Sombrero Galaxy dazzles in new Webb images and video
A new mid-infrared image from the NASA/ESA/CSA James Webb Space Telescope features the Sombrero galaxy, also known as Messier 104 (M104). The signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is reve.....»»
Brighter and more efficient LEDs with low polarization resist "efficiency droop"
Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, they become less efficient......»»
Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission......»»
