An expanded "DNA alphabet" could carry more information than natural DNA, potentially coding for a much wider range of molecules and enabling a variety of powerful applications, from precise molecular probes and nanomachines to useful new life forms.
Wissenschaftler des INM - Leibniz Institut fuer Neue Materialien haben herausgefunden, dass sich bestimmte Nanopartikel zu Gruppen anordnen, als waeren sie Atome. Wie die Atome von Metallen oder Edelgasen bilden sie dabei je nach Anzahl ganz bestimmte Formen.
Mammalian cells can now do what an electronic calculator can: perform logical calculations. ETH-Zurich researchers have equipped cells with a complex genetic network that can do more than just one plus one.
Researchers at the Center for Nanophysics and Advanced Materials of the University of Maryland have developed a new type of hot electron bolometer a sensitive detector of infrared light, that can be used in a huge range of applications from detection of chemical and biochemical weapons from a distance and use in security imaging technologies such as airport body scanners, to chemical analysis in the laboratory and studying the structure of the universe through new telescopes.
Researchers are demonstrating that proteins found in nature, but that do not normally bind the flu, can be engineered to act as broad-spectrum antiviral agents against a variety of flu virus strains, including H1N1 pandemic influenza.
By using a laser microbeam technology called optical tweezers, UC Irvine and UCLA researchers have uncovered fundamental properties of a key molecular signaling system involved with development, cancer and cardiovascular disease.
A team of Case Western Reserve University engineers has designed and fabricated integrated amplifier circuits that operate under extreme temperatures - up to 600 degrees Celsius - a feat that was previously impossible.
Around 200 textile research professionals met at the end of May in St Gallen at the international Fiber Society Spring Conference to keep abreast of current trends in research and development in this field. The host organization was Empa, where intensive work is being carried out on fiber and textile innovations.
