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.....»»
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.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Q&A: Researcher discusses protecting the health of wildlife ecosystems
The plague is one of the deadliest bacterial infections in human history. An estimated 50 million Europeans died from it in the mid-1300s when it was known as the "Black Death.".....»»
Teaching evolution with conflict reduction practices increases acceptance, study finds
Students in biology classes accepted the theory of evolution more often when it was taught with conflict-reducing practices, including an emphasis on religious compatibility and autonomy, according to a study published December 4, 2024 in the open-ac.....»»
Scientists streamline creation of nucleoside analogs, a group of life-saving molecules
A team of researchers has found a quicker and more efficient way to create nucleoside analogs, a type of small molecule that can be used in treatments for everything from cancer to viral diseases......»»
Tiny dancers: Scientists synchronize bacterial motion
Researchers at TU Delft have discovered that E. coli bacteria can synchronize their movements, creating order in seemingly random biological systems. By trapping individual bacteria in micro-engineered circular cavities and coupling these cavities th.....»»
Enzyme study sheds light on the molecular mechanism behind "sleepiness"
Recent research has observed that chemical modifications called phosphorylation of proteins in brain neurons dynamically regulate sleep and wakefulness. But the protein kinases that suppress sleep and the dephosphorylation enzymes that control sleep.....»»
Physicists take a step closer to controlling single-molecule chemical reactions
Controlling matter at the atomic level has taken a major step forward, thanks to nanotechnology research by an international team of scientists led by physicists at the University of Bath......»»
Deep-sea marvels: How anglerfish defy evolutionary expectations
A Rice University study sheds light on the extraordinary evolution of anglerfish, a group of deep-sea dwellers whose bizarre adaptations have captivated scientists and the public alike. The research, published in Nature Ecology & Evolution, uncovers.....»»
Evidence of human-to-animal SARS-CoV-2 transmission in a Brazilian zoo
Universidade Federal de Minas Gerais-led research at the Belo Horizonte Zoo in Minas Gerais, Brazil, has detected SARS-CoV-2 in multiple captive wild mammals, revealing potential human-to-animal transmission and viral evolution in new hosts......»»
Resurrecting an ancestral protein as a novel tool to study RNA biology
By deducing the possible ancient forms of a bacterial enzyme, OIST scientists have resurrected one of its ancestral versions, with a comparably higher ability to chemically modify RNA......»»
What came first, life or evolution? Self-replicating molecules demonstrate basic principles of Darwinian evolution
We know that Darwinian evolution acts on all forms of life, but does evolution act on non-living materials as well?.....»»
New research reveals insights into gender equality in hunter-gatherer societies
A study published in the journal Evolution and Human Behaviour has uncovered fascinating insights into gender roles and cooperation in hunter-gatherer societies. The study, entitled "Bargaining between the sexes: outside options and leisure time in h.....»»
3D fossil scans investigate the origins of bipedal locomotion in human evolution
One of the most fascinating periods in the evolution of the human lineage is the appearance of the first ancestors capable of bipedalism. Knowing the type of locomotion used by many fossil species—walking upright on the ground or climbing from bran.....»»
The Whole Story of How Humans Evolved From Great Apes
The picture of human evolution has changed repeatedly and dramatically over the past half century, shaped by waves of new fossil discovery, technology, and scientific techniques......»»
Modified ribosomes could be a possible mechanism of antibiotic resistance
Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published in Nature Communications. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of.....»»
