New mutation hotspot discovered in human genome
Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease. The regions are located at the starting point of genes, also known as…

Scientists identify five structural eras of the human brain over a lifetime
Neuroscientists have identified five "major epochs" of brain structure over the course of a human life, as our brains rewire to support different ways of thinking while we grow, mature, and ultimately decline.A study by researchers compared the brains of 3,802 people between 0 and 90 years old…

How much CO₂ does your flight really produce? How to know if carbon footprint claims are accurate
When two people book the same flight, they can get wildly different carbon footprints from online calculators. Many carbon calculators leave out big chunks of climate impact or rely on oversimplified assumptions.Here's what's missing, why it matters and a practical checklist you can use to judge…

Humans are evolved for nature, not cities, say anthropologists
This mismatch is creating lots of problems for us and we need to change our thinking and behaviour.A new paper by evolutionary anthropologists argues that modern life has outpaced human evolution. The study suggests that chronic stress and many modern health issues are the result of an evolutionary…
