In a recent article published in Ultrasound, the Journal of the British Medical Ultrasound Society (Vol. 15, Number 3, 2007), Dr. Hylton Meire raises the possibility that ultrasound is not as useful as has been suggested. He particularly emphasises the lack of scientific data to support the use of fetal "nuchal thickness" measurements in routine clinical ultrasound practice to ascertain the presence of Down's syndrome.

   09-25-2007 · EurekAlert!
   Researchers in Australia have shown that positron emission tomography that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumor's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival. The research was presented at the European Cancer Conference in Barcelona today.

2. Transcutaneous cervical esophageal ultrasound can not substitute for 24-h pH monitoring or manometry
   10-09-2007 · EurekAlert!
   Gastroesophageal reflux arises from increased exposure and/or sensitivity of the esophageal mucosa to gastric contents, and affects 5-40 percent of the population. Esophageal ultrasound studies in GER have mainly focused on the evaluation of the gastroesophageal junction and esophageal motility performed by transabdominal or endoluminal routes. Visualizing refluxate in transcutaneous cervical esophageal ultrasound was found to be useful as a pre-diagnostic tool for estimating GER and/or manometric pathology in 71.1 percent of adults.

   Think for a moment about what you have done so far today -- made a cup of tea, driven to work, sent an e-mail or text. Each of those activities is dependent on oil, from fuel for transport to the plastic parts of your kettle, car, keyboard and mobile. Development of our high-impact consumer lifestyles is accelerating even as fossil-fuel supplies are dwindling, and the environmental impact of their use becomes ever more apparent.

   Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was formed. They concluded that extinctions resulting when one ocean became two were delayed by 2 million years.

   Think you haven't got the aptitude to learn a foreign language? In a new Northwestern University study, neuroscientists predict which study participants would be more successful second language learners simply by measuring a small brain structure. The measurement is taken even before study participants are given any form of language training. The study demonstrating a link between biology and second language learning appears online today, in an article in Cerebral Cortex.
