Published New discovery may 'unlock' the future of infectious disease and cancer treatment
(via sciencedaily.com) Original source Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and even cancer.
Published The end of genes: Routine test reveals unique divergence in genetic code
(via sciencedaily.com) Original source Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in the DNA code signalling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.
Published AI-driven earthquake forecasting shows promise in trials
(via sciencedaily.com) Original source A new attempt to predict earthquakes has raised hopes that artificial intelligence could one day be used to limit earthquakes’ impact on lives and economies. The AI algorithm correctly predicted 70% of earthquakes a week before they happened during a seven-month trial in China. The system is limited because the AI needs an extensive database and years of seismic recordings to train itself on, but researchers said the effort is nonetheless a milestone for AI-driven earthquake forecasting. Researchers will soon begin testing the system at other locations.
Published New open-source method to improve decoding of single-cell data
(via sciencedaily.com) Original source Researchers have developed a new open-source computational method, dubbed Spectra, which improves the analysis of single-cell transcriptomic data. By guiding data analysis in a unique way, Spectra can offer new insights into the complex interplay between cells — like the interactions between cancer cells and immune cells, which are critical to improving immunotherapy treatments.
Published Ruffed grouse population more resilient than expected, genetic study finds
(via sciencedaily.com) Original source Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
Published Being a vegetarian may be partly in your genes
(via sciencedaily.com) Original source A person's genetic makeup plays a role in determining whether they can stick to a strict vegetarian diet, a new study has found. The findings open the door to further studies that could have important implications regarding dietary recommendations and the production of meat substitutes.
Published Proteins roll the dice to determine bee sex
(via sciencedaily.com) Original source To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.
Published Avatars to help tailor glioblastoma therapies
(via sciencedaily.com) Original source Scientists have created a new zebrafish xenograft platform to screen for novel treatments for an aggressive brain tumor called glioblastoma, according to a new study.
Published Discovery of massive undersea water reservoir could explain New Zealand's mysterious slow earthquakes
(via sciencedaily.com) Original source Researchers working to image New Zealand's Hikurangi earthquake fault have uncovered a sea's worth of water buried in the Earth's crust. The water was carried down by eroding volcanic rocks and is believed to be dampening the earthquake fault, allowing it to release most of the pent-up tectonic stress through harmless slow slip earthquakes.
Published Honeybees are more selective in their choices for nutrition than previously thought
(via sciencedaily.com) Original source An international research group examined which plants honeybees favor when collecting nectar and pollen. The choices honeybees make have an impact on their health and also on humans, as honeybees pollinate important crop plants.
Published Ancient technology turns plant-based cheese into 'something we want to eat'
(via sciencedaily.com) Original source To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Published New pipeline makes valuable organic acid from plants -- saving money and emissions
(via sciencedaily.com) Original source In a breakthrough for environmentally friendly chemical production, researchers have developed an economical way to make succinic acid, an important industrial chemical, from sugarcane. The team has created a cost-effective, end-to-end pipeline for this valuable organic acid by engineering a tough, acid-tolerant yeast as the fermenting agent, avoiding costly steps in downstream processing. Succinic acid is a widely used additive for food and beverages and has diverse applications in agricultural and pharmaceutical products. This same pipeline can be used to produce other industrially important organic acids from crops rather than petroleum-based processes, significantly reducing greenhouse gas emissions.
Published When cells go boom: Study reveals inflammation-causing gene carried by millions
(via sciencedaily.com) Original source Researchers have found that a genetic change that increases the risk of inflammation, through a process described as ‘explosive’ cell death, is carried by up to 3% of the global population.
Published Scientists identify evolutionary gateway helping pneumonia bacteria become resistant to antibiotics
(via sciencedaily.com) Original source An evolutionary gateway which helps pneumonia cells become resistant to antibiotics has been discovered.
Published How new plant cell walls change their mechanical properties after cell division
(via sciencedaily.com) Original source Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the growth of plant organs.
Published DNA from discarded whale bones suggests loss of genetic diversity due to commercial whaling
(via sciencedaily.com) Original source Commercial whaling in the 20th century decimated populations of large whales but also appears to have had a lasting impact on the genetic diversity of today’s surviving whales, new research shows.
Published Preventing spread of parasitic DNA in our genomes
(via sciencedaily.com) Original source Researchers have identified a new enzyme called PUCH, which plays a key role in preventing the spread of parasitic DNA in our genomes. These findings may reveal new insights into how our bodies detect and fight bacteria and viruses to prevent infections.
Published Water makes all the difference
(via sciencedaily.com) Original source Water is a major driving force in the formation of separate reaction compartments within cells.
Published Genetics of attraction: Mate choice in fruit flies
(via sciencedaily.com) Original source Genetic quality or genetic compatibility? What do female fruit flies prioritize when mating? Researchers show that both factors are important at different stages of the reproductive process and that females use targeted strategies to optimize the fitness of their offspring.
Published A hygiene program for chromosomes
(via sciencedaily.com) Original source Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system.
