1. What you eat could decide the planet’s future

   What we put on our plates may matter more for the climate than we realize. Researchers found that most people, especially in wealthy countries, are exceeding a “food emissions budget” needed to keep global warming below 2°C. Beef alone accounts for nearly half of food-related emissions in Canada. Small changes—less waste, smaller portions, and fewer steaks—could add up to a big climate win.

2. Scientists reverse Alzheimer’s in mice and restore memory

   Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimer’s biomarkers. The results offer fresh hope that recovery may be possible.

3. Why consciousness can’t be reduced to code

   The familiar fight between “mind as software” and “mind as biology” may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, computation is inseparable from the brain’s physical structure, energy constraints, and continuous dynamics. That reframes consciousness as something that emerges from a special kind of computing matter, not from running the right program.

4. AI supercharges scientific output while quality slips

   AI writing tools are supercharging scientific productivity, with researchers posting up to 50% more papers after adopting them. The biggest beneficiaries are scientists who don’t speak English as a first language, potentially shifting global centers of research power. But there’s a downside: many AI-polished papers fail to deliver real scientific value. This growing gap between slick writing and meaningful results is complicating peer review, funding decisions, and research oversight.

5. We are living in a golden age of species discovery

   The search for life on Earth is speeding up, not slowing down. Scientists are now identifying more than 16,000 new species each year, revealing far more biodiversity than expected across animals, plants, fungi, and beyond. Many species remain undiscovered, especially insects and microbes, and future advances could unlock millions more. Each new find also opens doors to conservation and medical breakthroughs.
