Spitzer Captures Fruits Of Massive Stars’ Labors

Tuesday, May 31st, 2005
The saga of how a few monstrous stars spawned a diverse community of additional stars is told in a new image from NASA’s Spitzer Space Telescope. The striking picture reveals an eclectic mix of embryonic stars living in the tattered neighborhood of one of the most famous massive stars in our Milky Way galaxy, Eta Carinae.

Vaccine Against Childhood Pneumonia Shows Promise

Tuesday, May 31st, 2005
A vaccine against pneumonia and invasive pneumococcal disease, a severe form of bacterial infection, can substantially reduce hospital admissions and improve the survival of children in developing countries, concludes a trial published in the March 26, 2005 issue of THE LANCET. The authors believe the vaccine should be made available to children in Africa, where rates of severe invasive pneumococcal disease are up to ten times higher than in industrialised countries.

Lipids Get New Comprehensive Classification System

Tuesday, May 31st, 2005
In response to the growing number of lipids expected to be discovered through lipidomics and in anticipation of the massive amounts of data that will be generated by the lipid community, an international group of scientists has developed a comprehensive classification, nomenclature, and chemical representation system for lipids. The details of the system appear in the May issue of the Journal of Lipid Research, an American Society for Biochemistry and Molecular Biology journal.

Elephants Imitate Sounds As A Form Of Social Communication

Tuesday, May 31st, 2005
Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today’s Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some birds, and bats.

Harmful Chemicals May Reprogram Gene Response To Estrogen

Tuesday, May 31st, 2005
New research shows that exposure to harmful chemicals and drugs during critical developmental periods early in life may actually “reprogram” the way certain genes respond to the female hormone estrogen. This genetic reprogramming may determine whether people with a genetic predisposition for a disease actually develop the disease.

Nanotechnology Combined With Superconductivity Could Pave The Way For ‘Spintronics’

Tuesday, May 31st, 2005
As the ever-increasing power of computer chips brings us closer and closer to the limits of silicon technology, many researchers are betting that the future will belong to “spintronics”: a nanoscale technology in which information is carried not by the electron’s charge, as it is in conventional microchips, but by the electron’s intrinsic spin.
