Over 1,000 aspirants, including 62 from India, have been shortlisted for an ambitious private mission to send four men and women on a one-way trip to Mars in 2024 to establish a More »
You’ve probably heard of the coal seam gas fire that blazes uncontrollably beneath the now-abandoned town of Centralia in Pennsylvania, US – the town that the creepy video game and film Silent Hill was based on.
But, while it’s been disruptive, this fire has only been burning for the past 53 years – a relative blink of an eye when you consider that in Australia a similar blaze has been smouldering for an estimated 6,000 years, long before the country was settled by Europeans.
Visible only as some foul-smelling steam, the coal seam blaze is contained 30 metres below the surface of Mount Wingen (which means “fire” in the local Aboriginal language) or Burning Mountain, located in the state of New South Wales. And it’s officially the oldest fire on the planet, that
A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led by University of Arizona anthropologist David Raichlen, was published today in the Proceedings of the National Academy of Sciences.
The Lévy walk pattern appears to be ubiquitous in animals, similar to the golden ratio, phi, a mathematical ratio that
A new experiment conducted by optical physicists at the University of Glasgow in Scotland presents evidence that light pulses can be slowed down by manipulating their spatial structure.
The results of the study were posted online at arXiv.org before being published inScience, and suggest that
