The team observed the gentle giants two days in a row. Blue whales can be found in every ocean except the Arctic. Breakthroughs, discoveries, and DIY tips sent six days a week. As if soaring above the brilliant blue ocean isn't spectacular enough, the New England Aquarium's aerial survey team recently experienced two back-two-back sightings of blue whales --a little déjà blue, per the aquarium's clever social media post. The first sighting occurred on February 27, when scientists from the Aquarium's Anderson Cabot Center for Ocean Life spotted a blue whale ().

Smartphones, like many consumer products, arrive in the US on giant container ships, vessels that are leading killers of endangered whales that play crucial roles in the climate and ocean health. Now a high-tech initiative called Whale Safe is detecting the huge marine mammals off the coast of San Francisco and alerting ship captains to slow down to avoid deadly collisions. Launched on Wednesday, Whale Safe aims to create "school zones" for imperiled blue whales, fin whales and humpback whales in busy shipping lanes, according to the project's managers at the Benioff Ocean Science Laboratory at the University of California at Santa Barbara and at the Bay Area's Marine Mammal Center. Speeders are caught by satellite surveillance and cited online. That gives consumers the opportunity to see, for instance, if that cruise they're contemplating is operated by a company with a history of ignoring sea speed limits.

Blue whales swim to the surface to feed on krill as it helps them to conserve energy, according to a new study that involved amazing drone footage of the mammals. Experts from Oregon State University found that feeding on the ocean's surface plays an important role in the hunt for food among New Zealand blue whales. Blue whales are the largest mammals on Earth and have to carefully balance the cost of energy they get from food with the cost of energy used in getting the food. Researchers say the marine mammals forage for krill in areas where they are densely packed and found near the surface of the water to cut their dive time. The Oregon team found that the blue whales do this to conserve on the energetic costs of feeding such as diving, holding their breath or opening their mouths.

Watch: This may be the first footage of a blue whale "heat run." Blue whales are the largest animals on Earth, but we know surprisingly little about their complex social interactions--and they've rarely been recorded on camera. But new footage filmed off the coast of Sri Lanka by pro whale photographer Patrick Dykstra, in conjunction with blue whale scientist Howard Martenstyn, may be a first. Their video shows what they believe is the first known clip of a blue whale "heat run." Heat runs have been well documented in humpback whales, but no known footage exists of the behavior in blue whales (or at least that Dykstra or National Geographic could find).

In drone footage captured on May 18 in Monterey, California, a group of orcas is seen carrying out a coordinated attack on a blue whale. Orcas, also known as killer whales, are known to prey on other marine mammals, including dolphins and seals. But even these fearsome predators don't stand much of a chance against a mature blue whale: The largest animal on the planet, an adult blue whale can reach up to a hundred feet long and weigh close to 200 tons. In this instance, the large blue whale flipped on its side, sending up what seemed like a wall of water, and swam away at a speed that far outpaced the orcas, says marine biologist Nancy Black, who captured the event from on board a whale-watching boat. The real reason the orcas likely orchestrated an attack? "They were probably doing it for the heck of it," says Black. "They play with [whales] like cats play with their prey.

The first neural network was proposed in 1943. In 1949, the math was worked out, and in 1959, the first successful neural network was built. Seat-belts were not standard equipment on cars. Transistor computers had a total of 1 in existence at the time. Nothing in the technology has substantially changed in all of those years.

Scientists filming in the South Ocean off the coast of New Zealand captured this stunning footage of a blue whale eating a mass of krill. When you weigh 200 tons, even the smallest body movements require a lot of energy. That's why blue whales, Earth's largest animal, are picky eaters. Stunning new drone footage shows exactly how these massive mammals maneuver to feed on only the most nutritious patches of krill--providing insight on how they make these choices. Captured by a research team led by National Geographic Explorer Leigh Torres from Oregon State's Marine Mammal Institute, footage filmed in the Southern Ocean near New Zealand shows the moment a whale spots a patch of krill and sizes up whether it's worth expending energy.
