The US military is getting its first new hand grenade in 40 years as engineers at the US Army Armament Research, Development, and Engineering Center (ARDEC) at Picatinny Arsenal, New Jersey, work on a safer multi-purpose design. Called the Enhanced Tactical Multi-Purpose (ET-MP) hand grenade, it will allow soldiers to choose between concussive or fragmentation blasts with the flip of a lever.
A self-driving Tesla comes with a hefty price tag, but a college student has given his Honda Civic similar abilities for a fraction of the cost.
Brevan Jorgenson has unveiled a device that replaces the rear-view mirror, which controls the brakes, accelerator and steering – and it only cost $700 to build.
The DIY device uses the hardware design and software shared online by Comma.ai last year, which had originally planned to upgrade cars with the technology.

The camera in the iPhone 7 Plus was deemed the ‘future of photography’ – but the technology set for the 10th-anniversary is said to be ‘revolutionary’.
An analyst has revealed that Apple is planning on implementing a front-facing camera with an infrared module that senses 3D space in the iPhone 8 handset.
This system could be used for a range of applications including, snapping a selfie that would be added to an augmented world, facial recognition or iris scanning.

The latest rumor regarding Apple’s iPhone suggests it will have a front-facing camera and infrared module that senses 3D space.
The sensors in the phone are said to detect the location and depth of objects around it.
The complete 3D system would send invisible IR light signals out from the phone and then wait for them to hit objects and return using the 1.4 megapixel IR receiver.
The camera would be used for a range of applications including, placing the user’s face on a character in a game, facial recognition, iris scanning and overall improved selfies.
Firearms have come a long way from the days of the musket and flintlock, but they’re also much more complicated and involve trade offs. In preparing for missions, soldiers are often forced to choose between a close quarter or a magnified sight for their assault rifles as there’s no one-size-fits-all solution.
The ancient art of origami has been inspiring engineers and designers for decades. The principles behind this Japanese folding technique have been appropriated by everyone from solar array designers for implementation in space to medical engineers creating ingestible robotics. Now a team at Brigham Young University (BYU) has created a lightweight bulletproof shield inspired by a Yoshimura origami crease pattern.
Levitation may look like magic, but there are a number of scientific tricks behind it. Magnetic systems are usually behind gimmicky consumer products like floating lightbulbs and speakers, optical levitation turns up in more academic pursuits like quantum computing, and acoustics could help suspend tiny particles to make better drugs. These techniques only work with certain objects, but researchers at the University of Chicago have developed a method to levitate basically anything, using differences in temperature.
“Magnetic levitation only works on magnetic particles, and optical levitation only works on objects that can be polarized by light, but with our first-of-its-kind method, we demonstrate a method to levitate generic objects,” says Cheng Chin, one of the researchers on the team.
Balls of ceramic, plastic and glass, ice particles, seeds and pieces of lint have been used to demonstrate the technique, and the team found that the levitated particles could be held aloft for over an hour rather than a matter of minutes, and wouldn’t wobble around sideways.
The researchers achieved this versatile levitation through the process of thermophoresis, which manipulates particles by placing them between sources of different temperatures. In this case, the objects were placed in a vacuum between two plates – the bottom one, made of copper, was left at room temperature, while the top plate contained liquid nitrogen, cooling a stainless steel container to -300º F (-184º C). The relative heat would flow from the bottom plate toward the top one, lifting the particles along with it.
Back in 2015, the Fiscal Times wrote an article describing a fear Bill Gates had. “He may be one of the world’s pivotal computing pioneers, mentioned in the same exuberantly geeky breath as Steve Wozniak, Steve Jobs, and Tim Berners-Lee. His technological exploits may have earned him over $80 billion, making him the world’s richest man. Yet even Bill Gates is somewhat concerned about the potentially destructive power of technology.”
Point of order. Some claim Gates is no longer the richest. That moniker goes to a Spaniard Amancio Ortega, the owner of the Zara retail chain.
The Nokia 3310 – one of the most popular cell phones in the world just after the turn of the millennium (along with its variations) – is having a surprising resurgence in popularity, amidst reliable rumors that Nokia will re-introduce a modernized version of the phone at the Mobile World Congress later this month.
Philadelphia University freshmen Charles Barilo, Peter Holderith and Zachary Samalonis were recently tasked with choosing a painting from those on display at the Philadelphia Museum of Art and creating a visual showpiece machine based on that painting which incorporated da Vincian thought processes. After a month of tinkering, they presented a cranked machine where sections of a topographical map are slowly raised when the handle is turned.
Forget sleeping pills. The latest insomnia cure comes in the form of a robot who you can curl up with to help you sleep through the night.
Dubbed Somnox, the peanut-shaped pillow measures your rate of breathing and then creates its own steady breathing rhythm in response.
Your body automatically picks up this breathing rhythm, helping you relax and drift off into a peaceful night’s sleep.
