The current practical use of antibiotics to treat infection has created drug-resistant mutations in common bacteria. Amoxicillin and other types of commonly-used antibiotics–which work by affecting the DNA of microorganisms, thereby blocking their ability to multiply–have grown increasingly less effective in the last few decades as their use has become more widespread. In a recent […]

An MIT scientist claims he has achieved “one of the Holy Grails of science”: an artificial leaf that stands up to practical application. The device simulates photosynthesis to generate electricity using just sunlight and water — reputedly doing so 10 times more efficiently than a real leaf. Daniel Nocera acknowledged that his team’s output is […]

Harvard researchers believe firefighters could one day control and even extinguish fires using a gun that fires electricity. The project, funded by the Defense Advanced Research Projects Agency and the Department of Energy, investigated what’s said to be a 200-year-old observation that electricity can affect a flame’s shape, a point that hasn’t previously been the […]
If you look up in the sky, the only thing you usually see is some blue, a cloud here and there, and maybe a plane or a bird, but apart from that… nothing. However, it turns out that there’s quite an invisible world out there right above you! Check it out:
Professor Miklós Zrínyi of Semmelweiss University in Budapest, Hungary, has invented a magnetic gel which can be shaped in various forms and then moved using magnetism. Soft magnetic materials like this one could be used for artificial muscles in robots, or to replace rigid machine components, such as valves. Other teams are also working on […]
