Stellar Fireworks Through Hubble's Eyes
Nearly 12.5 million light-years away, in the dwarf galaxy NGC 4449, stellar fireworks on display have been captured by the Hubble Space Telescope. Cells From Amniotic Fluid Used To Tissue-engineer A New Trachea
Researchers at Children's Hospital Boston report using tissue engineering to reconstruct defective windpipes in fetal lambs, first using cells from the amniotic fluid to grow sections of cartilage tube, and then implanting these living grafts into the lambs while still in the womb. The technique is one of several pioneered at Children's that use the fetus's own cells -- unspecialized mesenchymal stem cells -- to create patches to fix birth defects, in this case even before birth. Emerging Viral Infections
Avian flu is on the rise again. Should this strain cross the species barrier and become infectious between people, scientists are warning we could face a pandemic far worse than SARS. David Bradley reported for the Royal Society in 2004 on the nature of emerging viral infections. Cigarette Smoking Exacerbates Alcohol-induced Brain Damage
A study in the December issue of Alcoholism: Clinical &Experimental Research has found that cigarette smoking can both exacerbate alcohol-induced damage as well as independently cause brain damage. Popular Prostate Cancer Treatment May Encourage Spread Of Cancer, Stud
A popular prostate cancer treatment called androgen deprivation therapy may encourage prostate cancer cells to produce a protein that makes them more likely to spread throughout the body, a new study suggests. This is a preliminary finding. WMRC Library Reference Guides: Chromated Copper Arsenate (CCA) Treated
This data-rich site sheds light on the toxic danger presented by pressure-treated lumber that is commonly sold for outdoor uses such as playground equipment, benches, and picnic tables. Users can find links to consumer information, precautions, and research papers detailing the "health and environmental impacts of CCA and arsenic, risk-assessment information, and environmental cleanup alternatives."From the Waste Management and Research Center (WMRC), Illinois Department of Natural Resources. [Funny] A referee has sent himself off in an English amateur league ma
Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Convention Against Torture and Other Cruel, Inhuman or Degrading Treat
Text of this declaration that went into effect in 1987. Also includes an alphabetic list of ratifying nations, declarations and reservations, and information about the Committee against Torture, which was established to monitor the convention's implementation.

Sugar-based markers on human sperm cells which may prevent them from being attacked by the female immune system could provide a vital clue to how some cancers spread in the human body. The new research analyzed these markers which are believed to tell the female immune system that the sperm are not dangerous pathogens, and therefore should not be attacked by the woman's white blood cells during the reproductive process. Sunflower Speciation Highlights Roles For Transposable Elements In Evo
In a finding that furthers our understanding of how hybridization may contribute to genome changes and the evolution of new species, researchers have found that the genomes of three sunflower species that arose in evolution as hybrids of the same two parental types have undergone a massive proliferation of genetic entities known as transposable elements.
