Published Software to untangle genetic factors linked to shared characteristics among different species
(via sciencedaily.com) Original source Scientists have developed a software package to help answer key questions about genetic factors associated with shared characteristics among different species.
Published How a virus causes chromosomal breakage, leading to cancer
(via sciencedaily.com) Original source Researchers describe how the Epstein-Barr virus exploits genomic weaknesses to cause cancer while reducing the body's ability to suppress it.
Published Air pollution is not just a human problem -- it's also changing the gut of British bumblebees
(via sciencedaily.com) Original source Human activity is contributing to pollution that is affecting our health. According to WHO estimates, atmospheric air pollution is estimated to cause 4.2 million premature deaths worldwide per year. Scientists and the public alike are well aware of how human activity and pollution is affecting our heath, but new research has identified how bumblebees may be caught in the crossfire.
Published Where did the first sugars come from?
(via sciencedaily.com) Original source Origin-of-life chemists propose that glyoxylate could have been the original source of sugars on the 'prebiotic' Earth
Published Hairs that help fish feel -- and humans hear
(via sciencedaily.com) Original source Scientists are reporting a discovery about unexpected asymmetry on the hair cells of zebrafish that allow them to detect movement with greater sensitivity from the back than the front.
Published First Nations populations at greater risk of severe flu, research finds
(via sciencedaily.com) Original source New research has found that First Nations populations around the world are significantly more likely to be hospitalized and die from influenza compared to non-Indigenous populations.
Published Researchers warn of tick-borne disease babesiosis
(via sciencedaily.com) Original source Scientists report the first high-quality nuclear genome sequence and assembly of the pathogen B. duncani. The team also determined the 3D genome structure of this pathogen that resembles Plasmodium falciparum, the malaria-causing parasite.
Published Biologists determine the evolutionary age of individual cell types providing critical insights for animal development
(via sciencedaily.com) Original source A research team has recently made a significant discovery about the evolutionary age of different type of cells in a small animal called Caenorhabditis elegans (C. elegans). By using single-cell transcriptomic data and refined phylostratigraphy, the team determines the transcriptomic age of individual cells, which means they are able to estimate the evolutionary origin of different cells based on the age of the genes expressed in the cells.
Published Want better kimchi? Make it like the ancients did
(via sciencedaily.com) Original source In a combined experimental and theoretical study, researchers measured carbon dioxide levels in onggi during kimchi fermentation and developed a mathematical model to show how the gas was generated and moved through the onggi's porous walls. By bringing the study of fluid mechanics to bear on an ancient technology, their research highlights the work of artisans and provides the missing link for how the traditional earthenware allows for high quality kimchi.
Published Multifunctional patch offers early detection of plant diseases, other crop threats
(via sciencedaily.com) Original source Researchers have developed an electronic patch that can be applied to the leaves of plants to monitor crops for different pathogens -- such as viral and fungal infections -- and stresses such as drought or salinity. In testing, the researchers found the patch was able to detect a viral infection in tomatoes more than a week before growers would be able to detect any visible symptoms of disease.
Published Study compares de novo proteins with randomly produced proteins
(via sciencedaily.com) Original source In a series of experiments, a team of researchers have compared de novo proteins with random-sequence proteins, looking at their stability and solubility. The results are set to advance basic research in this new field.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com) Original source Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
Published How skates learned to fly through water
(via sciencedaily.com) Original source Genes are not the only drivers of evolution. The iconic fins of skates are caused by changes in the non-coding genome and its three-dimensional structure, an international research team reports.
Published Genes are read faster and more sloppily in old age
(via sciencedaily.com) Original source Scientists have demonstrated the following findings which apply across the animal kingdom: with increasing age, the transcriptional elongation speed of genes increases, whereby the quality of the gene products suffers. With dietary restrictions, these processes could be reversed.
Published Scientists track evolution of microbes on the skin's surface
(via sciencedaily.com) Original source Researchers have discovered that Staphylococcus aureus can rapidly evolve within a single person's microbiome. They found that in people with eczema, S. aureus tends to evolve to a variant with a mutation in a specific gene that helps it grow faster on the skin.
Published Dancing in the mud: Cut cable puts an end to bacterial party
(via sciencedaily.com) Original source You can still be celebrated, even if you're buried in mud. A new study shows that innumerable other bacteria flock around cable bacteria in the oxygen-free seabed in something that looks like a dance. They apparently use the cable bacteria as an electrical lifeline for oxygen. Video recordings show that the dance stops abruptly if you cut the cable bacteria in half.
Published Study predicts poor survival rates if Ebola infects endangered mountain gorillas
(via sciencedaily.com) Original source If infected with the Ebola virus, less than 20 percent of Africa's endangered mountain gorillas would be expected to survive more than 100 days, finds a new study.
Published New approach targets norovirus, world's leading cause of foodborne infection
(via sciencedaily.com) Original source Researchers have found a creative way to make a vaccine for norovirus, the leading cause of foodborne infections, by piggybacking on rotavirus, an unrelated virus for which there are already several highly effective vaccines.
Published Light pollution may extend mosquitoes' biting season
(via sciencedaily.com) Original source A new study's finding that urban light pollution may disrupt the winter dormancy period for mosquitoes that transmit West Nile virus could be considered both good news and bad news. The good news is that the disease-carrying pests may not survive the winter if their plans to fatten up are foiled. The bad news is their dormancy period, known as diapause, may simply be delayed -- meaning they're biting humans and animals longer into the fall.
Published Stowaways in the genome
(via sciencedaily.com) Original source Scientists have discovered over 30,000 viruses by using the high-performance computer cluster 'Leo' and sophisticated detective work. The viruses hide in the DNA of unicellular organisms. In some cases, up to 10% of microbial DNA consists of built-in viruses.
