While exploring the deep sea northeast of Hawaii’s Necker Island with a remotely operated vehicle, scientists aboard the NOAA ship Okeanos Explorer were surprised to encounter what may be a never-before-seen octopus. Though the February 27 discovery was made at a depth of 4,290 meters (14,075 feet), the octopus belongs to a group of octopods that have not previously been observed at depths greater than 4,000 meters (13,123 feet). This octopus lacks pigment cells typical of most cephalopods, which gives it a ghostlike appearance.
Early portraits looked pretty grim.A lot of old photos from the 19th and early 20th century are fraught with doom and gloom—and on the occasion the literal dead face. That led to the popular belief that people just did not smile in old photographs. The common explanation is due to the limited technology at the time to capture a smile. Exposure times were long and the thinking was it's easier to hold a serious expression over a long period.
