Facebook gets into the meme-making biz with experimental Whale app
The app was quietly released in Canada last weekThe app’s listing confirms that it’s been developed by Facebook’s New Product Experimentation (NPE) team, which was set up earlier this year to develop new experimental apps for the social media giant. At the time, Facebook said it was using the separate brand name to set the expectation that its apps could change rapidly, or even shut down if the company finds that they’re not useful for people. NPE is also credited with releasing two other apps called Bump and Aux. A Facebook spokesperson told The Information that the apps are intended to help the company discover new features and services that people like.

WASHINGTON (Reuters) - Using a bright orange electrocardiogram machine attached with suction cups to the body of a blue whale, scientists for the first time have measured the heart rate of the world's largest creature and came away with insight about the renowned behemoth's physiology.
The blue whale, which can reach up to 100 feet (30 meters) long and weigh 200 tons, lowers its heart rate to as little as two beats per minute as it lunges under the ocean surface for food, researchers said on Monday. The maximum heart rate they recorded was 37 beats per minute after the air-breathing marine mammal returned to the surface from a foraging dive.
Manta Rays And Whale Sharks Are Consuming A Staggering Amount Of Plastic
Manta rays and whale sharks are among the largest filter-feeding fishes on the planet. To power their bulk, they sieve massive quantities of plankton out of the water. But new research off the coast of Indonesia suggests their meals come with an unwanted garnish: an alarming amount of plastic waste. The waters around Indonesia are rich with plankton and provide ample feeding opportunities for mantas and whale sharks. Unfortunately, these same feeding grounds are also where our trash tends to accumulate: Indonesia is the world’s second-largest marine plastic polluter, and waves and currents concentrate much of that material nearshore.
The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whale parvorder, Mysticeti. At up to 29.9 meters (98 ft) in length and with a maximum recorded weight of 173 tonnes (190 short tons), it is the largest animal known to have ever existed.
The Blue Whale ’ s Heart Beats at Extremes. For the first time, scientists recorded a cardiogram Goldbogen began to wonder whether, by adding electrodes to the suction cups , he could also capture a heartbeat. During dives, the whale ’ s heart rate plummeted to four to eight beats a minute, and
"The blue whale is the largest animal of all-time and has long fascinated biologists," said Stanford University marine biologist Jeremy Goldbogen, who led the study published in the journal Proceedings of the National Academy of Sciences.
"In particular, new measures of vital rates and physiological rates help us understand how animals work at the upper extreme of body mass," Goldbogen added. "What is life like and what is the pace of life at such a large scale?"
Generally speaking, the larger the animal, the lower the heart rate, minimizing the amount of work the heart does while distributing blood around the body. The normal human resting heart rate ranges from about 60 to 100 beats per minute and tops out at about 200 during athletic exertion. The smallest mammals, shrews, have heart rates upwards of a thousand beats per minute.
Facebook launched an experimental meme app called Whale – here's how it works
Facebook quietly launched a meme creation app called Whale, which lets people layer doodles, emojis, and other visual effects over their own photos or stock images. It's essentially a simple image-editing tool, designed to create shareable visuals for social.Whale is only available in Canada's App Store for now and was created by Facebook's experimental apps team.We tried Whale to find out how it works.Visit Business Insider's homepage for more stories.Facebook has quietly launched an image-editing app called Whale, intended to generate memes that can be easily edited and shared across different social and messaging apps.
When a blue whale washed up in Newfoundland in 2014, Jacqueline Miller launched into action. German anatomists soak the heart in acetone, constantly changing out the fluid. Over six months, the acetone replaces all the water molecules in the tissue.
SCIENCE You’ve probably heard claims that a blue whale ’ s heart is the size of a car, and that people could swim through their aortas. The blue whale is the largest animal ever to have lived. One urban legend says that its heart is as big as a Volkswagen Beetle! For the first time, scientists have tested
The researchers created a tag device, encased in an orange plastic shell, that contained an electrocardiogram machine to monitor a whale's heart rhythm swimming in the open ocean. The device had four suction cups to enable them to attach it to the whale non-invasively.
The researchers obtained nine hours of data from an adult male whale about 72 feet (22 meters) long encountered in Monterey Bay off California's coast.
"First we have to find a blue whale, which can be very difficult because these animals range across vast swaths of the open ocean. By combining many years of field experience and some luck, we position a small, rigid-hulled, inflatable boat on the whale's left side," Goldbogen said.
"We then have to deploy the tag using a six-meter (20-foot) long carbon-fiber pole. As the whale surfaces to breathe, we tag the whale in a location that we think is closest to the heart: just behind the whale's left flipper," Goldbogen added.
Baleen whales such as blue whales, despite their immense size, feed on tiny prey. As filter-feeders, they take huge amounts of water into their mouths and strain out prey including shrimp-like krill and other zooplankton using baleen plates made of keratin, the same material found in fingernails.
During feeding dives, the whale exhibited extremely low heart rates, typically of four to eight beats per minute and as low as two. After surfacing to breathe following foraging dives, the whale had heart rates of 25 to 37 beats per minute.

A network of deep-sea cables near Monterey Bay, California, is helping researchers detect seismic activity at the bottom of the ocean. Researchers used the cables to record a 3.5-magnitude earthquake in Gilroy, California. They also used them to discover a new fault system near the San Andreas Fault, which runs along the California coast. The technology could eventually be used to map fault lines in uncharted areas.
