Ligers are the world's biggest cats, larger than their parents, with the strength of a lion and speed of a tiger combined.

An average male liger stands almost 12ft tall on its hind legs and weighs up to half a ton, twice the weight of a wild lion or tiger.

How did the liger appear?

If the father is a lion and the mother a tiger, the offspring are known as ligers and the pairing results in gigantism.

Strangely, if the pairing is reversed and the mother is a lion, the offspring - known as a tigon - will be small, weighing less than 150 kg.

Ligers (picture left) and tigons (picture right) are not thought to appear in the wild, as the behavior and habitats of lions and tigers make interbreeding unlikely.

In the Thirties in South Africa, the two species were put in the same cage and, to the keepers surprise, they didn't fight. In fact, they made love, and the liger was born.

So popular did they become that zoos in Europe clamored for specimens and so stray dogs on that Continent also came to be frightened away by massive mounds of manure.

Ligers look like both their parents only bigger. Their teeth are whoppers: two inches long.

They may resemble either parent, and range from white to gold to brown, with or without spots and stripes. A male liger may have a mane, but it is usually much smaller than his father's.

As hybrids, ligers have low fertility rates, but some females have produced an offspring by mating with full lions or tigers. Liger males are totally unfertile though.

On a typical day, a liger will devour 9kg of meat, usually beef or chicken, and is capable of eating 45kg at a single sitting. When he is fully grown he is expected to reach 3.5m, and more than 300kg.

Ligers and tigons

Ligers (image 1) are the offspring of a male lion and female tiger. Tigons (image 2) are the offspring of a male tiger and female lion.

While you would think they are similar, in fact the two animals are very different.

While ligers are the mightiest of cats, tigons are in fact smaller than a lion or a tiger.

Tigons are even harder to breed than ligers and there are less tigons in the world. Although tigons are more inclined to dwarfism, it is not always the case.

However, they weigh on average almost 3 times less than a liger.

1. Background music does not improve your ability to concentrate but will help you when you're at the gym. It can affect how you work. A little background noise makes you more creative, a lot hurts creativity.

2. Your favorite song is probably your favorite because you associate it with an emotional event in your life. Both social influences and quality affect which songs you like. You don't like the original version of a song because it's better, you like it because it's the one you heard first. Whether a musician makes eye contact during a concert and what they wear affects whether you like their music.

3. When times are tough people prefer music that's more meaningful. Music can predict the stock market. Popular music has been getting more narcissistic for a while now. All the best songs are about sex anyway.

4. There's a lot of evidence that playing music can make you smarter. Listening to classical music might increase that IQ as well. (And smarter people like classical music.) Music can literally affect the way you see the world and lyrics can influence your behavior. Liberals own a wider variety of music than conservatives.

5. Bar owners get you to drink more by turning the music up. Love songs and romantic music make you spend more in flower shops. Classical, jazz and popular music make you spend more in restaurants.

6. Rockstars do really live fast and die young. It can cost upwards of a million dollars to make a hit song. Music piracy helps big bands and hurts little bands. "Overall, the Beatles' lyrics became darker, more psychologically distant, and less immediate over time."

7. The music you like does say a lot about your personality because different personality types are drawn to different music. Your personality also affects how you use music. You get some of your musical taste from your parents. The music you'll like when you're old is probably what you were exposed to between ages 16 and 21. You can tell how conscientiousness and agreeable a man is by watching him dance- and if he keeps dancing he'll get more creative.

8. Country music can make you want to kill yourself but rock music won't. Classical is the most relaxing. People who like heavy metal don't have issues. Jazz musicians actually "turn off" part of their brain to be more creative. Romantic music does help men pickup women. Music can persuade you to do unethical things. Good music can increase pain tolerance and reduce anxiety. Melodies are more responsible for how music makes us feel than lyrics.

9. People who really like music are more likely to get songs stuck in their head and the best way to deal with an "earworm" is to just accept it. People who are very open to new experience are more likely to get the chills from good music. Yes, you can be addicted to music but Robert Palmer will be disappointed to find out you probably aren't "Addicted to Love."

10. An Italian singer wrote this song with gibberish to sound like English. If you've ever wondered what other people think Americans sound like, this is it.

Schools are moving toward a model of continuous, lifelong learning in order to meet the needs of today's economy.

Corey Brickley

When the giant Indian technology-services firm Infosys announced last November that it would open a design and innovation hub in Providence, the company's president said one of the key reasons he chose Rhode Island was its strong network of higher-education institutions: Brown University, the Rhode Island School of Design, and the Community College of Rhode Island.

In a higher-education system that is often divided between two- and four-year colleges and further segregated between elite and nonelite institutions, it's not often that a community college is mentioned in the same breath as an Ivy League campus. Nor is a two-year college seen as a training ground for jobs in the so-called creative economy, which include industries such as design, fashion, and computer gaming that typically require bachelor's degrees.

But the Community College of Rhode Island, New England's largest two-year college with more than 15,000 students, is working hard to change the tired image of two-year institutions as places for high-school graduates who can't hack it on four-year campuses or for the unemployed trying to figure out what's next. Led by Meghan Hughes, a relatively new president with an academic background in art history, the college is overhauling its approach to workforce development by better aligning programs with the state's economic priorities than is currently the case.

"Like many colleges, we tended to be more reactive and slower to respond to training needs," said Julian Alssid, who started last summer as vice president of workforce development. The college would typically wait for displaced workers to come to the campus to receive retraining instead of intervening before they were laid off. It had advisory groups of employers to provide guidance on certificates and degrees, but they met infrequently, so it would take months or sometimes years to tweak existing programs or start new ones.

Now, the college is in the process of reorganizing its continuing-education division to build ongoing partnerships with companies to keep it current on industry trends and operate training programs responsive to and in sync with the labor market. The alliance with Infosys is a good example of this new strategy as the college works with the company to figure out how the school can help in recruiting and training 500 workers who will make a median salary of $79,000.

The problem with many existing workforce-training programs, Alssid said, is that employers, colleges, and local workforce boards responsible for doling out federal funds "all operate separately, calcified in their own silos." In this new economy, he added, "those worlds will blend together."

The world of work is undergoing a massive shift. Not since the dawn of the Industrial Revolution in the 18th and 19th centuries and the Information Age that followed in the last century has the scale of disruption taking place in the workforce been so evident. An oft-cited 2013 study from the University of Oxford predicted that nearly half of American jobs-including real-estate brokers, insurance underwriters, and loan officers-were at risk of being taken over by computers within the next two decades. Just last fall, the McKinsey Global Institute released a report that estimated a third of American workers may have to change jobs by 2030 because of artificial intelligence.

Previous shifts in how people work have typically been accompanied in the United States by an expansion in the amount of education required by employers to get a good job. In the early 1900s, the "high-school movement" turned secondary schools into a nationwide system for mass education that provided training for life instead of small-scale institutions designed to prepare a select group of students for college. In 1910, just 9 percent of American youths earned a high-school diploma; by 1935, 40 percent did.

This expansion of high schools was the first wave in a century-long broadening of education in the United States in response to the changing needs of the economy. The high-school movement was "truly path breaking," wrote Claudia Goldin, a Harvard University economist, in a paper published by the National Bureau of Economic Research. "No other country underwent the transformation to virtually universal public secondary education" so early and so quickly. "Without the rapid rise of the high school," Goldin argued, "America could not have put the GI Bill of Rights ... into immediate action after 1944 for American youth would not yet have graduated high school."

The second wave in expanding education for a changing workforce occurred in the 1960s with the "college-for-all" movement. In 1965, President Lyndon B. Johnson signed the Higher Education Act, which bolstered federal aid for higher education. Meanwhile, states built community college campuses and widened the mission of state teachers' colleges by adding a bevy of programs in all academic fields. Between 1970 and 2016, enrollment in higher education more than doubled from 8.5 million to 20.5 million students.

Now a third wave in education and training has arrived, argue economists, educators, and workforce-development officials. The level of preparation that worked in the first two waves-adding more time to education early in life-does not seem sufficient in the 21st-century economy. Instead the third wave is likely to be marked by continual training throughout a person's lifetime-to keep current in a career, to learn how to complement rising levels of automation, and to gain skills for new work. Workers will likely consume this lifelong learning in short spurts when they need it, rather than in lengthy blocks of time as they do now when it often takes months or years to complete certificates and degrees.

With this third wave will come a shift in how workers perceive retraining, said Brent Parton, deputy director of the Center on Education and Skills at the think tank New America. "We tend to think of retraining now as something that follows a traumatic event-a job loss, for instance," said Parton, who served as a policy advisor in the U.S. Department of Labor during the Obama administration. "We're entering a stage where retraining will be the day-to-day world that people live in. It will be part of their daily life and a much quieter set of traditions compared with now."

One big worry, however, is that the arrival of lifelong education will only exacerbate the economic divide that already exists in the United States. Education levels in the U.S. are closely tied to income. Simply put: Rich kids are far more likely to graduate from college than are their poor and working-class peers. There's no reason not to believe that trend won't continue in this third wave of lifelong learning. It is likely to help workers who already have high levels of education get the training they need rather than assist underemployed or unemployed workers who need to upskill to keep a job or get a new one.
