Bacterial Communities Use Sophisticated Strategy to Communicate over Long Distances

Science & Environment

A concept known as “percolation” is helping microbiologists at UC San Diego explain how communities of bacteria can effectively relay signals across long distances. Once regarded as simple clusters of microorganisms, communities of bacteria have been found to employ a strategy we use to brew coffee and extract oil from the sea. Percolation helps the microscopic community thrive and survive threats, such as chemical attacks from antibiotics.

Researchers Characterize “Mutational Burden” of Human Induced Pluripotent Stem Cells

Health & Behavior

In a new study, published in this week’s issue of Cell Reports, researchers at the University of California San Diego School of Medicine scrutinized the whole genome sequences of 18 induced pluripotent stem cell lines derived from skin cells that they had reprogrammed to identify and characterize somatic mutations.

UC San Diego Selected to Lead Development of Open-Source Tools for Hardware Design Automation

Science & Environment

The University of California San Diego has been awarded $11.3 million over four years from DARPA to lead a multi-institution project which aims to develop electronic design automation tools for 24-hour, no-human-in-the-loop hardware layout generation.

Scientists Introduce New Way to Mimic ‘Machine of Machines’

Science & Environment

Like small-scale Legos clicking into place, nature autonomously puts together microscopic building blocks. Living systems are biochemical machines that excel at building and moving their parts. Just as machines need energy in some form to operate, living systems are energized by consuming “fuel”—substances or food—reliably. The human body, for example, contracts muscles by the motion of tiny nanomotors—molecular devices that convert energy at the nanoscale scale to generate movement at the macroscale. The ability to mimic nature’s self-assembly would revolutionize science’s approach to synthesizing materials that could heal, contract or reconfigure.

Nanocrystals Emit Light by Efficiently ‘Tunneling’ Electrons

Science & Environment

Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently “tunneling” electrons through a tiny barrier. The work brings plasmonics research a step closer to realizing ultra-compact light sources for high-speed, optical data processing and other on-chip applications.

UC San Diego Researchers Receive Funding to Pursue Novel Stem Cell-based Treatments

Health & Behavior

The governing board of the California Institute for Regenerative Medicine (CIRM) unanimously approved this week two grants worth more than $2.2 million to University of California San Diego School of Medicine researchers investigating stem cell-based therapies for a rare genetic disorder that affects the heart and a chronic, progressive affliction of the lungs.
