“The ground looks like it’s breathing in this Quebec forest,” wrote user Daniel Holland on twitter. According to the Forbes report, air is involved in this illusion, as strong wind plays a role in moving the trees and the topsoil. During a storm the ground becomes saturated with water, loosening the soil’s cohesion. As strong winds move the top of the tree, the force is transferred by the stem, acting as a lever, to the roots and the ground begins to move.
The wind caused the trees to sway, roots and all. In fact, the whole floor seems to rise and fall as if the earth itself was breathing. The phenomenon works best with spruce trees with their almost disc-shaped root system growing in the uppermost layers of the soil.
A snow roller is a rare meteorological phenomenon in which large snowballs are formed naturally as chunks of snow are blown along the ground by wind, picking up material along the way, in much the same way that the large snowballs used in snowmen are made. Unlike snowballs made by people, snow rollers are typically cylindrical in shape, and are often hollow since the inner layers, which are the first layers to form, are weak and thin compared to the outer layers and can easily be blown away, leaving what looks like a doughnut or Swiss roll.

Oregon is home to the towering Cascades, a range of mountains and active volcanoes. The Lost Lake likely formed about 3,000 years ago, when lava flowing from a volcanic vent blocked a river channel and created the lake. The lake bed begins to fill in the late fall, when the amount of rain coming in starts exceeding the ability of the lava tubes to drain off the water. But during the dry months, the lake vanishes and turns into meadow. The reason? Two hollow lava tubes at the bottom of the lake are constantly draining the lake dry, much like a bathtub left unplugged. It’s not entirely clear where the water goes, but it possibly seeps into the porous subsurface underground. There have been numerous attempts to plug the leak, those endeavors, however, would only result in the lake flooding.Continue reading “Oregon’s ‘Lost Lake’ disappearing through lava tubes”→
Living Light is a lamp which harvests its energy through the photosynthetic process of the plant. As the plant photosynthesizes, it releases organic compounds into a soil chamber below. The organic matter is broken down by bacteria fostered through a microbial fuel cell. When this happens, electrons are created and transported away from the soil. The electric current is passed along a wire and fed into a ring fitted with LEDs. These light up when a user touches the plant’s leaves.
Dutch designer Ermi van Oers and her team will start off with a small production in 2018. Plans are already in place with Rotterdam to illuminate a city park.
Crown shyness (also canopy disengagement) is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps. The phenomenon is most prevalent among trees of the same species, but also occurs between trees of different species. There exist many hypotheses as to why crown shyness is an adaptive behavior, and the most prominent theory, is that the gaps prevent the proliferation of invasive insects.
