Studying Meteorites May Reveal Mars' Secrets of Life

April 30, 2013 — In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the Red Planet more than a billion years ago.


And although this team's work is not specifically solving the mystery, it is laying the groundwork for future researchers to answer this age-old question.

 
The problem, said MSU geological sciences professor Michael Velbel, is that most meteorites that originated on Mars arrived on Earth so long ago that now they have characteristics that tell of their life on Earth, obscuring any clues it might offer about their time on Mars.
 
"These meteorites contain water-related mineral and chemical signatures that can signify habitable conditions," he said. "The trouble is by the time most of these meteorites have been lying around on Earth they pick up signatures that look just like habitable environments, because they are. Earth, obviously, is habitable."
 
So a good news happens, and is that scientist are almost asking the question of most of the people ask: "Can we live in Mars?"
 
Scientist and teacher form universities are making a research about possible lifes from mars by examinatind the meteorites that were landed on the red planet or mars. They stated that meteorites produces mineral and quemical molecules to make water or any other lifes that is the main things in order to humans and animals survive or live.
 
Why am I interested in this article? well, first at all, this article shows us that everything is possible if you dedicate all your life, with effort, to do what you want to do. this is an example that everything is possible, for many years, scientist and people stated that there's no proves if we can or not live in mars that it was impossible, now, today, that statement was a lie. now we can know if there is life in mars or if we can live in the red planet.
 
What is my connection with this article?  not only involve with me, but also involves with other individuals, this is a valueble lesson, Don't give up. Now, many people gives up with everything just because they feel that there's no answer or impossible to solve, including me. But with this article, I learned that with hope and effort, everything is possible, even if you think that it is hard to solve!
 
Area of interaction: Environment: This articles talk about planets, molecules, meteorites and sustainable lives.

Whale sharks use geometry to avoid shrinking

Jan. 31, 2013 — They are the largest fish species in the ocean, but the majestic gliding motion of the whale shark is, scientists argue, an astonishing feat of mathematics and energy conservation. In new research published November 25 in the British Ecological Society's journal Functional Ecologymarine scientists reveal how these massive sharks use geometry to enhance their natural negative buoyancy and stay afloat.

most animals movement is crucial for survival, both for finding food and for evading predators. However, movement costs substantial amounts of energy and while this is true of land based animals it is even more complex for birds and marine animals which travel in three dimensions.
For the past four years, Adrian Gleiss and Rory Wilson, from Swansea University, worked with Brad Norman from ECOcean Inc. to lead an international team to investigate the movements of whale sharks, Rhincodon typus, at Ningaloo Reef in Western Australia. They attached animal-borne motion sensors, accelerometers, to the free-swimming whale sharks to measure their swimming activity and vertical movement, which allowed them to quantify the energetic cost of vertical movement.

The team's data revealed that whale sharks are able to glide without investing energy into movement when descending, but they had to beat their tails when they ascended. This occurs because sharks, unlike many fish, have negative buoyancy.

Why I am interested for this article?
I wanted to be a marine biologist since I was 6 years old. And for now is one of the choices that I want to study when I get to collegue. Also is one of my favorites fish species, one of the biggest and most beautiful fishes in the world of the seas. See one of this sharks swiming is one of my dreams.


What is my contribution between this article and my life?

As I said, marine biology is one of my choices to study in the future in collegues and one day I will interact with these types of species.

Area of interaction: Environment, the animal, how they interact with their environment and how they moves, or in short word its anatomies, is considered part of the environment, natural environment

Body Language, Not Facial Expressions, Broadcasts What's Happening to Us

ScienceDaily (Nov. 29, 2012) — If you think that you can judge by examining someone's facial expressions if he has just hit the jackpot in the lottery or lost everything in the stock market -- think again. Researchers at the Hebrew University of Jerusalem and at New York University and Princeton University have discovered that -- despite what leading theoretical models and conventional wisdom might indicate -- it just doesn't work that way.


Rather, they found that body language provides a better cue in trying to judge whether an observed subject has undergone strong positive or negative experiences.
In a study published this week in the journal Science, the researchers present data showing that viewers in test groups were baffled when shown photographs of people who were undergoing real-life, highly intense positive and negative experiences. When the viewers were asked to judge the emotional valences of the faces they were shown (that is, the positivity or negativity of the faces), their guesses fell within the realm of chance.

 studies is made by scientist from colleges and universities. people can guess what is happening to the people, even thought without that people telling them what happened to him. This is called bady languages, and is known as a body code or expression that a human can understand what the other people are trying to express by not using any types of words. 

Why am I interested about this article? Body language can be related as an psychology subject. Human mind can transmit messege whichever as if you were talking, or just as an action. Psychologist and biologist are trying to find why this messeges can vary depending on the mood and the person. And my dream is to be a psychologist, and I want to involve in this type of investigation.

What is my connection my life have with this article? As I said, I want to be a psychologist, and I will going to study the mind and their languages. And also my mom studied literature and science of languages and it is interesting how human can easily know what happening to you with looking your actitude and the shape of your face. 

My area of interaction: Health an social education.This area deals with an emotional, and mind health, and also intelligence, in order to reach the perfection, and to understand more about the language of the human mind and body as well.

ScienceDaily (Oct. 30, 2012) — Cornell researchers have created an autonomous flying robot that is as smart as a bird when it comes to maneuvering around obstacles.

Able to guide itself through forests, tunnels or damaged buildings, the machine could have tremendous value in search-and-rescue operations. Small flying machines are already common, and GPS technology provides guidance. Now, Ashutosh Saxena, assistant professor of computer science, and his team are tackling the hard part: how to keep the vehicle from slamming into walls and tree branches. Human controllers can't always react swiftly enough, and radio signals may not reach everywhere the robot goes.

Scientist, have created the future, they created a flying robot, that was able to avoid obstacles by their own. Now the human mind became powerful that it can be able to build something that many people believed that was imposible to do it, and one of the thing that the people believed that it was imposible to built, was a flying robot which is able avoid obstacles.

What am I interested about this articles? Human mind can do anything, there is many secrets that even the human itself don't know what they are capable to do with it. My sciense teacher told me that, when he was a little, he didn't expected that people can make an I pad (for example) a computer or a movile phone. But now, you can see many people with their I phone, black berry, etc. What else can people make from now on?

What is my connection with this article? Simple, and not only with me, but with 8 billions of people that habits on this planet. Technology had become an important role in our lives. specially with those types of machines, that either is useful for spy, or to have fun with children and for the person self.

Area of interaction:  Human ingenuity, in this area of interaction, involves with technologies, inventions, and what the mind is capable to do.

White Shark Diets Show Surprising Variability, Vary With Age and Among Individuals


ScienceDaily (Sep. 28, 2012) — Many white sharks shift from fish to marine mammals as they mature, but individual sharks show surprising variability in dietary preferences.
White sharks, the largest predatory sharks in the ocean, are thought of as apex predators that feed primarily on seals and sea lions. But a new study by researchers at the University of California, Santa Cruz, shows surprising variability in the dietary preferences of individual sharks.
New studies had been discovered about the sharks diets. The diets of the sharks would depends at the age of the animal, the location, and the variability of the prey. Scientist thought that, the only diet of the white shark consisted in seals and sea lions. 

Why am I interested about this article? Simple, I always wanted to study marine biology and also I was interesting about the white sharks and his environments since I was 6 years old. And, now I get so amazed when I knew something that changed in the science and history of animals. I also knew that the animals, dont have a specific diets. And reading this article, I know, that there is many thing that humans dont know about the animals.

So, what is my connection between me and this article? As I said in the past paragraph, I was always interested about animals, specially with white sharks. And now, I can conclude, that we (human being), we have a lot to learn and study, and we cannot be sure about something before we dont, deeply study. 

Area of interaction: Environment, since we are talking about sharks and its diets, the way that sharks lives it can be included in this area of interaction as well.

Chimpanzees Create 'Social Traditions': Unique Handclasp Grooming Behavior Reveals Local Difference



ScienceDaily (Aug. 28, 2012) — Researchers have revealed that chimpanzees are not only capable of learning from one another, but also use this social information to form and maintain local traditions.
A research collaboration between the Gonzaga University and the Max Planck Institute shows that the way in which chimpanzees groom each other depends on the community to which they belong. Specifically, it is the unique handclasp grooming behaviour that reveals this local difference.
The specific behaviour that the researchers focused on was the 'grooming handclasp', a behaviour where two chimpanzees clasp onto each other's arms, raise those arms up in the air, and groom each other with their free arm. This behaviour has only been observed in some chimpanzee populations. The question remained whether chimpanzees are instinctively inclined to engage in grooming handclasp behaviour, or whether they learn this behaviour from each other and pass it on to subsequent generations.

What I understand is that researchers have discovered a tradition amoung chimpanzees. This social tradition consists in an unique handclasp that only several types of chimpanzee perform. Many zoologists have discovered that these types of handclasp makes them different for other chimpanzees. The handclasp done by the chimps consists in clasping its partner's hand and raising it into the air. And while they're doing that,  they use the other hand to groom each other.

What interested me about this article? Now many secrets are being discovered. One of them is the secret social tradition of the chimpanzees community. Who would expect that chimpanzees comunicate with a handclasp? No one would expect that, but now, the zoologists showed us that nothing is imposible. And we had not proven that the animals have a peculiar tradition till today. Scientist have shown that the chimpanzees have a tradition, and that tradition is transimitted from parents to their young.
What are my connection with my life with this article? I always found interesting about secrets that the animals hide. And, since we don´t talk about this in my school, I use my time to read interesting facts about the animals behaviours.

Area of interaction: Environment, althought it is talking about traditions, still it can affect the chimpanzees enviroments.
