"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).

"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.

"This tiny, self-folding robot could one day be part of a large ant-like swarm"
Call it a misspent youth playing with Optimus Prime and Megatron toys if you want, but there's just something about transforming robots that always captures our imagination. Researchers at the University of California, San Diego, recently appealed to this part of our nature by developing a miniature, centimeter-scale self-folding robot, which can assemble itself from out of a flat sheet and then shimmy along the ground by vibrating. Oh, yes, and it's designed to work in a swarm, too.

The California Fresh Fruit Association (CFFA) today announced the speakers for their upcoming 82nd Annual Meeting, March 25-27, 2018, in Pebble Beach, California. This year's event will feature addresses by Dr. Henrik Christensen, the Qualcomm Chancellor's Chair of Robot Systems, and Mr. Bill Bishop, Chief Architect and Co-Founder of Brick Meets Click. Both speakers will deliver passionate messages about issues that are impacting the future of California agriculture and what our industry must do to be prepared.
"The Second Coming of Ultrasound"
In the last few years, ultrasound has reinvented itself in some weird new ways. Researchers are fitting people's heads with ultrasound-emitting helmets to treat tremors and Alzheimer's. Startups are designing swallowable capsules and ultrasonically vibrating enemas to shoot drugs into the bloodstream. One company is even using the shockwaves to heal wounds. Even more intriguing though, is the possibility of using ultrasound to remotely control genetically-engineered cells. That's what new research led by Peter Yingxiao Wang, a bioengineer at UC San Diego, promises to do.

"Designing Customizable Self-Folding Swarm Robots"
Researchers at the University California, San Diego, are taking the first steps towards robotics swarms that can be rapidly customized, self-assembled, and then self-deployed, without needing tedious human intervention at every step of the way. They're laser-cut from flat sheets, can fold themselves up, and then skitter away with only a minimum of human finger-lifting. The heterogeneous swarm idea is not a new one: Insects have been doing it for ages, and it's been very effective for them.

"Cancer Immunotherapy Channeled via Remote Control"
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.

"Cancer-fighting cells activated with ultrasound"
UC San Diego-led researchers have developed cancer-killing immune cells activated by ultrasound. Their work in cell cultures could lead to more precise cancer treatment with fewer side effects. Cells can be activated at up to 10 centimeters (nearly 4 inches), reaching deep with the body. The ultrasound method could be applied to other biological functions, either for research or clinical applications.

"How immune cells can be controlled to kill cancer"
By engineering cancer-killing T cells that can be manipulated noninvasively by remote control, researchers have added a potentially powerful feature to an already promising type of immunotherapy known as CAR T cell therapy. In their journal report, Prof. Wang and colleagues describe how they added new features to CAR T cell therapy in which the T cells carry modules that can be manipulated to produce gene and cell changes through remotely controlled and noninvasive ultrasound.

"You won't believe just how sensitive our sense of touch is"
Our sense of touch is so sensitive that we can feel the difference of just a single layer of molecules, researchers have found. We can easily tell the difference between a range of surfaces, from the roughest of sand paper to a soothing caress. We read eye charts to test our visual acuity before getting behind the wheel of a car. Newborns take simple audio tests to check that they can hear before they go home with their parents. But in comparison, our sense of touch has been a bit neglected. Recently, researchers in California put our tactile sense to the test.

"Researchers: 1% of All Websites May Have Been Breached"
Tens of millions of websites could be hacked each year, according to researchers in San Diego who have invented a new testing tool. The team at UC San Diego's Jacobs School of Engineering claimed that 1% of sites analyzed over an 18-month period by their new "Tripwire" tool were breached. This was true of all sites irrespective of the size or reach, meaning visitors to 10 of the top 1000 most visited websites on the internet could be at risk. "No one is above this -- companies or nation states -- it's going to happen; it's just a question of when," said Alex Snoeren, the paper's senior aut
"Researchers Made a Clever Tool to Detect Hacks Companies Haven't Told Users About"
It feels only natural that 2017 would be the year we experienced one of the worst security breaches of all time. The Equifax hack affected 145.5 million U.S. consumers, but what's really shady is that the credit report company suffered another breach months before the one they disclosed in September. And trying to keep users in the dark for the sake of optics isn't an uncommon move. It took Yahoo almost a year to inform the public that it wasn't just a billion user accounts that were compromised. It was all of them.

"Researchers' tool uncovers website breaches"
Researchers from the University of California San Diego (UCSD) designed a prototype system to determine if websites were hacked. They conducted their study and monitored over 2,300 sites from January 2015 to February 2017. In the end, the system detected 1 percent, or 19 sites, were compromised, "including what appears to be a plaintext password compromise at an Alexa top-500 site with more than 45 million active users." None of the sites disclosed the breach to their customers.
