Now that Ebola is ravaging parts of West Africa, a nasty meme is once again rearing its ugly head — the suggestion that epidemics are “nature’s way” of dealing with overpopulation. But it’s an assertion that’s as false as it is dangerous. Here’s why.
searching for “Archean” on amazon is a trippy experience.

Is it bad when the kid who did this is smarter than the teacher?
I would pull my kid out of school if they were being taught this shit.
without being told the whole thing doesn’t have to add up to 10 this is really frustrating. with better phrasing it’s a pretty cool problem.
Mushrooms have an extraordinary ability to control the weather, scientists have learned.
By altering the moisture of the air around them, they whip up winds that blow away their spores and help them disperse.
Plants use a variety of methods to spread seeds, including gravity, forceful ejection, wind, water and animals. Mushrooms have long been thought of as passive seed spreaders, releasing their spores and then relying on air currents to carry them.
But new research has shown that mushrooms are able to disperse their spores over a wide area even when there is not a breath of wind - by creating their own weather.
Scientists in the US used high-speed filming techniques and mathematical modelling to show how oyster and Shitake mushrooms release water vapour that cools the air around them, creating convection currents. This in turn generates miniature winds that lift their spores into the air.

250 hikers have escaped to safety. 45 are still unaccounted for.
This is the science behind Mount Ontake’s violent eruption in Japan on Saturday morning. Unbelievably, many hikers survived, documenting their perspective of the pyroclastic flow and trekking out of the volcanic wasteland.
Some background on Mt. Ontake, the Japanese volcano whose current eruption has stranded hikers on the mountain.
Stromboli in the distance
The island in the far distance behind this photo is Stromboli, off the coast of the island of Sicily.
Stromboli is a very well constructed volcano, as testified to by the classic cone shape of the island, and peaks at a height of nearly 1000 meters above sea level. The volcano sits above the subduction zone that feeds many of the volcanoes in southern Italy and the islands in the Mediterranean Sea.
Stromboli sometimes acts as the lighthouse of the Mediterranean. It stands tall above the horizon and there is regularly a red glow from its summit. Although it pauses on occasion, this is one of the most active volcanoes in the world. It has literally been erupting almost non-stop for 2000 years.
This type of eruption, with small spurts of lava into the air, is even commonly referred to as Strombolian. Stromboli erupts small spurts of gas-rich magma; the gas forms bubble-rich blobs of magma several kilometers below the surface. These “blobs” of gas and magma are less dense than the surrounding rocks and are driven up to the surface where they create the typical small explosions and fling lava into the air.

This unique geological sight is known as Danxia landform. The Danxia landform refers to various landscapes found in southeast and southwest China that “consist of a red bed characterized by steep cliffs”. It is a unique type of petrographic geomorphology found in China.
Danxia landform is formed from red-colored sandstones and conglomerates of largely Cretaceous age. The landforms look very muchlike karst topography that forms in areas underlain by limestones, but since the rocks that form Danxia are sandstones and conglomerates, they have been called “pseudo-karst” landforms.
Danxia landforms cover several provinces in southeast China. Taining County, Fujian Province, has very good examples of “young” danxia landforms wherein deep, narrow valleys have been formed. As the landform gets older, valleys widen and one gets isolated towers and ridges.
