At the time of the Big Bang, 13.8 billion years ago, every particle of matter is thought to have been produced together with an antimatter equivalent of opposite electrical charge. But in the present-...
New research from a multidisciplinary team helps to illuminate the mechanisms behind circadian rhythms, offering new hope for dealing with jet lag, insomnia and other sleep disorders.
New blue light technique could enable advances in understanding nanoscale technologies（图）

A team of Brown University researchers created a solution to a nanoscale resolution challenge that has for decades limited the study of materials that could lead to more energy efficient semiconductor...
To save caterpillars, turn off your porch light.
The way electrons interact with photons of light is a key part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently a weak one because of a major mismatc...
Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific...
In a scene from “Star Wars: Episode IV — A New Hope,” R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help. That scene, filmed more than 45 years ago, involved ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Eccentricity sheds light on gravitational-wave dark sirens in the mid-band
偏心率 中频带 引力波 暗警报器

The source localization and distance inference of gravitational waves (GWs) are two crucial factors for GW standard sirens as precise probes of cosmology, astrophysics, and fundamental physics. In thi...
What a long, strange trip it’s been for psychedelic drugs. From their use in ancient indigenous ceremonies, to their often-caricatured association with the 1960s counterculture, to their recent reemer...
Ask a smart home device for the weather forecast, and it takes several seconds for the device to respond. One reason this latency occurs is because connected devices don’t have enough memory or power ...
Why do woodpeckers peck? New discovery about bird brains sheds light on intriguing question（图）
鸟类大脑 交际鼓声 动物行为学

A team led by a Brown biologist discovered that the same specialized brain area that helps songbirds learn their songs also exists in woodpeckers, suggesting that the communicative drumming evolved in...
Cramming multiple pairs of shoes into a vacation suitcase, twisting and flipping them into different arrangements to fit every pair needed, is a familiar optimization problem faced by harried traveler...
Chemical reactions that are driven by light offer a powerful tool for chemists who are designing new ways to manufacture pharmaceuticals and other useful compounds. Harnessing this light energy requir...
Through his close relationship with the woods of Walden Pond in Concord, Massachusetts, Henry David Thoreau observed the ebb and flow of the natural world first-hand. Prolific in his practice of colle...
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors....
