Variations in genetic code affect social behavior

Why are some people shy while others are outgoing? A study in the current issue of Science demonstrates for the first time that social behavior may be shaped by differences in the length of seemingly non-functional DNA, sometimes referred to as junk DNA.

Humans more prone to cancer than chimpanzees

Chimpanzees and humans share a common ancestor, and even today 99 percent of the two species' DNA is identical. But since the paths of man and chimp diverged 5 million years ago, that one percent of genetic difference appears to have changed humans in an unexpected way: It could have made people more prone to cancer.

Common genetic mutation that increases the risk of inheriting Hirschsprung disease

Gene hunters at Johns Hopkins have discovered a common genetic mutation that increases the risk of inheriting a particular birth defect not by the usual route of disrupting the gene's protein-making instructions, but by altering a regulatory region of the gene. Although the condition, called Hirschsprung disease, is rare, its complex genetics mimics that of more common diseases, such as diabetes and heart disease.

Fifteen-year hunt uncovers gene behind pseudothalidomide syndrome

A team of scientists from Colombia, the United States and elsewhere has successfully completed a 15-year-plus search for the genetic problems behind the very rare Roberts syndrome, whose physical manifestations often include cleft lip and palate and shortened limbs that resemble those of babies whose mothers took thalidomide during pregnancy.

Ebola virus outbreaks linked to infected wild animal carcasses

All recent Ebola virus outbreaks in humans in forests between Gabon and the Republic of Congo were the result of handling infected wild animal carcasses, according to a study by the Wildlife Conservation Society (WCS) and its regional partners

Modern humans have sloppy gene control mechanisms which can make us susceptible to diseases

Our evolutionary ancestors’ lack of choice in the mating game has left modern humans exposed to disease, according to new research published in the journal PLOS Biology today.

Evolution has been working very hard to produce us humans

The genes that regulate brain development and function evolved much more rapidly in humans than in nonhuman primates and other mammals because of natural selection processes unique to the human lineage. Researchers reported their findings in the cover article of the Dec. 29, 2004, issue of the journal Cell.

MRI reveals similarities between the human and chimpanzee brain

New MRI-based studies present more evidence that the brains of chimpanzees are human-like in terms of the relationships among brain asymmetry, handedness and language, according to research undertaken at the Yerkes National Primate Research Center in Atlanta.

Crystal structure of protein AIRs kinase uncovered

Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.

Grant to develop high speed DNA sequence reader

Sequencing of the human genome is one of the major scientific advances of our time. But with 3 billion base pairs, initial sequencing of the human genome took 11 years and cost $1 billion to complete in 2002. Today, it costs up to $50 million to sequence 3 billion base pairs.
