The Rise of Pico Technology

Posted by in categories: biotech/medical, chemistry, computing, quantum physics

In the vast realm of scientific discovery and technological advancement, there exists a hidden frontier that holds the key to unlocking the mysteries of the universe. This frontier is Pico Technology, a domain of measurement and manipulation at the atomic and subatomic levels. The rise of Pico Technology represents a seismic shift in our understanding of precision measurement and its applications across diverse fields, from biology to quantum computing. Pico Technology, at the intersection of precision measurement and quantum effects, represents the forefront of scientific and technological progress, unveiling the remarkable capabilities of working at the picoscale, offering unprecedented precision and reactivity that are reshaping fields ranging from medicine to green energy.

Unlocking the Picoscale World

At the heart of Pico Technology lies the ability to work at the picoscale, a dimension where a picometer, often represented as 1 × 10^−12 meters, reigns supreme. The term ‘pico’ itself is derived from the Greek word ‘pikos’, meaning ‘very small’. What sets Pico Technology apart is not just its capacity to delve deeper into smaller scales, but its unique ability to harness the inherent physical, chemical, mechanical, and optical properties of materials that naturally manifest at the picoscale.

An organic artificial spiking neuron for in situ neuromorphic sensing and biointerfacing

Posted by in categories: biological, chemistry, robotics/AI

An organic artificial neuron that is based on a compact nonlinear electrochemical element can operate in a liquid and responds to the concentration of biological species in its surroundings, allowing its behaviour to be modulated, for example, by interfacing with the membranes of living cells.

Scientists Extend Life Span in Mice by Restoring This Brain-Body Connection

Posted by in categories: bioengineering, chemistry, genetics, life extension, neuroscience

When young, these neurons signal fatty tissues to release energy fueling the brain. With age, the line breaks down. Fat cells can no longer orchestrate their many roles, and neurons struggle to pass information along their networks.

Using genetic and chemical methods, the team found a marker for these neurons—a protein called Ppp1r17 (catchy, I know). Changing the protein’s behavior in aged mice with genetic engineering extended their life span by roughly seven percent. For an average 76-year life span in humans, the increase translates to over five years.

The treatment also altered the mice’s health. Mice love to run, but their vigor plummets with age. Reactivating the neurons in elderly mice revived their motivation, transforming them from couch potatoes into impressive joggers.

Model outlines how ionic blockades influence energy recovery in forward bias bipolar membranes

Posted by in categories: chemistry, energy

Bipolar membranes (BPMs) are a class of ion-exchange membranes typically comprising a cation-and an anion-exchange layer. While these membranes have recently been integrated in various electrochemical devices for a wide range of application, the processes underlying their operation are not yet fully understood.

Researchers at the Massachusetts Institute of Technology (MIT) recently developed a new mechanistic model that explains the forward bias polarization mechanisms of BPMs in mixed electrolytes with varying acidities and basicities. Their model, introduced in Nature Energy, could guide the development of strategies to overcome the issue of ionic blockades, which can adversely impact the performance of forward bias BPM devices.

“We were initially trying to design an electrolyzer that converts carbon dioxide CO2 into useful feedstocks or fuels using bipolar membranes (BPMs),” Yogesh Surendranath, co-author of the paper, told Tech Xplore. “To provide a little context, CO2 electrolyzers are most efficient when operating with alkaline electrolyte solutions such as , but because CO2 is an acid gas, it reacts with alkaline solutions to produce carbonate solutions over time.”

Probing the chemical ‘reactome’ with high-throughput experimentation data

Posted by in categories: chemistry, robotics/AI

Using #AI to define the chemical “reactome”—the important functional sites in small molecules.


High-throughput experimentation (HTE) has great utility for chemical synthesis. However, robust interpretation of high-throughput data remains a challenge. Now, a flexible analyser has been developed on the basis of a machine learning-statistical analysis framework, which can reveal hidden chemical insights from historical HTE data of varying scopes, sizes and biases.

Physicists identify overlooked uncertainty in real-world experiments

Posted by in categories: chemistry, information science, physics

The equations that describe physical systems often assume that measurable features of the system—temperature or chemical potential, for example—can be known exactly. But the real world is messier than that, and uncertainty is unavoidable. Temperatures fluctuate, instruments malfunction, the environment interferes, and systems evolve over time.

Water molecule discovery contradicts textbook models

Posted by in categories: chemistry, climatology

Textbook models will need to be re-drawn after a team of researchers found that water molecules at the surface of salt water are organized differently than previously thought.

Many important reactions related to climate and environmental processes take place where interface with air. For example, the evaporation of ocean water plays an important role in atmospheric chemistry and climate science. Understanding these reactions is crucial to efforts to mitigate the human effect on our planet.

The distribution of ions at the interface of air and water can affect atmospheric processes. However, a precise understanding of the microscopic reactions at these important interfaces has so far been intensely debated.
