John Arnst walked away from the lab bench, then returned to it to process far-flung influenza samples and wound up promoting a flu vaccine campaign for K-12 schools in North Central Florida. At one point he smashed over 200 tomatoes in two hours for a project involving Salmonella, then couldn’t bear to eat any for more than a year. He graduated from the University of Florida in 2013 with degrees in English and biology and now writes about biochemistry, public health and the people who both sometimes fail.

Researchers analyzed menthol and a compound found in chile peppers as potential treatments for this side effect of radiation therapy on head and neck cancers.
Grant-funded postdoc positions seem secure, but hiring freezes and the Trump administration’s attempts to curb immigration worry researchers ready to start new labs and PIs and committees courting talent.
A mouse embryo, with the same cells removed, was much less successful than the cow at regenerating a placenta, researchers at Hokkaido University noted.
Scientists at eight institutions in the U.S. and Europe have used a protein interaction map to identify 69 drugs that might work against SARS-CoV-2, the virus that causes COVID-19.
As new cases of the novel coronavirus appear daily, researchers in China have found that two drugs, chloroquine and remdesivir, can inhibit its replication in cell culture.
Researchers have developed a new analytical method to puzzle out which bile acids in our guts are being produced by bacteria.
The connection between what we eat and which bacteria wind up dominating our gut is well established, but a few weeks of eating nonhabitual foods are unlikely to alter the composition of your gut bacteria significantly.
Chasing the structure of a histone’s N-terminus tail. Highlighting the role of lipids in mediating endoplasmic reticulum structure. Defining the components of a bacteria’s biofilm matrix. Researchers tackle these tasks and more in our latest roundup…
Gregg Semenza is one of three physician–scientists sharing the 2019 Nobel Prize in physiology and medicine for their discoveries related to the protein complex hypoxia-inducible factor and the red blood cell–producing hormone it controls.
What is mitochondria’s role in non-alcoholic fatty liver disease? What’s the best way to differentiate embryonic and mesenchymal stem cells to use MSCs in therapy? How do fatty acids reduce melanin in tumor cells? Researchers tackle these questions …
Before Rockefeller University professor and Howard Hughes Medical Institute investigator Elaine Fuchs began her groundbreaking work studying skin-derived stem cells, she dreamed of teaching in the Peace Corps — and she still loves an adventure.
When researchers at the University of California, Riverside subjected an elusive venom to RNA sequencing and proteomic analysis, they found that its components include hundreds of identified neurotransmitter hormones and peptide precursors, they wri…
Researchers write in a paper in Molecular & Cellular Proteomics about using proteotranscriptomic techniques to uncover associations between factors expressed by high-grade serous ovarian adenocarcinoma and the likelihood of patient survival.
The levels of circulating peptides and hormones are modulated rapidly during and after exercise through a network of post-translational modifications and proteases, researchers write in Molecular & Cellular Proteomics.
Three American scientists won a 2017 Nobel Prize for discovering the mechanisms that affect myriad aspects of physiology by making our cellular clocks tick in time with the Earth’s revolutions.
Michael W. Young at the Rockefeller University and Michael Rosbash and Jeffrey C. Hall at Brandeis University have won the 2017 Nobel Prize in Physiology or Medicine for their discoveries of molecular mechanisms controlling circadian rhythm.
