Our society faces the grand challenge of providing sustainable, secure, and affordable means of generating energy while trying to reduce carbon dioxide emissions to net zero around 2050. To date, developments in fusion power, which potentially ticks all these boxes, have been funded almost exclusively by the public sector. However, something is changing. Private equity

Many of us rely on GPS (Global Positioning System) to estimate travel times, find our way to new places, avoid traffic congestion, keep track of the kids, and generally avoid getting lost. But it’s not always the most reliable of systems, especially in built-up areas where it’s difficult to get a straight line of sight

Higher end AirPods have the potential to act as hearing aids for adults with mild to moderate hearing loss, according to new research that put the Apple-made earbuds up against traditional hearing aids in a series of tests. The findings could transform the lives of millions of people who don’t currently make use of hearing

The steady drum of a heartbeat is something that can easily fade into the background of our daily lives, with little thought given to the reliability of its pulse. But for those who develop an arrhythmia, the situation is much more fraught – their heartbeat is monitored and controlled by life-saving devices called pacemakers, which

Scientists continue to blow through data transmission records, with the fastest transmission of information between a laser and a single optical chip system now set at 1.8 petabits per second. That’s well in excess of the amount of traffic passing across the entire internet each second. Here’s another comparison: the average broadband download speed in

Scientists can now “decode” people’s thoughts without even touching their heads, The Scientist reported. Past mind-reading techniques relied on implanting electrodes deep in peoples’ brains. The new method, described in a report posted 29 Sept. to the preprint database bioRxiv, instead relies on a noninvasive brain scanning technique called functional magnetic resonance imaging (fMRI). fMRI

You might suppose Hollywood is good at predicting the future. Indeed, Robert Wallace, head of the CIA’s Office of Technical Service and the US equivalent of MI6’s fictional Q, has recounted how Russian spies would watch the latest Bond movie to see what technologies might be coming their way. Hollywood’s continuing obsession with killer robots

How many brain cells does it take to play a video game? No, really. That’s not a joke, and there isn’t a punchline. Instead, there’s a real actual answer, thanks to a neural network system called DishBrain. If that game is Pong, the number of brain cells is around 800,000. While their slow-moving, one-sided strategy

What if, as well as providing a fun way to enjoy our leisure time, video games could provide real benefits to our cognitive powers? That’s the promise of a new musical rhythm game that can not only teach drumming but also improve short-term memory. In a study of the game’s effects, 47 adults aged between

The vast number-crunching capabilities of artificial intelligence systems mean we can better predict the future of chaotic systems based on fewer and fewer patterns of the past – and a new algorithm is adding even more accuracy to the process. Developed through next-gen reservoir computing techniques, which take a more dynamic, speedier approach to machine

More than half of the digital data firms generate is collected, processed, and stored for single-use purposes. Often, it is never re-used. This could be your multiple near-identical images held on Google Photos or iCloud, a business’s outdated spreadsheets that will never be used again, or data from internet of things sensors that have no

The future of neural network computing could be a little soggier than we were expecting. A team of physicists has successfully developed an ionic circuit – a processor based on the movements of charged atoms and molecules in an aqueous solution, rather than electrons in a solid semiconductor. Since this is closer to the way

In one of the more unusual experiments we’ve seen recently, researchers attached a large pair of cartoonish googly eyes to the front of a small, self-driving vehicle – and it turns out that this kind of anthropomorphic tweak could actually improve pedestrian safety. A roving pair of peepers on the front of driverless vehicles could,

Scientists have created a robot that can transform from a black glob into a swarm of tiny beads and back again. The inventors say that the robot’s ability to split itself into many pieces and then snap back together makes it potentially useful for drug delivery. The human body is full of winding, narrow passages

We all know the routine by heart: “Please ensure your seats are in the upright position, tray tables stowed, window shades are up, laptops are stored in the overhead bins, and electronic devices are set to flight mode”. Now, the first four are reasonable, right? Window shades need to be up so we can see

It’s been easy to feel disconnected over the past two and a half years, despite all the hours spent doing Zoom trivia and online gaming with friends. But it turns out that, even when we’re physically alone, our brains may be able to sync up with the minds of others we’re playing with better than

Hydrogen has huge potential as a clean fuel: it’s abundant (mainly in compounds like water), it doesn’t produce any damaging emissions, and it can also be used to store energy from solar, wind, and tidal sources. There are challenges in producing enough of the stuff in a practical and affordable way, however. Splitting hydrogen from

Amid the continuous noise about cryptocurrencies, it’s often hard to pick out what really matters. However this month, if all goes to plan, the energy-hungry digital sector will undergo its biggest shake-up in years. Ethereum, the world’s second-largest cryptocurrency, is tomorrow expected to start a technology changeover which, once complete, should cause its carbon emissions

An expedition team has captured the highest quality footage of the Titanic, the iconic passenger liner that sunk in 1912 during her maiden voyage. The footage, which is the world’s first and only 8K video of the underwater wreck, shows “amazing detail” that will help marine archaeologists to study further the rate of decay of

You may not have given much thought to being able to text underwater, but for millions of scuba diving and snorkeling enthusiasts, communication in the ocean is pretty essential to staying safe. Right now, hand gestures are the preferred way of keeping in touch under the waves, and professional divers use a globally recognized vocabulary

We could one day charge our phones and tablets wirelessly through the air, thanks to newly developed technology. Researchers have used infrared laser light to transmit 400mW of light power over distances of up to 30 meters (98 feet). That’s enough juice to charge small sensors, though in time it could be developed to charge

Scientists have developed an ‘atomic television’ that uses lasers and atom clouds to carry a video signal that meets the traditional 480i resolution (480 horizontal lines) standard. Just don’t expect it to be installed as part of your home entertainment setup any time soon. Key to the technology is a glass container of gaseous super-sized

It isn’t alive, and has no structures even approaching the complexity of the brain, but a compound called vanadium dioxide is capable of ‘remembering’ previous external stimuli, researchers have found. This is the first time this ability has been identified in a material; but it may not be the last. The discovery has some pretty

First, they lost their front legs. Then, their hind legs. Now, all they can do is slither. It’s been around 100 million years since a trio of genetic tweaks deprived snakes of their ability to walk, and snake-lover and YouTube ‘fixer’ Allen Pan won’t have it any longer. “When any other animal has deformed legs,

While we’re not yet close to replicating the complexity and the intricacy of the human brain with anything artificial, scientists are making progress with certain dedicated devices – like a newly developed programmable resistor. Resistors can be used to make up analog neural networks in artificial intelligence systems, based on a structure designed to mimic

Earlier today, reports began emerging Google was down. While it has since returned, it once again highlights our dependence on technology service providers and shows how reliant many people are on a single operator for daily functions. There are few things we completely rely upon in our modern lives, but for many people, Google is

When mechanical engineering graduate student Faye Yap saw a dead spider curled up in the hallway, it got her thinking about whether it could be used as a robotics component. Turning dead spiders into mechanical grippers may be some people’s idea of a nightmare scenario, but it could have tangible benefits. Spider legs can grip

A digital twin is a copy of a person, product, or process that is created using data. This might sound like science fiction, but some have claimed that you will likely have a digital double within the next decade. As a copy of a person, a digital twin would – ideally – make the same

Scientists have unveiled a new printing process that can turn just about any piece of paper or cardboard into a waterproof keyboard that you can fold up and put in your pocket – and it doesn’t require a power source. The tech makes use of a special coating that’s repellent to liquids and dust, which allows

Plants have a seemingly effortless skill – turning sunlight into energy – and scientists have been working to artificially emulate this photosynthesis process. The ultimate benefits for renewable energy could be huge – and a new approach based on ‘photosheets’ could be the most promising attempt we’ve seen so far. The new device takes CO2, water, and sunlight

Of the many high expectations we have of quantum technology, one of the most exciting has to be the ability to simulate chemistry on an unprecedented level. Now we have our first glimpse of what that might look like. Together with a team of collaborators, the Google AI Quantum team has used their 54 qubit

In 2020, we’re sadly used to hearing how disinformation campaigns are being waged to influence people’s thinking, spread fake news, and further political agendas But the same tactics aren’t solely a threat in terms of long-term social manipulation, scientists warn. In a new study, researchers demonstrate that weaponised disinformation campaigns could also hypothetically be exploited to

The internet has transformed most areas of our lives over the last few decades, and the technology keeps improving: researchers just set a new record for data transmission rates, logging an incredible speed of 178 terabits per second (Tbps). That’s around a fifth faster than the previous record, set by a team of researchers in

The sound of a key sliding into a lock could be enough information to potentially create a copy of that key and open the lock – that’s the conclusion of researchers who’ve been investigating “acoustics-based physical key inference”. It makes sense, if you think about it: the clicks and clacks of a key pushed into

Scientists are ironing out the kinks for an ‘anti-solar power’ cell, one that can harvest energy at nighttime, even when the sun isn’t shining. Instead of absorbing light from the Sun and converting it into electricity, like a normal solar panel would, this type of technology works in reverse. At night, when there’s no incoming

The world could be headed for an ‘information catastrophe’ as the rate of production of digital bits continues to accelerate with no sign of stopping, new research suggests. In a new study – one firmly positioned in the more abstract quarters of theoretical physics, it must be said – researcher Melvin Vopson from the University

The world has a new brightest fluorescent material, and it’s the first of its kind. Rather than trying to improve fluorescent molecules, a team of chemists have developed a new material that preserves the optical properties of fluorescent dyes. This effectively prevents one of the biggest problems in producing fluorescent materials – the tendency of

Fourteen years after receiving the official go-ahead, scientists on Tuesday began assembling a giant machine in southern France designed to demonstrate that nuclear fusion, the process which powers the Sun, can be a safe and viable energy source on Earth. The groundbreaking multinational experiment, known as the International Thermonuclear Experimental Reactor (ITER), has seen components arrive in

We have developed four-winged bird-like robots, called ornithopters, that can take off and fly with the agility of swifts, hummingbirds and insects. We did this by reverse engineering the aerodynamics and biomechanics of these creatures. Our ornithopters have the potential to outperform and outmanoeuvre existing drone configurations with static wings or propellers. What are ornithopters?

US officials and scientists have begun laying the groundwork for a more secure “virtually unhackable” internet based on quantum computing technology. At a presentation Thursday, Department of Energy (DOE) officials issued a report that lays out a blueprint strategy for the development of a national quantum internet, using laws of quantum mechanics to transmit information

If doomsday comes, know this: precautions have been taken. On an isolated Arctic archipelago, the Svalbard Global Seed Vault – aka Norway’s ‘Doomsday Vault’ – holds over 1 million seed samples in a fortress-like bunker designed to be the most invulnerable seed bank in the world. Svalbard protects more than just seeds, though. On the

Social media platforms like Facebook, Twitter and Instagram started out as a way to connect with friends, family and people of interest. But anyone on social media these days knows it’s increasingly a divisive landscape. Undoubtedly you’ve heard reports that hackers and even foreign governments are using social media to manipulate and attack you. You

While artificial intelligence systems continue to make huge strides forward, they’re still not particularly good at dealing with chaos or unpredictability. Now researchers think they have found a way to fix this, by teaching AI about physics. To be more specific, teaching them about the Hamiltonian function, which gives the AI information about the entirety

By making use of the ‘spooky’ laws behind quantum entanglement, physicists think have found a way to make information leap between a pair of electrons separated by distance. Teleporting fundamental states between photons – massless particles of light – is quickly becoming old news, a trick we are still learning to exploit in computing and encrypted communications

The list of the fastest 500 supercomputers in the world just got updated again, and there’s a new number one: the Fugaku supercomputer built by the RIKEN Institute and the Fujitsu tech company in Japan. IBM’s Summit supercomputer has been comprehensively pushed into second place, because Fugaku can crunch through 415.5 quadrillion computations per second (also

Stripped of any fancy circuitry and complex layers of higher order thinking, the nervous system is little more than a calculator for making smart choices. Food is good, but what if it’s toxic? Empty calories won’t give you energy, but what if they’re satisfying? To better study how a rudimentary brain deals with decisions between

For the first time, US doctors can prescribe a video game. The Food and Drug Administration (FDA) has just approved EndeavorRX as an effective treatment for kids with attention deficit hyperactivity disorder, or ADHD. Children aged 8-12 years old can now be prescribed gaming sessions on EndeavorRX, in which players pilot a small aircraft through

Artificial intelligence networks have learnt a new trick: being able to create photo-realistic faces from just a few pixelated dots, adding in features such as eyelashes and wrinkles that can’t even be found in the original. Before you freak out, it’s good to note this is not some kind of creepy reverse pixelation that can
