Humans Accidentally Created a Protective Bubble Around Earth

"A pair of NASA space probes have detected an artificial bubble around Earth that forms when radio communications from the ground interact with high-energy radiation particles in space, the agency announced this week. The bubble forms a protective barrier around Earth, shielding the planet from potentially dangerous space weather, like solar flares and other ejections from the sun.

Earth already has its own protective bubble, a magnetosphere stretched by powerful solar winds. The artificial bubble that NASA found is an accident, an unintended result of the interplay between human technology and nature. When humans want to communicate with submarines near the surface of the ocean, they use a type of radio communication known as very low frequency waves, or VLF, transmitted from stations on the ground. Some of the waves can stretch all the way out into Earth’s atmosphere and beyond, where they affect the movement of the radiation particles bouncing around in the region. Sometimes, the interaction between VLF and these particles creates a barrier that can be seen by spacecraft orbiting the planet."

State Adds Marion River Carry To Adirondack Forest Preserve

"The state has added the historic Marion River carry to the Forest Preserve, ending a long-running dispute over the ownership of 216 parcels of land near the hamlet of Raquette Lake.
The deal secures a five-hundred-yard trail used by paddlers portaging between Utowana Lake and the Marion River. The carry is an essential part of a canoe route between Blue Mountain Lake and Raquette Lake.
The Open Space Institute bought the 296-acre parcel in 2012 for $2 million and transferred it to the state this year at no cost to the state.
Before OSI stepped in, the Marion River property faced the possibility of development, which might have cut off public access. But the OSI acquisition also offered a solution to a legal dispute dating back to the 1800s."

How bad is drug pollution in the Hudson?

"Scientists are taking samples of the Hudson River this month to measure how much pharmaceutical pollution gets washed into the waterway during heavy rains and to pinpoint its source."

"Anti-depressants, blood pressure medicine, decongestants and other medicines have already been detected in the Hudson in preliminary samples. The latest round of testing is a larger sweep of the river at a time of the year when pollution overall is washing into the Hudson at a greater rate due to runoff and sewage overflows."
