Two-step fermentation removes up to 99% of odors in plant proteins
Off-putting smells can make even the healthiest of foods unpalatable. In a new study, researchers have developed a way to remove unpleasant aromas from plant-based proteins to make them smell more appealing. They did so by designing a two-step fermentation process to counter
AI captures particle accelerator behavior to optimize machine performance

Omega-3 fish oil supplements could backfire without this key enzyme
Fish oil’s cancer-fighting reputation may hinge on a little-known gene. Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially DHA. The
Can our pets really say 'I love you'? Science is finding out
Purrs of contentment. Soulful eyes locked on yours over dinner. Valentine's Day? Not for pet owners. For those of us who share our lives with animals, this is a daily—if not exactly romantic—experience. So are the various barks, meows, whines, and other, sometimes adorable,
The shape of skis makes the biggest difference in maneuverability
