Zoos belonging to World Association of Zoos and Aquariums filmed allowing shocking mistreatment of elephants, dolphins, lions, bears, penguins and whalesDozens of examples of harrowing cruelty towards animals in zoos have been overlooked by the world’s top zoo organisation, animal welfare groups have alleged.Zoos belonging to the World Association of Zoos and Aquariums (Waza) have been filmed over the past five years making animals perform dangerous tricks, confining them to inadequate premises and beating them, contrary to Waza’s code of ethics, which demands the “highest standard of animal welfare”.Related: World's top zoo organisation accused of links to Taiji dolphin slaughter in Japan Continue reading...

Faced with unreliable screening, many women with a high lifetime risk of cancer opt for preventative surgery, just as Jolie did. But the timing can be crucialAs an A-list Hollywood film-maker, Jolie has few financial constraints on her medical care. Yet, the medical choice she was presented with and the trajectory of her treatment will be familiar to many women treated in NHS clinics. In Britain, those with at least two first-degree relatives who have had breast or ovarian cancer are eligible for genetic screening. Mutations in the BRCA1 and BRCA2 genes affect only about one in 500 women, but have a dramatic impact on the risk of developing ovarian cancer.Related: Angelina Jolie reveals she had ovaries removed after cancer scare Continue reading...

Scott Kelly and Mikhail Kornienko will spend a year together on the International Space Station and conduct research into the feasibility of a manned Mars missionTheir respective countries may be going through one of the worst periods of hostility since the end of the cold war, but this week an American astronaut and a Russian cosmonaut will fly up to the International Space Station to spend a year on board together.Despite the enmities of the cold war and the frigid relations of their governments today, scientists and astronauts from Nasa and its Russian equivalent, Roscosmos, have a fruitful and friendly history of recent cooperation. As the US government has cut space program funding, for instance, Nasa has turned to its Russian counterpart to assist with mission logistics such as sharing a launch pad. Continue reading...

Climate change is a moral challenge threatening the rights of the world’s poorest people and those who deny it are not using God’s gift of knowledge, says presiding bishop Katharine Jefferts SchoriThe highest ranking woman in the Anglican communion has said climate denial is a “blind” and immoral position which rejects God’s gift of knowledge.It’s hard work when you have a climate denier who will not see the reality of scientific truth.Related: World Council of Churches rules out fossil fuel investments Continue reading...

For the next month the telescope will be free for Guardian readers to remotely observe the moon, nebulae, constellations and other objects in the night skyThe Bradford Robotic Telescope sits more than a mile above sea level on the rim of an old volcano on Tenerife in the Canary Islands. The telescope, part of the Teide Observatory, captures stunning images of the night sky from one of the best sites for astronomy in the world.

Carnivorous amphibian Metoposaurus algarvensis grew to the size of a small car and dates back to the Late Triassic PeriodFossil hunters have found the remains of a giant carnivorous amphibian that patrolled ancient lakes and rivers at the dawn of the age of the dinosaurs.The salamander-like predator grew to the size of a small car and feasted on the fish that thrived in the waterways of the Late Triassic Period, more than 200m years ago.

Shortening of spring each year is due to the way Earth’s axis wobbles as it moves – but most of us won’t notice the difference in our lifetimeEvery year spring is getting shorter by about 30 seconds, according to researchers.This is mainly to do with how the Earth’s axis wobbles – very slowly – as it moves, or as LiveScience explains, “like a wobbling top, in a type of motion called precession”.

Geologist suggests extracting precious metals from human waste would keep harmful substances out of the ground – and recover valuable objectsFortunes could be saved from going down the drain by extracting gold and precious metals from human excrement, scientists suggest.Sewage sludge contains traces of gold, silver and platinum at levels that would be seen as commercially viable by traditional prospectors. “The gold we found was at the level of a minimal mineral deposit,” said Kathleen Smith, of the US Geological Survey.

Every now and then an eclipse comes around, and this time the northern Atlantic Faroe Islands and Arctic archipelago Svalbard were the only places where a total eclipse could be seen. Svalbard residents had clear skies for a perfect view as the moon passed over the sun, but in the Faroe Islands, cloudy weather marred the experience Continue reading...

A specially chartered plane left the northern Russian city of Murmansk on Friday and flew to the Arctic so its passengers could get an unobstructed view of the solar eclipse. The plane flew to an area where a total eclipse could be seen, while other parts of the world were only able to witness a partial eclipse Continue reading...

Astronomers and scientists joined tourists, commuters and schoolchildren to witness what was billed as the most impressive solar eclipse since 1999The sun also eclipses, to misquote Ernest Hemingway. After hours of near-despairing reports insisting the clouds were too thick, sky-gazers at Newquay in Cornwall – positioned to be among the first in the UK to glimpse a phenomenon that has thrilled and terrified human beings for millennia – excitedly reported a hazy nibble out of a misty pale orange ball was visible just before 8.30am – narrowly beaten by a much sharper image from Madrid.

A European Space Agency mini-satellite captures the moment the moon passes in front of the sun in Friday's solar eclipse. The ESA's sun-watching Proba-2 monitors turbulence on the sun's surface using ultraviolet wavelengths. As well as being seen from space, the partial eclipse was visible across Europe, Russia and parts of the Middle East, Asia and north Africa Continue reading...

A breathtaking solar eclipse was witnessed by millions of people across Europe this morning. But on the roof of the Guardian HQ in north London, the view was ... underwhelming. A typically cloudy haze had obscured the sun completely before the moon had a chance to eclipse it. Skywatchers had been advised not to look directly at the sun, but on the roof of the Guardian, there was no danger of burnt retinas Continue reading...

The solar eclipse is captured in timelapse video footage from across Europe on Friday. Despite grey skies in many parts of the UK and northern Europe, areas such as Bristol and Plymouth were cloudless enough for sky-gazers to catch a glimpse of the rare phenomenon. The Faroe Islands and Svalbard were briefly plunged into darkness as the only regions to experience a full eclipse Continue reading...

New technique works 100 times faster than conventional 3D printing and makes objects within minutes by simply lifting them out of a pool of resinScientists have created a Terminator 2-inspired 3D printer that lifts objects fully formed from a pool of goo in a matter of minutes.The technique, which could transform 3D printing, works up to 100 times faster than current methods and produces objects that are considerably stronger.

A new method of 3D printing demonstrates how detailed solids can be 'grown' out of a liquid bath. Researchers have come up with a 3D printing method that dwarfs conventional 3D print speeds, making it possible to convert 3D designs into parts in minutes instead of hours. The technology could be used to print soft elastic materials, ceramics, and biological materials like tissues Continue reading...
