The WristBow Mk II stores multiple carbon fiber darts in its ammo clip, which drop into pl...

When we last heard from German cyberpunk weapons hobbyist Patrick Priebe, he'd made a set of X-Men-inspired goggles that incorporated burning lasers. Some time before that, however, he showed us a wrist-mounted, laser-sighted crossbow that he'd created. Now, he's just completed a new-and-improved "semi-automatic" take on that crossbow.  Read More

A lab mouse body, one week after after the start of the PARS process – the arrow in the mi...

Ordinarily, when scientists want to see specific cells within a piece of biological tissue, they first have to remove that tissue from the body, slice it very thin, then examine those two-dimensional slices using a microscope. Imagine, though, if the tissue could be made transparent – seeing tagged cells within it would be sort of like looking at three-dimensional bubbles inside an ice cube. Well, that's just what a team at Caltech have done using a technique known as PARS, or perfusion-assisted agent release in situ.  Read More

Batteries for EVs like this Tesla Model S could be getting cheaper and more plentiful, onc...

If electric vehicles are to ultimately become as popular as Tesla hopes they will, then a whole lot of cost-effective batteries are going to be needed. That's why earlier this year, the automaker proposed a "Gigafactory" where it could crank out huge quantities of batteries. By making so many, it could drive down the price per battery via economy of scale. Yesterday, the company announced that it and Panasonic had signed an agreement to build that factory.  Read More

iPipet is an iPad app that uses glowing dots to guide lab techs as they're pipetting

If you've ever worked in a laboratory, or even if you've just seen them on TV, then you're probably familiar with the important but monotonous task of pipetting. To make it easier and less prone to errors, a team at the MIT-affiliated Whitehead Institute has created iPipet, an app that allows an iPad to visually guide "pipetters" in their work.  Read More

A GoRigIt prototype in use

Despite the ever-increasing popularity of the GoPro Hero actioncam, there's still not even one model of the darn thing that has a viewfinder. Users can buy a $70 add-on LCD screen, although if they're using a newer Hero, they can also just utilize its Wi-Fi connectivity to view the camera's output on their existing smartphone. The GoRigIt case makes it easier to take this approach, but joining the phone to the GoPro.  Read More

The nanoprop is able to easily pass between polymer chains, like those present in bodily f...

All over the world, scientists are creating microscopic "nanobots" for purposes such as delivering medication to precisely-targeted areas inside the body. In order for those tiny payload-carrying robots to get to their destination, however, they need some form of propulsion. Although some systems are already in development, a team of Israeli and German scientists may have come up with the most intriguing one yet, in the form of what they claim is the world's smallest propeller.  Read More

Scientists believe that a genetic mutation, which is detectable in blood samples, makes so...

While there are a wide range of scenarios that may cause a person to take their own life, the fact is that in a given situation, some people will do so whereas others won't. Scientists at the Johns Hopkins University School of Medicine now believe that this difference can largely be traced to a genetic mutation in the people who are more likely to commit suicide. What's more, this mutation can be detected via a blood test.  Read More

A Strike Cam video still of a bass checking out a lure

If you're a sport fisherman, then you know the frustration of having a fish strike and reject your lure. What sort of fish was it, and how big was it? Well, the Strike Cam may not help you land such finicky fish, but it can at least answer those questions.  Read More

Pensa/Horse Cycle's Merge is designed for the mean streets of New York City

Although many people may think of commuter bicycles as being the boring frumpy cousins to fancier road and mountain bikes, lately we've been seeing more and more models featuring all sorts of intriguing innovations for life on the streets. Recently, non-profit group Oregon Manifest invited five design firm/bike-builder teams representing five US cities to create prototypes of the ultimate such bike. Members of the public are being invited to vote for their favorite, with the winning bike getting produced commercially by Fuji Bicycles. Here's a look at the contenders.  Read More

A prototype of the pupillometer

Diabetic autonomic neuropathy is a condition that can occur in both type 1 and type 2 diabetics, compromising the autonomic nerves that control the gastrointestinal system, the heart and other vital organs. Among other things, it can cause arrhythmias, fainting, incontinence and an increased risk of bacterial infections. Thanks to a device being developed in Taiwan, however, it may soon be possible to detect the condition earlier, thus limiting its effects.  Read More
