Trees twitter current trim – European science network facilitates real-time reports


Science-society event and press conference in and around Berlin

Forest on-line: European researchers enable trees to report real-time on how the changing climate is affecting them. Now vaporisation, water flows through the trees trunk and even the smallest growth increases of the tree are directly traceable on the internet.

It is new knowledge which the "Twittering Trees" deliver to the researchers of the European COST network "STReESS". How do individual trees and consequently forests respond to increasing stress by heat and dryness? Events likely to increase in the course of the climate change.

This detailed diagnosis of growth increases as well as changes in the water household of the trees allows recognising states of stress quickly. Growth and mortality reaction can appear spontaneously, but also be belated by weeks or months or even years.

However, the mortality risk can be identified by the short- and long-term growth patterns – an information with early warning potential.

Continuous extension of the "Twittering Tree" network could open up the possibility for a European-wide early warning system making the dangers of extreme weather conditions immediately recognizable. The EU-project has made a first step in this direction.

The “Twittering Trees“ and many other exciting results of European-wide studies on the effect of extreme weather conditions on forests are presented in the afternoon of Thursday, 14th of April, 2016, in an interactive science-society event featuring the motto "shaping future forests" in Joachimsthal near Berlin.

Journalists are kindly invited. For transportation a shuttle bus from Berlin to Joachimsthal is planned. If required please contact the Thünen Institute of Forest Ecosystems in Eberswalde (E-mail:, Phone: +49 (0) 3334 3820-339).

A press conference takes place on Friday 15th of April, 2016, from 10 to 11am in the Bundespresseamt Berlin.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
