Full Cryopreservation Becoming a More Feasible Reality?

The Sci-Fi future that we thought was so far away is actually nearing and becoming more of a reality everyday. As seen in the animation show Futurama where our young protagonist Fry get frozen in a container and later he gets thawed out one thousand years later into the future, this type of freezing all though maybe not as long is looming among us. We turn to look at this concept becoming more reliable in the field of medicine when it comes to with organs for organ transplants.

One of the main problems with organ transplants is essentially like with food, organs outside of the body have a certain “Shelf life”. Because of this we are losing many organs and money trying to keep these organs only to have them lost. Part of the problem is when chilling organs the problem isn’t chilling them, but getting them rewarmed to use them in a quick manner because ice particles will form if they aren’t unfrozen fast enough and the organ will be lost. Apparently at the University of Michigan have created an innovative way to help increase the viability of the organs. nano

A solution of silica with iron coated nanoparticles seem to be the answer. Essentially how it works is that they would freeze the organs in a process called vitrification where theoretically the organs would be viable for an eternity and when you need to use them, they would use an electromagnetic field, and through the electromagnet waves the nanoparticles would be excited which is called inductive heating. And since the problem is with getting the whole organ heated, they would have the nanoparticles equally but well dispersed and because of this the whole organ would be heated at the same time.

They scaled this and tested with this up to 50 milliliters which brought back a pig’s artery but that is really far from a whole heart. They are planning to do with Rat kidneys but there is still so much to do. The other problem occurs because since the heart has many valves and chambers, dispersing them equally will be harder than a more compacted organ like a kidney so thats one obstacle they need to get around. Although we are a long way away from freezing full bodies like Fry from Futurama, we are getting closer to a future of  full cryopreservation.

New Beetle Species Discovered!

Take a second and look at the photographs above. Do you notice something particularly off or strange about this ant? Well if you fail to notice what is off with this ant, don’t be too sad, entomologist almost missed it too. In fact entomologist looking at this picture had to analyze it several times due to a pondering question of “why does this ant have two abdomens?” In fact scientist are now happy to announce that they have found a new species of beetle named: Nymphista Kronaeuri

Found on the small Latin American Country of Coasta Rica, in the rainforest they found this new species of beetle attached to and riding along an army ant. Interestingly enough this beetle has extremely strong pinches to latch up on the ant and a remarkable color which helps it camouflage against predators and even in fact the army ant that it is attached to.

These army ants in Coasta Rica, live in huge colonies that can range from hundreds to  thousands of these arthropods. However sometimes they can migrate in a nomadic sort of manner usually during the Queen Ant’s breeding season, where they travel up to 3 weeks and gather a mass amount of food in the process when the colony moves. Along with them this new species of beetles hitchhike on usually medium size worker ants that are towards the end of the colony. When the ants sleep, they usually are quite close around as well. Interestingly enough scientist aren’t exactly sure why they do this.

However what they do know is that they aren’t the only insects to do this, but seemingly they are the one and only or are few to have evolved and hide from their chauffeurs. Discoveries like this show us how much we still don’t know.
