Superbug-killing coating "magnetically" draws in bacteria

Scientists at Singapore's Nanyang Technological University (NTU) have created a "magnetic-like" coating that traps and destroys 99 percent of the bacteria and fungi that it encounters. The antibacterial coating has been shown to be effective against superbugs like Staphylococcus aureus and is already being used in the manufacture of contact lenses. As well as finding numerous biomedical and household applications, the research could lead to new wound treatments and even be used to target bacterial infections inside the body without the use of conventional antibiotics.Read More

Mammoth fisheye lens from the 1970s sells for £100,000

It's getting rarer these days to find the kind of specialist shops that have so much stock from years gone by that they're more like a mini-museum than a retail outlet. Grays of Westminster is just such an emporium. Exclusively dealing in products spanning the whole history of the Nikon Corporation, the award-winning central London curiosity shop managed to generate a huge online buzz this week by announcing the sale of an exceptionally rare monster of a wide-angle Nikkor lens for an equally gargantuan price of £100,000 (US$162,312).Read More

New process could revolutionize electron microscopy

Researchers at the University of Sheffield have created what sounds impossible - even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.Read More

Dual Eyewear sunglasses provide bifocal lenses for reading bike computers

Attempting to read your watch or bike computer through sweat-fogged glasses while simultaneously keeping half a pupil on the road ahead can be difficult and dangerous. And those expensive electronics don't do you much good if you can't read them. That's why Dual Eyewear has created sunglasses equipped with magnifying lenses that make reading those small, grainy LCD screens a little easier. Read More

Hand-finished 8x macro lens sticks to your iPhone

Gizmag regulars will know we're partial to a bit of aspirational iPhone photographic lens-lust, even though I'm personally hesitant to splash out on an expensive lens kit that might be rendered obsolete come the next iPhone update. But this stick-on 8x magnification lens might just be low-tech and affordable enough to take the risk with.Read More

Anon ski goggles use magnetic lenses for easy swapping

The problem with the interchangeable lens systems commonly used in ski goggles is that they're tedious to work with. You have to slowly tear the frame from the original lens, line the grooves of the replacement lens up just right and then snap it back together section by section. Not only is this the type of thing you might need to get a table in the cafeteria for, it's the type of thing that could haunt you all day if you inadvertently put the lens in cockeyed. The Anon M1 goggles make switchable lenses easier and more seamless than they've ever been. Magna-Tech is a simple design upgrade that lets you remove your original lenses and snap the new ones in place within seconds. Read More
