Some bacteria are suffocating sea stars, turning the animals to goo

Dermasterias imbricata

The mysterious culprit behind a deadly sea star disease is not an infection, as scientists once thought. Instead, multiple types of bacteria living within millimeters of sea stars’ skin deplete oxygen from the water and effectively suffocate the animals, researchers report January 6 in Frontiers in Microbiology. Such microbes thrive when there are high levels […]

How dangerous bacteria form colonies

The bacterial species Neisseria gonorrhoeae, pathogen of the sexually transmitted disease gonorrhoea, forms large colonies within a few hours, which consist of several thousand cells.

Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological […]

Bacteria can tell the time — ScienceDaily

Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological question and could have implications for the timing of drug delivery, biotechnology, and how we develop timely solutions for crop protection. […]

Nanocrystals that eradicate bacteria biofilm

To this, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials. A […]

Nanocrystals that eradicate bacteria biofilm — ScienceDaily

The COVID-19 pandemic is raising fears of new pathogens such as new viruses or drug-resistant bacteria. To this, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials. A joint research team from POSTECH and UNIST has introduced mixed-FeCo-oxide-based surface-textured nanostructures (MTex) […]

How ‘Iron Man’ bacteria could help protect the environment

This Geobacter cell—which looks a bit like a gray peanut in this microscope image—is speckled with a dark coating of cobalt minerals that would be toxic to many organisms.

How ‘Iron Man’ bacteria could help protect the environment — ScienceDaily

When Michigan State University’s Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not “environmentally relevant.” As other reviewers and the program manager didn’t share this sentiment, NSF funded the proposal. And, now, Reguera’s team has shown that microbes are capable of an […]
