Environmentally Relevant Concentrations of the Flame Retardant Tris(1,3-dichloro-2-propyl) Phosphate Inhibit Growth of Female Zebrafish and Decrease Fecundity

Bioconcentrations of tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) in brain, gonad, and liver as well as effects on fecundity and development of zebrafish (Danio rerio) were determined. Zebrafish (1-month old) were exposed to environmentally relevant concentrations of 29 ± 2.1, 600 ± 21, or 6300 ± 130 ng TDCIPP/L. 201 more words


A Fishy Tale: A gene that blocks regeneration in fish blocks cancer in humans

Evolution is a fascinating thing. Over time, the human race has evolved from cavemen to a bustling civilization fueled by technology, science, and economics. While we’ve gained many abilities that separate us from other mammals and our closest ancestors, the apes, we’ve also lost a number of skills along the way. 629 more words


Are your 3D Prints Toxic?

With the rising popularity and increasing availability of 3D printers, it was inevitable that someone would start looking into the potential environmental impact presented by them. 211 more words


A love affair: Me, myself, and my research

I am a PhD student in the Brown Lab at Portland State University. I study genomic structural variation, specifically copy number variation. Copy number variation is when there is more or less than the “normal” biallelic frequency of a region of DNA. 199 more words


Influence of polyethylene microplastic beads on the uptake and localization of silver in zebrafish (Danio rerio)

This study aimed to determine whether the uptake and localization of Ag in zebrafish was affected by the presence of polyethylene microplastic beads (PE MPBs). Zebrafish were exposed to 1 μg Ag L−1 (radiolabelled with 110mAg) for 4 and 24 h in the presence or absence of PE MPBs (10, 100 or 1000 MPBs mL−1), and one treatment in which MPBs (1000 MPBs mL−1) were incubated with Ag to promote adsorption. 87 more words


Fishing for improved leukaemia treatments

To enter this year’s MRC Max Perutz Science Writing Award, MRC-funded PhD students were asked to answer the question: ‘Why does my research matter?’ Here, Tomek Dobrzycki (a PhD student in… 842 more words


Seeing the smell of rotten eggs

I’m a bit behind in writing summaries of recently published papers from my group. Here’s one that’s a few months old — I’m spurred to write now since I just learned two days ago that it got onto the cover of JACS, the flagship journal of the American Chemical Society: 630 more words
