Lonely people incur an extra £850 in annual healthcare costs to the NHS, as well as experiencing worse mental and physical health In the UK, 4 in 10 citizens identify as being lonely at least some of the time, and people who report being often lonely incur about £850 more in annual National Health Service costs than their non-lonely counterparts, according to a study published September 3, 2025 in the open-access journal PLOS One by Nia Morrish from the University of Exeter, and colleagues.  The World Health Organization recognizes loneliness ...

From corn chips to tofu, climate change is messing with the menu. A new global study led by the University of British Columbia shows that hotter and drier conditions are making food production more volatile, with crop yields swinging more sharply from year to year. For some, it may mean pricier burgers; for others, it can bring financial strain and hunger. Published today in Science Advances, the study is the first to show at a global scale how climate change is affecting yield swings of three of the world’s most important food crops: corn, soybean and sorghum. For every degree of warming, year-to-year ...

Individuals with an increased risk for dementia due to Alzheimer’s disease can have impaired spatial orientation skills. DZNE researchers come to this conclusion based on a study involving around 100 older adults who were tasked with determining their position within a virtual environment. In this, participants with “subjective cognitive decline” (SCD) – a risk factor for Alzheimer’s disease – performed worse than members of the control group. In contrast, there were no significant differences ...

First study to investigate how apple juice changes saliva’s lubricating properties using advanced techniques While apple juice temporarily disrupts the mouth's natural protective coating, the effects begin to wear off within 10 minutes Research challenges assumptions about fruit juice being immediately harmful to oral health, which could inform new hygiene routines  Peer-reviewed, data-analysis and experimental study, people  A new study led by the University of Portsmouth suggests our saliva is stronger than we thought.  The research, published in PLOS One, is the first to examine how drinking apple juice affects saliva’s lubricating ...

A new study, led by experts at the University of Nottingham, has found that vegan diets for dogs sold in the UK provide similar nutrition to meat-based diets. The study, led by Rebecca Brociek from the School of Veterinary Medicine and Science, and published in PLOS One, highlights the importance of a balanced and nutritional diet for our canine companions. Dogs, like humans, are omnivores and require specific nutrients rather than specific ingredients. As plant-based diets gain popularity in human nutrition, the pet food industry is following suit with vegan diets becoming ...

(Auburn, AL) Imagine a child with eczema who scratches a patch of irritated skin. A tiny opening forms, invisible to the eye. Into that breach slips a common bacterium, Staphylococcus aureus. For many people, the bacteria would remain harmless. But in someone with a weakened skin barrier, the microbe can cling tightly, multiply, and trigger an infection that is difficult to control. In severe cases, staph spreads beyond the skin and becomes life-threatening. Resistant strains such as MRSA turn what should be a treatable infection into a medical nightmare, one that claims tens of thousands of lives each year in the United States alone. The question that has puzzled ...

A new study reveals the profound emotional and physical toll of extreme morning sickness, with more than half of affected women reporting they considered terminating their pregnancy, and 9 in 10 saying they had thought about not having more children. The national survey, published in PLOS ONE, is one of the most comprehensive investigations into the lived experience of hyperemesis gravidarum (HG)—a severe form of nausea and vomiting in pregnancy – in Australia. It highlights not only ...

Colorectal cancer is unique in having its own microbial ‘fingerprint’ – according to new research from the University of East Anglia. Colorectal cancer is the fourth most common cancer in the UK and the second deadliest. The research could help doctors better understand how this cancer develops, how aggressive it might be, and even how a patient might respond to treatment. The team studied whole genome sequencing (WGS) data from more than 9,000 cancer patients.   The analysis, published today, also challenges scientific claims that all cancers are associated with a ...
