Missing mineral found in algae
ANU_-_dolomite_algae

The century-old mystery of a missing mineral in coral reefs has been solved by a team from The Australian National University. 
The team, led by Dr Bradley Opdyke of the Research School of Earth Sciences, has uncovered a hidden stash of the mineral dolomite in coral reefs around the globe, ending a search that has lasted over 100 years. The discovery was published in November’s Biogeosciences. 

“For over a century scientists have puzzled over the ‘dolomite problem’ – the mystery surrounding the abundance of dolomite in fossil reefs and its apparent absence from modern reefs,” said Dr Opdyke. 

“We have discovered that dolomite is in fact present in large quantities in modern coral reefs, but from an unexpected source.” 

The team’s eureka moment came when they found large quantities of dolomite packed inside a ‘reef builder’ species of red algae, Hydrolithon onkodes. 

“There was dolomite on the reefs all along, but it was hidden within these algae,” said Dr Opdyke...

Mitochondria were ‘parasites’
Raycat_-_mitochondrion

A bacterium whose name was inspired by the Star Wars films has provided new clues into the evolution of our own cells and how they came to possess the vital energy-producing units called mitochondria.
The University of Sydney research investigated the bacterium Midichloria mitochondrii- named after helpful Star Wars microbes, called Midi-chlorians, that live inside cells and grant the mystical power known as The Force. It has revealed that mitochondria may have entered our cells though a parasitic bacterium that used a tail to swim and could survive with almost no oxygen.

The work, published in this month's issue of Molecular Biology and Evolution, challenges traditional explanations of how the ancestors of mitochondria first entered our cells between one and a half and two billion years ago. It also sheds new light on a process recognised as one of the major transitions in the history of life on earth.

"Our results challenge the paradigm - shown in every biology textbook - that mitochondria were passive bacteria gobbled up by a primordial cell," says co-author Dr Nathan Lo from the University of Sydney's School of Biological Sciences....

Ah, I see. Your link is so generic that I didn't catch it. I never would have posted it if I knew. Sorry.Cry
Even though my link is prettier, just delete it as yours was posted first. Thumbs Up
