Published Engineering viruses to kill deadly pathogens
(via sciencedaily.com) Original source Antimicrobial resistance is an urgent and growing global crisis. Researchers are exploring phages, viruses that infect bacteria, as a possible solution. In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. The process can also be used to produce more phage variants for further exploration.
Published When and how immune cells decide to form pathogen memories
(via sciencedaily.com) Original source During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection.
Published Using computers to design proteins allows researchers to make tunable hydrogels that can form both inside and outside of cells
(via sciencedaily.com) Original source New research demonstrates a new class of hydrogels that can form not just outside cells, but also inside of them. These hydrogels exhibited similar mechanical properties both inside and outside of cells, providing researchers with a new tool to group proteins together inside of cells.
Published Researchers craft new way to make high-temperature superconductors -- with a twist
(via sciencedaily.com) Original source An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.
Published A green alternative for treating Streptococcus iniae bacteria in hybrid striped bass
(via sciencedaily.com) Original source Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.
Published Superfluids could share characteristic with common fluids
(via sciencedaily.com) Original source Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. However, this Reynolds similitude does not apply to quantum superfluids. A researcher has theorized a way to examine the Reynolds similitude in superfluids, which could demonstrate the existence of quantum viscosity in superfluids.
Published DNA particles that mimic viruses hold promise as vaccines
(via sciencedaily.com) Original source Using a DNA-based delivery particle, researchers created a vaccine that can induce a strong antibody response against SARS-CoV-2.
Published Small yet mighty: Showcasing precision nanocluster formation with molecular traps
(via sciencedaily.com) Original source Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing NCs is, however, usually challenging. Now, scientists have demonstrated functional NC formation with atomic-scale precision. They successfully grew cobalt NCs on flat copper surfaces using molecular arrays as traps. This breakthrough paves the way for advancements like single-atom catalysis and spintronics miniaturization.
Published Resin destroys coronavirus from plastic surfaces
(via sciencedaily.com) Original source Researchers are currently developing anti-viral surfaces to decrease the spread of infectious diseases. A recent study found that a resin ingredient is effective against coronaviruses and strongly decreases their infectivity on plastic surfaces.
Published Tomato juice's antimicrobial properties can kill salmonella
(via sciencedaily.com) Original source New research shows that tomato juice can kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health.
Published Gut microbiota influence severity of respiratory viral infection
(via sciencedaily.com) Original source The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections.
Published 'Genomic time machine' reveals secrets of our DNA
(via sciencedaily.com) Original source Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.
Published Scientists pull off quantum coup
(via sciencedaily.com) Original source Scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
Published Probiotics promote weight loss in obese dogs
(via sciencedaily.com) Original source New research demonstrates how probiotics can reshape the gut microbiome and energy metabolism in dogs.
Published Researchers control biofilm formation using optical traps
(via sciencedaily.com) Original source Researchers showed that biofilm formation can be controlled with laser light in the form of optical traps. The findings could allow scientists to harness biofilms for various bioengineering applications.
Published Cosmic building blocks of life discovered through the electron microscope
(via sciencedaily.com) Original source Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.
Published How obesity dismantles our mitochondria
(via sciencedaily.com) Original source Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.
Published Researchers map genome for cats, dolphins, birds, and dozens of other animals
(via sciencedaily.com) Original source Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Published Soap bark discovery offers a sustainability booster for the global vaccine market
(via sciencedaily.com) Original source A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry.
Published Dragonfly wings used to study relationship between corrugated wing structure and vortex motions
(via sciencedaily.com) Original source Scientists undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that corrugated wings exhibit larger lift than flat wings.
