In a first-of-its-kind study, a researchers found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. If bacteria evolved on Mars when water last flowed billions of years ago, they might still be living in Mars' subsurface.

Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.

Loading video... Credit: Northwestern University Northwestern University researchers are building social bonds with beams of light. For the first time ever, Northwestern engineers and neurobiologists have wirelessly programmed -- and then deprogrammed -- mice to socially interact with one another in real time. The advancement is thanks to a first-of-its-kind ultraminiature, wireless, battery-free and fully implantable device that uses light to activate neurons. This study is the first optogenet...

Life renewing processes — physical, spiritual, emotional and mental — have been lost by modern cultures. Nature’s response, Climate Change, seems harsh, but if we listen, learn and accept Indigenous relational leadership, our Earth based wisdom will be reawakened and we will once again flow with Nature.
