Feb. 28, 2024 New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once ...
Aug. 23, 2023 What was once the final frontier of the human genome -- the Y chromosome -- has just been mapped out in its entirety. Scientists used advanced sequencing technologies to read out the full DNA ...
Apr. 8, 2021 A full assembly of human chromosome 8 has now been completed. Its DNA content and arrangement are of interest in primate and human evolution, in several immune and developmental disorders, and in ...
Apr. 20, 2022 A new study of genetic data of more than 400,000 UK adults has revealed a clear link between walking pace and a genetic marker of biological ...
Dec. 2, 2021 DNA damage signaling induced by aging telomeres increases the expression of ACE2, the human SARS-CoV-2 cell receptor, scientists ...
Mar. 22, 2023 Changes in the brain caused by Alzheimer's disease are associated with shortening of the telomeres -- the protective caps on the ends of chromosomes that shorten as cells age -- according to a ...
Sep. 22, 2022 A new mechanism that slows down and may even prevent the natural aging of immune cells -- one of the nine 'hallmarks of ageing' -- has been identified by an international ...
Feb. 15, 2024 Study shows how telomerase can run amok, deleteriously capping damaged DNA, were it not for a first responder to DNA ...
Aug. 23, 2023 Highly challenging to sequence and long overlooked, the human Y chromosome's contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the ...
Oct. 31, 2023 Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely ...
