Biodiversity is disappearing at an alarming rate as infectious diseases increasingly spill over from wildlife to humans. Disease ecologists fervently debate whether biodiversity loss leads to an increased disease risk. Now, a University of Montana researcher has published a new study with some answers.
A study detected in tumoral tissue hundreds of RNAs that do not encode proteins but appear to regulate effects of androgens and androgen receptors on gene expression in tumors. By investigating the connection between the presençe of these molecules and tumor aggressiveness, the research paves the way for new scientific approaches focusing on the transcription process of noncoding RNA.
Scientists have tried to find the safest and most effective ways to explore marine life in the oceanic water, the largest and least explored environment on Earth, for years. Each time, they were faced with the same challenge: How to capture delicate or gelatinous pelagic animals -- like jellyfish, squid, and octopuses -- without harming them? An origami-inspired device may change that.
For the first time, scientists have sequenced and analyzed the genomes of bacteria that live in anglerfish bulbs. The bacteria were taken from fish specimens collected in the Gulf of Mexico.
New fundamental complex in cells drives 'messy' form of DNA repair. In immune cells, this is crucial to make antibodies. In cancer, mutations in complex could lead to resistance to BRCA-targeting PARP inhibitor drugs or platinum chemotherapies.
A team of scientists is the first to confirm the movement patterns and seasonal migrations of baby white sharks in the north Atlantic Ocean. They put the New York Bight shark nursery theory to test by deploying satellite and acoustic tags on 10 baby white sharks (less than 1 year old) off Long Island's coast. Results provide novel insights into the distribution of this vulnerable early stage of life that complements recent work on larger white sharks.
New research from Duke University shows that neurons in the brain can carry two signals at once, using a strategy similar to multiplexing in telecommunications. The results may explain how the brain processes complex information from the world around us, and may also provide insight into some of our perceptual and cognitive limitations.
Recent articles in the journal Molecular & Cellular Proteomics investigate metabolic quirks of cancer cells, the effects of inhibiting the enzyme that generates amyloid beta, and the mechanism by which a bacterial toxin kills host cells.
The mother's microbiome, the collection of microscopic organisms that live inside us, determines the risk of autism and other neurodevelopmental disorders in her offspring, new research from the UVA School of Medicine shows. The work raises the possibility we could prevent autism by altering expectant moms' diets.
Research led by Suresh Alahari, PhD, Professor of Biochemistry and Molecular Biology at LSU Health New Orleans School of Medicine, has shown for the first time that a tiny piece of RNA deregulates energy metabolism, an emerging hallmark of cancer. The finding identifies a new target for therapeutic intervention in breast cancer.
