Google Map - Street View of Human Body


Google Map helps to search and map the towns,cities,oceans and to the extreme aids in indoor viewing of places too.
Like Google Map,Researchers can soon "street view" the inner workings of the human body.
An international group of researchers have successfully created the most comprehensive map of the human metabolism, called Recon 2, which details how the body’s converts food into energy, and assembles all of the hormones and proteins that contribute to a normal day’s work for cells and tissues.
Genes may form the foundation of the human condition, but it’s their activity, in the shape of the products they make — from enzymes and hormones to nutrients and signalling factors — that dictate how cells interact with each other, and how body systems, such as the way we breakdown food into energy, operate.

“It’s like having the coordinates of all the cars in town, but no street map,” Bernhard Palsson, a professor of bioengineering at the University of California San Diego (UCSD) Jacobs School of Engineering, and one of the authors of the paper said in a statemnt. “Without this tool, we don’t know why peopel are moving the way they are.”
By putting together how genes and their products interact across entire networks, he and his colleagues are confident that Recon 2 could help to expose some of the still mysterious causes of diseases like cancer and diabetes, as well as lead to better treatments.
Recon 2 resembles a “Google map” since it consolidates all the details of human metabolism functions into one interactive tool and allows users to zoom in to view as much detail, at a cellular level, as they want, or to zoom out to get a broader perspective of all the different metabolic reactions that might be involved in a particular function. Such analyses can reveal patterns in function that might not otherwise be obvious to scientists working on more limited projects. In a release describing the scope of the project, University of California San Diego officials wrote:
This is not unlike how you can get a street view of a single house or zoom out to see how the house fits into the whole neighborhood, city, state, country and globe. And just as Google maps brings together a broad set of data – such as images, addresses, streets and traffic flow – into an easily navigated tool, Recon 2 pulls together a vast compendium of data from published literature and existing models of metabolic processes.

what is condensation?


Condensation is the process by which water vapor becomes liquid.It is the opposite of evaporation.

Note
* Water vapor is the water in its gaseous state.
*Evaporation is the process by which water is converted from its liquid form to its vapor form.


A simple experiment to understand the concept of condensation.

1.Take a Thermos Flask(Vacuum Flask) and a Big Ladle.

2.Put the ladle in the cold water.

3.Then remove the lid of the vacuum flask.Fill the flask with hot water and place the ladle over the mouth of the flask.

4.Now you can note the water droplets falling off from the ladle.

5.Water droplets are formed when steam from the the vacuum flask touches the cold surface of the ladle.This is known as Condensation.

6.How rain is formed? When the accumulation of this droplets become plentiful,they fall as rain.

In Simple Words, Condensation occurs when warm air comes into contact with cold surface,which is at a lower temperature.

In other words,Condensation is the formation of liquid drops of water from water vapor. It is the process which creates clouds, and so is necessary for rain and snow formation as well.

Do you Love Popping your Knuckles?



We can't find a person alive , without doing knuckle cracking.Everybody
 loves to hear the sound of knuckle-cracking.

How do your knuckles makes sound?

All the joints in our body is surrounded by a thick, clear liquid called synovial fluid.

When you try to stretch or bend your finger to crack your knuckles, a gas in the synovial fluid escapes and turns into a bubble which then burst and produces the popping sound in your knuckles and other joints like toes,knees,neck etc.

Cracking your joints will stimulates your tendons and relaxes your muscles.

There is a popular belief that knuckles cracking will lead to arthritis.Cracking your knuckles will not hurt your bones or cause arthritis.Too much of knuckle cracking may cause tissue damage in the affected joints.

Once if you crack your joints,you can't do it for another 25-30 minutes until the gas gets reabsorbed into the synovial fluid.

Are Kids' Senses Ready for School?


When setting off for kindergarten or first grade, a child may feel prepared with a backpack loaded with crayons, pencils and paper. But a good start in the classroom depends on more than just school supplies. Healthy hearing, vision, speech and language are key to success at school. If a child has problems in these areas, the sooner they're spotted, the better they can be treated.
Sometimes problems with senses, speech or language can fly under the radar. A child with a lazy eye or a little hearing loss might get along just fine at home or in daycare. But when children get to school, minor difficulties may start to catch up with them. They may have trouble focusing and flourishing in the classroom. NIH-funded scientists are searching for better ways to recognize and treat these types of problems as early as possible.
Senses
Permanent hearing loss used to be caught around age 2. Now newborns are screened for hearing loss before leaving the hospital. When problems are diagnosed, most children are fitted with hearing aids in the first few months of life.
But hearing problems can also arise in older kids. "Some children can be born with normal hearing and develop hearing loss later for various reasons," says Dr. Mary Pat Moeller, who studies childhood deafness and language development at Boys Town National Research Hospital in Nebraska. Head injuries and meningitis are just a few conditions that can lead to later hearing loss.
"We rely on normal hearing to pick up concepts and learn new words," Moeller says. But a noisy classroom can be tough for kids who can't hear well. "Children with undetected hearing loss may look like they have attention deficits. They may miss what they've been told because they're just not hearing clearly," Moeller says.
Screening for hearing loss in school-age kids is a familiar process. Children wear headphones and raise their hands as they hear a series of tones. Some 5% to 10% of school-age children don't pass these tests. Kids with hearing loss can be fitted with hearing aids.
Children learn language by listening to others and engaging in conversations. But kids with hearing loss can miss out on some of this experience. Moeller and her colleagues are studying how children with hearing loss develop language. Early results from this NIH-funded research point to several factors that can help. These include the quality and fit of hearing aids, how often kids get speech and language training and how often parents have conversations with their children.

Genes for face shape identified


Understanding the genes that determine human facial shape could one day provide valuable information about person's appearance using just their DNA.
The discovery of five genes involved in facial form could have applications in forensics, say the authors of a study.
Virtually nothing was known about the genes responsible for facial shape in humans.
The study of almost 10,000 individuals is published in Plos Genetics.
Lead author Manfred Kayser from the Erasmus University Medical Center in Rotterdam, the Netherlands, said: "These are exciting first results that mark the beginning of the genetic understanding of human facial morphology.
"Perhaps some time it will be possible to draw a phantom portrait of a person solely from his or her DNA left behind, which provides interesting applications such as in forensics."
The researchers used magnetic resonance imaging (MRI) of people's heads together with portrait photographs to map facial landmarks, from which facial distances were estimated.
MRI images were used to quantify the metrics of face shape ahead of the genetic study 

They then conducted what is known as a genome-wide association study, which is designed to search for small genetic variations that occur more frequently in people with particular facial types.
Prof Kayser and his colleagues identified five candidate genes associated with different facial shapes - known as PRDM16, PAX3, TP63, C5orf50, and COL17A1.
These associations mean the likelihood of a certain face shape can be estimated, and a full DNA-to-portrait mapping still remains a distant prospect.
But together with recent findings that suggest DNA can also be used to predict hair and eye color and a 2010 study in which age can be inferred from blood, forensics is set to add a suite of powerful new DNA-based tools to its arsenal.

What is an Ultrasound?

Ultrasound is a procedure that uses high-frequency sound waves to view internal organs and produce images of the human body. The human ear cannot hear the sound waves used in an ultrasound.


Ultrasound technology was originally developed as sonar to track submarines during World War I. It was first used medically in the 1950s and is considered very safe.




Ultrasound examination is also called as sonography. The images produced during an ultrasound examination often provide information that's valuable in diagnosing and treating a variety of diseases and conditions.Despite its valuable uses, ultrasound can't provide images of all areas of the body.

Ultrasound examinations are performed only by trained professionals such as sonographers, radiologists and obstetricians.

Ultrasound  is used for many purpose but most commonly during pregnancies it is used  to detect the abnormalities in the fetus and to evaluate a fetus .

On the flip side,it cannot give a definite answer to every problem on every occasion.

What is Temperature?


Temperature is measured using thermometer.It is the measure of how hot or cold things are. 

Temperature is measured in degrees on the Celsius (°C),Fahrenheit and Kelvin scales.

* Ice melts at exactly 0°C.

* A hot bath is about 40°C

* Water boils at exactly 100°C

Interesting Facts 

You can tell the temperature by listening to the chirping of a cricket.

Wonder How ?

Here is the answer.

The frequency of chirping varies according to temperature. To get a rough estimate of the temperature in degrees fahrenheit, count the number of chirps in 15 seconds and then add 37. The number you get will be an approximation of the outside temperature.
