New DNA computer assesses water quality
Posted by Saúl Morales Rodriguéz in categories: bioengineering, biotech/medical, computing, genetics
Northwestern University synthetic biologists have developed a low-cost, easy-to-use, hand-held device that can let users know—within mere minutes—if their water is safe to drink.
The new device works by using powerful and programmable genetic networks, which mimic electronic circuits, to perform a range of logic functions.
Among the DNA-based circuits, for example, the researchers engineered cell-free molecules into an analog-to-digital converter (ADC), a ubiquitous circuit type found in nearly all electronic devices. In the water-quality device, the ADC circuit processes an analog input (contaminants) and generates a digital output (a visual signal to inform the user).

What is stopping gene-edited food from saving our planet?
Posted by Gemechu Taye in categories: bioengineering, biotech/medical, food, genetics
Not science, apparentlyLast month, a Ph.D. student at the Hebrew University of Jerusalem breed a new strain of ‘supercharged’ lettuce that expanded its vitamin C and beta carotene content by 800 percent and 70 percent respectively.
Research Interests.
Genomic/metabolomic/proteomic approaches for identification of novel (regulatory and biosynthetic) aroma genes.

Scientists create a global repository for cell engineering
Posted by Jose Ruben Rodriguez Fuentes in categories: bioengineering, genetics
A cloud-based repository that creates a digital fingerprint of engineered microorganisms has been successfully trialed.
An international team led by Newcastle University has launched CellRepo, a species and strain database that uses cell barcodes to monitor and track engineered organisms. Reported in a new study in the journal Nature Communications, the database keeps track and organizes the digital data produced during cell engineering. It also molecularly links that data to the associated living samples.
Available globally, this resource supports international collaboration and has significant safety advantages, such as limiting the impact of deliberately or accidentally released genetically modified microorganisms by enabling faster tracing of organisms lab of origin and design details.

Dr. Marvin Minsky — Facing the Future

As soon as we understand how the human brain works, we should be able to make functional copies of our minds out of other materials. Given that everything is made of atoms, if you make a machine, in some sense it is made of the same kinds of materials as brains are made but organized either in very different ways or fundamentally the same ways.

The Lifeboat Foundation is a nonprofit nongovernmental organization dedicated to encouraging scientific advancements while helping humanity survive existential risks and possible misuse of increasingly powerful technologies, including genetic engineering, nanotechnology, and robotics/AI, as we move towards the Singularity.
Lifeboat Foundation is pursuing a variety of options, including helping to accelerate the development of technologies to defend humanity, such as new methods to combat viruses, effective nanotechnological defensive strategies, and even self-sustaining space colonies in case the other defensive strategies fail.

After First Pig-to-Human Heart Transplant, Scientists Aim to Make It Routine
Posted by Dan Breeden in categories: bioengineering, biotech/medical, genetics
“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” said Bennett.
The heart was provided by Revivicor, a company based in Virginia that has been engineering pig organs for roughly two decades. In several experiments for pig-to-baboon transplants, the organs survived up to nine months, until the animals passed away due to a lung infection unrelated to the transplant.
Overall, the heart had 10 hefty genetic edits. Three of them wiped out sugar molecules on the outside of cells that provoke an immune response. Six bolstered the chance of the human host accepting the heart—amping up an anti-inflammatory response, preventing blood vessel damage, and dampening any antibodies against the organ. Finally, the last edit limited the pig heart’s size. Although it generally matched the size of a human heart, the team wanted to prevent the pig organ from overgrowth inside Bennett’s chest once it was transplanted—something they previously noticed happened in baboons.

New Gene Sequencing Method Cuts Cost and Is Five Times Faster, Study Says
Posted by Gemechu Taye in categories: bioengineering, biotech/medical, genetics
And it took less than a full workday. Stanford Medicine scientists and their collaborators have engineered a new genome sequencing technique that can diagnose rare genetic diseases in an average of eight hours. This is a record-breaking time frame that is leap and bounds ahead of other current advanced technologies.
Gene sequencing is crucial to advancing science! Check out why cutting time and cost is key.
