Published Gene editing tool could help reduce spread of antimicrobial resistance
(via sciencedaily.com) Original source A new tool which could help reduce the spread of antimicrobial resistance is showing early promise, through exploiting a bacterial immune system as a gene editing tool.
Published Deadly virus structures point toward new avenues for vaccine design
(via sciencedaily.com) Original source By comparing the structures of protein complexes from different lineages of the dangerous Lassa virus, a team identified new antibodies and vaccine targets.
Published How tasty is the food?
(via sciencedaily.com) Original source A hormone and specialized brain cells regulate feeding behavior in mice.
Published Failed antibiotic now a game changing weed killer for farmers
(via sciencedaily.com) Original source Weed killers of the future could soon be based on failed antibiotics. Researchers have found a molecule which was initially developed to treat tuberculosis but failed to progress out of the lab as an antibiotic is now showing promise as a powerful foe for weeds that invade our gardens and cost farmers billions of dollars each year.
Published Global macrogenetic map of marine habitat-forming species
(via sciencedaily.com) Original source Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.
Published New method predicts extreme events more accurately
(via sciencedaily.com) Original source A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published Study shows key role for human T cells in the control of Respiratory Syncytial Virus (RSV) infection
(via sciencedaily.com) Original source A new study has shown that human T cells have an important role to play in controlling infection.
Published Where do our limbs come from?
(via sciencedaily.com) Original source Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated.
Published Move over, armadillos: There's a new bone-plated mammal in town
(via sciencedaily.com) Original source Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.
Published A look into the heart of cellular waste disposal
(via sciencedaily.com) Original source Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific
(via sciencedaily.com) Original source Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
Published Engineers create bacteria that can synthesize an unnatural amino acid
(via sciencedaily.com) Original source Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The researchers also taught a single bacterial strain to create the amino acid and place it at specific sites within target proteins. These findings provide a foundation for developing unique vaccines and immunotherapies in the future.
Published Modular builds may help construction industry weather a perfect storm
(via sciencedaily.com) Original source Engineers have calculated the potential cost savings for builders who opt for modular construction techniques to avoid lengthy and expensive holdups caused by poor weather.
Published Previous smallpox vaccine provides immunity to mpox
(via sciencedaily.com) Original source Vaccines against smallpox given until the mid-1970s offer continuing cross-reactive immunity to mpox (previously known as monkeypox), researchers report.
Published Researchers find new mechanism for sodium salt detoxification in plants
(via sciencedaily.com) Original source A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Study may explain why high-sugar diets can worsen IBD
(via sciencedaily.com) Original source Excess sugar hampers cells that renew the colon's lining in a mouse model of inflammatory bowel disease (IBD), according to a new study that could help get to the bottom of why limiting sugary foods can ease symptoms for patients with IBD.
Published What you count is not necessarily what counts
(via sciencedaily.com) Original source Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
Published A multiomics approach provides insights into flu severity
(via sciencedaily.com) Original source Researchers were able to identify changes in the accessibility (that is, the 'readability') of transposable elements. To do this, the researchers used an approach combining various sets of multiomics data, which characterize and quantify collections of biomolecules in cells or organisms. One was the transcriptome, which consists of all copies of RNA transcribed from DNA in the cell. The other was the epigenome, which is the collection of chemical changes to DNA that modify gene expression. An advantage of this multiomics approach is that they were able to identify families of transposable elements with changes in accessibility, which would have likely been missed by previous approaches.
Published Fine particulate matter catalyzes oxidative stress in the lungs
(via sciencedaily.com) Original source Study sheds new light on the adverse health effects of air pollution: hydrogen peroxide production of fine particles may not be as important as previously assumed. A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.
