What happens to marine life when oxygen is scarce?

A recent study investigated the impact of deoxygenation on Caribbean Ocean floor ecosystems and found that coral microbes are surprisingly resilient. Despite the death of macro-organisms, coral microbes rapidly recover after hypoxic events subside, suggesting an independent recovery route from benthic macro-organisms.

Genomic test could help predict aggressive disease in men newly diagnosed with prostate cancer

A new genomic test may help identify patients at high risk of prostate cancer progression. The Decipher Biopsy test showed that men with high scores needed active treatment sooner, and those who underwent surgery had shorter time until PSA levels increased or they were put on anti-androgen therapy.
