Hannover Messe 2003: Gepresste Gläser mit höchster Präzision

Das Fraunhofer-Institut für Produktionstechnologie IPT stellt auf der HANNOVER MESSE 2003 vom 7. bis 12. April 2003 ein neues Verfahren zum Präzisionsblankpressen optischer Komponenten aus anorganischen Gläsern vor. Auf einem Gemeinschaftsstand mit der IVAM NRW e. V. (Interessengemeinschaft zur Verbreitung von Anwendungen der Mikrostrukturtechniken) zeigt das Fraunhofer IPT in Halle 6, Stand C22, verschiedene strukturierte Glasoptiken, die mit der Abformtechnologie am Institut hergestellt wurden.

Black holes really are holes, astronomers say

Black holes really are holes – objects without a surface – say Drs Christine Done and Marek Gierlinski in a paper accepted for publication in the Monthly Notices of the Royal Astronomical Society. Having an “event horizon” rather than a surface is the property that makes something a black hole but, by definition, it’s impossible ever to see one directly. However, these new results give direct evidence of the existence of such holes in spacetime.

Drs Done and Gierlinski set out to track

Neighborhood layout could turn drivers into walkers

People who live in neighborhoods where stores, schools and homes are within walking or cycling distance from each other make almost twice as many weekly trips on foot as residents of less “walkable” neighborhoods, according to new research.

And all that car-free traveling can add up to better health: One or two extra walking trips a week can burn off enough calories to drop nearly two pounds in a year, which is about how much weight American adults gain annually.

Immune response depends on key molecule: Research

In a new study published in the April 1, 2003 issue of Genes and Development, scientists at University Health Network’s Advanced Medical Discovery Institute (AMDI)/Ontario Cancer Institute (OCI) have shown that a molecule called caspase-8 plays a key role in the immune system response, by controlling how T-cells are activated to respond to infections.

T-cells are white blood cells that recognize and fight off viruses and bacteria. When T-cells encounter these foreign invaders they build up

New Treatment Boosts Cancer Vaccine

The first clinical trials of a new type of cancer treatment that releases the “brakes” on immune cells indicate that this approach enhances attacks on tumors while sparing the body’s own tissue.

The results of the phase I clinical trials of cytotoxic T-lymphocyte-associated antigen 4 blockade therapy were published online on April 1, 2003, in the Early Edition of the Proceedings of the National Academy of Sciences. The researchers involved in the study included James Allison, a Howard Hughe

Vegetation essential to balancing climate models

Just as vegetables are essential to balancing the human diet, the inclusion of vegetation may be equally essential to balancing Earth’s climate models.

Scientists at MIT who were trying to create accurate models of climate change in the southern portion of the Sahara desert found that including a realistic component of vegetation growth and decay was absolutely essential. Without including the vegetation as a variable (rather than a fixed parameter), the models were not able to show the regi
