National fusion project passes new milestone

Today, the National Ignition Facility passed a new milestone, heating a hydrogen fuel until it emitted more energy than it absorbed, fueled by the atomic energy released in fusion. The results bring the lab one step closer to turning nuclear fusion into a viable power source — although, as scientists were quick to note, there's still a long way to go.
The process works by shining 192 beams from a powerful laser into a small pellet of hydrogen fuel, hoping to heat a small area to the extreme temperatures required for fusion. While the lab has succeeded in getting the fuel to export energy, the process overall is still a net energy loser, thanks to inefficiencies in the laser system. Still, scientists believe the results will provide an important boost for the project, and potentially spur further research into nuclear fusion as an energy source.

Einstein’s Lost Theory Describes a Universe Without a Big Bang

Einstein with Edwin Hubble, in 1931, at the Mount Wilson Observatory in California, looking through the lens of the 100-inch telescope through which Hubble discovered the expansion of the universe in 1929. Courtesy of the Archives, Calif Inst of Technology. In 1917, a year after Albert Einstein’s general theory of relativity was published—but still two years before he would become the international celebrity we know—Einstein chose to tackle the entire universe . For anyone else, this might seem an exceedingly ambitious task—but this was Einstein. Einstein began by applying his field equations of gravitation to what he considered to be the entire universe. The field equations were the mathematical essence of his general theory of relativity, which extended Newton’s theory of gravity to realms where speeds approach that of light and masses are very large. But his math was better than he wanted to believe—...

There’s a Previously Undiscovered Organ in Your Body, And It Could Explain How Cancer Spreads

Ever heard of the interstitium? No? That’s OK, you’re not alone — scientists hadn’t either. Until recently. And, hey, guess what — you’ve got one! The interstitium is your newest organ. Scientists identified it for the first time because they are better able to observe living tissues at a microscopic scale, according to a recent study published in Scientific Reports , Scientists had long believed that connective tissue surrounding our organs was a thick, compact layer. That’s what they saw when they looked at it in the lab, outside the body, at least. But in a routine endoscopy (exploration of the gastrointestinal tract), a micro camera revealed something unexpected: When observed in a living body, the connective tissue turned out to be “an open, fluid-filled space supported by a lattice made of thick collagen bundles,” pathologist and study author Neil Theise told Research Gate . This network of channels is present throughout ...
