Scientists in Japan have developed a paper-based sensor equipped with an array of extremely tiny microneedles, which they say can painlessly penetrate human skin for a quick and easy method of conducting diagnostic tests for conditions like pre-diabetes. Microneedles are super tiny-spikes so small they’re measured in micrometres (one thousandth of a millimetre), designed to

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

Synthetic gas, or syngas for short, is a crucial building block in the chemical manufacturing industry. Most people may never have heard of syngas, but every day it is used in the production of drugs, fertiliser, plastic, and biofuels. Unfortunately, even when syngas – a mix of hydrogen and carbon monoxide – is fermented to produce

So much of our everyday tech runs on batteries, the importance of lithium-ion rechargeables cannot be overstated. But they are expensive to produce, with difficult-to-source materials. There is an alternative - sodium-ion batteries have the potential to be cheaper and more easily produced, if we can get past the problem of getting these batteries to work

This summer, the clean energy company SINN Power is showcasing “the world’s first floating ocean hybrid platform” – a high-tech buoy that produces electricity from not one, not two, but three sources of renewable energy.  Using waves, wind, and the sun, the SINN Power floating structure, which can supposedly withstand waves up to six metres

A US Navy ship downed a flying drone with a “solid state laser” in the Pacific Ocean, the service branch announced on Friday. The USS Portland (LPD-27), a San Antonio-class amphibious transport dock ship, deployed its Technology Maturation Laser Weapon System Demonstrator (LWSD) against an unmanned aerial vehicle (UAV) last week during a demonstration, the

Our neurons talk in melodies; understanding their rhythms has proved key to creating a new device that could join their conversations. Just as glasses can aid our struggling eyes, the hope is that artificial brain matter could one day aid our brain bits that aren’t working as well as they could be. An international team

A tiny device called a micro-comb could one day replace existing internet infrastructure to hit crazy new highs in download speeds, providing millions with ample data at the same time, even during the busiest periods. The lightweight technology has recently been put to the test in a field trial that measured data rates of an

Here’s something you might not have expected to see Boston Dynamics’ robot dog Spot doing any time soon: herding sheep on a rugged New Zealand mountainside. The slightly bizarre sequence is part of a promotional video demonstrating Spot’s potential in the agricultural industry; it also includes footage of Spot checking on crops and clambering over

Cell phone towers across New Zealand are being set on fire and authorities believe the attacks are linked to the increasing proliferation of conspiracy theories connecting 5G networks to the coronavirus pandemic. As of May 18, 17 cell towers had been attacked in Auckland, Wellington, and Northland, causing hundreds of thousands of dollars in damage.

The chaos and uncertainty surrounding the coronavirus pandemic have claimed an unlikely victim: the machine learning systems that are programmed to make sense of our online behavior. The algorithms that recommend products on Amazon, for instance, are struggling to interpret our new lifestyles, MIT Technology Review reports. And while machine learning tools are built to

Scientists have developed a new type of self-assembling silver membrane that could be used to capture carbon dioxide (CO2) emissions before they have a chance to spread in the atmosphere. Using a technique the team says has never been attempted before, the researchers seeded their gas separation membrane with only a tiny deposit of the

Scientists are very keen to find effective ways of getting hydrogen from water, thus unlocking hydrogen’s potential as a clean fuel. A newly developed device manages the feat, using only sunlight as a power source. Using catalytic electrodes and perovskite solar cells fused together in a single unit, the clever contraption can hit sunlight-to-hydrogen efficiency

NASA engineers have designed a mass-producible ventilator tailored to coronavirus patients, and it could get emergency approval from the Food and Drug Administration by the weekend. A team of engineers at the Jet Propulsion Laboratory in Pasadena, California, designed and built the ventilator in just 37 days. The device, called VITAL as an acronym for

Whether you use Zoom, Skype or Microsoft Teams, the webcam on your home PC or laptop device has probably never been as active as it is during this pandemic. Most of us have a camera built into our phone, tablet, laptop, or a desktop webcam we use for work, study or virtual socialising. Unfortunately, this

Today, the world is grappling with more than just the climate crisis, and yet even now, in the face of a global pandemic, scientists are marching on with renewable solutions. Just this month, no less than three records have been broken in solar panel efficiency. The first and the second were achieved by scientists in

Much of the work undertaken by artificial intelligence involves a training process known as machine learning, where AI gets better at a task such as recognising a cat or mapping a route the more it does it. Now that same technique is being use to create new AI systems, without any human intervention. For years,

As quantum computers continue to grow in size and complexity, engineers are hitting a major obstacle. All of that added machinery means higher temperatures – and if anything can ruin a perfectly good quantum bit, it’s heat. There are a few possible solutions, but any fix needs to be small and compatible with existing silicon

You may have heard of Folding @ home, the number-crunching app you can run on your computer to help researchers tackle certain medical problems, including the new coronavirus. In the past month, the network of volunteers who’ve installed it has become so vast, the platform is outperforming the most powerful supercomputers in the world. According

Researchers working for industrial development company Carbios have created a mutant bacterial enzyme that can break down plastic bottles for recycling in only a couple of hours, according to The Guardian. The enyzme can break down PET plastic bottles into their individual chemical composites, which could later be reused to make brand new bottles. Conventional recycled

When the end of the world comes, how will you tweet? Thankfully for those of us who didn’t have a plan ready, Motherboard reports that software developer Virgil Dupras has built an operating system — Collapse OS — that can be run on parts salvaged from a post-apocalyptic hellscape. The idea is to find ways

Those Knightscope security robots may not be so great at their jobs. When a woman in a park near Los Angeles saw people fighting and tried to summon help via a police robot patrolling nearby, the robot merely told her to “step out of the way” and continued along its pre-determined route, according to NBC

A new gel-like fluid that sticks to vegetation for months on end could be an ingenious new way to stop mother nature from burning. Devised by an engineer and a former fire-prevention forester, this sprayable retardant could one day be used to drastically reduce the number of forest fires experienced each year. By coating vast

The bigger they come, the harder they fall, the old saying goes – or in this case, the more popular the game, the more user data is at risk, should hackers get access to it. That’s reportedly what’s happened with smash mobile hit Words With Friends. A hacker by the name of Gnosticplayers claims to

Tesla’s “Smart Summon” feature, which lets cars navigate themselves in parking lots, isn’t even out of beta yet. But Tesla owners are already using it in some mind-bogglingly stupid ways, Electrek reports. In a video uploaded to YouTube account “Dirty Tesla”, a Model 3 owner tries to walk in front of his vehicle while the

Autonomous driving will bring us a number of freedoms. Passengers will be able to watch movies, read newspapers – if they still exist – or play video games while the AI drives. But BMW thinks being chauffeured by a self-driving car can get a whole lot more exciting than that. The German carmaker released –

There is such a thing as not enough chaos. In a new study, scientists have discovered that complex calculations performed by computers can be off by as much as 15 percent, due to a “pathological” inability to grasp the true mathematical complexity of chaotic dynamical systems. “Our work shows that the behaviour of the chaotic

We’ve watched the Spot robot quadruped grow up and evolve, from its earliest days as a larger, more cumbersome beast to a carefully refined machine capable of pulling trucks. Now maker Boston Dynamics is putting the robo-dog on sale. The idea is not to provide a friendly pet that curls up in front of the

We just entered a fundamental new epoch in computing. Maybe. Google scientists said we did. Then their declaration mysteriously vanished. Last week, a scientific paper by Google and affiliated researchers was uploaded on a NASA website. Its contents – if legitimate – are not insignificant. In the paper, the scientists claim that quantum processors have
