Imagine, if you will, a microscopic submarine, motoring around inside your blood vessels, delivering medicine, or perhaps performing surgery all on its own. This is the sort of future theoretical physicist Richard Feynman used to fantasise about, and yet today, we’re still stuck on the swimming part.   For a vessel at such a tiny

Scientists have created a super white paint that is the yin to Vantablack’s yang.  While ultra black materials can today absorb more than 99.96 percent of sunlight, this new super white coat can reflect 95.5 percent of all the photons that hit it.   Instead of warming up under direct light, objects painted with this

A major renewable energy project in Australia billed as the world’s largest solar farm in development has had its proposed location revealed. The AUD$20 billion facility – the heart of an ambitious electricity network called the Australia–ASEAN Power Link – will be built at a remote cattle station in the Northern Territory, roughly halfway between

Solar panels offer huge potential to move more people away from electricity generated from burning coal, and a new innovation devised by scientists stands to more than double the amount of light captured by conventional solar cells.   In a new study, a team of scientists from the UK, Portugal, and Brazil discovered that etching

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

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

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

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

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

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

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

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

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

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

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

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
