A new form of genetic testing of the bacteria that causes tuberculosis can provide better information on TB transmission and also trace TB outbreaks more accurately than the current standard test, according to a study from Germany published in this week's PLOS Medicine. A team of researchers led by Stefan Niemann from Forschungszentrum Borstel, Molecular Mycobacteriology, compared the results of the two types of tests on 86 M. tuberculosis isolates from a TB outbreak in the German states...

redOrbit Staff & Wire Reports - Your Universe Online Scientists say they have put together a more complete string of genetic letters that may control how well parrots learn to imitate their owners and other noises. Researchers unraveled the certain regions of the parrots' genome using a new technology, single molecule sequencing, and fixing its flaws with data from older DNA-decoding devices. Researchers also decoded hard-to-sequence genetic material from corn and bacteria as proof...

Results from the first use of this technique in the clinic The first report of the diagnostic use of the technique of exome sequencing, where short sequences of DNA are analyzed, shows that it can give good results at low cost, a researcher from The Netherlands will tell the annual conference of the European Society of Human Genetics today (Monday). The scientists were able to perform a genetic diagnosis in around 20% of 100 cases of patients with intellectual disability (ID) and 50% of...


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.
