Precessing jet nozzle connecting to a spinning black hole in M87 Scientists have studied the radio galaxy M87, providing insights into the intricate relationship between supermassive black holes and their relativistic jets. M87’s active galactic nucleus (AGN), a compact, energetic region at the galaxy’s core, emits various forms of radiation beyond what stars produce. The…
Seasonal advance of intense tropical cyclones in a warming climate Intense tropical cyclones (TCs) occurring in autumn are shifting earlier in the season, with rates of 3.7 and 3.2 days per decade in the Northern and Southern Hemispheres. This shift is linked to favorable oceanic conditions starting earlier, driven primarily by greenhouse gas forcing. As…
Observation of the effect of gravity on the motion of antimatter Einstein’s general theory of relativity, which describes gravity, has been highly successful in experimental tests. However, concepts like dark matter and dark energy suggest gaps in our understanding of the universe’s gravitational properties. Researchers are exploring gravity in unique settings, including with antimatter. A…
Weather explains the decline and rise of insect biomass over 34 years Insects play a crucial role in ecosystems, but there has been a significant decline in their biomass in Central Europe and other regions. A study reanalyzed 27 years of insect data and found that this decline is strongly influenced by complex weather conditions….
Distinguishing features of Long COVID identified through immune profiling Some people develop post-acute infection syndromes (PAIS) after recovering from viral diseases like COVID-19, resulting in symptoms known as “Long COVID” (LC), including fatigue and cognitive issues. A study involving 273 individuals, some with LC and some without, used immune profiling and machine learning to identify…
