"Could the Future Be Powered by Salt? This Researcher Thinks It's Possible"
If battery innovation were a cocktail party, lithium ion would be the one sucking up all the oxygen in the room, telling too many jokes and barely letting anyone get a word in edge wise. But these lithium ion batteries aren't perfect, explains Shirley Meng, a nanoengineering professor at the University of California San Diego. They're expensive and require the use of cobalt, which can sometimes be a conflict mineral. Meng and colleagues recently started looking into the question of whether our infatuation with lithium ion might be overshadowing other more promising areas of battery research.

"University of California San Diego Researchers Develop 'Easy-to-Use' 3D Bioprinting Method for Living Blood Vessels"
Bioengineers from the University of California San Diego (UCSD) have developed a 3D bioprinting method that integrates natural materials which produce lifelike organ tissue models. The UCSD team used their method to create blood vessel networks capable of keeping a breast cancer tumor alive outside the body as well as a model of a vascularized human gut. The research, recently published in Advanced Healthcare Materials, aims to accelerate the production of human organ models to be studied for pharmaceutical drug screening.

"Robots and AI in the OR"
In the operating room, robots help guide surgical instruments to precise treatment locations. They can repeat the same movements over and over again without fatigue, or remain completely stationary for long periods of time. Robots go where traditional surgical tools can't, and perform tasks unimaginable without computer assistance, sophisticated algorithms and advanced motion control technology. They make the impossible possible. Researchers at UC San Diego, led by electrical and computer engineering professor Michael Yip, are developing algorithms to help guide and eventually automate surger
"The chemical search for better white light"
To make LEDs that produce more natural-looking light, scientists are developing new phosphors. These are inorganic compounds applied to the dome-shaped cap covering an LED that alter the light emitted, giving it a more pleasing hue. Efforts to discover new phosphors have nearly always occurred through painstaking, trial-and-error experiments--for example, by using exploratory crystal-growth methods and combinatorial chemistry. A new study led by UC San Diego's Joanna McKittrick and Shyue Ping Ong suggests that computational screening may one day put the kibosh on the lab-intensive approach.

"Super-water-repellent surfaces can generate energy"
Scientists knew that they could generate electricity by running salt water across an electrically charged surface. But they could never get the process to make enough energy to be useful. Now engineers have figured out a way to do that. Their trick: Make the water flow over that surface much more quickly. They achieved this by making the surface super water repellent.

"3D organ maps bring $14 million to UC San Diego's Kun Zhang"
UC San Diego bioengineering professor Kun Zhang has been awarded $14 million to build 3D digital maps of human organs, accurate to the single-cell level. The money comes in two grants from the National Institutes of Health. One grant for $8.7 million will fund work on a map of the entire human brain. The five-year-grant is from the NIH BRAIN Initiative. The other grant, for $5.3 million, is for mapping the lungs, kidneys, bladder and ureters. That four-year grant is part of a larger initiative called the Human Cell Atlas, which aims to "map the adult human body at the level of individual cells

"4 ways how hackers can access your web browsing history"
Scientists have discovered four new techniques to expose inteternet users' browsing histories, which could be used by hackers to learn which websites they have visited. The techniques fall into the category of "history sniffing" attachkes, a concept dating back to the early 2000s. However, the attacks demonstrated by the researchers from the University of California San Diego in the US can profile or 'fingerprint' a user's online activity in a matter of seconds, and work across recent versions of major web browsers.

"Popular browsers made to cough up browsing history"
Anonymous Coward, in commenting on a report from The Register about vulnerabilities that expose people's browsing histories, pithily sums up potential repercussions like so: Sweetheart, whats this 'saucyferrets.com' site I found in your browsing history? If you value your privacy and your ferret predilections, be advised that in August, security researchers from Stanford University and UC San Diego presented, during the 2018 USENIX Workshop on Offensive Technologies (WOOT), four new, privacy-demolishing attack methods to get at people's browsing histories.
"Old School 'Sniffing' Attackes Can Still Reveal Your Browsing History"
Most modern browsers--such as Chrome, Firefox, and Edge, and even browsers such as FuzzyFox and DeterFox (different, security-focused versions of Firefox)--have vulnerabilities that allow hosts of malicious websites to extract hundreds to thousands of URLs in a user's web history, per new research from the University of California San Diego. What's worse, the vulnerabilities are built into the way they structure links, meaning that major structural changes will have to take place in these browsers in order to protect user privacy. The only browser that was immune to the attacks was Tor

"50 ways to leave your lover, but four to sniff browser history"
"History sniffing" promises a nose full of dust or, you're talking about web browsers, a whiff of the websites you've visited. And that may be enough to compromise your privacy and expose data that allows miscreants to target you more effectively with tailored attacks. For example, a phishing gambit that attempts to simulate your bank login page has a better chance of success if it presents the web page for a bank where you actually have an account.

"New technology could better monitor blood pressure"
New technology that could help better monitor blood pressure is in the works. The National Institutes of Health has just released a photo of a wearable device that might soon help detect the pressure of blood flowing through your arteries. A blood pressure cuff is traditionally placed around the arm to measure your blood pressure at the doctor's office, or you may even have a finger checker at home, but this new patch is different. It was developed by a team at the University of California, San Diego.
"How injecting tiny sponges will relieve the pain and misery of rheumatoid arthritis"
Rheumatoid arthritis is a particularly painful form of the disease where the body produces antibodies to its own joints. But there is hope for sufferers. In the not-too distant future, the pain, stiffness and destruction of joints caused by the condition could be contained by an injection of, wait for it, nanosponges. These safely soak up and neutralise a range of proteins that cause inflammation in the joints, usually in the hands, feet and wrists. And and while the breakthrough won't cure the autoimmune disease, it will help manage the condition that affects 400,000 Britons.
"A Robotic Expert Answers All Of Our Questions About Driverless Cars"
I'm probably the world's worst driver. And it's not just that I'm bad at driving, I don't like driving. I think it's stressful and boring. So believe me when I say: I am counting the days down until level-5 autonomous cars hit the road. I want the kind of car where I say, "Cool. So, I can take a nap and binge-watch Arrested Development now?" and the car responds "Of course, sweetie!" and brews me a warm mug of cocoa. But while I'm probably overly excited about self-driving technology, plenty of others are frightened of our driverless future.
