Coronary artery disease may have persisted in human populations because the genes that cause this late-striking disease also contribute to having a greater numbers of children.

Scientists have identified a molecular pathway by which some types of human papilloma virus (HPV) might increase the risk of skin cancer, particularly in people with the rare genetic disorder epidermodysplasia verruciformis (EV).

Cancer cells might streamline their genomes in order to proliferate more easily, new research suggests. The study, conducted in both human and mouse cells, shows that cancer genomes lose copies of repetitive sequences known as ribosomal DNA. While downsizing might enable these cells to replicate faster, it also seems to render them less able to withstand DNA damage.

Scientists have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). The discovery could improve the performance of fuel cells that run on hydrogen fuel but can be poisoned by CO.

Researchers have developed an exoskeleton system that provides personalized support for its user. In healthy volunteers, the optimized exoskeleton reduced energy expenditure during walking by 24 percent, on average, compared to when the system was not providing personalized support.

Scientists are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle's protein shell. This work could benefit research in bioenergy and pathogenesis, and it could lead to new methods of bioengineering bacteria for beneficial purposes.
