The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn't, however, clarify why older fathers pass ...

A team of researchers at the Max Planck Institute for Heart and Lung Research, working with a colleague from Temple University, has found that transcriptional adaptation appears to play a role in inherited epigenetic changes.
After an intrepid, decade-long search, Johns Hopkins Medicine scientists say they have found a new role for a pair of enzymes that regulate genome function and, when missing or mutated, are linked to diseases such as brain ...

A team of researchers affiliated with multiple institutions in Japan, working with colleagues from Vietnam, Cambodia, Singapore, Taiwan, Indonesia and Ghana, has found evidence of mosquitoes that are highly resistant to common ...
Scientists at Johns Hopkins Medicine say they have developed a computer model—dubbed quantitative fate mapping—that looks back in the developmental timeline to trace the origin of cells in a fully grown organism. The ...

More than 50 years, ago researchers discovered that plants can sense carbon dioxide (CO2) concentrations. As CO2 levels change, "breathing" pores in leaves called stomata open and close, thus controlling evaporation of water, ...
