Understanding Dyscalculia and How the Brain Processes Numbers

Understanding-Dyscalculia-How-the-Brain-Processes-Numbers

Dyscalculia is a learning disability, which is sometimes called number blindness, and similar to dyslexia, but for numbers. Researchers estimate that as much as 7% of the population has dyscalculia, which can be marked by severe difficulties in dealing with numbers despite otherwise normal intelligence.

Fear of Immune Response to Induced Stem Cells Overstated

Induced pluripotent stem cells

Scientists report that induced pluripotent stem cells (iPS) have a similar immune response in mice as embryonic stem cells (ES).

Epigenetics Are Important To Evolutionary Success

Genetic diversity and long periods of time are things that are crucial for evolutionary adaptation. This made scientists wonder why invasive species, lacking genetic diversity, succeed quickly. And some ecologists are beginning to think that epigenetic factors might be modifying genes while leaving the genome intact.

Babies Begin Learning Language in Womb

Babies-Begin-Learning-Language-in-Womb

Newborn babies only a few hours old are able to differentiate between sounds from their native language and a foreign one. A new study indicates that babies begin absorbing language while still in the womb, earlier than previously thought.

EU’s Carbon Capture and Storage Problem

EU's-Carbon-Capture-and-Storage-Problem

Europe has a carbon-trading market and tougher emission targets, making it appear somewhat more responsible than the rest of the world at climate-policy negotiations. But recently, the region has fallen behind North America in the effort demonstrate systems for capturing greenhouse-gas emissions from power plants and industry, even as its coal use increases.

The phenomenon of cathodoluminescence gave geologists an easy way to identify quartz and other minerals in rock samples. Cathodoluminescence allows a piece of quartz to glow icy blue when put under an electron scanning microscope. Now, scientists have used this phenomenon to probe into nanostructures.

Scientists have discovered the reason why the skin on human fingers and toes shrivels up when soaked in water. Laboratory tests confirmed that wrinkly fingers improve the grip on wet or submerged objects, working away the water like rain treads in car tires.

Possible Planetary Disasters That Could Cause Extinction

Planetary-Disasters-That-May-Cause-Extinction

In the last 40,000 years, there have been at least ten gigantic landslides of more than 100 cubic kilometers in the North Atlantic ocean alone. Each of these was capable of producing waves tens to hundreds of meters in height and according to a new report, this is only one of the many possible planetary disasters that could cause extinction.
