Freezing is one of the simplest methods of preserving food, biological tissue and other perishables, but the formation of ice crystals can damage cells. Now, researchers from Massachusetts General Hospital (MGH) have developed a new way to "supercool" water and similar solutions to keep them in a liquid form well below the usual freezing point...

The concept of an invisibility cloak sounds like pure science fiction, but hiding something from view is theoretically possible, and in some very-controlled cases it's experimentally possible too. Now, researchers have developed a new device that works in a completely different way to existing cloaking technology, neatly sidestepping some past issues and potentially helping to hide everyda
Tony Northrup is regularly asked by viewers how he is able to capture handheld shots at such slow shutter speeds. For example, it's not uncommon for him to shoot with a telephoto lens at shutter speeds as slow as 1/25 of a second. His shutter speeds are guided by the "rule of doubles," a rule he made up to replace the film-era reciprocal rule. With lenses and cameras featuring better image
When you need to shoot at higher ISOs, the tradeoff is that you often have an image with a lot of visual noise. This can simply reduce fine details, but it can also introduce false colors into your shots. In any case, it's unsightly and there are many ways you can reduce noise during post-processing. In a new video tutorial, Mads Peter Iversen shows off a specific technique for reducing noi
Using techniques borrowed from astronomy, biologists have developed a new microscopy technique that delivers extraordinary 3D video of cells moving around inside living tissue. It's a fascinating window into just how busy and complex life is at the cellular level...

Particularly when shooting RAW images, you need to perform sharpening to your photos during processing to bring out the best in the files. However, you often don't want to sharpen your entire image the same way. For example, you typically want to sharpen the in-focus portion of your image but not the background or the sky. There many methods for selective sharpening and Nathaniel Dodson of tu
In the latest video of his "Landscape Photography Journals" video series, photographer Dave Morrow extensively covers how he captures sharp images with perfect focus. It may seem obvious how to capture in-focus images, but there are techniques to help ensure that you capture a sharp photo every time and that your focus is always precise. Morrow is a landscape photographer, so his techniques won&#
If you know you don’t want to produce unicorn vomit (and I applaud you for that), you may have decided that your content will be “professional.” I was extremely preoccupied with “professional” when I started creating content 10 years ago. It was out of the question for me to reveal anything about my non-work personality. Read More...The post Attract Better Clients and Customers with the ‘Ch
Over at Photoshop Cafe, Colin Smith has produced a new tutorial all about sharpening your images. If you shoot RAW, you will need to process your images to bring out the best quality that your files have to offer. This includes sharpening. While JPEG images often come out of the camera with a good amount of fine detail, one of the advantages of shooting RAW is that you are able to customize how m
Stem cells have incredible potential for regenerative medicine, but getting hold of them in large enough numbers can be tricky. Amniotic fluid may be a plentiful source, and now scientists from Lund University in Sweden have developed a method and device that can collect the fluid during delivery of a baby by caesarean section, to safely harvest large amounts of stem cells...Continue Reading
