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.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
