One of the key goals in developmental and reproductive biology has been achieved this week which could have incredible implications on both this planet and others. Life has been created in a Petri dish.
In a paper published just this week in Nature, Japanese researchers have been able to grow mouse eggs entirely In vitro. Fibroblasts (skin cells which produce collagen) were reprogrammed to make eggs.
While it is true that cells have been reprogrammed to different types of cell in the past. Creating eggs is much more tricky. Eggs are the ultimate stem-cell, able to create all the bits necessary to an organism from raw genetic blueprints. They are far more flexible than stem cells.
This is very solid work and an important step in the field

This post is almost a follow from an article I wrote very recently about how climate change has severely impacted the great barrier reef via a process called coral bleaching. The article detailed the use of blue carbon in order to reduce carbon dioxide in our oceans. I finished the article with a sense of hope that if we act quickly then places such as the great barrier reef could be saved from human-mediated destruction.
However, I recently read an article found on Outsideonline.com where the first line read:
The Great Barrier Reef of Australia passed away in 2016 after a long illness. It was 25 million years old.

It is not a new idea that a mothers milk provides immune protection against a number of pathogenic agents via the transfer of antibodies, and indeed recently it was observed that the mothers immune defence plays a key role in the development of asthma and allergies in newborns and young children.
This process is known as “passive immunity”, however a team at the University of California have recently shown that breast milk can also contribute to the development of the baby’s own immune system by a process they are calling “maternal education immunity”.

The iconic and breathtakingly beautiful coral reefs that are found around the world are truly a sight to behold. They are diverse underwater ecosystems that harbour some of the worlds most fantastic, joyous and in some instances deadly species. The Great Barrier Reef (photo in set) is colossal. I’m sure that it has made the bucket list of many people, some of you reading this may have been lucky enough to have seen it for yourself. However, much like a number of Earth’s natural wonders, human agency seems to lead to its destruction..
