For assessing severe trauma, single-pass whole-body computed tomography (CT) can prove but not definitively exclude the presence of injuries and should be performed later than 30 minutes after admission to an emergency department for optimal results, according to a study in CMAJ (Canadian Medical Association Journal). Traumatic injury, caused by major traffic collisions or a fall from a height, for example, has a significant impact on health care costs, illness and death. In North America...

Scientists at the Centre for Addiction and Mental Health (CAMH) have identified a potential target for the development of anti-craving medications for people with addictions to stimulants such as methamphetamine. The discovery centers on a brain receptor related to the chemical dopamine, which has a complex role in addictive behaviors. Using brain scans and a novel chemical probe developed in CAMH's Research Imaging Centre, CAMH scientists found that the probe had high levels of binding...

Facilitates systematic comparison of mouse models of disorders including schizophrenia, autism A new technology developed by neuroscientists at Cold Spring Harbor Laboratory (CSHL) transforms the way highly detailed anatomical images can be made of whole brains. Until now, means of obtaining such images — used in cutting-edge projects to map the mammalian brain -- have been painstakingly slow and available only to a handful of highly specialized research teams. By automating and...

Image 1 - Prehistoric Mite Caught Hitching A Ride On A Spider

Scientists have produced amazing three-dimensional images of a prehistoric mite as it hitched a ride on the back of a 50 million-year-old spider. At just 176 micrometers long and barely visible to the naked eye, University of Manchester researchers and colleagues in Berlin believe the mite, trapped inside Baltic amber (fossil tree resin), is the smallest arthropod fossil ever to be scanned using X-ray computed tomography (CT) scanning techniques. They say their study — published...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
