            "title": "Evidence for global-scale magnetically modified Rossby waves in the Sun",
            "description": "Understanding and predicting solar magnetism is critical for safeguarding satellites, planning space missions and mitigating the effects of space weather on modern infrastructure. However, the physical processes governing the solar cycle remain elusive. Here, applying methods of helioseismology on observations taken by the Helioseismic and Magnetic Imager, we report the possible detection of global magnetized inertial dispersions, a slow mode and a weaker, retrograde feature possibly consistent with the fast mode, whose dynamics are theorized to modulate the solar dynamo. These modes appear to be confined to layers r/R⊙ ≲ 0.98, exhibit amplitudes weaker than those of hydrodynamic Rossby waves and resonate at frequencies consistent with the presence of an effective large-scale toroidal magnetic field of strength $$\\sim 5\\sqrt{\\rho /{\\rho }_{{\\rm{S}}}}$$ Gauss, where ρ is density and ρS ≈ 4 × 10−7g cm−3 is the surface density. If the toroidal field were to be located at the base of the convection zone (ρ ≈ 0.44 g cm−3), its amplitude would be ~5 × 103 G, consistent with helioseismic and other estimates. By mapping these motions in the surface layers, we uncover a window into the magnetic architecture of the Sun, offering a potential path towards more accurate forecasts of solar activity. Helioseismic data reveal evidence for magnetically modified Rossby waves in the Sun. These global oscillations provide a new way to probe the Sun’s internal magnetic field and may help explain how solar magnetism evolves and shapes space weather.",

            "title": "Palaeoanthropological evidence from China is changing the picture of hominin evolutionary history",
            "description": "Recent palaeoanthropological discoveries in China indicate that eastern Asia had an important role in the evolutionary history of the genus Homo over the past 2 million years. New taxonomic proposals have been made to re-group archaic human fossils, including those considered to be Denisovans, as Homo juluensis and Homo longi. The hypothesis that the affinities of Yunxian 2, dated to about 1 million years ago, also infer an early divergence of the Homo sapiens lineage further underscores China’s pivotal role in global evolutionary narratives. Here we explore key biological and cultural evidence emerging from the Chinese record and its evolutionary implications, raising questions about the relationships between ‘transitional’ clades and their differing adaptive capabilities. Rather than an evolutionary cul-de-sac, China now appears as a dynamic evolutionary crossroad where multiple Homo lineages may have arisen, interacted and adapted to shifting environments. The growing fossil and genetic evidence point to a diversity of populations whose demographic history and gene flow exchange helped to shape the broader mosaic of our species. The authors review recent archaeological and palaeoanthropological discoveries from China and discuss how they change our understanding of human evolution.",
