"Living-dead" bacteria exist in limbo: biologically active but not proliferating. Buried in this zombie state, disease-causing bacteria could come back from the dead to re-infect patients. Researchers at EPFL have produced the first evidence of this strange phenomenon in tuberculosis, suggesting new avenues for treatment.
To overcome the problem of interference between wireless networks, a researcher has developed an algorithm that automatically selects the best frequency band according to the usage of neighboring networks.
Scientists have used a cutting-edge method to stimulate neurons with light. They have successfully recorded synaptic transmission between neurons in a live animal for the first time. Neurons, the cells of the nervous system, communicate by transmitting chemical signals to each other through junctions called synapses.
Could graphene turn light to electricity? Scientists have shown that graphene can convert a single photon into multiple electrons, showing much promise for future photovoltaic devices. Graphene is a material that has gathered tremendous popularity in recent years, due to its extraordinary strength and light weight.
EPFL scientists have developed an extremely sensitive device that can detect life forms by sensing the slightest motion. The chemistry-free system can be used to rapidly test antibiotics or even to search for life on other planets. Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology.
Sscientists have uncovered the unconventional way that the cholera bacterium stabs and kills other bacteria to steal their DNA, making it potentially more virulent. Cholera is caused when the bacterium Vibrio cholerae infects the small intestine. The disease is characterized by acute watery diarrhea resulting in severe dehydration.
