A study published in PLOS ONE reveals that nearly 60% of Anna's Hummingbirds have feather mites on their tail flight feathers, while other species show lower rates. The distribution of live mites was found to be more prevalent on outer tail feathers and often nestled between barbs.
Scientists have dissected the autophagy process in unprecedented molecular detail using live imaging and super resolution microscopy. The study reveals how the first autophagy structure forms and clarifies protein and membrane associations leading to its development into a fully-fledged autophagosome.
Scientists create high-resolution maps of samples without altering them, enabling noninvasive exploration of electrochemical phenomena and living cell membranes. This breakthrough method uses microwaves and a scanning probe to image nanoscale systems in liquids.
A new spectrometer using reflection zone plate optics resolves the spectral range of lighter elements, such as lithium and oxygen, which cannot be detected by traditional energy dispersive spectrometers. This technology has significant implications for research on energy-related materials and life sciences.
The researchers identified two transcription factors, NAC045 and NAC086, which are expressed in sieve element cells before enucleation. They also found a family of genes, dubbed NEN1-4, which act downstream of these factors. Additionally, the study revealed that control of choline transport is essential for phloem development.
Researchers at NIST have created a new type of FIB microscope that can image nonconductive materials and analyze chemical composition. The instrument uses lithium ions to produce lower-energy beams than traditional SEMs, enabling greater detail in nanostructure imaging.
