Computer scientists show how bacteria can fuel low-power sensors

Computer scientists at the University of California San Diego are showing how soil microbes can be harnessed to fuel low-power sensors. This opens new possibilities for microbial fuel cells (MFCs), which can power soil hydration sensors and other devices.

Led by Department of Computer Science and Engineering (CSE) Assistant Professor Pat Pannuto and Gabriel Marcano, a Ph.D. student working with Pannuto, this research was presented today at the first Association for Computer Machinery (ACM) Workshop on No Power and Low Power Internet of Things.

“Our most immediate applications are in agricultural settings, trying to create closed-loop controls. First for watering, but eventually for fertilization and treatment: sensing nitrates, nitrogen, phosphorous, potassium. This could help us understand how to limit run off and other effects,” said Pannuto, senior author on the study titled “Soil Power? Can Microbial Fuel Cells Power Non-Trivial Sensors?”

‘Informational simplicity’ may explain why nature favors symmetry

In biology, symmetry is typically the rule rather than the exception. Our bodies have left and right halves, starfish radiate from a central point and even trees, though not largely symmetrical, still produce symmetrical flowers. In fact, asymmetry in biology seems quite rare by comparison.

Does this mean that evolution has a preference for symmetry? In a new study, an international group of researchers, led by Iain Johnston, a professor in the Department of Mathematics at the University of Bergen in Norway, says it does.

1000X More Efficient Neural Networks: Building An Artificial Brain With 86 Billion Physical (But Not Biological) Neurons

Which, to me, sounds both unimaginably complex and sublimely simple.

Sort of like, perhaps, like our brains.

Building chips with analogs of biological neurons and dendrites and neural networks like our brains is also key to the massive efficiency gains Rain Neuromorphics is claiming: 1,000 times more efficient than existing digital chips from companies like Nvidia.

Research On Humans Adapting, Living & Working In Space — Colonel (ret) Dr. Samantha Weeks, Ph.D., Polaris Dawn, Science & Research Director

Colonel (ret) Dr. Samantha “Combo” Weeks, Ph.D. is the Science & Research Director, of the Polaris Dawn Program (https://polarisprogram.com/dawn/), a planned private human spaceflight mission, operated by SpaceX on behalf of Shift4 Payments CEO Jared Isaacman, planned to launch using the Crew Dragon capsule.

Polaris Dawn is the first of three planned missions in the Polaris Program (https://polarisprogram.com/), which endeavors to rapidly advance human spaceflight capabilities by demonstrating new technologies and conducting extensive scientific research to expand our knowledge of humans adapting, living and working in space. Much of this research also has purpose and applicability to improve life here on Earth.

Colonel Dr. Weeks, is a retired United States Air Force Colonel, with over 2,200 hours flying the F-15C, F-16, and T-38, including 105 combat hours. She commanded at the squadron, group, and wing level in the Air Force, and today also serves a corporate Vice President at the Shift4 Payments company, focusing on transformation and change management. Her position as Science & Research Director with Polaris comes after two and a half decades of focus on human performance in aviation.

Colonel Dr. Weeks has a BS in Biology from the United States Air Force Academy, a Masters in Human Relations from University of Oklahoma, and a Ph.D. in Military Strategy / Leadership from the United States Air Force, Air University.

Marmots may hold the secret to longevity

This disparity gets at the difference between one’s chronological age — how old they are in years — and their biological age, which is how their body has aged naturally and in response to its environment. The two can diverge in ways that are either blessings or curses. Hence why those who grow up under extreme stress or in polluted environments may look much older than they actually are.

And yellow-bellied marmots can tell us something about these two ages.

Yellow-bellied marmots (Marmota flaviventer) are no burrow-dwelling meteorologists like the groundhog. They may sound craven, but these quirky critters, also known as whistle pigs, make for fascinating subjects: the cat-sized rodents have a longer lifespan than expected for a mammal of their size. On average, marmots live 15 years.

Exocortex: Thought this might be of some interest

An is an external information processing system that augments the brain’s biological high-level cognitive processes.

An individual’s would be comprised of external memory modules 0, processors 0, IO devices and software systems that would interact with, and augment, a person’s biological brain. Typically this interaction is described as being conducted through a direct brain-computer interface 0, making these extensions functionally part of the individual’s mind.

Individuals with significant exocortices can be classified as transhuman beings.
