Swiss researchers said Monday they had calculated the mathematical constant pi to a new world-record level of exactitude, hitting 62.8 trillion figures using a supercomputer. “The calculation took 108 days and nine hours” using a supercomputer, the Graubuenden University of Applied Sciences said in a statement. Its efforts were “almost twice as fast as the

The typical Australian will change careers five to seven times during their professional lifetime, by some estimates. And this is likely to increase as new technologies automate labor, production is moved abroad, and economic crises unfold.

Some types of bacteria are hardy enough to survive in the most inhospitable of conditions – and that includes concrete, as a new study proves. Not only can microbes survive in this dry, inhospitable building material, they can actually thrive there too. The research shows that bacteria could provide early warnings of moisture-induced alkali-silica reactions

If you’re wondering just how advanced artificial intelligence (AI) systems are getting, then know this: the US military is testing an experimental AI network tasked with identifying likely future events worthy of closer attention, and days before they occur. The series of tests are called the Global Information Dominance Experiments (GIDE), and they combine data from a huge

Despite their magnificent towering presence, giraffes have somehow managed to keep their social behavior largely under the scientific radar. As it now turns out, we humans have deeply misunderstood these huge animals. “It is baffling to me that such a large, iconic and charismatic African species has been understudied for so long,” said University of Bristol

Birds’ nests are snug little places: safe, warm, and lined with soft materials to keep the vulnerable babies comfortable and protected. For the tufted titmouse (Baeolophus bicolor) and its closest relatives, that material is often the fur of mammalian carnivores, which scientists had thought pillaged from dead animals, or opportunistically snagged when the animals shed.

Greenland’s ice sheet has experienced a “massive melting event” during a heatwave that has seen temperatures more than 10 degrees Celsius above seasonal norms, according to Danish researchers. Since Wednesday the ice sheet covering the vast Arctic territory, has melted by around 8 billion metric tons a day, twice its normal average rate during summer,
