As the year moves on and we look back at the achievements this year we would be remiss to not mention the fantastic result we got for the OncoSENS fundraiser hosted on Lifespan.io. We raised an amazing $72,002 for ALT cancer research thanks to the amazing supporters we have. Thank you to everyone who helped and donated to OncoSENS to make it another victory for SENS Research and for Science!

Luv it! Wait until we make the marriage of QC meets Synbio — QC for the infrastructure and communications, and Synbio makes us all connected.
Cambridge, MA (Scicasts) — Synthetic biology allows scientists to design genetic circuits that can be placed in cells, giving them new functions such as producing drugs or other useful molecules. However, as these circuits become more complex, the genetic components can interfere with each other, making it difficult to achieve more complicated functions.
MIT researchers have now demonstrated that these circuits can be isolated within individual synthetic “cells,” preventing them from disrupting each other. The researchers can also control communication between these cells, allowing for circuits or their products to be combined at specific times.
“It’s a way of having the power of multicomponent genetic cascades, along with the ability to build walls between them so they won’t have cross-talk. They won’t interfere with each other in the way they would if they were all put into a single cell or into a beaker,” says Edward Boyden, an associate professor of biological engineering and brain and cognitive sciences at MIT. Boyden is also a member of MIT’s Media Lab and McGovern Institute for Brain Research, and an HHMI-Simons Faculty Scholar.
Scientists have discovered an antibody produced by an HIV-positive patient that neutralises 98 percent of all HIV strains tested — including most of the strains that are resistant to other antibodies of the same class.
Due to HIV’s ability to rapidly respond to the body’s immune defences, an antibody that can block a wide range of strains has been very hard to come by. But now that we’ve found one, it could form the basis of a new vaccine against the virus.
Researchers from the US National Institutes of Health (NIH) found that the antibody, called NG, was able to maintain its ability to recognise the HIV virus, even as the virus morphed and broke away from it.
Lenses with a surface accuracy in the nanometer range are behind ever more accurate laser and optical systems. Manufacturers depend on ultra-precise optical and mechanical ablation processes, innovative coating processes and extremely accurate measuring technology to venture into these nano-worlds. The latest trends in optical manufacturing will be showcased by the world’s leading trade fair LASER World of PHOTONICS, from June 26–29, 2017 in Munich.

The diversity of lenses, their shapes, sizes and materials is growing all the time. Applications in non-visible wavelengths from x-rays and ultraviolet to the far infrared also require special optics, such as material processing using short pulse and ultrashort pulse lasers or imaging techniques in the medical and research fields and industrial quality control.
(Phys.org)—A team of researchers working at West China Hospital in Chengdu has for the first time injected CRISPR–Cas9 edited cells into a human test subject. Nature reports that the procedure occurred on October 28, and that thus far, the patient is doing “fine.”
Modified cells have been injected into human subjects before, of course, but using different techniques. CRISPR-Cas 9 is considered to be a more efficient approach. In this new effort, the researchers isolated immune cells retrieved from a blood sample, then used CRISPR-Cas9 to locate and disable the PD-1 protein in them, which prior research has shown slows an immune response by a cell. The idea is that disabling the protein will allow the immune system to put up more of a fight against tumor growth. The edited cells were placed in a container where they were fed and allowed to multiply—the entire collection was then gathered and injected into a patient suffering from a type of lung cancer that had not responded to any other treatment type.
The CRISPR technique involves using an RNA guide that binds to a particular DNA sequence and an enzyme (the Cas9 part) that can cut strands of DNA at preselected spots, allowing for removing strands or adding new ones.
Scientists have discovered a new way to edit DNA that could fix “broken genes” in the brain, cure previously incurable diseases and potentially even extend the human lifespan.
The breakthrough – described as a “holy grail” of genetics – was used to partially restore the sight of rats blinded by a condition which also affects humans.
Previously researchers were not able to make changes to DNA in eye, brain, heart and liver tissues.
Progress for heart disease!
For the first time, a new drug given along with a cholesterol-lowering statin medicine has proved able to shrink plaque that is clogging arteries, potentially giving a way to undo some of the damage of heart disease.
The difference was very small but doctors hope it will grow with longer treatment, and any reversal or stabilization of disease would be a win for patients and a long-sought goal.
The drug, Amgen Inc.’s Repatha, also drove LDL, or bad cholesterol, down to levels rarely if ever seen in people before. Heart patients are told to aim for below 70, but some study participants got as low as 15.
I said over a year ago that if the US will not do it China will. Whilst there was talk about a moratorium on CRISPR in the US the Chinese were forging ahead and taking steps to become a world leader in biotech. Well here we are, they have deployed CRISPR in humans for cancer and this is only the start. As George Church advocates, we should have appropriate engineering safety measures in place but we should push ahead and do these things.
The move by Chinese scientists could spark a biomedical duel between China and the United States.
