Experts develop way to harness CRISPR technology to deal with antimicrobial resistance
Antimicrobial resistance (AMR) is continuing to increase globally, with rates of AMR in most pathogens increasing and threatening a future in which every day medical procedures may no longer be possible and infections thought long dealt with could kill regularly again. As such, new tools to battle AMR are vitally needed.
CRISPR is promising to tackle antimicrobial resistance, but bacteria can fight back
In his presentation "How to use CRISPR-Cas to combat AMR" at the ESCMID Global Congress, Assistant Prof. Ibrahim Bitar, Department of Microbiology, Faculty of Medicine and University Hospital in Plzen, Charles University in Prague, Plzen, Czech Republic, will give an overview of the molecular biology of CRISPR technology in explaining how it can used to tackle antimicrobial resistance.

New quarantine scheme could reduce risk of rabies reintroduction in the EU following Russian invasion, study finds
Rabies is a major concern to both human and animal health, with rabies in dogs and cats widespread in Eastern Europe, and there are concerns the war in Ukraine could pose a greater risk of rabies being reintroduced to the European Union (EU). A four-month period of home isolation of dogs and cats could reduce this risk, new University of Bristol research has shown.
Optical barcodes expand range of high-resolution sensor
The same geometric quirk that lets visitors murmur messages around the circular dome of the whispering gallery at St. Paul's Cathedral in London or across St. Louis Union Station's whispering arch also enables the construction of high-resolution optical sensors. Whispering-gallery-mode (WGM) resonators have been used for decades to detect chemical signatures, DNA strands and even single molecules.
Up in smoke: New study suggests it's time to ditch long-held stereotypes about stoners
Stoners are not as lazy and unmotivated as stereotypes suggest, according to new U of T Scarborough research.
Research finds pronoun use not only shaped by language but also beliefs
Pronouns like "he" and "she" are at the center of much debate as society tries to shift to using more gender-inclusive pronouns like "they"—especially when referring to those with identities that do not fit with traditional pronouns. Research at the University of New Hampshire looked at the use of pronouns in two different languages—including one where all pronouns are identity neutral—and...
New process quickly transforms livestock manure into biochar
A technology has been developed to quickly convert livestock manure, a significant issue in animal farming, into valuable "black gold" rich in carbon within a day.
Study shows climate change impact on China's dry–wet transition zones
Climate change is significantly altering bioclimatic environments in China's dry–wet transition zones, according to a recent study published in the Journal of Hydrology.
How bad are invasive plants for birds? Research suggests large-scale removal may not have intended benefits
A prevailing opinion in land management is that non-native invasive plants are of no ecological value and they significantly diminish habitat quality for wildlife. Conservation practitioners allocate significant resources to invasive plant removal, often relying on surrounding native plants to passively fill the void. However, evidence that this practice improves food abundance or quality for...
Ridesourcing platforms thrive on socio-economic inequality, say researchers
Platforms that offer rides to passengers, such as Uber and DiDi, thrive on socio-economic inequality. By modeling the behavior of passengers and self-employed drivers, researchers of TU Delft simulated the market for ridesourcing platforms, evaluating a broad spectrum of (in)equality levels in societies.
Did Vesuvius bury the home of the first Roman emperor?
A group of archaeologists, led by researchers from the University of Tokyo, announce the discovery of a part of a Roman villa built before the middle of the first century. This villa, near the town of Nola in southwestern Italy's Campania region, was found beneath a more recent, but still ancient building from the 2nd century.
The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy that solar cells produce, the states of qubits in a quantum computer.
Umami-rich scrap fish and invasive species can liven up vegetables, says gastrophysicist
Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to "boring" vegetables. University of Copenhagen gastrophysicist Ole G. Mouritsen puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.
Florida dolphin found with highly pathogenic avian flu: Report
The case of a Florida bottlenose dolphin found with highly pathogenic avian influenza virus, or HPAIV—a discovery made by University of Florida researchers in collaboration with multiple other agencies and one of the first reports of a constantly growing list of mammals affected by this virus—has been published in Communications Biology.
A new way to study and help prevent landslides
Landslides are one of the most destructive natural disasters on the planet, causing billions of dollars of damage and devastating loss of life every year. By introducing a new paradigm for studying landslide shapes and failure types, a global team of researchers has provided help for those who work to predict landslides and risk evaluations.
Enhanced superconductivity in monolayer FeSe films on SrTiO₃(001) via metallic δ-doping
Interface engineering has been proven to be effective in discovering new quantum states, such as topological states, superconductivity, charge density waves, magnetism, etc., which require atomic-scale heterostructure fabrication. Monolayer FeSe on SrTiO3 substrates has attracted intense interest owing to its remarkable interface-enhanced superconductivity.
Imaging the microstructural landscape of amorphous carbons
Prof. Wu HengAn's team from the University of Science and Technology of China has presented six representative phases of amorphous carbons based on large-scale molecular dynamics (MD) simulations, achieving a comprehensive microstructural landscape of amorphous carbons.
Avian ambassadors and tribal perspectives: A bird's eye view of prescribed fire
PSW ecologist and tribal liaison Frank Lake wondered how the birds he grew up with in northeastern California were faring. As a Karuk tribal descendant with Yurok family, Lake has a deep connection to the land and the birds that inhabit it. Belted kingfishers, woodpeckers, condors, eagles, and other birds have been part of his ancestors' way of life for thousands of years.
Study finds affordability, not infrastructure, is major barrier to high-speed internet connectivity
With a federal subsidy that has provided less expensive or free broadband internet to more than 23 million American households due to run out of money by the end of May, a new University of Massachusetts Amherst study reveals that direct-to-consumer subsidies can be far more effective at connecting households to high-speed internet than expanding broadband infrastructure.
New algorithm cuts through 'noisy' data to better predict tipping points
Whether you're trying to predict a climate catastrophe or mental health crisis, mathematics tells us to look for fluctuations.
Researchers reconstruct landscapes that greeted the first humans in Australia around 65,000 years ago
Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this time—approximately 65,000 years ago—the first humans arrived in Sahul, a place previously devoid of any hominin species.
Will checking character references really help you find the best candidate for a job?
Finding the best person to fill a position can be tough, from drafting a job ad to producing a shortlist of top interview candidates.
Dark matter: A new experiment aims to turn the ghostly substance into actual light
A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These two qualities are reflected in its name: dark matter.
