Lake sediments may be key to predicting melting sea ice in Canadian Arctic
Sediment layers from a lake in the western Canadian Arctic may hold the key to predicting sea-ice loss and warming Arctic temperatures, new research finds.
Finger-like structures on Mars could be the result of ancient microbes
Finger-like rock structures on Mars could harbor potential evidence of past life on the Red Planet, according to new research. In 2007, NASA’s Spirit rover landed on Mars’ “Home Plate,” a flat 90-meter-long area within the Gusev crater. Since then, researchers have been trying to make sense of finger-like rock structures splayed across the landscape. The working hypothesis at the time was that these rocks started out as continuous layers but eroded into odd shapes by the touch of wind and sand over the years.
Magnetic fields help target buried mine waste for removal
Butte, Montana made national headlines last month after thousands of snow geese died in the toxic and acidic waters of the Berkeley Pit. The large, deep pool is the former site of a massive copper mine and is just one remnant of Butte’s extensive mining history. Over the past century and a half, heavy metals and acid from numerous local mines have seeped into the groundwater, forcing the city of Butte to rely on reservoirs for drinking water.

Older Mayan pyramid detected within Chichén Itzá
Scientists in Mexico have found evidence for a third and earlier—more purely Mayan—pyramid inside of the famous and iconic Pyramid of El Castillo at Chichén Itzá, in Yucatán. Using a non-destructive technique that employed hundred of electrodes deployed on the surface of the pyramid, the researchers also confirmed previous discoveries of a second pyramid, as well as their own 2014 discovery of a partially water-filled sinkhole beneath the pyramid.
