Published Pinpointing coal plants to convert to nuclear energy, considering both practicality and community support
(via sciencedaily.com) Original source An assessment ranks the feasibility of converting 245 operational coal power plants in the U.S. into advanced nuclear reactors, providing valuable insights for policymakers and utilities to meet decarbonization goals, according to a new study.
Published 'Sacrifice' of virus data clears the path to open a disease discovery pipeline
(via sciencedaily.com) Original source Tens of millions of still-unknown or misunderstood viruses can cause diseases -- including new pandemics -- and affect the health of valuable terrestrial and marine environments. Now a new pipeline to investigate the 'virosphere,' or all the genomes of viruses and bacteriophages (viruses that attack bacteria) of the world, has been developed by an international collaboration.
Published Cracking open a tasty menu for captive marsupials to sink their teeth into
(via sciencedaily.com) Original source From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.
Published New way for beneficial microbes to survive extreme conditions and space exploration
(via sciencedaily.com) Original source Investigators sought to help figure out how to send materials like probiotics into space and to better treat a variety of gastrointestinal (GI) and metabolic diseases. The team's formulations allow microbial therapeutics, including those used to treat gastrointestinal diseases and improve crop production, to maintain their potency and function over time despite extreme temperatures.
Published A gut microbe could hold a key to help people benefit from healthy foods
(via sciencedaily.com) Original source In a study involving 50,000+ individuals from around the world, higher gut levels of Blastocystis, a single-celled organism commonly found in the digestive system, were linked to more favorable indicators of health.
Published Raw milk is risky, but airborne transmission of H5N1 from cow's milk is inefficient in mammals
(via sciencedaily.com) Original source While H5N1 avian influenza virus taken from infected cow's milk makes mice and ferrets sick when dripped into their noses, airborne transmission of the virus between ferrets -- a common model for human transmission -- appears to be limited. These and other new findings about the strain of H5N1 circulating among North American dairy cattle this year come from a set of laboratory experiments. Together, they suggest that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.
Published Scientists discover how to improve vaccine responses to potentially deadly bacterium
(via sciencedaily.com) Original source Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.
Published Study reveals environmental impact of artificial sweeteners
(via sciencedaily.com) Original source A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published New bio-based tool quickly detects concerning coronavirus variants
(via sciencedaily.com) Original source Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
Published Engineers find a way to protect microbes from extreme conditions
(via sciencedaily.com) Original source Researchers have now developed a new way to make microbes hardy enough to withstand extreme conditions such as heat and the manufacturing processes used to formulate the microbes into powders or pills for long-term storage.
Published Not so selfish after all: Viruses use freeloading genes as weapons
(via sciencedaily.com) Original source Certain pieces of DNA have been labeled as 'selfish genetic elements' due to notions that they don't contribute to a host organism's survival. Instead, researchers have now discovered that these elements have been weaponized and play a crucial role by cutting off a competitor's ability to reproduce.
Published Scientists map how deadly bacteria evolved to become epidemic
(via sciencedaily.com) Original source Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions -- evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behavior, a new study has found.
Published Never-before-seen view of gene transcription captured
(via sciencedaily.com) Original source New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.
Published Do genes-in-pieces code for proteins that fold in pieces?
(via sciencedaily.com) Original source A new study offers new insights into the evolution of foldable proteins.
Published Researchers uncover key mechanisms in chromosome structure development
(via sciencedaily.com) Original source Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle.
Published Retreating glaciers: Fungi enhance carbon storage in young Arctic soils
(via sciencedaily.com) Original source Melting Arctic glaciers are in rapid recession, and microscopic pioneers colonize the new exposed landscapes. Researchers revealed that yeasts play an important role in soil formation in the Arctic.
Published Pasteurization inactivates highly infectious avian flu in milk, study suggests
(via sciencedaily.com) Original source Researchers found no infectious virus in the sampled pasteurized milk products tested for H5N1.
Published Advancing toward a preventative HIV vaccine
(via sciencedaily.com) Original source A major challenge in developing a vaccine for HIV is that the virus mutates fast -- very fast. Although a person initially becomes infected with one or a few HIV strains, the virus replicates and mutates quickly, resulting in a 'swarm' of viral strains existing in a single body.
Published What was behind the 2021-2022 energy crisis within Europe?
(via sciencedaily.com) Original source A team of researchers had already been working with electricity price data for years before Russia's invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets. Their approach combines statistical physics and network science, identifying communities and the fundamental spatiotemporal patterns within the electricity price/time data from all countries. The researchers hope their work will strengthen the European perspective in the political debate about electricity markets and prices, because problems like this are best tackled via international cooperation.
