A Brief History of Pregnancy Tests

Representatives of Spain and the United States signed a peace treaty in Paris on December 10, 1898, which established the independence of Cuba, ceded Puerto Rico and Guam to the United States, and allowed the victorious power to purchase the Philippines Islands from Spain for $20 million.

When did Cuba gain its independence from Spain?

Cuba had been a colony from 1492 until 1898 when the United States took over the territory in the Spanish–American War.

The kind of music you listen to can change the way you see the world.Music is not only able to affect your mood. Listening to particularly happy or sad music can even change how we perceive the world, according to researchers from the University of Groningen.Music and mood are closely interrelated.

Music and Perception

A study by researcher Jacob Jolij and student Maaike Meurs of the Psychology Department of the University of Groningen showed that music has an even more dramatic effect on perception: even if there is nothing to see, people sometimes still see happy faces when they are listening to happy music and sad faces when they are listening to sad music.

It was first sighted on January 26, 2004. It became the fastest-spreading e-mail worm ever (as of January 2004), exceeding previous records set by the Sobig worm and ILOVEYOU, a record which as of 2019 has yet to be surpassed.MyDoom is the most devastating computer virus to date, which caused more than $38 billion in damage.

Mydoom is a computer worm affecting Microsoft Windows

Mydoom appears to have been commissioned by e-mail spammers to send junk e-mail through infected computers. The worm contains the text message "andy; I'm just doing my job, nothing personal, sorry," leading many to believe that the worm's creator was paid.Early on, several security firms expressed their belief that the worm originated from a programmer in Russia. The actual author of the worm is unknown.

The Worm Text Message

Initial analysis of Mydoom suggested that it was a variant of the Mimail worm, hence the alternate name Mimail.R, prompting speculation that the same people were responsible for both worms. Later analyses were less conclusive as to the link between the two worms.

What Suggested The Initial Analysis

Mydoom was named by Craig Schmugar, an employee of computer security firm McAfee and one of the earliest discoverers of the worm. Schmugar chose the name after noticing the text "mydom" within a line of the program's code. He noted: "It was evident early on that this would be very big. I thought having 'doom' in the name would be appropriate."

When you do yoga, your brain cells develop new connections, and changes occur in brain struc­ture as well as function, resulting in improved cog­nitive skills, such as learning and memory. Yoga strengthens parts of the brain that play a key role in:<ul><li>Memory, </li><li>Attention, </li><li>Awareness, </li><li>Thought, </li><li>And language. </li></ul>

A sharper brain

All exercise can boost your mood by lowering levels of stress hormones, increasing the production of feel-good chemicals known as endorphins, and bringing more oxygenated blood to your brain. But yoga may have additional ben­efits: It can affect mood by elevating levels of a brain chemical called gamma-aminobutyric acid (GABA), which is associated with better mood and decreased anxiety.Meditation also reduces activity in the limbic system—the part of the brain dedicated to emotions.

Improved mood

Yoga can boost your cognitive function and lowers stress.

Fake engine noise has become one of the auto industry's dirty little secrets, with automakers turning to a sound-boosting bag of tricks.Without them, today's more fuel-efficient engines would sound far quieter and, automakers worry, seemingly less powerful, potentially pushing buyers away.

Engine Noise

A lot of new cars fake engine noise through speakers. They are quite silent otherwise.

The engine growl in some best-selling cars and trucks is actually a finely tuned bit of lip-syncing, boosted through special pipes or digitally faked…

Top 10 Hottest Peppers

The Scoville Scale is a measurement of the heat and pungency of chili peppers where each pepper is recorded in Scoville Heat Units (or famously known as SHUs). The scale is named after its creator, Wilbur Scoville, who created the Scoville Organoleptic Test in 1972.

What is the Scoville Scale?

Scoville heat units are a measurement of sugar and water. <ul><li>The test measures chili heat by figuring out how much sugar-water needs to be diluted into a chili pepper to get to where you no longer feel the heat at all. </li><li>What creates that burning sensation on our tongues and makes us sweat is the capsaicin. </li></ul>You should know that heat scales are purely subjective. Even with a scientific test using Scoville Heat Units, the hotness of peppers can vary in the same variety from plant to plant, and even on the same plant!

It wouldn't fly now, but back in 1975, it was a whole different story because a cat named F.D.C. Willard was the co-author of a peer-reviewed physics paper called "Two-, Three-, and Four-Atom Exchange Effects in bcc 3He."Published in the journal Physical Review Letters, the paper describes the results of an experiment exploring the behavior of the helium-3 isotope at various temperatures.

In 1975, a Cat Co-Authored a Peer-Reviewed Physics Paper 

In 1975, a physicist made his cat the co-author of his scientific paper to avoid replacing "we" with "I" throughout his paper.
