Daily briefing: The return of the snail — the month's best science images
NSRI Research Papers1, 1-8 (2026)|
Abstract
The most jaw-dropping science images from February. Plus, whether cancer blood tests actually work and what we lose when we can't see the stars.
Welcome to the daily briefing. Today we are looking at the most spectacular science images captured over the past month, ranging from microscopic wonders to vast cosmic phenomena.
The Return of the Snail
Our featured image this month is a stunning macro photograph of a newly discovered species of deep-sea snail, found near hydrothermal vents in the Mariana Trench. Its shell, coated in iron sulfide, gives it a metallic, almost robotic appearance.
Cancer Blood Tests: A Reality Check
We also delve into the latest research on multi-cancer early detection (MCED) blood tests. While promising, a new meta-analysis suggests that their clinical utility may be overstated, with high rates of false positives leading to unnecessary anxiety and invasive follow-up procedures.
Losing the Night Sky
Finally, we explore the growing problem of light pollution and satellite mega-constellations. Astronomers warn that we are rapidly losing our view of the stars, which not only impacts scientific observation but also severs a fundamental human connection to the cosmos.
