Declining eyesight improved by looking at deep red light
Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans. Scientists believe the discovery, published in the Journals of Gerontology , could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.

Brain complications in patients with severe COVID-19
Neurological and psychiatric complications observed in critically ill patients during the early days of the COVID-19 pandemic, shine new light on conditions which may be linked to coronavirus, finds new research co-led by UCL. The study, published in the Lancet Psychiatry , describes 153 patients treated in UK hospitals, who were deemed by doctors to represent the most severe cases.

Third of people report enjoying lockdown
On balance a third of people in the UK have been enjoying the lockdown, while 46% have not been enjoying it and 21% have mixed feelings, finds UCL's Covid-19 Social Study. The research also shows that 17% of people have not been enjoying lockdown 'at all', whilst only 4% of people have been enjoying it 'very much'.

Shelling out for dinner: dolphins learn foraging skills from peers
Shelling out for dinner: dolphins learn foraging skills from peers
A new study demonstrates for the first time that dolphins can learn foraging techniques outside the mother-calf bond - showing that they have a similar cultural nature to great apes. The findings, led by an international research team including academics at the University of Bristol, are published in Current Biology.

Bristol part of largest global study on impact of COVID-19 across 129 countries
The COH-FIT (Collaborative Outcomes study on Health and Functioning during Infection Times) is an online survey project to identify risk and protective factors that will inform prevention and intervention programmes for the COVID-19 pandemic, and if other pandemics occur in the future. The study, led by clinicians Professor Christoph Correll from the US and Dr Marco Solmi from Italy, aims to collect data from around 100,000 participants.

Does fossil study prove iconic sabretooth was really a ’pussycat’
Not all sabretooth cats were fearsome predators - some may have been scavengers using their teeth to rip open carcasses before extracting their prey's innards with a big tongue, according to a new study. Thylacosmilus atrox lived some five million years ago in Argentina - a jaguar-sized marsupial with huge canines, fuelling speculation it was an even more vicious predator than placental carnivores, such as the North American Smilodon fatalis, that it superficially resembled.

Scientists develop model that reproduces photosynthesis
An international team, led by the University of California (Riverside) in collaboration with scientists from the Universities of Glasgow and Amsterdam, has constructed a model that reproduces a currently unrecognized general feature of photosynthesis, that can be observed across many types of photosynthetic organisms.

Antibody tests may help detect COVID-19 infection - if used at right time
Scientists have analysed data from around the world to examine the accuracy of antibody tests for COVID-19, and have shown that the timing of testing is critical. The tests do not work accurately when administered at the wrong time. In the most comprehensive review of its kind of COVID-19 testing, researchers have examined all available test accuracy evidence for antibody tests published up to the end of April.

Air pollution could help London transport planners fight COVID-19
Measuring air quality across London could help fight COVID-19 by providing a rapid means of deciding whether to reduce public transport movement - given strong links between exposure to air pollution and COVID-19 transmission, a new study reveals. Analysis of air pollution, COVID-19 cases and fatality rates in London demonstrates a connection between increased levels of nitrogen dioxide (NO2) and particulate matter (PM2.5) and higher risk of viral transmission.

AI could help improve performance of lithium-ion batteries and fuel cells
Researchers have demonstrated how machine learning could help design lithium-ion batteries and fuel cells with better performance. A new machine learning algorithm allows researchers to explore possible designs for the microstructure of fuel cells and lithium-ion batteries, before running 3D simulations that help researchers make changes to improve performance.

Resource curse or resource blessing: How major oil discoveries keep autocrats in power
Resource curse or resource blessing: How major oil discoveries keep autocrats in power
Oil is the most effective natural resource when it comes to keeping despots in power, new research shows. Oil is a more useful resource for rulers looking to hold onto power than minerals such as copper, nickel or zinc but its' benefits are felt most strongly more than a decade after a discovery is made, according to new research led by the University of Sussex Business School.

Economic impact of Covid-19 compounding existing inequalities in Wales, report finds
Wales's lowest earners were ten times more likely to have been affected by the Covid-19 shutdown than those on the highest salaries, research shows. The briefing paper from Cardiff University's Wales Governance Centre says almost half of those bringing home the smallest incomes were working in jobs that were forced to stop due to the lockdown.

Genomes front and centre of rare disease diagnosis
Cambridge-led study discovers new genetic causes of rare diseases, potentially leading to improved diagnosis and better patient care. This research shows that quicker and better genetic diagnosis will be possible for more NHS patients Willem Ouwehand A research programme pioneering the use of whole genome sequencing in the NHS has diagnosed hundreds of patients and discovered new genetic causes of disease.

Reveals how water in the deep Earth triggers earthquakes and tsunamis
Water (H2O) and other volatiles (e.g. CO2 and sulphur) that are cycled through the deep Earth have played a key role in the evolution of our planet, including in the formation of continents, the onset of life, the concentration of mineral resources, and the distribution of volcanoes and earthquakes.

Healthy new tissue can be ’printed’ using innovative technique
New muscle has successfully been created in mice using a minimally invasive technique dubbed 'intravital 3D bioprinting' by a team involving UCL scientists. This new research could pave the way for minimally invasive surgical techniques for organ repair and reconstruction that could remove the need for transplantation in children with complex conditions.

Bacterial predator could help reduce COVID-19 deaths
A type of virus that preys on bacteria could be harnessed to combat bacterial infections in patients whose immune systems have been weakened by the SARS-CoV-2 virus that causes the COVID-19 disease, according to an expert at the University of Birmingham and the Cancer Registry of Norway. Called bacteriophages, these viruses are harmless to humans and can be used to target and eliminate specific bacteria.

Obesity linked to higher dementia risk
Obesity is associated with a higher risk of dementia up to 15 years later, finds a new UCL study suggesting that weight management could play a significant role in reducing risk. The findings, published in the International Journal of Epidemiology , suggest that people who are obese in late adulthood face a 31% increased risk of dementia than those whose body mass index (BMI) is within the 'normal' range.

Medicine delivery via microbubbles could be made possible using sound waves
New research has shown that microbubbles, which can be used to deliver drugs to remote parts of the body, can be manipulated by sound waves. Drugs can sometimes be difficult to deliver to specific areas of the body. One way to reach these areas is via microbubbles, which are the subject of intense research for this purpose.

Faulty brain processing of new information underlies psychotic delusions, finds new research
Problems in how the brain recognizes and processes novel information lie at the root of psychosis, researchers from the University of Cambridge and King's College London have found. Their discovery that defective brain signals in patients with psychosis could be altered with medication paves the way for new treatments for the disease.
