Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the...
AI tool creates ‘synthetic’ images of cells for enhanced microscopy analysis
Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.
Illinois Study: Backyards, Urban Parks Support Bird Diversity in Unique Ways
Researchers tracked bird diversity in public parks and private backyards in twin cities in Illinois with significantly different development histories and green space management practices.
AI Weather Forecasts Captured Ciaran’s Destructive Path
Artificial intelligence (AI) can quickly and accurately predict the path and intensity of major storms, a new study has demonstrated.
The Central Apennines as a Source of CO2
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere.
Everest mountaineer’s letters digitized
Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
Liquid droplets shape how cells respond to change
New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to hyperactive signaling and tumor formation.
New compound from blessed thistle promotes functional nerve regeneration
Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have...
Invasive species sound off about impending ecosystem changes
Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of...
‘Itinerant breeding’ in East Coast shorebird species
A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'
