Published Generating clean electricity with chicken feathers
(via sciencedaily.com) Original source Turning unused waste from food production into clean energy: Researchers are using chicken feathers to make fuel cells more cost-effective and sustainable.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds
(via sciencedaily.com) Original source While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Can golden retrievers live longer?
(via sciencedaily.com) Original source Researchers have found a gene associated with longevity in golden retrievers, one of the most popular breeds of dogs.
Published DNA shows where Washington culvert replacements helped spawning salmon
(via sciencedaily.com) Original source University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.
Published Imprinted genes in the 'parenting hub' of the brain determine if mice are good parents
(via sciencedaily.com) Original source Whether a mouse is a good or bad parent can be traced back to imprinted genes in key neurons in the 'parenting hub' in the brain, according to a new study.
Published Red meat consumption associated with increased type 2 diabetes risk
(via sciencedaily.com) Original source People who eat just two servings of red meat per week may have an increased risk of developing type 2 diabetes compared to people who eat fewer servings, and the risk increases with greater consumption, according to a new study. Researchers also found that replacing red meat with healthy plant-based protein sources, such as nuts and legumes, or modest amounts of dairy foods, was associated with reduced risk of type 2 diabetes.
Published Physical theory improves protein folding prediction
(via sciencedaily.com) Original source Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.
Published Restoring the function of a human cell surface protein in yeast cells
(via sciencedaily.com) Original source Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.
Published Stolen genes allow parasitic control of behavior
(via sciencedaily.com) Original source A research team has discovered that parasites manipulate their hosts using stolen genes that they likely acquired through a phenomenon called horizontal gene transfer.
Published Soft optical fibers block pain while moving and stretching with the body
(via sciencedaily.com) Original source New soft, implantable fibers can deliver light to major nerves through the body. They are an experimental tool for scientists to explore the causes and potential treatments for peripheral nerve disorders in animal models.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com) Original source Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Study elucidates evolution of mosquitoes and their hosts
(via sciencedaily.com) Original source Study creates a mosquito family tree to better understand disease transmission and host choice.
Published Single vaccine protects against three deadly strains of coronavirus
(via sciencedaily.com) Original source A vaccine designed to protect against three different deadly coronaviruses shows success in mouse studies, demonstrating the viability of a pan-coronavirus vaccine developed by researchers at the Duke Human Vaccine Institute.
Published Scientists uncover new way viruses fight back against bacteria
(via sciencedaily.com) Original source A microscopic discovery will not only enable scientists to understand the microbial world around us but could also provide a new way to control CRISPR-Cas biotechnologies.
Published New insights into the genetics of the common octopus: Genome at the chromosome level decoded
(via sciencedaily.com) Original source Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.
Published Greener neighborhoods can protect us -- at the cellular level
(via sciencedaily.com) Original source A new study finds that greenspace -- the vegetation in a neighborhood's yards, parks and public spaces -- has a positive impact on a key genetic marker associated with exposure to stress. However, the study also finds that the positive impact of greenspace isn't enough to compensate for other environmental challenges, such as air pollution.
Published Unlocking the secrets of cell behavior on soft substrates: A paradigm shift in mechanobiology
(via sciencedaily.com) Original source A research group has developed a new method for studying how cancer cells function in softer and stiffer tissue environments. This insight challenges the existing paradigm, opening up new possibilities for research in cancer biology and tissue engineering.
Published Mimicking a bird's sticky spit to create cellulose gels
(via sciencedaily.com) Original source Using a small bird's nest-making process as a model, researchers have developed a nontoxic process for making cellulose gels.
Published Whaling wiped out far more fin whales than previously thought
(via sciencedaily.com) Original source Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.
Published Critical step made for managing brushtail possums
(via sciencedaily.com) Original source Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.
