The unique promise of ‘biological computers’ made from living things

Posted by in categories: biological, robotics/AI

Biologists are finally beginning to corral molecules, cells and whole organisms to carry out complex computations. These living processors could find use in everything from smart materials to new kinds of artificial intelligence.

Discovery in Pacific coral reefs suggests Earth’s microbial diversity may be underestimated

Posted by in categories: biological, sustainability

A two-year expedition to coral reefs in the Pacific Ocean detected half a million types of microbes, the latest estimate in the quest to quantify the planet’s microbiome.

The big picture: There is intense debate among scientists about how many different types of bacteria and other microorganisms live on Earth — information that could aid conservation of species and fragile ecosystems brimming with biodiversity.

Perovskite Sensor Array Emulates Human Retina For Panchromatic Imaging

Posted by in categories: biological, information science, life extension, robotics/AI, solar power, sustainability

The mammalian retina is a complex system consisting out of cones (for color) and rods (for peripheral monochrome) that provide the raw image data which is then processed into successive layers of neurons before this preprocessed data is sent via the optical nerve to the brain’s visual cortex. In order to emulate this system as closely as possible, researchers at Penn State University have created a system that uses perovskite (methylammonium lead bromide, MAPbX3) RGB photodetectors and a neuromorphic processing algorithm that performs similar processing as the biological retina.

Panchromatic imaging is defined as being ‘sensitive to light of all colors in the visible spectrum’, which in imaging means enhancing the monochromatic (e.g. RGB) channels using panchromatic (intensity, not frequency) data. For the retina this means that the incoming light is not merely used to determine the separate colors, but also the intensity, which is what underlies the wide dynamic range of the Mark I eyeball. In this experiment, layers of these MAPbX3 (X being Cl, Br, I or combination thereof) perovskites formed stacked RGB sensors.

The output of these sensor layers was then processed in a pretrained convolutional neural network, to generate the final, panchromatic image which could then be used for a wide range of purposes. Some applications noted by the researchers include new types of digital cameras, as well as artificial retinas, limited mostly by how well the perovskite layers scale in resolution, and their longevity, which is a long-standing issue with perovskites. Another possibility raised is that of powering at least part of the system using the energy collected by the perovskite layers, akin to proposed perovskite-based solar panels.

Quantum Physics Could Explain Nearly All the Mysteries of How Life Works

Posted by in categories: biological, particle physics, quantum physics

Quantum effects are phenomena that occur between atoms and molecules that can’t be explained by classical physics. It has been known for more than a century that the rules of classical mechanics, like Newton’s laws of motion, break down at atomic scales. Instead, tiny objects behave according to a different set of laws known as quantum mechanics.

For humans, who can only perceive the macroscopic world, or what’s visible to the naked eye, quantum mechanics can seem counterintuitive and somewhat magical. Things you might not expect happen in the quantum world, like electrons “tunneling” through tiny energy barriers and appearing on the other side unscathed or being in two different places at the same time in a phenomenon called superposition.

I am trained as a quantum engineer. Research in quantum mechanics is usually geared toward technology. However, and somewhat surprisingly, there is increasing evidence that nature – an engineer with billions of years of practice — has learned how to use quantum mechanics to function optimally. If this is indeed true, it means that our understanding of biology is radically incomplete. It also means that we could possibly control physiological processes by using the quantum properties of biological matter.

Fish evolution takes place in decades — not millions of years

Posted by in categories: biological, evolution, genetics, singularity

Given this new information humans could modify their genetic code to rapidly accelerate their evolution aswell leading to a biological singularity of evolution.

Codfish have been telling a story of rapid fish evolution, reshaped by human activity more swiftly than previously assumed, reveals a cutting-edge study led by Rutgers University.

This evolutionary tale, illuminated during the latter half of the twentieth century, signifies the impact of human-driven overfishing. The findings suggest that evolutionary changes, once thought to span millions of years, can be catalyzed within mere decades.

Forging a dream material with semiconductor quantum dots

Posted by in categories: biological, computing, quantum physics, solar power, sustainability

Researchers from the RIKEN Center for Emergent Matter Science and collaborators have succeeded in creating a “superlattice” of semiconductor quantum dots that can behave like a metal, potentially imparting exciting new properties to this popular class of materials.

Semiconducting colloidal quantum dots have garnered tremendous research interest due to their special optical properties, which arise from the quantum confinement effect. They are used in , where they can improve the efficiency of energy conversion, biological imaging, where they can be used as fluorescent probes, , and even , where their ability to trap and manipulate individual electrons can be exploited.

However, getting to efficiently conduct electricity has been a major challenge, impeding their full use. This is primarily due to their lack of orientational order in assemblies. According to Satria Zulkarnaen Bisri, lead researcher on the project, “making them metallic would enable, for example, quantum dot displays that are brighter yet use less energy than current devices.”
