Published Bringing multidrug-resistant pathogens to their knees
(via sciencedaily.com) Original source Multidrug-resistant bacterial infections that cannot be treated by any known antibiotics pose a serious global threat. A research team has now introduced a method for the development of novel antibiotics to fight resistant pathogens. The drugs are based on protein building blocks with fluorous lipid chains.
Published How plants adjust their photosynthesis to changing light
(via sciencedaily.com) Original source Light supplies the energy plants need to build up biomass. A research team is researching how plants adapt their photosynthesis to changing light. They describe a key molecular mechanism that synchronizes the processes involved.
Published How mosquito larva guts could help create highly specific insecticides
(via sciencedaily.com) Original source Did you know that the world's deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico. Research reports new molecules that label proteins in the unique, alkaline environment of the Ae. aegypti digestive system that could help scientists develop insecticides to fight back.
Published Mediterranean marine worm has developed enormous eyes
(via sciencedaily.com) Original source Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. The researchers suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to finally settle an epic debate about the evolution of eyes.
Published Integrated dataset enables genes-to-ecosystems research
(via sciencedaily.com) Original source A new dataset bridging molecular information about the poplar tree microbiome to ecosystem-level processes has been released. The project aims to inform research regarding how natural systems function, their vulnerability to a changing climate, and ultimately how plants might be engineered for better performance as sources of bioenergy and natural carbon storage.
Published In the evolution of walking, the hip bone connected to the rib bones
(via sciencedaily.com) Original source A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.
Published Can language models read the genome? This one decoded mRNA to make better vaccines
(via sciencedaily.com) Original source Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published The life aquatic: A game changer for frog vision, but little difference between night and day
(via sciencedaily.com) Original source Frogs display a remarkable diversity of species as a whole, but does the same hold true for their visual abilities? A new study sought to answer this question by collaborating with researchers in Australia, Belgium, Brazil, Cameroon, Ecuador, Equatorial Guinea, French Guiana, Gabon, Seychelles, Sweden, United Kingdom and the United States, to get a sample of a diverse array of frogs to study the visual pigments found in their eyes. The researchers found this diversity is largely 'reflected' in the pigments, especially for aquatic frogs versus those living on the ground or in trees. They found little difference with the small groups of frogs that have adapted to daytime conditions as opposed to their nocturnal cousins.
Published Rusty-patched bumblebee's struggle for survival found in its genes
(via sciencedaily.com) Original source The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts.
Published Prairie voles display signs of human-like depression
(via sciencedaily.com) Original source Researchers make the case that prairie voles, small rodents that are found throughout the central United States and Canada, can be effectively used as animal models to further the study of clinical depression.
Published Shy sea anemones are more likely to survive heatwaves
(via sciencedaily.com) Original source A study shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behavior quickly.
Published New research offers insight into the future understanding of MS and its treatments
(via sciencedaily.com) Original source Researchers have developed a new and unique blood test to measure the immune response to the Epstein Barr Virus (EBV) which is the leading risk factor for developing multiple sclerosis (MS). Their findings have implications for future basic research in further understanding the biology of EBV in MS, but also has the potential to be applied in clinical trials that target the virus.
Published Heat flows the secret to order in prebiotic molecular kitchen
(via sciencedaily.com) Original source Biophysicists have demonstrated how heat flows through rock fissures could have created the conditions for the emergence of life.
Published Microbial signature of colorectal cancer-associated mutations identified in new study
(via sciencedaily.com) Original source Researchers have connected KRAS mutations in colorectal cancer to microbial signatures in the gut.
Published New tools reveal how genes work and cells organize
(via sciencedaily.com) Original source Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.
Published New sunflower family tree reveals multiple origins of flower symmetry
(via sciencedaily.com) Original source A new sunflower family tree used skimmed genomes to increase the number of species sampled, revealing that flower symmetry evolved multiple times independently, a process called convergent evolution, among the members of this large plant family.
Published Developing a vaccine for the 'zombie drug' xylazine
(via sciencedaily.com) Original source Chemical biologists design an early 'proof-of-concept' vaccine that could lead to the first effective treatment of xylazine overdose in people.
Published Evolution in action? New study finds possibility of nitrogen-fixing organelles
(via sciencedaily.com) Original source A new study finds that UCYN-A, a species of nitrogen-fixing cyanobacteria, may be evolving organelle-like characteristics.
