For the first time ever, scientists have stored light-based information as sound waves on a computer chip – something the researchers compare to capturing lightning as thunder. While that might sound a little strange, this conversion is critical if we ever want to shift from our current, inefficient electronic computers, to light-based computers that move

Last week, scientists made headlines around the world when news broke of an artificial intelligence (AI) that had been trained to determine people’s sexual orientation from facial images more accurately than humans. According to the study, when looking at photos this neural network could correctly distinguish between gay and heterosexual men 81 percent of the

Perhaps among all clean energy alternatives, nothing can be as clean as hydrogen. Burning hydrogen in fuel cells produces only water as a byproduct. In that sense, it’s also truly renewable. Yet, manufacturing hydrogen fuel cells on a larger scale hasn’t been that easy, primarily because fuel cells require rather complex and, until recently, expensive materials.

Humans before animals and property. No discrimination as to who should survive. Safeguards against malicious hacking. These are just some of the world-first ethical rules being implemented in Germany regarding how autonomous vehicles are to be programmed.   The federal transport minister Alexander Dobrindt presented a report on automated driving to Germany’s cabinet last month.

Gravitational lensing is a curious phenomenon. Not only does it demonstrate properties associated with the invisible dark matter, gravitational lensing is a distortion or bending of spacetime that was one of the predictions in Einstein’s general theory of relativity. Due to their uniqueness and what they can tell us about the universe, astronomers continue to study

They’re calling it laser streaming. No, it’s not a new sport or some Netflix-like pastime. Instead it’s a new observable phenomenon involving fluids and laser beams. Thanks to engineers from the University of Houston (UH) in Texas, we’ve now realised that it’s possible for highly focused, beams of light – aka lasers – to transfer its momentum to create

Scientists have developed a thin flexible battery suited to implantable devices that does away with dangerous chemicals and replaces them with biologically compatible liquids. The bendy batteries use sodium-based liquids – one a saline solution and another using cell cultures – and this innovation could change how we power wearable devices and even medical implants.

If you have seen or read The Martian, you may recall the stranded astronaut converting a hydrogen-based fuel into water. Well, we may have just discovered material that easily reverses this process. Researchers at the US Army Aberdeen Proving Ground Research Laboratory were developing a high-strength aluminium alloy when they made a startling discovery. During routine testing of
