European crop yields and changing climate

Changing climate trends since the late 1980s may partially explain stagnant crop yields in Europe, according to a study. Wheat and barley crop yields have stagnated since the early 1990s, coinciding with a warming growing season, but it is uncertain whether there may be a cause-and-effect relationship between the crop yields and climate.

Vast majority of scientists believe in engagement on public policy debates

February 15, 2015-Scientists say they are facing a challenging time and 87% believe that scientists should take an active role in public policy debates. In addition, a sizable share believes that engaging with the public and news media can advance the careers of scientists, according to a new survey by the Pew Research Center in collaboration with the American Association for the Advancement of Science (AAAS).

nanostructure fabrication using FIB-grown free-standing metallic wires with rapid thermal annealing

3D metallic nanostructures have attracted intensive attention recently. By fabricating nanowires with compositional or microstructural nonuniformity across the width direction of a wire, thermal annealing-induced shape modification has been explored to achieve a desired style out of the strain-induced out-of-plane shape manipulation of free-standing nanostructures. This study has been published on SCIENCE CHINA Physics, Mechanics & Astronomy, 2015, Issue 4.

Transcriptomics Identifies Genes & Signaling Pathways That May Regulate Neurodegeneration

Neuronal death is a normal feature of brain development but also a defining feature of neurodegenerative diseases when improperly regulated. Results of a detailed and comprehensive analysis of transcriptome expression alterations during neuronal death have been reported. A large number of genes previously not linked to neuronal death were identified in the study. Although further functional analyses are needed, some of these genes may be important players in the regulation of neuronal death and represent potential targets for the development of novel therapies.

'Stressed' young bees could be the cause of colony collapse

Colony Collapse Disorder (CCD) is a major threat to bee colonies around the world and affects their ability to perform vital human food crop pollination. It has been a cause of urgent concern for scientists and farmers around the world for at least a decade but a specific cause for the phenomenon has yet to be conclusively identified.
