Greenhouse of steel trees in Switzerland: a pavilion inspired by nature

Greenhouse of steel trees in Switzerland: a pavilion inspired by nature | Arboriculture | Scoop.it

Steel trees with sprawling branches support the glass roof of this greenhouse in Switzerland. Designed by Buehrer Wuest Architekten and located in a botanical garden outside the village of Grüningen, the greenhouse is used for growing subtropical plants such as banana and papaya.

The architects borrowed structural patterns found in nature, like the membranes of a leaf, to create the geometric structure of the roof. 

 

From the architects: 'The new pavilion at the botanical garden at Grueningen relates strongly to its context. The design was inspired by the surrounding forest, not the built environment. Both the formal vocabulary and the structural concept derive from nature. The pavilion is conceived to harmonize with and expand the forest. The geometry of the roof as surrounding membrane was determined by the position of the old and new trunks. The forest was augmented by four steel trees that form the primary structural system of the pavilion. At about five meters, the trunks branch toward the treetop, which forms the natural roof. A secondary glass construction, suspended from the steel branches, encloses the inner space of the greenhouse.'

The world’s oldest astronomers: Scientists use ancient trees to look back on the history of our local cosmos

The world’s oldest astronomers: Scientists use ancient trees to look back on the history of our local cosmos | Arboriculture | Scoop.it
Scientists in Japan use ancient trees to look back on the history of our local cosmos, and discover a mystery.

 

Since the invention of the telescope in the year 1608, mankind has collected information about our local cosmos. As it turns out, we’re not the only ones. Trees have been doing the same for millennia.

 

A group of physicists led by Nagoya University graduate student Fusa Miyake has begun using information stored in ancient Japanese cedars to gain the oldest firsthand accounts of the local universe. They have discovered, hidden within tree rings, clear evidence of some surprisingly high-energy events—possibly supernovae or solar flares—that occurred more than 1200 years ago.

 

On Japan’s Yakushima island, trees regularly live at least a thousand years, thriving under the tree equivalent of a low-carb diet in the form of a low-nutrition granite bedrock that encourages a slower pace of growth. Miyake and her team examined core samples from two trees on this small island. Back at Nagoya University, they studied the number and thickness of the tree’s rings not just to determine the age of the trees but also to gather information about the atmosphere they breathed.

 

When high-energy radiation from space enters Earth’s upper atmosphere, it interacts with naturally occurring atmospheric molecules to produce the isotope carbon-14. As trees are firmly plugged into the earth’s carbon cycle by photosynthesis, the carbon-14 ends up in each tree ring, creating an annual record etched into the flesh of the tree of the average carbon-14 level in Earth’s atmosphere.

 

Miyake and her colleagues had good reason to focus on the rings corresponding to 775 AD. A previous project called IntCal, which uses tree records of carbon-14 levels to calibrate carbon-14 dating, had seen a noticeable rise in carbon-14 levels toward the end of the 8th century.

The signal Miyake’s team found was far above anything seen in recent times, indicating that Earth had been bombarded by an extremely intense burst of radiation. The rings revealed that, over the course of one year, the atmospheric level of carbon-14 rose 1.2 percent: nearly 20 times the normal variation.

 

This massive flash of radiation could have been caused by a supernova; a gamma ray burst from a supremely rare galactic event such as a collision of two neutron stars; or a super solar flare at least 10 times the size of the largest observed flare.

 

Using their knowledge of earth sciences, biology and astronomy, Miyake’s team uncovered a smoking gun in a cosmological whodunit. Now all that remains is to identify who fired that gun.

Abel Farias's curator insight, December 2, 2013 5:38 PM

You can find history in any object. Whenever archeologists look for new fossils they are looking for a something that tells them a story. In this article they talk about how tree rings explain how the environment was during the life of the tree. I would use this article in Chemistry class during the Carbon Dating unit. It shows how recent day scientist used carbon dating to make a new discovery
