A research is carried out at Columbia University showing that human memory is hurt by Internet search. Internet has provided us with great search engines like Google. We look up for movies, songs, multimedia, researches, books, online helping tools, health caring suggestions etc on Internet everyday. However, such searches over Internet is harming effectively human brain. To be more accurate, “Internet has replaced our brain’s ability to remember information”. We remember only tools or websites instead of information itself. 

According to the study, we use our brains as computer uses external hard disks – back up data storage. High percentage of population has access to the Internet shows the high dependency on Internet. Even we people don’t bother to remember because we have an alternate in the form of Internet. Actually, we living with Google brains not with human brains. Even sometimes if we don’t find anything on Internet, we simply ignore its existence. 

The study’s participants went through four tests to conclude such frightening results. Please let us know whether you agree or not? through your comments.

The viral load  monitoring  is so expansive because of resource-poor setting and expansive equipment. The lab of Rustern lsmagilov has designed a cheap Microfluidic Chip. Its capable of monitoring viral load in the blood stream cheaply.

This figure shows slip chip

A standard laboratory tool called PCR is used to measure the concentration of HIV.  The Digital PCR is also in use which is more effective and accurate in counts. Microfluidics is the recent technology for this purpose.  The sample is divided in multitude of tiny wells. Each well contains almost 1 molecule. Molecules are then amplified and then the result would be  either “yes” or “no”.

The microfluidic device shown here

In order to handle the measurement of large dynamic range, as HIV viral load ranges from 50 to a million molecules per ml, divide the sample in to a series of varying sized-well. Then count the molecules at different concentrations.  Now sum the information through all these, it would be more precised than individual information.

As time passes, the liquid drops is smaller due to advances in medicine and food, while the water coming into the bottles is becoming larger, resulting in population increase and is estimated to reach 10,000 million by 2100.

Today I came across a video explaining the last minutes of Steve Jobs Final moments Of Death In His Last Business Meeting After Launching iPhone 4. The video seems real and the reaction of all the fellows in video seems quite convincing. The only question that need an answer about this video is, why this video got more than a week time to get around the World of Web ? Let us know through your comments about how you feel about this Exclusive Footage.

Its been years since WHO and other organizations repeatedly presented their studies about possible threats for cell phone users. Recently World Health Organization has published a list of Top 10 handsets which emit more radiation, the international standards for handsets is below 1.6 watts per kilogram. The list is as below.

1. Motorola Bravo 1.59 W / kg
2. Droid 2: 1.58 W / kg
3. Palm Pixi: 1.56 W / kg
4. Motorola Boost: 1.55 W / kg
5. Blackberry Bold: 1.55 W / kg
6. Motorola i335: 1.55 W / kg HTC Magic: 1.55 W / kg
7. Motorola W385: 1.54 W / kg
8. Motorola Boost i290: 1.54 W / kg (Tie) DEFY Motorola, Motorola Quantico, Motorola Charm: 1.53 W / kg

Beside this top 10 list, the 10 which emit less radiation are

1. Quantum LG: 0.35 W / kg
2. Casio EXILIM: 0.53 W / kg
3. Pantech Breeze II: 0.55 W / kg
4. Sanyo Katana II: 0.55 W / kg
5. Samsung Fascinate: 0.57 W / kg
6. Samsung Mesmerize: 0.57 W / kg
7. Samsung SGH-A197: 0.59 W / kg
8. Samsung Contour: 0.60 W / kg
9. Samsung Gravity T: 0.62 W / kg
10. (Tie) Motorola i890, Samsung SGH-T249: 0.63 W / kg

So be careful when you decide about your next phone. Don’t forget to let us know, through your comments, that where your own mobile/smart phone lies in the lists.

Medical Billing and Coding admits that working with computers has greatly increased productivity, but has done much harm to our health.

So pay close attention to the graphics and try to live your life full!

Of course this also have the medical opinion that the video explains the phenomenon showing some x-rays. Watch it in video below and avoid to try it.

According to ISCD / EMCDDA, a group of scientists who evaluated different drugs including alcohol  according to 9 criteria, the damage caused directly to those who drink alcohol compared to those who use drugs is significantly large.

The results could be seen in the following graphics developed by Graphic.is.

The bottle look awesome with all those features, but iWater is just stupid..
Missing features :

1. no iOS support
2. no USB charger
3. No Wi-Fi
4. No rear or Front Camera

Last but not least you need to keep in mind, it can only be refilled with Apple’s proprietary water-dispensing apparatus — and water bought through that system can’t be used in any other bottle.

Now Google and Microsoft must come up with their Android and Windows Mobile Water

Its start of year 2011. Few things might be new but problems facing this world are same since years. A question worth to ask ourself is “In this new year are we closer to success or at the verge of destruction?” All human beings are linked and  dependent on all the available resources of the world we live in. One of the main issues is the alarming increase in population and National Geographic has created this impressive and informative video depicting perspective to world’s population. It is anticipated that in 2011 world population would exceed seven billion, National Geographic magazine is determined to produce a 7-part series examining some of the core challenges and solutions to the issues humanity is facing today. “7 Billion” is the first step towards this grate cause, the January 2011 cover of magazine is titled “7 Billion,” offering a broad overview of demographic trends that got us to today and will impact us all tomorrow. The first in-depth story will appear in the March issue, focusing on humans’ impact on the planet’s geology. Other stories will follow throughout 2011.
