The new film continues the story of that rebellion's instigator, an intelligent chimpanzee by the name of Caesar, but picks up his story after a manmade virus has devastated the human population. Amid the rubble of our civilisation, the apes are pitted against surviving pockets of Homo sapiens in a battle for mastery of the planet.

Prof de Waal calls the storyline "impressive", adding: "I'm not usually into action films like this one, but this held my attention.

"The apes are very humanised: They walk on two legs, they talk - somewhat - they shed tears. In real life, apes do a lot of crying and screaming, but they don't produce tears like we do."

However, other aspects of ape behaviour in the film, he says, are true to life.

"We know chimpanzees are aggressive and territorial - they wage war. The use of tools and weapons is also a possibility," he explains.

To quote a colleague in his field, he said: "If you gave guns to chimps, they would use them."

One of the world's great radio telescopes isn't hearing voices – for the first time another giant dish has picked up one of the mysterious "fast radio bursts" (FRBs) that have been puzzling astronomers at the Parkes Radio Telescope. The find confirms these bursts indeed come from outer space, but beyond that their source is still wide open.

Last year the astronomers reported four bursts picked up by the celebrated Australian telescope. As each FRB lasted around a millisecond there was no time to have other telescopes check the same location, and the fact that no other telescope had picked up anything similar raised the possibility that something local was interfering with the Parkes telescope.

Now, however The Astrophysical Journal reports that the 305m Arecibo Telescope has picked up a similar burst while searching for pulsars. The burst occurred in 2012, but not noticed at the time. "FRB 121102's brightness, duration, and the inferred event rate are all consistent with the properties of the previously detected Parkes bursts," the authors report.
