Fiber

The brewing of beer produces great quantities of leftover grain, which often ends up being processed into cattle feed. Scientists have developed a new method of extracting the protein and fiber from that waste, however, for use by humans.

Nokia and Vodafone have tested a new broadband technology that delivers a blistering 100 gigabits per second (Gbps). Conducted using the kind of network seen in the last mile between an ISP and a user, it could eventually be rolled out commercially.

The embedding of fibers within 3D-printed objects can be used to add properties such as electrical conductivity or extra strength to those items. Now, a shape-changing print nozzle has been developed to vary the orientation of those fibers – as the printing is in process.

Antioxidants fight oxidation, which can spoil food and alcohol and harm cells in the body. Now, researchers have woven antioxidants into nanofiber mats, which release the vital compounds slowly and could be useful for food coverings or bandages.

Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.

When it comes to manmade fibers, they can typically either be strong or tough. A new material developed in part by Germany's University of Bayreuth, however, is claimed to be both.

​Metal fibers are strong, but can't be stretched very far. Rubber fibers are stretchy, but they're not very strong. Well, scientists have combined the selling points of both materials into one type of hybrid fiber. It could be used in applications such as soft robotics.

Organic cotton, hemp, bamboo and even recycled plastics are being transformed into clothing for eco-aware fashionistas. Australia's Nanollose is going an even greener route with a system that makes use of biomass waste from the coconut industry to create a plant-free fiber.​

​Kevlar may be in for some competition. Scientists at MIT have developed new polyethylene nanofibers that are both strong and tough, and that could someday be used in applications such as less-bulky body armor.

​It's no surprise to hear that many people who consume a typical Western diet don't get enough fiber. They could, of course, change their eating habits, but now they may not have to. Scientists have developed a new type of wheat that has 10 times the amount of fiber as its normal counterpart.

A new study shows that monkeys in captivity lose so much of the diversity of their natural gut microbes, that the bacteria in their digestive tracts starts resembling those of modern Western humans.

A new trans-Pacific submarine cable built by NEC with the backing of a consortium of telecom companies and Google came online Thursday. The FASTER cable connects the U.S. west coast with Japan via a six-fiber pair cable bringing 60 Terabits per second (Tbps) of bandwidth under the Pacific.
