A genetic mutation related to a more aggressive form of breast cancer occurs four times more often in African American patients than their white counterparts, Yale researchers report in the August 9, 2004 online edition of the journal Cancer.
In the United States, African-American women have a lower incidence of breast cancer than white women, but they have a higher mortality rate. The disease also develops at an earlier age and is more aggressive in African-American women. To explore the reasons for the differences, Beth A. Jones, assistant professor in the Department of Epidemiology and Public Health at Yale School of Medicine, and her colleagues studied the effects of alterations in a tumor suppressor gene called p53.
The team looked at how the patterns of alterations of genes related to worse prognosis differed between African-American and white women. They examined the breast tumors of 145 African-American and 177 white women and found that African-American women were four times more likely than white women to show significant alterations in the p53 gene.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
