NASA announced on Wednesday that its Stardust-NExT spacecraft will rendezvous with comet Tempel 1 on Valentine's Day. The space agency said that the mission will allow scientists to look for changes on the comet's surface that took place after an orbit around the sun. The spacecraft will take high-resolution images during the encounter, and will attempt to measure the composition, distribution, and flux of dust emitted into the coma. According to NASA, the mission will expand the...

The biological effects of general anesthesia are more closely related to those of a coma than natural sleep, claims a new study published in Thursday's edition of the New England Journal of Medicine. While often times doctors and patients describe being under anesthesia as something similar to going to sleep, the researchers behind the new study have found "significant differences" between the two states, Julie Steenhuysen of Reuters reported on Wednesday. For example, while sleep usually...

Eighty-six days out from its appointment with a comet, NASA's Stardust spacecraft fired its thrusters to help refine its flight path. The Stardust-NExT mission will fly past comet Tempel 1 next Valentine's Day (Feb. 14, 2011). It will perform NASA's second comet flyby within four months. "One comet down, one to go," said Tim Larson, project manager for both the Stardust-NExT mission and the EPOXI mission -- which successfully flew past comet Hartley 2 on Nov. 4. The trajectory correction...

Findings may help prevent brain damage in vulnerable patients Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO. ECMO, used to temporarily oxygenate the blood of patients whose heart and lungs are too weak or damaged to do so on their own, is most often used as a...

Initial science results on comet released from University of Maryland, much more to come UMD scientists say. One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-led EPOXI mission as it zipped past comet Hartley 2 last week is that dry ice is the 'jet' fuel for this comet and perhaps many others. Images from the flyby show spectacular jets of gas and particles bursting from many distinct spots on the surface of the comet. This is the...

Patients with a severe traumatic brain injury (and not in shock because of blood loss) who received out-of-hospital administration of hypertonic fluids (a solution with increased concentration of certain electrolytes and thought to help reduce intracranial pressure) as initial resuscitation did not experience better 6-month neurologic outcomes or survival compared to patients who received a normal saline solution, according to a study in the October 6 issue of JAMA. Traumatic brain injury...

ESA's Rosetta mission needs to deliver its lander, Philae, to a site in the southern hemisphere of comet 67P/Churyumov-Gerasimenko, according to a new study of the comet's nucleus. "Southern sites appear to be both the safest and the most scientifically interesting," said Jeremie Lasue, who presented the findings at the European Planetary Science Congress in Rome on Thursday September 23rd. "Churyumov-Gerasimenko is a time capsule holding material from the birth of the Solar System.  The...

A new national guideline, co-authored by a Henry Ford Hospital neurologist, has created an updated step-by-step process to help physicians better wade through the complex process of determining brain death in adult patients. The guideline is set to appear in the June 8 issue of Neurology, the medical journal of the American Academy of Neurology (AAN). The new AAN guideline is an improvement over the group's 1995 guideline, because it includes a check-list for physicians based on scientific...

Scientists put the Comet Wild 2 under the microscope Researchers at the University of Leicester are examining extraterrestrial material from a comet to assess the origins of our Solar System. For the first time ever, material samples from a comet were collected in the Stardust Mission. It was the first mission since the Apollo landings to have successfully returned extraterrestrial material for scientists to study in the laboratory. At the University of Leicester's Space Research Centre and...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
