Eggs don’t raise ‘bad’ cholesterol, saturated fat does

New research from the University of South Australia and published in The American Journal of Clinical Nutrition clears eggs of their long-standing bad rap, showing that eating two eggs a day in a low saturated fat diet doesn’t raise LDL cholesterol. Instead, it’s saturated fat — not dietary cholesterol — that drives heart risk. The findings challenge decades of dietary advice and suggest your eggs are fine — you might want to watch the bacon, though.

New MRI scanner maps the brain in microscopic detail

Scientists funded by the National Institutes of Health (NIH) have unveiled a next-gen MRI system, called the Connectome 2.0, that noninvasively images brain structures at near-cellular resolution — revealing tiny nerve fibers previously visible only in animal or postmortem studies. The breakthrough could change the way researchers study brain circuits disrupted in neurological and psychiatric disorders and marks a major step toward building a complete wiring diagram of the human brain.

FDA moves to scrap 52 outdated food standards

The Food and Drug Administration (FDA) announced plans to revoke 52 obsolete food standards — covering products from canned fruit to macaroni — in a move aligned with the Trump administration’s push to cut red tape. Officials say many of the decades-old “recipe rules” no longer protect consumers and may stifle innovation. The effort is part of a broader deregulatory review of over 250 food Standards of Identity (SOI) to ensure they are useful, relevant and serve consumers, according to the FDA.
