Improving the way scientists can see the microscopic structures of the brain can improve our understanding of a host of brain diseases, like Alzheimer’s or multiple sclerosis. Studying these diseases is challenging and has been limited by accuracy of available models.To see the smallest parts of cells, scientists often use a technique called electron microscopy.
Pseudo-nitzschia spp., an algae that produces the neurotoxin domoic acid, can bioaccumulate within food webs causing harm to humans and animals. A molecular study of Florida’s Indian River Lagoon shows this algae was present in 87 percent of the water samples collected. All isolates showed toxicity, and domoic acid was found in 47 percent of surface water samples. As a nursery for many organisms that supports a high amount of biodiversity, the presence of domoic acid could negatively impact the lagoon system.
Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them.
In a cryo-ET experiment, scientists use a transmission electron microscope to obtain 3D images, called tomograms, of the cellular volume containing complex biomolecules.
MADISON — For the first time, researchers can get a high-resolution view of single blood stem cells thanks to a little help from microscopy and zebrafish.Researchers at the University of Wisconsin–Madison and the University of California San Diego have developed a method for scientists to track a single blood stem cell in a live organism and then describe the ultrastructure, or architecture, of that same cell using electron microscopy.
Rabies virus kills a shocking 59,000 people each year, many of them children. In a new study, researchers from La Jolla Institute for Immunology and Institut Pasteur share a promising path to better vaccine design.

One of the proteins on the virus – located on the characteristic COVID spike – has a component called the receptor-binding domain, or RBD, which is its “Achilles heel.” That is, he said, antibodies against this part of the virus have the potential to the neutralize the virus.
An international research team led by PNNL has published a vision for electron microscopy infused with the latest advances in data science and artificial intelligence. Writing a commentary in Nature Materials, the team proposes a highly integrated, autonomous, and data-driven microscopy architecture to address challenges in energy storage, quantum information science, and materials design.
Scientists at Berkeley Lab have demonstrated a new technique that could improve the performance of atomically thin semiconductors for next-generation electronics such as optoelectronics, thermoelectrics, and sensors.
The method reveals that the lattice, which forms the major structural component of the human immunodeficiency virus (HIV), is dynamic. The discovery of a diffusing lattice made from Gag and GagPol proteins, long considered to be completely static, opens up potential new therapies. The method can be applied to biomedical structure.
