World’s biggest active geyser erupts at Yellowstone National Park for third time in weeksSteamboat Geyser, in Yellowstone National Park, erupted at around 6.30am local time on Friday morning, geologists said. The eruption is the latest event in a rare period of activity at the geyser this year, following similar water discharges on March 15 and April 19 this year. Before this year, Steamboat had not erupted since September 2014.

Following last month’s Parkland school massacre in Florida, Trump held a remarkable meeting with a bipartisan group of senators at the White House, where he talked up proposals aimed at curbing gun violence. The president expressed support for ideas backed by Democrats, like universal background checks and raising the minimum age to purchase an assault-style weapon.

World’s first talking killer whale: Wikie the orca learns to say ‘hello’ and ‘bye bye’

World’s first talking killer whale: Wikie the orca learns to say ‘hello’ and ‘bye bye’Whales are known for their impressive communications skills which allow pods to ‘talk’ to each other through complex clicks and singing, even when they are 100 miles apart. But a new experiment has shown the mammals are also apparently capable of mimicking human speech, a feat that was previously believed to be limited to primates, birds, elephants, dolphins and seals. Scientists say they have recorded a killer whale named Wikie repeating the words ‘hello’ and ‘bye bye’, counting up to three, and even saying the name of her trainer ‘Amy.’ The 14-year-old orca lives in Marineland at Antibes, France, and is the first in the world ever recorded by scientists allegedly saying human words. The achievement is even more remarkable because whales do not have the same vocal ability as humans having evolved to make their own sounds underwater. While humans use the larynx to speak, whales produce sounds through their nasal passages using bursts of air. An orca whale in the wild  Recently scientists have discovered that whales have different ‘accents’ or ‘cultures’ and the new study suggests that those differences are picked up when young through imitation of adults, in a similar way to how children learn to speak through copying. Writing in Proceedings of the Royal Society B, José Abramson of the Complutense University of Madrid, said: “Vocal imitation is a hallmark of human spoken language, which, along with other advanced cognitive skills, has fuelled the evolution of human culture. “We found that the subject made recognizable copies of all familiar and novel and human sounds tested and did so relatively quickly, most during the first 10 trials and three in the first attempt. “Our results lend support to the hypothesis that the vocal variants observed in natural populations of this species can be socially learned by imitation.” Whales are known to communicate over one hundred miles and have their own dialect and cultures  Credit: AP Photo/Miami Seaquarium In the wild, killer whales live in pods and each has its own dialect, which includes calls that are completely unique to themselves. Some clicks are even thought to represent names. But it was unclear where that knowledge came from. Previously killer whales have been observed mimicking the barks of sea lions and the whistles of sea dolphins and beluga whales have been filmed apparently imitating humans, but until now no controlled experiments have been carried out to verify the reports. In the new trial, Wikie was trained to understand a ‘copy’ signal then invited to repeat 11 completely new sounds given by her trainer. They included words and also noises such as an elephant call, a wolf howl and a creaking door. Wikie was given a fish or an affectionate pat when she achieved the sound to reinforce the learning. Six judges were then asked to rate whether the vocalisation matched the original word or noise. The researchers concluded: “In sum, Wikie made recognizable copies of the demonstrated sound judged in real time by two observers, Wikie’s trainer and one experimenter, later confirmed by both after listening to the recordings. “The subject’s matching accuracy is all the more remarkable as she was able to accomplish it in response to sounds presented in-air and not in-water, the species’ usual medium for acoustic communication. “It is conceivable that our data represent a conservative estimate of the killer whale’s capacity for vocal imitation.” The whale words were also analysed in waveform and matched the human words when the acoustical recordings were compared. Dr Alex Thornton, senior lecturer in cognitive evolution at the University of Exeter, said: “We still don't fully understand why some animals learn to mimic, but there are a few possibilities. “In some cases, mimicking might be deceptive. Fork-tailed drongos in the Kalahari, for instance, copy meerkat alarm calls so that the meerkats drop their food in alarm and the drongo can swoop in and steal it. “In other cases, copying sounds might be a way of showing off to potential mates. If a male is good at learning to make lots of different noises, females might use this as an indication that they are also good at learning to find food and feed offspring. “Finally, in some cases copying sounds might help to identify an individual as a member of a group. Some whales, for example, learn their calls from one another and so have local vocal dialects that mark them out as members of their social group.”
