A tiny organism is mysteriously repairing its DNA to defy death in Chernobyl

Microscopic nematodes living in the Chernobyl Exclusion Zone have demonstrated remarkable resilience to radiation, showing no signs of genetic damage despite their exposure to one of the most radioactive environments on Earth. This surprising discovery, published in the Proceedings of the National Academy of Sciences, suggests that these tiny worms may possess unique DNA repair mechanisms that could have implications …

Greenland sharks have massive genomes. Scientists think they could be the reason behind 400-year-long lifespans

CNN

Sign up for CNN’s Wonder Theory science newsletter. The researchers want to explore and analyze the Greenland shark’s DNA further, while also comparing its genome with other shark species and shorter-lived fish, to provide additional evidence for this unique trait, Hoffman said. “Identification of the genetic basis of lifespans across different species, including long-lived sharks, allows researchers to understand the …

Chinese researchers map pan-genome of rice

China Daily

BEIJING -- Chinese researchers have presented nearly complete genomes of 13 representative wild rice species and constructed an ultra pan-genome map of rice. By integrating with four previously published genomes for pan-genome analysis, the researchers from the Jiangxi Academy of Agricultural Sciences and Hebei University identified a total of 101,723 gene families of rice. Additionally, the researchers identified 7,048 resistance …

New analysis of Wuhan market samples reveal 'specific species' potential carriers of COVID-19 virus

Deccan Chronicle

New Delhi: Along with raccoon dogs, considered a prime suspect for passing on the COVID-19 virus to humans, civet cats and bamboo rats are among a list of potential 'intermediate' host animals that were sold at Wuhan's seafood market -- the pandemic's epicentre -- and may have served as a conduit for the pathogen, according to a new study.Bamboo rats, …

With their primary goal to advance scientific knowledge, most scientists are not trained or incentivized to think through the societal implications of the technologies they are developing. In 2015, three years after scientists discovered how to permanently edit the human genome, U.S. scientists issued a statement to halt applications of germline genome editing, a controversial type of gene editing where …

Humble fern from New Caledonia boasts world's largest genome

The Hindu

New research shows that a fork fern species, called Tmesipteris oblanceolata, has a genome — all the genetic information of an organism — that is 7% larger than that of the previous record-holder, the Japanese flowering plant Paris japonica, and more than 50 times the size of the human genome. The metric for genome size was the number of base …
