A Gene Linked to Disease Found to Play a Critical Role in Normal Memory Development

Jupiter, FL (Scicasts) — It has been more than 20 years since scientists discovered that mutations in the gene huntingtin cause the devastating progressive neurological condition Huntington’s disease, which involves involuntary movements, emotional disturbance and cognitive impairment. Surprisingly little, however, has been known about the gene’s role in normal brain activity.

Finding the Genetic Culprits that Drive Antibiotic Resistance

Hinxton, UK (Scicasts) — Researchers have developed a powerful new tool to identify genetic changes in disease-causing bacteria that are responsible for antibiotic resistance. The results from this technique could be used in clinics within the next decade to decide on the most effective treatments for diseases such as pneumonia and meningitis.

Mobile DNA Elements Restructure Cancer Genomes

Hinxton, UK (Scicasts) — Researchers have found a novel mechanism that can restructure a cancer's genome and introduce hundreds of mutations. Previously overlooked through misidentification, this mechanism, a common feature of lung and colorectal cancers, raises questions about the effect environmental factors can have on the evolution of a tumour.
