Dr. Michael Tobler and Dr. Zach Culumber at Kansas State University examined 112 species of live-bearing fish (Poeciliidae) and have made some interesting discoveries about their evolution. Their analyses included information on body shape, fin size, where the species are found and information on global climate. What they discovered is that the evolution of female fish is…

  Preeclampsia is a serious complication that develops in about 5-8% of pregnant women. It is characterized by elevated blood pressure and is typically accompanied by excess protein in the urine (a sign of kidney problems). Symptoms often (but not always) return to normal after delivery of the baby. Elabela is a recently discovered micropeptide secreted by the placenta in…

Humans are not the only primates that spontaneously develop hypertension. A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, examined the development of spontaneous hypertension in African Green Monkeys (Chlorocebus aethiops sabaeus; aka: vervets). The team measured blood pressure in 424 adult monkeys and found that 37% had…

Platelets are important in the formation of blood clots. For this reason, antiplatelet medications are commonly prescribed for people at risk of developing blood clots, or who have already developed one. Many of the medications that are currently on the market to treat blood clots come with a risk for excessive bleeding and reduced platelet numbers.…

A recent study published in Microbiome from researchers at the University of Alberta shows that babies from families with pets had nearly two-fold increases in the amount of two specific microbes in their guts, Ruminococcus and Oscillospira. These particular microbes are associated with reduced risks of developing childhood allergies as well as obesity. According to study author…

How bird eggs got their shape

Ever wonder why bird eggs are shaped the way they are and what drives the variations in egg shapes across species? I never really wondered that either until I saw an article in Science that explained a possible reason…then I just HAD to know. Some theories had been proposed suggesting that their shape prevented eggs from…

Who would have thought tiny fish could lead to big advances in medicine? Zebrafish (Danio rerio) and mammals have similar anatomy and physiology of the brain, eyes, gut, and cardiovascular systems. Some of the reasons why these fish are good models to understand cardiovascular physiology were recently explored in a new article published in Physiological Reviews.…

Most of us have heard the phrase: Laughter is contagious. When we hear other people laughing, we often smile even if we have no idea why they are laughing. Dr. Sophie Scott from the University College of London and her colleagues played both positive sounds (like laughter) and negative sounds (like retching or screaming) to subjects and…

Greek yogurt boom relies on low-wage Mexican, Guatemalan immigrants in New York

My afternoon snack of a Chobani yogurt comes from New York State’s $14 billion dairy industry. The state leads the country in Greek yogurt production. Interviews with 88 dairy parlor workers describe low wages, injuries, and poor housing and a call for companies to adopt strong labor codes of conduct.

Swedish Academia Is No Meritocracy

After almost 14 mostly dismal years on the academic job market, I find it a consolation to read an opinion piece in Times Higher Education under the headline “Swedish Academia Is No Meritocracy“. In my experience this is also true for Denmark, Norway and Finland. In Norway, for instance, the referee board that evaluates job…
