Evidence that Venus is volcanically active
- ScienceDaily
- 23/3/15 19:39
Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows. Venus, although similar to Earth in size and mass, differs markedly in that it does not have plate tectonics. The boundaries of Earth's moving surface plates are the primary locations of ...
East Coast, US, landslide impacts from Puerto Rico to Vermont and in between

Estrogen possible risk factor in disturbed heart rhythm
- ScienceDaily
- 23/3/15 19:38
The sex hormone estrogen has a negative impact on heartbeat regulation, according to an experimental study. Estrogen impact seems to interact with hereditary changes causing a heart disease disturbing the heart's rhythm, while other endogenous substances may have a protecting effect.

- ScienceDaily
- 23/3/15 18:25
Researchers are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured in the shoe and thus during any activity. This helps athletes or patients to determine performance and therapy progress.
Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
- ScienceDaily
- 23/3/15 18:24
Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant...
Memories could be lost if two key brain regions fail to sync together, study finds
- ScienceDaily
- 23/3/15 18:24
Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study has found.
Mild fever helps clear infections faster, new study suggests
- ScienceDaily
- 23/3/15 18:24
It may be better to let a mild fever run its course instead of automatically reaching for medication, new University of Alberta research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down...
Minimizing electric vehicles' impact on the grid
- ScienceDaily
- 23/3/15 18:24
Some projections show that widespread adoption of electric vehicles might require costly new power plants to meet peak loads in the evening. A new study shows that placing EV charging stations strategic ways and setting up systems to initiate charging at delayed times could lessen or eliminate the need for new power plants.
New research establishes how and why Western diets high in sugar and fat cause liver disease
- ScienceDaily
- 23/3/15 18:24
New research has established a link between western diets high in fat and sugar and the development of non-alcoholic fatty liver disease, the leading cause of chronic liver disease.
Filling a niche: Neural stem cells help maintain their microenvironment
- ScienceDaily
- 23/3/15 18:24
Researchers shed light on the neural stem and progenitor cell (NSPC) microenvironment during development. Neurosphere formation from embryonic mouse forebrain NSPCs was significantly increased under low oxygen conditions, and VEGF-A was identified as a factor released by NSPCs to contribute to this effect. This study demonstrates that NSPCs appear to maintain their own niche and population under...
Filming proteins in motion
- ScienceDaily
- 23/3/15 18:24
Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. Naturally, scientists have devoted a lot of research to understanding and manipulating proteins.
How moms and dads view each other as co-parents affects kids
- ScienceDaily
- 23/3/15 18:24
How mothers and fathers see each other as co-parents of their children plays a key role in how well-adjusted their kids become, a new study suggests.
Where did Earth's water come from? Not melted meteorites, according to scientists
- ScienceDaily
- 23/3/15 18:24
A new study brings scientists one step closer to answering the question of where Earth's water came from.
Researchers control the degree of twist in nanostructured particles
