Labeled "bird-friendly" but may accelerate tropical forest clearing
Blue-Crowned Motmot - one of the many bird species that depend on tropical forests in coffee farming regions

A coffee landscape in the Soconusco Region of Chiapas, Mexico. There is a distinct difference between the two coffee farms depicted. On the right slope of the photo is Finca Irlanda, a coffee farm that has been recently certified as "Bird-Friendly®" coffee, and also meets criteria for Eco-OK Certification. The farm on the left, Finca Hamburgo, clearly looks different (i.e. you can see rows of coffee under the sparse shade, in contrast to the dense shade in Finca Irlanda). This second farm DOES NOT meet the criteria of "Bird-Friendly®" coffee nor for Eco-OK Certification and thus shows our point that not all farms qualitatively classified as "shade-grown" will meet rigid certification guidelines.

While shade coffee is promoted as protecting tropical forests and birds, conservationists are split on whether it actually works. The December issue of Conservation Biology has the latest on the debate: one side says shade coffee can give farmers a reason to preserve tropical biodiversity while the other side fears it can actually encourage farmers to clear more forest.
Shade coffee is a traditional farming method of growing coffee bushes under a canopy of diverse trees, which helps protect the many bird species that depend on them.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
