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. Neuroscientists believe that the disorder illuminates the inner workings of […]

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. The scientists presented their findings at a meeting of […]

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). The scientists published their findings in the journal Nature┬╣. Back in 2007, scientists first reported that cells could be reprogrammed to an embryo-like state. Medical researchers wanted to use these iPS cells to create an […]

The Possibility of Life on Extrasolar Moons

Life-possible-on-extrasolar-moons

A new study examines the probability of life existing on extrasolar moons, identifying tidal heating as a criterion for exomoon habitability and devising a theoretical model to estimate the minimum distance a moon could be from its host planet and still allow habitability. 10 January 2013. In their search for habitable worlds, astronomers have started […]

Drug Resistant Gonorrhea on the Rise in North America

Common-STD-Resistance-On-The-Rise-in-North-America

The most common STIs in the USA, chlamydia and gonorrhea, are usually easy to eradicate thanks to doses of oral antibiotics, but now gonorrhea is getting more resistant to first line defense drugs. The scientists published their findings in The Journal of the American Medical Association┬╣. There are more than 321,000 cases of gonorrhea reported […]

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. The scientists published their findings in the journal Acta Paediatrica. Sensory and brain mechanisms for hearing […]

EU’s Carbon Capture and Storage Problem

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

Europe’s carbon-trading market and tougher emission targets make 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. Europe has had trouble […]
