Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»

Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»

Yeast chit-chat: How microorganisms communicate food shortages
To grow and survive, tiny organisms such as yeast must sometimes adapt their nutrient sources in response to changes in the environment. FMI researchers have now found that yeast cells communicate with each other to use less favorable nutrients if th.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
Researchers discover tumors inherited by generations of jellyfish-like creatures
Researchers from the CANECEV laboratory, an international collaboration between Deakin University and the University of Montpellier, have observed for the first time the birth of transmissible tumors in freshwater brown hydras—tiny, jellyfish-like.....»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice
It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics.".....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
