During a tweetstorm on Friday, Musk nonchalantly erased Tesla and SpaceX's Facebook accounts. The abrupt move came after a Twitter user urged him to delete his company's accounts from the world's most popular social media platform. It also appears that Musk has removed Tesla subsidiary Solar City's Facebook page unprompted.

Spotted off the coast of Vancouver Island on Canda's west coast, the 28-year-old mother was swimming with her new born calf and two other daughters, who are five and eight (stock image). The attacking male was swimming with his 46-year-old mother who was instrumental in this never-seen-before attack, scientists say. The male had grabbed the newborn infant and was dragging it away from its mother while the male's mother blocked the calf's mother from reaching her newborn. This is the first account of infanticide reported in killer whales and the only case committed jointly by an adult male and his mother outside of humans.

From Droitwich salt springs to Loch Lomond, a geography professor is using a millennium-old manuscript (right) to hunt the UK's ancient and mythical features (see left).  Andrew Evans has found 26 fantastical features documented in an ancient book called Wonders of Britain that was written by a monk between the 9th and 12th centuries. Many of these 'wonders' - which range from a lake with 60 islands on it to a shape-shifting burial mound - have been forgotten or only recorded in legends. Since then, Dr Evans has been travelling around the country using this manuscript to hunt down and locate these ancient features. Anglesey, the island situated off the north coast of Wales (inset), is home to four of the wonders described in the script.

At least half of the beached whales are estimated to be dead. Images of the animals (pictured) were captured by distressed locals who rushed to the scene to help. Leaarne Hollowood from Margaret River jumped out of bed to the scene when she heard about the whales on Friday morning. She described the scene as 'horrific' and said at first she thought they were all dead. When she got closer, she realised some of the whales were still alive.

Around 70,000 years ago, a small star known as Scholz's star (left) approached our solar system, sending comets and asteroids from the outer reaches of the solar system towards its centre. Astronomers from the Complutense University of Madrid and the University of Cambridge analysed nearly 340 objects with hyperbolic orbits found in the solar system. They believe that the trajectories of a number of distant space rocks, which originated in the Oort Cloud (bottom right) still bear the mark of this close encounter to this day. It is likely that our early ancestor saw this star, millennia ago, as a faint reddish light glowing overhead in the area around the Big Dipper - also known as The Plough (top right).

The origins of a 6-inch skeleton that was once thought to be the remains of an alien have been uncovered by scientists. A new DNA study of the bones shows the remains are in fact human and belonged to a baby girl who had dwarfism.  Nicknamed 'Ata', the incredible find made in 2003 in Atacama, Chile, has a long cone like skull and just ten ribs. Genetic tests at the University of California, San Francisco and Stanford University have proven beyond contention that the bones were that of a human female that died 40 years ago.

With a lifeless gaze, a dangling bioluminescent protrusion that juts from their face, and a gaping mouth filled with razor-sharp teeth, anglerfish may be among the best representations of the peculiarities thousands of feet beneath the surface. And, their mating habits are fittingly bizarre. Anglerfish engage in what’s known as sexual parasitism; the male latches onto the female and slowly fuses with her body until the two have formed a permanent pair, with the male supplying sperm to his mate while simultaneously receiving nutrients.

A new interactive map (pictured) developed at the University of Cincinnati reveals which parts of world have been hit hardest by climate change, as well as which will bear the brunt over the next 50 years. The map, called Climate Ex, allows users to view how global warming affects temperatures and rainfall in regions across the globe. Areas such as northern regions of North America and Russia have unsurprisingly been hard hit, but others, such as the tropics around the equator, have also seen big climactic changes due to a loss of rainfall, the map shows. Brown and white show regions most heavily hit by climactic changes while yellow shows moderate effect and green little effect. In the UK (bottom right), areas of eastern Scotland have been most affected by climate change, with the map showing that over the next 50 years parts of Wales and northeast England will see big changes to their climate. In the United States (top right), the country's west coast has seen the most significant rise in temperatures and loss of rainfall, with average yearly rainfall dropping significantly over the past half-century.

An interactive map shows the location of the doomed Tiangong-1 Chinese space station. Predictions of where it may land come from Aerospace, an organisation based in El Segundo, California. The Chinese space station is predicted to land in latitudes close to 43° north and 43° south and the public can track the satellite via the real-time map that provides data on altitude, latitude and longitude as well.

Peter Dunsby (main image), a cosmology professor from the University of Cape Town, published his 'discovery' on the Astronomers Telegram (bottom right), only to realise he'd made a blunder. This journey of discovery was cut short after the realisation that the object in question (inset, left) had been observed through a telescope by Galileo in 1609. The Astronomer's Telegram Twitter made fun of the mistake and issued a certificate to mark Dr Dunsby's discovery (top right).

Researchers found a column of hot volcanic ash known as a magma 'plume' beneath the park that stretches all the way from Mexico. Experts suggest the plume a could explain the source of the heat that drives so much of the park's surface activity, such as its world-famous bubbling springs. The news follows a spate of four mini-tremors in the area last week that raised fears Yellowstone's supervolcano is about to blow. The researchers analysed seismic activity around Yellowstone using data obtained by the USArray network, which has listening stations positioned across North America. Based on these readings, the team discovered a 45 by 34-mile channel (72x55km) where seismic waves are slower (red in inset).

Mark Zuckerberg has vowed to make Facebook a more secure platform after users were left outraged by the Cambridge Analytica scandal that unfolded this week. The Facebook boss says the firm will conduct an investigation of apps that had greater access to information prior to the more recent limitations, which were rolled out in 2014. Zuckerberg also promised tighter restrictions on what data developers can access, a tool to more prominently display the apps you’ve given permissions to, and bans for developers that don’t comply.
