New molecule found to suppress bacterial antibiotic resistance evolution
Researchers from the University of Oxford have developed a new small molecule that can suppress the evolution of antibiotic resistance in bacteria and make resistant bacteria more susceptible to antibiotics. The paper, "Development of an inhibitor of.....»»
Ferns" ability to evolve "backward" offers insights into the meandering path of evolution
Imagine a photograph of your great-grandparents, grandparents and parents side by side. You'd see a resemblance, but each generation would look distinct from its predecessors. This is the process of evolution in its simplest form: descent with modifi.....»»
Study maps bed bugs" genomes in unprecedented detail to find out why they just won"t die
Scientists mapped near-gap-free and near-error-free genomes of a susceptible bed bug strain and a superstrain around 20,000 times more insecticide-resistant, offering the broadest look yet at the full scope of their resistance mutations......»»
UK"s inland bathing sites tainted by chemical pollutants and antibiotic resistant genes, researchers find
The U.K.'s rivers are contaminated with a mixture of chemical pollutants and antibiotic resistant genes, which could be causing severe harm to people and aquatic species, according to the findings of a new study......»»
Across southeastern US, weedy rice steals herbicide resistance from crop rice
Weedy rice is a close relative of cultivated rice that infests rice fields worldwide and drastically reduces yields. To combat this agricultural pest, rice growers in the southeastern United States have been planting rice cultivars that were tweaked.....»»
Rapid evolution: African clawed frog sex determination challenges prevailing theory
Researchers at McMaster University have uncovered unexpected diversity in the genetic processes that determine the sex of the African clawed frog, a significant discovery in what was already one of the most widely studied amphibians in the world......»»
Protein"s "hopping" behavior uncovers new drug development avenues
Since 2006, Ruben Gonzalez's Columbia lab has used single-molecule light microscopy to study the structural dynamics of biomolecules......»»
Genetic method leverages bacterial transfer mechanism to produce new active ingredients
Microorganisms produce a wide variety of natural products that can be used as active ingredients to treat diseases such as infections or cancer. The blueprints for these molecules can be found in the microbes' genes, but often remain inactive under l.....»»
Study reveals complex bacterial dynamics of urinary tract infections
Urinary tract infections (UTIs) are a major widespread health issue that affects millions of patients globally every year. These infections are not only uncomfortable, but also challenging to treat, as they may often reoccur after the first infection.....»»
How soil bacteria contribute to the growing global issue of antibiotic resistance
Soil plays a much bigger role in the spread of antibiotic resistance than one might imagine. Surprisingly, the ground beneath us is packed with antibiotic resistance genes (ARGs)—tiny codes that allow bacteria to resist antibiotics. Human activitie.....»»
New insights into the evolution and paleoecology of mosasaurs
Mosasaurs are extinct marine lizards, spectacular examples of which were first discovered in 1766 near Maastricht in the Netherlands, fueling the rise of the field of vertebrate paleontology. Paleontologist Michael Polcyn presented the most comprehen.....»»
A new species of flying reptile reshuffles the timeline of pterosaur evolution
About 230 million years ago, almost 80 million years before the first bird appeared, their distantly related cousins, the pterosaurs took to the sky, as the first group of active fliers among the vertebrates. Pterosaurs developed active, flapping fli.....»»

Morphology study highlights diverse jaw evolution in lizards and snakes
A University of Bristol study has shed light on how lizards and snakes—the most diverse group of land vertebrates with nearly 12,000 species—have evolved remarkably varied jaw shapes, driving their extraordinary ecological success......»»
Scientists collect "microbial fingerprints" found in household plumbing
The plumbing systems in households can teem with generally harmless microbial life, but scientists have not had an opportunity to fully document the bacterial communities within people's homes......»»
Some glaciers in Antarctica have maintained considerable stability over the last millennia
A research study led by Marc Oliva, researcher at the University of Barcelona, analyzes the evolution of glaciers on the Hurd Peninsula in Antarctica, home to the Spanish Juan Carlos I Antarctic Base. This study, published in the journal Quaternary S.....»»
Extensive antimicrobial usage sparks warning over increased resistance in locations across Australia
University of Queensland research has found antimicrobial usage is significantly higher in affluent communities in Australia. Samples have been collected from 50 wastewater treatment plants in locations across Australia servicing about 11.3 million p.....»»
Developing a cyclic molecule that captures phosphate in harmony with water molecules
Researchers at University of Tsukuba, Osaka University, and Kitasato University developed a novel amide cyclodextrin (cyclic oligosaccharide) that can selectively capture phosphate ions in water. In addition, the researchers revealed the mechanism by.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Discovery of key protein complex shows evolution and adaptability of photosynthetic organisms
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein complex used by plants and cyanobacteria to convert sunlight into chemical energy. This discovery sheds light on the evolution a.....»»
Chemists develop color-changing test for rapid salmonella detection
A group of chemists at the University at Albany have developed a new method for fast-acting salmonella detection. The test employs a paper strip that changes color in the presence of the bacterial genome, enabling quick screening for salmonella in fo.....»»
