Urban Birds Are Harboring Antibiotic-Resistant Bacteria
Exposure to bacteria in landfill sites and polluted rivers may explain prevalence among city-dwelling birds......»»
Photosynthesis powers our world, but what fuels this fundamental process?
It's hard to overstate the importance of photosynthesis, the biochemical pathway by which plants, algae, and certain bacteria convert the sun's energy into the organic material that feeds the entire living biosphere. But there are still aspects of th.....»»
Unexpected phage protein function discovered in bacteria battle
An unexpected find has enabled important progress to be made in the battle against harmful bacteria. An international team of researchers, led by Professor Peter Fineran from the University of Otago, investigated a particular protein used by bacteria.....»»
The geometry of life: Physicists determine what controls biofilm growth
From plaque sticking to teeth to scum on a pond, biofilms can be found nearly everywhere. These colonies of bacteria grow on implanted medical devices, our skin, contact lenses, and in our guts and lungs. They can be found in sewers and drainage syst.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Certain bacteria or fungi could combat a plant pathogen that attacks common vetch
Anthracnose, a severe disease caused by the Colletotrichum spinaciae plant pathogen, often occurs in common vetch, a widely grown legume. Chemicals are not recommended for disease management because the plants are used as livestock feed. A new study.....»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
Low-cost depth imaging sensors achieve 97% accuracy in rapid plant disease detection
A research team has investigated low-cost depth imaging sensors with the objective of automating plant pathology tests. The team achieved 97% accuracy in distinguishing between resistant and susceptible plants based on cotyledon loss. This method ope.....»»
New microbe-central model predicts global grassland soil pH under climate change
In a study published in One Earth on July 5, a research team led by Prof. Deng Ye from the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences proposed the core-bacteria-forecast model (CoBacFM), which links the changes.....»»
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.....»»
AI able to identify drug-resistant typhoid-like infection from microscopy images in matter of hours
Artificial intelligence (AI) could be used to identify drug resistant infections, significantly reducing the time it takes for a correct diagnosis, Cambridge researchers have shown. The team determined that an algorithm could be trained to identify d.....»»
Starlings" migratory behavior found to be inherited, not learned
Young, naïve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other......»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors" reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought......»»
Study reveals rapid evolution and global spread of Pseudomonas aeruginosa
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven b.....»»

New theory reveals fracture mechanism in soft materials
A new theory has finally deciphered the physical mechanisms of fracture in soft materials. This discovery could soon lead to new, defect-free materials that are more resistant and durable as well as environmentally friendly. The article "Elastic inst.....»»
High-altitude cave used by Tibetan Buddhists yields a Denisovan fossil
Cave deposits yield bones of sheep, yaks, carnivores, and birds that were butchered. Enlarge / The Baishiya Karst Cave, where the recently analyzed samples were obtained. (credit: Dongju Zhang’s group (Lanzhou University)).....»»
Unveiling East Asia"s urban landscape: A massive mapping project illuminates 280 million buildings
Accurate and comprehensive building data is critical for urban management and planning. Existing datasets, such as those from Microsoft and OpenStreetMap, often lack completeness and accuracy in East Asia, limiting their utility for large-scale appli.....»»
Some birds win and some lose with sea level rise, expert says
Global sea level rise is accelerating every year due to climate change, and it could threaten the very existence of some coastal bird species......»»
