Southern California coastal towns are losing valuable sand, putting some beaches at risk
The Orange County Register -
If solutions aren’t swift, the Southern California coast — and the economy it supports — will surely suffer. “If we have no sand, it’s like a car and we’ve taken the engine out of it,” said UC Irvine civil engineering professor Brett Sanders, a leading expert on coastal erosion. … UCI grad student Daniel Kahl recently analyzed satellite imagery — a project possible with a $675,000 grant from NASA — to measure beaches through recent decades to find out which are eroding at the fastest pace.

An Orange County coastal town grapples with losing its beach
The Orange County Register -
The shoreline from San Clemente to Dana Point is a microcosm of what issues can arise when the beach disappears from a “beach town” – and how much is at stake for coastal communities when their sand disappears. … UC Irvine civil engineering professor Brett Sanders, a leading expert on sand erosion, said the beach went through what’s called a “tipping point.” South San Clemente had about 200 feet of sand through the 1990s and 2000s, based on satellite imagery analyzed by grad students. … Now, at the point where the railroad damage occurred, there’s no beach at all during higher tides, and only wet sand exposed when tides drop.

Can Southern California save its disappearing beaches?
The Orange County Register -
Sand nourishment isn’t always the best answer. … But UC Irvine civil engineering professor Brett Sanders argues sand replenishment sometimes gets a bad rap. Without sand solutions, some coastal wildlife won’t have places to go. … State Parks is collaborating with UC Irvine to conduct high-tech studies to pinpoint problem areas, said Orange Coast State Parks Superintendent Kevin Pearsall. Researchers are using drone images, topography, monitoring and surveying to measure beaches and track sand movement. [Subscription required, campus-wide access provided by UCI Libraries.

Study reveals new ways microbes might help humans build colonies on Moon, Mars
ANI -
Researchers at the University of California, Irvine have been motivated to consider new ways that microbes can assist humans in colonising the Moon and Mars by studying the biochemical process by which cyanobacteria absorb nutrients from rocks in Chile's Atacama Desert. … Corresponding author David Kisailus, UCI professor of materials science and engineering [said], "Could humans use a similar biochemical approach to obtain and manipulate the minerals that we find valuable? This project has led us down that pathway." Read More

Sea urchins’ sperm pathway could help tiny robots find their way
Interesting Engineering -
University of California, Irvine, and University of Michigan researchers prepared a mathematical model of sea urchin sperm's pathway to grasp its behavior, initially reported by Popular Science. The authors claim that understanding the biological makeup of the sea urchin can be used to create tiny robots that mimic its behavior while taking cues from their environment. Read More
Microbial Miners Could Help Humans Colonize The Moon And Mars
Space Ref -
Researchers in UCI’s Department of Materials Science and Engineering and Johns Hopkins University’s Department of Biology used high-resolution electron microscopy and advanced spectroscopic imaging techniques to gain a precise understanding of how microorganisms modify both naturally occurring minerals and synthetically made nanoceramics. … “Through a biological process that has evolved over millions of years, these tiny miners excavate rocks, extracting the minerals that are essential to the physiological functions, such as photosynthesis, that enable their survival,” said corresponding author David Kisailus, UCI professor of materials science and engineering.

Sea urchin sperm is surprisingly useful to robotics experts
Popular Science -
A study published December 9 in the journal Physical Review E details the similarities between the trajectory of sea urchin sperm and computer systems that use a type of real-time search approach called extremum seeking. Engineers from the University of California, Irvine and University of Michigan made a mathematical model of the sperm’s pathway to better understand its behavior. According to the authors, assessing the sea urchin’s biological nature could help design miniature robots that follow cues from sources in the same way. Read More

Sea Urchin Sperm Follow Their Noses
Physics Magazine -
Now Mahmoud Abdelgalil, [a mechanical & aerospace engineering graduate student] at the University of California, Irvine, and colleagues have discovered an unexpected synergy between established sperm navigation models and concepts from control theory. They developed a robust navigation model that relies on a single parameter: the local concentration gradient of the chemical the sperm cells track. The team says that their model could be used to describe the motion of other organisms that move in response to chemical gradients. Read More
