Researchers want to build a space station to recycle junk in Earth’s orbit
There are about 22,000 large objects orbiting the Earth, including working and broken satellites and bits of old rocket from past space expeditions. If you include all the equipment dropped by astronauts while floating in space and the debris from colliding satellites down to around 1cm in size, there are about one million bits of space junk in Earth’s orbit. дальше »

Research: Climate change helped elephants evolve a large brain
Elephants have long captivated our attention, partly because of their sheer size and majesty. But we’re also struck by their complex behavior. In some ways, we’re fascinated because this behavior echoes our most humane feelings. дальше »

Study: People behave better when they think they’re being watched
If there exists one moral code that can be shared and agreed by almost all cultures and religions, then it must be the concept of “never impose on others what you would not choose for yourself”. дальше »

Would your mobile phone be powerful enough to get you to the moon?
Many people who are old enough to have experienced the first moon landing will vividly remember what it was like watching Neil Armstrong utter his famous quote: “That’s one small step for a man, one giant leap for mankind. дальше »

Scientists discovered table salt on Jupiter’s moon, Europa
Europa, a frozen moon around Jupiter, is believed to be one of the most habitable worlds in the solar system. It was first imaged in detail by the Voyager 1 probe in 1979, revealing a surface almost devoid of large craters. дальше »

New analysis of ‘moonquakes’ indicates the moon isn’t dead
We tend to think of the moon as the archetypal “dead” world. Not only is there no life, almost all its volcanic activity died out billions of years ago. Even the youngest lunar lava is old enough to have become scarred by numerous impact craters that have been collected over the aeons as cosmic debris crashed into the ground. дальше »

Nuking asteroids could save the Earth — but we need to make it legal first
The schlocky 1998 Bruce Willis movie Armageddon was the highest grossing film of that year. The blockbuster saw a master oil driller (Willis) and an unlikely crew of misfits place a nuclear bomb inside a giant asteroid heading for Earth, blow it up – and save humanity. дальше »

How did the moon end up where it is?
Nearly 50 years since man first walked on the moon, the human race is once more pushing forward with attempts to land on the Earth’s satellite. This year alone, China has landed a robotic spacecraft on the far side of the moon, while India is close to landing a lunar vehicle, and Israel continues its mission to touch down on the surface, despite the crash of its recent venture. дальше »

Study: Biodegradable bags aren’t as biodegradable as you first thought
The idea of a “biodegradable” plastic suggests a material that would degrade to little or nothing over a period of time, posing less of a hazard to wildlife and the environment. This is the sort of claim often made by plastic manufacturers, yet recent research has revealed supposedly biodegradable plastic bags still intact after three years spent either at sea or buried underground. дальше »

Here’s how the Earth got so wet, according to scientists
Water is essential for life on Earth and is one of our most precious natural resources. But considering how our planet formed, it is quite surprising how much water we still have. The Earth aggregated from a cloud of gas and dust – a protoplanetary disk – and was incandescently hot for the first few million years. дальше »

Here’s why the crashed Israeli moon mission was still a tremendous contribution to science
It came so close. It even took a selfie. But with only a few kilometers left to descend, something went wrong and the spacecraft Beresheet veered out of control, taking one final photograph just before it hit the surface. дальше »

First black hole photo confirms Einstein’s theory of relativity
Black holes are long-time superstars of science fiction. But their Hollywood fame is a little strange given that no-one has ever actually seen one – at least, until now. If you needed to see to believe, then thank the Event Horizon Telescope (EHT), which has just produced the first ever direct image of a black hole. дальше »

Scarecrow drones keep birds away from crops without causing them harm
As drones have become more common and affordable, many animal-loving people have worried about their tendency to scare wildlife. Yet that problem may have a silver lining: drones might be used to scare animals away from crops, resolving conflicts with fright rather than lethal force. дальше »

Why designers create products that are never meant to be real
Humans are great at telling stories. We use them to teach our children, to learn about ourselves, and to plan paths to the future. Speculative fiction, imagining worlds that are not our own, is a great tool for considering the societal consequences of things that haven’t happened yet, sometimes on a grand scale. дальше »

How ideological bias in video game design changes our view of society
Civilization VI, a game I like, has a new expansion pack out. It’s a strategy game series I’ve been playing since 1994 or so, and every Civ is a kind of simulation of how the world works. That’s what this piece is about: simulating systems. дальше »

How old, once-unusable geometry ideas are now helping us apply big data to medicine
Your brain is made up of billions of neurons connected by trillions of synapses. And how they’re arranged gives rise to the brain’s functionality and to your personality. That’s why scientists in Switzerland recently produced the first-ever digital 3D brain cell atlas, a complete mapping of the brain of a mouse. дальше »

Scientists say flies don’t like zebra stripes
Zebras are famous for their contrasting black and white stripes – but until very recently no one really knew why they sport their unusual striped pattern. It’s a question that’s been discussed as far back as 150 years ago by great Victorian biologists like Charles Darwin and Alfred Russel Wallace. дальше »

Asteroid-powered volcanoes killed the dinosaurs, scientists say
It’s almost 40 years since scientists discovered what wiped out the dinosaurs: an asteroid hitting Earthnear modern-dayMexico. That was it, or so we thought. A paper published today in Science further supports an alternative hypothesis: that catastrophic events following the impact could have helped cause the end of the dinosaurs and many other forms of life. дальше »

Bug sake! Climate change is killing off insects
Climate change gets blamed for a lot of things these days: inundating small islands, fueling catastrophic fires, amping-up hurricanes and smashing Arctic sea ice. But a global review of insect research has found another casualty: 40% of insect species are declining and a third are endangered. дальше »

Here’s why icons are sexist
Icons, which may seem like a small part of the digital landscape, reveal larger issues of unconscious bias in tech and beyond. In many instances I can recall, ranging from company presentations to popular apps and websites, the main icons displayed were obviously representative of men. дальше »

How selfies help Indian women from Delhi’s outskirts claim their right to the city
Taking selfies and posting them on social media is often derided as a narcissistic, self-absorbed, and attention-seeking practice. Filters come in for particular disdain due to the role they play in reinforcing unattainable beauty standards, by making faces lighter, slimmer, and wider-eyed than is natural. дальше »

What the moon’s craters reveal about the Earth’s history
Most scientists believe the rate at which the moon and Earth have been bombarded by meteorites has remained constant for the past two to three billion years. Understanding the age of craters on the moon can help us better understand the age of our own planet because the Earth would have received similar numbers of impacts. дальше »

Scientists say orangutans can ‘talk’ about the past JUST LIKE US
The evolution of language converted a defenceless naked ape into a world-dominating force. It fundamentally transformed how humans transmit information and knowledge. A large and potent component of language is our ability to communicate about things that are not here, that happened in the past, or that will happen in the future. дальше »
