Sep. 3, 2021 Carthamin's usage as dye dates back to ancient Egypt. But scientists only discovered its chemical structure in 2019. Now, a group of researchers has identified the genes required for the ...
Aug. 31, 2021 In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then ...
Aug. 31, 2021 Researchers report how a protein molecular motor can chop off a piece of cell membrane. The constrict-and-cut mechanism resembles that of a ratchet motor, and is of importance in processes mediating ...
Aug. 30, 2021 Against infections, tumors and inflammations, immune cells are locally positioned as rapid reaction forces in the organs of the body. On site, they specialize and take on various ...
Aug. 26, 2021 What do frog eggs have in common with 'anti-aging' creams? Their success depends on a group of chemical compounds called retinoids, which are capable of generating and re-generating ...
Aug. 26, 2021 As climate change continues to do more damage to our planet, scientists are working to find more efficient and cleaner ways to power the earth. One appealing alternative to common petrochemical ...
Aug. 26, 2021 New research has shed light on when plants first evolved the ability to respond to changing humidity in the air around them, and was probably a feature of a common ancestor of both flowering plants ...
Aug. 25, 2021 Researchers have developed a method to engineer new functionalities into ...
Aug. 24, 2021 New research shows that hamsters inoculated with spike protein gene mutants show resistance to subsequent infection with both the parental strain and the currently emerging SARS-CoV-2 alpha and gamma ...
Aug. 24, 2021 Certain proteins may have evolved to tamp down 'cheating' during meiosis, the cell-division process that gives rise to eggs and sperm. While chromosomes can tip the scales in their favor of ...
Aug. 24, 2021 A recent study led by an entomologist explores the different kinds of cells that make up mosquito immune systems. The research could shed light on how mosquitoes transmit ...
Aug. 24, 2021 Carnivorous animals lack key genes needed to detect and respond to infection by pathogens, a study has found. Farming large numbers of carnivores, like mink, could allow the formation of undetected ...
Aug. 24, 2021 There's been an age-old question going back to Darwin's time about the relationships among the world's five living rhinoceros species. One reason answers have been hard to come by is ...
Aug. 23, 2021 A team of scientists has conducted a comprehensive analysis reconstructing how kidneys form their filtering units, known as nephrons. The team studied hundreds of human and mouse nephrons at various ...
Aug. 23, 2021 The highest-ever resolution imaging of an infectious prion provides the first atomic-level data of how these abnormal proteins are assembled to cause fatal neurodegenerative diseases in people and ...
Aug. 23, 2021 Researchers have built the world's smallest mechanically interlocked biological structure, a deceptively simple two-ring chain made from tiny strands of amino acids called ...
Aug. 23, 2021 When a species diverges into two separate species, the closely resembling but non-identical copies of the ancestral gene present in the new species are called 'orthologous' genes. ...
Aug. 20, 2021 Researchers detail how a ubiquitous signaling molecule plays a critical role in male fertility, orchestrating key steps that promote sperm motility, survival and fertilization ...
Aug. 20, 2021 Researchers have isolated genetic material from exuviae (discarded exoskeletons) left after insects like cicadas molt. The researchers tested five different methods of amplifying the DNA sample by ...
Aug. 19, 2021 Researchers have developed a new way to deliver molecular therapies to cells. The system, called SEND, can be programmed to encapsulate and deliver different RNA ...
