First chip-to-chip quantum teleportation harnessing silicon photonic chip fabrication
The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society. For example, quantum computers may hold the key to solving problems that are too complex for today's most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from malicious attacks.

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.

Rebel robot helps researchers understand human-machine cooperation
In a new twist on human-robot research, computer scientists at the University of Bristol have developed a handheld robot that first predicts then frustrates users by rebelling against their plans, thereby demonstrating an understanding of human intention. In an increasingly technological world, cooperation between humans and machines is an essential aspect of automation.

Artificial skin creates first ticklish devices
A new interface developed by researchers in Bristol and Paris takes touch technology to the next level by providing an artificial skin-like membrane for augmenting interactive devices such as phones, wearables or computers. The Skin-On interface, developed by researchers in the Faculty of Engineering at the University of Bristol in partnership with Telecomm ParisTech and Sorbonne University , mimics human skin in appearance but also in sensing resolution.

Increase in online hate speech leads to more crimes against minorities
An increase in hate speech on social media leads to more crimes against minorities in the physical world, a study shows. Academics from Cardiff University's HateLab project collected Twitter and police recorded crime data from London over an eight-month period to analyse whether a significant association existed.

Artificial intelligence may be as effective as health professionals at diagnosing disease, finds study
Artificial intelligence (AI) appears to detect diseases from medical imaging with similar levels of accuracy as health-care professionals, according to research led by the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust. The research, the first systematic review and meta-analysis synthesising all the available evidence from scientific literature, was published today in The Lancet Digital Health .

Numbers limit how accurately digital computers model chaos
Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find UCL and Tufts University scientists. The study, published today in Advanced Theory and Simulations , shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread.

New technology to monitor anti-Polish hate online
Artificial intelligence is being used to tackle anti-Polish hate crime in the run up to Brexit. Researchers at HateLab, based at Cardiff University, are working with Samurai Labs, a Polish Artificial Intelligence laboratory, to monitor aggressive social media content and pinpoint any connections to offline events.

Anonymising personal data ’not enough to protect privacy’, shows new study
Current methods for anonymising data leave individuals at risk of being re-identified, according to new UCLouvain and Imperial research. Companies and governments downplay the risk of re-identification by arguing that the datasets they sell are always incomplete. Our findings show this might not help.

Generation and sampling of quantum states of light in a silicon chip
Scientists from the University of Bristol and the Technical University of Denmark have found a promising new way to build the next generation of quantum simulators combining light and silicon micro-chips. In the roadmap to develop quantum machines able to compete and overcome classical supercomputers in solving specific problems, the scientific community is facing two main technological challenges.

Businesses that embrace digital technologies are showing more resilience as Brexit uncertainty continues, report shows
New technologies are giving businesses in Wales a much needed boost while questions over Brexit continue, researchers say. Academics from Cardiff University's Welsh Economy Research Unit surveyed 479 small and medium enterprises (SMEs) as part of the 2018 Digital Maturity Survey. They say the results demonstrate a clear link between a business's success and its uptake of new digital opportunities.

Cancer treatment could become more effective thanks to computer algorithms
While network algorithms are usually associated with finding friends on social media, researchers at the University of Sussex have shown how they could also be used improve the effectiveness of cancer treatment, by predicting the interactions between genes. There are over 12 million newly diagnosed cases of cancer globally each year and this figure only continues to grow.

Artificial intelligence can predict premature death
Computers which are capable of teaching themselves to predict premature death could greatly improve preventative healthcare in the future, suggests a new study by experts at the University of Nottingham. The team of healthcare data scientists and doctors have developed and tested a system of computer-based 'machine learning' algorithms to predict the risk of early death due to chronic disease in a large middle-aged population.

Humans switch between apps in ’remarkably similar’ ways, scientists find
Humans are unknowingly adhering to a universal pattern when they flick between apps on their smartphones, scientists have discovered. Experts from Cardiff University have shown that although we spend a varying amount of time glued to our screens, the way in which we specifically switch between our different apps is remarkably similar.

Most laptops vulnerable to attack via peripheral devices, say researchers
Many modern laptops and an increasing number of desktop computers are much more vulnerable to hacking through common plug-in devices than previously thought, according to new research. It is essential that users install security updates to be protected against the specific vulnerabilities we have reported Theodore Markettos The research, to be presented today (26 February) at the Network and Distributed Systems Security Symposium in San Diego, shows that attackers can compromise an unattended machine in a matter of seconds through devices such as chargers and docking stations.

Artificial Intelligence could help to foil online dating scams
Dating apps and websites could soon use computing algorithms that 'think' like humans to pinpoint fake profiles designed to con victims out of thousands of pounds. Researchers from across the UK, including experts from the University of Bristol Cyber Security Group , have developed new algorithms that can understand what fake dating profiles look like and then apply this knowledge when they scan profiles submitted to online dating services.
