Losing a tooth has always meant a lifetime sentence of awkward implants, clacky dentures, or pretending you’ve “always had that gap.” But scientists in Japan are now trialling a drug that could make all of that redundant, by letting you grow a brand new set. Yes, tooth fairy, your job is officially on notice. The breakthrough comes from researchers at Kitano Hospital in Osaka, who discovered that humans carry dormant “third-set” tooth buds hidden under the gums. Normally, a protein called USAG-1 tells them to stay asleep forever. The Japanese team simply worked out how to shut that protein up

If someone told you the U.S. military once patented a way to beam voices directly into your head, you’d probably laugh it off as a late-night conspiracy rant. But the unsettling truth is they did. In 2002 a patent was filed for what’s known as the microwave auditory effect. By 2003 it was granted as US Patent 6,587,729 B2. The invention describes using directed microwave energy to transmit sounds, even speech, straight into a person’s skull. No headphones, no speakers, no visible device at all. How it works Microwaves, when pulsed in very specific ways, can cause the human ear

They exiled him from America. But Einstein once called him “my successor.” David Bohm was not your average physicist. He had the kind of ideas that get you quietly uninvited from conferences, and sometimes entire countries. His crime? Suggesting that reality might not be the chaotic mess most physicists assumed it to be. Instead, he argued, everything is connected. Every particle, every thought, every moment belongs to a deeper order he called the Implicate Order. Think of reality as water. Drop two pebbles into a pond and you see ripples spreading, crossing, interfering. It looks random, but it is not.

String theory is the Beyoncé of physics. Hugely ambitious, adored by some, divisive to others, and always in danger of being upstaged. For decades, it has promised to unify all the fundamental forces into one elegant framework, explaining reality from quarks to black holes. But now a group of physicists at the University of Pennsylvania and Arizona State University has spotted a crack in the choreography. They have identified a theoretical family of particles—known as a 5-plet—that string theory says should not exist. Among the suspects is the Majorana fermion, a particle so peculiar it is its own antiparticle. Imagine
