It worked. Working with mice, they were able to reverse the disease symptoms of kidney disease, type 1 diabetes, and a form of muscular dystrophy. In the mouse with kidney disease, for example, they turned on two genes associated with kidney function and saw the kidney function improved.

The unassumingly named CRISPR/Cas9 is a technology that stands to remake the world as we know it. By allowing scientists to more easily than ever cut and paste all those As, Cs, Ts, and Gs that encode all the world’s living things, for one thing, it could one day cure many devastating diseases.

All that power, though, comes with one pretty sizable caveat: Sometimes CRISPR doesn’t work quite like we expect it to. While the scientific establishment is still embroiled in a debate over just how serious the problem is, CRISPR sometimes causes off-target effects. And for scientists doing gene editing on human patients, those mutations could wind up inadvertently causing problems like tumors or genetic disease. Yikes.

‘UN diplomats confirmed that the new email release would worsen the “bad name” of gene drives in some circles. “Many countries [will] have concerns when this technology comes from DARPA, a US military science agency,” one said.‘.

Cutting-edge gene editing tools such as Crispr-Cas9 work by using a synthetic ribonucleic acid (RNA) to cut into DNA strands and then insert, alter or remove targeted traits. These might, for example, distort the sex-ratio of mosquitoes to effectively wipe out malarial populations.

Some UN experts, though, worry about unintended consequences. One told the Guardian: “You may be able to remove viruses or the entire mosquito population, but that may also have downstream ecological effects on species that depend on them.”

Summary: (Video) A short animation from the journal Nature demonstrates revolutionary new additions to the CRISPR toolbox some call CRISPR 2.0. Scroll down for video. [This article first appeared on LongevityFacts. Follow us on Reddit | Google+ | Facebook. Author: Brady Hartman.]

Techniques to modify DNA in the genome have existed for several decades, and the original CRISPR-Cas9, called CRISPR 1.0, brought an era of faster, cheaper, and more efficient gene editing tools. A short video from the journal Nature shows you how scientists have revolutionized the original CRISPR-Cas9 system, significantly expanded its toolbox, creating a more powerful set of tools some call CRISPR 2.0. Genetic engineers have discovered how to make CRISPR perform new tricks such as improved gene editing, turning genes on and off, and making genes glow for research.

What are gene editing and crispr-cas9?

Summary: Will gene drive wipe out malaria-causing mosquitoes, or will the genetic technology that ‘spreads like wildfire’ cause a catastrophe? Gene drive raises hopes and fears as a team of scientists funded by the Bill & Melinda Gates Foundation are using it to wipe out the mosquitoes that carry malaria, to eradicate the disease. [This article first appeared on LongevityFacts. Follow us on Reddit | Google+ | Facebook. Author: Brady Hartman.]

In a basement lab at the Imperial College London (ICL), a group of researchers led by Andrew Hammond are on a mission to wipe out malaria. The scientists are funded by the Bill & Melinda Gates Foundation and are using a technology called gene drive – a souped-up form of genetic engineering designed to wipe out the mosquitoes that carry the disease.

The lab contains cages of mosquitoes modified with the gene drive, along with an additional gene that makes their eyes and other body parts glow red under laser light.

Summary: Can a gene fuel obesity? Variants of a gene called ‘ankyrin-B’ – a gene carried by millions of Americans – could cause individuals to put on pounds through no fault of their own. [This article first appeared on LongevityFacts. Follow us on Reddit | Google+ | Facebook. Author: Brady Hartman]

We often attribute obesity to eating too much and exercising too little. However, the evidence is growing that at least some of our weight gain is predetermined by our genes. And if a simple genetic variant causes weight gain, then it’s a prime target for gene editing.

New research from the University of North Carolina suggests that variants in a gene called ankyrin-B, a gene carried by millions of Americans, could cause individuals to gain weight through no fault of their own.

Since the dawn of medicine, aging has been doctors’ foremost challenge. Three unsuccessful approaches to conquering it have failed: treating components of age-related ill health as curable diseases, extrapolating from differences between species in the rate of aging, and emulating the life extension that famine elicits in short-lived species. SENS Research Foundation is spearheading the fourth age of anti-aging research: the repair of age-related damage, that is, rejuvenation biotechnology.

The Strategies for Engineered Negligible Senescence (SENS) approach was first proposed in 2002. “Senescence,” here, refers to the actuarial phenomenon—the trend that individuals within a population suffer from an increasing morbidity and mortality rate in (typically exponential) relation to their chronological age. “Negligible” is used in a statistical sense: we consider a level of senescence negligible if no age-related contribution to mortality is statistically demonstrable within a population, given the “background noise” of age-independent mortality (such as unfortunate encounters with motor vehicles). Finally, by “Engineered,” we indicate that this state is achieved by the deliberate application of biomedical therapies, and is not the normal situation. The goal of SENSE is thus unambiguously defined; we seek methods to convert a population experiencing a non-negligible level of senescence into one experiencing a negligible level.

Scientists have expanded the building blocks of DNA to create a stable semi-synthetic organism that can produce biological compounds entirely new to nature.

The DNA that makes up essentially all living things on Earth consists of arrangements of four basic nucleotides, but the new life-form developed by researchers in the US makes use of six – and that’s where things get interesting.

The semi-synthetic organism (SSO) engineered by a team at the Scripps Research Institute in California is made from the same four regular nucleobases as you and I – adenine (A), cytosine ©, guanine (G), and thymine (T) – but it’s also got two unnatural nucleotides to call upon.

The sense of touch is often taken for granted. For someone without a limb or hand, losing that sense of touch can be devastating. While highly sophisticated prostheses with complex moving fingers and joints are available to mimic almost every hand motion, they remain frustratingly difficult and unnatural for the user. This is largely because they lack the tactile experience that guides every movement. This void in sensation results in limited use or abandonment of these very expensive artificial devices. So why not make a prosthesis that can actually “feel” its environment?

That is exactly what an interdisciplinary team of scientists from Florida Atlantic University and the University of Utah School of Medicine aims to do. They are developing a first-of-its-kind bioengineered robotic hand that will grow and adapt to its environment. This “living” robot will have its own peripheral nervous system directly linking robotic sensors and actuators. FAU’s College of Engineering and Computer Science is leading the multidisciplinary team that has received a four-year, $1.3 million grant from the National Institute of Biomedical Imaging and Bioengineering of the National Institutes of Health for a project titled “Virtual Neuroprosthesis: Restoring Autonomy to People Suffering from Neurotrauma.”

For the first time ever, scientists have attempted to cure a person’s disease by editing a gene inside the body.

Scientists used an IV to inject a patient with billions of copies of a corrective gene and a genetic tool to cut his DNA in a specific spot. “We cut your DNA, open it up, insert a gene, stitch it back up.”

Scientists have edited people’s genes in the past, but that work involved altering cells inside a lab and then returning them to the body, whereas the latest experiment was performed inside a person’s body.
