Today's discoveries stretch from the subatomic to the planetary. CERN has spotted a decay so rare it took four decades to catch, researchers are finding Alzheimer's clues in unexpected places, and the edge of our Solar System may have one more member than we thought. Let's dive in.

After 40 years, CERN has found evidence of a particle decay that happens roughly once in every 10 billion events. Catching something this rare means sifting through an enormous haystack of ordinary interactions to find the single needle that behaves differently.

Rare decays matter because they are exquisitely sensitive to the rules governing particles. Even a tiny deviation from what theory predicts could hint at physics we have not yet discovered, which is why researchers have chased this one for so long.

Finding evidence of such a vanishingly rare event shows how far detector technology and patience can push the frontier of fundamental physics.

New research suggests Alzheimer's may produce early warning signs outside the brain itself. That is a notable shift, since the disease has traditionally been studied almost entirely through what happens inside the skull.

A separate report points to hidden brain signals that could help predict Alzheimer's years before symptoms appear. Together, the findings point toward a future where earlier detection is possible, giving patients and doctors more time to act.

Spotting Alzheimer's earlier, and from more than one angle, could change how and when the disease is caught.

The Solar System may have a sixth dwarf planet, and it has apparently been hiding in plain sight. If confirmed, it would add another member to a small and fascinating family of worlds beyond the major planets.

It is a reminder that even our own cosmic neighborhood still holds surprises. Objects can sit in existing data for years before someone looks at them in just the right way.

Scientists have discovered a hidden weakness in prostate cancer that could transform how the disease is treated. Identifying a vulnerability like this gives researchers a specific target to aim at rather than relying on broad approaches.

It joins a wave of cancer research this week, including a new approach aimed at eliminating so-called zombie cancer cells that survive chemotherapy, and work uncovering the hidden rules that help brain cancer evade treatment.

Each newly found weakness is a potential opening for therapies that work better against stubborn cancers.

Neutrinos detected in the deep sea are being used to probe whether Einstein's laws of physics hold up. These nearly massless particles travel vast distances and barely interact with matter, which makes them a uniquely clean probe of fundamental rules.

If the laws ever bend, extreme particles like these are among the best places to see it. For now, the deep-sea measurements serve as a demanding stress test of some of the most trusted ideas in physics.

Dinosaurs may have eaten far more fruit than scientists ever thought. The finding challenges the picture of these animals as mostly meat-eaters or leaf-munchers and suggests fruit played a bigger role in their diets.

It is a good example of how new evidence keeps redrawing the ancient food web, one meal at a time.

From the rarest particle decays to the earliest hints of disease, today's science is a reminder that patient curiosity keeps uncovering what was hiding in plain sight. See you next time.
