Gary Wilson of Fairfield, Connecticut, was awarded a posthumous Navy and Marine Corps Medal during a memorial service attended by hundreds of fellow service members, friends and family members at Marine Corps Recruit Depot San Diego. His son, Ian, accepted the commendation, the highest noncombat decoration awarded for heroism by the Department of the Navy.Wilson, who died in a motorcycle accident on Interstate 15 in Temecula on Nov. 16, received the award in recognition of his lifesaving actions on state Route 163 in the Miramar area late last summer.The 33-year-old serviceman was riding his motorcycle on the northern San Diego freeway on the morning of Sept. 18 when he came upon the scene of a pileup that left one car burning. He stopped, pulled two women from the wreckage and helped get them out of harm’s way.“I was doing my job as a Marine,” Wilson said. “We’re here to serve the people. Not just during wartime, but all the time.”During the memorial service, USMC Lt. Col. David Becker, commanding officer of 3rd Recruit Training Battalion, said Wilson had  “positively affected thousands of lives.”“Former President Ronald Reagan once said that some people spend an entire lifetime wondering if they made a difference in this world,” Becker said. “Marines don’t have that problem, and Sergeant Wilson doesn’t have that problem.”The West Coast Drill Instructors Association has donated a brick displaying Wilson’s name to be added to the Drill Instructor Monument at the recruit depot near Lindbergh Field where he was stationed.“We extend our deepest condolences to the family and friends of Sergeant Wilson,” said Brig. Gen. Ryan Heritage, commanding general of MCRD San Diego. “Our thoughts and prayers are with them during this difficult period. This is truly the loss of a fine Marine, and he will be missed greatly.”Wilson enlisted in the Marine Corps in March 2010. He was assigned to the recruit depot as a drill instructor in March 2016 after service in Okinawa, Japan, and at Camp Pendleton.His personal awards include two Good Conduct Medals, three Sea Service Deployment Ribbons, a National Defense Service Medal and a Global War on Terrorism Service Medal.

Shipworm that eats rock instead of wood found in river in the

first_imgThey were not able to determine the motives behind the rock boring by the shipworms, but note that it is not likely a means of obtaining any sort of nutritional value. They suspect the little mollusks meet their nutritional needs courtesy of bacteria that live in their gills—though they have not ruled out the possibility of food being pulled into its siphon. © 2019 Science X Network Shipworms are water-dwelling bivalve mollusks—they are well known because of their tendency to chew through wood and digest it. They came to prominence during the heyday of wooden ships—the small mollusks would bore holes in them, at times making them unfit to sail. More recently, they are known for making holes in piers and other wooden structures used in the water. In this new effort, the researchers have found a species of shipworm that does not eat wood at all, but instead bores through limestone.The researchers report that the new kind of shipworm was actually first spotted back in 2006, but it was not until recently that it was carefully studied. After capturing specimens by breaking open the rocks they occupied, the researchers put them in tanks in their lab. They report that the shipworms were small—on the order of 150 millimeters long. They were white and more closely resembled worms than other mollusks. They also differed physically in significant ways from wood-eating shipworms—for instance, they have larger, flatter teeth more suited to boring through rock. The rock borers also lacked the sac used by wood eaters to digest wood. The researchers suggest that such physical differences indicate that the rock-eating shipworm likely did not evolve from its wood-eating relatives, but more likely diverged from them a very long time ago. The shipworms were observed to gnaw their way into the limestone. A little while later, the researchers observed the shipworms excreting sand. Journal information: Proceedings of the Royal Society B Explore further A team of researchers affiliated with several institutions in the U.S. has found and identified a species of shipworm that eats rock instead of wood. In their paper published in Proceedings of the Royal Society B, the group describes their study of the bivalve and what they found. The river bedrock is shaped by large holes bored by the shipworm.
