IFDC — an International Center for Soil Fertility and Agricultural Development — has developed an innovative approach to agricultural development called Integrated Soil Fertility Management (ISFM), involving not just farmers, researchers, and extension workers but also bankers and traders, including inputs dealers and fertilizer enterprises. The holistic approach, based on the agribusiness system at the regional level, combines participatory methods to develop and extend ISFM technologies and support institutional changes that enable their adoption and facilitate effective linkages between farmers and the "market."
The primary donors for this work are the U. S. Agency for International Development (USAID) and the International Fertilizer Industry Association (IFA). Another project sponsored by the International Fund for Agricultural Development (IFAD) enhances the ISFM work.
"ISFM-based intensification technologies are based on the combined use of soil amendments and chemical fertilizers," says Dr. Arno Maatman, Leader, IFDC Input Accessibility Program. "Different amendments exist, and their requirement depends on soil characteristics. Organic resources are used for improved soil organic matter status. Limestone can be used to improve the pH level; soluble sources of phosphorus and phosphate rock are frequently used to increase the availability of phosphorus. The more difficult challenge is to improve the status of soil organic matter. More and better organic matter is needed. ISFM technologies that integrate the use of inorganic fertilizers with crop residue recycling, (green) manure, fodder crops, mixed cropping, crop rotation and agroforestry can improve the availability and quality of organic matter. The technologies lead in time to improved fertilizer use efficiency."

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
