NASA identifies ice cloud above cruising altitude on Titan

25/10/2014 | CIENCIA ON LINE
NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/I...

NASA's Fermi satellite finds hints of starquakes in magnetar 'storm'

25/10/2014 | CIENCIA ON LINE
NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing this data have discovered underlying signals related to seismic waves rippling throughout the...

Illusions in the cosmic clouds: New image of spinning neutron star

25/10/2014 | CIENCIA ON LINE
Pareidolia is the psychological phenomenon where people see recognizable shapes in clouds, rock formations, or otherwise unrelated objects or data. There are many examples of this phenomenon on Earth and in space. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/N...

MAVEN ultraviolet image of comet Siding Spring's hydrogen coma

25/10/2014 | CIENCIA ON LINE
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft obtained this ultraviolet image of hydrogen surrounding comet C/2013 A1 Siding Spring on Oct. 17, 2014, two days before the comet's closest approach to Mars. The Imaging Ultraviolet Spectrograph (IUVS) instrument imaged the comet at...

Mars Orbiter's spectrometer shows Oort comet's coma

25/10/2014 | CIENCIA ON LINE
The Compact Imaging Spectrometer for Mars (CRISM) observed comet C/2013 A1 Siding Spring as the comet sped close to Mars on Oct. 19. CRISM recorded imaging data in 107 different wavelengths, showing the inner part of the cloud of dust, called the coma, surrounding the comet's nucleus. Fuente :...

Without swift influx of substantial aid, Ebola epidemic in Africa poised to explode

24/10/2014 | CIENCIA ON LINE
The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research predicts. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/e...

3-D map of the adolescent universe

23/10/2014 | CIENCIA ON LINE
Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice of the adolescent universe. The map shows a web of hydrogen gas that varies from low to high density at a time when the universe was made of a...

Novel software application can stratify early-stage non-small cell lung cancer patients

23/10/2014 | CIENCIA ON LINE
Computer-Aided Nodule Assessment and Risk Yield, is a novel software tool that can automatically quantitate adenocarcinoma pulmonary nodule characteristics from non-invasive high resolution computed tomography images and stratify non-small cell lung cancer patients into risk groups that have...

Anaplastic lymphoma kinase immunohistochemistry testing comparable to, if not better than, fluorescence in situ hybridization testing

23/10/2014 | CIENCIA ON LINE
Sixteen institutions across Europe collaborated together to show for the first time that a semi-quantitative anaplastic lymphoma kinase protein expression test, immunohistochemistry, is reliable amongst several laboratories and reviewers when test methodology and result interpretation are...

Desert streams: Deceptively simple

23/10/2014 | CIENCIA ON LINE
Volatile rainstorms drive complex landscape changes in deserts, particularly in dryland channels, which are shaped by flash flooding. Paradoxically, such desert streams have surprisingly simple topography with smooth, straight and symmetrical form that until now has defied explanation. Fuente :...

Titan glowing at dusk and dawn

22/10/2014 | CIENCIA ON LINE
New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one. Fuente :...

Finally: Missing link between vitamin D, prostate cancer

22/10/2014 | CIENCIA ON LINE
A new study offers compelling evidence that inflammation may be the link between vitamin D and prostate cancer. Specifically, the study shows that the gene GDF-15, known to be upregulated by vitamin D, is notably absent in samples of human prostate cancer driven by inflammation. Fuente :...

Real-time tracking system developed to monitor dangerous bacteria inside body

22/10/2014 | CIENCIA ON LINE
Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, researchers working with mice report they have devised a way to detect and monitor in real time infections with dangerous Gram-negative bacteria. These increasingly drug-resistant bacteria are...

Paralyzed patients have weaker bones, higher risk of fractures than expected

22/10/2014 | CIENCIA ON LINE
People paralyzed by spinal cord injuries lose mechanical strength in their leg bones faster, and more significantly, than previously believed, putting them at greater risk for fractures from minor stresses, according to a study by researchers. The results suggest that physicians should begin...

Bipolar disorder discovery at the nano level

22/10/2014 | CIENCIA ON LINE
A nano-sized discovery helps explain how bipolar disorder affects the brain and could one day lead to new drug therapies to treat the mental illness, researchers report. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/5...

NASA Webb's heart survives deep freeze test

22/10/2014 | CIENCIA ON LINE
After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA's Goddard Space Flight Center in...

New feather findings get scientists in a flap

22/10/2014 | CIENCIA ON LINE
Scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight. Since their appearance over 150 million years ago, feather shafts (rachises) have evolved to...

Special microscope captures defects in nanotubes

21/10/2014 | CIENCIA ON LINE
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. Carbon nanotubes have been touted as exceptional materials with unique properties that allow for extremely efficient charge and energy transport, with the...

Competition keeps health-care costs low, U.S. researchers find

21/10/2014 | CIENCIA ON LINE
Medical practices in less competitive health-care markets charge more for services, according to a study. The study, based on U.S. health-care data from 2010, provides important new information about the effects of competition on prices for office visits paid by preferred provider organizations,...

Smoking interferes with neurocognitive recovery during abstinence from alcohol

21/10/2014 | CIENCIA ON LINE
Researchers know that alcohol-dependent individuals (ALC) sustain neurocognitive impairment even after detoxification. A new study examines specific domains of cognitive recovery in conjunction with smoking status. Findings show that smoking status influenced the rate and level of neurocognitive...
