It can be hard enough for parents to maintain a cool head when dealing with an angry child at the best of times, but things can get much more difficult when that child has ADHD (attention deficit hyperactivity disorder). That's why scientists at Microsoft Research and the University of California, San Diego have created ParentGuardian. It combines a wrist-worn sensor and an app, to monitor parents' stress levels and deliver real-time coping strategies.  Read More

The Runbell is designed to let runners alert walkers to their presence, without having to ... Although some urban cyclists may think that bike bells are fussy and unnecessary, those of us who use them will tell you that they're much easier and less confrontational than yelling "On your left!" at pedestrians. Well, the Runbell is designed to let runners in on the bell action.  Read More

The autonomous Land Tamer vehicle, which will be dropped off to explore a rugged area by a...

This April, Sikorsky Aircraft Corp and the US Army used a one-of-a-kind autonomous Black Hawk helicopter to perform an unmanned cargo flight demonstration. Known as the Optionally Piloted Black Hawk (OPBH) Demonstrator, that same chopper has now been enlisted to take the autonomy concept even further. In the new Extended Operational Reach with Autonomous Air and Ground Vehicles project, it will deliver an all-terrain vehicle to a remote site, and that vehicle will then autonomously explore the site from ground level.  Read More

A MagnetoSperm in action

When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm.  Read More

Scientists have used lasers to gauge the alcohol vapor content of the air in moving cars  ...

It used to be that the only way you could get a speeding ticket was if a police officer personally witnessed your overly-fast driving. Then photo radar came along. Well, when it comes to drunk driving, lasers could soon be the equivalent of photo radar. Polish researchers at the Military University of Technology in Warsaw have demonstrated how the high-intensity beams of light can be used to detect the presence of alcohol – even exhaled alcohol – in passing vehicles.  Read More

Although it's now possible to create lab-grown cartilage, there's still at least one big challenge in doing so – cartilage grown in a flat Petri dish may not be optimally-shaped for replacing the body's own natural cartilage parts. Scientists from a consortium of UK universities, however, are developing a possible solution. They're using "ultrasonic tweezers" to grow cartilage in mid-air.  Read More

The 'head' of the WatchStander system, incorporating a video camera and a 12 million candl...

Today's ships are equipped with radar systems that let them identify other ships from a distance, and while that works well enough for collision avoidance, those systems aren't the greatest at detecting small watercraft ... such as the low-slung skiffs often used by pirates. That's where WatchStander comes in. It's a radar system that's designed to pick out such boats, and then deter their crews before they can attack.  Read More

The PetPace collar tracks your pet's vital statistics

One of the challenges in monitoring the health of our pets lies in the fact that they can't tell us when they're starting to feel a little poorly. We generally only know that there's something wrong once it's progressed to the state that it's really obvious. The PetPace collar is designed to let pet owners know that something's up, before it reaches that point.  Read More

The Flatev makes fresh-baked tortillas from individual dough pods Say what you will about the wastefulness of Keurig coffee-makers, you've gotta admit that the things are convenient – you just stick a K-Cup in the top, and a single serving of coffee comes out the bottom. Well, inventor Carlos Ruiz is now hoping to bring that same convenience to freshly-baked flatbreads, with his Flatev tortilla-maker.  Read More

Prof. Diane Beauchemin analyzes hair in her lab (Photo: Anne Craig)

If you watch any cop shows, then you know that a person's race and gender can be determined by doing a DNA analysis of one of their hairs. Now, however, Canadian scientists at Queen's University have developed a method of obtaining that same information from hair samples, that's quicker than DNA testing and is 100 percent accurate.  Read More
