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

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

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

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

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

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

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

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
