Hayabusa 2: Asteroid image shows touchdown marks

A new image from Japan's Hayabusa-2 spacecraft reveals a dark splodge where it touched down on the surface of an asteroid last week.

The discolouration could have been caused by grit being blown upwards by the spacecraft's thrusters, or by the bullet it fired into the ground, according to BBC.

The purpose of the touchdown on asteroid Ryugu was to collect samples of rock for eventual delivery to Earth.

Hayabusa-2 arrived at Ryugu in June 2018 after a 3.2 billion km journey    Japan probe touches down on asteroid

During sample collection, the spacecraft approached the 1km-wide asteroid with an instrument called the sampler horn.

On touchdown, a 5g "bullet" made of the metal tantalum was fired into the rocky surface at 300m/s.

Chimpanzees talk just like us: Scientists record primates using gestures in the same way people use words

Man's closest animal relative, chimps, communicate in a distinctly 'human-like' way, scientists have found.    

The primates use gestures that follow some of the same rules as basic human language, according to Daily Mail. 

One was Zipf's law of abbreviation, which says commonly used words tend to be shorter, and the other is Menzerath's law, which predicts that larger linguistic structures are made up of shorter parts - such as syllables within spoken words. 

Experts made the discovery after studying videos of wild chimps living in Uganda's Budongo Forest Reserve.

Like other great apes, chimpanzees lack the ability to speak but have previously been shown to use meaningful gestures to communicate with one another. 

Climate change: 'Future proofing' forests to protect orangutans

A study has identified key tree species that are resilient to climate change and support critically endangered apes.

Planting them could help future proof rainforests, which are a key habitat for orangutans, according to the International Union for Conservation of Nature – IUCN, according to BBC

Researchers surveyed 250 plants in Indonesia's Kutai National Park.

Over 1,000 orangutans are thought to inhabit the park, as well as other rare animals such as the Malayan sun bear.

Toothless species of dinosaur that lived 100 million years ago and fed on eggs is discovered

A small, chicken-sized dinosaur that lived 100 million years ago has been unearthed by scientists in Mongolia.

It had huge shell crushing jaws and probably fed on eggs, seeds and molluscs thanks to its powerful mouth muscles, overcoming the fact it had no teeth.

It has been named Gobiraptor minutus after the Gobi desert where it was dug up, according to Daily Mail.

Resembling a giant chicken, it was a member of the crested oviraptorosaurs that featured in Jurassic Park.

Pandas used to be meat-eaters!

Scientists say the ancestors of the bamboo-loving animals were carnivores and had a more varied diet, say scientists

Pandas exist on a diet of solely bamboo, but their ancestors enjoyed a more varied diet that once included meat. 

It is thought the black-and-white bears evolved into vegetarians slowly over thousands of years, according to Daily Mail.

The most likely explanation is that they undertook changes in habitat, where available food types varied.

It remains unknown what meat the ancient bears would have enjoyed.
