[h=3]Poor sleep may affect brain function as you age[/h]There is an association between both quality and duration of sleep and brain function which changes with age, the findings showed. In adults aged between 50 and 64 years of age, short sleep (less than 6 hours per night) and long sleep (more than 8 hours per night) were associated with lower brain…

[h=1]180. Enigma of an Eel[/h]
The Electric Eels, capable of sending out electrical discharges as high as 650 Volts, have fascinated humans for ages! The electric eel or “The Electrophorus Electricus” is not an eel at all! It is a rare species of the knife fish, with ability to produce stunning electrical impulses.

The electric eels live in the muddy bottom of calm water bodies. They live in swamps, creeks, South American rivers and oceans too. Young electric eels feed on invertebrates, eggs and embryos. Adult electric eels feed on fish and small mammals.

The electric eel has a long square body. Its head looks flattened and its square mouth is placed right at the tip of its snout. It had a dark, greenish grey body and a yellowish belly. It has no scales but its fins run down right to the tip of its tail.

Electric eel can grow to a length of 2.5 meters and weigh 20 Kilo Grams. It has an exceptionally good hearing ability. Though a fish, it takes in 80% of the oxygen it needs directly from the air. It has respiratory organs in its oral cavity. It surfaces at the intervals of ten minutes, to gulp in as much air a possible.

Electric eel has a “Power House” in its body, which takes up four fifths of it long body. All its vital organs are placed in the front one fifth of its body. The Power House of an electric eel consists of three sets of abdominal organs.

Electrocytes are lined up in series in these organs. When current flows through them, it can produce an electrical discharge and deliver a shock! The electrocytes lined up, act similar to the stacked plates in a battery, to produce an electric charge. The 5000 to 6000 eletocytes, stacked neatly in electro plaques, can generate one ampere current at 500 to 650 volts (equivalent to 500 to 650 watts).

Electric eel can produce two types of electric shocks–low voltages for hunting, finding a mate, communicating and in orientation. High voltage shocks are used in self-defense and for stunning it prey. The 650 Volt electrical discharges are harmful even to a fully grown adult human. When disturbed or agitated an electric eel can go on sending shock pulses for an hour or more.

The eight foot long slimy creature, with a dull exterior and a funny face, may not appear dangerous to humans–the way a shiny coated cobra does. But appearances are deceptive! In reality, the slimy electric eel may be more dangerous than even a cobra.

[h=3]Having babies later in life may help women live longer[/h]London, June 26 (ANI): Researchers have claimed that women who embraced motherhood later in their lives have greater odds for surviving to an unusually old age. In the nested case-control study, which used Long Life Family Study data, 311 women who survived past the oldest fifth percentile of…

They had better live longer. After all there must me someone

Some of the comments in this NPR website A Shocking Fish Tale Surprises Evolutionary Biologists : NPR
are illuminating - specifically the following ones
Electric eels do indeed deliver powerful, dangerous shocks.
But if “shocks of 600 volts” were enough to kill a person, people would be dropping dead around the world from touching doorknobs, where shocks of over 20,000 volts are routinely experienced.
The eels’ prey is killed (or disabled) by the application of sufficient electric current delivered for a sufficient period of time, not by mere electric force. The Volt is a unit measure of electric force.
Journalists are incapable of apprehending even the simplest scientific facts; they are principally responsible for the public’s misunderstanding of them.
Apparently, they’re also incapable of reading past the second sentence of a Wikipedia article.

  • Marion Meads Robert Thomas• 3 hours agoI agree. It is sad to say that most journalists, more than 99% of them doesn't know the basic facts about how electricity can kill you. It is the amperage or current draw that really kills, not the voltage per se, you would need still voltage to drive the transfer of electrons, but it is the amperage or the amount of electrons traversing your body for a certain period of time that really can kill you. When we walk thru a carpet and touched a metal object, or as we disembark our cars on dry wintry days and touched the handle, we regularly get jolts of several thousand to sometimes hundred thousand volts of electricity, but the current draw of electrostatic forces are in the microampere range, so we often do not even feel it. You can survive a million volts passing through your body while a 1 volt can kill you easily, and it depends on the amperage. Thus it is meaningless to discuss energy releases and how fatal electricity is in terms of Voltage without discussing the amperage. Voltage times amperage is the amount of energy transferred per unit time. The bigger the energy transfer, the more fatal it will be.

Once I got a shock from the domestic supply 220Volts and ran howling from the front room to my mother who was working in the kitchen - in the other end of the house. I was ~ 20 years at that time.

If door knobs can get charged to 20K volts, I bet they will send our electric sparks when we walk by and give us a severe shock unless we are protected by shoes with non conducting soles.

G.D Naidu used to add mild electric shocks to make his science exhibitions more interesting.
But they might have been a single digit volt or harmless double digits.
 
Something fishy going on here!
