Kiran Mazumdar-Shaw talks about India’s battle with Covid-19 In an interview with DNA, Kiran Mazumdar-Shaw, Chairperson and Managing Director, Biocon, talks about India’s battle with Covid-19 and how the country is faring with its vaccination program. She also discusses the need for more investment in the healthcare sector, the development of the biotechnology industry and the importance of innovation in tackling the pandemic. She emphasizes the need for collaboration between industry, government and civil society to effectively tackle the pandemic.
Ancient DNA used to map evolution of fever-causing bacteria | ScienceDaily
Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.
'Selfish' genes called introners proven to be a major source of genetic complexity
DNA is the genetic code that provides the biological instructions for every living species, but not every bit of DNA helps the species survive. Some pieces of DNA are more like parasites, along for the ride and their own survival.
Ancient DNA used to map evolution of fever-causing bacteria
Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.
Ancient DNA sheds light on evolution of relapsing fever bacteria

What DNA from the bottom of the sea can tell us about the history of marine mammals in the Arctic | Research Communities by Springer Nature
DNA from four Northern Greenland marine sediment cores offer a detailed record of marine mammal occurrences across the past 12,000 years. The findings reveal a strong correlation between marine mammal presence and deglaciation events at the onset of the Holocene.
How rapid DNA repair in plants protects genomes from internal threats
Scientists have uncovered a critical role for rapid DNA repair in maintaining genome stability. A new study reveals that repair of double-strand breaks (DSBs) in nuclear DNA in plants serves as a powerful safeguard against the integration of foreign DNA from chloroplasts—a phenomenon that, while important for evolution, can be highly destabilizing to the genome. The research expands our knowledge about plant genome evolution and also has relevance to the medical field.
