A biosynthetic dual-core cell computer

ETH researchers have integrated two CRISPR-Cas9-based core processors into human cells. This represents a huge step towards creating powerful biocomputers.

Fuel cells in bacteria

The exchange of nitrogen between the atmosphere and organic matter is crucial for life on Earth because nitrogen is a major component of essential molecules such as proteins and DNA. One major route for this exchange, discovered ...

Bacteria harness viruses to distinguish friend from foe

Bacterial cells that normally colonize our guts can distinguish themselves from other bacterial species using what's traditionally considered their enemy—a virus. Researchers report April 16 in the journal Cell Reports ...

In mice, feeding time influences the liver's biological clock

The timing of food intake is a major factor driving the rhythmic expression of most genes in the mouse liver, researchers report April 16th in the journal Cell Reports. The findings demonstrate that body-wide signals driven ...

Ginkgo seed extracts show antibacterial activity on skin pathogens

Extracts from the seeds of the Ginkgo biloba tree show antibacterial activity on pathogens that can cause skin infections such as acne, psoriasis, dermatitis and eczema, a study at Emory University finds. Frontiers in Microbiology ...

Cell-killing proteins suppress listeria without killing cells

New North Carolina State University research shows that key proteins known for their ability to prevent viral infections by inducing cell death can also block certain bacterial infections without triggering the death of the ...

Novel approach promises ready access to hard-to-study proteins

DNA and the genome, we know, provide the blueprint for life. But it is the proteins made according to the genome's instructions that are the nuts and bolts of living organisms, providing the molecular building blocks for ...
