Producing power from the wind and sun isn't as simple as just swapping a wind turbine for a coal-fired power plant. Every source of power we use has to work with our electrical grid, an old, imperfect, complex system that wasn't put together with the needs of renewables in mind. For instance, because renewable generation is intermittent generation, using it goes hand-in-hand with ramping production from traditional generation up and down. When you don't have enough wind, you turn up the gas-fire generators. That kind of treatment can put stress on machinery and rack up costs in maintenance and repairs. But new research from the National Renewable Energy Laboratory suggests that, at least in monetary terms, those costs are dwarfed by the cost savings you get from using more wind and solar power and, thus, not having to pay for fuel sources.
NASA released this incredible image of the sky that depicts 22 months of X-ray data captured from the International Space Station using the Neutron star Interior Composition Explorer (NICER). From NASA: “Even with minimal processing, this image reveals the Cygnus Loop, a supernova remnant about 90 light-years across and thought to be 5,000 to 8,000 […]
In the realm of rocket geeks and space nerds, filmmakers MaryLiz Bender and Ryan Chylinski have dream jobs. The pair have the equivalent of “backstage passes” to SpaceX, NASA and ULA rocket launches where they capture and share breathtaking videos that convey the power, risk, and thrill of space exploration. The work of their studio, […]
The 1990s nanotechnology dream of tiny robots swimming through our blood stream to treat disease is moving (verrrry) slowly but surely toward reality. In a new milestone, researchers used an external magnetic field to steer microbots through a live mouse’s body carrying therapeutic stem cells. From IEEE Spectrum: ..Delivering stem cells typically requires an injection […]

Heading abroad? Even if it’s just a short trip, there’s a lot to prepare for. Travel can be incredibly rewarding, but it can tricky to navigate different cultures and lodging arrangements – and even trickier to do it cheaply. Before you go shopping for suitcases, here’s our pick for a good first investment: The Ultimate […]
Fried foods are a weakness for many of us. There’s nothing quite like that extra crisp crackle on chicken, fries or onion rings. And for years, our arteries have been paying for the privilege. Lately, the air fryer has been a godsend for those who love the fried stuff but love their body too. If […]
