Written for the prompt: What is the most important fundamental mystery in biology today that, if unlocked by basic research, would yield the greatest dividends for human health? Poop. This ubiquitous, noxious substance provokes an instinctive reaction of disgust, and for good reason – it harbors deadly pathogens. Despite the near-universality of poop and fart jokes, humans have spent much …
Clade Killers II: Things Fall Apart
There is something special about the body. Without a well-defined body, it is difficult to actualize a self in humans. Even for non-human animals, we cannot help but anthropomorphize their endless forms most beautiful into arms and legs and heads – another living self. One of the most horrifying things about sea star wasting disease (SSWD) is the utter distintegration of an …
Clade-Killers I: An Elegy for the Bats
Years since detection. Infected species. The number of infected US states and Canadian provinces. The ever-increasing body count. The unsustainably high mortality rates (Frick et al. 2010). In some ways, the statistics are sterilizing, objective, and easier to deal with than the stark reality of empty caves, absent roosts, and the silent spring and summer nights. But the numbers are just …
Love your bugs
Featured image from Kelly Brogan As much as you may want to, you can’t escape germs. In fact, it’s probably better if you don’t. Humans are populated by a rich community of about 100 trillion microbes, 10 times as many cells as we have in our bodies, and weighing an estimated 3 pounds (the weight discrepancy is due to the larger size of human …
Spectacular Symbiosis: Leafcutter Ants pt. 1
Of all the animals with which we have the honor of sharing the world, leafcutter ants have to be amongst the most impressive. Over the last ~50 million years, the 47 species of leafcutter ants have achieved remarkable evolutionary success, extending their range from Mexico to Argentina. They are the dominant herbivores in the tropical Americas, and can be major agricultural pests, stripping small trees of their …
Spectacular Symbiosis: A Few Good Viruses
Viruses are one of the last great biological bogeymen facing modern humans. Fire, weapons, and a changing climate have tamed or killed off our ancient predators. For those lucky enough to have access to them, antibiotics have won a long, though fragile and temporary, reprieve from bacterial infections. However, the prospect of a new viral outbreak, for which we do …
A bacterium with many hats
Since I tend to be a one trick pony and like to tie my blog topics back to my current interests, I’m going to write about Helicobacter pylori, the bacterial species that I am studying. H. pylori is fascinating to me because it’s a big intellectual puzzle; we haven’t determined specifically how it’s transmitted between humans, whether it’s an important gut microbe …
