It’s the end of the road for Pa. Turnpike’s emergency call boxes | Pittsburgh Post-Gazette

About 1,000 emergency call boxes are being removed along the 550-mile road because their use has dropped dramatically due to cell phones

The bright yellow boxes, located about a mile apart on the 550-mile turnpike, were installed in 1988 to give motorists a way to call for help if they had an emergency. They connect directly to the turnpike’s Traffic Operations Center in Highspire, where dispatchers can send help..

Warm Antarctica Caves Show Signs of New Species, Study Says – The Daily Beast

Warm caves under Antarctica’s glaciers may be hiding previously undiscovered plant and animal species, scientists say. A new study led by Australian National University revealed an extensive network of warm caves around Mount Erebus, an active volcano in Antarctica. Soil samples taken from the caves turned up traces of DNA that could not be identified, lead researcher Ceridwen Fraser said early Friday. “The results from this study give us a tantalizing glimpse of what might live beneath the ice in Antarctica—there might even be new species of animals and plants,” Fraser said, according to Agence France-Presse.

Soil samples taken from caves around Mount Erebus revealed unrecognizable DNA.

Ancient Science: Mysterious Babylonian Tablet Could Hold Mathematical Secrets For Today’s Researchers

The tablet was discovered in the early 1900s but researchers have since puzzled over its function.The calculations may have been used for architectural calculations when building pyramids or other structures.

“The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.”
