Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they need to move together as a coherent tissue while modulating the driving forces behind their movement during early development. But what happens when keratin is missing? A new study from the Institute of Science and Technology Austria (ISTA), published in Nature Communications, reveals how crucial this protein is for life itself.
Planned early birth for pregnant women with high blood pressure cuts maternal complications by nearly half and reduces the risk of stillbirth, without increasing the likelihood of caesarean section, according to a new Cochrane review.
A new study shows that Atlantic herring adapted to the Baltic Sea’s low-salinity waters through precise genetic changes that affected sperm, eggs and early embryos, offering a rare, detailed look at evolution in action.
Juvenile Chinook salmon in the Lower Fraser River estuary are feeding and growing in a slurry of contaminants from pharmaceuticals, personal care products to industrial chemicals, according to a new Simon Fraser University study.
Researchers found more than 200 contaminants in water and fish tissue samples collected from five sites in the Lower Fraser River estuary, including common blood pressure and diabetes medications, antidepressants, caffeine and cocaine.
“We’ve shown there’s a mixture of chemicals in the Lower Fraser, which not only presents potential risks to juvenile Chinook, but also other aquatic life,” says Bonnie Lo, environmental scientist and lead author of the study.
