Nanocrystals cooled by a laser emit a reddish-green'glow '
As they are cooled by a laser, nanocrystals, emit a reddish-green "glow" that can be seen by the naked eye. Researchers at the University of Washington used an infrared laser to cool water by about 36 degrees Fahrenheit -- a major breakthrough in figuring out how to make a laser refrigerate water ...This is an NSF Multimedia Gallery item.

Nanoparticle may replace biopsy needles in transplant organ rejection (Image 1)
A T cell (in violet) makes contact with a transplant organ cell (in brown and purple). The T cell secretes the enzyme granzyme B (in gray), which attacks the organ cell. But granzyme B also severs fluorescent signal molecules (in green) from the rejection-detecting nanoparticle (light red). The ...This is an NSF Multimedia Gallery item.

Researchers say photoluminescence is phenomenon that triggers emissions (Image 2)
Rice University researchers argue that photoluminescence, rather than Raman scattering -- the elastic scattering of a photon by molecules that are excited to higher energy levels, gives gold nanoparticles their remarkable light-emitting properties. Their techniques could be used to develop solar ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Alpacas: More than just for sweaters -- a new medical advance.
Mini-antibodies found in the blood of camels, alpacas and llamas, shrunk further to create so-called "nanobodies," may help solve a problem in the cancer field: making specific types of T-cell therapies work in solid tumors. Scientists used these nanobodies -- which resemble antibodies in human ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

NIH Director's Seminar: Imaging the nanoscale structure of endocytosis with correlative super-resolution light and electron microscopy
NIH Director's Seminar Series
The plasma membrane separates the cell ’ s interior from the outside world. The exchange of signals and material across this barrier is regulated by a multitude of channels, transporters, receptors, and trafficking organelles. Mapping the molecular structure and dynamics of the plasma membrane is key to understanding how human cells function in health and malfunction in disease. Electron microscopy can produce high resolution images of the membrane. Historically, it has been challenging to locate and identify proteins within these images. Recently-developed super-resolution localization micr...

Biowulf 20th Anniversary Symposium: Telomere-to-telomere assembly of a complete human X chromosome
Biowulf Seminar
Release of the first human genome assembly was a landmark achievement, and after nearly two decades of improvements, the current human reference genome (GRCh38) is the most accurate and complete vertebrate genome ever produced. However, no one chromosome has yet been finished end to end, and hundreds of gaps persist across the genome. These unresolved regions include segmental duplications, ribosomal rRNA gene arrays, and satellite arrays that harbor unexplored variation of unknown consequence. We aim to finish these remaining regions and generate the first truly complete assembly of a human genome.
Here we...
