Scientists claim that when you’re in fear or nervous, you shall be sweating a lot and they’ve made a device that is able to detect your fear from your smelly sweat. The scent signal contained in the sweat will tell if a person is scared. The scientists have carried out study on the underarm secretions of 20 terrified novice skydivers, and they have proven that the smell of the sweat reflected their fears.

The fear detector would be best used to identify terrorists or those who have committed wrongdoing at checkpoints. Currently, the researchers have got only a prototype of this device. They still have some obstacles to overcome such as it’ll not give reliable detection for those who wear perfumes or who with weird body odors.

It were the researchers from the Solheim Lab’s that actually showed what other use the 3D printers could be put to, by printing with ceramics. And now the University of Washington’s Solheim Rapid Manufacturing Laboratory has worked out a process to create glass objects using conventional 3D printers.

The typical 3D printing requires material to be powdered, say 20 microns thin, which when placed over a platform on the printer is picked by the binder to place only where required, thus binding the particles together and create the 3D object. Because glass doesn’t readily observe water – the researchers adopting a different approach had to alter the glassy powder adjusting the ratio to liquid. Here by mixing the powder with the binding material, and then heating, the researchers found the grind fused into an object.

Ronald Rael, an assistant professor of architecture at the University of California, Berkeley said,
“3-D printing in glass has huge potential for changing the thinking about applications of glass in architecture. Before now, there was no good method of rapid prototyping in glass, so testing designs is an expensive, time-consuming process. 3-D printing allows one to insert different forms of glass to change the performance of the material at specific positions as required by the design.”

Researchers from UC San Diego have successfully built integrated circuits that can operate perfectly in 125 degrees Kelvin, about minus 234 degrees Fahrenheit, a temperature as chilly that can be commercially created with liquid hydrogen. The integrated circuits are created with particles called excitons which can operate in extremely cold temperatures, as detailed by the physicists.

Researchers have a motive here to create excitons based devices which can efficiently work in room temperatures that have better of the current devices when it comes to interconnection speeds, owing to the excitons properties to be converted into light. This property gives the excitons based devices a faster and more efficient ability over the electronic devices with optical interfaces. If the UCSD researchers can work these integrated circuits with excitons to work in conditions we use our electronics, we could definitely be inching closer new type of superfast computer.

Wearing exoskeletons for a walk in the park seem a reality in years to come. Quite likely though, these wearable devices are for humans to attain that superhuman strength, and boy aren’t we’ll up to the status, just already. Thus, to send us more wandering in future, Engineers from Activelink have devised this powerful robotic exoskeleton suit that lets the wearer to lift 100 kilograms (220 lbs) with little effort.

The Power Loader suit as they call this is an imitation of the fictional hydraulic exoskeleton suit we’ve seen in the sci-fi classic Aliens. Built wearing an aluminum-alloy frame, the suit weighs 230kg and features motorized arms and power-legs and feet, so the exoskeleton functions around itself and doesn’t need to be carried like some of the others we have seen in the past. I’m waiting for the year 2015, when they say the Power Loader suit will be available. Video after the jump.
