Researchers have made a chip-based device that can generate a laser signal with frequencies spaced in a comb-like fashion. Their work could be used in telecommunications applications and in chemical analysis.
Scientists have discovered the universal building blocks that cells use to form initial connections with the surrounding environment. These early adhesions have a consistent size of 100 nanometres, are made up of a cluster of around 50 integrin proteins and are the same even when the surrounding surface is hard or soft.
In October, an interdisciplinary group of scientists proposed forming a Unified Microbiome Initiative to explore the world of microorganisms that are central to life on Earth and yet largely remain a mystery. An article describes the tools scientists will need to understand how microbes interact with each other and with us.
For years, scientists have been pursuing ways to imitate a leaf's photosynthetic power to make hydrogen fuel from water and sunlight. In a new twist, a team has come up with another kind of device that mimics two of a leaf's processes to harness solar energy to purify water.
A method for guiding replacement cells to diseased vascular segments using nanoparticles. The scientists demonstrated in mice that the fresh cells actually exert their curative effect in these segments.
Researchers have now used 3D print technology to create a new type of transparent electrode, which takes the form of a grid made of gold or silver 'nanowalls' on a glass surface. The walls are so thin that they can hardly be seen with the naked eye.
Researchers have developed a new material composite derived from quantum dots. These lipoprotein nanoplatelets are rapidly taken up by cells and retain their fluorescence, making them particularly well-suited for imaging cells and understanding disease mechanisms.
