Stable lithium-sulfur battery could see smartphones run for 5 days

Posted on 10/01/2020

Batteries made with a lithium-sulfur chemistry rather than the typical lithium-ion hold a great deal of potential, and have for quite some time. Though they offer up to five times more energy per weight, one major roadblock has been a far shorter lifespan. An international team of scientists believes it has now overcome this hurdle through […]

App-controlled Fingerbot makes almost any device (slightly) smart

Posted on 10/01/2020

Nowadays you could kit out your entire house with smart devices – but that bill would stack up pretty quickly. It might be easier and cheaper to just retrofit the “dumb” appliances you already have with remote capabilities. Fingerbot is designed to do just that, and as the name suggests, it’s essentially a remote-controlled finger […]

Samsung’s take on the world of 2069

Posted on 04/09/201904/09/2019

Samsung is looking forward to what life might be like in the year 2069. The new report, called Samsung KX50: The Future in Focus, draws on the opinions of six of Britain’s leading academics and futurists to look at a range of new technologies that will affect people’s everyday lives. Trying to predict the future is […]

Rosy tech offers better, cheaper water purification

Posted on 10/06/2019

“Solar steaming” is an eco-friendly form of water purification in which sunlight is used to heat tainted water, turning it to steam which condenses back into liquid. That clean liquid is then collected as drinking water. A new system offers improved performance, and it copies the structure of the rose flower. Led by Assoc. Prof. […]

nVidia’s latest AI technology can instantly transform your doodles into photo-realistic scenes

Posted on 22/03/2019

Back in the early yo dawg/me gusta era of internet memes, around 2010, some larrikin made an image ridiculing how-to-draw books. “How to draw an owl,” it read. “First, draw some circles. Next, draw the rest of the [expletive] owl.” It beautifully skewered the giant leaps some of these how-to books would take between steps, […]

Scientists use liquid metals to turn carbon dioxide gas back into coal

Posted on 28/02/2019

If we’re going to curb the worst case scenario of climate change, it’s not enough to just cut back on future carbon dioxide emissions – we need to remove some of what’s already in the air. Capturing carbon from the air and sequestering it is emerging as a viable strategy, and now scientists have developed […]

CERN chip enables first 3D color X-ray images of the human body

Posted on 18/02/201918/02/2019

Medical X-ray scans have long been stuck in the black-and-white, silent-movie era. Sure, the contrast helps doctors spot breaks and fractures in bones, but more detail could help pinpoint other problems. Now, a company from New Zealand has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft […]

Omnidirectional urban wind turbine takes out 2018 James Dyson Award

Posted on 15/02/2019

Beating out a fascinating list of other entries, the O-Wind Turbine has taken out the UK£30,000 (US$39,000) first prize in this year’s James Dyson Awards. This crooked, vented spherical device is designed to hang from skyscraper balconies and generate electricity in the chaotic wind conditions of a high-rise metropolis. Traditional wind generators are very efficient, but […]

How brain scans can read your mind to reconstruct the face you’re thinking of

Posted on 08/02/201908/02/2019

It’s frustrating to have a clear mental image of something but not be able to exactly get it across in words or a drawing. Now, a team of neuroscientists from the University of Toronto Scarborough has developed a way to digitally recreate exactly the image someone is thinking about, by scanning their brain. So-called mind-reading technology is […]

Electricity-free air con: Thermoacoustic device turns waste heat into cold using no additional power

Posted on 30/01/201905/02/2019

Beginning with the principles of the Stirling engine, SoundEnergy’s THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling without requiring any other power source. This completely renewable technology could prove highly disruptive. The THEAC system uses no mechanical moving parts, no refrigerants, no […]
