A team of biologists from the University of Münster has investigated whether and how the immune system can influence the behaviour of sticklebacks It's a well-known fact that if you don't get enough sleep, you're more likely to get sick. And it has also been observed that people sleep differently when they're infected.

Findings build on growing evidence that adding flavours to vaping solutions can increase the dangers. Berry-flavoured vapes can weaken the lungs' natural defences, making it harder for the body to fight off infections, new research suggests. The study compared effects of flavoured e-cigarettes to those of unflavoured ones.

University of Wisconsin-Madison researchers are warning that artificial intelligence tools gaining popularity in the fields of genetics and medicine can lead to flawed conclusions about the connection between genes and physical characteristics, including risk factors for diseases like diabetes. The faulty predictions are linked to researchers' use of AI to assist genome-wide association studies.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

Study: Amyloid Accelerator Polyphosphate Implicated as the Mystery Density in α-Synuclein Fibrils (DOI: 10.1371/journal.pbio. Research led by the University of Michigan has provided compelling evidence that could solve a fundamental mystery in the makeup of fibrils that play a role in Alzheimer's, Parkinson's and other neurodegenerative diseases.

Unsplash Teams from the departments of clinical and biological hematology, obstetrics and gynecology, pharmacovigilance, medical intensive care, infectiology, as well as the clinical research unit of theHôpital Cochin-Port Royal AP-HP, Université Paris Cité, Inserm and the HEMAPREG network, coordinated by Mr Pierre Pinson and Drs Ismael Boussaid and Rudy Birsen, have conducted a study on pregnancy-associated hematological cancers.

In a recent study, an international research team with significant involvement from MedUni Vienna has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics. The study showed that the plastic particles not only impair the effect of the drugs, but could also promote the development of antibiotic-resistant bacteria.

Ida Anna Cappello, a researcher at the Heart Rhythm Management Center at the University Hospital Brussels (VUB), developed biomedical technology with patient-specific, 3D printed surgical templates for cardiovascular procedures. Working closely with cardiologists and cardiac surgeons, Cappello's work holds great promise for significantly improving precision in complex cardiac surgeries.

First-of-its-kind Canadian study found 10 Ontario children died of an opioid-related cause between 2017 and 2021 A new study from Western researchers in collaboration with the Office of the Chief Coroner of Ontario highlights the scope of opioid-related deaths in young children in Ontario, while providing a clearer picture of the risk factors.

Some sick Black patients are likely labeled as "healthy- in AI datasets due to inequitable medical testing Black patients are less likely than white patients to receive medical tests that doctors use to diagnose severe disease, such as sepsis, researchers at the University of Michigan have shown. Because of the bias, some sick Black patients are assumed to be healthy in data used to train AI, and the resulting models likely underestimate illness in Black patients.

Researchers from Bonn uncover how tiny eye movements and the density of our photoreceptors aid in sharp vision Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details.
