Researchers investigate floral development of two legume plants
The legume family (Fabaceae) is one of the largest groups of flowering plants. The Fabaceae are further divided into six subfamilies based on morphological and molecular data. Despite its diversity in floral architecture and morphology, the subfamily.....»»
Laser differential confocal Raman-Brillouin spectrum microscopy for analysis of cancer cells
There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor tissues can provide multi-dimensional information fo.....»»
Polarized imaging of dynamic light scattering to measure nanoparticle size, morphology, and distributions
A team of researchers proposed a fast and convenient method called polarized imaging dynamic light scattering (PIDLS) that quantitively evaluates nanoparticle size, morphology and distribution at the same time. A dimensionless quantity, named optical.....»»
Counting Africa"s largest bat colony with AI
Once a year, a small forest in Zambia becomes the site of one of the world's greatest natural spectacles. In November, straw-colored fruit bats migrate from across the African continent to a patch of trees in Kasanka National Park. For reasons not ye.....»»
Planting seeds: Researchers dig into how chemical gardens grow
Since the mid-1600s, chemists have been fascinated with brightly colored, coral-like structures that form by mixing metal salts in a small bottle......»»
Arachnid has three versions of "male:" How leg morphology predicts which version
Long-legged arachnids called harvestmen are "trimorphic," featuring three types of males. University of Auckland research is giving some clues as to how that happens......»»
Clever fly offers lessons on advanced predator adaptations
The saffron robber fly (Laphria saffrana) is an extremely fast bee-colored hunter that has to determine, while perched, which insects it wants to chase and eat. This is complicated by the fact that its eyes have poor resolution, especially at distanc.....»»
