antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as "gram-negative." these bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells.
measuring brain activity with precision is essential to developing further understanding of diseases such as epilepsy and disorders that affect brain function and motor control. neural probes with high spatial resolution are needed for both recording and stimulating specific functional areas of the ...
central to understanding why bacteria become antibiotic resistant is knowing how bacteria respond to the drugs trying to kill them. in a new study, boston college researchers report that antibiotics disrupt the genetic defensive responses in lethal bacteria.
inhaling black carbon could boost some disease-causing bacteria’s resistance to antibiotics.

i recently heard about probiotic cleaners and thought, "come again?" i was obviously familiar with probiotics when it comes to gut health (cue that "activi-ahhhhh" song!) but never in terms of cleaning. upon further investigation, i learned that these products are marketed as being allergy-free, non...

graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the nanoelectronics of the future. while graphene, a one-dimensional carbon layer, is a conductive material, it can become a semiconductor in th...
copper has long been known for its ability to kill bacteria and other microbes.
last august, we reported on work out of the u.s. department of energy’s slac national accelerator laboratory and stanford university in which the nanomaterial molybdenum disulfide was used to kill 99.999 percent of bacteria in water within just 20 minutes—a process that would otherwise take up t...
conventional wisdom has it that within virus-bacteria population dynamics, viruses frequently kill their host bacterial cells—a process called lysis—especially when there's a large concentration of bacteria. a different dynamic called lysogeny, in which viruses lie dormant within their host cell...
researchers and students in the graphene flagship are preparing for two exciting experiments in collaboration with the european space agency (esa) to test the viability of graphene for space applications. both experiments will launch between 6-17th november 2017, testing graphene in zero-gravity con...
with antibiotic resistance on the rise, bacterial contamination of food is becoming more problematic. now in a study appearing in acs biomaterials science & engineering, scientists report that they have developed an antibacterial "sugar-glass" coating in which viruses that destroy bacteria are embed...
researchers have uncovered how a virus uses a two-pronged attack against a single protein to kill bacteria.
scientists at the u.s. department of energy's ames laboratory were able to successfully manipulate the electronic structure of graphene, which may enable the fabrication of graphene transistors— faster and more reliable than existing silicon-based transistors.
on show for the first time at the gsma mobile world congress are two graphene based photonics devices which give a glimpse into the future of data communications. at the graphene pavilion, experience the world's first all-graphene optical communication link operating at a data rate of 25 gb/s per ch...
due to its distinctive properties graphene has been held out as a game-changing material for a range of industries and applications. the graphene flagship initiative was set up as europe's biggest ever multi-stakeholder research initiative, to quite literally shape the future of the technology.

thanks to its conductivity, strength and flexibility, graphene is considered as one of the most likely substitutes for silicon and other materials. however, it has not yet resulted in industrial applications. high-quality single-crystal graphene can only be produced in quantities a couple of millime...
