Harmful bacteria can elude predators when in mixed colonies
Efforts to fight disease-causing bacteria by harnessing their natural predators could be undermined when multiple species occupy the same space, according to a study by Dartmouth College researchers......»»
Bacteria-derived enzyme shows potential for polyethylene biodegradation
Every year, 400 million tons of plastic products are produced worldwide, half of which are single-use items discarded within a year. In particular, non-biodegradable plastic waste, which takes over 500 years to decompose naturally, is mostly treated.....»»
Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Scientists inject bacteria into fungi to study endosymbiosis
Endosymbiosis is a fascinating biological phenomenon in which an organism lives inside another. Such an unusual relationship is often beneficial for both parties. Even in our bodies, we find remnants of such cohabitation: mitochondria evolved from an.....»»
LEGO-inspired RNA sensors enable customizable gene control
A research team has developed an RNA-based sensor platform that can regulate gene expression in bacteria. Their findings were recently featured in the journal Advanced Science......»»
eBay listings for banned chemicals shielded by Section 230, judge rules
DOJ can’t force eBay to remove environmentally harmful product listings. eBay has defeated a lawsuit that the US Department of Justice raised last fall, which alleged that eBay.....»»
Microsoft discontinues HoloLens 2 with no plans to introduce a replacement
While companies like Apple and Meta have been investing in their own mixed reality headsets, Microsoft seems to be going in the opposite direction. The company announced on Tuesday that it’s discontinuing HoloLens 2, its advanced XR headset. mo.....»»

Farm waste can filter microplastics in surface runoff, prevent pollution
Using treated plant waste as a filter reduced the presence of harmful microplastics in agricultural runoff by more than 92%, according to a new study authored by a University of Mississippi research team......»»
Hunting down giant viruses that attack tiny algae
They were said to come from outer space, and there were even claims that they were actually bacteria and that they undermined the very definition of viruses. Giant viruses, nicknamed "giruses," contain enormous quantities of genetic material—up to.....»»
Bioengineers and chemists design fluorescent 3D-printed structures with potential medical applications
In a process as simple as stirring eggs and flour into pancakes, University of Oregon researchers have mixed fluorescent ring-shaped molecules into a novel 3D printing process. The result: intricate glowing structures that support the development of.....»»
Forest loss forces langur species to interbreed, study shows
Research shows a threatening development for two endangered primate species in Bangladesh: Phayre's langurs (Trachypithecus phayrei) and capped langurs (Trachypithecus pileatus). In mixed groups of these two species, hybrids have been found and genet.....»»
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.....»»
Humbug damselfish use "motion dazzle" to evade predators
When thinking of animal camouflage, we typically imagine creatures remaining still, blending seamlessly into their surroundings. But remaining motionless isn't always practical, and many animals are highly mobile, constantly moving through their envi.....»»
Study shows virtual reality may help pedestrians and cyclists avoid harmful pollutants
Physics-informed virtual reality could be key to reducing the exposure of pedestrians and cyclists to harmful, non-exhaust vehicle emissions, according to a study published 25 Sep in the Royal Society Open Science journal......»»
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......»»
