Plant-Based Startup’s 3D-Printed Steaks Set For Mass Market

Novameat is eyeing the expansion of its plant-based 3D-printed steaks since launching its cutting-edge technology three years ago.


A Spanish start-up creating 3D-printed plant-based steaks is eyeing an expansion onto the mass market.

It follows a successful launch last year, and the company has plans to produce 500kg of the vegan meat products per hour.

Since developing the cutting-edge biotechnology in 2018, the company revealed scaling production goals. It hopes to soon offer products to restaurants across Spain.

New nanotech will enable a ‘healthy’ electric current production inside the human body

The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body’s tissues. The researchers believe that this new nanotechnology has many potential applications in medicine, including harvesting clean energy to operate devices implanted in the body (such as pacemakers) through the body’s natural movements, eliminating the need for batteries.


The study was led by Prof. Ehud Gazit of the Shmunis School of Biomedicine and Cancer Research at the Wise Faculty of Life Sciences, the Department of Materials Science and Engineering at the Fleischman Faculty of Engineering and the Center for Nanoscience and Nanotechnology, along with his lab team, Dr. Santu Bera and Dr. Wei Ji.

Also taking part in the study were researchers from the Weizmann Institute and a number of research institutes in Ireland, China and Australia. As a result of their findings, the researchers received two ERC-POC grants aimed at using the scientific research from the ERC grant that Gazit had previously won for applied technology. The research was published in the prestigious journal Nature Communications.

Prof. Gazit, who is also Founding Director of the Blavatnik Center for Drug Discovery, explains: Collagen is the most prevalent protein in the human body, constituting about 30% of all of the proteins in our body. It is a biological material with a helical structure and a variety of important physical properties, such as mechanical strength and flexibility, which are useful in many applications. However, because the collagen molecule itself is large and complex, researchers have long been looking for a minimalistic, short and simple molecule that is based on collagen and exhibits similar properties. About a year and a half ago, in the journal Nature Materials, our group published a study in which we used nanotechnological means to engineer a new biological material that meets these requirements.

Pandemic Wave of Automation May Be Bad News for Workers

Such changes, multiplied across thousands of businesses in dozens of industries, could significantly change workers’ prospects. Professor Warman, the Canadian economist, said technologies developed for one purpose tend to spread to similar tasks, which could make it hard for workers harmed by automation to shift to another occupation or industry.


The need for social distancing led restaurants and grocery stores to seek technological help. That may improve productivity, but could also cost jobs.

After 140 Years, Biologists Have ‘Resurrected’ The Genus of These Weird Yellow Cells

😀 This could to more complex organisms being resurrected.


Deep in the tissues of sea anemones, corals, and jellyfish are strange yellow cells which are genetically distinct from the marine animals.

More than a century after these cells were first assigned a now forgotten genus, a new paper has resurrected the name and described six new species from around the world.

“Because our team comprises scientists from seven countries, we were able to collect all of these samples, and some during the global pandemic,” said lead author of the study, biologist Todd LaJeunesse from Penn State University.

The U.S. Military Is Testing a Pill That Could Delay Aging

😀


U.S. Special Operations Command (SOCOM), the organization that administers America’s Spec Ops forces, says it will soon start clinical trials of an “anti-aging pill” that could halt some naturally degenerative effects of aging.

“We have completed pre-clinical safety and dosing studies in anticipation of follow-on performance testing in fiscal year 2022,” Navy Commander Tim Hawkins, a SOCOM spokesperson, told Breaking Defense.

Inherited memories of a chromosomal site

Most biological traits are inherited via genes, but there are exceptions to this rule. Two teams from the University of Geneva (UNIGE) have been investigating the location of centromeres—specific sites on chromosomes that are essential for cell division. They found that in the small worm Caenorhabiditis elegans, the transmission of the correct location of these sites to the offspring is not mediated by genes, but by an epigenetic memory mechanism. These results have been published in the journal PLOS Biology.

Living organisms, from humans to microscopic worms, inherit physical and sometimes behavioral traits from their parents. The transmission of biological traits is usually mediated by DNA which is replicated at each cell division and contains the genes. However, some characteristics can be transmitted from one generation to the next independently of genes: these are epigenetic phenomena.

Self-powered implantable device stimulates fast bone healing, then disappears without a trace

In 2017, Green Bay Packers quarterback Aaron Rodgers broke his right collarbone in a game against the Minnesota Vikings. Typically, it takes about 12 weeks for a collarbone to fully heal, but by mid-December fans and commentators were hoping the three-time MVP might recover early and save a losing season.

So did Xudong Wang, a professor of materials science and engineering at the University of Wisconsin-Madison and an expert in creating thin, movement-powered medical devices. “I started wondering if we could provide a new solution to bring athletes back to the field quicker than ever,” Wang says.

Researchers know that electricity can help speed up bone healing, but “zapping” fractures has never really caught on, since it requires surgically implanting and removing electrodes powered by an external source.

A major update of that same electrostimulation concept, Wang’s latest invention didn’t come in time to help the 2017 Packers–however, it may help many others by making electrostimulation a much more convenient option to speed up bone healing.

His thin, flexible device is self-powered, implantable and bioresorbable, so once the bone is knitted back together, the device’s components dissolve within the body.

Wang and his collaborators, including Weibo Cai, a UW-Madison professor of radiology and medical physics, described the new device today (July 5, 2021) in the journal Proceedings of the National Academy of Sciences.

Common Mechanism Underlies Some Behavioral Traits Seen in Autism and Schizophrenia

The researchers also showed that they could restore normal cognitive function in mice with these genetic mutations by artificially turning down hyperactivity in neurons of the AD thalamus. The approach they used, chemogenetics, is not yet approved for use in humans. However, it may be possible to target this circuit in other ways, the researchers say.


Summary: Certain genes that are mutated or missing in those with schizophrenia and autism cause similar dysfunction in neural networks within the thalamus.

Many neurodevelopmental disorders share similar symptoms, such as learning disabilities or attention deficits. A new study from MIT has uncovered a common neural mechanism for a type of cognitive impairment seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for each condition.

In a study of mice, the researchers found that certain genes that are mutated or missing in some people with those disorders cause similar dysfunctions in a neural circuit in the thalamus. If scientists could develop drugs that target this circuit, they could be used to treat people who have different disorders with common behavioral symptoms, the researchers say.
