Nematodes, such as the stem nematode, and fungi, such as white rot, are particularly harmful for onion crops in the Netherlands: they cause rot. Soil samples are investigated to detect this; a labour-intensive and expensive operation. Together with the Laboratory for Nematology (University of Wageningen) the company Blgg has developed a molecular technique to detect the stem nematode and white rot in soil samples.
Agricultural laboratory Blgg will start using the new system in November 2005. The system quickly and accurately measures soil samples at the molecular level. In a series of comparative trials, the molecular test had a higher detection rate than the traditional microscopic investigation for both the stem nematode and onion white rot.
Each year thousands of soil samples are investigated for their suitability for onion crops. They are examined for the presence of the nematode Ditylenchus dipsaci (the stem nematode) and the fungus Sclerotium cepivorum (onion white rot). For years this has been done visually under the microscope; a specialised and labour-intensive process.

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...
