‘Life began before Earth was born’

If genetic complexity progresses at a steady rate, then the social and scientific development of any other alien life form in the Milky Way galaxy would be roughly equivalent to those of humans, the report said.
WASHINGTON: Life existed long before Earth came into being, and may have originated outside
our solar system, scientists claim. Researchers say life first appeared about 10 billion years ago —
long before Earth, which is believed to be 4.5 billion years old.
Geneticists have applied Moore's Law— which states that computers increase exponentially in

Alexei Sharov of the National Institute on Ageing in Baltimore, and
Richard Gordon of the Gulf Specimen Marine Laboratory in Florida , replaced the
transistors with nucleotides — the building blocks of DNA and RNA —
and the circuits with genetic material.

So, which employees are likely to stay on ?
How software helps firms hire workers more efficiently
THE problem with human-resource managers is that they are human. They have biases; they make mistakes. But with better tools, they can make better hiring decisions, say advocates of “big data”. Software that crunches piles of information can spot things that may not be apparent to the naked eye. In the case of hiring American workers who toil by the hour, number-crunching has uncovered some surprising correlations.
For instance, people who fill out online job applications using browsers that did not come with the computer (such as Microsoft’s Internet Explorer on a Windows PC) but had to be deliberately installed (like Firefox or Google’s Chrome) perform better and change jobs less often.
It could just be coincidence, but some analysts think that people who bother to install a new browser may be the sort who take the time to reach informed decisions. Such people should be better employees. Evolv, a company that monitors recruitment and workplace data, pored over nearly 3m data points from more than 30,000 employees to find this nugget.
Some 60% of American workers earn hourly wages. Of these, about half change jobs each year. So firms that employ lots of unskilled workers, such as supermarkets and fast-food chains, have to vet heaps—sometimes millions—of applications every year. Making the process more efficient could yield big payoffs.
Evolv mines mountains of data. If a client operates call centres, for example, Evolv keeps daily tabs on such things as how long each employee takes to answer a customer’s query. It then relates actual performance to traits that were visible during recruitment.
Some insights are counter-intuitive. For instance, firms routinely cull job candidates with a criminal record. Yet the data suggest that for certain jobs there is no correlation with work performance. Indeed, for customer-support calls, people with a criminal background actually perform a bit better. Likewise, many HR departments automatically eliminate candidates who have hopped from job to job. But a recent analysis of 100,000 call-centre workers showed that those who had job-hopped in the past were no more likely to quit quickly than those who had not.
Working with Xerox, a maker of printers, Evolv found that one of the best predictors that a customer-service employee will stick with a job is that he lives nearby and can get to work easily. These and other findings helped Xerox cut attrition by a fifth in a pilot programme that has since been extended. It also found that workers who had joined one or two social networks tended to stay in a job for longer. Those who belonged to four or more social networks did not.
There is no point asking jobseekers if they are honest. But surveys can measure honesty indirectly, by asking questions like “How good at computers are you?” and later: “What does control-V do on a word-processing programme?” A study of 20,000 workers showed that more honest people tend to perform better and stay at the job longer. For some reason, however, they make less effective salespeople.
Algorithms and big data are powerful tools. Wisely used, they can help match the right people with the right jobs. But they must be designed and used by humans, so they can go horribly wrong. Peter Cappelli of the University of Pennsylvania’s Wharton School of Business recalls a case where the software rejected every one of many good applicants for a job because the firm in question had specified that they must have held a particular job title—one that existed at no other company.

From A Sleepy Koli fishing hamlet to the financial capital of India, Mumbai has come a long way. The Portugese who were its earlier occupants gave it its name – ‘Bom Bai’ or ‘The Good Bay’. Initially an archipelago of 7 islands, this port city rose to prominence after the British East India Company deemed it fit for trading and shifted base from Surat. After a series of reclamations and massive construction efforts, Bombay became what is it today – A mega metropolis. Join us in capturing this iconic journey, through seamless images of the past & the present.
The Reclamation
The Archipelago and Its reclamation: The 7 islands of Colaba, Mazagaon, Old Woman’s Island, Wadala, Mahim, Parel, and Matunga-Sion, underwent a series of reclamations, forming the island city of Mumbai that we see today. Full story here.
Gateway of India
The former pier of Apollo Bander, now replaced by the ever popular Gateway of India, a 26m high archway built to commemorate the arrival of King George V and Queen Mary.
Churchgate Railway station
Bombay was a walled city and Churchgate, now called Veer Nariman Street was one of of three wall gates. It is now home to a new and revamped Churchgate railway station.
Victoria Terminus
Where gothic meets mughal. This lovely railway terminus building Victoria Terminus, now called the Chatrapati Shivaji Terminus, was built in 1887 and is the busiest railway station in India.
Asiatic Town Hall
Iconic. Mammoth. Ancient. One of the oldest public universities in Maharashtra, the University of Mumbai is a landmark structure and is home to the famous Rajabai Tower.
Bhendi Bazaar
The market with the curious etymology. This area was north of Crawford Market and the British referred to it as “Behind the Bazaar”. The natives picked this up as “Bhendi Bazaar” and the named stayed since.
Crawford Market
One of South Mumbai’s most famous & busiest markets where even dogs, cats & endangered species are sold. The architecture is predominantly a blend of Norman & Flemish styles.

Colaba Causeway
A land link between Colaba & Old Woman’s Island, this commercial stretch of road was the first to host horse-drawn tram cars.
Colaba Sea Face
All roads lead to the sea. Leading away from the bustling causeway are tiny perpendicular roads which lead to the serene Colaba seafront.
