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

Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, and as components in radio frequency filters and o

Nature has invented countless types of pointy appendages, and scientists have long sought to explain what makes these structures so effective at puncturing other things. A new study models the key physical characteristics of puncturing tools to reflect their diversity in nature,

Advanced magnetic memory and spintronic devices rely on the ability to control magnetic states using electricity. Today, such technologies work by manipulating relatively simple magnetic structures found in ferromagnets, where all the magnetic moments point the same way. However,

An international team led by Juan Diego Soler at the University of Vienna used two of the world's most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest maps ever made of neutral hydrogen in that region of

New research from King's College London published in Public Culture has found that the uneven unfolding of a post-independence law designed to free Indian women from the constraints of Hindu kinship inadvertently created the conditions in which their killings could go publicly un

Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers (220 miles) south of Tokyo, scientists have uncovered inv

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered mater

On Caribbean coral reefs, an unlikely partnership has gone largely unnoticed: Tiny fish regularly nestle within the feathery structures of tube worms. While these sensitive worms typically snap shut at the slightest disturbance, they show a remarkable tolerance for their tiny gue

One of the many marvels of the Roman world is that some of its buildings are still with us. But why have they lasted for so long when some relatively modern structures are in a state of decay after a few decades?
