A major U.S. study showed people eating around nine servings of ultra-processed foods daily had higher risk of heart attack, stroke or heart disease death compared to those eating about one serving. Each additional daily serving raised the likelihood by more than 5 percent after adjusting for calories, diet quality and health conditions.

Researchers found belly fat was more strongly linked to heart failure risk than overall BMI, even among people with normal weight, with inflammation appearing to drive the harm. Waist measurement could provide a simpler early warning for this hidden risk.

Research documented H5N1 highly pathogenic avian influenza spreading through marine mammals, with over 50,000 seals and sea lions affected along South America's coast since the virus's emergence in 1996. The pathogen has now reached every continent except Oceania.

UBC researchers found invasive fire-prone grasses rapidly colonize burned landscapes in interior British Columbia, with native recovery slower than expected even two years post-fire. This creates extended vulnerability in large areas of burn scars.

Milkweed has modified its toxins by adding a nitrogen-sulfur structural element that bypasses monarch butterflies' resistance mechanisms. The finding highlights an evolutionary strategy of structural innovation beyond simply increasing toxin levels.

Photopharmacology researchers developed a beta blocker that can be activated or deactivated by specific light wavelengths, allowing targeted effects in one body area while remaining inactive elsewhere. This approach aims to limit side effects of medications like blood pressure treatments.

NUS Medicine researchers created an AI-guided method to enhance base editors, making these compact gene-editing tools more precise and potentially safer for future therapies. The advance targets smaller, accurate DNA corrections.

Planetterrian Spotlight
Ravens in Yellowstone navigate directly to likely wolf kill sites using memorized landscape patterns rather than following the predators. The tracking study shows these birds operate with a sophisticated mental map of where food is likely to appear, sometimes traveling long distances with purpose. This challenges the simpler "follow the wolves" assumption that had persisted and underscores the cognitive sophistication of corvids. It could shift how we understand animal intelligence and foraging strategies in complex ecosystems. What similar hidden capabilities might other species have that we’ve misinterpreted?
Science Deep Dive: How belly fat harms the heart differently than other fat
Most people assume that carrying extra weight is risky mainly because of the total number on the scale or overall BMI. In reality, the location of that fat matters far more than many realize, especially when it accumulates around the waist. Right now, as you sit or stand listening, visceral fat around your organs is biologically active tissue that releases inflammatory molecules into your bloodstream. Those signals can reach the heart muscle and promote harmful remodeling even if your weight falls in the normal range. A key detail that changes how we think about risk is that this connection to heart failure appears stronger than the link from BMI alone. The next time you measure health progress, checking your waist circumference alongside weight gives a clearer picture of what’s happening inside. This knowledge points to a practical step: paying attention to abdominal fat through simple tape measurements or consistent movement patterns can help spot risks earlier than waiting for the scale to shift dramatically.
Today's edition pulls together discoveries that quietly reshape what we thought we knew about intelligence in nature, hidden heart risks, and tools that could make treatments more precise.
