The second derivative is everywhere in finance. It is convexity in bonds or gamma in options. When someone blows up in the financial world, it is usually a failure to understand the second derivative.

Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that ...

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study.

Mendez and colleagues reported the identification of a Y chromosome haplotype (the A00 lineage) that lies at the basal position of the Y chromosome phylogenetic tree. Incorporating this haplotype ...

The Y chromosome is very different from X and the 22 other chromosomes of the human genome. It is smaller and bears few genes (only 27 compared to about 1,000 on the X).
