Astronomers and supporters from eight institutions around the country who are developing the Giant Magellan Telescope (GMT) will gather at The University of Arizona Steward Observatory Mirror Lab on Saturday, July 23, to celebrate the casting of the first of seven 8.4- meter (27-foot) mirrors for the facility.

With this casting, the GMT becomes the first extremely large ground-based telescope to start construction.

The GMT will feature six giant off-axis mirrors around

New search method could aid in the discovery of biomarkers

Using a super-efficient method they invented to search for a type of cancer-related change in all genes of a cell, Dana-Farber Cancer Institute researchers have discovered new evidence about how the “microenvironment” of breast cancers helps drive the cancers’ growth and migration.

The scientists found that non-cancerous cells surrounding young breast cancers — the microenvironment — undergo epigenetic mo

Researchers at the San Raffaele Hospital (Milan, Italy) published unexpected results of studies in which immature nerve cells (adult mouse neural stem cells) injected into the blood of mice with MS-like disease were able to suppress the immune attacks that damage the brain and spinal cord tissues. The study, funded in part by the National MS Society, is being reported by Drs. Stefano Pluchino, Gianvito Martino and colleagues in the July 14, 2005 issue of Nature. These surprising findings, if confi

A systematic search through human genes has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those involved in cell division (mitosis) and to answer fundamental questions of how cell division is regulated.

The scientists will use a method called ‘RNA interference (RNAi)’ where chemically synthes

MADISON-Boosting levels of two critical proteins that normally shut down during Huntington’s disease, researchers at the University of Wisconsin-Madison and the Cold Spring Harbor Laboratory have cured fruit flies of the genetic, neurodegenerative condition.

Forms of the same proteins-known in short form as CREB and HSP-70–exist in all cells, including those of humans.

The study results, published online today by the Proceedings of the National Academy of Sciences

For asthmatics and for anyone with respiratory problems, air pollution can significantly impair simple everyday activities. NASA is trying to tie together satellites and stations on the ground to develop a “sensor web” to track this pollution and improve air quality forecasts.

Understanding how tropospheric or near-surface-level ozone is produced, distributed and transported from city to city, region to region and continent to continent is an important step toward improving the
