Bacteria Cells Respond Differently to Lack of Nutrients

No two bacteria are identical – even when they are genetically the same. New research reveals the conditions under which bacteria become individualists and how they help their group grow when times get tough. Whether you are a human or a bacterium, your environment determines how you can develop. In particular, there are two fundamental […]

Study Shows Bacteria Can Be Spatially Excluded from the Exchange of Amino Acids

New research shows that bacteria, which reciprocally exchange amino acids, stabilize their partnership on two-dimensional surfaces and limit the access of non-cooperating bacteria to the exchanged nutrients. In natural microbial communities, different bacterial species often exchange nutrients by releasing amino acids and vitamins into their growth environment, thus feeding other bacterial cells. Even though the […]

Engineered Probiotics Can Detect Tumors in the Liver

By using probiotics, a team of engineers has devised a new way to detect cancer that has spread to the liver. Many types of cancer, including colon and pancreatic, tend to metastasize to the liver. The earlier doctors can find these tumors, the more likely that they can successfully treat them. “There are interventions, like […]

Scientists Reverse Bacterial Resistance to Antibiotics

A newly published study details how a team of researchers returned drug-resistant bacteria to a pre-resistant state. Biologist Miriam Barlow of the University of California, Merced, and mathematician Kristina Crona of American University tested and found a way to return bacteria to a pre-resistant state. In research published in the open-access journal PLOS ONE, they […]

Bacteria Connect to Each Other Via Nanotubes

New research from the Max Planck Institute shows that some bacteria can form nanotubular structures between single cells that enable a direct exchange of nutrients. It is well-known that bacteria can support each others’ growth and exchange nutrients. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, and their colleagues at the […]

New Nanotech Pores Keep Bacteria from Sticking to Surfaces

A team of researchers used anodization to create nanoscale pores that change the electrical charge and surface energy of a metal surface, creating a nanoporous surface called alumina that prevents bacteria from attaching to the surface. Just as the invention of nonstick pans was a boon for chefs, a new type of nanoscale surface that […]
