iPhone was released in the USA on 29 June 2007. At that time, 2 models of the iPhone were released. The difference between the two models was in the internal storage and the price. The 4 GB model was priced at $499 and the 8 GB model was priced at $599. Tens of thousands of people waited days before the launch for the iPhone in front of the AT&T and Apple retail stores for buying the iPhone. Matter of fact, lots of stores reported stock shortage within half an hour of the release.

Scientists can detect whether a gene has been effectively inserted into an animal's DNA by adding some type of clearly recognised marker to it. When testing an anti-FIV gene in 2011, scientists at the Mayo Clinic employed a fluorescent protein from a particular jellyfish. The tests were successful, however the cats did glow in the dark. In fact, these cats' offspring sparkle in the dark! Nonetheless, their accomplishment is only one step toward an ultimate solution for AIDS.

Cheese rolling is one of the oddest sports that takes place every spring in Gloucestershire, in the west of England. An 8-pound round of Double Gloucester cheese is rolled from the top of Cooper Hill, and competitors pursue it down to the bottom. They are intended to catch the cheese, but it is nearly impossible, thus the first person to cross the finish line wins the cheese.

Boys, more than girls, are more likely than girls to learn many lessons through experience rather than being told. This can make parenting them difficult, especially if you don't enjoy taking risks yourself. The most difficult challenge may be keeping them safe, so some risks must be avoided. It can also be difficult to be a support person as a parent when the lessons that boys learn bring hardship and tears.

When people meet for the first time, colour recognition accounts for the vast majority of their first impressions. According to studies, those who consistently wear neutral or black make fewer positive first impressions, whereas those who wear brighter colours are more likely to form friendly bonds. Wearing hints of red (for women) or blue (for men) on a first date may result in stronger feelings and a definite second date, whereas those who wear black to a job interview are more likely to be hired.

It doesn't seem to matter what others say about a new lover—in our eyes, he or she is always ideal. This blindness is essential for us to progress in our relationship. It is frequently required to progress to the "attachment stage," as scientists refer to it so that they can stay in love long enough to produce and raise children; in other words, to populate the globe.

According to the World Health Organization, only Belarus consumes more alcohol than Moldova. With each person consuming an average of 16.8 litres of liquor each year (excluding under 15s). Well that is a lot of booze..

When you burp on Earth, gravity keeps the solids and liquids from the food you just ate at bay, allowing only the gas to leave your mouth. Because the gas cannot separate from the liquids and particles in the absence of gravity, burping effectively becomes vomit.

Recently, SpaceX sent four passengers into Earth orbit aboard the Crew Dragon spaceship. A concept for an aeroplane dubbed Rukma Vimana may be found in the book Vaimanika Shastra. G. R. Josyer disclosed the book in 1952, claiming that it was authored by Pandit Subbaraya Shastry (1866–1940), who dictated it between 1918 and 1923. In 1957, the first spacecraft was launched. Looking at the images above, you can see how similar these designs are. So, how did a Pandit in India envisage the concept of a spaceship 34 years before the first spacecraft launched? Is it just a coincidence?

You may hear people claim to be natural multitaskers, and you've probably even seen it in job descriptions, but humans simply cannot multitask. You can listen to music while working, but your brain can only handle one higher-functioning task at a time. That means you'll either be working and ignoring the music, or you'll be working and ignoring the music. People are incapable of thinking about two things at the same time.

It's extremely unusual, yet it has happened. The event known as "coffin birth" happens when a pregnant woman dies and her kid is born spontaneously owing to gases that build up in the abdominal area, placing pressure on the mother's uterus and driving the baby through the birth pathway. According to Smithsonian, one example of this was discovered in the grave of a mediaeval woman who was buried in Italy in 2010.

Despite having one of Europe's oldest histories, Italy has only been a country since 1861. Italy was a unified entity throughout the Roman era. It was thereafter separated into independent states, which it remained until 1861. Because of this lengthy history of individualism, the country now has such a diverse spectrum of cultural variants.

We can't comprehend the mental anguish you've gone through by reading this far.

Apart from  butter-fingers, crossfire, dustbin, fairy story, slow-coach and whoosh, Charles Dickens is also credited with coining the term "boredom" in the Oxford English Dictionary, which he used in his novel Bleak House (1852-3), but this has since been traced back even further, to 1830.

When it comes to the content of their dreams, researchers discovered some differences between men and women. In several studies, men reported dreaming about weapons significantly more frequently than women, while women dreamed about clothing references more frequently than men. Women have slightly longer dreams with more characters than men. When it comes to the characters that appear in dreams, men dream about other men twice as often as women, while women dream about both sexes equally.

Do you consider all of your decisions, weighing all of your options and calculating the impact of each outcome? You may believe you are, but you are incorrect. The majority of your decisions are made subconsciously because your conscious mind would be overwhelmed with information and you would likely become mentally frozen. This is because your brain receives over 11 million bits of information every second, and there simply isn't enough "brainpower" to process it all consciously.

For millions of people, the coffee break is an important but often overlooked part of their day. The town of Stoughton, Wisconsin, hosts an annual Coffee Break Festival to pause and honour the break. There will be coffee tastings, "brew-offs," and bean-spitting contests at the event. What makes Stoughton unique? According to city officials, the coffee break "was born" in the city in the late 1800s, when women working at the local Gunderson Tobacco Warehouse started the ritual of pausing during the workday to brew some coffee and chat.

Fetuses with short protuberances have been observed as early as 16 weeks of gestation. While there haven't been enough studies to determine why this happens, some point to the age-old "use it or lose it" theory—the Los Angeles Times reported that periodic movements are required to keep the penile tissue oxygenated and healthy.

Why doesn't your stomach digest itself if it has so many enzymes and acids that it can digest a piece of meat? It turns out that it sort of does. The cells that line your stomach proliferate fast in order to replace the cells that are killed in the course of their everyday tasks. Every three days, we develop a new gut lining.

Asakusa is a must-see, with its charming streets (and even the metro station) adorned with these beautiful paintings depicting Japanese history. The thick but aesthetically unified murals exude a cultural vibe while fulfilling two functions: art and storytelling. In Asakusa, you can also buy unusual foods and souvenirs and watch cooks produce street delicacies via glass windows. Visit the iconic Kaminarimon temple, albeit you may have to compete with other eager tourists!

In terms of the most educated population, Ukraine ranks fourth in the world. 99.4% of Ukrainians aged 15 and up can read and write. 70% of adult Ukrainians have a secondary or higher level of education. Even Ukraine's current heavyweight champions, Vitali and Wladimir, have doctorates.

According to University of California researchers, we spend 30% of our time daydreaming every day. This proportion can go as high as 70% at times (for example, during long travels), but there's nothing wrong with it. According to studies, those who enjoy floating in the clouds are more creative. They're also superior at problem-solving and stress relief.
