Could Time Travel be Possible

As the common tropes of science fiction continue to break out into reality, from humanoid robots to self-driving cars, there’s one concept that has seemingly remained beyond our grasp: time travel

But, jumping through time might not be impossible, after all, according to one astrophysicist.

By the rules of theoretical physics, certain conditions exist that would allow for the construction of elaborate wormholes, which could transport humans back to different eras.

A wormhole could be constructed in a way that allows one end to remain nearly motionless, while the other moves at almost the speed of light. This could theoretically allow humans to travel through time. An artist's impression is pictured

Turkey Tech – Make Thanksgiving Easier

It’s that time of year again: turkey, mashed potatoes, cranberry sauce, pumpkin pie, the presence of friends and family, and a reason to give thanks for all of our good fortune in the last year.

Thanksgiving_Tech_s
If there’s one thing most of us want to NOT think about on Thanksgiving, it’s technology. Put the smartphones away, pack up the laptop, and disconnect for one day, right? Well, technology can actually help to bring us together on this most American of holidays, provided it’s put to good use instead of as a distraction from family time.

In a move that could revolutionize aerial combat, the US Air Force Research Lab (AFRL) has awarded Lockheed Martin a US$26.3 million contract to design, develop, and produce a high-power laser weapon that the AFRL wants to install and test on a tactical fighter jet by 2021. The new test weapon is part of the AFRL Self-protect High Energy Laser Demonstrator (SHiELD) program tasked with developing airborne laser systems. read more

After a record-breaking Kickstarter campaign and more than a year of painstaking design, testing and production work, Nura has finally gone into production with its first consumer headphones, and I’ve had my hands on a set for the last month. These are not press freebies, either – after playing with the prototypes last year, I immediately slapped down my own money for a set. That’s a first for me. read more

An international team of astronomers has discovered a temperate Earth-sized world with the potential to harbor alien life. The planet, known as Ross 128 b, is located a mere 11 light-years from Earth, and will one day become the closest exoplanet to our Sun, dethroning our current immediate neighbor exoplanet – Proxima b. read more

New AI can Enhance Pixelated Images

Researchers have unveiled a Blade Runner-style AI that can enhance pixelated images.

Dubbed EnhanceNet, the system relies on neural networks to boost the image quality, creating high-resolution images from a low-resolution input.

Stunning results shared in the study reveal how the new method can create sharper, more detailed results than traditional approaches, leading to photos that are nearly indistinguishable from the real thing.

Bell Helicopter isn’t known for indulging in concept aircraft, but it’s dipped its toes in the concept waters for the first time with the FCX-001. Unveiled at Heli-Expo 2017 in Dallas, Texas, the rotorcraft concept features an airframe crafted from sustainable materials, a hybrid power system, an artificial intelligence co-pilot, and morphing rotor blades that change to suit different flight conditions. read more

Weapon Wednesday – Tactical Gloves Keep You Warm and Dry

Keeping safe and comfortable in arctic conditions is a precarious balancing act between protecting one’s self against the cold without overheating. This is particularly true of a soldier’s hands and feet while working in the cold, so scientists from Stanford University and the US Army Natick Soldier Research, Development & Engineering Center are working on energized fabrics that heat up when powered, yet wick away sweat and dry easily. read more

There’s no doubt that nostalgia sells, and both the iconic Volkswagen Kombi and timeless Back to the Future movies have it in spades.

So maybe targeting a highly specific group of wealthy automotive aficionados that like both retro-Volkswagens and the Back To The Future movies isn’t as crazy as it sounds – or maybe it is. read more

In a step towards creating a new class of electronics that look and feel like soft, natural organisms, mechanical engineers at Carnegie Mellon University are developing a fluidic transistor out of a metal alloy of indium and gallium that is liquid at room temperature. From biocompatible disease monitors to shape-shifting robots, the potential applications for such squishy computers are intriguing. read more
