Could one bacterium put damselflies in distress?
Many insect species are currently expanding their geographical ranges in response to climate change. In the northern hemisphere, most of these species are moving northward, to escape the warming climate in the south......»»
People in financial distress behave more morally, says study
A new study conducted at Reichman University, in collaboration with Aarhus University in Denmark, challenges the negative stereotypes associated with individuals facing economic hardship. The study, led by Prof. Guy Hochman of Reichman University's B.....»»
Tuberculosis under the sea: A marine sponge microbe provides insights into the bacterium"s evolution
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment st.....»»
Safeguarding produce from E. coli contamination
Leafy greens such as spinach and lettuce are among the most nutrient-packed foods we can eat—and some of the most prone to make us miserable, or worse. The pathogenic bacterium Escherichia coli O157:H7 causes millions of illnesses globally each yea.....»»
Modular design: New insights into protein factories in human mitochondria
The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochondria.....»»
Respiratory bacteria "turn off" immune system to survive, study finds
Researchers from The University of Queensland have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The research was published in PLOS Pathogens......»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»

Researchers develop tool for detecting foodborne pathogen that causes severe symptoms in children
The prevalence of pathogenic E. coli has meant the frequent misidentification of a similar bacterium of the Escherichia genus. E. albertii is an emerging zoonotic foodborne pathogen, first isolated in Bangladesh in 1991. Large-scale outbreaks of food.....»»
New discoveries about the nature of light could improve methods for heating fusion plasma
Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plas.....»»
Body lice may be bigger plague spreaders than previously thought
A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics......»»
Fast track to food safety: New test spots seafood pathogen in 30 minutes
Vibrio parahaemolyticus is a Gram-negative, halophilic bacterium prevalent in marine environments and is the primary cause of acute hepatopancreatic necrosis, also known as early death syndrome, in aquaculture......»»
Researchers target spermidine production to combat emerging drug resistance in Salmonella
Food-borne diseases like typhoid, caused by Salmonella Typhimurium, are a severe threat to public health, especially in India. The indiscriminate use of antibiotics has allowed this bacterium to become resistant, posing a major hurdle in treating inf.....»»
Microbiome studies help explore treatments for genetic disorders
A collaboration has led to the identification, in a bacterium of the intestine, of new CRISPR-Cas9 molecules that could have a clinical potential to treat genetic diseases such as retinitis pigmentosa, through sub-retinal injections. Anna Cereseto an.....»»
Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
New study reveals novel approach for combating "resting" bacteria
Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade an.....»»
Global collaboration discovers drug target to combat chronic lung infection
Scientists have discovered a target for the development of a drug to combat a bacterium that can cause chronic lung infection in hospitalized patients, immunocompromised individuals and people with cystic fibrosis......»»
Making mural art helps teens cope
In Quebec's 2016–17 health survey of high-school students, 33% in grades 9, 10 and 11 reported experiencing high levels of psychological distress. And in 2021, a significant 6.1% said they had been diagnosed with an anxiety-depressive disorder, a 3.....»»
Amphibians use scream inaudible to humans for self-defense against predators, study suggests
A study reported in the journal acta ethologica has recorded the use of ultrasound by amphibians for the first time in South America. It also describes the first documented case of the use of ultrasound for defense against predators, in a distress ca.....»»
Researchers explain how green algae and bacteria together contribute to climate protection
A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the to.....»»
Veterinary surgeon: Spare flat-faced pets the respiratory distress
The demand for bulldogs and other flat-faced pets is at an all-time high. According to the American Kennel Club, from 2006-2016, the number of registered bulldogs and French bulldogs in the U.S. increased by 60% and 476%, respectively. In 2023, the F.....»»
