Crying human tear glands grown in the lab

Researchers from the lab of Hans Clevers (Hubrecht Institute) and the UMC Utrecht used organoid technology to grow miniature human tear glands that actually cry. The organoids serve as a model to study how certain cells in the human tear gland produce tears or fail to do so. Scientists everywhere can use the model to […]

‘Jumping’ DNA regulates human neurons

The human genome contains over 4.5 million sequences of DNA called “transposable elements,” virus-like entities that “jump” around and help regulate gene expression. They do this by binding transcription factors, which are proteins that regulate the rate of transcription of DNA to RNA, influencing gene expression in a broad range of biological events. Now, an […]

New method detects toxin exposure from harmful algal blooms in human urine

Blooms of toxin-producing algae exploded in both fresh and salt water ecosystems in southern Florida during the summer months of 2018, impacting wildlife and humans living in these marine environments. During harmful algal blooms, species of cyanobacteria release toxic peptides, including microcystins and nodularin into waterways. Human exposure comes from ingestion, direct skin contact, or […]
