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 How did Earth get its water?
(via sciencedaily.com) Original source Our planet's water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth's formative years.
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 Humans need Earth-like ecosystem for deep-space living
(via sciencedaily.com) Original source Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.
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 Critical observations of sinking coasts
(via sciencedaily.com) Original source Using satellite-obtained data from 2007-21, researchers mapped the entire East Coast to demonstrate how the inclusion of land subsidence reveals many areas to be more vulnerable to floods and erosion than previously thought.
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 Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com) Original source Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Lightning strike creates phosphorus material
(via sciencedaily.com) Original source A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.
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.
Published Male yellow crazy ants are real-life chimeras
(via sciencedaily.com) Original source Researchers discovered that males of the yellow crazy ant have maternal and paternal genomes in different cells of their body and are thus chimeras.
Published Your baby's gut is crawling with unknown viruses
(via sciencedaily.com) Original source Babies tumble about with more than 200 previously unknown viral families within their intestines. This large number comes as a surprise to researchers, who closely studied the diapers of 647 Danish babies and made this mapping. These viruses most likely play an important role in protecting children from chronic diseases.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published A protective probiotic blunts the ill effects of alcohol in mice
(via sciencedaily.com) Original source A probiotic treatment reduced the negative effects of alcohol consumption in mice.
