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 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 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 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 Four in five bird species cannot tolerate intense human pressures
(via sciencedaily.com) Original source In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.
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 Tracing the largest solar storm in modern times from tree rings in Lapland
(via sciencedaily.com) Original source A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
Published Adult fish struggle to bounce back in marine protected areas
(via sciencedaily.com) Original source Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.
Published With the planet facing a 'polycrisis', biodiversity researchers uncover major knowledge gaps
(via sciencedaily.com) Original source Connecting the study of infectious disease spread, biodiversity loss and climate change could offer win-win-win solutions for planetary health, but a new analysis has uncovered almost no research integrating the three global crises.
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 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 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.
Published Demand for critical minerals puts African Great Apes at risk
(via sciencedaily.com) Original source A recent study shows that the threat of mining to the great ape population in Africa has been greatly underestimated.
Published Giant phage holds promise as treatment for lung infections
(via sciencedaily.com) Original source Researchers have discovered a new bacterial killer that can target common lung infection caused by Burkholderia bacteria that has exciting potential for biotechnological applications.
Published Discovery could end global amphibian pandemic
(via sciencedaily.com) Original source A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians.
Published New discovery unravels malaria invasion mechanism
(via sciencedaily.com) Original source A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study reveals the role of a sugar called sialic acid in this invasion process. The findings have major implications for malaria vaccine and drug development.
Published Groundbreaking research in groundwater's role in ecosystem sustainability
(via sciencedaily.com) Original source Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.
Published First view of centromere variation and evolution
(via sciencedaily.com) Original source A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown scientists how greatly centromeres differ in size and structure.
