Published Using advanced genetic techniques, scientists create mice with traits of Tourette disorder
(via sciencedaily.com) Original source In research that may be a step forward toward finding personalized treatments for Tourette disorder, scientists have bred mice that exhibit some of the same behaviors and brain abnormalities seen in humans with the disorder.
Published New vaccine effective against coronaviruses that haven't even emerged yet
(via sciencedaily.com) Original source Researchers have developed a new vaccine technology that has been shown in mice to provide protection against a broad range of coronaviruses with potential for future disease outbreaks -- including ones we don't even know about.
Published Improved nutrition, sanitation linked to beneficial changes in child stress and epigenetic programming
(via sciencedaily.com) Original source A new study provides some of the clearest and most comprehensive evidence to date on what is known about stress physiology and 'epigenetic programming.'
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published Genomes of 'star algae' shed light on origin of plants
(via sciencedaily.com) Original source Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
Published How E. coli get the power to cause urinary tract infections
(via sciencedaily.com) Original source New research examines how the bacteria Escherichia coli, or E. coli -- responsible for most UTIs -- is able to use host nutrients to reproduce at an extraordinarily rapid pace during infection despite the near sterile environment of fresh urine.
Published Source of pregnancy complications from infections revealed by placenta map
(via sciencedaily.com) Original source The placenta's response to infections from malaria, toxoplasmosis and listeria has been mapped in high resolution, possibly paving the way for new treatment options.
Published New discovery of a mechanism that controls cell division
(via sciencedaily.com) Original source Researchers have discovered that how a special protein complex called the Mediator moves along genes in DNA may have an impact on how cells divide. The discovery may be important for future research into the treatment of certain diseases.
Published Novel chemical tool for understanding membrane remodeling in the cell
(via sciencedaily.com) Original source Researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell. The findings lead to a deeper understanding of how membrane remodeling works in human cells and future development of new drugs.
Published New eco-friendly lubricant additives protect turbine equipment, waterways
(via sciencedaily.com) Original source Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Published For microscopic organisms, ocean currents act as 'expressway' to deeper depths
(via sciencedaily.com) Original source Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Oil palm plantations are driving massive downstream impact to watershed
(via sciencedaily.com) Original source The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.
Published Scientists track 'doubling' in origin of cancer cells
(via sciencedaily.com) Original source Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study
(via sciencedaily.com) Original source Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published Deeper understanding of malaria parasite development unlocks opportunities to block disease spread
(via sciencedaily.com) Original source Natural malaria infections have been genetically analysed at a higher resolution than ever before, giving insights that could help understand and block transmission.
Published Promising new treatment strategy for deadly flu-related brain disorders
(via sciencedaily.com) Original source Researchers have found that a brain disorder associated with flu (influenza-associated encephalopathy, or IAE) can be caused by the influenza virus entering the brain from the blood via endothelial cells. In these cells, the researchers observed viral protein accumulation, suggesting that antivirals targeting viral transcription/translation may be useful treatments for some patients. Given the lack of effective treatments for IAE, this finding will likely improve patient care and reduce IAE-related deaths worldwide.
Published Activation of innate immunity: Important piece of the puzzle identified
(via sciencedaily.com) Original source Researchers have deciphered the complex interplay of various enzymes around the innate immune receptor toll-like receptor 7 (TLR7), which plays an important role in defending our bodies against viruses.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet
(via sciencedaily.com) Original source Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published When good bacteria go bad: New links between bacteremia and probiotic use
(via sciencedaily.com) Original source Researchers discovered a concerning association between bacteremia and probiotic use, particularly with Clostridium butyricum (C. butyricum) MIYAIRI 588. Whole-genome sequencing revealed that all C. butyricum bacteremia strains were probiotic derivatives. Out of 6,576 cases of positive blood cultures, C. butyricum was detected in only five cases, all derived from probiotics. The study underscores rare but serious adverse events linked to probiotics, advocating cautious prescribing practices, especially for hospitalized patients.
