At Karlsruhe Institute of Technology (KIT), physicist Professor Thomas Schimmel and his team have developed a single-atom transistor, the smallest transistor worldwide. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte. The single-atom transistor works at room temperature and consumes very little energy, which opens up entirely new perspectives for information technology. The transistor is presented in Advanced Materials.
Many natural products and drugs feature a so-called dicarbonyl motif -- in certain cases however their preparation poses a challange to organic chemists. In their most recent work, Nuno Maulide and his coworkers from the University of Vienna present a new route for these molecules. They use oxidized sulfur compounds even though sulfur is not included in the final product. The results are now published in the prestigious journal Science.
With a new groundbreaking technique, researchers from University of Copenhagen have managed to identify a protein that is responsible for cellular memory being transmitted when cells divide. The finding is crucial for understanding development from one cell to a whole body.
Nanyang Technological University, Singapore (NTU Singapore) scientists have discovered a plant-based food preservative that is more effective than artificial preservatives.
New work from Carnegie's Ethan Greenblatt and Allan Spradling reveals that the genetic factors underlying fragile X syndrome, and potentially from other autism-related disorders, stem from defects in the cell's ability to create unusually large protein structures. They found that mutations in the gene Fmr1 create problems in the and the reproductive system. They can lead to the most-common form of inherited autism, fragile X syndrome, as well as to premature ovarian failure.
Researchers from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences recently developed an emulsion interfacial polymerization approach to synthesize polymer particles with hydrophilic-hydrophobic heterostructured surfaces and two-dimensional Janus film actuators.
Discoveries by two HHMI investigators show how proteins that organize into liquid droplets inside cells make certain biological functions possible.
If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases. The results of the study have just been published in the prestigious scientific journal Molecular Cell.
Developed and tested at the University of Huddersfield, the compound, containing ruthenium, is attracted to the vulnerable cancer cells, whilst leaving healthy cells untouched.
3D printing by direct laser writing enables production of micro-meter-sized structures for many applications, from biomedicine to microelectronics to optical metamaterials. Researchers of Karlsruhe Institute of Technology (KIT) have now developed 3D inks that can be erased selectively. This allows specific degradation and reassembly of highly precise structures on the micrometer and nanometer scales. The new photoresists are presented in the journal Nature Communications.
