If you follow sports at all, then you've probably heard about athletes rupturing their ACL, or anterior cruciate ligament. It connects the femur to the tibia, and once it breaks, it's incapable of healing. Treatment most often involves reconstructing the ACL using grafts from the patellar tendon, which connects the patella (aka the kneecap) to the tibia – although this can present problems of its own. Now, scientists at Northwestern University in Illinois are creating a man-made replacement ACL, which could make treatment much more effective.  Read More

Ehang's Ghost Drone in action

It was just this June that we heard about the HEXO+ and AirDog drones, which were two of the first consumer multicopters to offer a Follow function – that's the ability to track the location of their user, and fly along above them. Since then, models including the Iris+ and Zano have come out with the same feature. Now, Chinese/American company Ehang is successfully raising production funds for its Follow-equipped GoPro-toting Ghost Drone. Developed in partnership with Duke University, not only is the quadcopter able to track and film its user, but it's also reportedly easier to fly than its competitors.  Read More

The EPFL sensor is capable of detecting movements made by microscopic living things, such ...

People often state that certain planets are too hot, cold or toxic to support life. The catch, however, is that those people are really just talking about life as we know it here on Earth. By that same token, when rovers exploring other planets seek out chemical signatures associated with life forms, they're only able to identify chemicals that we know to look for. That's why Swiss scientists from the EPFL research center have created a device that identifies microscopic life, based on nanoscale movements instead of chemistry.  Read More

They may be slow on land, but when they're in the water, sea turtles are fast and maneuverable – qualities that are also desirable in underwater robots. Additionally, the robotic equivalent of a turtle's streamlined shell could be stuffed full of electronic components and batteries. It shouldn't come as a surprise, therefore, that both ETH Zurich and the ARROWS project have recently created their own turtle-bots. Now, the National University of Singapore has announced its own entry in the field, that can self-charge its batteries while at sea.  Read More

Regine Gries has had to endure approximately 180,000 bedbug bites in the course of the res...

Having any amount of bedbugs in your home is not a good thing. The sooner that you know they're there, however, the easier it will be to exterminate all of them. With that in mind, scientists from Canada's Simon Fraser University have developed a method of luring the li'l bloodsuckers into traps, and then keeping them there so that their presence can be duly noted and addressed.  Read More

Samir Sadikov's 1st Prize-winning 'Dakar' concept

Although we've seen a lot of interesting ideas regarding what may be powering or guiding the cars of the future, it seems that those vehicles' tires don't fire the imagination in quite the same way. Korean tire manufacturer Hankook is trying to change that, however, with its Hankook Tyre Design Challenge. Here's a look at the student-submitted concepts that took the top prizes in this year's contest.  Read More

The Basic Version of the BiCi smart bike

If a new crowdfunding campaign is successful, yet another "smart bike" will soon be available to consumers. Called the BiCi, it was designed by a team from Shanghai-based AOAO Studio after a four-month period of focusing on "what the perfect bike should be." The end result certainly looks unique, if nothing else.  Read More

Most people probably don't think of a coating of paint as being a particularly major component of a manufactured item. If the object is quite large, however, or if a lot of them are being made, paint can add considerably to its weight and/or production costs. With that in mind, researchers from Harvard University's Laboratory for Integrated Science and Engineering have created a new lightweight, low-cost coloring technology for both rough and smooth surfaces.  Read More

The HexH2o can land on the water and shoot below the surface

Readers who checked out our recent article on the Seahorse human-powered airboat may have noticed something at least as impressive in the accompanying video – a camera-equipped quadcopter that can land on the water to shoot underwater footage. It's called the QuadH2o, and is made by a Thailand-based company of the same name. Now, that drone is about to be joined by a companion that sports another two propellers, along with some other extra features. It's time to say hello to the HexH2o.  Read More

The MOCAheart device, which can be mounted in an optional smartphone case

Your heart rate, blood oxygen level and blood pressure are all key indicators of your cardiovascular state of health. It would follow, then, that if you want to stay ahead of problems in that area, monitoring those parameters would be a great help. Well, that's just what MOCAheart is designed to do.  Read More
