Male fiddler crabs spend a lot of time doing this sort of thing:
This is Uca mjoebergi, a colourful crab from south Pacific shores. They're signalling to someone - but to whom?. To their own species? Their own sex? To predators?
I had fun recently giving a talk about fiddler crab signalling at a local nature center. I had seen a decent amount of research on fiddler crabs, but had never had the opportunity to review it and try to pull it into a story before. And while I was doing that, a new p........ Read more »

Too often we look for a single perfect answer to our problems.

I've been a voracious reader lately—a cookie monster of the written word. It started with Mysteries of Pittsburgh by Michael Chabon, and continued with The World Without Us by Alan Weisman (which I reviewed here) alongside The Hunger Games by Suzanne Collins (yes, I am still a young adult, thank you very much). The latest to be devoured was The Belief Instinct by Dr. Jesse Bering.

In order to release their newly assembled virions, most viruses lyse the cells that have fed and housed them. This lysis is not a haphazard affair. Some phages, for example, employ a holin-endolysin system to rupture their host's cell membrane and digest the cell wall at a precisely controlled time. (For our earlier posts about this, click here and here.) Others instead interfere with cell wall synthesis—the same strategy that we use with our β-lactam antibiotics. Now yet another completely d........ Read more »

Do supply chain strategies evolve over time? Are there the same strategic options nowadays compared to 20 years ago?
Since at least the meaning of the term logistics has evolved during the last 20 years, especially due to the emergence of supply chain management, logistics and supply chain management are used interchangeable in this article.
In 1987 Bowersox and Daugherty created a logistics strategy framework, concluding that there are basically three SC strategies:

Since the time of Linnaeus, scientists have loved classifying the world around them.

Time to continue our trek across the vesper bat cladogram. In the previous article we looked at the bent-winged bats (or miniopterids, or miniopterines): a highly distinctive, morphologically novel group that seem to have diverged from vesper bats proper something like 45 million years ago. Their distinctive nature and long history of isolation relative to other lineages conventionally included within Vespertilionidae mean that bent-winged bats are now argued by many to be worthy of 'family' s........
