A gene's first 'kiss' sets off that affair known as puberty
...uman development. And while there is a fairly good understanding
of how the endocrine system regulates the hormones involved, just how and when the brain activates this process has been a great mystery. An appreciation of puberty's deep-seated neurobiological mechanisms could, for instance, help prevent precocious...
Man and mouse share genome structures
... This global activation may have implications for understanding
mechanisms behind certain cancers, Bernstein believes. For example, proteins that place methyl groups on histones can, when mutated, cause leukemia. Bernstein hopes to apply the new technology to characterize chromatin structure in leukemic cells and...
Molecular biology fills gaps in knowledge of bat evolution
...search, Kent, U.K. "The present work advances our understanding
of where bats originated, when they diversified and how different bat families are related to each other," Springer said. "It also quantifies the fraction of the fossil record that is missing for bats." The team, using DNA sequencing, analyzed data ...
UCSB scientists probe sea floor venting to gain understanding of early life on Earth
New keys to understanding

Dysentery uses 'sword and shield' to cause infection
... Dr Tang adds: "This discovery greatly expands our understanding
of how bacteria are sometimes able to evolve although it is unlikely to result in new treatments or vaccines for dysentery. In this case, the dysentery bacteria has evolved into a highly effective and dangerous infection." ...
