Changes in rock formations from before and after the mass extinction event 66 million years ago may reflect how dinosaurs acted as ecosystem engineers, shaping vegetation and even the meandering of rivers Changes in rock formations from before and after the mass extinction event 66 million years ago may reflect how dinosaurs acted as ecosystem …

Dry eyes are far more common than previously believed, with over half of adults in the US and Europe experiencing symptoms, yet most remain undiagnosed for years. The large-scale NESTS study reveals that sufferers often endure daily discomfort that disrupts work, driving, and even surgery outcomes. Many accept the condition as part of aging, unaware …

What we eat as we age may determine how many chronic illnesses we face later in life. A 15-year study of more than 2,400 older adults reveals that diets rich in vegetables, whole grains, nuts, and healthy fats slow the accumulation of diseases like cardiovascular problems and dementia—while inflammatory diets heavy in red meat and …

Trial participants who received an increased weekly dose of Wegovy lost 19 per cent of their body weight in a year on average, but also saw a higher risk of painful skin sensations and nausea Trial participants who received an increased weekly dose of Wegovy lost 19 per cent of their body weight in a …
Higher dose of Wegovy ups both weight loss and side effects Read More »
Scientists discovered that certain blood proteins linked to brain injury and inflammation strongly correlate with early signs of memory and cognitive decline, especially in Hispanic and Latino adults. This breakthrough points to a future where Alzheimer’s could be detected early with a simple blood test. Scientists discovered that certain blood proteins linked to brain injury …

New research from Denmark challenges long-held assumptions about body weight and health, revealing that being overweight—or even moderately obese—does not necessarily increase the risk of death compared to those at the upper end of the “normal” BMI range. In fact, those who are underweight or at the lower end of the so-called healthy spectrum faced …

Plants are spreading across the globe faster than ever, largely due to human activity, and new research shows that the very same traits that make plants thrive in their native lands also drive their success abroad. A study of nearly 4,000 European species reveals that tall, adaptable, nutrient-loving generalists dominate both at home and in …
Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive only within a narrow temperature range, and warming oceans could slash their populations by up to 50% …

New research has revealed that East Antarctica’s vast and icy interior is heating up faster than its coasts, fueled by warm air carried from the Southern Indian Ocean. Using 30 years of weather station data, scientists uncovered a hidden climate driver that current models fail to capture, suggesting the world’s largest ice reservoir may be …
Antarctica’s frozen heart is warming fast, and models missed it Read More »
Scientists at Stanford have found that hyperactivity in the brain’s reticular thalamic nucleus may drive autism-like behaviors. In mouse models, drugs and neuromodulation techniques that suppressed this overactive region reversed symptoms, hinting at new therapeutic pathways that overlap with epilepsy treatments.
