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...

Study tests if familiar voices can heal traumatic brain injuries Karen Schroeder's voice, recorded on a CD, reminded her son, Ryan, of his 4-H project when he was 10 and decided to raise pigs. "You bid on three beautiful squealing black and white piglets at the auction," she said softly. "We took them home in the trunk of our Lincoln Town Car, because we didn't have a truck." Recordings from Ryan's mother, father or sister were played through headphones for him four times a day. They were...

Scientists from the Max Planck Institute for Solar System Research identify the active regions on the surface of comets Studying comets can be quite dangerous - especially from close up. Because the tiny particles of dust emitted into space from the so-called active regions on a comet's surface can damage space probes. Scientists from the Max Planck Institute for Solar System Research in Germany have now developed a computer model that can locate these regions using only the information...

British scientists have identified a new candidate for the biggest comet measured to date. Dr Geraint Jones of UCL's Mullard Space Science Laboratory will be presenting the results at the RAS National Astronomy Meeting in Glasgow on Tuesday April 13th. Instead of using the length of the tail to measure the scale of the comet, the group has used data from the ESA/NASA Ulysses spacecraft to gauge the size of the region of space disturbed by the comet's presence. Analysis of magnetometer data...

Just three days shy of one year before its planned flyby of comet Tempel 1, NASA's Stardust spacecraft has successfully performed a maneuver to adjust the time of its encounter by eight hours and 20 minutes. The delay maximizes the probability of the spacecraft capturing high-resolution images of the desired surface features of the 2.99-kilometer-wide (1.86 mile) potato-shaped mass of ice and dust. With the spacecraft on the opposite side of the solar system and beyond the orbit of Mars, the...

A study by British and Belgian researchers found that a man who had been presumed to be in a vegetative state for five years, can communicate "yes" and "no" using only his thought patterns, Reuters reported. The researchers said the man sustained a severe traumatic brain injury in a traffic accident in 2003. He remained physically unresponsive and was presumed to be in a vegetative state for five years. The study results, published in the authoritative New England Journal of Medicine, said...

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...
