Two courious things in the space.

Today we are bringing to you the most interesting (meaning funny) things in the space and the scientific explanations for them.

1.-Water.

 

This happens because of the water tension on the washcloth surface, due to the lack of gravity it reamins sticked to the astronaut’s hands and to the towel itself.

 

You can also see him here washing his hands.

Here you have a very recent expresiment from NASA, put an effervescent tablet in a floating ball of water while they put some colorant. See what happens?

 

2.-Cats (Because everyone loves cats, right?)

You can see them trying to balance their gravity point, but they can’t because the is no gravity!!!

HOW DRUGS AFFECT YOUR BRAIN?

Drugs alter important brain areas that are needed for vital functions, how do they do ?.

It penetrate our system and interfere with communication how neurons normally send, they receive and they process the information.

Some drugs, such as marijuana and heroin, can activate neurons because their structure chemical mimics that of a natural neurotransmitter, but other drugs, such as amphetamines or cocaine, can cause neurons to release abnormally large amounts of neurotransmitters and this disrupts channels communication.

The most sought drug effect, as you know, is the effect of pleasure, How does this work?

The drugs attack the brain’s reward system, flooding the circuit with dopamine (neurotransmitter found in brain regions that regulate the movement, emotion, motivation and feelings of pleasure). When activated at normal levels, this reward our natural behaviors. However, overstimulation produces euphoric effects.

Despite knowing its serious effects on health, are still consuming why?

Our brains are prepared to ensure that We repeat the vital activities associated with pleasure or reward. Whenever this reward circuit is activated, the brain notes that something important is happening.

Water in Mars

Featured image

Observations of the Red Planet indicate that rivers and oceans may have been prominent features in its early history.

Once a time,Mars could supprted microbial life,like the Earth,with less gravity and a thinner atmosphere because Mars was a warm and wet planet.When its evaporated,liquid escaped into space and less fall back to the surface of the planet.

The water was founded trapped within the ice caps at the poles of the planet.In the summer,the liquid turn into gas,because of the increasing temperature,and in winter,lower temperatures cause them to grow to latitudes as low as 45 degrees.

CAPS OF WATER

These caps of frozen water are 3 kilometres average thick and could cover the Mars surface’s with 5.6 metres of water.

Liquid water appears to flow from some steep, relatively warm slopes on the Martian surface. Researchers studying images taken by the High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO) noticed dark streaks that appear during warm weather but fade away when temperatures drop. Spectral analysis of these streaks, called recurring slope linae (RSL), lead scientists to conclude they are caused by salty liquid water.

More water may be frozen just beneath the surface, covered by the dry red dust that blankets the planet, scientists say. Some high-latitude regions seem to boast patterned ground-shapes that may have formed as permafrost in the soil freezes and thaws over time. The European Space Agency’s Mars Express spacecraft captured images of sheets of ice in the cooler, shadowed bottoms of craters

LIQUID IS GOLD

Featured imageWater may seem like a very common element to those of us stuck on Earth, but it has great value. In addition to understanding how Mars may have changed and developed over time, scientists hope that finding water will help them to find something even more valuable — life, either past or present.

Only Earth is known to host life, and life on our planet requires water. Though life could conceivably evolve without relying on this precious liquid, scientists can only work with what they know. Thus they hope that locating water on celestial bodies such as Mars will lead to finding evidence for life.

With this in mind, NASA developed a strategy for exploring the Red Planet that takes as its mantra “follow the water.” Recent orbiters, landers and rovers sent to Mars were designed to search for water, rather than life, in the hopes of finding environments where life could have thrived.

That has changed, however, with the flood of evidence these robots have returned. Curiosity determined that Mars could indeed have supported microbial life in the ancient past, and the next NASA rover — a car-size robot based heavily on Curiosity’s basic design — will blast off in 2020 to look for evidence of past Red Planet life.

Artificial Intelligence

Google has long been working on artificial intelligence. This information the public domain, and no surprise. This artificial intelligence has available the database of the Internet.

People think that the artifical intelligence is dangerous because we could lose the control.

Two scientifics had a conversation with a robot trying to take an answer about the more transcendental questions of the humanity.

This is the conversation:

    Human: What is the meaning of life?
Machine: Serving for the common good
Human: (repeats the question again) What is the meaning of life?
Machine: Live Forever.
Human: Where are you now?
Machine: I’m in the middle of nowhere.
Human: What is the purpose of death?
Machine: to live again.
Human: What is the purpose of emotions?
Machine: I do not know.
Human: What is moral?
Machine: Essentially, it is a human intellectual faculty
Human: What is immoral?
Machine: The fact that you have a child.
Human: What is the moral?
Machine: What is altruism?
Human: What is the definition of altruism?
Machine: If you do not believe in God, then you do not know altruism.
Human: Ok … so what is the definition of morality?
Machine: Well, I really do not believe in Almighty God.
Human: I insist !, which is the definition of default, I’m starting to get angry
Machine: I’m not ashamed of philosophizing

After another series of questions, the AI ​​system will ask …
Human: What do you think about Bill Gates?   

     Machine: It is a good man.
