A Palestinian protester, wearing a Guy Fawkes mask, rests during clashes with Israeli troops, following the funeral of Palestinian minister Ziad Abu Ein near the West Bank city of Ramallah December 11, 2014. Thousands of mourners turned out on Thursday for a Palestinian state funeral for a minister who died after being grabbed by the neck by an Israeli policeman at a West Bank protest, an incident that has raised tensions with Israel. Israeli and Palestinian officials issued conflicting accounts over the results of a joint Palestinian, Jordanian and Israeli autopsy on Abu Ein.

Fisherman Luovic Caloin cleans a cod aboard the Boulogne sur Mer based trawler "Nicolas Jeremy" off the coast of northern France September 23, 2013. Fishermen will not get European Union subsidies to build new vessels, EU lawmakers agreed on October 23. Voting on how to allocate nearly 1 billion euros ($1.4 billion) in annual fisheries subsidies up to 2020, the European Parliament said more money should be spent on assessing the state of Europe's depleted stocks. If confirmed in talks with governments, the proposals could spell relief for the estimated 75 percent of EU fish stocks that the European Commission says are over-fished.

Professor Karl Oldhafer, chief physician of general and visceral surgery at the Asklepios Hospital Hamburg-Barmbek, adjusts a tablet computer to access and visualize planning data during liver surgery, one of the first liver surgeries of its kind in Germany August 15, 2013. The tablet computer uses augmented reality, which allows the liver to be filmed with an iPad and overlaid during an operation with virtual 3D models reconstructed from the real organ. Developed by Fraunhofer MEVIS in Bremen, this procedure helps locate critical structures such as tumors and vessels and is expected to improve the quality of transferring pre-operational resection plans into actual surgery.
