Scientists prove long-standing wave amplification theory

Equipment used in the Zel’dovich experiment. Credit: University of Southampton Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing “twisted waves”—those with angular momentum—off of an object which is rotating in … Read more

New Mo carbide catalysts show high stability and activity in CO₂ conversion

Abstract image. Credit: DICP Molybdenum (Mo) carbides, known for their unique electronic and structural properties, are considered promising alternatives to noble metal catalysts in heterogeneous catalysis. However, traditional methods for preparing Mo carbides suffer from complex processes, stringent synthesis conditions, challenging crystal regulation, and high energy consumption. Additionally, Mo carbides are susceptible to oxidation and … Read more

How context-specific factors control gene activity

Credit: Pixabay/CC0 Public Domain Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned on and off to meet the cell’s demands. But … Read more

Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots

Supermassive black holes grow by pulling in matter around them. Credit: M. Kornmesser/ESO Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA’s most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can impersonate other marine animals to avoid … Read more
