Researchers from the University of Cambridge* have collaborated with 3D image analysis software company Lume VR Ltd** to create Virtual Reality (VR) software that allows scientists to ‘walk’ inside cells.
Dubbed vLUME, the software takes super-high-resolution microscope scans and transforms them into virtual 3D worlds. Scientists can then navigate these creations using a virtual reality headset and dive into the internal structures of a human cell.
The Google Street View-style solution can be used to study everything from individual proteins to entire cells, allowing scientists to see where things go wrong when they go wrong. The software also enables scientist to rewind biological processes by looking through recorded and visualized datasets. The hope is that this unprecedented insight into cells will lead to new treatments for diseases.
In addition, vLUME enables researchers to share their work with other collaborators, using built-in image and video recording features.
Speaking about the breakthrough, Steven Lee, a research team leader in Cambridge's department of chemistry, said: “Biology occurs in 3D, but up until now it has been difficult to interact with the data on a 2D computer screen in an intuitive and immersive way. It wasn't until we started seeing our data in virtual reality that everything clicked into place”.
The fundamental technology behind vLUME, super-resolution microscopy, was awarded the Nobel Prize for Chemistry in 2014***. It makes it possible to obtain images that have resolutions higher than those imposed by the diffraction limit, which is due to the diffraction of light. Until now though, there hasn’t been an intuitive way to visualise and analyse this data in three dimensions; that’s where vLUME comes in.
Viewing data in this way can stimulate new initiatives and ideas, as Anoushka Handa — a PhD student from Lee's group — discovered. She used vLUME to image an immune cell taken from her own blood. She then stood inside it de her own cell in virtual reality. “It's incredible — it gives you an entirely different perspective on your work,” she said.
More details about vLUME are published in the journal Nature Methods****.

Christmas is literally just around the corner and for many that will mean patronising a busy bar or two for Festive works drinks. An inevitable part of this annual ritual is queuing up and sometimes walking away with the wrong order.
Plastic is a super convenient material, there’s no denying that, which is why we’ve come to rely on it to make everything from containers to drinking straws and mobile phones to vacuum cleaners. But our (over) reliance on plastic isn’t without environmental costs.
Virtual Reality (VR) technology immerses a user inside a computer-generated experience, allowing them to see, hear and interact with amazing 3D worlds. But the extent to which people have been able to physically feel those worlds has, until now, been pretty limited.
Contact lenses are nothing new. In fact, people have been wearing them for hundreds of years to help correct their vision. These small, thin discs of transparent material are usually custom-shaped and carefully formed to ensure they perfectly fit a person’s cornea.
British Summer Time has just ended (did you remember to turn your clocks back?), which means we’re back to Greenwich Mean Time (GMT) until next March. The clocks going back also means we are edging ever closer to winter and if you’re a homeowner with a garden, you’ll know that the prep work you do now really matters before the colder weather hits.
Exploring unknown and hazardous environments always presents a challenge. Burning buildings, for example, are dangerous to navigate, but if there are people trapped inside, it’s a risk our brave rescue teams often have to take.
Scientists have created an artificial leaf that can mimic photosynthesis, allowing it to turn sunlight carbon dioxide and water into energy.
A significant proportion of young people do not know what a career in engineering entails, new research from EngineeringUK has revealed. It’s a reality that has “far-reaching implications”, according to the Royal Academy of Engineering.
If you’re a pet food manufacturer, what’s the best way to improve your products? By asking an innovative tech company to develop a smart pill that can be eaten by animals and which takes samples as it progresses through their bodies, of course.
Until now, it’s our fingers that have been the things that connect us with computers physically, whether we’re typing on our keyboards or swiping on our mobile devices.
Apps that keep track of what you eat and monitor your steps each day are two-a-penny – and that’s great because it encourages more and more of us to proactively look after our health.
How many times do you look at your smartphone on an average day? For many people, their smartphones are the first thing they reach for when they wake up and the last thing they put down at night.
