We already have devices which detect vehicles that are exceeding the speed limit, or that are too noisy. Now, scientists are working on an unmanned sensor that could be used to sniff out automobiles that are emitting overly-dirty exhaust.

This week DARPA kicks off a competition called the Subterranean Challenge, where hordes of robots are unleashed into caves and tunnels to test how well they can autonomously navigate these environments. One team's designs could lead to robots that explore caves on other planets.

Mercedes-Benz Classic, the restoration arm of Mercedes, has reconstructed the streamlined race car from 1932. The SSKL will be showcased at Pebble Beach as part of the event's "125 Years of Motorsport" theme. A 1938 Mercedes-Benz 320 n combination coupe (W 142) will also be shown.

A number of research groups around the world have already produced promising experimental versions of futuristic bandages that could take our healing game to the next level. Here’s a look at some of the more interesting examples.

The all-new Land Cruiser-based Desert Ops Supertourer is as delightfully retro as the limited edition X1-N Desert Ops camping trailer. It offers just the right blend of torque, cushion, utility and aggressive, dingo-spooking jewelry to pull the heavy-duty trailer anywhere it wants to go.

The FDA is again warning the public to avoid consuming a product called Miracle Mineral Solution (MMS). Despite over a decade of health warnings and cases of death, the sham product, which is essentially bleach, is still being consumed as a miracle cure for everything from autism to cancer and HIV.

A new study has discovered a mechanism explaining how obesity and high-fat diets can disrupt the appetite-suppressing signals from the brain and lead to overeating. The fascinating research revealed a hormone in the gut, triggered by high-fat meals, actually induces the body to keep eating.

Though there are just six fatal shark attacks each year globally, going for a swim off the back of a boat is not a pastime undertaken lightly. Now there's a scientifically-proven device which deters sharks and enables far safer ocean swimming. Is keeping the kids safe worth US$3,000?

A new study has used simulations to show that even Earth-like planets completely encased in ice could still have areas warm enough for life, muddying up the already-murky definition of habitable worlds.

​In the near future, it may be a lot more difficult to make computers believe that you're happy with something when you're actually not. That's because scientists at Britain's University of Bradford have developed software that can reportedly detect phoney smiles.

Ever receive a package and have nothing sharper than the keys in your pocket with which to open it? The Microblade Pill ensures you never experience that again. A different style of EDC, this mini tool won't filet fish or cut branches, but it will slice through packing tape and halve actual pills.

DLR is developing a new type of gyrocopter that ditches the pilot in favor of more cargo space. The focus of the Automated Low Altitude Air Delivery (ALAADy) system, the ALAADy Demonstrator unmanned gyrocopter is designed to autonomously deliver heavier cargoes at low altitudes.
