Tempe, AZ (Scicasts) — By understanding the secret of how lizards regenerate their tails, researchers may be able to develop ways to stimulate the regeneration of limbs in humans.
Edinburgh, Scotland (Scicasts) — Babies suffering from bacterial infections like sepsis could benefit from better treatment, thanks to a ground-breaking study.
La Jolla, CA (Scicasts) — Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms.
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.
Cambridge, UK (Scicasts) — Breast cancer risks for one of potentially the most important genes associated with breast cancer after the BRCA1/2 genes were reported Aug. 06 in the New England Journal of Medicine. Women with mutations in the PALB2 gene have on average of one in three chance of developing breast cancer by the age of seventy.
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.
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.
Durham, NC (Scicasts) —Researchers have hijacked a defence system normally used by bacteria to fend off viral infections and redirected it against the human papillomavirus (HPV), the virus that causes cervical, head and neck, and other cancers.
Jupiter, FL (Scicasts) — Research conducted at the Florida campus of The Scripps Research Institute (TSRI) has discovered links between a set of genes known to promote tumour growth and mucoepidermoid carcinoma, an oral cancer that affects the salivary glands.
Tucson, AZ (Scicasts) — An international team of researchers led by the University of Arizona has sequenced the complete genome of African rice.
