After 350 years, sea gives up lost jewels of Spanish shipwreck
Marine archaeologists stunned by priceless cache long hidden beneath the Bahamas' shark-infested waters It was a Spanish galleon laden with treasures so sumptuous that its sinking in the Bahamas in 1656 sparked repeated salvage attempts over the next 350 years. So when another expedition was launched recently, few thought that there could be anything left – but exquisite, jewel-encrusted pendants

The Dangers of Saying "Patient Zero"
T his summer, yet another disease unfamiliar to most people in the United States is being transmitted around the world—as is the impulse to find someone to blame. Many news stories about the current monkeypox outbreak make reference to a "patient zero," supposedly the one person who brought the virus into a particular state or community. This kind of finger-pointing, which long predates monkeypox

TRIM28-dependent SUMOylation protects the adult ovary from activation of the testicular pathway
Nature Communications, Published online: 29 July 2022; doi:10.1038/s41467-022-32061-1 Gonadal fate in mammals is determined during embryogenesis and is actively maintained in adulthood.

Communication makes hunting easier for chimpanzees

Pathogen-selective killing by guanylate-binding proteins as a molecular mechanism leading to inflammasome signaling
Nature Communications, Published online: 29 July 2022; doi:10.1038/s41467-022-32127-0 Guanylate-binding proteins (GBP) have a function in inflammasome formation and pathogen defence. Here the authors show that these GBP proteins are able to kill certain bacteria and promote selective inflammasome activation and that this is mediated by specific GBP protein regions.
