India to launch sixth navigation satellite on Thursday
Chennai : India is slated to put into orbit its sixth navigation satellite on Thursday evening, the Indian Space Research Organisation (ISRO) announced here on Monday.
 
The 1,425-kg IRNSS-1F - Indian Regional Navigation Satellite System-1F - would hurtle into space on board its Polar Satellite Launch Vehicle (PSLV) on March 10, the ISRO said. 
 
The rocket will blast off around 4 p.m. from the spaceport at Sriharikota in Andhra Pradesh, about 80 km from here.
 
This will be already the second rocket launch for India in 2016. The first one was on January 20 when a PSLV rocket put into orbit the IRNSS-1E satellite in text-book style.
 
Till date India has launched five regional navigational satellites (IRNSS-1A, 1B, 1C, ID and 1E) as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500 km.
 
Though the full system comprises nine satellites -- seven in orbit and two on the ground as stand-by -- the navigation services could be made operational with four satellites, ISRO officials had said earlier.
 
Each satellite costs about Rs.150 crore and the PSLV-XL version rocket costs about Rs.130 crore. The seven rockets would entail an outlay of about Rs.910 crore.
 
The entire IRNSS constellation of seven satellites is planned to be completed in 2016 itself.
 
The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014, the fourth in March 2015, and the fifth in January this year.
 
The seventh satellite-IRNSS-1G- is expected to be launched in the second half of 2016.
 
Once the regional navigation system is in place, India need not be dependent on other platforms.

E-mail inventor Ray Tomlinson dies at 74
New York : Internet pioneer Ray Tomlinson, who is credited with the invention of e-mail, has died at the age of 74, media reports said.
 
According to reports, Tomlinson died of an apparent heart attack late on Saturday.
 
The US computer programmer came up with the idea of electronic messages that could be sent from one network to another in 1971, BBC reported.
 
His invention included the ground-breaking use of the "@" symbol in e-mail addresses, which is now standard.
 
He sent what is now regarded as the first e-mail while working in Boston as an engineer for research company Bolt, Beranek and Newman.
 
The firm played a big role in developing an early version of the internet, known as Arpanet.
 
However, Tomlinson later said he could not remember what was in that first test message, describing it as "completely forgettable".
 
A BBC report said his work was recognised by his peers in 2012, when he was inducted into the Internet Hall of Fame.

What makes humans imagine?
New York : Scientists believe that humans possess the unique ability to imagine a never-before-seen object or concept, but there is little that we know about the neurological mechanism behind it.
 
A new experiment proposed by Andrey Vyshedskiy from Boston University may provide new insights into this mechanism by utilising currently available methods for isolating so-called "object neurons" in the human brain. 
 
According to Vyshedskiy, the imagination process can be called "mental synthesis" as it involves mentally combining familiar images, scenes or concepts. 
 
The experiment he suggested involves isolating any two object neurons and monitoring their neuronal activity when these two objects are imagined together for the very first time.
 
If two object neurons that fire only when a particular object is imagined can be identified, then the current experiment would seek to measure the firing activity when these two objects are imagined together. For example, an apple on top of a dolphin.
 
According to the research idea published in the Research Idea and Outcomes Journal, the subject's brain will trigger an increased firing rate in both object neurons and, more importantly, a synchronisation of their activities would occur. 
 
"Since researchers can often identify several object-selective neurons within a single patient, multiple novel pairings of objects can be studied," Andrey Vyshedskiy said. 
 
"Furthermore, morphing of more than two objects into one mental frame can also be investigated," he added.
