Killer mice; Yikes!
SCIENTISTS have turned mice from timid rodents to voracious predators by successfully flicking a genetic killer switch in their brains.

A woman was kept alive with no lungs for six days while she waited for a transplant in April last year.
It is thought to be the first operation of its kind in the world and she was kept alive with a small, artificial lung.
Melissa Benoit, who lives in Canada, had developed life-threatening complications as a result of her cystic fibrosis.

Growing organs in the lab is an enduring sci-fi trope, but as stem cell technology brings it ever closer to reality, scientists are beginning to contemplate the ethics governing disembodied human tissue.
So-called organoids have now been created from gut, kidney, pancreas, liver and even brain tissue. Growing these mini-organs has been made possible by advances in stem cell technology and the development of 3D support matrices that allow cells to develop just like they would in vivo.
Unlike simple tissue cultures, they exhibit important structural and functional properties of organs, and many believe they could dramatically accelerate research into human development and disease.

This biomedical advance has long been a dream and a quandary for scientists hoping to address a critical shortage of donor organs.
Every ten minutes, a person is added to the national waiting list for organ transplants. And every day, 22 people on that list die without the organ they need. What if, rather than relying on a generous donor, you could grow a custom organ inside an animal instead?

In Brief:
- A drug seems to be showing signs of reversing the effects of aging in dogs and mice. Studies are being conducted on the effectiveness in humans.
- The drug has some major side effects linked to it and there is no guarantee it will be as effective in humans.
Aging is a spectre we all must face one day…but is this the way that it will always be? Medical researchers hope to delay or even reverse the onset of aging, and some are already claiming that they’ve made inroads to immortality.

Researchers at EPFL’s Laboratory of Photonic Materials and Fibre Devices, which is run by Fabien Sorin, have come up with a simple and innovative technique for drawing or imprinting complex, nanometric patterns on hollow polymer fibers. Their work has been published in Advanced Functional Materials.
The potential applications of this breakthrough are numerous. The imprinted designs could be used to impart certain optical effects on a fiber or make it water-resistant. They could also guide stem–cell growth in textured fiber channels or be used to break down the fiber at a specific location and point in time in order to release drugs as part of a smart bandage.

Intelligence Advanced Research Projects Activity (IARPA), the intelligence community’s research arm, will soon launch two programs designed to detect fake fingerprints and develop devices to collect fingerprint data without the aid of a human operator, according to a report by GCN.
The Odin program, which is scheduled to begin with four prime developers in early March, will develop detection technologies that can spot presentation attacks on biometric devices that attempt to spoof physical biometric samples, said Chris Boehnen, senior program manager at IARPA.
Boehnen said that prosthetic fingers, fake fingerprints made with wood glue and other tactics can dupe current fingerprint sensors.

Is Synbio the next big thing? Hmmm; depends. If we’re talking about ensuring that we have a solid foundation/ infrastructure (including platforms; etc.) on QC 1st then with the existing evolution and maturity of the fundamentals around Synbio as a 1st step; then accelerating the further maturity of Synbio into creating super humans and singularity? My answer is yes. If we’re not even considering that we need QC and just focused on Synbio only; my answer is No as QC will be required as a foundation for things like real Humanoid AI, cell circuited humans/ super humans, etc.
Why we might soon be buying silk, wood, and more fabricated out of genetic code.
