The first mini live heart printed in 3D and made with human tissue and veins

Corazón impreso 3D.

SUMMARY

A team of researchers created a living heart using human tissue and a 3D printer for the first time. That heart is alive and beats, it was made with cells and biomaterials from a patient. It's very little, around three centimeters, but is possible to make a bigger one.

This discovery was carried out by a group of scientists from the University of Tel Aviv, in Israel. The cells created, were reprogrammed to be stem cells, and then differentiated, so there were heart cells and blood vessels cells.

Finally, another advantage will be that they wouldn't cause any rejection as they are generated from the patient's tissue. So they would be compatible with the patient at the immunological, cellular, biochemical and anatomical level.

COMENTARY

After reading this new I thought, "that's impossible, and artificial heart made with a 3D printer? No, that's a joke. As, a few years later I heard from a 3D printer, and that was like, "wow!", but now a functional heart made with that...

Well, the science will never cease to amaze us, but a part of that, that discovery is excellent, is a perfect way to save a lot of lifes. The heart is an organ that can't be transplanted and this allow to bring a new heart to people that needed.

Also, it's true that it isn't so easier, we need a bigger heart adapted to our needs, but that's a big step for the future medicine. So I think that we must investigate more, maybe testing with animals and don't stop until we've found the solution.

Criptozoología Alex Lapuerta

Criptozoología La criptozoología significa literalmente: 'el estudio de los animales ocultos' y es una pseudociencia que se ocupa de la búsqueda de animales cuya existencia no ha sido probada. Los animales de interés criptozoológico son llamados «críptidos», término creado por John Wall en 1983. Esto incluye a especímenes vivos de especies extintas, como algunos dinosaurios, animales que carecen de evidencia pero aparecen en mitos y leyendas, como Piegrande, el Chupacabras o el Monstruo del lago Ness; y animales salvajes lejos de sus zonas geográficas, como gatos fantasma. La criptozoología no es una rama reconocida de la zooligía ni de ninguna otra disciplina científica. Es un ejemplo de pseudociencia debido a que confía fuertemente en pruebas anecdóticas, relatos y supuestos avistamientos.

Hallan animales bajo un kilómetro de hielo en la Antártida - Resumen El equipo de científicos que ha perforado un kilómetro de hielo sobre el lago Mercer, a 600 kilómetros del polo sur, en la Antártida. Los investigadores hicieron este descubrimiento cuando examinaron algunos sedimentos situados bajo el lago. Allí encontraron restos de algas que vivieron hace millones de años cuando la Antártida era mucho más cálida y de animales mucho más recientes. Entre ellos hallaron carcasas de tardígrados u osos de agua, un pequeño crustáceo similar a una gamba y zarcillos quizás procedentes de una planta o de un hongo. - Fuente https://www.abc.es/ciencia/abci-hallan-animales-bajo-kilometro-hielo-antartida-201901182148_ noticia.html#ns_ campaign=mod-outbrain&ns_mchannel=abc.es&ns_source=organico&ns_linkname= desktop-tablet&ns_fee=AR23_1fila - Fecha de publicación                                                                                   19

THE BONOBAS HELP THEIR CHILDREN TO FLIRT SUMMARY Most mothers of mammals take care of their children until they reach adulthood, when they become detached from them or become independent. But with the bonobas the concern goes further; they take care that their children mate, even stopping the attemps of other males. Bonobo moms are capable of everything for make their children parents. When their childs try to mate and another males prevent it, mothers chase away these males. After several years of observing four groups of bonobos that inhabit the "Congolese jungles, the authors of the study found that where the mother is present, adult children are up to 3,14 times more likely to be parents than other males. However, the bonobas do not do the same with their daughters. Despite several years of investigation, the scientists didn't detect behaviours that facilitate their mating.
