Scientists have created a programmable drug system that can zero in on cancer cells with unprecedented accuracy. Built from synthetic DNA, it only activates when it detects a precise combination of tumor markers, preventing damage to healthy tissue. ...

A deadly parasite responsible for sleeping sickness has been found using a surprisingly precise trick to stay hidden in the human bloodstream. Scientists discovered a protein called ESB2 that acts like a "molecular shredder," cutting up specific ...

Colorectal cancer may carry a unique microbial "fingerprint," setting it apart from other cancers and opening a new frontier in diagnosis and treatment. By analyzing DNA from over 9,000 patients, researchers discovered that only colorectal tumors ...

Millions of people start work before sunrise--but their brains aren't ready for it. A new clinical trial has found that the wake-promoting drug solriamfetol can significantly boost alertness in early-morning shift workers struggling with shift work . ...

Cells aren't as passive as scientists once thought--they actively create internal currents to move proteins quickly and efficiently. These "cellular winds" push materials to the front of the cell, enabling faster movement and repair. Discovered by .. ...

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 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 ...
