Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers      (via sciencedaily.com)     Original source 

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.

Degradation of cell wall key in the spread of antibiotic resistance      (via sciencedaily.com)     Original source 

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

Unraveling the origin and global spread of the potato blight pathogen      (via sciencedaily.com)     Original source 

A new study challenges the common theory that the devastating potato blight pathogen Phytophthora infestans originated in Mexico. Researchers meticulously reconstructed its global migration history and found it likely originated in the South American Andes before spreading globally. This research provides significant insights into the pathogen's evolutionary journey, which is crucial for developing better disease management strategies worldwide.

Melanin from cuttlefish ink as a sustainable biomass resource      (via sciencedaily.com)     Original source 

Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.

Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot      (via sciencedaily.com)     Original source 

The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.

Climate change to shift tropical rains northward      (via sciencedaily.com)     Original source 

Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.

Projected loss of brown macroalgae and seagrasses with global environmental change      (via sciencedaily.com)     Original source 

Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.

New mathematical model sheds light on the absence of breastfeeding in male mammals      (via sciencedaily.com)     Original source 

Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.

Long-standing marine mystery solved: How algae get nitrogen to grow      (via sciencedaily.com)     Original source 

Scientists shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a key role for global marine nitrogen fixation and productivity, and thus uptake of carbon dioxide. The newly-discovered bacterial symbiont is closely related to the nitrogen-fixing Rhizobia which live in partnership with many crop plants and may also open up new avenues for engineering nitrogen-fixing plants.

New deep-learning model outperforms Google AI system in predicting peptide structures      (via sciencedaily.com)     Original source 

Researchers have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides -- chains of amino acids that are shorter than proteins, but perform similar biological functions. Peptides are known to be highly flexible, taking on a wide range of folding patterns, and are thus involved in many biological processes of interest to researchers in the development of therapeutics.
