The precise transmission of genetic information from one generation to the next is fundamental to life. Most of the time, this process unfolds with remarkable accuracy, but when it goes awry, mutations can arise—some of them beneficial, some of them inconsequential, and some of them causing malfunction and disease.

Playing professional football games in empty stadiums had a hugely negative effect on the success of home teams, with home advantage almost halved, according to new research. The study used the unique opportunity presented by the COVID-19 pandemic to test whether home advantage applies when fans are not present in the stands. They found that home teams accrued significantly fewer points and scored fewer goals when crowds were absent.

Researchers recently reported that magnetic resonance imaging (MRI) could reduce overdiagnoses and thereby improve prostate cancer screening. Now, the same research group shows that the addition of a novel blood test, the Stockholm3 test, can reduce the number of MRIs performed by a third while further preventing the detection of minor, low-risk tumors.

PARP inhibitors, used to treat patients with cancer of the breast, ovaries, prostate and pancreas, work by inducing persistent DNA gaps in tumor cells with BRCA1 and BRCA2 mutations. The discovery offers the potential to monitor tumors for the development of resistance to PARP inhibitor therapy, and to identify drug combinations that could prevent drug resistance and improve the efficacy of cancer therapies.
