LONDON (Reuters) – Scientists have created hybrid embryos from the sperm of near-extinct northern white rhinoceroses in the laboratory, hoping they can ultimately help save the species. The northern white rhino is the world’s most endangered mammal, and its only two living members are a mother and daughter, living in Kenya’s Ol Pejeta Conservancy. Scientists
Mice on a ketogenic diet have shown remarkable responses to a class of cancer drug, which has previously experienced largely underwhelming results in human clinical trials. The study published today in Nature shows how a combination of a ketogenic diet with a type of cancer drug called a PI3K inhibitor, strongly improves the effect of
NASA / GSFC There is a large suite of scientific evidence that supports the picture of the expanding Universe and the Big Bang. The entire mass-energy of the Universe was released in an event lasting less than 10^-30 seconds in duration; the most energetic thing ever to occur in our Universe’s history. Looking out at
Find your passion, they say. As if it were easy. As if, just by looking around the place, you might stumble into what you love – a glimmering spark hidden, just out of sight, until that very moment. It doesn’t work that way, psychologists say in a new paper examining the basis of people’s interests.
For the first time, scientists have measured what actually happens with face-to-face interactions when employees start to work at an open-plan office – and their results show these modern workspaces are not as collaborative as you’d think. Two researchers from Harvard Business School and Harvard University wanted to empirically test whether removing walls at a

You are in a room. There is a marshmallow in front of you. An adult says if you don’t eat it, there’ll be more. The adult leaves. What do you do? This torturous predicament is the famous marshmallow test: an experiment designed by psychologists in the 1960s to gauge how successfully children can control their
News is out today that the entire genome of the koala has been sequenced. This means we now have a complete read-out of the genes and other DNA sequences of this iconic marsupial mammal. Knowing the full set of koala genes deepens our knowledge of koalas (and other Australian mammals) in many ways. Now we
The emergence of life on Earth was obviously a time of great change for our wee blue marble. Plants and algae had evolved some time before, helping convert the atmosphere from carbon dioxide to oxygen, which paved the way for fauna. But the change did not stop there: when animals did turn up around 520-540
If you’re looking for inspiration for your Fourth of July party, look no further than this incredible firework ladder that blazes its way into the sky.

It would be amazing and terrifying if true – a ‘laser AK-47’ that can set fire to targets and clothing from 800 metres (half a mile) away. According to South China Morning Post, that’s exactly what researchers at a Chinese company called ZKZM Laser have developed. The newspaper claims that the rifle beam cannot be
All the planets in the Solar System are more or less oriented the same as the Sun, with North and South pointed in the same direction. Not Uranus though. The blue planet’s north-south axis is tilted 98 degrees from the Sun’s orbital plane – it’s practically orbiting lying down. It’s so weird that there’s no
In one fell sip, Seattle on Sunday became the first major US city to ban drinking straws, an environmentally friendly move that leaders hope will spark a nationwide conversation about small, everyday changes that people can make to protect the planet.

A picture is worth a thousand words. Unfortunately, those words sometimes speak lies. A new analysis of almost 1,000 scientific papers has revealed a shocking number contained inappropriately duplicated images – and while many of these resulted from honest mistakes, about one in ten of the papers caught out ended up being retracted. That’s a
For the very first time, astronomers have captured an image of a baby planet as it carves a path through the disc of dust that surrounds its star, an orange dwarf 113.4 parsecs (370 light-years) away from Earth. The star is called PDS 70, and astronomers have long suspected the existence of the planet in
Stress is great. It makes us faster, stronger, more agile and our brains have better recall and flexibility. That’s why people are willing to put themselves in stressful work situations or engage in extreme sports. The problem is that uncontrolled, stress can leave us frozen to the spot and unable to think – something all
Although rocket launches can look effortless and even glamorous, launching things into space is a risky business. And occasionally, it all can go very, very wrong. A Japanese start-up company learnt this the hard way on June 30, when its rocket MOMO-2 spectacularly crashed back to Earth after spending only a few moments off the launch

Some may remember the deadly book of Aristotle that plays a vital part in the plot of Umberto Eco’s 1980 novel The Name of the Rose. Poisoned by a mad Benedictine monk, the book wreaks havoc in a 14th-century Italian monastery, killing all readers who happen to lick their fingers when turning the toxic pages.
According to an American study, people spend around 1.6 billion hours each year standing idly at the roadside, at the cost of US$2.6 billion to the American economy. With all this waiting around, it’s only natural to question whether pushing the “walk” button will help us get to our destination sooner. To answer this question,
Researchers from Montreal’s National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking.
