These 鈥榮pider silks鈥 also incorporate bioelectronics, so that different sensing capabilities can be added to the 鈥榳eb鈥.</p> <p> 探花直播fibres, at least 50 times smaller than a human hair, are so lightweight that the researchers printed them directly onto the fluffy seedhead of a dandelion without collapsing its structure. When printed on human skin, the fibre sensors conform to the skin and expose the sweat pores, so the wearer doesn鈥檛 detect their presence. Tests of the fibres printed onto a human finger suggest they could be used as continuous health monitors.</p> <p>This low-waste and low-emission method for augmenting living structures could be used in a range of fields, from healthcare and virtual reality, to electronic textiles and environmental monitoring. 探花直播<a href="https://www.nature.com/articles/s41928-024-01174-4">results</a> are reported in the journal <em>Nature Electronics</em>.</p> <p>Although human skin is remarkably sensitive, augmenting it with electronic sensors could fundamentally change how we interact with the world around us. For example, sensors printed directly onto the skin could be used for continuous health monitoring, for understanding skin sensations, or could improve the sensation of 鈥榬eality鈥 in gaming or virtual reality application.</p> <p>While wearable technologies with embedded sensors, such as smartwatches, are widely available, these devices can be uncomfortable, obtrusive and can inhibit the skin鈥檚 intrinsic sensations.</p> <p>鈥淚f you want to accurately sense anything on a biological surface like skin or a leaf, the interface between the device and the surface is vital,鈥 said Professor Yan Yan Shery Huang from Cambridge鈥檚 Department of Engineering, who led the research. 鈥淲e also want bioelectronics that are completely imperceptible to the user, so they don鈥檛 in any way interfere with how the user interacts with the world, and we want them to be sustainable and low waste.鈥</p> <p>There are multiple methods for making wearable sensors, but these all have drawbacks. Flexible electronics, for example, are normally printed on plastic films that don鈥檛 allow gas or moisture to pass through, so it would be like wrapping your skin in cling film. Other researchers have recently developed flexible electronics that are gas-permeable, like artificial skins, but these still interfere with normal sensation, and rely on energy- and waste-intensive manufacturing techniques.</p> <p>3D printing is another potential route for bioelectronics since it is less wasteful than other production methods, but leads to thicker devices that can interfere with normal behaviour. Spinning electronic fibres results in devices that are imperceptible to the user, but don't have a high degree of sensitivity or sophistication, and they鈥檙e difficult to transfer onto the object in question.</p> <p>Now, the Cambridge-led team has developed a new way of making high-performance bioelectronics that can be customised to a wide range of biological surfaces, from a fingertip to the fluffy seedhead of a dandelion, by printing them directly onto that surface. Their technique takes its inspiration in part from spiders, who create sophisticated and strong web structures adapted to their environment, using minimal material.</p> <p> 探花直播researchers spun their bioelectronic 鈥榮pider silk鈥 from PEDOT:PSS (a biocompatible conducting polymer), hyaluronic acid and polyethylene oxide. 探花直播high-performance fibres were produced from water-based solution at room temperature, which enabled the researchers to control the 鈥榮pinnability鈥 of the fibres. 探花直播researchers then designed an orbital spinning approach to allow the fibres to morph to living surfaces, even down to microstructures such as fingerprints.</p> <p>Tests of the bioelectronic fibres, on surfaces including human fingers and dandelion seedheads, showed that they provided high-quality sensor performance while being imperceptible to the host.</p> <p>鈥淥ur spinning approach allows the bioelectronic fibres to follow the anatomy of different shapes, at both the micro and macro scale, without the need for any image recognition,鈥 said Andy Wang, the first author of the paper. 鈥淚t opens up a whole different angle in terms of how sustainable electronics and sensors can be made. It鈥檚 a much easier way to produce large area sensors.鈥</p> <p>Most high-resolution sensors are made in an industrial cleanroom and require the use of toxic chemicals in a multi-step and energy-intensive fabrication process. 探花直播Cambridge-developed sensors can be made anywhere and use a tiny fraction of the energy that regular sensors require.</p> <p> 探花直播bioelectronic fibres, which are repairable, can be simply washed away when they have reached the end of their useful lifetime, and generate less than a single milligram of waste: by comparison, a typical single load of laundry produces between 600 and 1500 milligrams of fibre waste.</p> <p>鈥淯sing our simple fabrication technique, we can put sensors almost anywhere and repair them where and when they need it, without needing a big printing machine or a centralised manufacturing facility,鈥 said Huang. 鈥淭hese sensors can be made on-demand, right where they鈥檙e needed, and produce minimal waste and emissions.鈥</p> <p> 探花直播researchers say their devices could be used in applications from health monitoring and virtual reality, to precision agriculture and environmental monitoring. In future, other functional materials could be incorporated into this fibre printing method, to build integrated fibre sensors for augmenting the living systems with display, computation, and energy conversion functions. 探花直播research is being commercialised with the support of Cambridge Enterprise, the 探花直播鈥檚 commercialisation arm.</p> <p> 探花直播research was supported in part by the European Research Council, Wellcome, the Royal Society, and the Biotechnology and Biological Sciences Research Council (BBSRC), part of UK Research and Innovation (UKRI).</p> <p><em><strong>Reference:</strong><br /> Wenyu Wang et al. 鈥<a href="https://www.nature.com/articles/s41928-024-01174-4">Sustainable and imperceptible augmentation of living structures with organic bioelectronic fibres</a>.鈥 Nature Electronics (2024).

It鈥檚 not fully understood why some people appear to maintain better brain function than others, and how we can protect ourselves from cognitive decline.</p> <p>A widely accepted notion is that some people鈥檚 brains are able to compensate for the deterioration in brain tissue by recruiting other areas of the brain to help perform tasks. While brain imaging studies have shown that the brain does recruit other areas, until now it has not been clear whether this makes any difference to performance on a task, or whether it provides any additional information about how to perform that task.</p> <p>In a study published in the journal <em>eLife</em>, a team led by scientists at the 探花直播 of Cambridge in collaboration with the 探花直播 of Sussex have shown that when the brain recruits other areas, it improves performance specifically in the brains of older people.</p> <p>Study lead Dr Kamen Tsvetanov, an Alzheimer's Society Dementia Research Leader Fellow in the Department of Clinical Neurosciences, 探花直播 of Cambridge, said: 鈥淥ur ability to solve abstract problems is a sign of so-called 鈥榝luid intelligence鈥, but as we get older, this ability begins to show significant decline. Some people manage to maintain this ability better than others. We wanted to ask why that was the case 鈥 are they able to recruit other areas of the brain to overcome changes in the brain that would otherwise be detrimental?鈥</p> <p>Brain imaging studies have shown that fluid intelligence tasks engage the 鈥榤ultiple demand network鈥 (MDN), a brain network involving regions both at the front and rear of the brain, but its activity decreases with age. To see whether the brain compensated for this decrease in activity, the Cambridge team looked at imaging data from 223 adults between 19 and 87 years of age who had been recruited by the <a href="https://cam-can.mrc-cbu.cam.ac.uk/">Cambridge Centre for Ageing &amp; Neuroscience (Cam-CAN)</a>.</p> <p> 探花直播volunteers were asked to identify the odd one out in a series of puzzles of varying difficulty, while lying in a functional magnetic resonance imaging (fMRI) scanner, so that the researchers could look at patterns of brain activity by measuring changes in blood flow.</p> <p>As anticipated, in general the ability to solve the problems decreased with age. 探花直播MDN was particularly active, as were regions of the brain involved in processing visual information.</p> <p>When the team analysed the images further using machine-learning, they found two areas of the brain that showed greater activity in the brains of older people, and also correlated with better performance on the task. These areas were the cuneus, at the rear of the brain, and a region in the frontal cortex. But of the two, only activity in the cuneus region was related to performance of the task more strongly in the older than younger volunteers, and contained extra information about the task beyond the MDN.</p> <p>Although it is not clear exactly why the cuneus should be recruited for this task, the researchers point out that this brain region is usually good at helping us stay focused on what we see. Older adults often have a harder time briefly remembering information that they have just seen, like the complex puzzle pieces used in the task. 探花直播increased activity in the cuneus might reflect a change in how often older adults look at these pieces, as a strategy to make up for their poorer visual memory.</p> <p>Dr Ethan Knights from the Medical Research Council Cognition and Brain Sciences Unit at Cambridge said: 鈥淣ow that we鈥檝e seen this compensation happening, we can start to ask questions about why it happens for some older people, but not others, and in some tasks, but not others.

One in ten babies is born preterm in high-income countries; this can increase to almost 40% in low- and middle-income countries.</p>&#13; &#13; <p>Preterm babies are extremely vulnerable because they miss out on a crucial final developmental stage in which the hormone cortisol is produced and released exponentially into the unborn baby鈥檚 blood. Cortisol is vital to the maturation of organs and systems that are needed to keep the baby alive once born.</p>&#13; &#13; <p>For example, in the lungs, cortisol ensures that they become more elastic. This allows the lungs to expand so the baby can take its first breath. Without cortisol the new-born lungs would be too stiff, which leads to respiratory distress syndrome (RDS) and could be fatal.</p>&#13; &#13; <p> 探花直播established clinical treatment for any pregnancy threatened with preterm birth is glucocorticoid therapy, given via the mother before the baby is born and/or directly to the baby after birth. These synthetic steroids mimic the natural cortisol by speeding up the development of organs 鈥 including the lungs 鈥 which means the preterm baby is much more likely to survive.</p>&#13; &#13; <p>Lead author Professor Dino Giussani from the Department of Physiology, Development and Neuroscience at the 探花直播 of Cambridge said: 鈥淕lucocorticoids are a clear lifesaver, but the problem with steroids is that they speed up the maturation of all organs. For the baby鈥檚 lungs this is beneficial, but for the heart and circulation system it can be damaging 鈥 it resembles accelerated ageing.鈥</p>&#13; &#13; <p>A previous clinical study by Professor Paul Leeson鈥檚 laboratory at Oxford 探花直播 found that people who had been exposed to glucocorticoid therapy as unborn babies, via their mothers, showed measures of cardiovascular health typical of people a decade older.</p>&#13; &#13; <p>Cambridge researcher Dr Andrew Kane, involved in the rat study, thought that this accelerated ageing could result from steroids causing oxidative stress Steroids lead to an imbalance of molecules known as free radicals, which result in a reduction in nitric oxide. Nitric oxide is very beneficial to the cardiovascular system 鈥 it increases blood flow and has anti-oxidant and anti-inflammatory properties.</p>&#13; &#13; <p>To test if a lack of nitric oxide could be the origin of the adverse negative cardiovascular side-effects associated with glucocorticoid therapy, the researchers combined the steroid treatment with statins, which are widely used to lower cholesterol and are known to increase nitric oxide.</p>&#13; &#13; <p>Researchers gave the synthetic steroid, dexamethasone, combined with the statin, pravastatin, to rat pups. There were three other groups 鈥 one receiving dexamethasone alone, one receiving pravastatin alone and a control group that received saline.

It is led by the Pirbright Institute and the MRC- 探花直播 of Glasgow Centre for Virus Research.</p> <p>Researchers will work closely with experts at government agencies 鈥 the Animal and Plant Health Agency, UK Health Security Agency, and Defence Science and Technology Laboratory 鈥 to study the current outbreak and inform the public health response in the UK and internationally.</p> <p>Cambridge scientists Professor Geoffrey Smith from the Department of Pathology and Professor Mike Weekes from the Cambridge聽Institute for Medical Research and Department of Medicine are among the key scientists involved in the consortium.</p> <p>Professor Weekes said: "Monkeypox has become a really important global pathogen, reaching more than 50 countries worldwide in a matter of months. Although we have an effective vaccine and treatment, global roll-out has so far proved challenging, emphasising the importance of a comprehensive understanding of this virus. 探花直播UK consortium includes researchers from multiple different disciplines, and I anticipate the data we generate will rapidly help understand how the virus can be targeted in new ways to prevent disease."</p> <p>Professor Smith said: 鈥淔ew would have predicted that monkeypox virus would be causing a global epidemic in 2022. 探花直播ability to respond quickly to this new challenge has been helped greatly not just by the swift and welcome response of UKRI, but also by decades of support for the study of orthopoxviruses from UKRI and the Wellcome Trust. 探花直播information gained from those studies is valuable in the fight against monkeypox virus.鈥</p> <p> 探花直播monkeypox virus outbreak originated in West Africa. 探花直播current worldwide outbreak of cases spreading outside this area was first identified in May 2022. This is the first time that many monkeypox cases and clusters have been reported in non-endemic areas.</p> <p>In the UK there have been more than 3,400 confirmed cases since May, although case numbers are currently falling. Internationally, WHO reports it has spread to 106 countries and territories with 25 confirmed deaths.</p> <p>Professor Melanie Welham, Executive Chair of BBSRC, said: 鈥淥ne of the real strengths of the UK鈥檚 scientific response to disease outbreaks is the way that we can draw on leading researchers from all over the country, who can pool their expertise to deliver results, fast. Long-term support for animal and human virus research has ensured we have the capability to respond with agility.</p> <p>鈥淭his new national consortium will study the unprecedented monkeypox outbreak to better understand how to tackle it. This will feed rapidly into global public health strategies, developing new diagnostic tests and identifying potential therapies.鈥</p> <p> 探花直播consortium will focus on building our understanding in a number of key areas, including:</p> <p>Developing new tests and identifying potential control measures:</p> <ul> <li>Developing sensitive point-of-care tests to speed up diagnosis, such as lateral flow tests or LAMP* tests. 探花直播lateral flow test development will be conducted with Global Access Diagnostics (GADx) to develop a product which could later be manufactured at scale and used clinically worldwide, including in low/middle income countries.</li> <li>Screening potential drugs to treat monkeypox in human cells in the lab to determine which ones could be developed for further testing.</li> <li>Studying the virus, how it infects humans and its susceptibility to the immune response to identify targets for future therapies.</li> </ul> <p>Studying the virus:</p> <ul> <li>Characterising the genome of the virus and studying how it is evolving, and how this is linked to changes in the transmission and pathology of the virus.</li> <li>Understanding the human immune response to the virus and the vaccine, including studying samples from infected individuals.</li> <li>Identifying animal reservoirs and potential spill-over routes of transmission between animals and humans.</li> </ul> <p>Learning from the vaccine roll-out:</p> <ul> <li>Studying the effectiveness of the smallpox vaccine by tracking the immune responses after primary and secondary vaccination of up to 200 individuals.</li> </ul> <p>Professor Bryan Charleston, co-lead from 探花直播Pirbright Institute, said: 鈥 探花直播implications of the current monkeypox outbreak are huge. As well as tackling the current outbreak, we also need to be fully prepared for next outbreak, because worldwide there鈥檚 a huge reservoir of infection. One of the key ways we can do this is to develop rapid tests, which are very important to help clinicians on the front line to manage the disease.鈥</p> <p>Professor Massimo Palmarini, co-lead from the MRC- 探花直播 of Glasgow Centre for Virus Research, said: 鈥淢onkeypox is public health challenge, so taking decisive, collective action to better understand this virus is paramount. By bringing together research expertise in different areas, we will harness the UK鈥檚 world-leading knowledge to learn more about how the virus works and spreads and provide the foundations for the development of potential new treatments.鈥</p> <p><em>Adapted from a press release from UKRI</em></p> </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>Cambridge is among 12 institutions across the UK that will be working together to tackle the monkeypox outbreak, developing better diagnostic tests, identifying potential therapies and studying vaccine effectiveness and the virus鈥 spread.</p> </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">Few would have predicted that monkeypox virus would be causing a global epidemic in 2022</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Geoffrey Smith</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="https://www.gettyimages.co.uk/detail/photo/monkey-pox-cells-microscope-slide-royalty-free-image/1400375427" target="_blank"> BlackJack3D</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Monkeypox virus - 3D render</div></div></div><div class="field field-name-field-cc-attribute-text field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><a href="http://creativecommons.org/licenses/by/4.0/" rel="license"><img alt="Creative Commons License" src="https://i.creativecommons.org/l/by/4.0/88x31.png" style="border-width:0" /></a><br /> 探花直播text in this work is licensed under a <a href="http://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 International License</a>.
