Is Rain is Produced through Bacteria ?

We had still used bacteria’s in foods and making some medicines, but scientists belonging from Sweden have proposed that bacteria excretes certain types of surfactants that may cause the formation of clouds and lead to rain.
Evidence had been found in the Barbara Naziere at the University of Stockholm that some powerful surfactants secreted by some bacteria helps in creation of water droplets.
A study had bee done over clouds above Brazil, Sweden and Finland has shown that they contain tiny amounts of substances same as surfactants secreted by bacteria.
Now it depends upon us that how can we take benefit of these useful bacteria’s.

Beware of Drone Insects as they can See now !!

US military has a fitted mini camera on insects sized aircraft, so they can transmit sound and photographs.
These cameras are very light and fitted on a single micro chip. Known as “Insects drones”, these are very effective and are controlled about a kilometer away with the help of its estimated frequency.
This device was funded by NASA and developed by Caltech’s Jet Propulsion Lab in Pasadena.
This device will help a lot in secret missions of crime investigation, military purposes and for security purposes etc.

Let imagine a fly sitting on your wall and transmitting your videos as well as your voice.

Can We See with the Help of our Tongue?

A new hope for blind peoples, a time will come when their will be no existence of blindness in this world.

“Wicab” is the company, based in Wisconsin, and in United States has developed a device for blind peoples that allow blind persons to partly see with the help of their tongues.

It consists of a small digital video camera that is fixed into the sunglasses worn by the blind person, which transmits digital signals from the camera into a small base unit that converts these signals into electrical pulses.

These pulses when received are then transmitted into a “lollipop” like device which lies on the tongue. Blind person will then feel the tingling sensations through his tongue which allow him to sense his surroundings.

But some kind of training and practice must be required to fin his way through doors, find various switches and other little sensitive objects.

This device will be marked soon but how much will be costly no one knows yet, lets hope for the best.

Devices to Detect Swine Flue & other Diseases !!

Most of the countries are now struggling to build such devices that can detect diseases automatically.

Therefore most of the airports are installing such devices that can detect flue, fever and other diseases to make their air travel safe and to protect others from it.
Some of the airports had already installed infrared cameras to detect their passengers suffering from fever, due to this technology a patient of swine flu was detected in Turkey but this method is still doesn’t match high perfection.

In recent days Japanese Government has started GPS system that will allow mobile phone users to know about any kind of infection they have, this system will automatically detect when a person talk on a cell phone.

Cough detector has also been developed that will distinguished between a people clearing his/her throat from the cough of a sick person.

Can Paper Be Stronger than Iron !!

Now it is going to be almost everything possible what we had thought in past about their impossibility, one can hardly believe that, One day will come when paper become stronger than Iron, but it is true.

At the royal Institute of Technology in Stockholm, researchers prepared a special type of nano paper which strong enough, that is bullet proof.

This paper is made of cellulose fibers that are tightly woven; these fibers are one millionth of a millimeter in thickness. These are so closely and tightly engaged that they produce a tight network of even a strong bullet proof paper.
This type of paper is prepared by digesting wood pulp with enzymes and chopping the fibers in to a strong paper.

God knows better what will be the next in the minds of humans.

Recycling Energy from Roads and Vehicles !!

We haven’t thought that at one time we will also generate electricity from running vehicles.

But now Engineers had developed such a shock absorber that will take advantage of bouncy and unsmooth roads. This observer will convert energy that emerges from road jumps into electricity. This will be sufficient for running the other components of vehicles such as video LCD or to charge the battery.

Recycling Energy from Roads
BMW and Honda are now trying to develop such a devices that will capture the energy from the engine, that exhausts on braking process.
But the most amazing and highly beneficial project that is under process in UK and Israel, is to collect energy from the roads, this energy will comes due the heavy traffic traveling on the road, they will use generators to convert such energy into electricity.

We see thousands of vehicles pass daily on the roads, and if we reach to store that energy that may be used for street lights, road lights and for other purposes also.

It means water is not just a single source of electricity generation, but there are others too but the only thing is to utilize them.

New Hope for Knee Joints Patients !!

Knee joint pain arrives mostly at the age of 40 to 50, this type of pain arrives when cartilages loses its efficiency due to passage of time and wear out. The main purpose of cartilages are to reduce friction between knee joints, we feel pain when this friction increases.

Lots of efforts are done to produces artificial cartilages to replace the natural that wear out, but the effort was still incomplete.

But now a new research had been done at the Weizmann Institute of Space in Israel and developed low friction joints, all this credit goes to Jacob Klein.

These joints are made of polymer with molecular brushes at its surface. The purposes of these brushes are to attract water molecules which provides sheath as they slide over each other, which automatically reduce friction.
