一 |     SEQUOIA NATIONAL PARK, Calif. -- A pilot from France who disappeared while hiking California's towering Mount Whitney was found dead after falling about 1,000 feet (305 meters) off a cliff, the National Park Service said Friday.The hiker was identified as Tom Gerbier of Fontenay-sous-Bois, France, who was a pilot for Air France, the park service said in a statement. He was 38, according to a missing poster issued by the Inyo County Sheriff's Office, which was part of the search. The tallest mountain in the contiguous United States, Mount Whitney rises 14,494 feet (4,418 meters) on the eastern border of Sequoia National Park and is a difficult but popular hike. Gerbier started out at Whitney Portal near the town of Lone Pine early Tuesday and was reported missing when he didn't show up for his return flight Wednesday, the park service said. The park service and local authorities sent ground teams to the area Thursday.The searchers spotted clues that someone may have fallen off a cliff in an area called “The Notch,” and a helicopter crew directed there spotted a motionless person in clothing matching Gerbier's description.The body was recovered by helicopter that evening, and the Tulare County Sheriff's Office confirmed Gerbier's identity. Air France said in a statement that Gerbier had been on a stopover in Los Angeles, the San Francisco Chronicle reported. "The company offers its most sincere condolences to his family and loved ones,” the airline said.。据1月13日《科学技术日报》官方微博报道，1月12日，湖北省武汉市中科院水产研究所展出了一只白鳍豚的3D打印标本。这是我国第一个三维印制生物标本。据报道，“齐琪”被认为是最后一只白海豚，在2002年被囚禁22年后死亡。3-D打印样本长2.07米，重约7公斤。它是从三维打印构建的“冰淇淋”三维数据模型中恢复出来的。据报道，“奇奇”是世界上最长的圈养海豚。1980年被渔民捕获并送往水生栖息地。

二 | 自从2002年它死后，没有人见过活海豚。

三 | 白鳍豚（学名：白鳍豚，lipotes vexillifer），又名：白鲸、白鳍、白旗、白夹、绿鳍、琵琶、中国鼠海豚、长江鼠海豚、长江河豚，是我国特有的淡水鲸种，只产于长江中下游。

四 | 20世纪80年代，由于各种原因，海豚的数量急剧下降。2002年，据估计有不到50只海豚，被称为“水中大熊猫”。海豚属于自己的家族，被列为国家一级保护野生动物和世界上12种最濒危动物之一。

五 | 2007年8月8日，一份报告发表在《英国皇家学会生物学快报》上，正式宣布了海豚的功能性灭绝。
