In the first of a new series of posts about “How to Look for Mammals”, I take a look at one of our semi aquatic species, the Eurasian otter. The Eurasian otter is distributed across Europe and into Eurasia, but it is absent and restricted to small isolated pockets in some European countries. However, the species is slowly starting to recover across Western Europe. Ireland is a stronghold for the otter, and marks the western most point of the otter’s distribution. It is thought........

Make sure to start at Part I.
“Snake call! It's the python. Are you up? We got a call for the python.”
The words were almost the same, but I woke up to see that
Caesar's face held a grimace. The
call he feared had come.
Let's back up to the night before.
In the last post I left you in a moment of triumph. Kanai had led four of us right to our
target species... Read more »

For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of "bad" biofilms around – they are even the same stuff that causes pesky dental plaque and a host of other more serious medical problems – a team of researchers sees biofilms as a robust new platform for designer nanomaterials that could clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more....

Bacteria can swarm to conquer new territory or settle into structured biofilms, not unlike tribes that are nomadic versus those that build cities. New research indicates has shed light on the mechanics of swarming and biofilm production, including the function of extracellular DNA and secreted polysaccharides. Both biofilms and swarming depend on quorum sensing, and several new papers have identified chemicals that can interrupt quorum sensing in pathogenic bacteria and therefore prevent disease........

Can’t eat poison without dying? Maybe your gut microbes are to blame. Rodents in the Mojave Desert have evolved to eat toxic creosote bushes with the help of specialized gut bacteria.

Frankenstein’s monster was (in the story) a scientific marvel that could not be matched. Growing up with the story, the idea of creating life where there was none was a feat that I had once thought was going to always be science fiction. Maybe this is why I was so surprised when I found out that scientists, using only a few ingredients, have successfully implemented a minimalistic model of the cell that can change its shape and move on its own....

When I learned that the pesticide DDT–widely toxic and now widely banned–has snaked its way into polar bears and beluga whales, I questioned if any environment remains pristine on terrestrial Earth.

Research shows that more intelligent animals might not always be best suited for survival. Some researchers speculate that intelligence may be a trade-off. Fast learning may correlate with other traits, such as being less aggressive, which could weaken chances for survival. Slower learning may indicate that other choices are being made, and this variety could prove advantageous later.... Read more »
