Sick bats also employ 'social distancing' which prevents the outbreak of epidemics, study suggests
In a new study, researchers demonstrate that sick bats, just like ill humans, prefer to stay away from their communities, probably as a means for recovery, and possibly also as a measure for protecting others.

Cryptic sense of orientation of bats localized: the sixth sense of mammals lies in the eye
Mammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments now show that the cornea of the eyes is the location of such an important sense in migrating bats.

Cave deposits reveal Pleistocene permafrost thaw, absent predicted levels of CO2 release
Expanding the study of prehistoric permafrost thawing to North America, researchers found evidence in mineral deposits from caves in Canada that permafrost thawing took place as recently as 400,000 years ago, in temperatures not much warmer than today. But they did not find evidence the thawing caused the release of predicted levels of carbon dioxide stored in the frozen terrain.

Greenland caves: Time travel to a warm Arctic
An international team of scientists presents an analysis of sediments from a cave in northeast Greenland, that cover a time period between about 588,000 to 549,000 years ago. This interval was warmer and wetter than today, the cave deposits provide an outlook in a possible future warmer world due to climate change.

Last Ice Age: Precipitation caused maximum advance of Alpine Glaciers
Geologists unexpectedly found mineral deposits in former ice caves in the Austrian Alps dating back to the peak of the last ice age. These special calcite crystals demonstrate that intensive snowfall during the second half of the year triggered a massive glacier advance leading to the climax of the last ice age.

Metal whispering: Finding a better way to recover precious metals from electronic waste
With a bit of 'metal whispering,' engineers have developed technology capable of recovering pure and precious metals from the alloys in our old phones and other electrical waste. All it takes is the controlled application of oxygen and relatively low levels of heat.
