New Species of Dolphin Found in Australian Waters

Oct. 29, 2013 — A species of humpback dolphin previously unknown to science is swimming in the waters off northern Australia, according to a team of researchers working for the Wildlife Conservation Society, the American Museum of Natural History, and numerous other groups that contributed to the study.

To determine the number of distinct species in the family of humpback dolphins (animals 
named for a peculiar hump just below the dorsal fin), the research team examined the 
evolutionary history of this family of marine mammals using both physical features and 
genetic data. While the Atlantic humpback dolphin is a recognized species, this work 
provides the best evidence to date to split the Indo-Pacific humpback dolphin into three 
species, one of which is completely new to science.


This article tells that there's a new dolphin Species swimming in the waters of north Australia. Its name is still being unknown. Scientists assumes that it can be related with four dolphins species: the Atlantic humpback dolphin (Sousa teuszii), which occurs in the eastern Atlantic off West Africa; the Indo-Pacific humpback dolphin (Sousa plumbea), which ranges from the central to the western Indian Ocean; another species of Indo-Pacific humpback dolphin (Sousa chinensis), which inhabits the eastern Indian and western Pacific Oceans; and a fourth Sousa species found off northern Australia. This is an advance relating with Biology and the ecosystem itself. We clearly see that there's alot of secrets on the planet and we will spend a lot of time to solve it.

Why am I interested in this article? I am always a guy who believes that nothing is true or over. I always looks for alternatives and I always believes that there's something new. In addition, I love animals, As I said before, I wanted to be a marine biologist and it is a pleasure to make my articles that it is related with animals who lives in the water.


Is there any connection between this article and my life? Yes, and it is with what is my hobby (Studying how animals interacts with the nature). Also in IB biology class, we have ecosystem as an optional subject and I would like to Study it. 

Global context: This is a continuous development. World has its secrets and we will keep growing and discovering stuff as a human and as a living thing.

Do Black Holes Have 'Hair'? New Hypothesis Challenges 'Clean' Model

Sep. 30, 2013 — A black hole. A simple and clear concept, at least according to the hypothesis by Roy Kerr, who in 1963 proposed a "clean" black hole model, which is the current theoretical paradigm. From theory to reality things may be quite different. According to a new research carried out by a group of scientists that includes Thomas Sotiriou, a physicist of the International School for Advanced Studies (SISSA) of Trieste, black holes may be much "dirtier" than what Kerr believed.

According to the traditional model, black holes are defined by only two quantities: mass and angular momentum (a black hole rotation velocity). Once their progenitor has collapsed (a high mass star, for instance, that at the end of its life cycle implodes inwards) its memory is lost forever. All that is left is a quiescent black hole, with almost no distinctive features: all black holes, mass and angular momentum aside, look almost the same.

According to Sotiriou, things may not have occurred this way. "Black holes, according to our calculations, may have hair," explains Sotiriou, referring to a well-known statement by physicist John Wheeler, who claimed that "black holes have no hair." Wheeler meant that mass and angular momentum are all one needs to describe them. 

New studies and hypothesis had been discovered about black holes. A spacetime matters that faces the gravity by cosuming everthing, Has hair. What is the significanse of the black hole having 'hair'? It could means that the black hole could not grow but the hair could and is the reason of having a magnetic power by consuming everything that they see. 

They regret most of the scientist ideas that they believed that the black hole has no hair at all such as Stephen Hawking. 

Why it is important? I love astronomy, stars planets milkyway, etc. Also it is related of what I am doing. HL/SL Biology, and someday I will study all of this. Also it is good to know what is going on in the universe, and know how to interact with all of these. 

What is the connection between me and this article? Well Is something complicated. Everytime when I do a science article, I choose something if it is related to animals or to brain health. This time I tried to make something different, something that I don't really know, such as astronomy or the black hole.

Global context: It is a Continous development. They simply keep looking and serching for what the black hole consist. And as they proove that the black hole might have hair, more hypothesis will be shown by future scientist.
