There's an increasing recognition that passwords alone are not going be an adequate form of online security in the future. Two-factor authentication can vastly improve security, by simply introducing a second means of verification alongside a password. Google's new USB Security Key does just that.

Using a single display with a computer can be a bit restrictive, especially if you’re using lots of programs that need a lot of desktop space. LG's 34UM95-P monitor seeks to remedy this, either on its own or as a second screen. Gizmag spent a week with this monitor to see how it measured up.

Living in an area prone to flooding has historically meant that you need high sockets and deep pockets. Baca Architects, however, has come up with an altogether more ingenious solution. Its "amphibious house," designed to float on floodwater before being gently placed back down, is nearly complete.

The Dartz Prombron Black Shark is a battle-ready armored SUV built atop a Mercedes-AMG GL platform. It offers up to 1,500 bhp of roaring engine output combined with a unique scaly look and opulent interior

3D printers are very limited to the materials that they can use. Carvey takes a different approach. It's a desktop mounted, rapid-modelling, 3D carving device that can sculpt wood, plastic, and metal into almost any object that you care to design.

Vancouver Aquarium and US-based National Oceanic and Atmospheric Administration have begun using drones to keep tabs on endangered killer whales off the continent's west coast. The technology is giving the researchers a new perspective on the well-being of the animals.

Laser physicists at the Australian National University have made a tiny portion of science fiction a partial reality with a long-distance optical tractor beam that can repel and attract small objects up to 20 centimeters (7.87 in) through the air – and possibly much further.

Displaying the time via two banks of LEDs which are set using pulses of light delivered via the internet, the Type 50 is anything but a traditional timepiece. It's also powered by a AAA battery, to make it "immune to obsolescence."

A new low-cost flat panel light source with extremely low power consumption could pioneer a new generation of brighter, cheaper and greener lighting devices to rival the dominance of LEDs.

Getting experiment samples back from the International Space Station (ISS) is a logistical nightmare. Intuitive Machines' Terrestrial Return Vehicle (TRV) system may change that by making sending small payloads back to Earth as easy as mailing a parcel.

One of the many challenges facing engine designers is the need to constantly increase power outputs while simultaneously retaining or increasing efficiencies. Namikoshi Electronics of Japan believes its unique 4-in-1 concept engine could provide an alternative powerplant to the automobile industry.

Industrial robot arms are usually heavy and have high inertia. The alternative, delta arms, are lighter and faster but don't have the same degree of movement. To build a better mechanism, one inventor has created a robot that combines the lightness of one with the reach and flexibility of the other.
