Lions mane the mushroom can actually stop alzheimers and dementia by boosting nerve growth 😗😁

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.

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 don’t 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.

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.

“The small intestine has so far only been accessible in sedated people who have fasted, and that’s not very helpful,” 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.

“Our research team has been focusing on the development of self-propelled robotic fish for a considerable amount of time,” Dr. Junzhi Yu, one of the researchers who carried out the study, told Tech Xplore. “During 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 ‘fish following’ behavior.”

DNA writing is an aspect of our industry that I’ve 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 — 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 wasn’t disappointed.

Ansa Biotechnologies, Inc. — the Emeryville, California-based DNA synthesis startup using enzymes instead of chemicals to write DNA — announced in March the successful de novo synthesis of a 1005-mer, the world’s longest synthetic oligonucleotide, encoding a key part of the AAV vector used for developing gene therapies. And that’s just the beginning. Co-founder Dan Lin-Arlow will be giving another lightning talk at this year’s 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 Bioscience’s 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.

Incapable of replicating on their own, viruses must hijack other organisms, like bacteria, to continue their existence. Little wonder, then, that bacteria had to develop ways to fight back.

Among them is CRISPR, a kind of an immune system that keeps DNA records of previous infections and then uses a protein called Cas to attack viruses that show up again. When Cas reaches a targeted virus, it cleaves the viral DNA, protecting the bacteria from infection.

Researchers have harnessed that targeted, DNA-snipping ability as a gene editing tool for all kinds of organisms. CRISPR can now be found in a variety of fields doing a variety of jobs, from helping to fight sickle cell and high cholesterol in humans to gene editing animals and crops. It’s proven to be an amazingly versatile tool.

Exceptionally well-preserved fossils from the Cambrian period have helped fill a gap in our understanding of the origin and evolution of major animal groups alive today.

A new analysis of fossils belonging to an extinct invertebrate called Rotadiscus grandis have helped place this species in the animal tree of life, revealing how some characteristics of living species may have evolved independently rather than originating in a single common ancestor.

Half a billion years ago, an unusual-looking animal crawled over the sea floor, using tentacles to pick up food particles along the way.

Some GPU cryptomining outfits, having survived a bleak winter of discontent, have started to grasp AI acceleration opportunities.
