Biologists go the distance for the safe release of migratory birds

Migrating birds have embarked on treacherous voyages for hundreds of thousands of years. Yet, habitat loss and climate change might be their biggest challenge. With many species on the brink of extinction, conservation programs aim to return and sustain wild populations of the world’s most vulnerable species. Captive breeding programs must select the fittest birds to survive such a perilous flight. Researchers find that sharper wing tips might improve survival during the first migration. There’s no time for winging it.

Springtails stick the landing as the world’s tiniest acrobats

With one powerful flick of their tail, aptly-named springtails propel themselves from water to air. Though a close relative of insects, springtails can soar at heights 16 times the length of their body. No larger than a grain of rice, springtails are leaps and bounds ahead of cats when it comes to landing on their feet. Their controlled take-off, landing, and ability to right themselves in midair is unmatched and have caught the attention of scientists. These ancient acrobats may yield key innovations for robots with controlled landing.

Why are zebras striped? – Biting flies read between the lines

Why are zebras striped? A simple question with a seemingly complex answer. The stark black and white striped pattern has mystified scientists as to why the animal developed such coloration. Researchers have tested ideas from individual recognition to camouflage from predators. Perhaps the stripes help zebras avoid attacks from a much smaller predator. A recent study adds a piece to the puzzle, though this research poses more questions that leave the stripes an enigma.

Bubble, Bubble, Toil, and Trouble: Deep-sea ghost shark evolved a sixth sense

Rising from the depths of the sea, bubbles signal trouble: a confrontation between a predator and its prey. A relatively unexplored and mysterious place, the deep-sea hosts creatures that have adapted to the darkness and silence of the ocean’s floor for hundreds of millions of years. Spending so much time in these harsh conditions has forced the ghost shark to develop a sixth sense – the ability to detect changes in the electromagnetic field. Scientists are starting to uncover this ghostly tale, but much of this story remains a mystery.
