(Press-News.org) Mars Express has returned images from the Phobos flyby of 9 January 2011. Mars Express passed Mars' largest moon at a distance of 100km.
The HRSC-camera recorded images of Phobos on 9 January 2011 at a distance of 100 km with a
resolution of 8.1 m/pixel. Due to the stereo viewing geometry during the flyby a small part of
the moon’s edge is only visible for the right eye resulting in odd 3D-perception in this area.
This part has been slightly adjusted for better viewing. Also, for the left eye at the left
edge of the image four small data gaps have been interpolated.
Superimposed on the HRSC-nadir image are 7 SRC-images with a resolution of about 3 m/pixel.
The Super Resolution Channel images show more details of the surface of Phobos.

Defense mechanism against bacteria and fungi deciphered
2011-01-22
Under standard laboratory conditions, the human beta-defensin 1 (hBD-1), a human antibiotic naturally produced in the body, had always shown only little activity against microbes. Nevertheless the human body produces it in remarkable quantities. The solution to the puzzle was the investigation process itself, as the research group led by Dr. Jan Wehkamp at the Dr. Margarete Fischer-Bosch Institute for Clinical Pharmacology of the Stuttgart-based Robert Bosch Hospital found out.
Before the research group took a new approach to this research, defensins were usually tested ...
NFL linemen recover from back surgery, and so can you
2011-01-22
CHICAGO --- If NFL linemen can recover from back surgery and return to their spine-bruising careers, so can you get back into your "game" of horsing around with your kids or working out at the gym after back surgery.
That's the good news from a new Northwestern Medicine study that found 80 percent of NFL lineman – whose spines are especially vulnerable to degeneration – were able to return to play many more games after the surgery. These elite athletes spend a lot of time in a squatting stance that puts tremendous stress on their spine.
The study is encouraging ...
Mindfulness meditation training changes brain structure in 8 weeks
2011-01-22
Participating in an 8-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy and stress. In a study that will appear in the January 30 issue of Psychiatry Research: Neuroimaging, a team led by Massachusetts General Hospital (MGH) researchers report the results of their study, the first to document meditation-produced changes over time in the brain's grey matter.
"Although the practice of meditation is associated with a sense of peacefulness and physical relaxation, practitioners have long ...
Islands in the sky: How isolated are mountain top plant populations?
2011-01-22
Do mountain tops act as sky islands for species that live at high elevations? Are plant populations on these mountain tops isolated from one another because the valleys between them act as barriers, or can pollinators act as bridges allowing genes to flow among distant populations?
Dr. Andrea Kramer and colleagues from the Chicago Botanic Garden and the University of Illinois at Chicago were interested in pursuing these questions, particularly for a genus of plants, Penstemon (Plantaginaceae), endemic to the Great Basin region of the Western United States. They published ...
Researchers discover how to tame hammering droplets
2011-01-22
CAMBRIDGE, Mass. -- A water hammer can occur when a valve is suddenly opened or closed in a pipe carrying water or steam, causing a pressure wave to travel down the pipe with enough force that it can sometimes cause the pipes to burst. Now, new research shows that a similar effect takes places on a tiny scale whenever a droplet of water strikes a surface.
MIT's Kripa Varanasi, co-author of a report on the new finding published this week in the journal Physical Review Letters, says the phenomenon could help engineers design more durable condensing surfaces, which are used ...
Study of nutrition, Alzheimer's links hampered by research approach
2011-01-22
CORVALLIS, Ore. – Research is trying to determine whether Alzheimer's disease might be slowed or prevented with nutritional approaches, but a new study suggests those efforts could be improved by use of nutrient "biomarkers" to objectively assess the nutrient status of elderly people at risk for dementia.
The traditional approach, which primarily relies on self-reported dietary surveys, asks people to remember what they have eaten. Such surveys don't consider two common problems in elderly populations – the effect that memory impairment has on recall of their diet, or ...
Aquatic food web tied to land
2011-01-22
Millbrook, NY – A distant relative of shrimp, zooplankton are an important food source for fish and other aquatic animals. Long characterized as algae feeders, a new study published this week in the Proceedings of the National Academy of Sciences reports that nearly a third of zooplankton diets are supported by material that originates on land in lake watersheds.
The study brings scientists one step closer to clarifying the role that watershed inputs play in aquatic food webs. While it has been recognized that animals living at the bottom of lakes and streams rely, in ...
Scientists find industrial pollutants in Eastern Lake Erie carp
2011-01-22
BUFFALO, N.Y. -- Researchers from Upstate New York institutions, including the University at Buffalo, have documented elevated levels of two industrial pollutants in carp in eastern Lake Erie, adding to the body of scientific work demonstrating the lasting environmental effects of human activity and waste disposal on the Great Lakes.
The two contaminants the scientists studied were polychlorinated biphenyls (PCBs), manmade organic compounds once used in products including motor oils, adhesives, paints, plastics, pigments and dyes, and polybrominated diphenyl ethers (PBDEs), ...
2 bacterial enzymes confer resistanceto common herbicide, say MU researchers
2011-01-22
COLUMBIA, Mo. – In an article in the Nov. 23 issue of the journal The Proceedings of the National Academy of Science, researchers with Dow AgroSciences and the University of Missouri report on two bacterial enzymes that, when transformed into corn and soybeans, provide robust resistance to the herbicide 2,4-D. The discovery may soon provide Missouri corn and soybean growers a solution to the growing problem of herbicide-resistant weeds.
The spread of herbicide resistance has become an increasing concern for growers because undesired plants, such as Palmer amaranth and ...
Dow AgriSciences, MU researcher develop a way to control 'superweed'
2011-01-22
COLUMBIA, Mo. – They pop up in farm fields across 22 states, and they've been called the single largest threat to production agriculture that farmers have ever seen. They are "superweeds" – undesirable plants that can tolerate multiple herbicides, including the popular gylphosate, also known as RoundUp – and they cost time and money because the only real solution is for farmers to plow them out of the field before they suffocate corn, soybeans or cotton. Now, thanks to the work of researchers at Dow AgroSciences, LLC, who have been collaborating with a University of Missouri ...
