The center of the exhibit is a giant radio tuner from the 1920s

If the 19th and 20th centuries were the Transportation Age, then the 21st century is the Information Age. Like most other ages, it didn't suddenly leap into being with the arrival of the Web or the smartphone – it has a history going back more than 200 years. The Science Museum in London is exploring this history in a new permanent exhibit called "Information Age: Six Networks That Changed Our World," which was recently opened by Queen Elizabeth II when she sent the first tweet by a British monarch.  Read More

CERN is currently digitizing over 50 years worth of its old black and white photographs to make them searchable via the Cern Document Server. However, the subject of many of the photos has been lost in the sands of time and the researchers can’t work out what’s what. If you know your Large Hadron Collider from your Low Energy Antiproton Ring, then be sure to read on and lend a hand ...  Read More

Researchers have used a DNA brick self-assembly method to build 32 different crystal struc...

The very same building blocks that make us have been successfully programmed to form 32 differently-shaped crystal structures. The structures feature a precisely-defined depth and a variety of sophisticated 3D nanoscale attributes, thereby laying further foundations for the use of DNA to revolutionize nanotechnology.  Read More

A light pulse fired from a 10 TW laser, dispersing into water vapor – the blue glow is las...

It's no secret that Star Wars is full of scenes that defy the laws of physics. From space battles inspired by WW I and II dogfights to beams of light clashing in lightsaber duels. The laser bolts fired from Han Solo's trusty blaster and Luke's X-wing also play by their own rules, traveling much slower than the speed of light and being perfectly visible in the vacuum of space. Researchers in Poland have now created a film to show what a laser bolt would actually look like.  Read More

Fiber optic sensors may help reduce the death toll in landslides, by providing an early wa...

Landslides kill thousands of people every year, so it should come as no surprise that various systems have been developed in an effort to predict when they're about to occur. One of the most recent innovations, developed by scientists at Italy's Second University of Naples, utilizes fiber optics to create a sort of watchable "nervous system" of the slope that's being monitored.  Read More

We're still a far cry from Star Trek's ship-towing and repelling technology, but laser physicists at the Australian National University (ANU) have built a tractor beam that can repel and attract objects. The beam moved spherical glass shells one fifth of a millimeter in diameter across a distance of up to 20 centimeters (7.87 in), which is around 100 times further than previous experiments at this scale, using only a single hollow laser beam that's bright around the edges and dark in its center.  Read More

Sugar kelp yields a lot of bio-oil – if you put the heat on (Photo: NOAA)

Biofuels may indeed offer a greener alternative to fossil fuels, but they do raise at least one concern – crops grown as biofuel feedstock could take up farmland and use water that would otherwise be used to grow crops for much-needed food. That's why some scientists have looked to seaweed as a feedstock. Kelp is particularly attractive, in that it's abundant and grows extremely quickly, although its fuel yields haven't been particularly impressive. That could be about to change, however, thanks to a newly-developed hydrothermal process.  Read More

Lockheed sees its compact fusion reactor as ready in 10 years

Fusion reactors are a bit like buses; you wait forever for one, then two come along at once. No sooner does the University of Washington announce that it’s working on a breakthrough compact fusion reactor (CFR) than Lockheed Martin says that its Revolutionary Technology Programs unit, AKA the Skunk Works, in Palmdale, California has one that could be ready for market within ten years.  Read More

Cigarette ash could now have another use besides ... well, nothing (Photo: Shutterstock)

In a perfect world, cigarette waste simply wouldn't exist. Given that it does, though, scientists have explored a number of methods of repurposing it – these have included using compounds from cigarette butts to store energy, make shipping pallets, and rust-proof steel. Now, researchers have shown that cigarette ash can be used as a low-cost means of filtering arsenic from water supplies. It's a little ironic, as cigarette smoke actually contains a dangerous amount of arsenic.  Read More

A new study by a team of scientists from Italy, France, Columbia University and the University of California, Berkeley, demonstrates that the Earth's magnetic field could change polarity in less than 100 years. The last magnetic reversal occurred some 786,000 years ago and was previously thought to have taken several thousand years but, if the researchers are right, the real time it may take for the flip to occur could actually be closer to the span of a human life.  Read More
