Has the heaviest element been found?

Could a superheavy element - heavier than anything previously found in nature or made in the lab - exist naturally in the rocks of Earth? A team of physicists says they have detected a few exceptionally massive atoms - which they say could be element 122 - in a solution prepared from natural minerals. But other scientists are highly sceptical of the claim.

Asteroids - How real is the threat?

The Doomed and the Blind

As politicians sit squabbling in Washington, deliberating and deciding, an asteroid 4 kilometers across is thundering through space at 15 miles per second. It was forged in a galactic maelstrom millions of years ago from molten metal, and now it tumbles through space with malevolent indifference. People sit unaware of an impending disaster, carrying on their daily activities while extinction encroaches. It won't just be the extinction of a few species, or a few million people, but all life will be wiped off the face of the earth within hours. Our planet will become a barren waste for millions of years, void of vibrant life and wonder.

Is an awful scenario like this really plausible? The answer is yes. The threat is very real and the evidence is in the scars our earth bears on the surface, the massive craters on the moon, and the giant wounds on Mars. You would expect that something so catastrophic and horrible for our species and planet would demand attention from lawmakers; wrong. Although our government is well-informed by agencies like NASA, it has neglected to properly fund Near Earth Object (NEO) programs, and it could lead to our destruction. An asteroid impact is a natural disaster we can actually prevent, and if our representatives don't take steps to improve our warning systems, we will suffer the same fate as the dinosaurs.

Absinthe's Mind-Altering Mystery Solved

An analysis of century-old bottles of absinthe - the kind once quaffed by the likes of van Gogh and Picasso to enhance their creativity - may end the controversy over what ingredient caused the green liqueur's supposed mind-altering effects .

The culprit seems plain and simple: The century-old absinthe contained about 70 percent alcohol, giving it a 140-proof kick. In comparison, most gins, vodkas and whiskeys are just 80- to 100-proof.

Meteor Shower ABC

A meteoroid is a solid object - usually are dust particles or debris from comets - that floats around in space.

When meteoroid enters and burns in the Earth's atmosphere, the visible streak in the sky is known as a meteor.

A meteorite is the meteoroid that survives and reaches Earth's surface.

An increase in the number of meteors at a particular time is called a meteor shower.

If we trace back the path of the meteors during a meteor shower, we will find that all the meteors seem to originate from a point in the sky. This point is known as the radiant.

Envisioning a World Without Men

Imagine a world without men: Lauren Bacall but no Bogie, Hillary Clinton but no Bill, no Starsky or Hutch.

This isn't just an unlikely sci-fi scenario. This could be reality, according to Bryan Sykes, an eminent professor of genetics at Oxford University and author of Adam's Curse: A Future Without Men.

"The Y chromosome is deteriorating and will, in my belief, disappear," Sykes told me. A world-renowned authority on genetic material, Sykes is called upon to investigate DNA evidence from crime scenes. His team of researchers is currently compiling a DNA family tree for our species.

How the Brain Learns to Read Can Depend on the Language

For generations, scholars have debated whether language constrains the ways we think. Now, neuroscientists studying reading disorders have begun to wonder whether the actual character of the text itself may shape the brain.

Studies of schoolchildren who read in varying alphabets and characters suggest that those who are dyslexic in one language, say Chinese or English, may not be in another, such as Italian.

Fertile women 'have sexier voice'



Fertility & voice

A woman's voice becomes more alluring when she is at her most fertile, according to US research. Recordings of women taken at different points in their menstrual cycle were played to people of both sexes.

New Scientist magazine reports that the voices rated as most attractive belonged to women at peak fertility.

Study suggests link between comet bombardment and movement through the galaxy, causing mass extinctions on earth

The sun's movement through the Milky Way regularly sends comets hurtling into the inner solar system -- coinciding with mass life extinctions on earth, a new study claims. The study suggests a link between comet bombardment and the movement through the galaxy.

A large body of scientific evidence now exists that support the hypothesis that a major asteroid or comet impact occurred in the Caribbean region at the boundary of the Cretaceous and Tertiary periods in Earth's geologic history. Such an impact is suspected to be responsible for the mass extinction of many floral and faunal species, including the large dinosaurs, that marked the end of the Cretaceous period.
