Growing brains can be a tricky process, but growing ones that can make muscles move? That’s an incredible feat. Here’s how scientists did it.

Cerebral organoids at the air-liquid interface generate nerve tracts with functional output.

“The capacity for this model to be used to investigate the way in which neurons connect up within the brain and with the spinal cord could have important implications for our understanding of a range of diseases. In particular defects in neuronal connectivity are thought to underlie various psychiatric illnesses, including schizophrenia, autism, and depression. ”

“Finally, through electrophysiological and co-culture studies, we demonstrate functionality of these tracts, which are even capable of eliciting coordinated muscle contractions in co-cultured mouse spinal cord–muscle explants. This approach is likely to be a useful new tool, not only because of its ease, but also due to its util-ity in studying axon guidance, tract formation, and connectivity in a human system”

What’s Wrong With Growing Blobs of Brain Tissue?

“The stuff we really care about in the brain, like consciousness, are emergent phenomena—they arise from the collective workings of individual neurons, which create a whole that’s greater than the sum of its parts. The problem is that we don’t know at what level these phenomena emerge. A neuron is not conscious. A person is. What about all the steps in the middle? What about 2 million neurons? 20 million? 200 million?”

Food tech startup Farther Farms has developed a process that keeps foods that would normally need to be refrigerated or frozen fresh at room temperature — and their first product is a bag of shelf-stable French fries.

The cold chain: Microorganisms are a major cause of food spoilage, and they thrive at room temperature. By keeping some foods cold, we can slow the growth of these microbes, extending the life of the food.

To do that, the foods must be prepared, shipped, and stored along a temperature-controlled supply chain (a “cold chain”). If the cold chain is broken at any point along the way, the food may quickly become unsafe to eat.

GARMI will also serve meals, open a bottle of water and place emergency calls.

Robots are gradually making their way into a variety of industries, from restaurant service to healthcare. Scientists have been working hard to rapidly expand robot capabilities, and it is clear that robotics will shape our daily lives in the near future.

Now, it’s time to meet “GARMI”. This white-colored humanoid which has come to the aid of doctors, nurses, and elderly citizens in need.

Medicine and elderly healthcare could benefit the most from robotics advancements.

ChatGPT launched a tide wave of interest in AI. For many consumers, AI is finally living up to long overdue expectations. The accomplishments of ChatGPT in a short period of time are phenomenal. But what is yet to come when AI is combined with robotics will change everything.

I have been promoting the advances in robotics for several years. I even called 2022 the year of robotics, partially because of the growing need to overcome shortages in labor and to handle tasks beyond the physical or mental capability of humans, and partially because of the continued advances that AI, accelerated processing, semiconductor, sensors, wireless connectivity, and software technologies are enabling to develop advanced, autonomous machines. Robots are no longer just for the manufacturing floor. They are hazardous material handlers, janitors, personal assistants, food preparers, food deliverers, security guards, and even surgeons that are increasingly autonomous. Essentially, they are AI in the physical world. As a result, robot competitions are heating up from middle schools to Las Vegas.

As seen at CES, robotics technology is advancing rapidly with advances in technology. My favorite examples were the multi-configurable Yarbo outdoor robot and the John Deere See & Spray. Yarbo can be a mower, a leaf blower, or a snow blower. If it could dispose of animal excrement and the annoying neighbor, it would be perfect yard tool. On the other end of the spectrum was the John Deere See & Spray Ultimate, a tractor with up to a 120-foot (36.6m) reach that uses AI/ML to detect weeds smaller than the size of a smart phone camera and spray herbicide accordingly. John Deere also offers self-drive tractors.

A system of robots that harvest and transport crops on their own without human assistance has been developed for use in agricultural facilities such as smart farms.

The research team under Choi Tae-yong, principal researcher at the AI Robot Research Division’s Department of Robotics and Mechatronics of the Korea Institute of Machinery and Materials, an institution under the jurisdiction of the Ministry of Science and ICT, has developed a multiple-robot system for harvesting crops.

This technology can be used to help at agricultural sites where there is a noticeable shortage of manpower by harvesting crops through an automated system. This system also includes robots that use autonomous driving technology to then transport the harvested crops to loading docks.

A trio of evolutionary biologists, two with Carleton University, the other with Seoul National University, has apparently solved the paradox of aposematism—how animals managed to evolve with bright colors to warn predators of their toxic nature. In their paper study, published in the journal Science, Karl Loeffler-Henry, Changku Kang and Thomas Sherratt, conducted an analysis of the family tree of over 1,000 frog, salamander and newt species.

For many years, have puzzled over the seeming paradox of aposematism, in which such as frogs develop to warn potential predators that eating them will make them sick or even kill them. How could such colors have evolved? Animals that stand out tend to be the first caught and eaten, preventing the evolution of even brighter colors from occurring. In this new effort, the research team set out to solve this riddle.

The work involved analyzing the of 1,100 species of frogs, salamanders and newts, looking for evidence of evolution of aposematism in a new way—by breaking them down into more categories than previous efforts—five instead of two: conspicuous, cryptic, partially conspicuous, fully conspicuous and polymorphic.

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.

Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus.

“Extracts from these so-called ‘lion’s mane’ mushrooms have been used in in Asian countries for centuries, but we wanted to scientifically determine their on ,” Professor Meunier said.
