Home. 'Oleo Sponge' may be the key to cleaning up after oil spills. Log In - New York Times. 'Physics-defying' gravity hills are one of the strangest natural phenomena we've seen. Scattered across the world are a number of bewildering 'mystery spots' that appear to defy gravity - places where cars seem to drift uphill, and cyclists struggle to push themselves downhill.
There are reportedly dozens of gravity hills around the world, in the US, the UK, Australia, Brazil, and Italy, and they all have one thing in common - if you drive your car to the bottom of the hill and put it in neutral, it will proceed to roll back UP the slope. Hot ice. Cheap plastic film cools whatever it touches up to 10°C. If heat is not your thing, rejoice: A thin plastic sheet may soon provide some relief from the intense summer sun.
The film, made from transparent plastic embedded with tiny glass spheres, absorbs almost no visible light, yet pulls in heat from any surface it touches. Already, the new material, when combined with a mirrorlike silver film, has been shown to cool whatever it sits on by as much as 10°C. And because it can be made cheaply at high volumes, it could be used to passively cool buildings and electronics such as solar cells, which work more efficiently at lower temperatures. During the day most materials—concrete, asphalt, metals, and even people—absorb visible and near-infrared (IR) light from the sun.
That added energy excites molecules, which warm up and, over time, emit the energy back out as photons with longer wavelengths, typically in the midrange of the infrared spectrum. Here's what happens in your brain when you finish someone else's sentence. Neuroscientists think they've finally figured out what our brain is doing when we finish someone's sentence for them - and it goes against our current understanding of how memory and language interact.
Based on brain activity measurements, a team from the US has found evidence that our hippocampus - the area of the brain responsible for memory - is largely to blame for us trying to complete other people’s sentences. This suggests that our minds automatically try to fill in blanks in sentences based off of our memories of language and how the other person speaks, a finding that links memory and language together for the first time. "Language is something that has classically been viewed as evolving and occurring in the cortex, which is why we have language and rats don’t," said team member Robert Knight, from the University of California, Berkeley.

5 cool things Australian researchers have discovered. This article was written by our partners over at Swinburne University of Technology, and was originally published on their Tumblr.
We've reposted it with their permission. There's plenty to celebrate when it comes to Australian science - for a relatively small population, we've made some big contributions to the world, from wi-fi to the bionic ear. But this National Science Week, Swinburne University of Technology in Melbourne is looking back at some of their quirkier research. 1. Chew more, stress less A Swinburne study found that chewing sugar-free gum reduces anxiety by more than 17 percent during stressful situations. 2.
Swinburne researchers discovered that mystery radio signals detected at the Parkes telescope were caused by opening the door of a microwave oven.
