"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

"UCSD students launch Kickstarter campaign for a completely 3D printed rocked engine"
As you might know, 3D printing technology is heading towards a bright future in the aerospace industry. Various major players have already incorporated high quality 3D printers in their prototyping process, while the first space-bound 3D printed parts are already being created. Just this week, NASA unveiled a 3D printed engine part they actually intend to use. So while this seems like a field for big players only, a team of students from the UCSD in California are challenging the establishment..

"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.

"3D Printed Rocket Engine Project Goes to The Next Level With Ignus Engine & Kickstarter"
The students who are building the Ignus 3D printed rocket engine say it will be "bigger, better, but a completely different design compared to our original Tri-D engine." Students for the Exploration and Development of Space, or SEDS for short, are the undergraduate group at the University of California, San Diego, who designed, printed and tested a 3D printed rocket engine, and they say their latest engine will be placed into the Vulcan-1 rocket body and launched in June.

"UCSD Students Design, Print & Test 3D-Printed Rocket Engine"
With a quick countdown in the middle of the desert, a group of San Diego college students accomplished a milestone -- the design, printing and testing of a 3D printed rocket engine. Over the weekend, Students for the Exploration and Development of Space (SEDS) from UC San Diego gathered to test the engine they had created by depositing plastic or metal alloys layer by layer through a 3D printer. The engine was secured when it was ignited. The firing lasted five seconds...
"UCSD crowdfunds small rocket"
Student engineers at UC San Diego are off to a fast start in trying to raise $15,000 on Kickstarter to develop a rocket capable of soaring almost two miles into the atmosphere. The local chapter of the Students for the Exploration and Development of Space (SEDS) has generated more than $11,600 since April 21st, the first day of their campaign to underwrite a 16-foot tall Vulcan-1 rocket that would be powered by an engine produced with 3-D printing.

"Block the bad sounds and harness the good with Hush earplugs"
This world we live in can be pretty noisy -- especially when you're trying to get some sleep. But tossing in standard earplugs to block out excess sounds, from inside and outside, can cause problems when that alarm clock rings. A new pair of "smart earplugs" called Hush aims to solve this dilemma by keeping the bad sounds out, and letting the good ones in. The earplugs combine sound-eliminating foam with a small driver that plays soothing sounds like white noise, ocean waves, and rain drops.

When weighing the pluses and minuses of your skin add this to the plus column: Your skin - like that of all vertebrates - is remarkably resistant to tearing. Now, a collaboration of researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) San Diego has shown why.
"State reaps rewards on investment in universities"
Among recent public discourse about our state's investment in the University of California, a thoughtful legislator proposed that the state add another campus to the 10-campus system. Using the example of Caltech, he suggested that a new campus focus on science, technology, engineering, mathematics and the arts. The idea is laudable -- as it was some 50 years ago, when legislators, scientists and scholars agreed to establish UC San Diego.
"The complex, mysterious sense of sight"
Mother Nature is an incredible engineer. As you read these words, light is hitting your eyes and being absorbed by your retinas. Your brain interprets the light patterns as letters and words, which is how I'm communicating with you now. How does this happen?

"Why your skin is so tough: Revolting experiment reveals how collagen straightens and stretches when pulled"
It is probably the most unpleasant experiment you will read about today: what happens when your skin starts to tear. Researchers have uncovered the reason why skin is so difficult to tear even when put under extreme pressures, by cutting samples of real skin and attempting to pull them apart. They found that rather than simply tearing, mammalian skin actually has sophisticated stress resistance properties that prevent holes and cuts from expanding.

"New methods to speed simulations in computational grand challenge"
Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical simulations in computational grand challenge problems. Such problems often arise from the high-resolution approximation of the partial differential equations governing complex flows of fluids or plasmas. The breakthrough could be applied to simulations that include millions or billions of variables, including turbulence simulations.

The first study of synthetic micromotors in vivo (in a living organism) is paving the way for future clinical studies, developing medical countermeasures and other lifesaving applications -- ultimately helping to prevent or aid in healing warfighters in harm's way.

Fate spazio nei vostri portapenne. Presto, accanto alle convenzionali biro blu e nere, potrete mettere la penna per disegnare sensori. Il meccanismo e l'estetica saranno quelli di una penna convenzionale ma nella cartuccia scorrerà un inchiostro fatto di nanoparticelle biologiche. Gli ingredienti principali dell'inchiostro, infatti, sono la glucosio ossidasi- un enzima capace di rilevare i livelli di glucosio nel sangue- e la tirosinasi- un altro enzima sensibile a vari agenti inquinanti.

It wasn't that long ago that you had to go to your doctor's office to measure most of your vital signs. But now, you can buy wearable devices that measure your blood pressure, or even record the electrical activity of your heart. So what's next? UC San Diego's Center for Wearable Sensors offers a glimpse.

"The purpose of the trip is to raise eyebrows about this technology," said de Callafon. Gert Lanckriet, a fellow UC San Diego engineering professor, is taking a different but related approach to raising money for technology and innovation. He co-founded Benefunder, a non-profit organization that will use wealth management experts to expose potential donors to the work of top scientists. The wealth managers will do such things as arrange donor visits to labs.
