In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize the cell’s own energy, and thereby enable hydrogen gas to be produced from solar energy.

Hydrogen gas has long been noted as a promising energy carrier, but its production is still dependent on fossil raw materials. Renewable hydrogen gas can be extracted from water, but as yet the systems for doing so have limitations.

In the new article, published in the journal Energy and Environmental Science, an interdisciplinary European research group led by Uppsala University scientists describe how artificial enzymes convert solar energy into hydrogen gas. This entirely new method has been developed at the University in the past few years. The technique is based on photosynthetic microorganisms with genetically inserted enzymes that are combined with synthetic compounds produced in the laboratory. Synthetic biology has been combined with synthetic chemistry to design and create custom artificial enzymes inside living organisms.

The universe is filled with uncountable amounts of mystery, discovery, opportunity, experiences, marvels and more. So, let’s not die if we don’t have to.

It’s much harder to make the case that radical longevity cannot be engineered into our biology than that it can. Humanity engineers cells in countless ways all the time now, and our knowledge, capability and tools keep growing exponentially.

Now, a mainstream amount of demand to create a bustling global industry of life extension R&D is the only thing standing between you and the ability to live indefinitely.” — Eric Schulke

Fifteen thousand years worth of Netflix are watched every day. Fifteen billion dollars are spent on the Super Bowl and fifteen billion dollars are spent on Valentine’s day. Those aren’t bad things but we need some perspective. Survival is humanity’s main and oldest occupation. We have what it takes to survive if we pay attention and get with the program.

To rapidly detect the presence of E. coli in drinking water, Cornell University food scientists now can employ a bacteriophage — a genetically engineered virus — in a test used in hard-to-reach areas around the world.

A recent open-access mouse study published by Xi’an Institute of Tissue Engineering and Regenerative Medicine scientists in the journal Bone Research describes how the ALPL gene affects bone aging and suggests that metformin might constitute a viable therapeutic option to prevent it [1].

Study abstract

Mutations in the liver/bone/kidney alkaline phosphatase (Alpl) gene cause hypophosphatasia (HPP) and early-onset bone dysplasia, suggesting that this gene is a key factor in human bone development. However, how and where Alpl acts in bone ageing is largely unknown. Here, we determined that ablation of Alpl induces prototypical premature bone ageing characteristics, including bone mass loss and marrow fat gain coupled with elevated expression of p16INK4A (p16) and p53 due to senescence and impaired differentiation in mesenchymal stem cells (MSCs). Mechanistically, Alpl deficiency in MSCs enhances ATP release and reduces ATP hydrolysis. Then, the excessive extracellular ATP is, in turn, internalized by MSCs and causes an elevation in the intracellular ATP level, which consequently inactivates the AMPKα pathway and contributes to the cell fate switch of MSCs.

Biohacking for cures: what you need to know.

Highly specialized cartilage is characteristically avascular and non-neural in composition with low cell numbers in an aliphatic environment. Despite its apparent simplicity, bioengineering regenerative hyaline cartilage in a form effective for implantation remains challenging in musculoskeletal tissue engineering. Existing surgical techniques including autologous chondrocyte implantation (ACI) and matrix-induced autologous chondrocyte implantation (MACI) are considered superior to self-repair induction techniques. However, both MACI and ACI are complex, multistage procedures that require a double operation; first for surgical excision of native cartilage, followed by expansion of adult chondrocytes in vitro prior to implantation by a second operation.

Regenerating robust articular hyaline-like cartilage is a key priority in musculoskeletal tissue engineering to prevent cost-intensive degenerative osteoarthritis that limits the quality of life in global healthcare. Integrating mesenchymal stem cells and 3D printing technologies has shown significant promise in bone tissue engineering– although the key challenge remains in transferring the bench-based technology to the operating room for real-time applications. To tackle this, a team of Australian orthopedic surgeons and bioengineers collaboratively proposed an in situ additive manufacturing technique for effective cartilage regeneration. The handheld engineered extrusion device known as the BioPen offers an advanced, co-axial extrusion strategy to deposit cells embedded in a hydrogel material within a surgical setting.

Researchers have used gene editing to completely eliminate populations of mosquitoes in the lab.

The team tested their technique on the mosquito Anopheles gambiae, which transmits malaria.

They altered part of a gene called doublesex, which determines whether an individual mosquito develops as a male or as a female.
