This modified stainless steel could kill bacteria without antibiotics or chemicals
An electrochemical process developed at Georgia Tech could offer new protection against bacterial infections without contributing to growing antibiotic resistance......»»
Scientists explore role of intestinal bacteria in cancer prevention
Certain intestinal bacteria are found more frequently in countries such as Norway than in a number of other countries and there is also a higher incidence of bladder cancer, bowel cancer and prostate cancer. These findings may lead to new opportuniti.....»»
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.....»»
New pathway found for regulating zinc in E. coli
Cornell researchers have discovered a pathway by which E. coli regulates all-important zinc levels, an insight that could advance the understanding of metal regulation in bacteria generally and lead to antibacterial applications such as in medical in.....»»
Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
Protein biosynthesis—the process whereby cells produce protein molecules, which are essential for life and growth—is a highly complex and strictly regulated affair. An interdisciplinary team led by LMU biologist PD Dr. Jürgen Lassak has now disc.....»»
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.....»»
Peat-bog fungi produce substances that kill tuberculosis-causing bacteria
An analysis of fungi collected from peat bogs has identified several species that produce substances toxic to the bacterium that causes the human disease tuberculosis. The findings suggest that one promising direction for development of better treatm.....»»
Open-source platform supports large imaging data analysis of single cell responses to manipulation
Modern day drug discovery is shifting from single end point assays to more complex phenotypic assays that query single cell and population responses to chemicals and genetic manipulation......»»
"Forever chemicals" are polluting African waters
Every week seems to bring a new report about where "forever chemicals" have been found: in soil, drinking water, our bodies and marine animals. Their proper scientific name is perfluoroalkyl and polyfluoroalkyl substances (PFAS). But they're more com.....»»
Biochemists uncover a new enzyme subclass in antimicrobial lanthipeptide biosynthesis
Biochemists from the National University of Singapore (NUS) have discovered a new subclass of trifunctional enzymes in gram-positive bacteria, which play a critical role in the biosynthesis of an antimicrobial lanthipeptide......»»
Toxic site is leaking cancer-causing chemicals in Grand Prairie, Texas: When will it be cleaned?
The Environmental Protection Agency has finalized a plan to clean a toxic site leaking cancer-causing chemicals under dozens of homes in Grand Prairie, Texas......»»
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.....»»
Scientists reveal structural link for initiation of protein synthesis in bacteria
Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mys.....»»
COP29: Climate change could kill millions—and world leaders must work to limit fatalities
The COP29 climate change conference has come to a close—as per normal it looks like very little will be done......»»
Suicide Squad: Kill the Justice League price plummets to $4 in Steam Autumn Sale
Suicide Squad: Kill the Justice League just got a dramatic 95% price cut during the Steam Autumn Sale, cutting the price down to under $5......»»
Study discovers how algae produce a hormone they use to communicate
A study at the University of Cordoba shows how algae produce auxin, a plant hormone, opening a path of communication with bacteria to generate synergies that could benefit agricultural production. The paper is published in the journal iScience......»»
Cobalt ions, not covalent organic frameworks themselves, drive catalytic activity, study finds
Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjust.....»»
Targeting bacterial defense mechanisms for effective antibiotic treatment
In addition to the urgent need for new antibiotics, alternative strategies are required to tackle the problem of antibiotic resistance. Michaela Wenzel, Associate Professor at Chalmers University of Technology, is investigating bacterial defenses aga.....»»
New mechanism in bacterial DNA enzyme opens pathways for antibiotic development
Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Center have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic target. This enzyme, present in bacteria but absent i.....»»
New transformer-based AI model enhances precision in rice leaf disease detection
Rice is one of the world's most essential food crops, but its production is constantly threatened by leaf diseases caused by pathogens such as fungi, bacteria, and viruses. These diseases, which manifest as spots or blotches on leaves, can severely i.....»»
Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission......»»
