If you were in the audience for Oussama Khatib's IROS keynote in Hamburg last year, you may remember him talking about this crazy thing: We, of course, cornered Oussama immediately afterwards, because humanoid robotic submarine what?! It turned out that OceanOne, as it was called, was involved in a top secret (or something) project in collaboration with the French, which has (now that it's over and wasn't a disaster) been un-topsecretified so we can finally, finally tell you about it. Originally, OceanOne was not an archaeological robot--it was conceptualized by King Abdullah University of Science and Technology (KAUST) in Saudi Arabia as a way of monitoring deep coral reefs in the Red Sea. Christian Voolstra, assistant professor of marine science at KAUST's Red Sea Research Center, explained where the idea came from in an interview last year: Currently people use a so-called ROV (remote operated vehicle), which is a little submarine with two robotic arms and very limited dexterity. Using the ROV to examine delicate coral colonies proved to be troublesome.
The most common artifacts that survive are clay storage jars known as amphorae. These were used by merchant ships throughout antiquity to transport cargoes of wine, olive oil, fish sauce, and other goods. It's possible to identify the place of origin for different amphorae by analyzing the style of the jars and the elements in the clay: different pottery workshops made visually distinct vessels by firing clay sourced from local soils. The amphorae recovered in 2016 originated in Cyprus, Egypt, Samos, Patmos, Asia Minor, mainland Greece, Rome, Spain, and even North Africa, revealing the vast web of trade and commerce that crisscrossed the many cultures of the Mediterranean throughout history.
There was less than three minutes to play in Friday's women's Olympic water polo final when the emotions started to kick in for Adam Krikorian. No women's team had ever won consecutive gold medals in the sport, something Krikorian's team was about to do. No team had ever scored more goals, given up fewer or won by a larger margin than Krikorian's U.S. team did in its 12-5 rout of Italy. Yet Krikorian's emotions had nothing to do with joy or accomplishment. Two days before the opening ceremony of the Rio Games, Krikorian's brother Blake was found dead in his car at a Northern California beach.
The U.S. became the first two-time Olympic champion in women's water polo history Friday, blitzing Italy, 12-5, at Rio's Olympic Aquatics Stadium. The U.S. won its first gold in London four years ago but just four women -- Maggie Steffens, Kami Craig, Melissa Seidemann and Courtney Mathewson -- from that team played in Rio. All four scored in Friday's final, though, with Steffens' third-period goal giving her a tournament-high 17. The U.S., which trailed just once for less than a minute in six games in Rio, took the lead for good on Kiley Neushul's goal less than four minutes into the first period. By the end of the opening eight minutes, the Americans led 4-1 and were never seriously challenged after that.
