Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Pigment production adapted to cultural changes and availability of mineral resources 40,000 years ago in Ethiopia
An international research team from Spain and France has carried out the chemical and technological analysis of the largest known collection of red and yellow mineral pigments, commonly called ochre, dated to the Middle Stone Age, between 300,000 and.....»»
New method combines DNA nanoballs and electronics to enable simple pathogen detection
Researchers at Karolinska Institute have developed a novel method using DNA nanoballs to detect pathogens, aiming to simplify nucleic acid testing and revolutionize pathogen detection. The study's results, published in Science Advances, could pave th.....»»
Novel membrane could reduce energy expenditure in separating molecules for desalination, drug development
Separating molecules is critical to producing many essential products. For example, in petroleum refining, the hydrocarbons—chemical compounds composed of hydrogens and carbons—in crude oil are separated into gasoline, diesel and lubricants by so.....»»
X peppers ads without labels in some users’ Following feed
A new discovery has revealed that X (Twitter) is showing ads in the Following feed to users without labels – making them appear like regular content. While the rogue ads can be tough to discern, here’s a trick to check if you’ve got unmarked ad.....»»

RNA modifications are dynamic and reversible chemical modifications on substrate RNA that regulate mRNA stability, translation, and localization. This review is designed by Dr. Junhong Han and written by his postdoctoral researcher Dr. Lei Qiu and P.....»»
How these parasitic worms turn brown shrimp into bright orange “zombies”
Infection activates gene expression for pigmentation, suppresses immune response. Enlarge / Orange amphipods caught the eye (and interest) of Brown University graduate students conducting field research. (credit: David Johnson).....»»
Better sweat collection method could improve biomarker analysis
The chemical composition of human sweat tells us a lot about our health, but collecting it for analysis can be tricky. Current devices worn on the skin fill reservoirs one at a time but do not reflect how our rate of sweating changes throughout the d.....»»
The room-temperature superconductor that wasn’t
We have good explanations for why a chemical called LK-99 behaved the way it did. Enlarge / Levitation like this will apparently continue to require extremely cold temperatures for now. (credit: ClaudeLux) The summer of.....»»
A Flesh-Eating Bacterium Is Creeping North as Oceans Warm
The Vibrio vulnificus pathogen thrives in hot coastal waters, and beachgoers can contract it via a small cut or scrape. It can also kill them in two days......»»
From unsuspecting click to data compromise
Phishing is a pervasive and ever-evolving cyber threat that has become a primary concern for individuals, organizations, and cybersecurity experts worldwide. This deceptive practice involves cybercriminals using various tactics to trick individuals i.....»»
Scientists synthesize new organometallic "sandwich" compound capable of holding more electrons

Chemical engineers draft a roadmap for research into metallic "sponges" for clean hydrogen
Metal organic frameworks (MOFs) could deliver a major efficiency boost to the photocatalytic production of clean hydrogen. Chemical engineers have drafted a comprehensive overview of the state of their field and a plan for where it needs to focus......»»
Striking gold with molecular mystery solution for potential clean energy
Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed the.....»»
Study finds a large proportion of Michigan"s C. jejuni infections are caused by antibiotic resistant strains
Working with the Michigan Department of Health and Human Services, Michigan State University researchers have shown that antibiotic resistance genes are prevalent in the bacterium Campylobacter jejuni, a leading cause of foodborne illness......»»
Antibiotics found to promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill "good" bacteria in the gut. This is according to new research led by Imperial College London scientists, which could lead to better patient risk assessment and "microbio.....»»
Organic nanosensors may be able to detect harmful pesticides thanks to new research
Researchers at Concordia have developed a new system using tiny nanosensors called carbon dots to detect the presence of the widely used chemical glyphosate. Their research, titled "Ratiometric Sensing of Glyphosate in Water Using Dual Fluorescent Ca.....»»
Surpassing the human eye: Machine learning image analysis rapidly determines chemical mixture composition
Have you ever accidentally ruined a recipe in the kitchen by adding salt instead of sugar? Due to their similar appearance, it's an easy mistake to make. Similarly, checking with the naked eye is also used in chemistry labs to provide quick, initial.....»»
Semiconductor photocatalyst helps to realize borylation reaction
A research group led by Prof. Dai Wen from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has realized borylation reactions involving N-heterocyclic carbene boranes (NHC-BH3) with a simple and efficient heter.....»»
Turtles Carry Signs of Humanity’s Nuclear History in Their Shells
Turtles’ shells contain a chemical record of the environment—including highly enriched uranium, an indicator of nuclear weapons development. What can we learn from these accidental archivists?.....»»
Researchers produce polymers from ballbot-type carbenes for the first time
