"Sacrifice" of virus data clears the path to open a disease discovery pipeline
Tens of millions of still-unknown or misunderstood viruses can cause diseases—including new pandemics—and affect the health of valuable terrestrial and marine environments......»»
Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
AI approach optimizes development of antibody drugs
Proteins have evolved to excel at everything from contracting muscles to digesting food to recognizing viruses. To engineer better proteins, including antibodies, scientists often iteratively mutate the amino acids—the units that are arranged in a.....»»
AI-assisted technology detects nanoplastics in water—instantly
A McGill-led research team has developed the first real-time, on-site technology capable of detecting and deciphering nanoplastics from all other particles in water, a capacity akin to being able to find a needle in a haystack within milliseconds......»»
Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors" reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought......»»
How studying bat viruses can help prevent zoonotic disease
Bats have become the poster child of emerging zoonotic disease. The creatures harbor a vast array of viruses—some of which cause deadly diseases in humans—yet they rarely get sick themselves......»»
Exploring the molecular basis of how pradimicin A binds to viral N-glycan, a potential SARS-CoV-2 entry inhibitor
HIV, Ebola and most recently, COVID-19 viruses have had an enormous impact on our societies world-wide. All these viruses are "enveloped viruses," viruses that have an exterior envelope that surrounds them largely composed of their host's cells. This.....»»
NordVPN File Checker protects users from infected files
NordVPN launches its third experimental product from the NordLabs platform. File Checker is an online tool that scans different types of files for malware and viruses. It helps to prevent malicious codes invading user’s devices through infected or.....»»
A new way to see viruses in action: Super-resolution microscopy provides a nano-scale look
A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced microscopy techniques, the researchers produced what m.....»»
New photonic crystal approach can enable sensitive and affordable detection of biomarkers
Biomarkers are small molecules of interest to researchers, because they can indicate underlying diseases, often even before symptoms even appear. However, detecting these markers can be challenging as they are often present in very low quantities, es.....»»
Scientists develop most sensitive method yet for observing single molecules
Scientists at the University of Wisconsin–Madison have developed the most sensitive method yet for detecting and profiling a single molecule—unlocking a new tool that holds potential for better understanding how the building blocks of matter inte.....»»
Detecting "Hawking radiation" from black holes using today"s telescopes
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking radiation should be obse.....»»
New metasurface-based edge detecting filter for remote sensing could transform crop monitoring
New work by researchers from the ARC Center of Excellence for Transformative Meta-Optical Systems (TMOS) and City University of New York (CUNY) published May 27 in Nature Communications realizes a new, tunable edge-detecting filter for flat-optic ima.....»»
New approach enhances accelerator"s capability to uncover clues from supernovae in lunar dust
Researchers at the China Institute of Atomic Energy (CIAE) have significantly enhanced the method of detecting iron-60 (60Fe), a rare isotope found in lunar samples, using the HI-13 tandem accelerator. This achievement paves the way for detecting 60F.....»»
Bird Flu’s Missed Clues on Dairy Farms in Texas
Detecting bird flu signs in dairy cows sooner could have helped staunch the virus's spread.....»»
Researchers develop tool for detecting foodborne pathogen that causes severe symptoms in children
The prevalence of pathogenic E. coli has meant the frequent misidentification of a similar bacterium of the Escherichia genus. E. albertii is an emerging zoonotic foodborne pathogen, first isolated in Bangladesh in 1991. Large-scale outbreaks of food.....»»
A merger of microbes: Study shows low-nutrient conditions alter viral infection
This much we know: When viruses infect bacteria—a common occurrence in oceans, soils, even human guts—the interaction results in the creation of entirely new organisms called "virocells." But scientists are still learning about how this merger of.....»»
Can disease-detecting dogs help save South Dakota"s bighorn sheep?
In summer 2021, Badlands National Park was home to a healthy and growing population of Rocky Mountain bighorn sheep, with approximately 300 total among the three herds. Then in August, Paul Roghair, lead biological science technician for the park, ca.....»»
Scientists develop new battery-free lactic acid sensor
Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source......»»
Detecting odors on the edge: Researchers decipher how insects smell more with less
