- Rabbits may breed rapidly, but not fast enough to compensate for the huge summer appetites of huge pythons roaming Florida’s Everglades.
- New mathematical and aerodynamics studies find what seems to be the optimal length for eyelashes — the length that protects best. And surprise: Longer is not always better.
- Mexican free-tailed bats can jam each other’s signals while hunting at night. The interference makes snagging an insect supper even more competitive for the flying mammals.
- By hopping, today’s kangaroos can scoot swiftly through the countryside. That was not true for some of their ancient cousins. True giants, those now-extinct kangaroos would have walked on two feet — and relied on their tippy-toes.
- When this modern ‘walking’ fish was raised on land, its body changed. How it adapted resembles some prehistoric fish. These alterations hint at evolutionary changes that may have made life on land possible.
- When koalas sprawl over a tree branch, they may not be lazy. They just might be taking advantage of some natural cooling — enough to survive a heat wave.
- The giant, Burmese pythons living in Florida’s Everglades like their adopted home. And new research shows they can find their way back to it if people try to move them somewhere else. Not all snakes will do this.
- Many animals can digest their meals without an acid-producing stomach. And research now shows they jettisoned those stomachs a long, long time ago.
- A Maryland biologist probes the unusual dining behaviors of a blood-thirsty bat.
Asian weaver ants boast not one but two superpowers: an extremely good grasp and a super quick backup strategy to keep from losing that grip during emergencies. Researchers reported their new findings in a scientific journal on February 27.
