SABRE could enable cheaper, more efficient flight, advocates say.

Now that they’ve identified the Higgs boson, scientists at the Large Hadron Collider have set their sights on an even more elusive target.

All around us is dark matter and dark energy—the invisible stuff that binds the galaxy together, but which no one has been able to directly detect. “We know for sure there’s a dark world, and there’s more energy in it than there is in ours,” said LianTao Wang, a University of Chicago professor of physics who studies how to find signals in large particle accelerators like the LHC.

Wang, along with scientists from the University and UChicago-affiliated Fermilab, think they may be able to lead us to its tracks; in a paper published April 3 in Physical Review Letters, they laid out an innovative method for stalking dark matter in the LHC by exploiting a potential particle’s slightly slower speed.

The Orca Helix moves up and down so that it is easy to get on and off when high, easy on the body when low.

Many things have changed in the last hundred years, but one thing that has hardly changed at all is the toilet. And as we have been saying on TreeHugger for what feels like a hundred years, it’s all wrong. Our bodies are designed to squat, yet instead, we sit on 14 inch high seats, which actually makes it hard to poop. As we get older, or fatter, people have trouble even getting on a 14 inch seat and buy “comfort height” toilets, which make it even harder to poop. It is exactly the wrong thing to do, causing constipation, haemorrhoids and worse.

One of Huntsville’s historic Apollo engine test stands is coming back to life under an agreement between NASA and Jeff Bezos’ Blue Origin space company.

NASA announced Wednesday it has signed an agreement to let Blue Origin use Marshall Test Stand 4670 to test its BE-3U and BE-4 rocket engines. The BE-4 has been selected to power United Launch Alliance’s new Vulcan rocket and Blue’s New Glenn rocket.

Both rockets are being built to power new boosters for America’s three key space markets: NASA, commercial companies like ULA and national security customers such as the Air Force.

Two new studies confirm that weight control is often the result of genetics, not willpower.

Scientists have developed a first-of-its-kind device that generates electricity from nothing other than the natural phenomenon of snowfall.

Based upon the principles of the triboelectric effect, in which electrical charge is generated after two materials come into contact with one another, the researchers’ new technology exploits the fact that snow particles carry a positive electrical charge.

Because of that, snowflakes give up electrons, provided they get a chance to interact with the right, negatively charged substance.
