Dark energy revived Einstein’s discarded cosmological constant and reshaped the leading model of the universe. In 1917, Albert Einstein had recently completed his general theory of relativity, the framework that transformed how physics understands gravity. He soon applied those equations to a much larger question: how the universe changes over time. Gravity was the natural […]

The Universe Can Expand Faster Than Light Without Breaking Physics
The universe’s expansion makes cosmic distance far less intuitive than simply measuring how long light has traveled. An expanding universe makes distance harder to define because space keeps growing while light is in transit. Objects continue to emit light, but as that light travels toward us, the average separation between galaxies increases (yes, I know […]
Healthier Eating Could Trigger a $630 Billion Farming Shake-Up
A worldwide move toward healthier diets, more efficient farming, and less food waste could dramatically reorganize global agriculture by 2050. Following global recommendations to adopt healthier diets, make farms more productive, and cut food waste in half could dramatically alter agriculture by 2050. According to new modeling, these changes could reduce the amount of land […]

A Hidden Protein-Folding Failure May Help Drive Diabetes
A study offers new insight into how insulin-producing cells could become more resilient to stress as diabetes progresses. Before proteins can work inside a cell, they must twist and fold into precise three-dimensional forms. As prediabetes advances toward diabetes, that careful process can break down, allowing defective proteins to accumulate and place insulin-producing cells under […]
The Exercise Paradox: Why Workouts Don’t Guarantee Weight Loss
Exercise may not drive major weight loss, but it can help maintain results and improve health. Burning more calories than you consume should lead to weight loss, at least in theory. In everyday life, however, the body often makes that calculation far more complicated. Many people combine smaller portions or calorie tracking with regular exercise […]
Why AI May Never Reach Human Intelligence
A new analysis argues that AI may never truly think like humans because the most important parts of human intelligence cannot be programmed into machines. A prominent computer scientist argues that a proposal made by Alan Turing, widely regarded as the father of theoretical computer science, sent artificial intelligence research in the wrong direction for […]
