Using MicroED on small molecules Tue, 13 Nov 2018 10:15:00 +0000 Nanoparticles in Articles of Daily Use Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are being incorporated outside the United States into a variety of kitchen products known as food contact materials (FCMs). Among the nanosilver-infused FCMs now on the market overseas are spatulas, baby mugs, storage containers and cutting boards. Fri, 09 Nov 2018 17:07:00 +0000 A New Path through the Looking-Glass Exploring the mystery of the molecular handedness in nature, scientists have proposed a new experimental scheme to create custom-made mirror molecules for analysis. The technique can make ordinary molecules spin so fast that they lose their normal symmetry and shape and instead form mirrored versions of each other. Fri, 09 Nov 2018 16:48:00 +0000 Catalyzing CO2 Imagine a day when - rather than being spewed into the atmosphere - the gases coming from power plants and heavy industry are instead captured and fed into catalytic reactors that chemically transform greenhouse gases like carbon dioxide into industrial fuels or chemicals and that emit only oxygen. It's a future that Haotian Wang says may be closer than many realize. A new system to reduce CO2 Fri, 09 Nov 2018 06:47:00 +0000 Breakthrough in Understanding a "Superbug" In a study of proteins historic in its scope, researchers at Oregon State University have pushed closer both to a vaccine for gonorrhea and toward understanding why the bacteria that cause the disease are so good at fending off antimicrobial drugs.

But who could have imagined a bionic mushroom that produces electricity? It sounds like something straight out of Alice in Wonderland, but researchers have now generated mushrooms patterned with energy-producing bacteria and an electrode network. They report their results in the ACS journal Nano Letters. An artificial symbiosis Wed, 07 Nov 2018 17:45:00 +0000 Nanotechnology-Based Immunotherapy that Promotes Organ Transplant Acceptance Mount Sinai researchers have developed a novel type of immunotherapy based on innovative nanotechnology that induces long-term organ transplant acceptance in mice. Their study, published in Immunity, could transform patient care and help to overcome barriers that prevent successful long-term transplant outcomes. Wed, 07 Nov 2018 10:04:00 +0000 Regeneration in the Digestive Tract The human gut is teeming with billions of beneficial bacteria. Therapies that use antibiotics often destroy most of them. Whether and how the intestinal flora will subsequently recover has been investigated by a research team that included scientists from the MDC. The results have been published in the scientific journal Nature Microbiology. Tue, 06 Nov 2018 16:51:00 +0000 Trying to Understand Cells' Interior Design How do you imagine the interior of our cells? Often compared to tiny factories, cells found smart and sophisticated ways to organize their 'interior'. Most biological processes require cells to bring together their 'employees', such as proteins and nucleic acids (like DNA), at the right time. Tue, 06 Nov 2018 14:33:00 +0000 Coping with Errors in the Quantum Age Nowadays, quantum systems can be manipulated with extremely high, but not perfect precision. ETH physicists have now demonstrated how errors that occur during such operations can be monitored and corrected on the fly. Tue, 06 Nov 2018 12:32:00 +0000 Tying the Knot: New DNA Nanostructures Knots are indispensable tools for such human activities as sailing, fishing and rock climbing, (not to mention, tying shoes).  But tying a knot in a lacelike strand of DNA, measuring just billionths of a meter in length, requires patience and highly specialized expertise. Hao Yan, a researcher at ASU, is a practiced hand in this delicate and exotic field, operating at the crossroads of nanotechnology and fine art. Mon, 05 Nov 2018 15:06:00 +0000 Nanorobots Propel Through the Eye Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.

Fri, 02 Nov 2018 10:35:00 +0000 Electronic Highways on the Nanoscale For the first time, the targeted functionalization of carbon-based nanostructures allows the direct mapping of current paths, thereby paving the way for novel quantum devices. Computers are getting faster and increasingly powerful. However, at the same time computing requires noticeably more energy, which is almost completely converted to wasted heat. This is not only harmful to the environment, but also limits further miniaturization of electronic components and increase of clock rates. Ballistic Wires Fri, 02 Nov 2018 09:18:00 +0000 Atomic View of Nature's Amazing Molecular Machines at Work Researchers from the MPSD's Department of Atomically Resolved Dynamics at the Center for Free-Electron Laser Science, the Centre for Ultrafast Imaging (all in Hamburg), the University of Toronto in Canada and the ETH in Zurich, Switzerland, have developed a new method to watch biomolecules at work.

Wed, 31 Oct 2018 08:59:00 +0000 AI and NMR Spectroscopy Determine Atoms Configuration in Record Time Many drugs today are produced as powdered solids. But to fully understand how the active ingredients will behave once inside the body, scientists need to know their exact atomic-level structure. For instance, the way molecules are arranged inside a crystal has a direct impact on a compound's properties, such as its solubility. Researchers are therefore working hard to develop technologies that can easily identify the exact crystal structures of microcrystalline powders.
