A 70-million-year old dinosaur species possessed massive, scissor-like chompers that it probably used to gnawthrough the tough, fibrous leaves of ancient palm trees. The discovery might help explain how multiple species of vegetarian dinos could co-exist in prehistoric Europe: this new dinosaur likely ate the parts of plants that no one else wanted.
The toothy dinosaur, described this week in the journal Scientific Reports, was discovered in the south of France among a jumble of bones from other dinosaurs and reptiles. Called Matheronodon provincialis, all that remains of this new species is an 8-inch long chunk of its right upper jaw, and a few loose teeth that may have come from other individuals. The researchers estimate based on…
Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib. Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism, allowing the tooth to repair cavities.
Tideglusib works by stimulating stem cells in the pulp of teeth, the source of new dentine. Dentine is the mineralized substance beneath tooth enamel that gets eaten away by tooth decay.
Teeth can naturally regenerate dentine without assistance, but only under certain circumstances. The pulp must be exposed through infection (such as decay) or trauma to prompt the manufacture of dentine. But even then, the tooth can only regrow a very thin layer naturally—not enough to repair cavities caused by decay, which are generally deep. Tideglusib changes this outcome because it turns off the GSK-3 enzyme, which stops dentine from forming.
In the research, the team inserted small, biodegradable sponges made of collagen soaked in Tideglusib into cavities. The sponges triggered dentine growth and within six weeks, the damage was repaired. The collagen structure of the sponges melted away, leaving only the intact tooth.
Thus far, the procedure has only been used in mouse teeth. Yet as King’s College London Dental Institute Professor and lead author Paul Sharpe told The Telegraph, “Using a drug that has already been tested in clinical trials for Alzheimer’s disease provides a real opportunity to get this dental treatment quickly into clinics.”
He added, “The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine.”
Bluetooth Special Interest Group (SIG) has added support for mesh networks, aimed at creating large-scale device networks for automation, sensor networks, and Internet of Things (IoT) solutions. It is another update focused on making Bluetooth a more viable option for IoT and many-to-many device communications. Previous updates have included extended range, increased speed, and better power management.

Say hello to Amabrush, the world’s first automatic toothbrush, and goodbye to brushing your teeth for minutes at a time twice a day. Amabrush resembles a mouthguard with soft silicone bristles in it, and it is magnetically attached to a round handle. Put the mouthpiece in, and don’t worry about the toothpaste, it’ll do that for you. It will then go to work, brushing your teeth in the way that your dentist tells you to, in every location in your mouth, all at the same time.
Using this device, brushing all of your teeth to perfection only takes about 10 seconds from start to finish, so it’s no surprise that the Amabrush is doing really well on Kickstarter. As this article is being written, they have 25 days to go and have already raised $ 935,891, surpassing their $ 56,972 goal.
The Amabrush is just one more example of automation doing what it does best: taking over mind-numbingly dull daily tasks, freeing up humans to think about and do more compelling things. Whether it’s a significant step in automation, like self-driving cars, or just a piece of the puzzle, it’s all progress in the same direction. By extension, automation can free us from repetitive, dull jobs and free us up for more challenging careers, hobbies, passions, etc. All we have to do is be willing and ready for this change to happen.
