Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond our Milky Way Galaxy. FRB emission characteristics favor magnetars as their sources, as evidenced by FRB-like bursts from a magnetar in the Milky Way, and the star-forming nature of FRB host galaxies. However, the processes that produce FRB sources remain unknown. According to new research

DNA methylation is one of several epigenetic mechanisms crucial for regulating gene expression in eukaryotic organisms. Arabidopsis thaliana. Image credit: Carl Davies, CSIRO / CC BY 3.0. DNA methylation is a normal biological process in living cells wherein small chemical groups called methyl groups are added to DNA. This activity controls which genes are turned

A new genus and species of early-diverging oviraptorosaurian dinosaur has been identified from two specimens found in Inner Mongolia, China. Life reconstruction of Yuanyanglong bainian.

Administrative innovations in south-west Asia during the 4th millennium BCE, including the cylinder seals that were rolled on the earliest clay tablets, laid the foundations for proto-cuneiform script, one of the first writing systems. Seals were rich in iconography, but little research had focused on the potential influence of specific motifs on the development of

Using genome, transcriptome, and proteome analysis of the newly-discovered species of tardigrade, named Hypsibius henanensis, scientists explored the molecular basis contributing to radiotolerance in these tiny invertebrates.

Tardigrades, also known as water bears or moss piglets, are a diverse

The NASA/ESA Hubble Space Telescope has taken a picture of the barred spiral galaxy NGC 1672, which is visible from the southern hemisphere. This Hubble image shows NGC 1672, a barred spiral galaxy some 49 million light-years away in the constellation of Dorado. The color image was made from separate exposures taken in the ultraviolet

Named LID-568, this 7.2-million-solar-mass black hole appears to be feeding on matter at a rate 40 times its Eddington limit and is seen as it existed just 1.5 billion years after the Big Bang.
