New imaging system creates pictures by measuring time
A radical new method of imaging which harnesses artificial intelligence to turn time into visions of 3D space could help cars, mobile devices and health monitors develop 360-degree awareness. Photos and videos are usually produced by capturing photons - the building blocks of light - with digital sensors.

Using techniques learnt in astrophysics, researchers can now forecast drought up to ten weeks ahead
Researchers at the University of Sussex have developed a system which can accurately predict a period of drought in East Africa up to ten weeks ahead. Satellite imagery is already used in Kenya to monitor the state of pastures and determine the health of the vegetation using a metric known as the Vegetation Condition Index.

Shows how our brains remain active during familiar, repetitive tasks
New research, based on earlier results in mice, suggests that our brains are never at rest, even when we are not learning anything about the world around us. Finding coherent patterns in this large assembly of cells is challenging, much like trying to determine the behaviour of a swarm of insects by watching a random sample of individuals Timothy O'Leary Our brains are often likened to computers, with learned skills and memories stored in the activity patterns of billions of nerve cells.

AI could help improve performance of lithium-ion batteries and fuel cells
Researchers have demonstrated how machine learning could help design lithium-ion batteries and fuel cells with better performance. A new machine learning algorithm allows researchers to explore possible designs for the microstructure of fuel cells and lithium-ion batteries, before running 3D simulations that help researchers make changes to improve performance.

New technique may enable all-optical data-centre networks
A new technique that synchronises the clocks of computers in under a billionth of a second can eliminate one of the hurdles for the deployment of all-optical networks, potentially leading to more efficient data centres, according to a new study led by UCL and Microsoft. Data centres, comprising tens or hundreds of thousands connected servers, are the underlying technology empowering everything we do online, from storing films and photos to serving up webpages and online services.

AI reduces ’communication gap’ for nonverbal people by as much as half
Researchers have used artificial intelligence to reduce the 'communication gap' for nonverbal people with motor disabilities who rely on computers to converse with others. This method gives us hope for more innovative AI-infused systems to help people with motor disabilities to communicate in the future Per Ola Kristensson The team, from the University of Cambridge and the University of Dundee, developed a new context-aware method that reduces this communication gap by eliminating between 50% and 96% of the keystrokes the person has to type to communicate.

AI successfully used to identify different types of brain injuries
Researchers at Imperial College London and Cambridge have developed an AI algorithm that can detect and identify different types of brain injuries. The researchers found that their machine learning algorithm was able to detect, segment, quantify and differentiate between types of brain lesions using images of CT scans.

New microscopy technique helps pictures tell a thousand words
A new imaging method combined with machine learning uncovers previously hidden information in micrographs of biological cells to reveal quantitative information of gene expression levels. Researchers from the University of Glasgow's James Watt School of Engineering and School of Computing Science describe in a paper published today how they have used image analysis and machine learning as a tool to directly determine the gene activity in single cells.

Skin cancer diagnosis apps are unreliable and poorly regulated
Smartphone apps used as 'early warning systems' for skin cancer are poorly regulated and frequently cannot be relied upon to produce accurate results, according to new analysis by experts at the University of Birmingham. Skin cancer detection apps are designed to ensure that the right people seek medical attention by providing a risk assessment of a new or changing mole.

New system to detect cyber-attacks on smart devices in the home
A novel system capable of detecting and classifying cyber-attacks on smart devices around our homes has been developed by experts at Cardiff University. The system can distinguish between malicious or benign activity and detect attacks on devices such as the Amazon Echo Dot and Apple TV with a 90 per cent accuracy.

UK cyber security legislation ’crying out for reform’, new report finds
Far-right agitators in Portugal now have different reasons to their 1970s predecessors for becoming radicalised and committing acts of political violence - a new study shows. Influenced by the international 'skinhead' movement from the mid-1980s, current extremists drawn largely from the working classes have turned to violence to 'protect' white Portugal and Europe against the 'threat' posed by multi-racial and multicultural society.

Artificial intelligence used to predict 3D structure of proteins
A deep learning system can predict the structure of a protein using its genetic sequence more accurately than any previous modelling system, according to a study by researchers at DeepMind and UCL. Nearly every function our body performs relies on proteins. Predicting the intricate 3D structure of a protein is important because its structure largely determines its function and, once the structure is known, scientists can develop drugs that target this unique shape.

Undervolting allows attacks on Intel’s secure enclaves
Researchers at the University of Birmingham have identified a weakness in Intel's processors: by undervolting the CPU, Intel's secure enclave technology becomes vulnerable to attack. Modern processors are being pushed to perform faster than ever before - and with this comes increases in heat and power consumption.

Opinion: How the technology behind deepfakes can benefit all of society
Professor Geraint Rees, Pro-Vice-Provost of Artificial Intelligence at UCL, writes that AI can and must be used for good, to complement and augment human endeavour rather than replace it. Recent advances in deepfake video technology have led to a rapid increase of such videos in the public domain in the past year.
