EU satellite research project tackles urban air quality from space
A three-year project led by the Commission with ten partners from Greece, Germany, Hungary and Italy has developed an innovative system for monitoring and managing urban air quality and the related health risks. Results of the “ICAROS NET” technique were presented today in Budapest. ICAROS uses satellite-borne sensors to monitor the concentration of harmful particles in the air, caused by heavy industry, traffic and household heating systems. Four pilot trials of the ICAROS NET system are under way in Athens, Milan, Munich and Budapest. It is the first time that ultra-fine pollution particles have been detected from space with such accuracy and precision. Early results from the Athens pilot project are encouraging, indicating that the system is as reliable as land-based alternatives but provides better environmental information, and that environmental policy initiatives, such as reducing sulphur in diesel and introducing fuel alternatives such as natural gas, are successful in reducing pollution levels.
European Research Commissioner Philippe Busquin said: “Fine airborne particles represent one of the biggest threats to human health from air pollution. If we are to improve environmental and health policy-making in the EU, we need precise and accurate air pollution data. Monitoring air pollution is a good illustration of what space technology can do for citizens and provides an additional argument to boost EU investments in space. This is particularly relevant in our initiative to build a European capacity for Global Monitoring for Environment and Security.”

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...
