Leornado da Vinci entwarf einst ein Brückenkonzept für das Goldene Horn. Es wäre die längste Brücke seiner Zeit gewesen. Forscher des MIT stellten sich nun die Frage: Hätte dieses Konstruktion wirklich funktioniert?
Researchers at the MIT and the Seoul National University explored quantum tunneling, a phenomenon often used in undergraduate chemistry courses to demonstrate one of the “spookinesses” of quantum mechanics. Their experimental approach is unique, and it has enormous ramifications for future efforts to interrogate molecular structure and dynamics, with the present application affording fundamental insights into the nature of tunneling-mediated phenomena.
Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more than 13 °C. It almost sounds like magic, but a new system designed by researchers at MIT and in Chile can do exactly that.
Cement production currently causes 8 % of global carbon emissions. If cement production were a country, it would be the world’s third-largest emitter. Now, MIT researchers have found a way to eliminate carbon emissions from cement production.
MIT engineers report that they have cooked up a material that is 10 times blacker than anything that has previously been described. The material is made from vertically aligned carbon nanotubes, or CNTs — microscopic filaments of carbon, like a fuzzy forest of tiny trees, that the team grew on a surface of chlorine-etched aluminum foil. The foil captures at least 99.995 % of any incoming light, making it the blackest material on record.
Aufbauend auf einem herkömmlichen Silizium-Prozess haben Wissenschaftler des MIT zusammen mit Analog Devices einen RISC-V-Mikroprozessor mit Feldeffekttransistoren aus Kohlenstoff-Nanoröhrchen entwickelt.
Identifying species among plants and animals has been a full-time occupation for some biologists, but the task is even more daunting for the myriad microbes that inhabit the planet. Now, MIT researchers have developed a simple measurement of gene flow that can define ecologically important populations among bacteria and archaea, including pinpointing populations associated with human diseases.
MIT scientists have found that an interplay between atmospheric winds and the ocean waters south of India has a major influence over the strength and timing of the South Asian monsoon. Their results may help researchers interpret ancient monsoon variations, predict future activity in the face of climate change.
