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...
A rare and persistent rapid-fire fast radio burst source – sending out an occasional and informative cosmic ping from more than 3.5 billion light years away – now helps to reveal the secrets of the br...
Identification of the Arabidopsis calmodulin-dependent NAD+ kinase that sustains the elicitor-induced oxidative burst
NAD+kinase Calmodulin Calcium NADP+42 zeta toxin flagellin22 Arabidopsis thaliana
2024/2/27
NADP(H) is an essential cofactor of multiple metabolic processes in all living organisms, and in plants, NADP(H) is required as the substrate of Ca2+-dependent NADPH oxidases, which catalyze a reactiv...
Ancient molecules from the sea likely burst into the air from ocean waves（图）
Ancient molecules sea air ocean waves carbon cycle organic matter
2019/11/5
When waves break in the ocean, they inject tiny particles into the air, called aerosols, that carry organic molecules more than 5,000 years old. The discovery, published in Science Advances by Steven ...

Why Do Starburst Galaxies 'Burst'? ALMA Sees Super Stellar Nurseries at Heart of Sculptor Galaxy
Starburst Galaxies Burst Super Stellar Nurseries Heart of Sculptor Galaxy
2015/3/4
Starburst galaxies transmute gas into new stars at a dizzying pace – up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while others...
