Published Molecular 'Superpower' of antibiotic-resistant bacteria
(via sciencedaily.com) Original source A species of ordinary gut bacteria that we all carry flourishes when the intestinal flora is knocked out by a course of antibiotics. Since the bacteria is naturally resistant to many antibiotics, it causes problems, particularly in healthcare settings. A study now shows how two molecular mechanisms can work together make the bacterium extra resistant.
Published Different cell types in the brain are affected by tick infection
(via sciencedaily.com) Original source The dreaded tick-borne encephalitis (TBE) virus infects different types of brain cells in different parts of the brain, depending on whether the affected person's immune system is activated or not.
Published New discovery stops bacterial virus contamination
(via sciencedaily.com) Original source A new discovery could help stop bacteria being contaminated with viruses, reducing disruption and decreasing costs in industry and research.
Published Tracking a new path to octopus and squid sensing capabilities
(via sciencedaily.com) Original source Research has traced the evolutionary adaptations of octopus and squid sensing capabilities. The researchers describe for the first time the structure of an octopus chemotactile receptor, which octopus arms use for taste-by-touch exploration of the seafloor.
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 Kombucha to kimchi: Which fermented foods are best for your brain?
(via sciencedaily.com) Original source The consumption of fermented products is on the rise, and drinks like kombucha and kefir have gone viral in their popularity. But is there more to this than consumers searching for natural and healthy foods?
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 Potential new treatment for leaky gut using milk-derived extracellular vesicles
(via sciencedaily.com) Original source Milk-derived extracellular vesicles (mEVs), a type of natural nanoparticles present in bovine and human breast milk, are reported to restore gut barrier integrity, prevent leakage of bacterial toxins into the blood stream, and alleviate gut and liver disorders. mEVs are found to heal the leaky gut syndrome, which has been associated with many diseases, including inflammatory bowel disease and non-alcoholic fatty liver disease.
Published Study reveals how pollinators cope with plant toxins
(via sciencedaily.com) Original source Pollinators such as honeybees produce special enzymes that detoxify defence chemicals produced by plants, new research shows.
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 Wildfires and animal biodiversity
(via sciencedaily.com) Original source Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.
Published Professor unearths the ancient fossil plant history of Burnaby Mountain
(via sciencedaily.com) Original source New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.
Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com) Original source A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Humans, and piglets, and bears, oh my! Preventing dangerous blood clots
(via sciencedaily.com) Original source 'Don't poke the bear', they said. But that's exactly what a team of scientists have been doing, to discover the secrets of blood clotting. Hibernating bears, paralysed humans, and pigs kept in small enclosures all avoid dangerous blood clots, despite being immobile for extremely long periods.
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 Dairy foods helped ancient Tibetans thrive in one of Earth's most inhospitable environments
(via sciencedaily.com) Original source The question of how prehistoric populations obtained sustainable food in the barren heights of the Tibetan Plateau has long attracted academic and popular interest. A new study highlights the critical role of dairy pastoralism in opening the plateau up to widespread, long-term human habitation.
