Sky’s the limit for cloud-inspired method of guiding light
Scientists have taken inspiration from the way sunlight passes through clouds to discover an entirely new way of controlling and guiding light. The breakthrough research, led by physicists from the University of Glasgow, allows light waves to be guided around curved paths tunnelled through opaque materials which would normally scatter them in all directions.

Education, occupation, and wealth affect the risk of cognitive impairment
Socioeconomic factors such as education, occupation, and wealth influence the likelihood of developing cognitive impairment or dementia in later life and whether a person is likely to recover, finds a new study led by UCL researchers. The research, published in Scientific Reports , followed 8,442 adults aged 50 and above in England over 10 years from 2008/09 to 2018/19, to examine how socioeconomic factors at the start of the study were associated with changes in cognitive status.

Using Mathematics to Better Understand Cause and Effect
Cause and effect. We understand this concept from an early age. Tug on a pull toy's string, and the toy follows. Naturally, things get much more complicated as a system grows, as the number of variables increases, and as noise enters the picture. Eventually, it can become almost impossible to tell whether a variable is causing an effect or is simply correlated or associated with it.

New development could help deliver improved potassium-ion batteries
A breakthrough in material science could help deliver a new generation of affordable batteries, scientists say. An international team of researchers led by chemists from the University of Glasgow and battery testing experts at Helmholtz Institute Ulm have implemented a material made from chromium and selenium in a potassium-ion battery.

Revealing causal links in complex systems
MIT engineers' algorithm may have wide impact, from forecasting climate to projecting population growth to designing efficient aircraft. Getting to the heart of causality is central to understanding the world around us. What causes one variable - be it a biological species, a voting region, a company stock, or a local climate - to shift from one state to another can inform how we might shape that variable in the future.

A step toward clinically useful brain-behavior machine learning models
Many predictive models don't work well across different settings and populations. But testing them on diverse data can help, Yale researchers show. Relating brain activity to behavior is an ongoing aim of neuroimaging research as it would help scientists understand how the brain begets behavior - and perhaps open new opportunities for personalized treatment of mental health and neurological conditions.

Political pros no better than public in predicting which messages persuade
A new study by Yale political scientist Josh Kalla shows that experts performed little better than chance in identifying effective political messaging. Political campaigns spend big bucks hiring consultants to craft persuasive messaging, but a new study coauthored by Yale political scientist Joshua L. Kalla demonstrates that political professionals perform no better than laypeople in predicting which messages will sway voters.

Glaucoma drug shows promise against neurodegenerative diseases, animal studies suggest
A drug commonly used to treat glaucoma has been shown in zebrafish and mice to protect against the build-up in the brain of the protein tau, which causes various forms of dementia and is implicated in Alzheimer's disease.

Unraveling the Link Between Hepatitis and Kidney Damage
The hepatitis E virus affects the liver. But infected liver cells secrete a viral protein that reacts with antibodies in the blood and may form complexes that can damage the filter structure of the kidneys, as researchers from the University of Zurich and the University Hospital Zurich have proven for the first time.

Scientists engineer ’glowing’ gel to improve eye surgery
Innovation tackles long-standing challenge in cataract procedures by making surgical materials visible under blue light Cataracts-a condition that causes clouding of the eye's lens and deteriorating vision-will affect nearly everyone who lives long enough. Now Johns Hopkins scientists have pioneered a new color-changing hydrogel that could reduce complications from cataract surgery, one of the world's most commonly performed procedures.

Nurses: key professionals in the care of rare diseases
A team of researchers from the Autonomous University of Madrid (UAM) and the Puerta de Hierro University Hospital has proposed a map of competencies to optimize the care of patients with rare diseases, a group that faces a great lack of treatment and inequalities in care.

Why Lake Geneva emits large quantities of CO2
Unlike oceans, lakes are major emitters of CO2. Why is this so, and what mechanisms are at work? Scientists at the University of Lausanne have succeeded in explaining the complete carbon cycle in Lake Geneva for the first time, generating a model that can be applied to several of the world's great lakes.

A rudimentary quantum network link between Dutch cities
An international research team led by QuTech has demonstrated a network connection between quantum processors over metropolitan distances. Their result marks a key advance from early research networks in the lab towards a future quantum internet. The team developed fully independently operating nodes and integrated these with deployed optical internet fibre, enabling a 25 km quantum link.

Neurotechnology boosts memory without surgery
Researchers have combined virtual reality, non-invasive brain stimulation and advanced brain imaging techniques to improve spatial navigation in healthy participants. The study is a first step in addressing dementia in an aging population without medication or surgery. As we age, it becomes more difficult to remember where things are-whether it's recalling where we left the keys or where we parked the car.

Fundamental quantum model recreated from nanographenes
Quantum technologies exploit the unusual properties of the most fundamental building blocks of matter. They promise breakthroughs in communication, computing, sensors and much more. However, quantum states are fragile, and their effects are difficult to grasp, making research into real-world applications challenging.

How ’stressed’ potatoes become climate fit
Research network investigates how future potato varieties can be adapted to climate change Heat, drought and flooding - nature is under stress, and so is the potato. As a staple food, there is a particular interest in making potatoes climate-ready. An international team led by the University of Vienna and with the participation of the University of Bonn has now investigated how this can be achieved in the four-year EU project ADAPT.

Low-sugar diet in early childhood reduces lifetime risk of chronic disease
Historical data linked to end of sugar rationing in the United Kingdom offers unique glimpse into diet and health A low-sugar diet in the first years of life can significantly reduce the risk of chronic diseases in adulthood, a study based on historical data has found. The researchers pulled data from UK Biobank, focusing on adults conceived just before and after the 1953 end of wartime sugar rationing in the United Kingdom.

Long COVID inflammation damages the heart
University of Queensland-led research has found inflammatory markers in the blood of long COVID patients which could explain why many experience ongoing cardiovascular issues. Associate Professor Kirsty Short said the team set out to investigate the cause of persistent chest pain and heart palpitations commonly reported by many long COVID sufferers.

Text message reminders help teens brush their teeth
Text message reminders can help to improve tooth brushing habits in teenagers, particularly those from low-income families, a new study has shown. Researchers from Cardiff University and the Universities of Sheffield, Leeds, York and Dundee, have collaborated to investigate the effectiveness of a new programme designed to encourage better brushing habits and reduce tooth decay in secondary school pupils.
