Cars have gone from a “get me from point A to point B by burning gas” mode of transportation to a dream project for innovative techies. Cars can now run on electricity, be summoned by smartphone apps in cities all over the world, and are being developed to navigate without a human behind the wheel.
The next generation of mobile technology is coming our way. On Tuesday, Sprint announced plans to release a 5G smartphone by mid-2019. According to a company press release, the phone is a collaboration with LG Electronics.
Last week, a few miles off the northern coast of Scotland, a cylinder the size of a shipping container was carefully lowered to the bottom of the ocean floor. Sounds like a clever (if complex) way to bury evidence, or treasure, or something similarly mysterious.
Despite decades of ongoing research, scientists are trying to understand how the four fundamental forces of the Universe fit together. Whereas quantum mechanics can explain how three of these forces things work together on the smallest of scales (electromagnetism, weak and strong nuclear forces), General Relativity explains how things behaves on the largest of scales (i.e. gravity). In this respect, gravity remains the holdout.
Why do batteries die? And, why can they only be recharged so many times before they won’t hold a useful amount of charge? My young son asked me about that years ago when his battery-powered toy car stopped moving, wondering about what he called an “everlasting battery.” And this same question has probably crossed the mind of every cellphone user trying to send one last text before the screen blinks off.
You may have sworn off aerosol sprays in the ’90s when everyone was talking about the hole in the ozone layer, but a team of researchers from MIT has found a use for aerosols that could be good for both the environment and our health. This spray contains nanobots, tiny sensors with the potential to do everything, from detecting dangerous leaks in pipelines, to diagnosing health issues. They published their research in Nature Nanotechnology on Monday.
Thanks to virtual reality, you can swim with the dolphins, play some tennis, or spend some alone time, all from the comfort of your own living room. But it’s not yet perfect — a horrible wave of nausea can hit anytime, right in the middle of these activities.
Typically, engineers want to get bugs out of their creations. Not so for the U.K. engineering firm (not the famed car maker) Rolls-Royce — it’s looking for a way to get bugs into the aircraft engines it builds.
A BREAKTHROUGH. Researchers from Montreal’s National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking. Their device, called a spectral invisibility cloak, is the first to manipulate the color (or frequency) of the light waves that interact with an object, rendering it invisible.
AI has gotten pretty good at completing specific tasks, but it’s still a long way from having general intelligence, the kind of all around smarts that would let AI navigate the world the same way humans or even animals do.
The 50,000 ships sailing the sea at any one time have joined an ever-expanding list of objects that can be hacked. Cybersecurity experts recently displayed how easy it was to break into a ship’s navigational equipment. This comes only a few years after researchers showed that they could fool the GPS of a superyacht into altering course. Once upon a time objects such as cars, toasters and tugboats only did what they were originally designed to do. Today the problem is that they all also talk to the internet.
Spring construction season is underway, and many tons of concrete will be used in the coming months. Unfortunately, concrete is a brittle material: Placed under stress, it cannot bend very far before it fractures. Some pavements that are being poured now will crack within a few years and require expensive repairs. New concrete will be mixed, and the cycle will start again
Wind and solar energy are growing rapidly in the U.S. As these energy sources become a bigger part of the electricity mix, their growth raises new questions: How do solar and wind influence energy prices? And since power plants last for decades, what should policymakers and investors think about to ensure that investments in power infrastructure pay off in the future?
Researchers have demonstrated how infrared laser pulses can shift electrons between two different states, the classic 1 and 0, in a thin sheet of semiconductor. The technique could help to solve a major issue with quantum computing.
Hydrogen fuel cells were supposed to be the next big thing. Their promise peaked during the gas crisis of the 1970s as a clean energy source to power cars and electric plants, hydrogen fuel never truly took off.
Offshore oil rigs can be extremely dangerous places to work. Over the last few decades, several offshore explosions have led to environmental disasters and the death of workers. Regulations have so far failed to stop fatal accidents from occurring. But with developments in technology, particularly the rise of automation, we’re hoping that future accidents can be reduced.
If wearing a virtual reality or augmented reality headset is ever to become commonplace, hardware manufacturers will need to figure out how to make the devices small and lightweight while ensuring their images are sharp and clear. Unfortunately, this task faces a key limitation in optics: Conventional lenses are curved glass objects that focus different wavelengths of light in different locations, which would show viewers blurry images. As a result, pretty much anything with a lens – from tiny smartphone cameras to large-scale projectors – uses multiple lenses, which add weight, thickness and complexity, increasing cost.
Energy giant AGL this week unveiled plans to produce hydrogen power at its Loy Yang A coal station. But how do we transform coal, which is often thought of as simply made of carbon, into hydrogen – a completely different element?
If you’ve ever watched a modern blockbuster film, then you’ve almost certainly seen the magic of green screen compositing – or chroma keying – in action. The technique enables film and TV producers to record actors in front of a plain green backdrop, then replace the backdrop with special effects.
