Synthetic Biology Enables Microbes To Build Muscle Fibers That Are Tougher Than Kevlar

Posted by in categories: bioengineering, biological

No animals were harmed in the production of the synthetic muscle fibers, which are tougher than Kevlar.

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even Kevlar, then why not?

Don’t worry, this muscle could be produced without harming a single animal.

DNA repair using CRISPR will be key to future space exploration

Posted by in categories: bioengineering, biotech/medical

DNA damage by radiation is a concern for space travelers. New experiments on the ISS show that CRISPR gene editing tools can function in space and can potentially be used to mitigate these effects.

Studying DNA repair is key to future space exploration, which could expose humans to risk of DNA damage caused by radiation. Conditions in space also could affect the way the body repairs such damage, potentially compounding that risk.

Synthetic biology enables microbes to build muscle

Posted by in categories: bioengineering, biological, chemistry

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even Kevlar, then why not?

Don’t worry, this muscle could be produced without harming a single animal.

Researchers at the McKelvey School of Engineering at Washington University in St. Louis have developed a synthetic chemistry approach to polymerize proteins inside of engineered microbes. This enabled the microbes to produce the high molecular weight muscle protein, titin, which was then spun into fibers.

Conversations with Maya: Ray Kurzweil

Posted by in categories: bioengineering, Ray Kurzweil, singularity

Maya Ajmera, President & CEO of Society for Science & the Public and Publisher of Science News, chatted with Ray Kurzweil, an alumnus of the Science Talent Search and a renowned inventor and futurist. Kurzweil also has written five best-selling books, is Cofounder and Chancellor of Singularity University and is a Director of Engineering at Google. We are thrilled to share an edited summary of their conversation.

You are an alum of the1965Science Talent Search. How did the competition impact your life, and are there any particular moments that still stand out for you?

The Westinghouse Science Talent Search was the first time I was recognized nationally. President Johnson had just been elected and we met him at the White House. He told us his goal was that our generation would never see the horrors of war.

A Natural Protein to ‘SEND’ Gene Editing Cargo to Cells

Posted by in categories: bioengineering, biotech/medical

One of the most difficult aspects of gene therapy might be ensuring that it gets into the right cells safely so it can have a therapeutic effect. Researchers have now created a new way to deliver various types of RNA cargo to cells, which utilizes one of the human body’s natural proteins to create particles that can bind to RNA. This approach, called SEND, may help reduce any immune response that would be mounted against a gene therapy. The work has been reported in Science.

Current delivery systems are not efficient, may integrate their cargo improperly, and can cause serious immune reactions. “The biomedical community has been developing powerful molecular therapeutics, but delivering them to cells in a precise and efficient way is challenging,” said senior study author Feng Zhang, Ph.D., a core institute member at the Broad Institute, among many other appointments. “SEND has the potential to overcome these challenges.”

Fundamental mechanics help increase battery storage capacity and lifespan

Posted by in categories: bioengineering, energy, physics, sustainability, transportation

Batteries are widely used in everyday applications like powering electric vehicles, electronic gadgets and are promising candidates for sustainable energy storage. However, as you’ve likely noticed with daily charging of batteries, their functionality drops off over time. Eventually, we need to replace these batteries, which is not only expensive but also depletes the rare earth elements used in making them.

A key factor in life reduction is the degradation of a battery’s structural integrity. To discourage structural degradation, a team of researchers from USC Viterbi School of Engineering are hoping to introduce “stretch” into battery materials so they can be cycled repeatedly without structural fatigue. This research was led by Ananya Renuka-Balakrishna, WiSE Gabilan Assistant Professor of Aerospace and Mechanical Engineering, and USC Viterbi Ph.D candidate, Delin Zhang, as well as Brown University researchers from Professor Brian Sheldon’s group. Their work was published in the Journal of Mechanics and Physics of Solids.

A typical battery works through a repetitive cycle of inserting and extracting Li-ions from electrodes, Zhang said. This insertion and extraction expands and compresses the lattices. These volume shifts create microcracks, fractures and defects over time.

Discovery that TRPV4 gene regulates cartilage growth might yield future therapies for joint repair

Posted by in categories: bioengineering, biotech/medical

New information from a study reported in Stem Cells might result in more effective treatments for osteoarthritis and other cartilage diseases, as well as hereditary disorders affecting cartilage development. Their findings might also point to a new way to accelerate stem cell differentiation for bioengineering cartilage, the researchers say.

The Rise of Man: What Was Our Ultimate Success Formula As a Species?

Posted by in categories: bioengineering, biotech/medical, evolution, food, genetics, internet

What we’ll soon see is the ultimate self-directed evolution fueled forward by gene editing, genetic engineering, reproduction assisted technology, neuro-engineering, mind uploading and creation of artificial life. Our success as a technological species essentially created what might be called our species-specific “success formula.” We devised tools and instruments, created new methodologies and processes, and readjusted ecological niches to suit our needs. And our technology shaped us back by shaping our minds. In a very real sense, we have co-evolved with our technology. As an animal species among many other species competing for survival, this was our unique passage to success.

Gene Editing Used to Block Mosquitos’ Ability to Identify Targets

Posted by in categories: bioengineering, biotech/medical, food

Craig Montell is a professor at the University of California, Santa Barbara, who helped lead the research. He said in a statement that by removing the two eye receptors, the team was able to “eliminate CO2-induced target recognition without causing blindness.”


Female Aedes aegypti search out blood meals in humans to develop eggs. They use several different senses to find those meals. One of the main identifying tools is the smell of carbon dioxide (CO2). When a human breathes out CO2, the mosquitoes become more active and begin looking for targets to bite.

The research team said this search generally begins with the mosquito flying toward the direction of the released CO2. When seeking out targets, the insects search for dark objects. Once the mosquitoes are within close range, they can also sense heat from skin and additional skin smells to help guide them to a human.
