Time to begin anew…


I require returned to my blog after a to a high degree long period of not writing at entirely. I have been dealing with some illness and have therefore not been proficient to write or post for completely a long time. However, my strong attachment for all things spineless and sea-soldier has not diminished in this time!

I conception perhaps for a fresh start, I should introduce myself a little bit?

I am a PhD bookish man and am currently working on semaeostome jellyfish. In this blog I shall try to comprise aspects of my work and furthermore items of general interest that I perceive in my travels around the internet.

To quick spring with, if you want to perceive more about interesting invertebrate discoveries, try in this place: http://www.niwa.co.nz/intelligence-and-publications/blogs/critter-of-the-week – they regularly situation interesting invertebrate information about things found round New Zealand, Antarctica and the South Pacific, and in that place are great photographs, so it is a prosperity way of seeing and getting an idea of the diversity of invertebrates that are set up in the marine environment.

In my be in possession of work, recently I have been doing a portion of reading about jellyfish and wherefore they form blooms (i.e. then lots of the medusae appear at undivided time in one place), but some of the very interesting information I desire found out relates to how they regard many benefits to humans, and I indeed think this side of jellyfish is overlooked ~ the agency of most people, so I’m going to embrace it as my main topic today.

A bloom of Aurelia aurita

A glow of Aurelia aurita medusae, (common designation – the moon jellyfish).

Did you comprehend that some of the compounds and molecules set up in jellyfish are used in physic, the cosmetic industry, and in small room biology?

The mucins (gel-forming, glycosylated proteins) of scyphozoans be favored with multiple uses: they can be used to help some symptoms of osteoarthritis (Ohta et al. 2009), they embrace antimicrobial peptides that can potentially subsist used in the design of recent antibiotics (Ovchinnikova et al. 2006), and they take various other uses in both the pharmaceutical sector, in the same manner with biomaterial-based lubricants, and in the cosmetic sector, viewed like moisturising agents that stop cosmetics from drying confused (Pearson et al., 2011; Kim and Karadeniz, 2011). Scyphozoan venoms may likewise be useful in preventing tumour pullulation in various cancers (Orduña-Novoa et al., 2003; Balamurugan et al., 2010).

Jellyfish medusae are unruffled used as a food source in frequent eastern-Asian countries (Kitamura & Omori 2010) – be it so I’m not entirely convinced that they be the subject of a lot of flavour what with them being about 95% water! They are ofttimes dried and salted to preserve them, and on that account later rehydrated and cooked with some sort of marinade to give them a suitable flavour. Apparently they are traditionally eaten at wedding ceremonies in China. So if I am always in the Far-East (or at a dissimilar Chinese supermarket), I will be safe to try some and let you perceive!

The green fluorescent protein used in small cavity biology to highlight various aspects of cells, was isolated from jellyfish too (although from a hydrozoan called Aequorea victoria, moderately than the scyphozoans that I labor on). Here is a picture of some neurons that are marked by the protein:

This making known gained the authors involved the Nobel Prize in Chemistry in 2008. http://www.nobelprize.org/nobel_prizes/chemistry/laureates/2008/hug.html

I also think (and am definitely not alone in this) that jellyfish are the more so beautiful to look at. Here is a connect to a video of Aurelia aurita swimming in an aquarium, see what you ponder?

So, in finale I want to state that jellyfish are veritably far from the strange and dread idea that some people have of them. Yes, some of them do sting if you impress them with bare skin, but they also have many good points too, and I trust I have managed to convince you of that today?

Yours Spinelessly,

The Marine Invertebrate
