Oregon scientists uncover sub-atomic instruments that produce DNA harm in sperm Kumar Jeetendra | October 25, 2020 University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat. In humans, the optimal temperature for sperm production is just below body temperature, in a range of approximately 90-95 degrees F. Human studies have found …
Retroviruses attacking the koala germline add to high malignant growth rates Kumar Jeetendra | February 26, 2021 Koalas are facing multiple ecological and health issues which threaten their survival. Together with habitat loss – accelerated by last year’s devastating bush fires — domestic dog attacks and road accidents, they suffer from fatal chlamydial infections and extremely high frequency of cancer. The results are reported in the journal Nature Communications. The koala retrovirus …
