Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes, and Antarctic ice. They are usually 6–25 mm (0.24–0.98 in) long. Most species have 20 body segments, bearing 11 pairs of leaf-like phyllopodia, and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces, with the exception of Branchinecta gigas, or "giant fairy shrimp", which is itself a predator of other species of anostracans. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families.
Heterotrophic picoplankton is the fraction of plankton composed by cells between 0.2 and 2 μm that do not perform photosynthesis. They form an important component of many biogeochemical cycles.

The Jiufotang Formation is an Early Cretaceous geological formation in Chaoyang, Liaoning which has yielded fossils of feathered dinosaurs, primitive birds, pterosaurs, and other organisms. It is a member of the Jehol group. The exact age of the Jiufotang has been debated for years, with estimates ranging from the Late Jurassic to the Early Cretaceous. New uranium-lead dates reveal the formation is deposited in the Aptian stage of the Early Cretaceous. Fossils of Microraptor and Jeholornis are from the Jiufotang.
The Tiaojishan Formation is a geological formation in Hebei and Liaoning, People's Republic of China, dating to the middle-late Jurassic period. It is known for its exceptionally preserved fossils, including those of plants, insects and vertebrates. It is made up mainly of pyroclastic rock interspersed with basic volcanic and sedimentary rocks. Previously, the Tiaojishan Formation was grouped together with the underlying Haifanggou Formation as a single "Lanqi Formation." The Tiaojishan Formation forms a key part of the Yanliao Biota assemblage, alongside the Haifanggou Formation.
Branchinecta gaini is a species of fairy shrimp from Antarctica and Patagonia. It is the largest freshwater invertebrate in Antarctica, at 16 mm (0.63 in) long. It lives on bacteria and other organisms, surviving the winter as resting eggs.
Wumengosaurus is an extinct aquatic reptile from the Middle Triassic Guanling Formation of Guizhou, southwestern China. It was originally described as a basal eosauropterygian and usually is recovered as such by phylogenetic analyses, although one phylogeny has placed it as the sister taxon to Ichthyosauromorpha while refraining from a formal re-positioning. It was a relatively small reptile, measuring 95.5–130.5 cm (3.13–4.28 ft) in total body length.
Microcystis aeruginosa is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. Microcystis aeruginosa produces numerous congeners of microcystin, with microcystin-LR being the most common. Microcystis blooms have been reported in at least 108 countries, with the production of microcystin noted in at least 79.
In molecular biology mir-397 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
Penicillium decumbens is an anamorph species of the genus of Penicillium which occurs widespread in nature, mainly in subtropical and tropical soil but it also occur in food. Analysis have shown that Penicillium decumbens has antibiotic activity Penicillium decumbens produces the cyclopentenone cyclopenicillone
Sinotaia quadrata is a species of a freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae. It is widely distributed and common species in China and in northern Vietnam inhabiting various shallow freshwater habitats, where it can reach high densities. It is a keystone species in its habitat and can significantly affect water quality and phytoplankton communities. It is commonly used in Chinese cuisine.
The TianQin Project is a proposed space-borne gravitational-wave observatory consisting of three spacecraft in Earth orbit. The TianQin project is being led by Professor Luo Jun, President of Sun Yat-sen University, and is based in the university's Zhuhai campus. Construction on project-related infrastructure, which will include a research building, ultra-quiet cave laboratory, and observation center, began in March 2016. The project is estimated to cost 15 billion RMB, with a projected completion date in the mid-2030s. In December 2019, China launched Tianqin-1, a technology demonstration.
CKLF-like MARVEL transmembrane domain-containing protein 3, also termed chemokine-like factor superfamily 3, is a member of the CKLF-like MARVEL transmembrane domain-containing family of proteins. In humans, CMTM2 protein is encoded by the CMTM3 gene located in band 22.1 on the long arm of chromosome 16. This protein is expressed in a wide range of tissues, including fetal tissues. It is highly expressed in the male reproductive system, particularly testicular tissues and may play a role in the development of this tissue. It is also highly expressed in the immune system including circulating blood cells, i.e. B lymphocytes, CD4+ T lymphocytes, and monocytes. However, CMTM3 protein is weakly expressed or unexpressed in the malignant tissues of several types of cancers. In many but not all of theses cancers, this decreased or lack of expression appears due to methylation of the GpC islands in the promoter region, and thereby the silencing, of the CMTM3 gene.

He has researched the vegetational and environmental history over the past 10–20,000 years in many parts of the world, including Fennoscandia, UK, Minnesota, the Yukon, Siberia, and Tibet.
The Sinopharm WIBP COVID-19 vaccine, also known as WIBP-CorV, is one of two inactivated virus COVID-19 vaccines developed by Sinopharm. Peer-reviewed results show that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases. The other inactivated virus COVID-19 vaccine developed by Sinopharm is the BIBP vaccine (BBIBP-CorV) which is comparably more successful. 1 billion doses are expected to be produced per year.
