On any given day, there are approximately 84,000 women in federal and state prisons and nearly 70,000 additional women incarcerated in county jails, numbers that are now doubling every seven to eight years. Most of these women were custodial parents prior to their incarceration, so when they go to prison, children are often left behind.

University : 06 August, 2007
Researchers at the University have found a way to combine cancer chemotherapy with gene therapy designed to disrupt the growth of blood vessels to a tumor. The combination, tested in mice, is far more effective than standard chemotherapy and has no additional side effects. This innovative approach is described in the August issue of the Journal of Clinical Investigation.

Male-driven evolution confirmed in Li
University : 04 August, 2007
Researchers from the University have estimated that genetic mutations, the raw material for evolution, occur 5.25 times more often in males than in females. This discovery should lay to rest any doubts raised by recent studies questioning the dominant role that males play in producing mutations for molecular evolution.

Researchers in Ecology & Evolution overturned a classic belief that has been published in both genetics and evolution textbooks since the 1930s, when they reported in the Jan. 4 issue of Science that the tiny fourth chromosome of the fruit fly, believed to be identical in every member of the species, actually has several regions that vary.
 
Researchers measure importance of natural selection at genetic level
University : 03 August, 2007
Researchers from the University have demonstrated that natural selection plays a much larger role in molecular evolution than anyone had suspected. Their report, published in the Nature, shows that about 25 percent of genes are evolving rapidly in response to competitive pressures. A second paper by other researchers in the same issue confirms this discovery.

Researchers map out networks that determine cell fate
University : 26 July, 2007
A two-step process appears to regulate cell-fate decisions for many types of developing cells, according to researchers from the University. This finding sheds light on a puzzling behavior. For some differentiating stem cells, the first step leads not to a final decision but to a new choice. In response to the initial chemical signal, these cells take on the genetic signatures of two different cell types. It often requires a second signal for them to commit to a single cellular identity.

Simulation may reveal the detailed mechanics of exploding stars
University : 25 July, 2007
This supercomputer simulation from the Center for Astrophysical Thermonuclear Flashes shows the density changes in the material of a white dwarf star, a star that has burned most or all of its nuclear fuel. The star is smaller than Earth but much denser. A teaspoon of the material at its densest (shown in red), would weigh a ton on Earth. At its most diffuse (the regions in white and purple), the density becomes gaseous.

The gaseous disks of two galaxies collide in this series of images produced in a supercomputer simulation. Approximately three billion years after the collision begins, the two supermassive black holes at the center of the galaxies merge. Such mergers produce strong gravitational waves, which scientists hope to detect with the proposed Laser Interferometer Space Antenna.
