Researchers at Johns Hopkins have discovered that a tiny piece of genetic code apparently goes where no bit of it has gone before, and it gets there under its own internal code.

Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. This applies also to fish populations. Previous studies demonstrating a link between global warming and declining fish stocks were based entirely on statistical data. However, in order to estimate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is the key factor limiting the stock size of a fish species under heat stress.

A new study shows that more people were at risk of anthrax infection in the Oct. 2001 attack on U.S. Sen. Tom Daschle's office than previously known. The research is published in the January 15 issue of The Journal of Infectious Diseases, now available online. On the other hand, the study shows, prompt intervention with antibiotics and vaccination appeared to be highly effective against the disease.

Understanding how the human brain learns to perceive objects is one of the ultimate challenges in neuroscience. In 2003, Pawan Sinha, a professor at the Massachusetts Institute of Technology, launched an initiative with the hopes of shedding some light on the acquisition of visual skills. The goal of his "Project Prakash" is to find, treat, and study congenitally blind children in India. A unique case study that resulted from this project appears in the December 2006 issue of Psychological Science.
