The laptop turns 35

April 3, 1981 marked the introduction of the Osborne 1, the first mainstream portable computer. Three-and-a-half decades later, laptops are now much more portable – but how do they compare to the deeper vision that sparked them, and what lays ahead? Gizmag talks with Dr. Alan Kay, the personal computing visionary who came up with the notion of a notebook computer, and Lee Felsenstein, designer of the first commercially successful forerunner to the laptop, to get their views.Read More

Reaching for the stars: How lasers could propel spacecraft to relativistic speeds

How do you send man-made probes to a nearby star? According to NASA-funded research at the University of California, Santa Barbara (UCSB), the answer is simple: assemble a laser array the size of Manhattan in low Earth orbit, and use it to push tiny probes to 26 percent the speed of light. Though the endeavour may raise a few eyebrows, it relies on well-established science – and recent technological breakthroughs have put it within our reach.Read More

Micro-supercapacitors store energy directly inside a chip

Batteries are getting better at a steady pace, but the technology is far from perfect – they are still quite short-lived, and have real trouble delivering bursts of power. Now, researchers at Drexel and the Paul Sabatier universities have managed to embed mini supercapacitors directly inside a microchip to enable electronics that are even smaller, last longer, and have more power to feed on.Read More

First analysis of Earth-sized planet's atmosphere reveals surprises

Using instrumentation aboard the Hubble Space Telescope, astronomers have been able for the first time to detect and analyze the atmospheric composition of a distant super-Earth (a planet roughly the size of our own). The findings show that the planet's atmosphere is rich in hydrogen, carbon and helium, giving scientists important clues as to how such planets might have formed and evolved.Read More

Chance discovery puts graphene electronics closer to mass production

We've heard plenty on the wonderful properties of graphene, but the supermaterial par excellence still hasn't found its way to commercial products because it is too delicate for real-world conditions. Now, in a lucky and perhaps game-changing discovery, scientists at the Brookhaven National Laboratory (BNL) have found that placing graphene on top of common industrial-grade glass is a cheap and effective way of making it resilient and tunable, paving the way for the production of graphene-based electronics on a large scale.Read More
