Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become active again at the wrong time. Now, two studies published

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, molecular chemistry and elemental composition across eve

Northwestern Medicine scientists have identified a novel mechanism used by the bacteria responsible for gonorrhea to evade immune detection and achieve widespread infection, according to a recent study published in the Proceedings of the National Academy of Sciences. Neisseria go

The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene circuit' platform that can simultaneously read multiple

Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes called stoppers, are added to the ends of the axle.

Water-saving irrigation practices, including intermittent irrigation, are essential for sustainable rice cultivation amid growing freshwater shortages. However, periodic drainage creates aerobic soil conditions that drastically boost cadmium (Cd) bioavailability, leading to sever

Cells are crowded, dynamic places where thousands of molecules interact in tight quarters. Until now, scientists lacked a reliable way to see many of these molecular interactions as they happen. Researchers at the University of Illinois Chicago have now developed a new imaging me

Trabalho aponta que, apenas 24 horas após o contato com níveis de radiação comparáveis aos encontrados no espaço profundo, já é possível identificar mudanças genéticas no órgão O post Estudo sugere que viagens espaciais aceleram envelhecimento do fígado apareceu primeiro em Olhar Digital.

Enquanto as seleções se preparam para um duelo histórico no gramado, as culinárias francesa e espanhola travam sua própria batalha de sabores — e os dois lados têm argumentos de sobra para reivindicar o título.

Ingredientes presentes em protetores solares, cremes de recuperação e produtos antiatrito usados por corredores estão sob nova análise científica. Entenda o que muda para você.
