Antibiotic resistance from random DNA sequences
An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The.....»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
Franklin expedition captain who died in 1848 was cannibalized by survivors
Scientists matched DNA of living descendent to Capt. James Fitzjames of the HMS Erebus. Scientists at the University of Waterloo have identified one of the doomed crew members of.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Tailwinds don’t help “everesting” cyclists
"There are no clever tricks to get around the necessary diet and exercise." Enlarge / Physicist Martin Bier in an aerodynamic tuck, a cycling position that reduces wind resistance. (credit: Martin Bier) Many avid bicycli.....»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
VW CEO Oliver Blume expects significant concessions from unions in crunch talks
VW Group CEO Oliver Blume said the automaker's costs in Germany are too high compared to international competition, setting up a clash with unions who have pledged fierce resistance to job cuts and plant closures......»»
Potential breakthrough in battle against antibiotic resistance from historic brine
A historic brine bath is the site of a potential breakthrough in the prevention of antibiotic resistance in relation to MRSA, and other hospital pathogens......»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
Genome sequence analysis identifies new driver of antimicrobial resistance
Antibiotics are a lifesaving tool. Yet, due to their chronic overuse, microbes are evolving and developing immunity against them. As a result, once-effective medications can no longer stave off infections, complicating treatment and increasing mortal.....»»
Researchers explore physiological and molecular processes underlying graft healing
Grafting has long been a cornerstone in agriculture and forestry, allowing for the propagation of desirable plant traits and improved resistance to environmental challenges. Despite its widespread application, grafting still encounters obstacles, inc.....»»
Silencing in action: How cells "repress" genomic remnants of ancient viruses
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of "cryptic" genomic regions, including ancient viral sequences......»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»

Soil nutrient levels associated with suppression of banana Fusarium wilt disease
Fusarium wilt poses a significant threat to global agriculture, particularly affecting the banana industry, where it is commonly known as banana Panama disease. As a result, enhancing soil-related resistance has emerged as a crucial, environmentally.....»»
DNA demethylation boosts tomato resistance to gray mold, study finds
Postharvest decay in fruits, primarily caused by pathogenic fungi, remains a major obstacle to agricultural sustainability and food security. Despite advances in fungicides and storage technologies, losses remain substantial, especially in developing.....»»
Researchers uncover new infection-fighting molecules through "molecular de-extinction"
A new study led by Cesar de la Fuente, Ph.D., Presidential Assistant Professor of Psychiatry, Microbiology, Chemistry, Chemical and Biomolecular Engineering, and Bioengineering at the University of Pennsylvania, has uncovered sequences for infection-.....»»
Researchers identify new tools for anti-Acinetobacter drug development and AMR preparedness
University of Liverpool researchers have engineered a library of strains that can be used to develop new antibacterial compounds to help address antimicrobial resistance (AMR) in Acinetobacter baumannii bacteria......»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
