Bacteriophage Species

A team of biologists from the Wellcome Sanger Institute, the European Bioinformatics Institute and the Universidad de los Andes has identified 142,809 species of bacteriophages — viruses that infect and replicate in bacteria — living in the human gut. Camarillo-Guerrero et al. introduce the Gut Phage Database, a collection of …

UV-Induced Photodamage

Polyphenols, a group of natural compounds found in grapes as well as other fruits and vegetables, are key compounds responsible for ultraviolet (UV)-photoprotection, according to new research. Grapes may help protect against damage to the skin caused by solar UV radiation. Image credit: Bru-nO. “Major grape polyphenols include the flavanols …

Quadruple Helix DNA

A team of scientists from the United Kingdom and Spain has demonstrated that a technique called fluorescence lifetime imaging microscopy in conjunction with a fluorescent probe can identify four-stranded ‘quadruple helix’ DNA structures within nuclei of live cells. Fluorescence lifetime imaging microscopy map of nuclear DNA in live cells stained …

Aging of Human Cells

A gene called GATA6 (GATA binding protein 6) regulates aging of human mesenchymal stem/stromal cells (MSCs), according to new research from the University of Wisconsin-Madison. When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response; by transcription factor-based cellular reprogramming, …

Human Chromosomes

A team of scientists at Harvard University has developed a new imaging technology for visualizing organization of chromatin, a substance within a chromosome consisting of DNA and protein, across multiple scales in single cells with high genomic throughput. Su et al. report a multiplexed error-robust fluorescence in situ hybridization (MERFISH)-based …

Human Proteome

In 2010, the Human Proteome Organization (HUPO) launched the Human Proteome Project (HPP), creating an international framework for global collaboration, data sharing, quality assurance and enhancing accurate annotation of the genome-encoded proteome. During the subsequent decade, the HPP scientists established collaborations, developed guidelines and metrics, and undertook reanalysis of previously …

New Organ Discovered

Our body contains a pair of previously overlooked and clinically relevant nasopharyngeal salivary glands, according to new research led by the Netherlands Cancer Institute and the University of Amsterdam. Sparing these newly-identified glands, named the ‘tubarial glands,’ in patients receiving radiotherapy may provide an opportunity to improve their quality of …

Old Human Footprints Found

An international team of archaeologists and paleoanthropologists has found ancient human and animal footprints on the surface of an ancient lakebed in the Nefud Desert, Saudi Arabia. The footprints, dated to roughly 120,000 years ago, are contemporaneous with an early Homo sapiens out-of-Africa migration and represent the earliest evidence of …
