Newswise — Fish rely on signals from the brain and other organs to balance food intake with their energy needs. One such signal, melanin-concentrating hormone (MCH), was first discovered in salmon and has since been studied across vertebrates. In mammals, MCH generally promotes eating, but studies in fish have produced mixed results: its associated gene appears to respond differently to feeding and fasting in different species. Siberian sturgeon are widely farmed for meat and caviar, yet little was known about their pmch genes, where those genes are active, or how they respond when food becomes available or scarce. A study (DOI: 10.48130/jai-0026-0004) published in Journal of Applied Ichthyology on 30 July 2026 by Zhiqiong Li's & Ni Tang's team, Chengdu Agricultural College, reports two pmch forms whose expression patterns suggest possible roles in appetite regulation and liver energy metabolism. The researchers first isolated and sequenced two pmch transcripts, named pmcha and pmchb, from Siberian sturgeon. Their sequences encode precursor proteins of 179 and 158 amino acids, respectively.

The only thing we can be sure of about the future is that it will be absolutely fantastic. If what I say seems reasonable to you, then I have failed completely, declared Arthur C. Clarke back in 1964 on the BBC. In the legendary BBC Horizon documentaries more than 60 years ago, Clarke made several predictions—including some about the Internet that proved uncannily accurate.

Astronomers led by University of Sydney researchers have detected FRB 20240304B, the most distant fast radio burst ever recorded, which originated when the Universe was only about three billion years old and more than doubles the previous distance record. MeerKAT radio observations combined with James Webb Space Telescope infrared imaging identified the host as a small, metal-poor galaxy undergoing intense star formation, supporting the idea that at least some FRBs come from young magnetars.

Powerful dishes isolate a distant planetary signal A research team led by Kevin N. Ortiz Ceballos analyzed four observing sessions conducted between February 2025 and May 2026. They used the 64-dish MeerKAT radio telescope in South Africa to scan the young Beta Pictoris star system.
