Taking Race Out of Human Genetics

The concept of race is not a scientific category
Science
In the wake of the sequencing of the human genome in the early 2000s, genome pioneers and social scientists alike called for an end to the use of race as a variable in genetic research (1,2). Unfortunately, by some measures, the use of race as a biological category has increased in the postgenomic age (3). Although inconsistent definition and use has been a chief problem with the race concept, it has historically been used as a taxonomic categorization based on common hereditary traits (such as skin color) to elucidate the relationship between our ancestry and our genes. We believe the use of biological concepts of race in human genetic research—so disputed and so mired in confusion—is problematic at best and harmful at worst. It is time for biologists to find a better way. (...)

Scientific journals and professional societies should encourage use of terms like “ancestry” or “population” to describe human groupings in genetic studies and should require authors to clearly define how they are using such variables. It is preferable to refer to geographic ancestry, culture, socioeconomic status, and language, among other variables, depending on the questions being addressed, to untangle the complicated relationship between humans, their evolutionary history, and their health.

Blue Martian Sunset


Sunset on Mars

On May 19, 2005, NASA's Mars Exploration Rover Spirit captured this view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th Martian day. Because Mars is farther away, the Sun is less bright and only about two thirds the size seen from planet Earth.

Rio de Janeiro 45º

Tony Goes
I wish I could "Fear no more the heat o' the sun".
But how could this be possible if there's no rain, 
we must save energy and the air seems to burn?

Christmas Mistery

Merry Christmas!



On the Nativity of Christ

Today the Virgin gives birth to him who is above all being,

and the earth offers a cave to him whom no one can approach.

Angels with shepherds give glory, and magi journey with a star,

for to us there has been born a little Child, God before the ages.

(Kontakion, by Romanos the Melodist - 752)

Kids killed in Pakistan


God is Good. 
God is Merciful. 
God doesn't reward murderers.
What does really move assassins that take the lives of God's creatures?


Let's pray for the mothers and fathers of the students killed in Pakistan.

You are my HoneyBunch Sugarplum





You're my Honeybunch, Sugarplum
Pumpy-umpy-umpkin,

You're my Sweetie Pie
You're my Cuppycake, Gumdrop
Snoogums-Boogums, You're
the Apple of my Eye

And I love you so and I want you to know
That I'll always be right here
And I love to sing sweet songs to you
Because you are so dear
