Disrupted movement makes macrophages more lethal to tuberculosis bacteria
Macrophages—the front line of our immune system—protect us from infections. But in the case of the tuberculosis bacteria, this often goes wrong. The group of Annemarie Meijer from the Leiden Institute of Biology has now discovered that macrophage.....»»

Positive associations revealed as key driver in maintaining soil biodiversity and ecological networks
In a study published in PNAS, researchers analyzed 151 ecosystems across six continents, delved into the intricate coexistence network among diverse species including bacteria, fungi, protists, and invertebrates, and for the first time, linked biotic.....»»
Study finds commensal gut bacteria develop resistance in response to antibacterial treatment
An international team of microbiologists and immunologists has found that commensal gut bacteria develop resistance to antibacterial therapies for infections. In their study, reported in the journal Science Translational Medicine, the group monitored.....»»
New study validates method for guided discovery of 3D flat-band materials
Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place......»»
Understanding nutrient cycling between algae and bacteria could lead to increased biofuel production
The interactions between algae and bacteria are essential to the primary productivity of Earth's oceans and surface waters. Bacteria can increase the productivity of algae by producing key factors, such as vitamins, iron-chelating molecules, and grow.....»»
Inner ear of 6-million-year-old ape fossil reveals clues about the evolution of human movement
Humans and our closest relatives, living apes, display a remarkable diversity of types of locomotion—from walking upright on two legs to climbing in trees and walking using all four limbs......»»
