Synthetic biology used to limit bacterial growth and coordinate drug release

Beautiful.


Researchers at the University of California San Diego and the Massachusetts Institute of Technology (MIT) have come up with a strategy for using synthetic biology in therapeutics. The approach enables continual production and release of drugs at disease sites in mice while simultaneously limiting the size, over time, of the populations of bacteria engineered to produce the drugs. The findings are published in the July 20 online issue of Nature.

UC San Diego researchers led by Jeff Hasty, a professor of bioengineering and biology, engineered a clinically relevant bacterium to produce and then self-destruct and release the drugs at the site of tumors. The team then transferred the bacterial therapy to their MIT collaborators for testing in an animal model of colorectal metastasis. The design of the therapy represents a culmination of four previous Nature papers from the UC San Diego group that describe the systematic development of engineered genetic clocks and synchronization. Over the years, the researchers have employed a broad approach that spans the scales of synthetic biology.

The new study offers a therapeutic approach that minimizes damage to surrounding cells.

Musings on Synthetic Biology and Crop Disease Resistance

Why Plants? Part III – Rise of The Plant Machines by Orlando de Lange.

Everyone talks about the rise of the robots. What about the rise of the “Vegetation/ Plant Machines?”


In part 3 of our series on plant synthetic biology, Orlando de Lange (@SeaGreenODL) of The New Leaf blog introduces how synbio approaches are being used to develop novel disease resistant crops, overcoming some of the challenges faced by monoculture farming.

The King’s man

In 1970 an unassuming American man with greying hair and large spectacles stood before the King of Norway and was awarded the Nobel Peace Prize. This prize of international renown is set aside for individuals who have made the greatest possible contribution to peace among nations. Who was the king’s man in 1970? A president, a diplomat, a great writer, perhaps? No, he was crop scientist and plant breeder Norman Borlaug, founding father of the Green Revolution.

A new tracking and quantification tool for single cells

New method for tracking single cells; definitely could be interesting for genetic mutation research such as cancer, Parkinson, etc.


As far as the scientists are concerned, the new possibilities that these programs offer should be available to as many researchers around the world as possible. Therefore the software is freely available, and can be downloaded from the following link: http://www.bsse.ethz.ch/csd/software/ttt-and-qtfy.html

Technical obstacles were removed as far as possible. “Our focus was on making the application also available to researchers who do not have background IT know-how,” Schroeder explains. And the application appears to work well: Two high-ranking publications can be traced back to the spyware for cells.

Law enforcement and the Dark Web, a never ending battle

Dark Net v. Law Enforcement — who is winning and who is struggling.


The Dark web is a privileged place for cyber criminals that, under specific conditions, could operate in anonymity.

The United Nation’s Office on Drugs and Crime (UNODC) has published its annual report that contains a specific mention to the illicit trade of goods and drugs in this hidden part of the web.

The crooks seem to be one step ahead many countries’ law enforcement agencies that in many cases are not able to target black markets in the dark web.

Matching Fund Donors Sought for SENS Universal Cancer Therapy Crowdfunding

SENS has a fund match for its current campaign on lifespan.io, if you are concerned about cancer like me and you want to help directly fund a lab working on solutions please think about donating. smile


There is a month left to go in the SENS crowdfunding campaign that aims to accelerate development of an important component of a universal cancer therapy, a way to block the mechanisms of telomere lengthening that every type of cancer depends upon. The SENS Research Foundation and Lifespan.io volunteers are looking for donors to put up matching funds of a few thousand dollars or more, in order to take that news and that inducement to a number of conferences and other events over the next few weeks. More than 150 people have donated to the campaign to date, and we’d like to triple that number in the next 30 days.

To start things off, I’ll offer up $2,000 of my own funds: the next $2,000 in donations to this SENS cancer research initiative will be matched dollar for dollar. That is a start, and if you can join in to help out, please contact me to let me know. Can you help to make a difference here?

With last week’s $10 million pledge in support of other portions of the SENS rejuvenation research portfolio, we can clearly see that grassroots fundraising works. It lights the way, and as we grow the community and show our determination, that success draws in larger donors. When this is amply demonstrated by the arrival of large amounts of new funding … well, that is precisely the time to pile on and keep up the good work. All major medical research non-profits have several tiers of fundraising, from grassroots to high net work philanthropy, and all of these tiers are essential: they can’t exist without one another. The SENS Research Foundation is transitioning to become a solid organization with a high end tier of fundraising to complement our efforts, and that couldn’t exist without the support of the grassroots. It is a sign that we are winning.

‘Living hip’ grown in lab genetically engineered to stop arthritis

Arthritis sufferers have been offered new hope after scientists grew a ‘living hip’ in the lab which not only replaces worn cartilage but stops painful joints returning.

Researchers in the US have used stem cells to grow cartilage in the exact shape of a hip joint while also genetically engineering the tissue to release anti-inflammatory molecules to fend off the return of arthritis.

The idea is to implant the perfectly shaped cartilage around the joint to extend its life before arthritis has caused too much damage to the bone.
