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.....»»
Apple Watch Series 10 to feature upgraded ECG and water resistance, new ‘Reflections’ face, more
As Apple’s next event draws closer, we learn more about the products the company will announce on Monday. Following a report earlier today about Apple Watch Series 10 featuring sleep apnea detection, 9to5Mac has now learned more details about the n.....»»
Physicists capture images of atoms flowing along a boundary without resistance despite obstacles in their path
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls......»»
Phage editing technology could lead to alternative treatments for antibiotic-resistant bacteria
As antibiotic resistance becomes an increasingly serious threat to our health, the scientific and medical communities are searching for new medicines to fight infections. Researchers at Gladstone Institutes have just moved closer to that goal with a.....»»
Combining aesthetics with fire-resistance for improved wood protection
Wood is a popular material for construction and furniture making due to its availability, easy processing, and strong mechanical properties. However, its flammability poses significant risks, particularly in historical buildings......»»
Breaking boundaries: PAM-less genome editing in soybean
CRISPR-Cas9 has transformed crop genetic improvement, yet its reliance on specific protospacer adjacent motif (PAM), sequences limits editing scope and efficiency. In soybean, a critical source of protein and oil, these limitations hinder the develop.....»»
Promising antibiotic candidates discovered in microbes deep in the Arctic Sea
Antibiotics are the linchpin of modern medicine: without them, anyone with open wounds or needing to undergo surgery would be at constant risk of dangerous infections. Yet we continue to face a global antibiotics crisis, as more and more resistant st.....»»
Bacteria able to overcome cost of vancomycin resistance in lab setting
Staphylococcus aureus has the potential to develop durable vancomycin resistance, according to a study published August 28, 2024, in the open-access journal PLOS Pathogens by Samuel Blechman and Erik Wright from the University of Pittsburgh, U.S.......»»
Proof-of-concept study demonstrates mid-infrared computational temporal ghost imaging
Ghost imaging in the time domain allows for reconstructing fast temporal objects using a slow photodetector. The technique involves correlating random or pre-programmed probing temporal intensity patterns with the integrated signal measured after mod.....»»
Ecosystems study finds the higher the environmental stress, the lower the resistance to global change
An international study led by the Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC), of the Spanish National Research Council (CISC), has shown that as the number of global change factors increases, terrestrial ecosystems become.....»»
A new pandemic could ride in on animals we eat, study warns
Researchers warn the animals we eat could be the gateway to a pandemic in the form of antimicrobial resistance, unleashing a wave of deadly superbugs......»»
Study finds "DNA scavengers" can stop some antibiotic resistance from spreading
For nearly a century, scientists have waged war on antibiotic-resistant microbes. Michigan State University researchers say they've found a new way to prevent it—by unleashing "DNA scavengers" in wastewater treatment plants......»»
Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typicall.....»»
Urban Birds Are Harboring Antibiotic-Resistant Bacteria
Exposure to bacteria in landfill sites and polluted rivers may explain prevalence among city-dwelling birds......»»
Could manure and compost act like probiotics, reducing antibiotic resistance in urban soils?
Urban soils often contain chemical contaminants, such as heavy metals or trace amounts of antibiotics, along with higher levels of antibiotic-resistant bacteria. New research from the University of Maryland suggests that, in some cases, boosting urba.....»»
New tools for fungicide resistance detection
Researchers at the Center for Crop and Disease Management (CCDM) have developed a new method for detecting fungicide resistance, enabling them to detect multiple mutations, both known and novel, in just one test......»»
First biogeographic map of ants reveals nine global realms
The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identif.....»»
Biocides are a useful tool to combat antibiotic resistance but appropriate use is vital, scientists suggest
A recent review in the journal Sustainable Microbiology discusses how the use of biocides can promote well-being—but must only be used when there are clear benefits......»»
Editing for resilience: CRISPR/Cas9 boosts potato stress resistance
Scientists have made a significant breakthrough in agricultural biotechnology by using CRISPR/Cas9 to edit the potato genome, resulting in plants with increased resistance to both biotic and abiotic stresses. This innovation could lead to a new era o.....»»
A review of the Epichloë festucae antifungal protein Efe-AfpA
A research team has reviewed the mechanisms behind endophyte-mediated disease resistance in strong creeping red fescue (Festuca rubra subsp. rubra) and identified the antifungal protein Efe-AfpA produced by Epichloë festucae as a key factor against.....»»
Team fabricates world"s highest-performance superconducting wire segment
Our future energy may depend on high-temperature superconducting (HTS) wires. This technology's ability to carry electricity without resistance at temperatures higher than those required by traditional superconductors could revolutionize the electric.....»»
