Solar energy becomes biofuel without solar cell

Solar energy turns into biofuel without solar cells

It seems like soon we will be able to replace fossil fuels with a carbo-neutral product created from solar energy, carbon dioxide, and water. Cyanobacteria,...
Yale researchers describe role of bacteria in drug response

Study reveals how gut bacteria could affect medical treatments

Have you ever wonder why a drug that works for someone else doesn't seem to work for you? It is still a quite mystery...

A new synthetic nanofactory inspired by nature

Bacteria across our planet contain nanometer-sized factories that do many different things. Some make nutrients, others isolate toxic materials that could harm the bacteria....

Selenium nanoparticles may act like antibacterial agents

Scientists have found that nanoparticles of selenium, an essential micronutrient, can be used as an antibacterial agent. Selenium is found naturally in wheat, eggs, cheese,...

New method to detect antibiotics-resistant bacteria

Scientists at the Kant Baltic State University have developed a method to quickly identify single antibiotic-resistant bacteria cells that are the agents of tuberculosis. This...
Transmission electron micrographs of reference serovar Typhi Ty2 strain. (a–d) Normal Salmonella cells and (e–h) cadmium adapted Salmonella cells. Arrows highlights the differences observed. Inset- White arrows marked the electron dense regions in the enhanced micrographic image.

How heavy metals are helping spread drug resistance

Exposure to cadmium is making typhoid-causing bacteria, Salmonella, stronger and difficult-to-treat with conventional antibiotics, a new study has suggested. Researchers have identified exposure to cadmium...
Hot chip: the nanomushroom chip used to grow bacterial colonies for testing

Chips, light and coding moves the front line in beating bacteria

Our immune system is consistently fighting against bacteria. Now, this consistent fight against bacteria has taken a new move with the announcement of a tool....
Retaliation: Toxin producers produce a small amount of toxin all the time (green and red cells). A provoking toxin-producer (right) is sensed through its released toxin by its competitor (left), which in turn becomes more aggressive by producing more toxin, causing significant damage to the provoker. The panels at the bottom show the difference in outcome when a strain is non-provoking (green colony, left panel) or provoking (green colony, right panel) against the same competitor (unlabelled colony in both panels).

Bacteria can ‘divide and conquer’ to vanquish their enemies

Bacteria frequently take part in 'warfare' by discharging toxins or different molecules that harm or slaughter contending strains. This war for assets happens in...

Bacterial balancing act: Preserving diversity while on the move

Varieties of bacteria guarantee the capacity to survive arbitrary changes in the earth. Yet, when a bacterial band starts to relocate, individual cell contrasts display...
