Neurobiologists discover sensory neurons that control fainting, laying a foundation for targeted treatments for related disorders
Nearly 40 percent of people experience syncope, or fainting spells, at least once in their lives. These brief losses of consciousness, whether brought by pain, fear, heat, hyperventilation or other causes, account for a significant portion of hospital emergency room visits. Yet the exact root mechanisms at play when people “pass out” largely have remained a mystery.

Jan 25 2018Discovery Offers New Genetic Pathway for Injured Nerve Regeneration
Finding could pave road to regrowth after traumatic injuries, stroke and spinal damage
On the hunt for genes involved in regenerating critical nerve fibers called axons, biologists at the University of California San Diego came away with a surprise: The discovery of a new genetic pathway that carries hope for victims of traumatic injuries—from stroke to spinal cord damage.
UC San Diego Biological Sciences Assistant Project Scientist Kyung Won Kim, Professor Yishi Jin and their colleagues conducted a large-scale genetic screening in the roundworm C. elegans seeking ultimately to understand genetic influences that might limit nerve regrowth in humans. Unexpectedly, the researchers found the PIWI-interacting small RNA (piRNA) pathway—long believed to be restricted to function in the germline—plays an active role in neuron damage regeneration.

Nov 2 2017Scientists Decipher Mechanisms Underlying the Biology of Aging
Multi-pronged approach reveals a delicate balance required for longevity
Understanding the factors that control aging has been one of humanity's endless pursuits, from the mystical fountain of youth to practical healthful regimens to prolong life expectancy.
A team of scientists at the University of California San Diego has now helped decipher the dynamics that control how our cells age, and with it implications for extending human longevity. As described in a study published in Proceedings of the National Academy of Sciences, a group led by biologist Nan Hao employed a combination of technologies in engineering, computer science and biology to analyze molecular processes that influence aging.

Oct 5 2017A Flip Flop Revolution
From algae surfboards to sustainable shoes, a campus innovation that could change the world
UC San Diego students and researchers have produced the world's first algae-based, renewable flip flops.
The first prototypes of their new invention, developed over the summer in a York Hall chemistry laboratory, consist of a flexible, spongy slipper adorned with a Triton logo and a simple strap—fairly basic, as flip flops go.
But when they go into full production later this academic year at what researchers hope will be a projected cost of $3 a pair, the impact of this campus innovation could be revolutionary, changing the world for the better environmentally.

May 4 2017Q&A with Heather Henter, Academic Coordinator, UC San Diego Natural Reserve System
The UC Natural Reserve System (NRS) is a network of 39 (soon to be 40) largely undisturbed properties across the state, set aside to fulfill the mission of the UC: education, research and public service. We are different from state/national parks or other wild lands because we are part of a university, thus research and education are a focus. These sites are living laboratories for researchers and classrooms without walls for students. And because we are a system, we can address important topics like climate change ecosystem-wide. The network includes most habitats in the state, from coast to desert to alpine.

Researchers at the University of California San Diego and the Massachusetts Institute of Technology (MIT) have come up with a strategy for using synthetic biology in therapeutics. The approach enables continual production and release of drugs at disease sites in mice while simultaneously limiting the size, over time, of the populations of bacteria engineered to produce the drugs. The findings are published in the July 20 online issue of Nature.

You are only 10 percent human. Ninety percent of the cells that make up our bodies are actually bacteria, viruses, fungi and other microbes. And researchers are now finding that these unique microbial communities — called microbiomes — can greatly influence human and environmental health. The human gut microbiome alone has now been linked to allergies, inflammatory bowel disease, obesity and many other conditions.

With their tiny forelimbs and long hindlimbs and feet, jerboas are oddly proportioned creatures that look something like a pint-size cross between a kangaroo and the common mouse.
How these 33 species of desert-dwelling rodents from Northern Africa and Asia evolved their remarkable limbs over the past 50 million years from a five-toed, quadrupedal ancestor shared with the modern mouse to the three-toed bipedal jerboa is detailed in a paper published in this week's issue of the journal Current Biology.

Far from being selfish organisms whose sole purpose is to maximize their own reproduction, bacteria in large communities work for the greater good by resolving a social conflict among individuals to enhance the survival of their entire community.
It turns out that, much like human societies, bacterial communities benefit when they can balance opposing needs within the group.
