar, creates heat that is simply lost in the atmosphere. Thankfully, scientists and engineers are devoted to capturing heat and transforming it into useful electricity.
