Caves are dark, dank, isolated, and home to very few plants or animals. At first glance they might seem devoid of life. But caves are full of microscopic creatures, bacteria and fungi at home in the gloom. These microbes, scientists are discovering, may be an untapped reservoir of new medicines to fight antibiotic-resistant germs.

Dam, what a find! Beaver dams could lower maximum water temperatures in streams – keeping temperature-sensitive fish safe from dangerous highs.

Previous studies suggested that beaver dams warm up the water, for example by expanding the water’s surface area, cutting the speed of water flow and removing shade by felling trees.

Genetic mutation trade-offs lead to parallel evolution
24th May 2017 phys.org | Animal Life

Organisms in nature adapt and evolve in complex environments. For example, when subjected to changes in nutrients, antibiotics, and predation, microbes in the wild face the challenge of adapting multiple traits at the same time. But how does evolution unfold when, for survival, multiple traits must be improved simultaneously?

Microbial fuel cell converts methane to electricity
19th May 2017 | sciencedaily.com | Animal Life, Earth

Transporting methane from gas wellheads to market provides multiple opportunities for this greenhouse gas to leak into the atmosphere. Now, an international team of researchers has taken the first step in converting methane directly to electricity using bacteria, in a way that could be done near the drilling sites.

Liquid-crystal and bacterial living materials self-organize and move in their own way
19th May 2017 | sciencedaily.com | Animal Life

Smart glass, transitional lenses and mood rings are not the only things made of liquid crystals; mucus, slug slime and cell membranes also contain them. Now, a team of researchers is trying to better understand how liquid crystals, combined with bacteria, form living materials and how the two interact to organize and move.

Humans set themselves apart from other animals in a number of ways, including our ability to make tools. When the anthropologist Jane Goodall discovered that wild chimpanzees frequently make and use tools, her advisor Louis Leakey famously quipped that “now we must redefine tool, redefine man, or accept chimpanzees as humans”.

Yes/no binary decisions by individual ants can lead to a rational decision as a collective when the individuals have differing preferences to the subject

Honey bees are known to “dance” with varying levels of enthusiasm depending on the quality of nectar they find. The more attractive the nectar is, the stronger they dance, appealing to other members. As a result, the majority of the members, and later the entire colony, gather to the better option.
