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.

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?

Start counting those sheep, since sleep is crucial. Many of history's worst tragedies, such as Chernobyl, Three Mile Island, the Challenger explosion, and the Exxon Valdez oil leak, were caused by a lack of sleep.

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.

The Egyptians placed a high value on the afterlife. They thought that by mummifying a deceased person's corpse, their spirit would continue on in the afterlife for all eternity.

According to research, the average attention span has shrunk by 12 minutes in the last decade. Human attention spans are now shorter than those of goldfish. Some research has even found a link between device multitasking — such as scrolling through social media while watching TV — and declining attention spans.

Granted, everyone dislikes certain colours, but is it really possible to be afraid of a specific colour? Apparently, yes. Chromophobia, also known as Chromatophobia, is an irrational fear or aversion to certain colours. Fortunately, chromophobia is an extremely rare diagnosis that is caused by a conditioned response or a previous negative experience.

Danish researchers investigated 387 pairs of twins in their 70s, 80s, and 90s. They discovered that merely glancing at someone’s face may predict whether they would live until old age. If a person appears younger than their actual age, they will live longer than if they appeared older. And scientists have showed that it is pre-programmed at the DNA level. Telomeres, which are key bits of DNA that signal a cell’s reproduction ability, are also connected to how youthful a person seems. People who appear to be younger have shorter telomeres, yet longer life...

Italy was a dictatorship until 1945, while having a royal dynasty until 1946. Following WWII, the country decided to become a republic, and King Umberto II governed briefly from May 9 to June 12, 1946. He spent the rest of his days in exile in Portugal. In Italy, he is regarded as "the May King," a reference to his exceptionally brief rule.

According to World Tourism Organization statistics, Mexico has the greatest number of international tourists in Latin America and is rated #10 in the world. This is unsurprising considering the variety of culture and environment on offer in Mexico. UNESCO has designated 32 places in the nation as World Cultural Heritage sites. Mexico tops the American continent in this area once more, and is ranked sixth overall.

In the winter, street sellers offer ice cream from paper boxes on the street. At -30 degrees Celsius, there's no need for a freezer (-22 degrees Fahrenheit).

A translator rewrote the story in the 1600s. When the prince attempted to follow Cinderella, Aschenputtel (Cinderella) lost her left shoe at the stairwell.

We frequently predict how we will react to a future event, only to find out that we reacted completely differently than we anticipated. We put our faith in the ability of a single event to change everything, but we frequently discover that it has little effect on how we feel.

Everyone has experienced the agony of rejection at some point in their lives, but did you know that rejection causes physical harm as well as emotional pain? Even if you are unable to feel physical pain, scientists have discovered that the reactions and cascading events that occur in the brain after rejection or physical pain are nearly identical. Furthermore, the same natural chemical is released in both cases.

During the Victorian era, there was a significant change in the way people dressed. The Victorian dress reform, also known as the rational dress movement, occurred between the 1860s and 1890s, during the middle and late Victorian eras. Reformers proposed, wore, and even designed clothing that was more practical and comfortable than what was available at the time.

This curiosity has a social explanation rather than a scientific one. For centuries, society and the media have pushed women to hold themselves to a certain standard, whether it's small feet or a perky behind, and the majority of women have chosen stylish presentation over comfort.

People who have a full bladder are more convincing liars. A strong urge to use the restroom causes a person to focus on self-control, making lying more plausible. Furthermore, they attempt to prevent unnecessary movement. That's why scientists conducting a scientific experiment believed liars who needed to go to the bathroom.

Life is a difficult and dirty affair. If you don't want to lose brain cells, you might want to skip this calorie-burning tip. A 45-minute stroll with your dog would be a safer method to burn 150 calories.

In the second millennium BC, ancient Egyptians described hysteria for the first time. The term 'hysteria' was coined by Hippocrates from the Greek adjective hysterikos, which means "from the womb." He blamed hysteria on the womb wandering within the female body, which caused anxiety, tremors, convulsions, paralysis, and a sense of suffocation. Hysteria was first associated with the brain in the 18th century, rather than the uterus. According to Sigmund Freud, it is caused by trauma and can affect both sexes. The DSM did not remove the concept of hysterical neurosis until 1980. Dissociative disorders are now thought to cause hysterical symptoms.

According to research, our brain can only keep 3-4 pieces of information at a time. Furthermore, this data can only be saved for 20-30 seconds. We forget it after this period unless we keep renewing it in our minds over and again. For example, you are driving while chatting on the phone (do not do this!). The person on the other end of the line gives you a number, but you can't write it down, so you memorize it. You repeat the number several times to keep it in your short-term memory until you disconnect and write it down.

Your brain is working on problem solving and learning skills while you sleep. If you're learning a new skill or studying new information, getting enough sleep and having dreams can help you learn faster.

Robin Dunbar, a psychologist and the director of Oxford University's Social and Evolutionary Neuroscience research department, believes that every guy should spend at least two hours a week with 4-5 buddies. They can use this time any way they choose, from sports to going to bars. According to Dunbar, guys with faithful friends are less likely to be sad and have a better immune system.

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.

You may have noticed that women take more risks than men, and there is a scientific reason for this. Women have a larger anterior cingulate cortex than men, which is the part of the brain that weighs options when making a decision. Some argue that this was evolution's way of making women better caregivers and saving the "tribe" when it came to gathering food and establishing social structures.

Speaking of astronauts, their experience has shown that transitioning from weightlessness to gravity can be taxing on the body. Muscles atrophy and bones lose bone mass in the absence of gravity. According to NASA, astronauts in space can lose 1% of their bone mass per month.
