Now, researchers have revealed that colistin punches holes in bacteria, causing them to pop like balloons. The work, funded by the Medical Research Council and Wellcome Trust, and published in the journal eLife, also identified a way of making the antibiotic more effective at killing bacteria.

Scientists have revealed how an antibiotic of ‘last resort’ kills bacteria.

The findings, from Imperial College London and the University of Texas, may also reveal a potential way to make the antibiotic more powerful.

The antibiotic colistin has become a last resort treatment for infections caused by some of the world’s nastiest superbugs. However, despite being discovered over 70 years ago, the process by which this antibiotic kills bacteria has, until now, been something of a mystery.

The Virgin Galactic spaceship, VSS Imagine has been unveiled, revealing a more modular spacecraft designed to resolve challenges.

“For us to make the business start to scale, at the places that we’re aspiring towards, we need two things,” says Virgin Galactic CEO Michael Colglazier. “We need many more ships than we have right now and we also need the ships that we bring forward to be built in a way that they’re able to be maintained in a way that we can have much quicker than what we have with Unity.” In order to achieve those two elements of success, Virgin Atlantic has unveiled their latest spacecraft, the VSS Imagine. The new addition to the fleet is the third spacecraft built by Virgin Galactic and “has been designed in a way that’s taken the learnings we’ve had from all the flight testing on Unity.”

Tesla explained how it pivoted to avoid the global microchip shortage that Intel now says could last for several more years.

The pandemic has resulted in an increase in demand for many electronics and computers that the supply chain couldn’t handle, especially the semiconductor industry.

This microchip shortage, in turn, affected the automotive industry, which has increasingly become a big consumer of microchips.
