Gulls: Sentinels of bacteria in the environment
Gulls are one of the main wild birds that act as reservoirs of Campylobacter and Salmonella, two most relevant intestinal antibiotic-resistant bacteria causing gastroenteritis in humans. Therefore, according to an article published in the journal Sci.....»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
Phage cocktail shows promise against drug-resistant bacteria
Researchers have a new battle tactic to fight drug-resistant bacterial infections. Their strategy involves using collections of bacteriophages, viruses that naturally attack bacteria. In a new study, researchers at the University of Chicago Pritzker.....»»
To really be greener, businesses need to look to the boardroom
Greenwashing scandals—the practice of misleading the public about what action a company or organization is taking to protect the environment—are on the rise. As the climate crisis intensifies, greenwashing represents a significant obstacle to mee.....»»
New lunar distress system could safeguard future astronauts
A team of international scientists has taken a significant step towards making lunar exploration safer, proposing a distress monitoring and rescue system designed for the moon's unique and challenging environment......»»
Study sheds light on limitations of zooplankton for inactivating pathogen contaminated water
Scientists at The University of Texas at El Paso and Stanford University were recently surprised to find that the natural community of zooplankton—tiny, aquatic animals known to graze on bacteria—present in freshwater and saltwater do not clean w.....»»
More consumption, more demand for resources, more waste: Why urban mining"s time has come
Pollution and waste, climate change and biodiversity loss are creating a triple planetary crisis. In response, UN Environment Program executive director Inger Andersen has called for waste to be redefined as a valuable resource instead of a problem......»»
Wastewater bacteria can break down plastic for food, yielding new possibilities for cleaning up plastic waste
Researchers have long observed that a common family of environmental bacteria, Comamonadacae, grow on plastics littered throughout urban rivers and wastewater systems. But exactly what these Comamonas bacteria are doing has remained a mystery......»»
These New Biomaterials Can Help Decarbonize Fashion and Construction
Designers are imagining a future where bacteria powers both clothing and cement—and their ideas are coming to a shop near you......»»
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.....»»
Plant pathologists spearhead Fusarium head blight research on hemp
Extension faculty at the University of Kentucky (UK) Martin-Gatton College of Agriculture, Food and Environment are advancing the fight against Fusarium head blight (FHB) in hemp. This disease, caused by multiple species of the Fusarium fungus, threa.....»»
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......»»
Northeastern Europe has only been "stork country" for a few centuries, study reveals
In legends and fables, it brings luck, children and prosperity. Today, its appearance is seen as a sign of a healthy environment. Hardly any other bird in Europe has such positive connotations as the white stork Ciconia ciconia. But how old is this c.....»»
Increased sea surface cooling from hurricanes observed along the Southeast Coast of the United States in recent decades
Utilizing satellite observations and ocean reanalysis datasets, researchers have analyzed the change in sea surface cooling induced by hurricanes and the corresponding ocean-atmosphere environment along the Gulf and Southeast coastal regions of the U.....»»
Cities unprepared for impact of climate change, says report
Half of the world's population lives in cities, and that proportion is expected to increase to 70% by 2050. With their large populations, lack of green spaces that can cool a warming environment, and aging infrastructure that is vulnerable to floods.....»»
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.....»»
The boomer generation hit the economic jackpot. Young people will inherit their massive debts
Young people in Britain could be forgiven for despairing at the financial pressures they face—and feeling that previous generations enjoyed a much fairer economic environment. Then just to add to their worries about home ownership and a precarious.....»»
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.....»»
Ars in San Jose recap: Infrastructure, sustainability, AI, cocktails
We came, we saw, we talked, we schmoozed, we toured the Computer History Museum! Enlarge / Dr. John Timmer, Jeff Ball, Joanna Wong, and Lee Hutchinson discussing infrastructure and the environment. (credit: Kimberly White/Getty I.....»»
