Biological AI? Company combines brain cells with silicon chips for smarter artificial intelligence

Posted by in categories: biological, robotics/AI

Cortical Labs takes neurons from mice and put them on chips, then teaches them how to play ping pong.

Can you make smarter AI systems by combining biological neurons with silicon chips? In this episode of The AI Show with John Koetsier, we’re going to chat with Hon Weng Chong, CEO and co-founder of Cortical Labs and Andy Kitchen, the company’s CTO, about biological AI: mixing real brain cells with silicon computer chips.

Mimicking the function of Ruffini receptors using a bio-inspired artificial skin

Posted by in categories: biological, cyborgs, habitats, health, robotics/AI

Mobile robots are now being introduced into a wide variety of real-world settings, including public spaces, home environments, health care facilities and offices. Many of these robots are specifically designed to interact and collaborate with humans, helping them to complete hands-on physical tasks.

To improve the performance of on interactive and manual tasks, roboticists will need to ensure that they can effectively sense stimuli in their environment. In recent years, many engineers and material scientists have thus been trying to develop systems that can artificially replicate biological sensory processes.

Researchers at Scuola Superiore Sant’Anna, Ca’ Foscari University of Venice, Sapienza University of Rome and other institutes in Italy have recently used an artificial skin and a that could be used to improve the tactile capabilities of both existing and newly developed robots to replicate the function of the so-called Ruffini receptors. Their approach, introduced in a paper published in Nature Machine Intelligence, replicates the function of a class of cells located on the human superficial dermis (i.e., subcutaneous skin tissue), known as Ruffini receptors.

Artificial photosynthesis can produce food without sunshine

Posted by in categories: bioengineering, biological, chemistry, food, solar power, sustainability

Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. This process, however, is very inefficient, with only about 1% of the energy found in sunlight ending up in the plant. Scientists at UC Riverside and the University of Delaware have found a way to bypass the need for biological photosynthesis altogether and create food independent of sunlight by using artificial photosynthesis.

The research, published in Nature Food, uses a two-step electrocatalytic process to convert , electricity, and water into acetate, the form of the main component of vinegar. Food-producing organisms then consume acetate in the dark to grow. Combined with to generate the electricity to power the electrocatalysis, this hybrid organic-inorganic system could increase the conversion efficiency of sunlight into , up to 18 times more efficient for some foods.

“With our approach we sought to identify a new way of producing food that could break through the limits normally imposed by biological photosynthesis,” said corresponding author Robert Jinkerson, a UC Riverside assistant professor of chemical and environmental engineering.

Our universe was made by aliens in a lab, theorises Harvard scientist

Posted by in categories: biological, climatology, genetics, habitats, quantum physics, sustainability

Ever considered the notion that everything around you was cooked up by aliens in a lab? Theoretical physicist and former chair of Harvard’s astronomy department, Abraham ‘Avi’ Loeb, has proposed a wild – if unsettling – theory that our universe was intentionally created by a more advanced class of lifeform.

In an op-ed for Scientific American, “Was Our Universe Created In A Laboratory?”, Loeb suggested that aliens could have created a ‘baby universe’ using ‘quantum tunneling’, which would explain our universe’s ‘flat geometry’ with zero net energy. If this discovery were proven true, then the universe humans live in would be shown to be “like a biological system that maintains the longevity of its genetic material through multiple generations,” Loeb wrote.

Loeb put forward the idea of a scale of developed civilisations (A, B, etc.) and, due to that fact that on Earth we currently don’t have the ability to reproduce the astrophysical conditions that led to our existence, “we are a low-level technological civilisation, graded class C on the cosmic scale” (essentially: dumb). We would be higher up, he added, if we possessed the ability to recreate the habitable conditions on our planet for when the sun will die. But, due to our tendency to “carelessly destroy the natural habitat” on Earth through climate change, we should really be downgraded to class D.

Feeding ‘Supplements’ to Corals Could One Day Help to Regrow The Great Barrier Reef

Posted by in category: biological

The corals we find in the world’s reefs have their own microbiomes, and scientists are figuring out how to feed them probiotic ‘supplements’ – to try and save them for future generations.

A baby coral begins life as a swimming larva adrift in the ocean. When it is big enough, the larva sinks and secures itself to the seafloor – or, if it’s lucky, a healthy reef. Once settled, it begins to clone itself.

Shallow-water corals, made up of myriad different organisms, are essentially colonies of tiny animals collaborating with a marine algae called zooxanthellae, which feeds the coral and helps produce the calcium carbonate that forms reefs over thousands – or even millions – of years.

Optical technique sorts nanodiamonds

Posted by in categories: biological, nanotechnology, quantum physics

A method of optically selecting and sorting nanoparticles according to their quantum mechanical properties has been developed by researchers in Japan. The method could prove a crucial tool for manufacturing nanostructures for quantum sensing, biological imaging and quantum information technology ( Sci. Adv. 7 eabd9551).

Scientists have several ways of manipulating and positioning tiny objects without touching them. Optical tweezers, for example, use a highly focused laser beam to generate optical forces that hold and move objects in the beam’s trajectory. However, such tweezers struggle to grasp nanoparticles because these tiny objects are much smaller than the wavelength of the laser light used.

Now, a team led by Hajime Ishihara of Osaka University and Keiji Sasaki at Hokkaido University has developed a way of using light to sort nanodiamonds. These are tiny pieces of semiconductor with very useful optoelectronic properties that derive from bulk diamond as well as certain defects such as nitrogen-vacancy (NV) centres.

A new breakthrough in biology allows scientists to grow food without sunlight

Posted by in categories: biological, climatology, solar power, space, sustainability

The researchers also optimized their electrolyzer to produce the highest levels of acetate ever produced in an electrolyzer to date. What’s more, they found that crop plants, including cowpea, tomato, rice, green pea, and tobacco, all have the potential to be grown in the dark using the carbon from acetate. There’s even a possibility that acetate could improve crop yields, though more research is required.

The researchers believe that by reducing the reliance on direct sunlight, artificial photosynthesis could provide an important alternative for food growth in the coming years, as the world adapts to the worst effects of climate change — including droughts, floods, and reduced land availability. “Using artificial photosynthesis approaches to produce food could be a paradigm shift for how we feed people. By increasing the efficiency of food production, less land is needed, lessening the impact agriculture has on the environment. And for agriculture in non-traditional environments, like outer space, the increased energy efficiency could help feed more crew members with less inputs,” Jinkerson explained.
