A team of researchers at the Italian Institute of Technology recently unveiled what is being billed as the worldâs first fully rechargeable, edible battery. As detailed in a paper published with Advanced Materials, the new device utilizes riboflavin (often found in shiitake mushrooms) as its anode and quercetin (seen in capers) as the cathode. Activated charcoal amplified the electrical conductivity alongside a water-based electrolyte. Nori seaweedâmost often seen in sushiâserved as the short circuit prevention separator, while beeswax-encased electrodes and food-grade gold foil contacts also contributed to the design.
The battery relies on chemical components often found in shiitake mushrooms, capers, and seaweedâand may come in handy for childrenâs toys.
When London-based student Lewis Hornby noticed that his dementia-afflicted grandmother was having trouble staying hydrated, he came up with Jelly Drops, bite-sized pods of edible water made with gelling agents and electrolytes.
For more than a century, biologists have wondered what the earliest animals were like when they first arose in the ancient oceans more than half a billion years ago.
Searching among todayâs most primitive-looking animals for the earliest branch of the animal tree of life, scientists gradually narrowed the possibilities down to two groups: sponges, which spend their entire adult lives in one spot, filtering food from seawater; and comb jellies, voracious predators that oar their way through the worldâs oceans in search of food.
In a new study published this week in the journal Nature, researchers use a novel approach based on chromosome structure to come up with a definitive answer: Comb jellies, or ctenophores (pronounced teenâ-a-fores), were the first lineage to branch off from the animal tree. Sponges were next, followed by the diversification of all other animals, including the lineage leading to humans.
Lions mane the mushroom can actually stop alzheimers and dementia by boosting nerve growth đđ
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.
âExtracts from these so-called âlionâs maneâ mushrooms have been used in traditional medicine in Asian countries for centuries, but we wanted to scientifically determine their potential effect on brain cells,â Professor Meunier said.
One fish, swimming alone, encountering a robotic fish impersonator will be wary and tend to avoid the robot, but a group of real fish are more likely to accept the robot as one of their own, and sometimes even abandon other real fish to follow the robot.
Those are the findings of engineers from Peking University and China Agricultural University who created a realistic koi fish robot, and placed one or two in a tank with real fish to see how they would respond.
Perhaps your real life is so rich you donât have time for another.
Even so, the US Department of Defense (DOD) may already be creating a copy of you in an alternate reality to see how long you can go without food or water, or how you will respond to televised propaganda.
The DOD is developing a parallel to Planet Earth, with billions of individual ânodesâ to reflect every man, woman, and child this side of the dividing line between reality and AR.
Using a specially designed capsule, researchers can now voyage through the digestive system, collecting new data about digestion and microorganisms. The work by a team including researchers at the University of California, Davis, Stanford University and Envivo Bio Inc., is published May 10 in papers in Nature and Nature Metabolism.
Most of the process of digestion takes place in our small intestine, where enzymes break down food so it can be absorbed through the gut wall.
âThe small intestine has so far only been accessible in sedated people who have fasted, and thatâs not very helpful,â said Professor Oliver Fiehn, director of the West Coast Metabolomics Center at UC Davis. Metabolomics is the study of the metabolome, the small molecules involved in metabolism in cells, tissues and organs. Fiehn is senior author on the Nature Metabolism paper and co-corresponding author on the Nature paper. Jacob Folz, a postdoctoral researcher at UC Davis, is first author on the Nature Metabolism paper.
In recent decades, engineers have created a wide range of robotic systems inspired by animals, including four legged robots, as well as systems inspired by snakes, insects, squid and fish. Studies exploring the interactions between these robots and their biological counterparts, however, as still relatively rare.
Researchers at Peking University and China Agricultural University recently set out to explore what happens when live fish are placed in the same environment as a robotic fish. Their findings, published in Bioinspiration & Biomimetics, could both inform the development of fish-inspired robots and shed some new light on the behavior of real fish.
âOur research team has been focusing on the development of self-propelled robotic fish for a considerable amount of time,â Dr. Junzhi Yu, one of the researchers who carried out the study, told Tech Xplore. âDuring our field experiments, we observed an exciting phenomenon where live fish were observed following the swimming robotic fish. We are eager to further explore the underlying principles behind this phenomenon and gain a deeper understanding of this âfish followingâ behavior.â
DNA writing is an aspect of our industry that Iâve been closely watching for several years because it is a critical component of so many groundbreaking capabilities, from cell and gene therapies to DNA data storage. At the SynBioBeta Conference in 2018, the co-founder of a new startup that was barely more than an idea gave a lightning talk on enzymatic DNA synthesis â and I was so struck by the technology the company was aiming to develop that I listed them as one of four synthetic biology startups to watch in 2019. I watched them, and I wasnât disappointed.
Ansa Biotechnologies, Inc. â the Emeryville, California-based DNA synthesis startup using enzymes instead of chemicals to write DNA â announced in March the successful de novo synthesis of a 1005-mer, the worldâs longest synthetic oligonucleotide, encoding a key part of the AAV vector used for developing gene therapies. And thatâs just the beginning. Co-founder Dan Lin-Arlow will be giving another lightning talk at this yearâs SynBioBeta Conference in just a few weeks. I caught up with him in the lead up and was truly impressed by what Ansa Biotechnologies has accomplished in just 5 years.
Synthetic DNA is a key enabling technology for engineering biology. For nearly 40 years, synthetic DNA has been produced using phosphoramidite chemistry, which facilitates the sequential addition of new bases to a DNA chain in a simple cyclic reaction. While this process is incredibly efficient and has supported countless innovative breakthroughs (a visit to Twist Bioscienceâs website will quickly educate you on exciting advances in drug discovery, infectious disease research, cancer therapeutics, and even agriculture enabled by synthetic DNA) it suffers from two main drawbacks: its reliance on harsh chemicals and its inability to produce long (read: complex) DNA fragments.
