Scientists from the Institute of Vertebrate Paleontology and Paleoanthropology have discovered two fossil repositories in the early Silurian strata in southwestern Chongqing and Guizhou, which are rewriting the evolutionary story of "from fish to human".
A research team has now conducted a study of yunnanozoans, extinct creatures from the early Cambrian period, and discovered evidence that they are the oldest known stem vertebrates. The term stem vertebrate refers to those vertebrates that are extinct, but very closely related to living vertebrates.
An international research team led by Dr. ZHANG Huaqiao from the Nanjing Institute of Geology and Palaeontology has used hundreds of new fossil specimens to clarify the anatomy and evolutionary affinity of Saccorhytus, originally thought to be a deuterostome.
The Insight-HXMT team has recently discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary Swift J0243.6+6124, corresponding to a surface magnetic field of more than 1.6 billion Tesla.
Evolutionary chromosomal changes may take a million years in nature, but researchers are now reporting a novel technique enabling programmable chromosome fusion that has successfully produced mice with genetic changes that occur on a million-year evolutionary scale in the laboratory.
Emma Lavaut and her colleagues found that a species of red seaweed uses the isopod crustacean Idotea balthica to transfer its male gametes for fertilization. Researchers recently concluded that the significantly expands the phylogenetic and temporal scope of animal-mediated male gamete movement, bringing the concept of "pollination" from plants to algae.
The hybrid magnet at the Steady High Magnetic Field Facility in Hefei, China set a world record for the highest steady magnetic field by a working magnet when it produced a steady field of 45.22 tesla on Aug. 12. It broke the previous world record of 45 tesla set in 1999.
A team of astronomers led by Prof. HAN Zhanwen from the Yunnan Observatories and Prof. Chris Wolf from Australian National University has jointly discovered a binary system ejecting a common envelope at a speed of about 200 kilometers per second.
Researchers from the Xishuangbanna Tropical Botanical Garden have identified three species of Vespa hornets that help move most Aquilaria sinensis seeds to more suitable places before they lose viability by eating the plant's fruit.
