...called "functional imaging" to see when the memory formed in the flys brain. "Before training, we could see some calcium flowing into the mushroom body neurons when the flies were exposed to odor," said Davis. When they exposed the fruit flies or Drosophila to the odor 24 hours after spaced training, the...Jefferson researchers develop combined procedure for uterine preservation in treating fibroids
...ory of a 35-year-old women whose numerous fibroids formed a large mass in her pelvic area that, when initially diagnosed, was of a size comparable to a full-term pregnancy. "Traditionally, treatment for such a large fibroid mass in the uterus has been limited to hysterectomy, because the patient would ble...Special ES&T issue examines effects of emerging contaminants on people, planet

As a result, NDMA and a co-contaminant, perchlorate, which also is used in rocket fuel and munitions, often infiltrate ground water near aerospace facilities.

Ridge 2000 was formed in 2001 as an interdisciplinary effort to study the geology, chemistry and biology of the poorly understood process by which the Earth's crust is formed.

After the 2005 study, says Karlseder, "We formed a hypothesis that after telomeres replicate they need to be detected by the internal DNA damage machinery--otherwise they cannot form a protective structure, or chromosomal cap."
