Scientists find bacteria resistant to last-ditch drug treatments

If there wasn’t already a reason to develop a solution to drug-resistant “superbugs, ” there is now. Scientists have found bacteria on an American pig farm that resists carbapenems, a variety of antibiotics used only against germs that resist normal antibiotics. There was a similar incident with cattle earlier in 2016, but that bacteria couldn’t transmit its resistance to anything but its offspring — this strain could jump between bacteria without much trouble. Thankfully, the scientists didn’t find evidence of the bacteria reaching the pigs or their food supply. And while the bacteria would pose a threat to people who are already sick, it’s not normally dangerous to humans. That’s not exactly reassuring in the long term, though, and the team tells Popular Science that it wants to find methods of preventing this sort of contamination in the future. The group is also worried about the resistant bacteria’s origins. It’s unlikely that the resistance developed at the farm given the lack of antibiotics, so there’s a good chance that it came from something outside. Plenty of research is underway to develop both more sophisticated antibiotics and treatments that avoid antibiotics altogether. However, this discovery reinforces the need for short-term steps to prevent particularly stubborn bacteria from spreading, such as better procedures and preventative technology . Ideally, the medical community would buy enough time to have a true answer to superbugs before the best available options prove ineffective.

Regenerative tooth fillings could put an end to root canals

You really don’t want a root canal, and not just because it’s potentially painful. Emptying the tooth of the infected tissue at its heart potentially weakens it, since you can’t grow that organic material back or put toxic fillings in its place. Researchers may have a solution, though. They’ve crafted fillings that get the tooth’s own stem cells to regenerate and repair tissue. This doesn’t mean that your pearly whites would return to normal, but the substance could heal the tooth enough to spare you a root canal or prevent fillings from going south. You’re not going to have this option for a while, but it’s designed to be practical. You can cure the filling with light, so your dentist wouldn’t have to resort to exotic techniques to rescue your teeth. And importantly, it might be less expensive overall — you might not need a cap or crown to reduce the chances that the tooth will break after the surgery.

Just add water and this squid-inspired plastic heals itself

While you’ve been busy scarfing down fried calamari rings, scientists at the University of Pennsylvania have been doing something else with squid . Namely? Studying the cephalopod’s ring teeth for a way to create a material that heals when water’s present , much in the way that those tentacle-bound choppers do. The way the report spotted by Popular Science tells it, the researchers were able to reproduce the type of proteins found in the self-healing squid teeth and trigger bacteria to make it in a lab environment. To test just how strong the new material was, the scientists formed the protein into the shape of a dog bone and cut it in two with a razor blade. After pressing the two segments back together, dousing them with a bit of water and applying pressure, the pieces fused and were still as strong compared to before they were cut. Like PopSci notes, this type of material could be used to coat things deep-sea internet cables or perhaps help biomedical devices have a longer lifespan, but is still a ways off from primetime. That and it still needs to be tested against shark bites , of course.

John Deere’s New Ride-On Mower Is One of the First To Have Airless Tires

Michelin and Bridgestone have been racing to take the air out of everyone’s tires—but in a good way. Both companies have been developing open-air wheels that will never puncture or deflate, and while they’ve mostly seen use in research and military vehicles to date, John Deere will finally offer a ride-on mower that uses Michelin’s see-through Tweels .

This Artificial Skin Can Feel Pressure, Heat and Dampness

Skin is complicated. Our body’s largest organ senses touch—but also temperature, pain, wetness, itching, and more. A new, stretchy artificial skin can pick up many of the sensations from the real thing, and it could someday cover a lifelike prosthetic hand. Read more…

DARPA Made a Vacuum the Size of a Penny

You know that terrible feeling in your gut when you’ve eaten something you shouldn’t have? Well imagine having a Roomba small enough to swallow, one that could clean up that mess inside you. That’s not exactly what DARPA had in mind when it funded the creation of this penny-sized vacuum , although it certainly should have been. Read more…

Google Now awarded Popular Science’s Innovation of the Year

Popular Science has given Google Now its “Innovation of the Year” award, putting it alongside past winners like the Large Hadron Collider , the Toyota Prius and the Mars Curiosity Rover . It’s august company to be sure, and the reasoning behind the decision is that it’s “the first virtual assistant that truly anticipates your needs.” The service has grown quite a bit since its initial launch — from personalized recommendations to public safety alerts and the addition of a pedometer , it seems that these are early days yet for the context- and location-aware app. Hit the Android G+ source link to read a Q&A between PopSci and part of the Google Now team to get some behind-the-scenes insight of the award-winning service.
