The thermometer reads 95°F (35°C) in Brooklyn, and vulnerable individuals need information to take appropriate action. New York City officials must gather facts quickly to provide updates on cooling centers, power outages and other details that could save lives. Are these details

Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly adapt to changes in their environment.

Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously difficult to study because they rapidly transform

Animals may inhabit the same world as us, but new research shows how their perceptions of what is around them differsImagine standing in your garden. A bumblebee whizzes overhead too quickly to follow, a sparrow darts from the fence to the trees, and a snail lugs itself across th

Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light to be useful for these purposes, engineers need to be

Some World Cup crowds are more in sync than others, but all have some common features, Northeastern experts say. O recorte ajuda a contextualizar a pauta dentro de Agro.

Caddisflies are among nature's master underwater builders, capable of spinning sticky silk that they use to form protective cases and webs in freshwater streams. Scientists like the University of Utah's Russell Stewart have long studied this bioadhesive material in the hope of us

If a liquid is cooled slowly to its freezing point, it becomes a crystal in which the constituent particles are arranged in an ordered pattern. In contrast, when the liquid is cooled very quickly, the particles are unable to arrange themselves in an ordered fashion, and it become

Astronomers have uncovered 31 of the oldest known quasars, including the two earliest ever detected, shining from a time when the universe was only about 670 million years old. Powered by supermassive black holes billions of times the Sun’s mass, these incredibly bright objects c

In drug discovery, building complex molecules quickly is the name of the game. O recorte ajuda a contextualizar a pauta dentro de Agro.

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution

In the UK, these scams have become an epidemic, rising 147% between January and March, compared with the same time last year. Why are they suddenly so common? And what can you do if you’re charged thousands for a quick, easy job?Sarah was alone in her flat with her three-month-old baby when a man put a card machine in her face and demanded she pay £2,209. A few hours earlier Sarah, 30, had been for a walk with her daughter when it dawned on her that she had left her keys at home. She d
