Earth's tilt affects climate change
In a first, researchers have discovered a connection between the Earth's tilt, called obliquity, that shifts every 41,000 years, and the movement of a low pressure band of clouds that is the Earth's largest source of heat and moisture - the Intertropical Convergence Zone, or ITCZ.
 
This finding showed that the Earth's tilt plays a much larger part in ITCZ migration than previously thought, which, the study said, would enable climate scientists to better predict extreme weather events. 
 
For the study, the researchers analysed data from the past 282,000 years.
 
"I took the data and put it through a mathematical prism so I could look at the patterns and that is where we see the obliquity cycle, that 41,000-year cycle," said Kristine DeLong, associate professor at Louisiana State University in the US.
 
Historically, the collapse of the Mayan civilization and several Chinese dynasties have been linked to persistent droughts associated with the ITCZ. 
 
This new information is critical to understanding global climate and sustainable human socioeconomic development, the researchers said.
 
With research collaborators at the University of Science and Technology of China and National Taiwan University, DeLong looked at sediment cores from off the coast of Papua New Guinea and stalactite samples from ancient caves in China. 
 
DeLong's data analysis revealed obliquity in both the paleontological record and computer model data. 
 
The research was published in the journal Nature Communications.

tilt, not tile. Sorry. And any not ant.

There was a movie a long time ago, that showed the changes of the Earth's tilt. Purple skies and things like that.

A 1% tile is devastating. It can alter the way the species adapt and conform. The movie talked of massive nuclear explosions that caused the tilt. Exaggerated. More likely are the internal disturbances, tectonic shifts, earthquakes that follow and the location. The nearer the poles, more the shift. Asteroids may also affect but at the poles the hit may be a glancing one; and the equatorial hit, or close to that, may cause massive internal shifts.

The tilt can be in ant one of 360 degrees, or part thereof. The results are hard to guess as no one can be sure of which way the wind will blow.

Anyway, why worry. We still have a few million years to go. Or it may be tomorrow. Who knows?

To end. A joke.

A professor speaks of the earth ending 50 billion years from now. An agitated and nervous listener jumps up and asks, "Will you please repeat that?". The speaker does. The man wipes his forehead, lets out a sigh of relief and says, "Whew. I thought you said 15 billion".

Arnold Schwarzenegger may not be part of 'Enthiran 2'
 "The Terminator" star Arnold Schwarzenegger, who was approached by the makers of superstar Rajinikanth-starrer "Enthiran 2" to play the antagonist in the film, may not get to play the role as the deal failed to work out, a source has said.
 
"The team has finally decided to rope in a Bollywood actor to play the baddie. The deal with Arnold Schwarzenegger didn't work out for various reasons. Hence, the makers decided to move on as the project was getting delayed," a source from the film's unit told IANS.
 
One of the reasons why the deal with Schwarzenegger fell through was because of the star's high remuneration of Rs.120 crore, according to the source,
 
A sequel to Tamil blockbuster "Enthiran", the film also stars Amy Jackson, who will reportedly be playing a robot.
 
To be directed by Shankar and produced by Lyca Productions, the project is set to go on floors later this month or early next year.
 
Oscar winning composer A.R. Rahman has been roped in to create music for the film.

Time to become a NASA astronaut and fly to Mars
Want to become an astronaut and fly to Red Planet? NASA is now accepting applications for future explorers and the final selection list will be announced in mid-2017.
 
Those chosen may fly on any of four different US spacecraft during their careers - the International Space Station (ISS), two commercial crew spacecraft currently in development by the US companies and NASA’s Orion deep-space exploration vehicle to Mars.
 
"NASA is on an ambitious journey to Mars and we’re looking for talented men and women from diverse backgrounds and every walk of life to help get us there,” said NASA administrator and former astronaut Charles Bolden in a statement.
 
"Today, we opened the application process for our next class of astronauts, extraordinary Americans who will take the next giant leap in exploration. This group will launch to space from US soil on American-made spacecraft and blaze the trail on our journey to the Red Planet,” he added.
 
NASA astronauts will again launch to the International Space Station (ISS) from Florida’s Space Coast on American-made commercial spacecraft -- Boeing’s CST-100 Starliner and the SpaceX Crew Dragon.
 
These spacecraft will allow NASA to add a seventh crew member to each station mission, effectively doubling the amount of time astronauts will be able to devote to research in space, expanding scientific knowledge and demonstrating new technologies.
 
Astronauts also will lift off again from NASA’s Kennedy Space Center in Florida aboard the Orion spacecraft, launched on the agency’s Space Launch System rocket, to unprecedented missions in lunar orbit.
 
There, the space agency will learn more about conducting complex operations in a deep space environment before moving on to longer duration missions as it progresses on its journey to Mars.
 
To help accomplish this work, NASA will select qualified astronaut candidates from a diverse pool of US citizens with a wide variety of backgrounds, including engineers, scientists and physicians.
 
Astronaut candidates must have a bachelor’s degree from an accredited institution in engineering, biological science, physical science, computer science or mathematics. An advanced degree is desirable.
 
Candidates also must have at least three years of related, progressively responsible professional experience, or at least 1,000 hours of pilot-in-command time in jet aircraft.
 
Astronaut candidates must pass the NASA long-duration astronaut physical.
 
The astronaut candidate application website now is live and accepting submissions till February 18.
