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 . ...

A new study suggests that simplifying your diet by eating the same meals and keeping your calorie intake consistent could help you lose more weight. Researchers found that people who followed predictable eating routines during a 12-week program lost ...
