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

You can tell a lot about a dolphin by its breath (Photo: Shutterstock)

If you want to get a picture of wild dolphin populations' health, it's typically necessary to capture some of the animals and then obtain blood samples or skin biopsies. Needless to say, it's hard work, and the dolphins tend not to like it. Soon, however, it may be possible to gather the same information using a device that samples their breath.  Read More

Using an enhanced LADAR (Laser Detection And Ranging) system, researchers at the National Institute of Standards and Technology (NIST) have created a long-range, laser-based imaging device that can generate high-definition 3D maps of objects at distances of up to 10.5 m (35 ft). The technology could find applications in precision machining and assembly, as well as in forensics where it could map evidence non-destructively.  Read More

In what are claimed to be new world records, two teams working in parallel at the University of New South Wales (UNSW) in Australia have each found solutions to problems facing the advancement of silicon quantum computers. The first involves processing quantum data with an accuracy above 99 percent, while the second is the ability to store coherent quantum information for more than thirty seconds. Both of these records represent milestones in the eventual realization of super-powerful quantum computers.  Read More

An array of nanoscale pillars ('nanograss') structure could make organic solar cells more ...

Researchers at the University of Massachusetts Amherst, Stanford University and the Dresden University of Technology have developed a long sought-after nanostructure that can significantly increase the efficiency of organic solar cells. Their "nanograss," a dense array of vertical nanopillars, can capture photons at a very high efficiency and could also lead to cheaper and more advanced 3D transistors, photodetectors and charge storage devices.  Read More

In the 21st century, the world lives with two futures ahead of it – one of looming energy shortages, and another of godlike energy abundance. The key to this whether it’s possible to turn fusion reactor technology from a laboratory exercise into a real-world application. Engineers that the University of Washington are working on a fusion reactor that, when scaled up, could produce energy on a practical scale, yet at a cost rivaling that of a conventional coal-powered plant.  Read More

According to Bonhams, around 200 of the Apple 1 computers were built and were the first pr...

We have previously argued here at Gizmag that the rate of technological advancement, which often banishes early iterations of a product to the realms of obsolescence, has obscured the true worth of some of our landmark innovations. As such, sales like the upcoming History of Science auction at Bonhams New York could provide fine opportunities for medium-term investments in rare collectibles, like a 1976 Apple 1 motherboard.  Read More

A new app can help turn your smartphone into a detector of cosmic rays thought to emanate ...

There are all sorts of apps available for smartphones to show atmospheric phenomena like wind speed, temperature, and rainfall along with other observations for tides and phases of the moon. But how about something really cool like an app for measuring the amount of interstellar cosmic radiation hitting the earth? A professor of physics from the University of Wisconsin thought that would be cool as well, and created an app to turn your smartphone into a cosmic ray detector that works in a similar way to those instruments found in high-tech observatories and mega-expensive laboratories.  Read More

Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.  Read More
