Bacteria spin rainbow-colored, sustainable textiles
In the future, clothes might come from vats of living microbes. Reporting in the journal Trends in Biotechnology, researchers demonstrate that bacteria can both create fabric and dye it in every color of the rainbow—all in one pot. The approach offers a sustainable alternative to the chemical-heavy practices used in today's textile industry.

OTD in 1977 Carl Woese and George Fox redrew the tree of life.
They proposed a third “urkingdom”
—the “archaebacteria”
—in addition to eukaryotes and bacteria.
Woese later called this taxon “Archea.”
AFAIK, he didn’t publish his famous tree diagram until the late 80s.

Why was I today years old when I learned about bio-photovoltaics?
This is a technology which instead of using silicon wafers as the basis for photovoltaic cells, uses a sandwich comprising
1. A transparent window, to allow sunlight in;
2. Algae, to photosynthesise sugars;
3. A membrane to keep the algae separate from the bacteria;
4. Bacteria, which consume sugar and generate electricity;
5. A filter, to allow the biological components to breathe.

Nanostructured coatings physically puncture bacteria to prevent biofilm formation
Bacteria that multiply on surfaces are a major headache in health care when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth—one that does not rely on antibiotics or toxic metals.

Bats are one of the few animals that I genuinely don't enjoy being around.... but I still want them to thrive!

Weekend #Plankton Factoid 🦠🦐
Tintinnids ("tinkling bells") are ciliates found in fresh and saltwater known for their characteristic vase-shaped shell called a lorica. These are formed of tough proteins, incorporating minerals from the water and vary considerably by species. The shell offers protection and optimizes feeding on phytoplankton, bacteria and flagellates. These small pro…

Recipes are full of directions like “when the top starts to brown” or “when it is firm to the touch but not hard.”
Very often, the thing the directions are taking about is not the actual important trait, but a •proxy• for something important you can’t see directly. Maybe the inside of the bread is fully baked when the top starts to brown. Maybe dangerous bacteria are killed when the quiche is firm to the touch. (I am making this up; don’t @ me about quiche.)
Proxy indicators, heuristics, rules of thumb, call them what you like: they’re essential in cooking.

Nitrogen-doped carbon quantum dots enhance bacteria growth and biosensing signals

Nitrogen-doped carbon quantum dots enhance bacteria growth and biosensing signals
Carbon quantum dots (CQDs) are known for their antibacterial properties and ability to inhibit bacteria growth. In the current study, we observed a dopant and concentration-dependency on the antibacterial effect of CQDs. High concentrations of CQDs completely inhibited bacteria growth yet low concentrations enhanced growth. Unlike undoped CQDs, nitrogen-doped CQDs (N-CQDs) enhanced bacteria growth in a concentration-dependant manner and nitrogen/iron co-doped CQDs (Fe/N-CQDs) resulted in growth…

Disrupting bacterial 'chatter' could tip the balance for better oral health
Like all living things, bacteria adapt to survive. Over time, bacteria have been developing resistance to common antibiotics and disinfectants, which poses a growing problem for health care and sanitation. However, many species of bacteria are beneficial and even essential for human health. What if there was a way to change the behavior of bacteria in the body to prevent illness and poor health outcomes?

Confinement reduces surface accumulation of swimming bacteria
Many swimming bacteria naturally inhabit confined environments, yet how confinement influences their swimming behaviors remains unclear. Here, we combine experiments, continuum modeling and particle-based simulations to investigate near-surface bacterial swimming in dilute suspensions under varying confinement. Confinement reduces near-surface accumulation and facilitates bacterial escape. These effects are quantitatively captured by models incorporating the force quadrupole, a higher-order hyd…

Optimization of sequential therapies to maximize extinction of resistant bacteria through collateral sensitivity
Antimicrobial resistance (AMR) threatens global health. A promising and underexplored strategy to tackle this problem are sequential therapies exploiting collateral sensitivity (CS), whereby resistance to one drug increases sensitivity to another. Here, we develop a four-genotype stochastic birth-death model with two bacteriostatic antibiotics to identify switching periods that maximize bacterial extinction under subinhibitory concentrations. We show that extinction probability depends nonlinea…

Global initiative launches to prioritize conservation of vital microbial life
Microbes include bacteria, viruses, fungi, algae and archaea (single-celled microorganisms with a bacteria-like structure). They are invisible to the human eye, but they play a huge role, shaping ecosystems, producing food and regulating disease.

Geometry of Growing-Dividing Autocatalytic Dynamical Systems
We formalize the structure of a class of mathematical models of growing-dividing autocatalytic systems demonstrating that self-reproduction emerges only if the system's 'growth dynamics' and 'division strategy' are mutually compatible. Using various models in this class (the linear Hinshelwood cycle and nonlinear coarse-grained models of protocells and bacteria), we show that depending on the chosen division mechanism, the same chemical system can exhibit either (i) balanced exponential growth,…
