A gene mutation dating back to 11,600 B.C. is the second oldest human disease mutation discovered so far. The investigators described the mutation in people of Arabic, Turkish and Jewish…

Plants are capable of synthesizing anoverwhelming variety of low-molecular-weight organic compounds, termed“secondary metabolites”, usually with very unique and complex structures. Theyrepresent one…

The most abundant and important molecules in all living organisms are proteins; after all they manage to participate in every single one of life’s essential reactions. So it is easy to see why…

I could clone you and there's probably nothing you could do to stop me. Similarly, I could clone Einstein and as far as I know, there would be no way anyone could stop me legally. Human cloning is…

Before human embryonic stem cells can be examined for therapeutic potential it must be determined whether or not transplanted cells can functionally integrate into target organs or tissues. Human…

Scientists were able to curb weight gain, improve metabolism and improve the efficacy of insulin in mice by engineering them to express a specific human enzyme, IKKbeta, in their fat tissue, but…

The enemy of my enemy is my friend, an old saying goes.  Roman, Arabic or Chinese, it doesn't matter who claims to have credit for immortalizing it first, people have known it to be true since…

Red blood cells regenerate every four months but the lining of the intestine regenerates itself every few days. The cells that help humans absorb food are constantly being produced and the various…

Experiments have recently supported a longstanding hypothesis that explains how males can survive with only one copy of the X chromosome, a hotly debated topic in science. Women have two X…

When the DNA sequences of Homo sapiens and Pan troglodytes were sequenced, the difference between the sequences of coding genes was smaller than expected based on the phenotypic differences between…
