Smashing of monster asteroid half a billion years ago thought to have caused mini ice age
An enormous dust cloud that swept through the ancient solar system sent Earth into a mini ice age that sparked an explosion in primitive life on the planet, scientists say.
The space dust was created when a monster asteroid was smashed to pieces in a violent collision somewhere between Mars and Jupiter nearly half a billion years ago.

Babies born by caesarean section have different gut bacteria to those delivered vaginally, the most comprehensive study to date on the baby microbiome has found.
The study showed that babies born vaginally pick up most of their initial dose of bacteria from their mother, while C-section babies have more bugs linked to hospital environments, including strains that demonstrate antimicrobial resistance. The findings could explain the higher prevalence of asthma, allergies and other immune conditions in babies born by caesarean.

It sounds like an improbable fiction: a virulent flu pandemic, source unknown, spreads across the world in 36 hours, killing up to 80 million people, sparking panic, destabilising national security and slicing chunks off the world’s economy.
But a group of prominent international experts has issued a stark warning: such a scenario is entirely plausible and efforts by governments to prepare for it are “grossly insufficient”.

Air pollution particles have been found on the foetal side of placentas, indicating that unborn babies are directly exposed to the black carbon produced by motor traffic and fuel burning.
The research is the first study to show the placental barrier can be penetrated by particles breathed in by the mother. It found thousands of the tiny particles per cubic millimetre of tissue in every placenta analysed.

Many moons ago in Tibet, the Second Buddha transformed a fierce nyen (a malevolent mountain demon) into a neri (the holiest protective warrior god) called Khawa Karpo, who took up residence in the sacred mountain bearing his name. Khawa Karpo is the tallest of the Meili mountain range, piercing the sky at 6,740 metres (22,112ft) above sea level. Local Tibetan communities believe that conquering Khawa Karpo is an act of sacrilege and would cause the deity to abandon his mountain home. Nevertheless, there have been several failed attempts by outsiders – the best known by an international team of 17, all of whom died in an avalanche during their ascent on 3 January 1991. After much local petitioning, in 2001 Beijing passed a law banning mountaineering there.
However, Khawa Karpo continues to be affronted more insidiously. Over the past two decades, the Mingyong glacier at the foot of the mountain has dramatically receded. Villagers blame disrespectful human behaviour, including an inadequacy of prayer, greater material greed and an increase in pollution from tourism. People have started to avoid eating garlic and onions, burning meat, breaking vows or fighting for fear of unleashing the wrath of the deity. Mingyong is one of the world’s fastest shrinking glaciers, but locals cannot believe it will die because their own existence is intertwined with it. Yet its disappearance is almost inevitable.

The “strange” anatomy of a family of giant marsupials that roamed eastern Australia and Tasmania for much of the past 25m years has been revealed in a new study.
Scientists had already figured out that palorchestids had tapir-like skulls and large “scimitar-like claws”, but little was known about the limbs of one of the “strangest marsupial lineages to have existed”, according to the paper published by a group of Australian researchers.

Unseeable and inescapable, black holes already rank among the more sinister phenomena out in the cosmos. So it may come as disconcerting news that the supermassive black hole at the centre of the Milky Way appears to be growing hungrier.
Astronomers monitoring the colossal object, called Sagittarius A*, found that in the past year it appears to have consumed nearby matter at an unprecedented rate.

There comes a time in a scientist’s life when the surest route to global fame involves a bevy of naked French postmen with thermometers taped to their testicles.
At least that is the case for Roger Mieusset, a fertility specialist at the University of Toulouse, whose unlikely studies have earned him one of the most coveted awards in academia: an Ig Nobel prize.

Scientists have found hundreds of perfectly preserved footprints, providing evidence that Neanderthals walked the Normandy coast in France.
The prints suggest a group of 10-13 individuals, mostly children and adolescents, were on the shoreline 80,000 years ago.

The Philippines has reported its first cases of African swine fever, becoming the latest country hit by the disease that has killed pigs from Slovakia to China, pushing up pork prices worldwide.
The virus is not harmful to humans but causes haemorrhagic fever in pigs that almost always ends in death. There is no antidote or vaccine and the only known method to prevent the disease from spreading is a mass cull of affected livestock.

The lander module from India’s moon mission has been located on the lunar surface, the day after it lost contact with the space station, and efforts are underway to try to establish contact with it, the head of the nation’s space agency said.
The cameras from the moon mission’s orbiter had located the lander, said K. Sivan, the chairman of the Indian Space and Research Organisation (ISRO) according to the Press Trust of India news agency. He added: “It must have been a hard landing.”

André Ollivro stepped carefully down the grassy banks of an estuary in the bay of Saint-Brieuc, Brittany, not far from his beachfront cabin. The pungent smell of rotting eggs wafting from decomposing seaweed made him stop and put on his gas mask. It was a strange sight in what is usually a tourist hotspot.
“You can’t be too careful,” said the 74-year-old former gas technician, who is leading the fight against what has come to be known as France’s coastal “killer slime”.

India’s attempt to land an unmanned craft on the moon’s uncharted south polar region appears to have gone awry, when communication with the landing vehicle was lost moments before touchdown.
“Communications from lander to ground station was lost,” said Kailasavadivoo Sivan, chairman of the Indian Space Research Organisation early on Saturday. Data was still being analysed, he told a room full of distraught scientists at the agency’s tracking centre in Bengaluru.

The Loch Ness monster could be a giant eel, according to a fishy new theory that will keep Highland tourists guessing.
In one of the biggest DNA studies of its kind, a team of scientists from New Zealand’s Otago University found the presence of about 3,000 species in the deep murky waters of the Scottish loch.

Plastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.
Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the bronze and iron ages, the current period may become known as the plastic age.

‘You oughta be in pictures,” goes the 1934 Rudy Vallée song. And, as of last week, pretty much anyone can be. The entry requirements for being a star fell dramatically thanks to the launch, in China, of a face-swapping app that can decant users into film and TV clips.
Zao, which has quickly become China’s most downloaded free app, fuses the face in the original clip with your features. All that is required is a single selfie and the man or woman in the street is transformed into a star of the mobile screen, if not quite the silver one. In other words, anyone who yearns to be part of Titanic or Game of Thrones, The Big Bang Theory or the latest J-Pop sensation can now bypass the audition and go straight to the limelight without all that pesky hard work, talent and dedication. A whole new generation of synthetic movie idols could be unleashed upon the world: a Humphrey Bogus, a Phony Curtis, a Fake Dunaway.

The European Space Agency has said it altered the trajectory of one of its observation satellites to avoid a collision with a craft operated by Elon Musk’s SpaceX.
“@ESA’s Aeolus Earth observation satellite fired its thrusters, moving it off a collision course with a @SpaceX satellite in their Starlink constellation,” the agency’s Twitter account said.

People who regularly consume soft drinks have a higher risk of an early death, researchers have found, with the trend seen for both sugared and artificially sweetened drinks.
While experts say the study cannot prove soft drinks are a driver of an increased risk of death, they say the work – which is the largest study of its kind – supports recent public health efforts to reduce consumption of soft drinks, such as the UK’s sugar tax.
