Blood clots during COVID-19 may be a cause of ongoing cognitive problems
High levels of two proteins at the time of COVID-19 have been found in patients who later experienced cognitive problems, including 'brain fog', giving a major clue as to one cause of their symptoms: blood clots. Dr Max Taquet and colleagues from the University of Oxford, along with the University of Leicester looked at blood tests from 1,837 people who had been hospitalised with COVID-19 to find potential proteins (biomarkers) associated with subsequent cognitive problems, with symptoms including serious and persistent problems with thinking, concentration and memory.

Deprived teens with poor learning skills at greatest risk from email scams
Disadvantaged teenagers are at greater risk of email scams and need better protection, according to an international study by a UCL researcher. The findings, published in the British Journal of Educational Studies , were based on more than 170,000 students aged 15 and show that one in five from low-income families or deprived areas could fall victim to phishing.

New research explores the link between baby birthweight, length of pregnancy and future cognitive problems
A new study has explored the link between infant birthweight, gestational age and future cognitive problems. Published today in JAMA Network Open, scientists have shown how the relative birthweight of infants associates with cognitive performance at five years of age. The results broadly indicate that a large birthweight is good for IQ, but this is relative to gestational age (the week of pregnancy the baby is born - for a healthy nine-month pregnancy this is 40 weeks).

Remote GP appointments as effective as in-person care for some conditions
Virtual GP and other primary care consultations can be as effective as face-to-face appointments for a range of health conditions. This is according to a new study by researchers at Imperial College London, published in the Journal of Medical Internet Research. It found health outcomes for patients who saw doctors remotely at least matched those for in-person care for mental illness, alcohol misuse, weight management and advice on quitting smoking.

A new study suggests boys who smoke in their early teens risk damaging the genes of their future children, increasing their chances of developing asthma, obesity and low lung function. Clinical Epigenetics is the first human study to reveal the biological mechanism behind the impact of fathers' early teenage smoking on their children.
Scientists use innovative techniques to map the environmental impact of Birmingham's Clean Air Zone Birmingham's clean air zone (CAZ) has reduced the levels of nitrogen dioxide gas (NO2) - an air pollutant which adversely affects people's health, a new study reveals. University of Birmingham scientists used an innovative technique to discover that during the CAZ's first seven months of operation, after correction for weather and seasonal effects, it resulted in 'modest, but significant' reductions in NO2 of up to 7.
Tracking drivers’ eyes can determine ability to take back control from ’auto-pilot’ mode
A team of UCL-led researchers has developed a new method to determine the attention levels of drivers and their readiness to respond to warning signals when using auto-pilot mode. The research, published in Cognitive Research: Principles and Implications , found that people's attention levels and how engrossed they are in on-screen activities can be detected from their eye movements.

Antibiotics promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill 'good' bacteria in the gut. This is according to new research led by Imperial College London scientists, which could lead to better patient risk assessment and 'microbiome therapeutics' treatments to help combat antibiotic-resistant bacteria.

Stopping the spread of viruses during surgeries using electric fields
Cardiff University research finds the use of an electric field, called electrostatic precipitation, could prevent aerosol spread of viruses during surgery with up to 99% efficiency - reducing the spread of viruses in healthcare environments and limiting surgery backlogs during future pandemics. It is estimated that hundreds of thousands of surgeries were delayed or cancelled to prevent the spread of covid during the pandemic, with aerosol-generating surgical procedures - such as laparoscopy or tracheostomy - at the highest risk of cancellation.

By monitoring the calls of spider monkeys, researchers have shown what level of human activity they will tolerate, helping guide conservation. The study, led by Imperial College London researchers, showed that Geoffroy's spider monkeys in Costa Rica are not found in areas with less than 80% forest cover and within one kilometre of a paved main road.
Kidney enzyme as a new target for treatment of high blood pressure
Persistent high blood pressure - or hypertension - can increase the risk of a number of serious and potentially life-threatening health conditions, such as heart disease, heart attacks and strokes. The team of researchers, funded by the British Heart Foundation , and supported by the National Institute for Health and Care Research (NIHR) Manchester Biomedical Research Centre (BRC) were investigating the kidney - the key organ responsible for the development of high blood pressure.

Unparalleled speed, capacity and reliability of new fibre broadband technology, invented by UCL researchers, could provide connectivity needed for applications of the future such as driverless cars and drone fleets. The study, published in Nature Electronics , describes how the new telecommunications technology, called frequency referenced multiplexing, could provide more than 20 times the capacity of the best full fibre broadband networks available and 65 times the speed of typical current UK home broadband, along with a near-guaranteed connection and low latency 1 .
Researchers have carried out a study to understand the psycho-social impacts of climate crisis on young people in the UK. The study found that distress over climate change is related to many difficult emotions in young people - even in the absence of direct climate-related experience. It can, though, also motivate them to take positive climate actions.
The new platform, called -MN-predict-, will allow doctors and scientists to identify those at risk and to design new treatments to prevent them from developing these potentially lethal cancers. MN-predict makes it possible to identify at-risk individuals, and we hope it can become an essential part of future leukaemia prevention programmes.
