How does the Lotus Flower Clean itself?

How does the Lotus Flower Clean itself?

How will you explain the meaning of purity to someone? Well, many people do it by giving the example of the lotus — it grows in muddy waters but the flower remains spotless. It is not surprising that the lotus has a special or sacred place in world religions like Hinduism and Buddhism. It is a symbol of purity, and many a time gods are shown seated on lotus thrones. Now a group of German Scientists has discovered that the lotus plant is truly spotless....

Dolphin in the Mirror

Dolphin in the Mirror

May 3: Dolphins are much more intelligent than humans previously thought. Scientists have recently discovered that bottle-nosed dolphins can recognise themselves in the mirror – much like you and I can! When you see a zit on your face, what do you do? Go to the mirror time and again, and wonder what it is still doing there. Well, this is exactly what two male bottle-nosed dolphins, Presley and Tab, do as well. So, these lovable aquatic animals are not just seafarers’ friends, but they are also aware of their bodies – almost like humans!...

How Lizards Defy Gravity

How Lizards Defy Gravity

Lizards slithering up walls or dangling precariously from overhead lights are a common sight in tropical countries. These slimy creatures zipping up walls are called geckos. They are the only lizard species that make any sound, other than hissing — in fact they make a loud clicking noise that sounds like “gecko”, hence the name. Recent studies show that the gecko’s ability to cling on to surfaces could well lead to the creation of the world’s first non-sticky, self-cleaning adhesive!...

Jupiter's New Moon

Jupiter's New Moon

Does Jupiter, the largest planet in the solar system, have a 17th moon? Astronomers seem to think it does. Last year, astronomers at the University of Arizona and a Massachusets Observatory discovered what looked like a new moon around Jupiter. They had been scanning the skies for comets and asteroids as part of a spacewatch programme. In fact, when they saw the new moon, they thought it might be a comet or an asteroid. A comet is a small body of ice and dust that orbits the Sun....

The Hottest way to Catch Crooks

The Hottest way to Catch Crooks

All of us know how crooks are caught. We have seen it in film after film: the police inspector matches the fingerprints on the scene of the crime with the suspect’s fingerprints. And the culprit goes to prison. Fingerprinting has remained one of the best ways to catch a person with a criminal record. The technique was foolproof, for no two people have matching fingerprints — even identical twins. Unfortunately, things are not so simple any more....

Planets! Planets! and more Planets!

Planets! Planets! and more Planets!

Astronomers working at Berkeley and Geneva have found nine new planets circling nearby stars. With this discovery, we now know of 50 extra-solar planets, also called exoplanets. That is a big increase from 41 planets last known five years ago. All these individual planets move in an orbit around a star, which is called their parent star. The astronomers estimate that the Beta Pictoris star has a planet ten times the mass of Earth. It orbits at a distance of about 10....

Dinosaur eggs Found in Patagonia

Dinosaur eggs Found in Patagonia

The film Jurassic Park is peanuts compared to this: Last month, Argentine scientists found thousands of dinosaur eggs in hundreds of nests at Patagonia. A report in the journal New Scientist says that it is the biggest nesting site of dinosaurs found thus far. Each nest contained 15 to 30 eggs the size of a grapefruit each. The eggs contained bones of titanosaurs which would have weighed about 15 tonnes when fully grown. Close to 100 million years old dinosaur egg....

Robot That Changes Form

Robot That Changes Form

Did you know that the word robot is derived from the Czech word robota? It means compulsory labour or work. The word robot was first used in a Czech drama in 1921. It described a mechanical device that looked human but lacked emotions. It worked mechanically. Modern-day robots do not necessarily look like humans. But they are programmed to handle tasks that are normally carried out by humans, especially in big factories that manufacture products like cars....

The Scent of an Enemy

The Scent of an Enemy

It seems the fish were always a smart lot. Only, humans took some time to realise the fact. Some years ago, scientists had discovered that they identify family members with their smell. Now, scientists in Glasgow University, have discovered something new, according to a report in the journal ‘New Scientist’. They have discovered that the salmon fish go a step further. They actually keep a nose out for fish that smell like outsiders and not like family....

Scientists Find More on the Eureka Man

Scientists Find More on the Eureka Man

Why do ships float on water when in fact they should sink? Why does paper float on water and a paperweight sink? The answer to these questions was accidentally discovered 2200 years ago by the Greek inventor and mathematician, Archimedes. One day, while getting into his bath he noticed water spilling over the sides. In a flash, Archimedes realised the relation between the water that had fallen out and the weight of his body – in other words he discovered why some objects float and some sink!...
