Vacuum birefringence magnetar evidence edges physicists toward Heisenberg’s 90-year-old quantum prediction
The claim is as arresting as it is carefully hedged: observations of a distant magnetar may represent the first direct vacuum birefringence magnetar evidence, potentially confirming a quantum prediction Werner Heisenberg made nearly 90 years ago. The findings, published in Nature, carry the word ‘may’ throughout, and the researchers are the first to say a definitive detection has not yet…

The Science Behind Why Sunglasses Fog Up
Few things are more frustrating than putting on a pair of sunglasses only for the lenses to mist over moments later. Whether you’re walking on a cool morning, cycling up a hill, driving after leaving an air-conditioned building or simply enjoying a warm summer’s day, fogged lenses can quickly become an annoyance. Besides obscuring your view, they can interrupt activities…

Elavon Sage partnership renewal targets UK and Ireland SME payments
The Elavon Sage partnership renewal was announced on 17 August 2026, according to FintechLaunches, with the two companies confirming they will continue jointly delivering payment solutions to small and mid-sized businesses across the United Kingdom and Ireland. The deal extends a long-standing arrangement rather than launching something new, and the claims made for it deserve a closer look. Elavon, the…

Low-fat vegan diet weight loss linked to energy density, not portion cuts
A low-fat vegan diet weight loss effect observed in a 16-week clinical trial had little to do with eating smaller portions and everything to do with the calorie content of each gram of food consumed, according to new research published in JAMA Network Open. The study involved adults with overweight who were assigned either to an ad libitum low-fat vegan…

PANIC study screen time findings challenge eight-year assumptions about children’s cognition
The PANIC study screen time findings, drawn from an eight-year follow-up of children in Finland, point in a direction that cuts against the standard parental worry: children who accumulated more screen time as they grew up tended to show better cognitive processing during adolescence, not worse. The research, published in Pediatric Exercise Science, is associational. Its authors are careful to…

Low-dose digoxin heart failure data span 9,000 patients in new meta-analysis
Three studies centred on low-dose digoxin heart failure treatment, led by cardiologists at Universitair Medisch Centrum Groningen (UMCG), now claim the drug reduces hospital admissions for heart failure by an average of 25%, and the evidence base behind that figure is considerably larger than the individual trial alone. What the UMCG research actually showed The centrepiece trial enrolled 1,000 people…

Blood Bicarbonate CO2 Rise Traced Across 20 Years of US Health Data
A study drawing on more than two decades of US population health data has found that blood bicarbonate CO2 rise trends are tracking atmospheric carbon dioxide concentrations with an unsettling consistency, prompting researchers to call for bicarbonate to be treated as a long-term public health indicator alongside established climate metrics. The research, published in Air Quality, Atmosphere and Health, was…

GIPR brain regions drive weight loss via opposite routes, Cambridge study finds
A mouse study from the University of Cambridge has mapped how GIPR brain regions produce weight loss through two entirely different mechanisms, depending on whether the receptor is activated or blocked. The research, published in Nature Metabolism, offers the clearest explanation yet for a puzzle that has sat at the centre of obesity pharmacology: how can drugs that do opposite…

Blood immune cells enter ageing brain, Stanford study in Nature finds
A Stanford Medicine study published in Nature claims that blood immune cells brain ageing is not the isolated, one-way story textbooks have described. Blood-borne immune cells enter the human brain in substantial numbers as people age, where they appear to transform into microglia, the brain’s own specialised immune cells. If the finding holds up under further scrutiny, it would overturn…

GLP-1 Drugs and the Lateral Septum: A New Target for Addiction Research
GLP-1 lateral septum cravings are at the centre of a growing body of research suggesting that drugs such as Ozempic and Wegovy may do considerably more than suppress appetite: they appear to dampen the brain’s drive to seek out alcohol and other addictive substances, and scientists are beginning to identify the neural mechanism responsible. Writing for The Conversation, Robert Munn,…
