A group at the Open University, led by Professor Andy Lane, has taken the first systematic look at what large-scale, commodity farmers – not those mainly involved in organic growing - think about genetically-modified crops. We know how consumers, governments and the food industry regard GM, but this is the first proper look at the attitudes of the people who would use GM crops.
Lane and his colleagues found that both farmers who have been involved in GM crop trials and those who have not, regard GM as a simple extension of previous plant breeding techniques, such as those which have produced today’s established crop types. They regard GM crops as an innovation which they would assess on its merits. Their real interest is in how GM crops would work in practice and whether they can contribute to the profitability of their farms. The research suggests that these farmers do not think that GM raises any issues of principle, or that it is a matter of right or wrong.
Professor Lane said: “New technology such as GM is attractive to farmers. They want to produce high-quality food profitably and they want to farm in an environmentally sensitive way. GM may allow them to reconcile this conundrum by doing both of these things at once.”
A particular advantage of GM is its potential to allow farmers to grow crops with high yields while using less herbicide. This involves new management practices. Lane and his colleagues found that farmers who have been involved in the Farm-Scale Evaluations to assess GM in action have found GM crops feasible to grow.
The researchers also looked at how farmers learn about new developments such as GM. They found that most of the learning farmers do is informal, for example by experimentation or from their networks, which are made up from a wide range of people not necessarily just farmers. These networks can extend over long geographical distances.
Many farmers disapprove of past cuts in public funding for agricultural advisory services. It is now complicated and expensive for farmers to get good advice. They also feel that there is poor communication between farmers and people involved in agricultural policy, and between farmers and relevant scientific research.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
