Artificial intelligence and machine learning hardware research have concentrated on building photonic synapses and neurons and combining them to do fundamental forms of neural-type processing. However, complex processing methods found in human brains—such as reinforcement learning and dendritic computation—are more challenging to replicate directly in hardware.
A new study contributes to closing the “hardware gap” by creating an “Optomemristor” device that responds to numerous electronic and photonic inputs at the same time. The diverse biophysical mechanisms that govern the functions of the brain’s neurons and synapses allow for complex learning and processing in the mammalian brain.
The chalcogenide thin-film technology interacts with both light and electrical impulses to mimic multifactor biological computations in mammalian brains while spending very little energy.
Our teams explore burgeoning research areas and inventing revolutionary technology that will not only accomplish the mission at hand but also influence our world.
Researchers, led by experts at Imperial College London, have developed a new method that allows gene expression to be precisely altered by supplying and removing electrons.
This could help control biomedical implants in the body or reactions in large ‘bioreactors’ that produce drugs and other useful compounds. Current stimuli used to initiate such reactions are often unable to penetrate materials or pose risk of toxicity—electricity holds the solution.
Gene expression is the process by which genes are ‘activated’ to produce new molecules and other downstream effects in cells. In organisms, it is regulated by regions of the DNA called promoters. Some promoters, called inducible promoters, can respond to different stimuli, such as light, chemicals and temperature.
A cellphone-sized device automatically adjusts a home’s power use up or down to save the consumer money and increase the resiliency of the electric grid.
The effects of climate change are pushing electrical grids around the world to their limits. Last year, unprecedented cold weather caused people in Texas to turn up their thermostats, which overwhelmed the power grid and caused days-long power outages. And in California, the power is turned off before there is a high possibility of a fire.
To combat the electric grid’s vulnerabilities and cut down on the use of non-renewable sources of energy, researchers at the Department of Energy’s SLAC National Accelerator Laboratory have developed technology that automatically adjusts a home’s power use up or down in response to fluctuating prices that are established by real-time market demand.
Yemoja researchers combined Porphyridium algae derivatives after developing a groundbreaking system for the biological culture of pure and standardized components from micro-algae intended for the food and cosmetics industries.
Communicate and find patterns with sound as your guide. “Sonification — When You Go Beyond the Visual Representation Of Data” is published by Pavle Marinkovic in Towards Data Science.
Many researchers believe that liquid water is a key to understanding the behavior of the frozen form found in glaciers. Meltwater is known to lubricate their gravelly bases and speed up their march toward the sea. In recent years, scientists in Antarctica have discovered hundreds of interconnected liquid lakes and rivers cradled within the ice itself. And, they have imaged thick basins of sediments under the ice, potentially containing the biggest water reservoirs of all. But so far, no one has confirmed the presence of large amounts of liquid water in below-ice sediments, nor investigated how it might interact with the ice.
Now, a research team has for the first time mapped a huge, actively circulating groundwater system in deep sediments in West Antarctica. They say such systems, probably common in Antarctica, may have as-yet unknown implications for how the frozen continent reacts to, or possibly even contributes to, climate change. The research was published in the journal Science on May 5, 2022.
