Evidence that Venus is volcanically active

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 ...

Estrogen possible risk factor in disturbed heart rhythm

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.

Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today

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...

Mild fever helps clear infections faster, new study suggests

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

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.

Filling a niche: Neural stem cells help maintain their microenvironment

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

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.

Designing more useful bacteria

In a step forward for genetic engineering and synthetic biology, researchers have modified a strain of Escherichia coli bacteria to be immune to natural viral infections while also minimizing the potential for the bacteria or their modified genes to escape into the wild.

Mental landscapes: Magnificent wiring

For a functioning brain to develop from its embryonic beginnings, so much has to happen and go exactly right with exquisite precision, according to a just-so sequence in space and time. It's like starting with a brick that somehow replicates and differentiates into a hundred types of building materials that also replicate, while simultaneously self-assembling into a handsome skyscraper replete...
