A committee made up of high-profile US scientists has a bold plan afoot. It wants to build a billion-dollar particle beam to blast neutrinos 800 miles underground, from Chicago to South Dakota.
At some point in physics class, your teacher probably rubbed a balloon against his hair and explained static electricity. But what your teacher didn't tell you is that scientists are just now realising it is a lot more complicated than thought.
Shark skin is sleek and dragless, the envy of swimsuit designers. Perhaps less famous is what shark skin's oddly rough surface looks like up close: an eerie matrix of microscopic tooth-like scales. Now, scientists are 3D printing artificial shark skin in hopes of unlocking its swimming secrets.
Back in 1934, a team of physicists came up with an idea for how one might create matter from light. Put simply, just slam two photons into each other to get an electron and a positron, a.k.a. matter. And now, some 80 years later, a team of physicists have a plan to carry out the experiment in real life.
Random numbers fuel and protect our digital lives, but they're notoriously difficult to generate properly. Now, scientists have shown that smartphone cameras can be used as quantum random number generators—and it could change the face of mobile security.
