Plasmids and the spread of antibiotic resistance genes
Though the harnessing of antibiotics is one of the most significant human innovations, their efficacy is continuously eroded by the craftiness of their microbial targets. Once a single bacterium mutates to become resistant to antibiotics, it can tran.....»»
Scientists propose drug-free method to combat antibiotic-resistant bacteria
Recent estimates indicate that deadly antibiotic-resistant infections will rapidly escalate over the next quarter century. More than 1 million people died from drug-resistant infections each year from 1990 to 2021, a recent study reported, with new p.....»»
Discovery of 2,586 orphan genes in Rosa chinensis reveals stress adaptation and flower development
Orphan genes, found only in specific lineages, are key drivers of new functions and phenotypic traits. This discovery lays a foundation for understanding how roses thrive under environmental challenges......»»
Misinformation Really Does Spread like a Virus, Epidemiology Shows
“Going viral” appears to be more than just a catchphrase when it comes to the rampant spread of misinformation.....»»
The U.S. Must Lead the Global Fight against Superbugs
Antimicrobial resistance could claim 39 million lives by 2050, yet the pipeline for new antibiotics is drying up. U.S. policy makers can help fix it.....»»
Calling all Ars readers! Your feedback is needed.
We want to hear from you. Many of you know that most of our staff is spread out all over these United States, but what you might not know is that it has been more than five years.....»»
From pets to pests: Researchers explore new tool to fight disease-carrying insects
Arkansas researchers are testing a product commonly used to treat ticks and fleas on pets to target fly and mosquito larvae with the goal of helping reduce the spread of diseases carried by these insects......»»
Bioluminescent proteins made from scratch enable non-invasive, multi-functional biological imaging
Bioluminescence is the natural chemical process of light creation in some living creatures that makes fireflies flicker and some jellyfish glow. Scientists have long been interested in borrowing the secrets of these animals' light-producing genes to.....»»
Building a diverse wildland fire workforce to meet future challenges
Every year around this time, California's wildland firefighters hold their breath as hot, dry winds threaten to spread flames across the state. As such conflagrations grow in size and severity throughout the Western U.S., the strain on fire managers.....»»
Down in the weeds: How host specificity testing works
Fortunately for us, weeds have enemies. Biocontrol harnesses the power of these natural adversaries, limiting the otherwise unchecked growth and spread of weeds. Biocontrol methods offer safe, cost-effective, landscape-scale weed control......»»
New CRISPR system for gene silencing doesn"t rely on cutting DNA
Scientists from Vilnius University's (VU) Life Sciences Center (LSC) have discovered a unique way for cells to silence specific genes without cutting DNA. This research, led by Prof. Patrick Pausch and published in the journal Nature Communications,.....»»
New insights into the Denisovans—the hominin group that interbred with modern day humans
Scientists believe individuals of the most recently discovered hominin group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history......»»
A causal theory for studying the cause-and-effect relationships of genes paves the way for targeted treatments
By studying changes in gene expression, researchers learn how cells function at a molecular level, which could help them understand the development of certain diseases......»»
How honeybees can help us monitor pollution across Canada
Canada has more than 13,000 beekeepers with almost 1,000,000 beehives spread across every province. Together, they produce about 40,000,000 kilograms of honey each year. That is enough for roughly one kilogram of honey for every Canadian......»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Misinformation really does spread like a virus, according to mathematical models drawn from epidemiology
We're increasingly aware of how misinformation can influence elections. About 73% of Americans report seeing misleading election news, and about half struggle to discern what is true or false......»»
Latest space station science reveals news for astronaut health and telescope longevity
Recent findings from the International Space Station address wound healing, fine motor control in space, and radiation resistance by the station's Glowbug gamma-ray telescope......»»
Not the usual suspects: Research reveals novel genetic basis of pest resistance to biotech crops
If left unchecked, insect pests can devastate crops. To minimize damage and reduce the need for insecticide sprays, crops have been genetically engineered to produce bacterial proteins that kill key pests but are not harmful to people or wildlife. Ho.....»»
Nitric oxide treatment preserves fresh walnuts, reduces decay and maintains quality
New research reveals that sodium nitroprusside (SNP) treatment significantly reduces decay and maintains the appearance of walnuts, enhancing both disease resistance and overall quality. This breakthrough offered a practical solution for extending th.....»»
The Virus That Causes Mpox Keeps Getting Better at Spreading in People
Analysis of a strain of the virus circulating in Central Africa shows genetic mutations indicative of sustained human-to-human spread.....»»
