These NPs impact the way the silicate glass interacts with light through the now well-known phenomenon called localized surface plasmon resonance.

Researchers observe a hallmark quantum behavior in bouncing droplets

In our everyday classical world, what you see is what you get. A ball is just a ball, and when lobbed through the air, its trajectory is straightforward and clear. But if that ball were shrunk to the size of an atom or smaller, its behavior would shift into a quantum, fuzzy reality. The ball would exist as not just a physical particle but also a wave of possible particle states. And this wave-particle duality can give rise to some weird and sneaky phenomena.

Mouse study successfully regenerates thyroid glands in the spleen

Patients undergoing total thyroidectomy typically require lifelong oral levothyroxine sodium (L-T4) treatment. While effective in maintaining basic serum hormone levels, this treatment falls short in restoring the dynamic, responsive regulatory capacity of triiodothyronine (T3), essential for critical physiologic regulatory functions. Clinical data indicates that T3 deficiency can elevate the risk of hypertension, cardiac dysfunction, and other metabolic or mental health conditions.

Study shows smoking likely leads to brain shrinkage

Smoking likely shrinks the brain, according to a study by researchers at Washington University School of Medicine in St. Louis. The good news is that quitting smoking can prevent further loss of brain tissue—but still, stopping smoking doesn't restore the brain to its original size. Since people's brains naturally lose volume with age, smoking effectively causes the brain to age prematurely, the researchers said.
