Scripps research scientists show protein accelerates breast cancer progression in animal models

...udy found that the inappropriate expression of PTN produced breast cancers of a more aggressive subtype. In those same mouse models, highly malignant cells of scirrhous carcinoma-a hard, fibrous tumor-were found to express very high levels of the mouse mammary tumor virus (MMTV)-Ptn transgene along with incre...

Children of smokers have more than 5 times higher levels of a nicotine toxin

...r doubled the amount of cotinine, one of chemicals produced when the body breaks down nicotine from inhaled smoke to get rid of it. Sleeping with parents and lower temperature rooms were also associated with increased amounts of cotinine. Cotinine was measured in 100 urine samples taken from infants ag...

Mather also will discuss NASA's plans for the next great telescope in space, the James Webb Space Telescope. Planned for launch in 2013, the new telescope wi...

Innovative subsea separation technology wins 2007 EUREKA environmental award

... into the sea. Every day, up to 100.000 barrels of produced water with some residual small oil droplets will instead be re-injected into a separate subsea well. If such oil discharges could be avoided ijn more offshore oilfields, the benefits will be considerable. This technology meets industrys needs, too, a...

Fever after smallpox vaccination tied to individual genetic variations

...es in mice have shown that immune system molecules produced by the IL-1 and IL-18 genes are linked to tissue damage in viral myocarditis, raising the question of whether a more severe complication of smallpox vaccination might be associated with variations in these genes. Although none of the study participan...

Changes in chromosomal constitution of preimplantation embryos suggest caution in genetic screening

... and found to have normal chromosomal make-up, and produced more than 6 good quality embryos. Even in cases that fulfil these conditions, we nevertheless prefer transferring more embryos back to the uterus rather than carrying out PGS biopsies for them on day 3, assuming that natural selection will usually fa...

...eishmaniasis, respectively, with the sequence they produced in 2005 for L. major, which causes a less severe, cutaneous form of the disease. Despite the major differences in disease type, only 200 out of more than 8000 genes present in each genome were found to be differentially distributed between the three ...

Brain activity was monitored through an electroencephalograph (EEG), which records electrical signals on the surface of the brain. The musical compositions were analyzed based on the melody, harmony, rhythm...

In nature, proteins sweep up nanoparticles

... We found that the mineral aggregates, which are produced as a consequence of microbial activity, actually contain a lot of protein, says Banfield. This is very interesting because biomineralization has traditionally been thought of as a phenomenon that occurs within a cell, or in contact with it. But in th...

Human activities increasing carbon sequestration in forests

Early forest growth puts a severe nitrogen stress on the ecosystem initially, and then the forest continues to grow and ...

To handle the massive amounts of data produced by the many ENCODE teams, Stamatoyannopoulos teamed up with Dr. William Noble, UW associate professor of genome sciences and computer science. Together, they created new computational techniques and used powerful computers to unravel the locations of...

Researchers examine carbon capture and storage to combat global warming
