Researchers from the Physics Department at the Universitat Autònoma de Barcelona (UAB), the Institut de Ciènca de Materials de Barcelona (ICMAB-CSIC), and the Universidad de Zaragoza have created a new ultra-light transparent magnetic material. Thanks to its properties, the new material could have interesting technological applications, such as creating new types of flat screens and magneto-optical memory devices for computers.
The researchers have obtained the new ultra-light magnets by combining silica aerogel (aerogels are extremely light solid materials, and are so porous that they’re made up of 99% air) with extremely fine magnetic particles composed of neodymium, iron and boron (Nd2Fe14B). These were orientated through a magnetic field during the synthesis. The new material retains the transparent and light properties of the aerogel, as well as the magnetic properties of the chemical composition. The magnets obtained by the researchers in the laboratory have a cylindrical shape about 1cm in diameter and several centimetres in length.
Until now, all aerogels with magnetic properties created in other laboratories were too “soft”, from a magnetic point of view, for storing information, and this closed all windows of opportunity on many technological applications. A weak external magnetic field could easily erase any information stored.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
