Synthetic biology – the next big thing
Synthetic biology programming microorganisms to perform some new functions. Genes are made out of DNA; synthetic biology involves inserting synthetic genes that might not have existed before into yeast and reprogramming them to make a new chemistry or things not made naturally by biology. Each gene codes for an enzyme. One can program a new set of enzymes and convert them to intermediate products. If you go through five or even 15 steps, you can get a final product – a polymer, a new drug – creating a chemical factory inside a cell. This is much better than nanotechnology, because in synthetic biology, we get down to molecular size…
Prof. Joseph Jacobson, a leading physicist at the Massachusetts Institute of Technology, is not only the inventor of e-ink but also a mover in creating artificial DNA to eventually cure diseases.
Affordable genetic diagnostic technique for target DNA analysis developed
Professor Hyun-Gyu Park of the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST) has developed a technique to analyze various target DNAs using an aptamer, a DNA fragment that can recognize and bind to a specific protein or enzyme. This technique will allow the development of affordable genetic diagnosis for new bacteria or virus, such as Middle Ease Respiratory Syndrome (MERS). The research findings were published in the June issue of Chemical Communications, issued by the Royal Society of Chemistry in the United Kingdom. The paper was selected as a lead article of the journal.
This iPhone Accessory Replaces An Eye Doctor’s Office
A $4,000 iPhone gadget replaces a 30-pound, $20,000 machine, allowing eye doctors to visit patients they couldn’t reach before.
Bioviva is moving into telomerase rejuvenation therapy for Alzheimer’s!
Bioviva a Seattle, WA, based biotech is ambitiously moving forward with gene therapy in people to mitigate the consequences of aging. They have not gone for the low hanging fruit either, they are being supported by Maximum Life Foundation to raise enough to run a clinical trial to try to cure Alzheimer’s! They are targeting the supporting Microglia cells in the brain to help regenerate them and hopefully reverse the effects of the disease. A worthy cause if ever I saw one and if it works could translate to other similar conditions like Parkinson’s and ALS. Lets hope they can get this vital work underway. This will then be the first example of regenerative medicine in a person that treats the dysfunction of aging.
WHO: Trials show new Ebola vaccine is ‘highly effective’
A newly developed vaccine against the deadly Ebola virus being trialled in Guinea is “highly effective,” the World Health Organization said Friday.
Researchers build bacteria’s photosynthetic engine
“Furthermore, the chromatophore project marks a shift in computational biophysics from analyzing the individual cell parts (e.g., a single protein) to analyzing the specialized systems of the cell (e.g., hundreds of proteins working together to carry out an autonomous function). This is a significant step toward the long-term goal of simulating an entire living organism.”
Nearly all life on Earth depends on photosynthesis, the conversion of light energy into chemical energy. Oxygen-producing plants and cyanobacteria perfected this process 2.7 billion years ago. But the first photosynthetic organisms were likely single-celled purple bacteria that began absorbing near-infrared light and converting it to sulfur or sulfates about 3.4 billion years ago.
Researchers design first artificial ribosome
Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.
3D Printed Organs Are a Heartbeat Closer to Reality
Learn about the advancements of a robot that will save lives. The plan? It’s going to produce 3D printed organs and even a fully functional human heart.
Children With Prosthetics Could Soon Be Creating Their Own Lego Attachments
Imagine being able to snap a mechanical digger or a Star Wars spaceship onto the end of your arm. With the next level of prosthetic designs from Lego, this could soon be a playtime reality for kids with prosthetic limbs.
