Newly created cancer stem cells could aid breast cancer research
...rently after acquiring the same mutations. Ince confirmed this behavioral difference by taking a single human breast tissue sample, splitting it in two and growing the cells in the two culture mediums, which select for different cells. Next, he transformed the two populations with the same tumor-initiating ...Brain blood flow gives clues to treating depression
...ion about both structure and functioninvestigators confirmed already published findings that cerebral blood flow in depressed patients is lower than in healthy control subjects, especially in frontal, limbic and subcortical brain regions. We wanted to see whether improvement in clinical depression is accompani...Study: Sticking to the sand might not be such good, clean fun for beachgoers
...ith the sand they had collected. What they found confirmed their hypothesis: The concentration of bacteria in the sand decreased, while its presence in the seawater increased after it flowed through the sand samples. The team then returned to Lovers Point to research the movement of bacteria from sand to s...UCLA scientists produce functioning neurons from human embryonic stem cells
...how much prodding can be done. Sun and her team confirmed that the two embryonic stem cell lines were different through gene expression analysis neurons that perform different functions in different parts of the brain express different genes. The cell line prone to becoming neurons found in the forebrain e...Discovery of new protein could provide new understanding of male fertility
...e proteins by working with E2 and E3 enzymes. They confirmed that this was indeed the case. Groettrup and his team also tested whether UBE1L2 was like the original E1 expressed in all organs and tissues. They measured the expression levels of UBE1L2 in mice and found that the protein was expressed about fi...... Costes's initial model, following the NASA model, confirmed random distribution of double-strand breaks at the micron scale. The frequency of DSBs was radiation dependent, however: in the case of cosmic rays (NASA's main concern), which lead to complex double-strand breaks, there was good agreement with the R...Neurosciences and music meet in Montreal

...that miR-21 probably targeted PTEN, and this study confirmed that. Furthermore, the researchers showed that adding high levels of miR-21 to normal liver cells caused PTEN levels to drop. They also traced the chemical pathways that increased the cells' abilities to proliferate, migrate and invade other tissu...First case of successful ovarian tissue transplantation between two, nonidentical sisters

A year after the transplant, the doctors retrieved two mature oocytes from her ovary and fertilised them with her husbands sperm via ICSI (intracytoplasmic sperm......me type VIIC). After Brendon ORourke and Dr Berg confirmed and defined the disorder in Australian White Dorper flocks at the Elizabeth Macarthur Agricultural Institute (EMAI) at Camden in 2006, they then developed a DNA test to screen individual sheep for the defective gene.
