Worm Story

with one comment

Did anyone ever know that the earthworm can have sixteen (16, XVI) hearts?

Did anyone know eating eating earthworms can reduce cholesterol?

Did anyone know that earthworms hatch from cocoons smaller than a grain of rice?

Does the word “Worm Grunting” bring weird images to your mind?

Read about the king and queen of worms here.

So how many cells does it take to screw a light bulb?

One, it seems.

Monkeys taught to play a computer game were able to overcome wrist paralysis with an experimental device that might lead to new treatments for patients with stroke and spinal cord injury.

Remarkably, the monkeys regained use of paralyzed muscles by learning to control the activity of just a single brain cell.

Alive with the Sound of Music

leave a comment »

Vanderbilt University psychologists have found that professionally trained musicians more effectively use a creative technique called divergent thinking, and also use both the left and the right sides of their frontal cortex more heavily than the average person.

Doubts:

1. Does this only include classical music or what-is-more-recently-perceived-as-music such as rap and belch music?

2.  Does this include only instrumental experts or bathroom singers too?

3. Elevated IQ score?  Sounds far fetched to me, but heck, I am not the expert.

Slimy Propulsion

leave a comment »

First the gecko.  Now the snail.

`A UC San Diego engineer has revealed a new mode of propulsion based on how water snails create ripples of slime to crawl upside down beneath the surface. […]

Some freshwater and marine snails crawl by “hanging” from the water surface while secreting a trail of mucus. The snail’s foot wrinkles into little rippling waves, which produces corresponding waves in the mucus layer that it secretes between the foot and the air. […]

Anette Hosoi of the Massachusetts Institute of Technology, has already imitated the adhesive/ lubricating propulsive method of land snails to drive a robotic device.

The Contraceptive Song

leave a comment »

And you thought testing various secretions of the body and measuring temperature at various times of the month can tell you the “safe” period for that date with hot dude?

Here is an alternative.

A woman raises the pitch of her voice during her most fertile period of the month in an unconscious boost to her femininity, according to a US study. […]

An analysis of the recordings revealed the closer a woman was to ovulation the more she raised her pitch.

The increase in tone was only slight – it wasn’t Minnie Mouse on helium – but the peaks were enough to be picked up by the voice decoder and presumably by the male ear, as well.

Aha !

Show Me the Meaning of Being Lonely

Show me the meaning of being lonely
Is this the feeling I need to walk with
Tell me why I can’t be there where you are

Simply because it is inhabitable, baby.

The first ecosystem ever found having only a single biological species has been discovered 2.8 kilometers (1.74 miles) beneath the surface of the earth in the Mponeng gold mine near Johannesburg, South Africa. There the rod-shaped bacterium Desulforudis audaxviator exists in complete isolation, total darkness, a lack of oxygen, and 60-degree-Celsius heat (140 degrees Fahrenheit).

D. audaxviator survives in a habitat where it gets its energy not from the sun but from hydrogen and sulfate produced by the radioactive decay of uranium.

From Waste to Use

leave a comment »

Grignard is apparently not the only reaction to convert carbon dioxide to carboxyllic acids any more.

The team [Zhaomin Hou, of RIKEN‘s Advanced Science Institute]was also able to study exactly how the catalyst works, by isolating key molecules at various intermediate stages of the reaction. They found that the active copper catalyst first displaces the boron group from the starting molecule, forming a new copper–carbon bond. Carbon dioxide then inserts itself into this bond before the copper catalyst is finally removed, leaving behind a carboxylic acid (-CO2H) group.
