Imagine doctors being able to predict how a disease might progress in your body based on your genetic makeup, or which treatments would be most effective for you.

This research could bring us one step closer to that reality.

To sum it all up, this new research is shaking up how we think about evolution. Instead of seeing it as a series of random events, the study suggests there’s a level of predictability influenced by gene families and genetic history.

Bioengineers propose “electro-agriculture,” a method that replaces photosynthesis with a solar-powered reaction converting CO₂ into acetate, potentially reducing U.S. agricultural land needs by 94% and supporting controlled indoor farming.

Initial experiments focus on genetically modified acetate-consuming plants like tomatoes and lettuce, with potential future applications in space agriculture.

Potential therapies could include precise genetic targeting of the GLUT4 pathway or dietary modifications to fine-tune glucose levels, ensuring an optimal environment for neurogenesis.

Stanford research uncovers glucose’s role in boosting neurogenesis, offering insights into brain aging interventions.

Cirrhosis, hepatitis infection and other causes can trigger liver fibrosis—a potentially lethal stiffening of tissue that, once begun, is irreversible. For many patients, a liver transplant is their only hope. However, research at Cedars-Sinai in Los Angeles may offer patients a glimmer of hope. Scientists there say they’ve successfully reversed liver fibrosis in mice.

Reporting in the journal Nature Communications, the team say they’ve discovered a genetic pathway that, if blocked, might bring fibrosis to a halt.

The three genes involved in this fibrotic process are called FOXM1, MAT2A and MAT2B.

Discovery advances development of new therapeutic options for cancer and other diseases. A research team led by the University of California, Irvine has engineered an efficient new enzyme that can produce a synthetic genetic material called threose nucleic acid. The ability to synthesize artificial chains of TNA, which is inherently more stable than DNA, advances the discovery of potentially more powerful, precise therapeutic options to treat cancer and autoimmune, metabolic and infectious diseases.

A paper recently published in Nature Catalysis describes how the team created an enzyme called 10–92 that achieves faithful and fast TNA synthesis, overcoming key challenges in previous enzyme design strategies.

Inching ever closer to the capability of natural DNA synthesis, the 10–92 TNA polymerase facilitates the development of future TNA drugs.

CRISPR is a way off being using in human treatment – but a new discovery could unlock its potential. Here’s what’s new.

This level of precision could be a game-changer for therapies that require gene expression in one specific tissue, without impacting others.

By providing more control over where and when genes are activated, these AI-designed CREs could potentially be used in a variety of therapeutic applications, from treating genetic diseases to optimizing tissue regeneration.

As this AI-powered approach to designing CREs matures, the possibilities are vast. Beyond basic research, these synthetic DNA switches could be employed in biomanufacturing or to develop advanced treatments for a range of conditions, offering more effective ways to manipulate genes with unprecedented precision.

The acetate would then be used to feed plants that are grown hydroponically. The method could also be used to grow other food-producing organisms, since acetate is naturally used by mushrooms, yeast, and algae.

“The whole point of this new process to try to boost the efficiency of photosynthesis,” says senior author Feng Jiao, an electrochemist at Washington University in St. Louis. “Right now, we are at about 4% efficiency, which is already four times higher than for photosynthesis, and because everything is more efficient with this method, the CO₂ footprint associated with the production of food becomes much smaller.”

To genetically engineer acetate-eating plants, the researchers are taking advantage of a metabolic pathway that germinating plants use to break down food stored in their seeds. This pathway is switched off once plants become capable of photosynthesis, but switching it back on would enable them to use acetate as a source of energy and carbon.
