3D printed silver implants help tackle infections
3D printed silver implants help tackle infections
An interdisciplinary team of researchers from the University of Wolverhampton and the University of Sussex are investigating the possibility of 3D printing patient-specific silverbased implants to reduce infection and antimicrobial resistance. Despite substantial advances in invasive surgery and aseptic techniques, implant-related infection remains an all too common complication.

Care home study expanded to prevent COVID-19 spread
Testing the immune response of care home staff and residents to COVID-19 is to be expanded to help combat the spread of the virus among vulnerable people, as part of a UCL-led study. The Vivaldi 2 study will more than triple in size to provide a detailed picture of coronavirus infection in care homes in England.

Homeless adults nearly twice as likely to have heart disease
Homeless adults are 1.8 times more likely to have pre-existing cardiovascular diseases (CVD) compared to other adults, putting them at higher risk of severe coronavirus and early death, according to UCL researchers who have led the first large-scale study of its kind. The study, published in the European Heart Journal , used primary care data collected between 1998 and 2019 to compare 8,482 homeless individuals with 32,134 housed people who were matched by age and gender and lived in the same general practice area in UK.

Wearable imaging cap provides a window into babies’ brains
A team led by UCL researchers has demonstrated a new form of wearable, baby-friendly brain mapping technology that has important implications for understanding developmental conditions such as autism spectrum disorder and cerebral palsy. The technology uses harmless levels of red and near-infrared light delivered via a wearable cap to generate detailed 3D images of babies' brain activity.

Researchers to recover Europe’s lost smells
Scientists are using artificial intelligence (AI) to research past and present smells of Europe to identify and trace their link to language, places, cultural practices and emotions. The international research project, Odeuropa, has received ¤2.8m (£2.5m) of funding from the EU Horizon 2020 programme.

Rapid point-of-care testing during and after COVID-19 - how widely should it be used?
Even before the COVID-19 pandemic, the point-of-care testing industry was investing millions of pounds to develop rapid tests to tell us the cause of respiratory infections. The pandemic has accelerated this process. In an editorial published in the British Journal of General Practice today [17 November], researchers from the University of Bristol's Centre for Academic Primary Care ask if we know enough about these tests to merit their widespread use in primary care.

New green materials could power smart devices using ambient light
New green materials could power smart devices using ambient light
Researchers have developed environmentally friendly materials that could harvest enough energy from indoor light to power wireless smart devices. We are increasingly using more smart devices like smartphones, smart speakers, and wearable health and wellness sensors in our homes, offices, and public buildings.

Hole-punching bacteria could be engineered to attack pathogens
A team led by researchers at UCL and Imperial College London have discovered how to engineer bacteria that normally attack human cells so that they kill other pathogens instead. Many pathogenic (disease-causing) bacteria use specific proteins to punch holes in the cell membranes of their hosts, killing them.

New study could help to better predict which individuals are more susceptible to cancer-causing agents in the environment
New insights into the mechanisms behind how cancer-causing agents in the environment activate genetic recombination in DNA could help to explain some of the effects of exposure as well as predicting which individuals may be more susceptible to developing the disease, a new UK study has suggested. Everyone is exposed to low levels of carcinogens (substances or radiation that promote the formation of cancer) in the environment.

The Zayed Centre for Research celebrates first anniversary
With a vision to develop new treatments and cures for seriously ill children, the Zayed Centre for Research into Rare Disease in Children, is celebrating its first year of work and achievements. Run jointly by UCL and Great Ormond Street Hospital (GOSH) the purpose-built Zayed Centre for Research (ZCR) brings together pioneering research and clinical care under one roof - a world first for paediatric medicine.

Dieting and weight worries on rise in teens
Significantly higher numbers of Generation Z boys and girls in the UK are dieting to lose weight, and are likely to overestimate their own weight, finds a new UCL-led study. The research, published in JAMA Pediatrics , found that girls who are trying to lose weight are also more likely to experience depressive symptoms than in previous years.

UofG researchers report how novel diabetes drugs work to improve the prognosis for patients with heart failure
Scientists at the University of Glasgow have furthered the understanding of how novel diabetes drugs can improve prognosis for patients with heart failure. The results of the SUGAR-DM-HF trial - published in Circulation and presented to the American Heart Association - showed that the drug empagliflozin, originally a treatment for patients with type 2 diabetes, was able to significantly reduce the size of abnormally large hearts, which helps explain how they reduce the risk of hospitalisation and cardiovascular death in patients with heart failure.

Cysteine synthesis was a key step in the origin of life
In an important step during the early evolution of life on Earth, the formation of the amino acid cysteine delivered vital catalysts, which enabled the earliest protein molecules to form in water, according to a new study by UCL researchers. All proteins are built from the same 20 amino acids. One of these, cysteine, was assumed not to have been present at the origin of life.

Learning something new in lockdown? New research shows what could be happening in the brain
A study by scientists at the University of Sussex is challenging the common understanding of how mammalian brains work. The research, published in Current Biology, suggests that neurons in the sensory cortex don't just detect sensory information, but could actually decipher meaning and regulate bodily responses too.

The future’s uncertain - but noradrenaline can help us adapt
A brain chemical called noradrenaline is responsible for our responses to uncertain situations - helping us to learn quickly and adapt our behaviour, a new study has found. We found that a brain chemical called noradrenaline plays a role in our inability to predict the future when the state of the world is volatile.

Computer vision app allows easier monitoring of diabetes
Computer vision app allows easier monitoring of diabetes
A computer vision technology developed by University of Cambridge engineers has now been developed into a free mobile phone app for regular monitoring of glucose levels in people with diabetes. As someone with diabetes, this app makes the whole process easier. I've now forgotten what it was like to enter the values manually, but I do know I wouldn't want to go back to it James Charles The app uses computer vision techniques to read and record the glucose levels, time and date displayed on a typical glucose test via the camera on a mobile phone.

Analysis: Believing in conspiracies goes hand in hand with vaccine hesitancy
Dr Gul Deniz Salali, Lecturer in Evolutionary Anthropology and Medicine at UCL, discusses new research which confirms findings from before the pandemic that vaccine hesitancy often coincides with broader anti-scientific thinking. While developing an effective vaccine  probably won't  bring an immediate end to the pandemic, it's clear that things can't begin to return to normal without one.

Multiple simulations best for Covid-19 predictions
Computer modelling used to forecast Covid-19 mortality contains significant uncertainty in its predictions, according to a new study led by researchers at UCL and the CWI institute in the Netherlands. The authors of the study, performed for the Royal Society's RAMP initiative for Rapid Assistance in Modelling the Pandemic, highlighted that however well constructed such models are, they are only ever as robust as the "input" parameters - which include highly uncertain factors relating to how the disease is spread.
