"Toxin-absorbing nanosponges could be used to soak up localized infections"
Back in 2013, we heard that nanoengineers at the University of California, San Diago (UC San Diego) had successfully used nanosponges to soak up toxins in the bloodstream. Fast-forward two years and the team is back with more nanospongey goodness, now using hydrogel to keep the tiny fellas in place, allowing them to tackle infections such as MRSA, without the need for antibiotics.

"Imposter Nanosponges Fight Antibiotic-Resistant Infection"
Ever since the emergence of Methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that shows resistance to our strongest antibiotics, the race has been on to outwit this deadly organism. Now, a team of scientists think they might have found an ingenious solution: cunningly disguised nanosponges. The team have created a gel with bacteria-fighting nanosponges mixed in that can be applied to infected wounds. They tested the effects of the mixture on mice with skin lesions caused by MRSA.
"How much life is left in Moore's Law?"
Your new smartphone has more computing power than the fancy laptop you bought just two years ago because the electronics industry keeps marching down the path of Moore's Law. Even non-techies have probably heard of it. First observed by Intel co-founder Gordon Moore in a 1965 research paper, Moore's Law observes that chipmakers get the biggest bang for the buck when the number of transistors on semiconductors doubles every two years -- driving better performance, lower cost and improved energy

"Larry Smarr is the poster boy for wearable devices and the quantified self"
From the instant he wakes up each morning, through his workday and into the night, the essence of Larry Smarr is captured by a series of numbers: a resting heart rate of 40 beats per minute, a blood pressure of 130/70, a stress level of 2 per cent, 87kg, 8000 steps taken, 15 floors climbed, 8 hours of sleep. Smarr, an astrophysicist and computer scientist, could be the world's most self-measured man.

USD, UCSD, San Diego State Students Awarded $75,000 in Live Social Innovation Challenge. A proposal for an off-grid water purification system to sustain small communities with drinking water during disasters and emergencies was the big winner in the University of San Diego's fifth annual Social Innovation Challenge.
"The cyborg approach to spotting mines at sea"
Researchers have built a brain-computer interface designed to speed identification of mines in sonar images of the ocean floor. Computer scientists from the University of California, San Diego, worked with the Navy's Space and Naval Warfare Systems Center Pacific and collected 450 sonar images containing 150 inert, bright-orange mines in a test zone. Working with a dataset of 975 images of mine-like objects, researchers trained the algorithm to flag images that most likely included mines.

"UC students' big ideas wow judges with big money on line"
Alex Phan, a mechanical and aerospace engineering graduate student at University of California, San Diego, reacts as he is announced as the third place winner during the inaugural UC Grad Slam at Oakland Marriott City Center in Oakland, Calif. on Monday, May 4, 2015. On Monday in downtown Oakland, 10 University of California graduate students competed to see who could untangle their knotty investigations in the clearest way for just plain folks. Each had three minutes to explain.

"The Skinny On Skin"
Skin has to be flexible enough to jump, crawl, and kick with us. It also has to be resilient enough to withstand our falls, scrapes, and cuts. Scientists have marveled at skin's strength for years without knowing why it's so durable. Now, scientists have identified the mechanical properties that give skin its toughness. Their findings are the first to show that collagen, the most abundant protein in skin, moves to absorb stress and prevent the skin from tearing.
"Noted UCSD engineer dies at 84"
William S.C. Chang, a retired researcher who helped UC San Diego evolve into a major power in engineering by recruiting talented figures in semicoductors, integrated circuits, and wireless communications, died on April 25 at age 84. Chang passed away in La Jolla of undisclosed causes, the university said. Family members said Chang was born in Nantung, near Shanghai, China on April 4, 1931.
"Detecting sea mines gets faster"
UC San Diego says it may have found a faster way to detect sea mines, a type of explosive that poses a threat to American warships, especially those operating in the Persian Gulf. Researchers wrote computer vision algorithms that made it easier to detect mine-like objects that were contained in sonar images of inert mines that had been placed in San Diego Bay. The six people who were asked to review the images as part of the study displayed an improved ability to find the mines
"Robots Podcast: bStem, with Todd Hylton"
In this episode, Audrow Nash interviews Todd Hylton, Senior Vice President at Brain Corporation, about neuromorphic computers. They discuss the robotics development board bStem, which approximates a neuromorphic computer, as well as the eyeRover: a small balancing robot that demonstrates how the bStem can be used in mobile robots.
"Aerospace makes comeback in San Diego"
The county's aerospace industry has doubled in size during the past decade and badly needs more engineers, according to a new study by the San Diego Workforce Partnership, a publicly funded nonprofit that underwrites job-training programs. The analysis said there are more than 10,000 people working in aerospace operations for companies ranging from defense giant Northrop Grumman, which develops unmanned aerial vehicles, to Quality Controlled Manufacturing, a small precision manufacturing firm

"UCSD group prepares for rocket test launch"
A team of UC San Diego undergraduate students is preparing to test a second rocket engine that could set a world record. The students say UCSD is the first college in the world to build an engine from a 3D Printer. The group, known as Students for the Exploration and Development for Space, or SEDS, built the engine called "Ignus." The students are preparing to use the engine to launch a rocket 10,000 feet in the sky. "We'd have the ability to set a world record," said UCSD student Deepak Atyam.
"Report: To Aid Combat, Russia Wages Cyberwar Against Ukraine"
The rules of War 2.0 (or 3.0) are murky. Experts and pundits say that cyberwarfare is happening. And it makes sense. But it has been very hard to prove. A new report adds to the body of evidence, charging that the Russian military is waging a sustained cyber campaign against Ukrainian military and law enforcement agencies, and the purpose is to extract a steady stream of classified documents that can aid violence and on-the-ground combat.

""Holey" Graphene Improved as an Electrode Material"
Researchers at the University of California San Diego (UCSD) have developed a method for increasing the amount of electric charge that graphene can store as an electrode material in supercapacitors. The key to what the researchers have done is making the graphene "holey." The UCSD team is not the first to recognize the merits of "holey" graphene. Last year, researchers at the California NanoSystems Institute (CNSI) at UCLA developed what they termed a "holey graphene framework;"

"Micromotors to Boost Hydrogen Fuel Cells"
Hydrogen fuel cells promise vehicles whose only emission is water. But their appearance, at least as a one-to-one replacement for internal combustion engines, has been stymied by the challenges of storing hydrogen gas. Now researchers say micromotors could help vehicles generate hydrogen gas on board in order to power hydrogen fuel cells. Hydrogen fuel cells work by combining hydrogen with oxygen from the air to generate electricity and water vapor.

"Researchers create smallest gaps ever in nanostructures using graphene"
There's a lot of talk about graphene these days, and with good reason. Consisting of just a single layer of carbon atoms roughly 0.3 nanometers thick, or 100,000 times thinner than a human hair, graphene is the thinnest known material. A team of PhD students and undergrads at UC San Diego has developed a technique that generates extremely small gaps, or nanogaps. Structures with these atomic-sized gaps could be used to detect single molecules associated with certain diseases

"Secrets of Skin"
Our skin is remarkably resistant to tearing, and now researchers have figured out why. They used X-ray beams and electron microscopes to look at the micro-scale mechanisms at play when rabbit skin is cut and then stretched. A notch in skin does not lead to a full split, as it does in bone, because the initial tear induces structural changes in the collagen fibrils found in the top layer of skin to dissipate the stress at the tip of the cut.
