Disc of Destiny:





Disc of Destiny: New optical techniques could preserve data for millennia.

Messages are stored as two types of alterations in the way quartz glass refracts light. The combination of the two allows for data-storage densities as high as 360 terabytes per disc, or more than 7000 times today’s 50-gigabyte double-layer Blu-ray capacity.


Meet the Triquad!








As cool as quadrotors are, in most cases they're simply not as good as helicopters. So researchers came up with a "Y4" configuration that aims to take all the good bits of helicopters and make them as simple as quadrotors. Keep in mind that this is still a quadrotor: it just had things shifted around a little bit.

Flexible Battery Made From Nanotubes







Samsung may be releasing a semi-flexible phone, but researchers have developed a flexible battery made from carbon nanotubes. It's aimed at powering future flexible devices. Using standard electrochemical processes, carbon nanotube-enabled flexible battery can be made to any size.

NEC debutes adorable companion robot







The new robot, Papero Petit, stands 24 centimeters (9.4 inches) tall and weighs 1.3 kg (2.8 lbs)—about half the size of earlier models. It combines multiple sensors (cameras, ultrasonic range finders, temperature sensor, and microphones) to detect people and look in their direction even in complete darkness. The robot can recognize faces and has between 80 to 90 percent success rate at speech recognition.

Keep Walking for Better Health


Just check this out.......

The Organs of your body have their sensory touches at the bottom of your foot, if you massage these points you will find relief from aches and pains as you can see the heart is on the left foot.

Typically they are shown as points and arrows to show which organ it connects to.
It is indeed correct since the nerves connected to these organs terminate here.
This is covered in great details in Acupressure studies or textbooks.

God created our body so well that he thought of even this. He made us walk so that we will always be pressing these pressure points and thus keeping these organs activated at all times.


SMART PEN.




Now, smart pen that vibrates when you make spelling error.

Lernstift is a regular pen with real ink, but inside is a special motion sensor and a small battery-powered Linux computer with a WiFi chip.

Together those parts allow the pen to recognize specific movements, letter shapes and know a wide assortment of words. If it senses bad letter formation or messy handwriting, it will vibrate.

Users can choose between two functions:
Calligraphy Mode - pointing out flaws of form and legibility
or
Orthography Mode - recognizing words and comparing the word to a language database.


Car cum House

Sick Of Paying Rent? Just Build Your Own Tiny Palace, Like These Guys Did...

This house is so small you could practically take it home in your pocket. But its real charm is that its owners are forgoing the "more is more" mentality and living both lightly and beautifully on the planet.

Chris Tack made seven trips to Goodwill to get rid of his stuff, before moving into the 140-square-foot home he and his wife Malissa Tack designed and built. Constructed on a trailer bed and parked in Snohomish, Washington, the house is more than enough space for them, the couple says. And one advantage of a home on wheels, the 29-year-olds say, is that you can always move.


"If bees disappear from face of the earth, we will have only four more years to live"


Bees pollinate about 80% of plants. If plants don't get pollinated, they don't produce seeds and without seeds many plant species will simply die. If this happens, not only will we have no fruit and
vegetables to eat, but many trees will die out and the amount of
oxygen in the world will rapidly decrease, as plants create oxygen.
No Food.
No Oxygen.
No Animals.
No Humans.

Next time you see a bee buzzing around in your house, carefully
help her (yes these hard workers are female) find her way back
outside. She is your life insurance.

Microsoft Wedge Touch Mouse.


Microsoft Wedge Touch Mouse.
The stylish, minimalist design of the Wedge Touch Mouse will allow you to be productive anytime, anywhere in Windows 7 and Windows 8.

THE RAINBOW ROSES!



The Rainbow roses were created by Dutch flower company owner Peter Van De Werken, who produced them by developing a technique for injecting natural pigments into their stems while they are growing to create a striking multicolored petal effects. The dye are produced from natural plant extracts and absorbed by the flowers as they grow. A special process then controls how much color reaches each petal- with spectacular results. By treating the stalk with natural pigments, Van De Werken has manage to make each petal a different color. The pigment is absorbed and travels to the petals where it changes their hue.

AlphaDog - Improved Robotic Pack Mule from Boston Dynamics


Latest Invention: AlphaDog - Improved Robotic Pack Mule from Boston Dynamics

Researchers at Boston Dynamics have come up with an improved version of a robot called AlphaDog that, according to DARPA manager, represents a mix of a pack mule and intelligent animal.

It is worth mentioning that the weight an average soldier is able to carry varies between 60 and 100 pounds. In contrast, the AlphaDog, also called L3 (Legged Squad Support System) is able to carry up to 400 pounds and register a range of up to 20 miles before needing refuel.

Currently the robot is being tested, but researchers have already managed to teach it a couple of new tricks. Thus the machine is able to autonomously follow a human leader, and understand commands from the user that holds a control pad.

The plans for the near future include significant noise reduction and voice command recognition.

Swumanoid Robot..


Latest Invention: Swumanoid - Robot that Could Serve as Lifeguard
A team of researchers at the Tokyo Institute of Technology have recently presented a robot that can replicate the motions of a human swimmer and in the future serve as a lifeguard patrolling the shores.

Together with his teammates, the lead researcher associate professor Motomu Nakashima called their creation Swumanoid. The robot can swim front crawl, reaching a speed of 0.64 meters per second, as well as backstroke and butterfly.

The machine's goal is to estimate water resistance and study how people swim. Information collected during studies could help improve a swimmer's technique.

To be able to build the body, researchers used a 3D scanner on an unknown Olympic athlete. Then they created a plastic model that can be modeled in virtually any size.

Currently researchers are dealing with such major issues as endurance, output and waterproofing of their invention. In the coming weeks, according to the researchers, these problems will be solved.

Japanese Earth Simulator Predicts Seasonal Climate Variations


At JAMSTEC's Application Laboratory, Professor Toshio Yamagata, from the Graduate School of Science at the University of Tokyo, makes use of the Earth Simulator. This is part of a project meant to help forecast climate variations.

It was reported that seasonal prediction information simulated by the Earth Simulator allows specialists to figure out the mechanisms of global climate variations that take place as a result of global warming. At the same time the simulator makes is possible to improve infrastructure in developing countries in a way to prevent disasters.

In addition, the information provided by the Earth Simulator can be used to halt the spread of diseases, carried by vectors such as mosquitoes.

Information on climate variation can also be used in developed countries to predict the supply and demand for energy and food, alterations in prices, revenue from foods and beverages, as well as demand for various consumables.

Professor Yamagata also looks forward to using data offered by the Earth Simulator to provide information services around the world.

Biooctanic - the Huge Biofuel Producing Towers

A somewhat hypothetical idea was proposed by architects from UPI 2M in Croatia. They decided to design buildings that will serve as biofuel production facilities.

The designers called their project "Biooctanic" and it includes a series of towers, each having the shape of a cactus and each producing biofuel crop. These towers will be situated in an urban area near petrol or gas stations.

The main idea of the project is that if fuel producing centers will be constructed at the refill locations, the biofuel facilities can act as air filters (making fresh oxygen in smog-filled cities), plus they will reduce transportation costs.

The futuristic towers will use as feedstocks algae and bamboo, the combination of which, according to UPI 2M's researchers, can generate the maximum amount of biofuels per unit of building surface area. The designers also analyzed the cost of technologies that will be needed for cultivation and processing. In addition, they estimated the growth rate and the annual input-to-yield ratio.

Although initially the project was developed for cities in Croatia, it could be implemented in virtually any location on the globe. The production of biofuel at the place of sale and distribution has several advantages, including lower transportation costs and reduced emissions, informs DesignBoom. In addition, just like vertical farming, the production of urban biofuel does not require arable land.

Living in Space Makes You short, Fat and Bald

Living in Space Makes You short, Fat and Bald
Scientists claim that a long stay in space can leave you bold, short and fat.

They say that living for many years where there's no gravitation has a negative effect on human looks due to the fact that people won't need to move or keep warm.

Astrobiologist Dr Lewis Dartnell says that near zero gravity causes underdevelopment of the bones and muscles.

Besides, living for years in space leaves people with bloated faces and bald, since fluid would pool in the human skull and there would be no necessity for insulation from the cold.

"With no need for hair to insulate the head or eyelashes to flick dust from their eyes, future humans may become completely hairless," said Dr Dartnell, from University College London.


3D Printer to Make Buildings from Moon Dust

A "mad scientist" by the name Enrico Dini has developed a 3D printing machine that can print structures in solid rock. What is the most impressing is that the engineer hopes his invention will help construct buildings on the moon.

The giant device is the world's first printer able to make entire buildings. Currently the engineer uses sand but in the future he hopes his 3D printer is going to make structures from moon dust.

Dini called his device D-Shape. Using hundreds of needles, the printer sprays a thin layer of sand together with magnesium-based glue. It would be interesting to note that the device has a resolution of 25 dots per inch (dpi). The glue is used to bind the sand into a solid rock that raises layer after layer to eventually form a structure, informs Blueprint Magazine.

Currently the engineer is in talks with La Scuola Normale Superiore, Alta Space, and Norman Foster to bring some changes to the 3D printer so the machine could use moon dust to construct buildings.

Virus to kill HIV Virus


An Australian researcher has developed a gene therapy that turns the HIV virus against itself. The inhibitor (a modified protein) has been tested in the lab and the results were quite promising. Such a treatment could give people infected with HIV the possibility of maintaining a healthy immune system, which means they wouldn't develop AIDS. This is a fantastic breakthrough, but there is still more work to be done.

Jugular Venous Pressure Measurement (JVP)


Jugular Venous Pressure Measurement (JVP)

The technique for examination for CVP (central venous pressure)
Patient reclining with head elevated 45 °
Measure elevation of neck veins above the sternal angle (Lewis Method).

Add 5 cm to measurement since right atrium is 5 cm below the sternal angle.

Normal CVP <= 8 cm H2O

Light should be tangential to illuminate highlights and shadows.
Neck should not be sharply flexed.

Using a centimeter ruler, measure the vertical distance between the angle of Louis (manubrio sternal joint) and the highest level of jugular vein pulsation. A straight edge intersecting the ruler at a right angle may be helpful.

If the internal jugular vein is not detectable, use the external jugular vein. The internal jugular vein is the preferred site.

Why color of Water differs from Place to place



The next time you are standing
by a lake, pond or the ocean, ask
yourself why it looks the way it
does. What makes oceans and lakes
look blue or green and sometimes
black? Why do rivers most often
appear brown? When you cup some
of the water in your hand, it's
colorless, but look at the body of
water and it's a color. The most
obvious answer is that it reflects
the sky since you can see reflections
of clouds also. But reflection is only
part of the answer.

It is true that part of the light you
see is a surface reflection of sky
light. The amount of this sort of
reflection, though, depends on a
number of things such as your
viewing angle. On the other hand,
much of the color you see comes
from the water's depths.

White sunlight contains all colors..
Water absorbs some of these colors
more than others. But you need a
lot of water to notice this effect -
which is why water cupped in your
hand has no color at all. In a large
body of water though, the water
molecules quickly absorb red light,
but they don't absorb blue light
nearly
as well. So in this case, more blue
light is transmitted through the
water. It's actually the same
principle behind why the sky is
blue.

The blue effect is often increased
because ocean and lake water
usually contains floating particles
of dirt, and dead and living plants
and animals. They help reflect the
blue light back upward - so that the
lake or ocean looks blue. The blue-
green of tropical waters is due
entirely to absorption of red light
rather then suspension of particles.
It's a different blue than the blue
of the oceans off the northeast
coast, whose blue is caused by
suspended particles and plants.

So now we know why some bodies of
water appear blue, but what about
the other water colors, like gray,
brown and black? Different colors
can be produced by specific things
suspended in the water. Mud acts in
the opposite way from water -- it
reflects red light more than blue. So
muddy water looks brown. Since
rivers are big transporters of mud,
they usually appear brown. Peat
dissolved in water absorbs almost
all the light that touches it - so a
lake full of peat may look black. The
ocean often usually looks gray on a
stormy day. Partly, that's reflected
gray sky - but it's also because
clouds filter out a lot of the sun's
red light before it ever reaches the
water.

Colors of water can be pretty
distinctive. The Black Sea is so
named because of its color, a very
dark almost black color. In this
case, it's the almost constant fog
over the Black Sea that absorbs
incoming light and makes the sea
appear black. It was enough to make
the Turks and many other sailors
want to avoid what they saw as an
evil looking sea!

Human Brain Analysis - Man vs. Woman......A MUST READ!


1. MULTI-TASKING
Women - Multiple process
Womens brains designed to concentrate multiple task at a time.
Women can Watch a TV and Talk over phone and cook.
Men - Single Process
Mens brains designed to concentrate only one work at a time. Men can not watch TV and talk over the phone at the same time. they stop the TV while Talking. They can either watch TV or talk over the phone or cook.

2. LANGUAGE
Women can easily learn many languages. But can not find solutions to problems. Men can not easily learn languages, they can easily solve problems. That's why in average a 3 years old girl has three times higher vocabulary than a 3 yeard old boy.

3. ANALYTICAL SKILLS
Mens brains has a lot of space for handling the analytical process. They can analyze and find the solution for a process and design a map of a building easily. But If a complex map is viewed by women, they can not understand it. Women can not understand the details of a map easily, For them it is just a dump of lines on a paper.

4. CAR DRIVING.
While driving a car, mans analytical spaces are used in his brain. He can drive a car fastly. If he sees an object at long distance, immediately his brain classifies the object (bus or van or car) direction and speed of the object and he drives accordingly. Where woman take a long time to recognize the object direction/ speed. Mans single process mind stops the audio in the car (if any), then concentrates only on driving.

5. LYING
When men lie to women face to face, they get caught easily. Womans super natural brain observes facial expression 70%, body language 20% and words coming from the mouth 10%. Mens brain does not have this. Women easily lie to men face to face.
So guys, do not lie face to face.

6. PROBLEMS SOLVING
If a man have a lot of problems, his brain clearly classifies the problems and puts them in individual rooms in the brain and then finds the solution one by one. You can see many guys looking at the sky for a long time. If a woman has a lot of problems, her brain can not classify the problems. she wants some one to hear that. After telling everything to a person she goes happily to bed. She does not worry about the problems being solved or not.

7. WHAT THEY WANT
Men want status, success, solutions, big process, etc... But Women want relationship, friends, family, etc...

8. UNHAPPINESS
If women are unhappy with their relations, they can not concentrate on their work. If men are unhappy with their work, they can not concentrate on the relations.

9. SPEECH
Women use indirect language in speech. But Men use direct language.


10. HANDLING EMOTION
Women talk a lot without thinking. Men act a lot without thinking.

List of wars with highest cost of causalities/deaths tolls across the world.


List of wars with highest cost of causalities/deaths tolls across the world.

This list of wars by death toll includes deaths that are either directly or indirectly caused by war. These numbers include both the deaths of military personnel which are the direct results of battle or other military wartime actions, as well as the wartime/ war-related deaths of civilians, which are the results of war induced epidemics, diseases, famines, atrocities etc.

Two of the ten most highly estimated death tolls, have been waged in the last century. These are of course the two World Wars. Most of the others involved China or neighboring peoples.
