Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
With new experimental method, researchers probe spin structure in 2D materials for first time（图）
2D材料 自旋结构 “魔角”石墨烯
2023/6/26
By observing spin structure in “magic-angle” graphene, a team of scientists led by Brown University researchers have found a workaround for a long-standing roadblock in the field of two-dimensional el...
How, and for what purpose, are cities and populations tracked, virtualized, and simulated by computational infrastructures in realtime? The semester's second Preston Thomas Memorial Symposium — "Real ...
LHCb begins using unique approach to process collision data in real-time（图）
LHCb 碰撞数据 大型强子对撞机
2023/5/29
Current technology does not allow all Large Hadron Collider (LHC) proton–proton collision data to be stored and analysed. It is therefore necessary to filter out the data according to the scientific g...
The ongoing search for signs of life on Mars relies in part on terrestrial analogs – places on Earth closely resembling the past or current geology and climate of the red planet that can be readily ex...
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the m...
HiLumi News: 7.2-m-long niobium–tin quadrupole magnet manufactured at CERN reaches nominal current for the first time（图）
欧洲核子研究中心 铌锡四极杆磁铁 标称电流
2023/5/26
Another success for the HL-LHC magnet programme: after the successful endurance test of a 4.2-metre-long niobium–tin quadrupole magnet in the United States in spring 2022, the HL-LHC quadrupole’s long...
An app developed by Cornell researchers uses augmented reality to help users repeatedly capture images from the same location with a phone or tablet to make time-lapse videos – without leaving a camer...
NASA’s powerful James Webb Space Telescope opens a new chapter in scientific history, as a large international team – including several Cornell astronomers – found molecular evidence of carbon dioxide...
Astronomers see carbon dioxide on planet outside solar system for first time（图）
詹姆斯韦伯 太空望远镜 系外行星 大气
2023/6/25
Scientists using NASA’s James Webb Space Telescope have captured definitive evidence of carbon dioxide in the atmosphere of a planet beyond our solar system.
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2023/6/9
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena.
Not so with electricity. While an electric c...
Cornell researchers have for the first time successfully imaged the entire depth of the lymph nodes in a living mouse using three-photon microscopy. The breakthrough technique’s micrometer clarity and...
Humans are pretty good at looking at a single two-dimensional image and understanding the full three-dimensional scene that it captures. Artificial intelligence agents are not.
Aheart surgeon doesn’t need to grasp quantum mechanics to perform successful operations. Even chemists don’t always need to know these fundamental principles to study chemical reactions. But the worki...
