Cells can turn on tumor-promoting growth circuits by falsely reporting critical genetic information during the process of transcription: making RNA from DNA.Damage to the DNA making up a gene can lead to a misreading of the gene as it is made into RNA, a process called transcriptional mutagenesis.Transcriptional mutagenesis could represent an additional way DNA damage contributes to tumor formation.

Quantum computers would likely outperform conventional computers in simulating chemical reactions involving more than four atoms, according to scientists at Harvard University, the Massachusetts Institute of Technology and Haverford College. Such improved ability to model and predict complex chemical reactions could revolutionize drug design and materials science, among other fields.

A new study from Georgia Tech shows that when patients with macular degeneration focus on using another part of their retina to compensate for their loss of central vision, their brain seems to compensate by reorganizing its neural connections. Age-related macular degeneration is the leading cause of blindness in the elderly. The study appears in the December edition of the journal Restorative Neurology and Neuroscience.

Preliminary results of the University of Minnesota’s independent academic study of the I-35W bridge collapse suggest that lack of robustness in the bridge’s original design, additional load from bridge improvements over the years, weight from construction materials and stresses induced by temperature changes contributed to the collapse of the I-35W bridge on Aug. 1, 2007.

Islet cell transplantation is a promising therapy for people with type 1 diabetes, but it requires a regime of powerful immunosuppressive drugs so the immune system won’t reject the insulin-producing islets. The drugs raise the risk of infections and cancer and are toxic to the islets themselves. Northwestern researchers have developed a new technique that eliminated the need for these drugs. The strategy is a potential therapy for human islet cell transplantation.
