New gene editing tool reduces errors by nicking DNA not cutting (2 minute read)

While CRISPR is one of the most groundbreaking inventions of the century, it has a relatively high error rate that can produce potentially harmful mutations. Researchers from Germany have developed a tool that reduces errors by nicking DNA instead of cutting it. The tool makes two smaller cuts, one on each DNA strand, rather than slicing through the entire double strand of DNA. The new method is about as effective at making edits as conventional CRISPR and it significantly reduces on-target mutation errors.

Artificial Photosynthesis Can Produce Food in Complete Darkness (4 minute read)

A group of researchers has developed a way to create food without sunlight using artificial photosynthesis. The method involves converting carbon dioxide, electricity, and water into acetate, and then feeding the acetate to food-producing organisms in the dark to grow. It is up to 18% more efficient for some organisms. The method can be used to grow green algae, yeast, fungal mycelium, tomatoes, rice, and green peas. It could be used to grow crops in areas currently unsuitable for agriculture.

Life Has Been Found in a Low-Oxygen, Super-Salty, Sub-Zero Arctic Spring (3 minute read)

Scientists have discovered life in the extremely cold and salty waters of the Lost Hammer Spring in the Canadian Arctic. The microbes had adaptations that allowed them to thrive in water with temperatures of around minus five degrees Celsius, less than one part per million of dissolved oxygen, and around 24% salinity. They don't depend on organic material or oxygen to survive. Similar environments may exist on ocean worlds like Jupiter's moon Europa and Saturn's moon Enceladus.
