Imagine if all childhood vaccines could get delivered with an inhaler rather than shots; or wiping away tuberculosis bacteria in a patient’s lungs with an inhaler; or disinfecting a hospital room thoroughly with a diffuser. These are the goals of a research team led by Professor James Friend in the Department of Mechanical and Aerospace Engineering at the University of California San Diego. Their efforts were recently boosted when Friend received a prestigious $900,000 research grant from the Keck Foundation, whose mission is to support pioneering discoveries in science, engineering and medical research.

Someone who starts mining a crypto-currency shortly after it is listed on exchanges can potentially earn higher returns than average. But a speculator who enters the market shortly after the currency is listed might potentially earn lower returns. These are some of the findings from a study where computer scientists estimated the potential profitability of mining versus speculating for 18 crypto-currencies that are not Bitcoin and Litecoin--known under the general label of altcoin. Computer scientists also showed that returns from mining a random altcoin tend to be less risky to earn than returns from speculation.

A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours—essentially an electrocardiogram but for the gastro-intestinal (GI) tract. Applications include monitoring GI activity for patients outside of a clinical setting, which cuts down costs. Monitoring for longer periods of time also increases the likelihood of capturing abnormal events. Researchers detail their findings in the March 22 issue of Nature’s open access journal Scientific Reports.

A team of researchers has developed a light-activated switch that can turn genes on and off in mammalian cells. This is the most efficient so-called “optogenetic switch” activated by red and far-red light that has been successfully designed and tested in animal cells—and it doesn’t require the addition of sensing molecules from outside the cells.

The next computer-generated animals in King Kong or The Lion King could look a lot more realistic thanks to a breakthrough by computer scientists at the University of California. The researchers from UC San Diego and UC Berkeley developed a method that dramatically improves the way computers simulate fur, and more specifically, the way light bounces within an animal’s pelt.

A team of scientists has developed an algorithm that can accurately pinpoint, in large regions of the human genome, mutations favored by natural selection. The finding provides deeper insight into how evolution works, and ultimately could lead to better treatments for genetic disorders. For example, adaptation to chronic hypoxia at high altitude can suggest targets for cardiovascular and other ischemic diseases.

In a paper published in Nature Microbiology on Jan. 22, a team of American and Russian computer scientists described a new algorithm that identified an order of magnitude, or roughly 10 times more, naturally occurring antibiotics all previous studies.

Computer scientists have built and successfully tested a tool designed to detect when websites are hacked by monitoring the activity of email accounts associated with them. The researchers were surprised to find that almost 1 percent of the websites they tested had suffered a data breach during their 18-month study period, regardless of how big the companies' reach and audience are.

A team of bioengineers and bioinformaticians at the University of California San Diego have discovered how the environment surrounding a tumor can trigger metastatic behavior in cancer cells. Specifically, when tumor cells are confined in a dense environment, the researchers found that they turn on a specific set of genes and begin to form structures that resemble blood vessels.

The University of California San Diego will turn its campus into a test bed for self-driving vehicles starting in January 2018. The project will be implemented in stages. The first will be to put self-driving mail delivery carts on the road. The carts will run on algorithms developed by UC San Diego researchers who are part of the Contextual Robotics Institute. Back-up drivers will initially ride in the carts as a safety measure.
