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 ...

Multiple modes for selectivity of transmembrane transport

LMU researchers utilized a biophysical approach to understand how bacterial import proteins bind and selectively convey their cargoes across membranes. The results reveal an unexpectedly wide variety of transfer mechanisms.

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 ...

Antimicrobial paints have a blind spot

Antimicrobial paints offer the promise of extra protection against bacteria. But Northwestern University researchers caution that these paints might be doing more harm than good.

Bacterial mix helps predict future change

A controlled, laboratory approach, along with computer simulations, has helped KAUST researchers to show that bacterial communities can homogenously disperse within aquatic ecosystems, even with slow-flowing water and the ...

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.

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 ...
