Remains of insects that lived 130 million years ago reveal how they emerged from their shell

Four pin-sized insects that lived 130 million years ago and were killed by tree resin immediately after hatching have been found in a chunk of Lebanese amber.   

The discovery marks the first ever fossilised evidence of the short-lived tool the bugs used to break free from their shell, known as 'egg bursters, according to Daily Mail'. 

Scientists aren't sure exactly how the creatures died but their rapid entrapment sheds new light on the evolutionary history of ancient bugs. 

Many modern-day insects still employ 'egg bursters' to break free of their shell but they rapidly disappear once the animal has exited. 

Small changes in oxygen levels have big implications for ocean life

 Oceanographers at the University of Rhode Island have found that even slight levels of ocean oxygen loss, or deoxygenation, have big consequences for tiny marine organisms called zooplankton, according to Science Daily .

Zooplankton are important components of the food web in the expanse of deep, open ocean called the midwater. Within this slice of ocean below the surface and above the seafloor are oxygen minimum zones (OMZs), large regions of very low oxygen. Unlike coastal "dead zones" where oxygen levels can suddenly plummet and kill marine life not acclimated to the conditions, zooplankton in OMZs are specially adapted to live where other organisms -- especially predators -- cannot. But OMZs are expanding due to climate change, and even slight changes to the low oxygen levels can push zooplankton beyond their extraordinary physiological limits.

Why deep oceans gave rise to the first complex organisms on Earth: Stable temperatures let early life forms make the best of limited oxygen supplies

For billions of years life on Earth was microscopic.

However, around 570 million years ago that all changed as complex organisms including animals with soft, sponge-like bodies sprang to life deep in the ocean.

Scientists have long been baffled as to why organisms first appeared deep in the ocean where light and food are scarce, according to Daily Mail.

A new study has found that stable temperatures were key to survival as these early lifeforms were unable to deal with fluctuations in temperature.

Meet the fastest animal on Earth - and it is not a cheetah.

Meet the fastest animal on Earth: Dracula ants snap their jaws shut at an incredible 200mph - 5,000 times faster than the blink of an eye

Meet the fastest animal on Earth - and it is not a cheetah.

The Dracula ant can snap its jaws at an incredible 200mph (320kph), which is 5,000 times faster than the blink of an eye, according to Daily Mail.

The tiny creature, just a few millimetres in size, has been officially named the fastest moving living animal, beating the cheetah, whose record running speed is 60mph (96kph).

Parrot genome analysis reveals insights into longevity, cognition

Parrots are famously talkative, and a blue-fronted Amazon parrot named Moises -- or at least its genome -- is telling scientists volumes about the longevity and highly developed cognitive abilities that give parrots so much in common with humans. Perhaps someday, it will also provide clues about how parrots learn to vocalize so well, according to Science Daily.

Morgan Wirthlin, a BrainHub post-doctoral fellow in Carnegie Mellon University's Computational Biology Department, said she and her colleagues sequenced the genome of the blue-fronted Amazon and used it to perform the first comparative study of parrot genomes.

By comparing the blue-fronted Amazon with 30 other long- and short-lived birds -- including four additional parrot species
