"New Form of Nanorobots to Clear Blood of Toxins"
Scientists and engineers have been envisaging and developing 'machines' small enough to swim through blood and move in bodily tissues. The point of such projects is to produce the definitive nanorobot, a new form of medical device that may be able to target things such as dangerous chemicals, virus particles or even cancer cells. A new example of the nanobot has been documented in a recent Science Robotics paper. The robot gets around many of the problems after being accepted by human immune cells through a custom membrane that makes it appear like a benign cell.

"Membrane-coated gold "robots" designed to detoxify blood"
It's never a good thing when donated human blood -- or even the blood in our bodies -- is infected with bacteria. Scientists at the University of California San Diego, however, are developing a means of removing such blood-borne microbes using tiny ultrasound-powered robots. The base "nanorobots" are made of microscopic lengths of gold nanowire. Via the external application of ultrasound, they can be propelled through liquids including blood, causing them to get thoroughly mixed with it. These nanorobots were coated in a hybrid of platelet and red blood cell membranes.

"Bent bird feathers repair themselves when soaked in water"
Splashing around in water doesn't just get a bird clean - it can also repair broken feathers from the inside. Marc Meyers at the University of California, San Diego and his colleagues repeatedly bent vulture feathers nearly in half, soaked them in water, and let them dry out again to test how much a bath can repair a feather, and how that process works. They tested two different parts of the feather's spine: the calamus, which is the hollow base that sits under the skin, and the rachis, which is the rest of the feather's central shaft.

"Just Look at This Freakin' CGI Fur"
When you look at fur, the light has taken an extended journey before hitting your eye, bouncing around lots of fur fibers and their microscopic structures. You can imagine that it's quite difficult for filmmakers to render these structures in CGI. Researchers at the Universities of California in San Diego and Berkeley have devised an improvement over fur rendering that they think is both more efficient and more practical. It's ten times faster than previous methods, and incorporates a more realistic model of fur to create more realistic images.

"Computer-generated fur gets more realistic"
If you're not satisfied with the realism of computer-generated animals in movies and games, then you might be interested in the latest news out of the University of California San Diego. Working with colleagues from UC Berkeley, computer scientists there have developed a new method of rendering fur that's reportedly much more accurate than existing techniques. Currently, fur is simulated in the same manner as is human hair - the computer utilizes a model that follows a ray of light as it bounces from one fur fiber to another. The technique requires a lot of processing power,

"Watch: Rendering Realistic Fur"
Scientists in California get to work on the coolest things. Take, for instance, the challenge of making computer-generated creatures look more realistic for their role in computer-animated films, special effects and video games. Recently, at the SIGGRAPH Asia conference in Thailand, researchers from UC San Diego and UC Berkeley presented their method for dramatically improving the way computers simulate fur - specifically, the way light bounces within an animal's pelt.
"AI is making more realistic CG animal fur"
Creating realistic animal fur has always been a vexing problem for 3D animators because of the complex way the fibers interact with light. Now, thanks to our ubiquitous friend artificial intelligence, University of California researchers have found a way to do it better. "Our model generates much more accurate simulations and is 10 times faster than the state of the art," said lead author Ravi Ramamoorthi. The result could be that very soon, you'll see more believable (and no doubt cuter) furry critters in movies, TV and video games. A lot of fur rendering systems were designed for human hair

"A New Way to Recycle Batteries Uses Half the Energy"
A new recycling process could provide a way to restore lithium ion battery cathodes to "mint condition." What's better, this new process only uses half the energy of conventional recycling methods. The new process centers on a non-destructive approach to recycling cathode materials. In the recycling methods that are typically used today, cathodes are broken into their separate elements. This new method would preserve the cathode material. The work was led by University of California San Diego Professor Zheng Chen.

"CRISPR/Cas9 Fitted with Ultrasound-Powered Propeller"
A new system that transports gene-editing tools into cells may leave other such systems in its wake. The new system, developed by American and Danish scientists, uses an ultrasound-powered nanopropeller. Instead of blades, the nanopropeller has an asymmetrically shaped gold nanowire that it churns through the fluid mosaic of the cell's plasma membrane. Once inside the cell, the nanopropeller falls apart and frees its cargo: a gene-editing complex consisting of the CRISPR-associated protein 9 (Cas9) and a single-guide RNA (sgRNA).
"Will Humans Still Be Driving Cars in 2040?"
More and more experts feel that the advent of the autonomous vehicles will mean zero driver's licenses in the near future. Some are more optimistic than others, but Henrik Christensen, director for the UC San Diego Contextual Robotics Institute, is the most pessimistic of them all. According to Futurism, Christensen feels that the kids born today will never drive a car in their lives. That means that in the course of just 16 to 18 years, by 2040, that is, autonomous vehicles will no longer be weird to look at, but popular to ride in.

"Armpit transplants could make up less stinky"
Earlier in his career, Callewaert delved into the what of the human armpit, IDing the types of bacteria that give people sweet--or smelly--underarm smells. He used DNA analysis to figure out once and for all what makes an axillary microbiome--the world of tiny organisms that hangs out under all of our arms--stink. Now, the Belgium-born scientist has moved on to the how--and he thinks he's figured out a way not just to reduce armpit malodor, but to reverse the stinkiest pits for the long term. The solution, he says, is an armpit microbiome transfer.

"Simple, Energy-Efficient Recycling Process for Lithium-Ion Batteries"
A simple new recycling process restores old lithium battery cathodes to mint condition using half the energy of current processes. Unlike today's recycling methods, which break down cathodes into separate elements that have to be put together again, the new technique spits out compounds that are ready to go into a new battery. The method works on the lithium cobalt oxide batteries used in laptops and smartphones, and also on the complex lithium-nickel-manganese-cobalt batteries found in electric cars.

We're a long way from controlling our immune systems as easily as we might change the channels on our televisions, but a new remote-control system, in the hands of clinicians, could enable the narrowcasting of immunotherapies. For example, cancer immunotherapies could be "switched on" in solid tumors and "switched off" in healthy tissues. The new remote-control system, then, could avoid the toxicities associated with the broadcasting of cancer immunotherapy throughout the body.
