Solar sails may encounter drag from light itself as they approach a significant fraction of the speed. Getting a spacecraft to another star is not simply a matter of building a bigger rocket. Chemical propulsion is far too slow for interstellar travel on practical timescales, which is why many mission concepts turn to light itself […]
The Strange Force That Could Slow Interstellar Solar Sails
Solar sails may encounter drag from light itself as they approach a significant fraction of the speed. Getting a spacecraft to another star is not simply a matter of building a bigger rocket. Chemical propulsion is far too slow for interstellar travel on practical timescales, which is why many mission concepts turn to light itself […]
Beyond Heisenberg: Scientists Discover a New “Space-Time Limit” in Quantum Physics
Scientists have uncovered a hidden quantum limit that prevents an electron’s position and timing from ever being known with perfect precision. Quantum physics sets hard limits on what can be known about a particle. Werner Heisenberg’s uncertainty principle famously states that position and momentum cannot both be measured with unlimited precision. The problem is not […]
New Technique Exposes Hidden Multiple Sclerosis Damage in Routine MRI Scans
Researchers have developed an artificial intelligence method that can uncover previously hidden signs of multiple sclerosis in routine MRI scans. For decades, multiple sclerosis specialists have been forced to study the disease through an incomplete picture. Standard magnetic resonance imaging (MRI) can reveal damage in the brain’s white matter, but some of the lesions most […]

Intermittent Fasting Benefits May Last Long After the Diet Ends
An eight-hour eating window helped adults maintain weight loss one year after a 12-week intervention. For many people trying to lose weight, the hardest part begins after the diet ends. The scale may move during a structured program, but keeping that weight off months later is often the real test. Research from the University of […]
The Richest 10% Cause up to $5.7 Trillion in Environmental Damage Each Year
A new study finds that biodiversity loss accounts for the largest share of global environmental damage, surpassing climate change. A relatively small share of the world’s population may be causing environmental damage on the same financial scale as the global effort needed to repair it. According to a new study, the highest-consuming 10% of people […]
