Using X-rays, artificial intelligence and 3D printing, two UCL researchers reproduced a "lost" work of art by renowned Dutch painter Vincent Van Gogh, 135 years after he painted over it. PhD researchers Anthony Bourached (UCL Queen Square Institute of Neurology) and George Cann (UCL Space and Climate Physics), working with artist Jesper Eriksson, used cutting edge technology to recreate a long-concealed Van Gogh painting.

Engineers have created intelligent 3D printers that can quickly detect and correct errors, even in previously unseen designs, or unfamiliar materials like ketchup and mayonnaise, by learning from the experiences of other machines.

Is AI our only hope for the future of humankind? Professor Sami Kaski explores how this powerful tool could help meet the challenges facing our world. But how do we ensure that the human is present in the machine? Artificial Intelligence (AI) is all around us. From the smart watches we wear everyday collecting our personal biodata to helping medical professionals prescribe to patients, this technology has the potential to greatly advance global health services, to name just one area, in the future.

Researchers have designed smart, colour-controllable white light devices from quantum dots - tiny semiconductors just a few billionths of a metre in size - which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.

Using digital devices, such as smartphones, could help improve memory skills rather than causing people to become lazy or forgetful, finds a new study led by UCL researchers. The research, published in Journal of Experimental Psychology: General , showed that digital devices help people to store and remember very important information.

Researchers from the University of Glasgow have developed a new type of heat pump, a flexible heat pump technology, which could help households save on their energy bills and contribute towards net-zero emissions goals. Heat pumps are a low-carbon alternative to gas boilers. They draw energy from external low temperature sources, most commonly outdoor air, in order to heat indoor spaces.

A new form of flexible photodetector could provide future robots with an electronic skin capable of 'seeing' light beyond the range of human vision. A team of engineers from the University of Glasgow are behind the breakthrough development, which involves a newly-developed method of printing microscale semiconductors made from gallium arsenide onto a flexible plastic surface.

Even if global temperatures begin to decline after peaking this century because of climate change, the risks to biodiversity could persist for decades after, finds a new study by UCL and University of Cape Town researchers. The paper, published in Philosophical Transactions of the Royal Society B: Biological Sciences , models the potential impacts on global biodiversity if temperatures increase by more than 2°C compared to pre-industrial levels, before beginning to decline again.

Using sound to levitate something when there are other objects in the way has been shown for the first time by UCL researchers and could lead to advances in the manufacturing and entertainment sectors. The findings open up possibilities for more advanced interactive entertainment through virtual reality and mixed reality at theme parks, arcades and museums.

Current measures of digital technology use are not fit for purpose, say researchers. Questionnaires and scales measuring how we interact with smartphones, social media and gaming should not be used to demonstrate links with mental health and wellbeing, according to research from the Universities of Bath and Lancaster.

New gel technology could form a new type of treatment to help hearts regenerate after injury University of Manchester Researcher on (BHF) have developed a new biodegradable gel that can help to improve the delivery of cells directly into the living heart and could form a new generation of treatments to repair damage caused by a heart attack.

Since 2010 scientific papers written by remote collaborators are more likely to contain breakthroughs than single-location papers. This follows vast improvements in tools like Zoom (2012), Google Drive (2011) and Slack (2013). In an analysis of data for over ten million research teams, across eleven academic fields from 1961 to 2020, a new working paper from the Oxford Martin Programme on the Future of Work has determined that over the past decade remote collaboration between academic teams has led to more scientific breakthroughs.

Researchers have shown that the UK's existing copper network cables can support faster internet speeds, but only to a limit. They say additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all. We can improve speeds a little bit, but not nearly enough to be future-proof Eloy de Lera Acedo The researchers, from the University of Cambridge and BT, have established the maximum speed at which data can be transmitted through existing copper cables.

A new type of lightweight, 3D printed heat exchanger with a maze-like design is more compact and efficient than its conventional counterparts, its developers say. A team led by engineers from the University of Glasgow have developed the system, which exploits the unique properties of microscale surfaces to create a high-performance heat exchanger.

Medicines can be printed in seven seconds in a new 3D-printing technique that could enable rapid on-site production of medicines, reports a UCL-led research team. The findings published in the journal, Additive Manufacturing , improve the prospects of how 3D printers could be integrated into fast-paced clinical settings for on-demand production of personalised medicines.

Researchers at the University of Birmingham working in partnership with firms NitroPep Ltd and Pullman AC have developed new antimicrobial technology for air filters which can in seconds kill bacteria, fungi and viruses including SARS-CoV-2 - providing a potential solution to prevent the spread of airborne infections.

An object hidden below ground has been located using quantum technology - a long-awaited milestone with profound implications for industry, human knowledge and national security. University of Birmingham researchers from the UK National Quantum Technology Hub in Sensors and Timing have reported their achievement in Nature .

Researchers at the Centre for Sustainable and Circular Technologies have developed a new and simple method for upcycling plastic waste at room temperature. A new and simple method for upcycling plastic waste at room temperature has been developed by a team of researchers at the Centre for Sustainable and Circular Technologies (CSCT) at the University of Bath.

Cockatoos have shown an extraordinary ability to complete a task by combining simple tools, demonstrating that this cognitive ability is not found only in primates. According to researchers at the University of Veterinary Medicine in Vienna, the University of Birmingham, and the University of Vienna , the findings could shed new light on how our ancestors evolved the ability to design and use tools.
