Bacteria navigate on surfaces using a ‘sense of touch’

Many disease-causing bacteria such as Pseudomonas aeruginosa crawl on surfaces through a walk-like motility known as “twitching”. Nanometers-wide filaments called type IV pili are known to power twitching, but scientists ignore which sensory signals coordinate the microbes’ movements. Now, EPFL researchers have found that Pseudomonas bacteria use a mechanism similar to our sense of touch…

New insights into immune responses to malaria

Advanced technologies have been used to solve a long-standing mystery about why some people develop serious illness when they are infected with the malaria parasite, while others carry the infection asymptomatically. An international team used mass cytometry – an in-depth way of characterising individual cells – and machine learning to discover ‘immune signatures’ associated with…
