A surprising breakthrough suggests that a drug best known as Viagra could help treat a devastating childhood disease. Researchers found that sildenafil significantly improved symptoms in patients with Leigh syndrome--a rare and often fatal disorder . ...

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining them with DNA folding techniques, scientists are ...

Salt substitutes offer a simple, low-cost way to reduce sodium intake and improve blood pressure, yet very few Americans actually use them--even among those who need them most. A large national analysis spanning nearly two decades found that usage .. ...

Scientists have uncovered a surprising secret about our DNA: it's not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the Salk Institute found that different parts of the . ...

A new shape-shifting material can change both its texture and color in seconds, inspired by the camouflage abilities of octopuses. By precisely controlling how a polymer swells with water, researchers can create detailed, reversible patterns at the . ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough "phonon laser" that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in these systems, researchers can now measure motion . ...

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light's intensity and color. ...

A breakthrough urine test could dramatically speed up how doctors treat urinary tract infections, identifying the right antibiotic in under six hours instead of waiting days. By testing directly from urine--skipping the usual lab culturing step--the ...

Drinking coffee at night might come with an unexpected downside: increased impulsivity. In a new study, fruit flies given caffeine after dark behaved more recklessly, ignoring signals that normally make them stop. Daytime caffeine didn't have the ...

A dramatic surge in kratom-related poison center calls is raising alarm among health experts, as new data shows cases have jumped more than 1,200% over the past decade. Alongside the spike, hospitalizations and deaths linked to the widely available . ...
