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…

People talk about resurrecting the Mammoth, the Dodo, the Quagga, or the Tasmanian devil, or any number of extinct (or mostly extinct) creatures. I’m all for that. I suggest removing cattle farming in Nebraska, Wyoming, Montana and adjoining areas of Canada, and repopulating the region with extinct megafauna. That would just be cool. There are…

Living a languorous life and occasionally nibbling on a jellyfish has its virtues.

Surfactant is a lipoprotein substance that is secreted by special cells located in the alveoli of our lungs. The alveoli are the grape-like structures where gas exchange happens. Without surfactant, these alveoli would collapse and prevent gas exchange. Babies born prematurely often suffer from respiratory distress syndrome because their lungs do not make enough surfactant. Now…

This is disturbing, but since civilization is ending as we speak, I suppose it is not surprising. From the Washington Post: Any resident in Florida can now challenge what kids learn in public schools, thanks to a new law that science education advocates worry will make it harder to teach evolution and climate change. The…

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…
