How Many Twitter Users Are There 2012

Disclaimer: Because the company isn’t exactly forthcoming with registration data, calculating Twitter’s userbase is as much guesswork as it is science, so take this analysis with the usual hefty pinch. That as it is, there is some history here, so bear that in mind too.

As you may have seen, Facebook has been tipped to reach one billion active users in August of this year. That’s an absolutely amazing number – approximately 14 percent of the world’s population. What’s even more impressive is these are active users, Facebook’s definition of which is people who log in at least once a month. Which doesn’t seem particularly active, to be honest, but this has essentially become the industry standard now.

So how does Twitter compare?

Officially, Twitter has 100 million active users – again, members who log in at least once a month. Which makes the platform about an eighth of the size of Facebook. This was back in September – obviously, Twitter has been growing since then. There’s certainly no reason to assume that the membership is shrinking or even flatlining.

But what about total users?

In April of last year, Katie Stanton, Twitter’s vice president of international strategy, announced that the platform had 200 million registered accounts. In May, independent Twitter account tracker Twopcharts pegged the total registered accounts number at 300 million. In August, this figure had risen to 362 million, and it passed 400 million a couple of months later. Twitter also confirmed that they were receiving 400 million uniques per month in September.

At the time of writing, Twopchart’s number is now up to 462 million and change – which is some acceleration, as it means 100 million new profiles have been registered in less than five months. And Twopcharts is predicting that Twitter will reach 500 million registered profiles in 44 days and 10 hours, which means that Twitter should hit that milestone on Sunday, February 26, 2012.

Or, approximately, and given how everything seems to be speeding up, sometime before March.

Now, again, this isn’t hard and fast science. And remember that this is total registrations on Twitter, which includes all the abandoned and suspended accounts, plus worthless fodder such as spammers, bots and Justin Bieber fans. As an overall number, it’s indicative only of how many people have signed up for Twitter. But it still has some value.

For example, it allows us to make an approximation on how many total active users Twitter has now, given what we know about the relationship between these numbers in September. In that month, Twitter had 100 million active users, and around 362 million registered profiles. So, about 28 percent of Twitter’s registered members were active. This means that, all things being equal, Twitter now has around 127 million active users (27.6 percent of 462 million), and in March this number should have risen to 138 million.

Remember: an active user is someone who logs in to Twitter at least once per month. Nothing more, nothing less.

And before this sounds too impressive, it’s worth noting that back in September I estimated that Facebook, which had 750 million active users at the time, likely boasted 1.875 billion total registered users. All things being equal, that number should be up to two billion on Facebook by now, and is on course to reach 2.5 billion by August. Or, if you prefer to look at it another way, about 37 percent of the world’s population. Which, however you feel about Facebook, is mindblowing.

Still, Twitter is going places, and by my calculations should have around 900 million registered profiles by the end of 2012, and 250 million active users. Sure, it’s long way short of Mark Zuckerberg’s baby, but it might just be enough to change the world.

How Many Stomachs Does a Cow Have

Cattle have one stomach with four compartments. They are the rumen, reticulum, omasum, and abomasum, with the rumen being the largest compartment. The reticulum, the smallest compartment, is known as the “honeycomb”. Cattle sometimes consume metal objects which are deposited in the reticulum and irritation from the metal objects causes hardware disease. The omasum’s main function is to absorb water and nutrients from the digestible feed. The omasum is known as the “many plies”. The abomasum is like the human stomach; this is why it is known as the “true stomach”.

Dairy farming and the milking of cattle – once performed largely by hand, but now usually replaced by machine – exploits the cow’s ruminant biology.Cattle are ruminants, meaning that they have a digestive system that allows use of otherwise indigestible foods by regurgitating and rechewing them as “cud”. The cud is then reswallowed and further digested by specialised microorganisms in the rumen. These microbes are primarily responsible for decomposing cellulose and other carbohydrates into volatile fatty acids that cattle use as their primary metabolic fuel. The microbes inside the rumen are also able to synthesize amino acids from non-protein nitrogenous sources, such as urea and ammonia. As these microbes reproduce in the rumen, older generations die and their carcasses continue on through the digestive tract. These carcasses are then partially digested by the cattle, allowing them to gain a high quality protein source. These features allow cattle to thrive on grasses and other vegetation.

The gestation period for a cow is nine months. A newborn calf weighs 25 to 45 kilograms (55 to 99 lb). The world record for the heaviest bull was 1,740 kilograms (3,840 lb), a Chianina named Donetto, when he was exhibited at the Arezzo show in 1955. The heaviest steer was eight year old ‘Old Ben’, a Shorthorn/Hereford cross weighing in at 2,140 kilograms (4,720 lb) in 1910. Steers are generally killed before reaching 750 kilograms (1,650 lb). Breeding stock usually live to about 15 years (occasionally as much as 25 years). The oldest recorded cow, Big Bertha, died at the age of 48 in 1993.

A common misconception about cattle (particularly bulls) is that they are enraged by the color red (something provocative is often said to be “like a red flag to a bull”). This is incorrect, as cattle are red-green color-blind. The myth arose from the use of red capes in the sport of bullfighting; in fact, two different capes are used. The capote is a large, flowing cape that is magenta and yellow. The more famous muleta is the smaller, red cape, used exclusively for the final, fatal segment of the fight. It is not the color of the cape that angers the bull, but rather the movement of the fabric that irritates the bull and incites it to charge.

Having two kinds of color receptors in the cone cells in their retinas, cattle are dichromatic, as are most other non-primate land mammals.

A cow’s udder contains 2 pairs of mammary glands.

How Many Genes Are There in Human Body

The Human Genome Project (HGP) is an international scientific research project with a primary goal of determining the sequence of chemical base pairs which make up DNA, and of identifying and mapping the approximately 20,000–25,000 genes of the human genome from both a physical and functional standpoint.

The project began in October 1990 and was initially headed by Ari Patrinos, head of the Office of Biological and Environmental Research in the U.S. Department of Energy’s Office of Science. Francis Collins directed the National Institutes of Health National Human Genome Research Institute efforts. A working draft of the genome was announced in 2000 and a complete one in 2003, with further, more detailed analysis still being published. A parallel project was conducted outside of government by the Celera Corporation, which was formally launched in 1998. Most of the government-sponsored sequencing was performed in universities and research centres from the United States, the United Kingdom, Japan, France, Germany. Researchers continue to identify protein-coding genes and their functions; the objective is to find disease-causing genes and possibly use the information to develop more specific treatments. It also may be possible to locate patterns in gene expression, which could help physicians gleen insight into the body’s emergent properties.

While the objective of the Human Genome Project is to understand the genetic makeup of the human species, the project has also focused on several other nonhuman organisms such as E. coli, the fruit fly, and the laboratory mouse. It remains one of the largest single investigative projects in modern science.

The Human Genome Project originally aimed to map the nucleotides contained in a human haploid reference genome (more than three billion). Several groups have announced efforts to extend this to diploid human genomes including the International HapMap Project, Applied Biosystems, Perlegen, Illumina, J. Craig Venter Institute, Personal Genome Project, and Roche-454.

The “genome” of any given individual (except for identical twins and cloned organisms) is unique; mapping “the human genome” involves sequencing multiple variations of each gene. The project did not study the entire DNA found in human cells; some heterochromatic areas (about 8% of the total genome) remain un-sequenced.

Project goals were to

  • identify all the approximately 20,000-25,000 genes in human DNA,
  • determine the sequences of the 3 billion chemical base pairs that make up human DNA,
  • store this information in databases,
  • improve tools for data analysis,
  • transfer related technologies to the private sector, and
  • address the ethical, legal, and social issues (ELSI) that may arise from the project.

How Many Bones Are There in the Human Body

Bones are an important part of the . They give support, shape and structure to the body and perform special functions to allow movement. At birth, the body of a child has about 350 bones. As the body grows and reaches adulthood, a number of bones fuse together giving 206 bones in the adult human body.



An infant may have about 300 to 350 bones in the body but as the body develops, a number of bones fuse together leaving only 206 important bones in the adult body. Each bone performs a special role in the body and supports the movement and functions of the body parts.

The distribution of the 206 bones in the body is as follows:

• 28 bones in the skull (facial bones, ear bones and cranium)

• The horseshoe shaped hyoid bone for the neck

• 26 bones in the vertebraes (neck, thorax, sacrum, etc)

• More than 24 bones comprising of the ribs and the shoulder girdle including sternum and breastbone.

• Single pelvic girdle

• 30 bones in the arms and legs

• A few partial bones about 8 to 18 that help in making and moving the joints.

The shortest bone in the body is the stirrup, which is present in the ear. It is not more than an inch long but is important in carrying the sound from the eardrums to the inner ear. The largest bone is known as the femur, which extends from the hip to the knee. The length of the femur entirely depends on the height of the individual. The maximum number of bones is found in the arms and legs.

Human body is full of surprises. Some bones are fused together while others work independently. Some help in movement while other gives the structure. Each part is essential for the overall growth, development, and efficient function of the individual.

The axial skeleton is the head and the trunk, or anything other than the appendages. There are about 80 bones in the axial skeleton.
There are 22 bones in the skull: eight cranial bones and 14 facial bones. The cranial bones are the frontal, parietal (two), occipital, temporal (two), sphenoid and ethmoid.

The facial bones are maxilla (two), palatine (two), zygomatic (two), lacrimal (two), nasal (two), vomer, inferior nasal conchae (two) and mandible.

The inner ears contribute six bones, or three each. These are called the malleus, incus and stapes–or, in English, hammer, anvil and stirrup.

Underneath the tongue is the hyoid bone. It is often seen damaged in crime scenes when the victim died of strangulation.

The vertebral column and thoracic cage protect the heart, lungs and spinal cord. The vertebral column has 26 bones: seven cervical vertebrae, 12 thoracic vertebrae and five lumbar vertebrae. These are referred to by their numbers: C5, T8, L2, and so on. Below the lumbar vertebrae are the sacrum and coccyx, which are fused bones, but each counts as one.

The thoracic cage has 25 bones: 24 ribs and the sternum. Ribs 8 to 12 are called false ribs. This is because ribs 8 to 10 attach to the cartilage of rib 7, and ribs 11 and 12 are buried in the muscle, and are also called floating ribs.

Pectoral Girdle and Arm
The pectoral girdle consists of two scapulas (shoulder blades) and two clavicles (collar bones). The rest of the upper limb consists of 30 bones each, for a total of 60. Each appendage has the humerus, radius, ulna, eight carpal (wrist) bones, five metacarpals leading to the fingers, and 14 phalanges, or finger joints. Each finger has three phalanges, except for the thumb, which has two.

Pelvic Girdle/Lower Limb
The pelvic girdle is made up of the two os coxae, or hip bones. Each lower limb has 30 bones: the femur, patella, tibia, fibula, seven tarsals (ankle bones, including the heel bone, the calcaneus), five metatarsals and 14 phalanges. As in the hand, the great toe has two phalanges while the other digits have three.

Sesamoid Bones
Sesamoid bones often throw off the count of a person’s individual bones, because they can appear anywhere. These smooth, round bones often form in the knuckles of the hand. The largest and most well-known of these is the patella, or kneecap, which is formed inside the quadriceps femoris tendon.

Another type of “extra” bone is a sutural bone, which forms between the jagged sutures, or seams, of the cranial bones in the skull. There are also called wormian bones, after Danish physician Ole Worm.
