Sometimes scientific discoveries are made in world-class laboratories, when brilliant scientists come together to prove a wonderful idea true with fresh experiments. And sometimes, the secrets of the universe are hidden under a pile of pigeon poop.
And so it happened that the first observation of the crackle of nascent energy left over from the ...read more

Blazing across the sky for mere milliseconds, fast radio bursts (FRBs) are among the newest and most puzzling astronomical phenomenon. They come from extreme distances and appear without any known rhyme or reason, making them almost impossible to study in detail.
But luckily, artificial intelligence is helping researchers learn about this mysterious occurrence. By usi ...read more

Ben Novak’s pigeons aren’t much to look at. Cosmetically, they’re not too different from the scavengers you’d see on any city street.
But dive down to the cellular level, and you’ll find something very unusual: they’ve been bred for easier ...read more

Life extension – using science to slow or halt human aging so that people live far longer than they do naturally – may one day be possible.
Big business is taking this possibility seriously. In 2013 Google founded a company called Calico to develop life extension methods, and Silicon Valley billionaires Jeff Bezos and Peter Thiel have invested in Unity Biotechnology, which has a market cap of US$700 million. Unity Biotechnology focu ...read more
A new study shows that low meat diets, like those followed by pescatarians and vegetarians, use far less water than meat-rich diets. (Credit: Seika Chujo/shutterstock)
The world’s freshwater is in short supply thanks in part to a ballooning global population that uses thousands of liters of water everyday to produce foodstuffs from oil and vegetables to meat, dairy and alcohol. Now researchers have discovered new evidence that a healthy diet, like those followed by pescatarians and veget ...read more
