Jellyfish (and Fireflies too) are Helping Find the Cause of Infertility


Scientist are using illuminating genes from jellyfish and fireflies to light up cells that are producing prolactin.

Here is the Eurekalert Press Release from the University of Edinburgh...

Fireflies and jellyfish help illuminate quest for cause of infertility

Genes taken from fireflies and jellyfish are literally shedding light on possible causes of infertility and autoimmune diseases in humans

Genes taken from fireflies and jellyfish are literally shedding light on possible causes of infertility and autoimmune diseases in humans.

Scientists are using the luminescent and florescent genes to illuminate cells that produce a hormone linked to conditions, which include rheumatoid arthritis and lupus.

The technique will help scientists track the production of the hormone prolactin, which is crucial in ensuring supplies of breast milk in nursing mothers but can be overproduced by some pituitary tumours, causing infertility.

Prolactin has been linked to more than 300 biological functions. It is believed to play a role in autoimmune diseases, such as lupus and rheumatoid arthritis, as well as in the inflammation of cells and tissues.

Scientists from the Universities of Edinburgh, Manchester and Liverpool harnessed firefly and jellyfish genes, which enable these creatures to emit light, and used them to create a chemical reaction to light up cells expressing prolactin in rats.

The technique means that scientists can identify when and where prolactin is expressed to look at how the hormone works in real time.

Sabrina Semprini, whose study is published in the journal Molecular Endocrinology, said: "The lighting up of cells expressing this hormone will help us to understand its role within the body and could help research looking for treatments for conditions in which prolactin is involved."

The research, funded by the Wellcome Trust, identified cells producing prolactin throughout the body. This included the pituitary gland, the thymus – an organ in the chest which helps protect against autoimmunity – the spleen and inflammatory cells in the abdominal cavity.

Alien Stingers



http://www.alienstingers.com

The New York Aquarium has an exhibit and website on Alien Stingers (cnidarians) including jellyfish. There is information about other cool creatures like corals and anenomes. Much of the scientific information is presented at the 7th grade level so it is a little tricky for grade-schoolers but still very cool.

Jellyfish save the world from global warming

*Okay I really enjoy making headlines that are slightly deceptive and exaggerate. I am inspired by Science Insider.

There is a new household wind turbine named the Jellyfish Wind Appliance. It looks great. It is affordable and plugs right into a normal socket. Below is the information and website. Very cool stuff that could make saving the world cheaper and easier.

The Jellyfish Wind Appliance is a new class of wind turbine that is affordable, quiet, reliable and safe, and that anyone can install.

While wind power is one of the more cost effective sources of renewable energy available, few of the systems available today are either practical or affordable - turn-key systems cost thousands of dollars and are difficult to install. As a result, they lack scale, there's no killer energy app out there - until now.

By developing an affordable wind appliance that is quiet, reliable, safe and that anyone can install, Clarian hopes to enable renewable energy generation of unprecedented scale - similar to the way the PC revolutionized the computing industry. Imagine a Jellyfish Wind Appliance for every household!

Jellyfish Find the Fountain of Youth

Not only are Jellyfish taking over the world but they are immortal too. They actually can age backwards. How cool is that? Here is the link to the article in National Geographic...

Jelly Fish Take Over the World

Okay, maybe they haven't quite taken over the world but the do have quite an impact. Here is an awesome special report by the National Science Foundation.
