In a new study published in the Journal of Biomedical Optics, researchers from Johns Hopkins University, Mason T. Chen and Nicholas J. Durr, have proposed an end-to-end technique for accurate calculation of tissue oxygenation from single snapshots, called OxyGAN.

A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the way.

POSTECH research team led by Professor Kyong-Tai Kim uncovers the mechanism that regulates local expression of key molecules in brain development and neurodegenerative diseases.

Curbing the coronavirus pandemic relies heavily on how quickly a potentially exposed individual can be tested and quarantined. However, the current diagnostic techniques vary in reliability and relevance, so an understanding of which test is most appropriate for a given circumstance is necessary to avoid false reports. Researchers evaluated the available diagnostic techniques and determined key steps required for better testing moving forward. They present their findings in the journal APL Bioengineering.

White blood cells called cytotoxic T lymphocytes (CTLs) dig tunnels in tissues, potentially allowing other CTLs to quickly reach infected cells and tumor cells, researchers report December 1st in Biophysical Journal. The results show that some CTLs move slowly as they create channels through the extracellular matrix (ECM) - a major component of tissues. Afterward, other CTLs move quickly through the channels, presumably to efficiently search for and eliminate target cells.

Princeton University researchers have developed a new way to examine, predict and engineer interactions between multiple liquid phases, including arrangements of mixtures with an arbitrary number of separated phases.

Scientists from ICFO and University Rovira i Virgili report on a novel Raman holographic technique capable of tracking individual particles in 3D volumes from one single image.
