Lab notes: Scientists develop tech to make antibiotics more effective, reduce drug resistance

A new nanotechnology system can help drug delivery especially in cancer patients prone to bacterial infections.

Scientists have developed a new antibiotic drug delivery system that improves the efficacy of the medicines. The new system developed using nanotechnology allows lower doses of antibiotics to be used against bacterial infections. This technology can help resist growing antibiotic resistance. It may also be particular use for cancer patients who are prone to bacterial infections.

The study by researchers at the Centre for Biomedical Engineering at the Indian Institute of Technology, Delhi demonstrated how conventional antibiotics are distributed imperfectly in the body due to poor water solubility, lack of target specificity and loss of efficacy. This is why pathogenic bacteria develop resistance to these drugs over a period of time. The research team used nano-particles to overcome these inefficiencies and to boost the delivery drugs at a cellular level. The nanotechnology has proved effective against the bacteria Escherichia coli and Salmonella typhi, according to the study published last month in journal Scientific Reports.

So far, doctors have combated resistance to certain common antibiotics by prescribing stronger antibiotics. In particular, cancer patients who undergo chemotherapy are prone to infections as their immune systems weaken. The new study aims to help reduce antibiotic dosages and the possibility of drug resistance setting in, co-author of the study Neetu Singh told The Hindu. With no major antibiotics being developed in the recent past, the research team felt that it was important to try and improve the efficacy of existing drugs by improving delivery and interaction with bacteria. They clarified that more studies need to be carried out before the technology can be tested on animals.

Not just for experts: How videography is poised for a disruption

Digital solutions are making sure it’s easier than ever to express your creativity in moving images.

Where was the last time you saw art? Chances are on a screen, either on your phone or your computer. Stunning photography and intricate doodles are a frequent occurrence in the social feeds of many. That’s the defining feature of art in the 21st century - it fits in your pocket, pretty much everyone’s pocket. It is no more dictated by just a few elite players - renowned artists, museum curators, art critics, art fair promoters and powerful gallery owners. The digital age is spawning creators who choose to be defined by their creativity more than their skills. The negligible incubation time of digital art has enabled experimentation at staggering levels. Just a few minutes of browsing on the online art community, DeviantArt, is enough to gauge the scope of what digital art can achieve.

Sure enough, in the 21st century, entire creative industries are getting democratised like never before. Take photography, for example. Digital photography enabled everyone to capture a memory, and then convert it into personalised artwork with a plethora of editing options. Apps like Instagram reduced the learning curve even further with its set of filters that could lend character to even unremarkable snaps. Prisma further helped to make photos look like paintings, shaving off several more steps in the editing process. Now, yet another industry is showing similar signs of disruption – videography.

Once burdened by unreliable film, bulky cameras and prohibitive production costs, videography is now accessible to anyone with a smartphone and a decent Internet bandwidth. A lay person casually using social media today has so many video types and platforms to choose from - looping Vine videos, staccato Musical.lys, GIFs, Instagram stories, YouTube channels and many more. Videos are indeed fast emerging as the next front of expression online, and so are the digital solutions to support video creation.

One such example is Vizmato, an app which enables anyone with a smartphone to create professional-looking videos minus the learning curve required to master heavy, desktop software. It makes it easy to shoot 720p or 1080p HD videos with a choice of more than 40 visual effects. This fuss- free app is essentially like three apps built into one - a camcorder with live effects, a feature-rich video editor and a video sharing platform.

With Vizmato, the creative process starts at the shooting stage itself as it enables live application of themes and effects. Choose from hip hop, noir, haunted, vintage and many more.

Or you can simply choose to unleash your creativity at the editing stage; the possibilities are endless. Vizmato simplifies the core editing process by making it easier to apply cuts and join and reverse clips so your video can flow exactly the way you envisioned. Once the video is edited, you can use a variety of interesting effects to give your video that extra edge.

You can even choose music and sound effects to go with your clip; there’s nothing like applause at the right moment, or a laugh track at the crack of the worst joke.

Or just annotated GIFs customised for each moment.

Vizmato is the latest offering from Global Delight, which builds cross-platform audio, video and photography applications. It is the Indian developer that created award-winning iPhone apps such as Camera Plus, Camera Plus Pro and the Boom series. Vizmato is an upgrade of its hugely popular app Game Your Video, one of the winners of the Macworld Best of Show 2012. The overhauled Vizmato, in essence, brings the Instagram functionality to videos. With instant themes, filters and effects at your disposal, you can feel like the director of a sci-fi film, horror movie or a romance drama, all within a single video clip. It even provides an in-built video-sharing platform, Popular, to which you can upload your creations and gain visibility and feedback.
