- 08/11/18 06:15
As much as a third of Mars could have been underwater, scientists say. An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient...
Gene Chips Accurately Detect Pneumonia In ICU Patients On Ventilators
- ScienceDaily
- 08/11/18 06:15
Even seasoned doctors have a difficult time diagnosing pneumonia in hospitalized patients breathing with the assistance of a ventilator. That's because a patient's underlying illness often skews laboratory test results and masks pneumonia's symptoms. Now, researchers report they have validated the use of gene chip technology to rapidly and accurately detect pneumonia associated with ventilator use...

Billions Of Particles Of Anti-matter Created In Laboratory
- ScienceDaily
- 08/11/18 06:15
Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet."
Children Distressed By Family Fighting Have Higher Stress Hormones
- ScienceDaily
- 08/11/18 06:15
A new study found that children who are very distressed when their parents fight have higher levels of the stress hormone cortisol. Distress, hostility, and level of involvement parental arguments were measured in 208 six-year olds. Cortisol levels were measured by taking saliva samples before and after simulated telephone arguments between their parents. Children who were very distressed and very...

In a new report, researchers have confirmed the accuracy and reliability of SpermCheck Vasectomy, the first FDA approved at-home immunodiagnostic test for detecting low concentrations of sperm.
Newborn Neurons In Adult Brain Can Settle In The Wrong Neighborhood
- ScienceDaily
- 08/11/18 06:15
In a study that could have significant consequences for neural tissue transplantation strategies, researchers report that inactivating a specific gene in adult neural stem cells makes nerve cells emerging from those precursors form connections in the wrong part of the adult...

Alpine Rivers Hold Important Clues For Preserving Biodiversity And Coping With Climate Change
- ScienceDaily
- 08/11/18 06:00
Marginal plants, particularly trees, play a crucial role in sustaining the biodiversity of Europe's big river systems, according to new research. This finding provides important clues for protecting Europe's rivers against a combined onslaught from human development and climate change, which are tampering with existing ecosystems and changing both the physical and biological forces acting upon...
Astronomers Detect Matter Torn Apart By Black Hole
- ScienceDaily
- 08/11/18 06:00
Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the center of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense gravity close to the central black...
Exercise Increases Brain Growth Factor And Receptors, Prevents Stem Cell Drop In Middle Age
- ScienceDaily
- 08/11/18 06:00
A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem...
