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 New exoplanet discovered
(via sciencedaily.com) Original source Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.
Published Why orchid bees concoct their own fragrance
(via sciencedaily.com) Original source The reason why male bees collect scents in pockets on their hind legs remained a mystery for a long time. As an attractant? As a wedding gift? To show off to other males? Researchers have now figured it out.
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 A sharper look at the M87 black hole
(via sciencedaily.com) Original source The iconic image of the supermassive black hole at the center of M87 has gotten its first official makeover based on a new machine learning technique called PRIMO. The team used the data achieved the full resolution of the array.
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 M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core
(via sciencedaily.com) Original source From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.
Published James Webb Space Telescope images challenge theories of how universe evolved
(via sciencedaily.com) Original source Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.
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 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 Researchers discover tiny galaxy with big star power using James Webb telescope
(via sciencedaily.com) Original source Using new observations from the James Webb Space Telescope, astronomers looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.
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 Father's alcohol consumption before conception linked to brain and facial defects in offspring
(via sciencedaily.com) Original source Research investigating fetal alcohol syndrome (FAS) exclusively examines maternal alcohol exposure. However, because men drink more and are more likely to binge drink than women, scientists set out to challenge the existing dogma, using a mouse model to examine what happens when the mother, father and both parents consume alcohol.
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.
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.
