A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet. It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. "Our findings suggest that PET imaging can reveal cognitive processes that aren't...

Mars-Bound Siding Spring Comet Sprouts Multiple Jets

NASA NASA released on Thursday an image of a comet that, on Oct. 19, will pass within 84,000 miles of Mars - less than half the distance between Earth and our moon. The image on the left, captured  March 11 by NASA's Hubble Space Telescope, shows comet C/2013 A1, also called Siding Spring, at a distance of 353 million miles from Earth. Hubble can't see Siding Spring's icy nucleus because of its diminutive size. The nucleus is surrounded by a glowing dust cloud, or COMA, that measures...

WASHINGTON, Jan. 24, 2014 /PRNewswire-USNewswire/ -- Three NASA science instruments are being prepared for check-out operations aboard the European Space Agency's Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus in November. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Rosetta was reactivated Jan. 20 after a record 957 days in hibernation. U.S. mission managers are scheduled to activate their instruments on the...

Vegetative Patients Recognize Loved ones
2013-12-17 08:29:25

redOrbit Staff & Wire Reports - Your Universe Online Patients in a vegetative state may be able to recognize photographs of their family and friends, according to a new study published this month in the journal PLOS ONE. Although patients in a vegetative state are awake, can breathe on their own, and appear to go in and out of sleep, they do not respond to what is happening around them, and exhibit no signs of conscious awareness. Since communicating with these patients is...

Searching For What Is Left OF Comet ISON
2013-12-05 08:56:07

NASA Just prior to its closest approach to the sun on November 28, Comet ISON went through a major heating event, and likely suffered a major disruption. At this time, scientists are not sure how much of the comet survived intact. We may be seeing emission from rubble and debris in the comet's trail, along its orbit, or we may be seeing the resumption of cometary activity from a sizable nucleus-sized chunk of ISON. Most agree that up to 90 percent of ISON was destroyed, leaving...

Comet ISON Shows Signs Of Life After Close Encounter With Sun
2013-11-29 11:26:44

Lawrence LeBlond for redOrbit.com - Your Universe Online Last night astronomers were putting the final nail in the coffin for Comet ISON, which had been streaking toward its close encounter with the sun for months, culminating with a perihelion (closest approach of the sun) on Thanksgiving Day. Described as the “comet of the century” by some and predicted to just “fizzle out” by others, ISON has been a hot topic since it was first discovered by Russian astronomers on September...

Comet ISON May Or May Not Put On A Show

[ Watch the Video: ISON Keeps Giving Us The Run-Around ] Alan McStravick for redOrbit.com - Your Universe Online I’ve been nerding out for most of the year, since Comet ISON first came on my radar, so to speak. Back in February, I wrote a piece for redOrbit detailing the discovery of a comet so magnificent that its show was going to be the stuff of legend. And then in July, redOrbit’s Brett Smith tried to rain on my astral parade when he reported on the diminished expectations...

Our definitions of death, specifically the death of the human brain, may have to change in the near future. This initial exchange between Bioquark Inc., a novel development stage company focused on biological approaches to human regeneration and repair, and Dr. Calixto Machado, MD, PhD, a world leading researcher in brain death, coma, and vegetative states, is an important step in realization of the transformational changes that are coming.

Awareness May Be Possible When In A Vegetative State
2013-11-03 04:35:27

Alan McStravick for redOrbit.com - Your Universe Online The concept of being in a coma or vegetative state is only made the more frightening when you add in the possibility that while lying there, hooked to medical equipment and having one’s life prolonged by a support system, a cognizance of one’s surroundings damns you to a waking nightmare of unknown duration. Thankfully, those in a vegetative state are spared this scenario. Or are they? According to a new study, a patient who...

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...
