<span style="background-color: rgba(255, 255, 255, 0);">In a separate session, they also tested the children face-to-face, watching if they moved their lips or counted on their fingers, for comparison with the brain data.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">The children were tested twice, roughly a year apart. As the children got older, their answers relied more on memory and became faster and more accurate, and it showed in the brain.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">The hippocampus is sort of like a relay station where new memories come in — short-term working memory — and then can be sent elsewhere for longer-term storage and retrieval.

<span style="background-color: rgba(255, 255, 255, 0);">Next, Menon's team put 20 adolescents and 20 adults into the MRI machines and gave them the same simple addition problems. It turns out that adults don't use their memory-crunching hippocampus in the same way. Instead of using a lot of effort, retrieving six plus four equals 10 from long-term storage was almost automatic, Menon said.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">In other words, over time the brain became increasingly efficient at retrieving facts. Think of it like a bumpy, grassy field, NIH's Mann Koepke explained.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">'The study provides new evidence that this experience with math actually changes the hippocampal patterns, or the connections. They become more stable with skill development,' she said.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">A group of scientists in the United States found that Ebola carries a protein called VP24 that interferes with a molecule called interferon, which is vital to the immune response.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">“One of the key reasons that Ebola virus is so deadly is because it disrupts the body’s immune response to the infection,” said Chris Basler of the Icahn School of Medicine at Mount Sinai, New York, who worked on the study. “Figuring out how VP24 promotes this disruption will suggest new ways to defeat the virus.”</span></div>

<span style="background-color: rgba(255, 255, 255, 0);">The team, lead by Gaya Amarasinghe from Washington University School of Medicine, found that VP24 works by stopping something called “transcription factor STAT1” – which carries interferon’s antiviral message – from entering the nucleus of a cell and initiating an immune response.</span></div>

Soon, the mice had fully functioning, anatomically correct corneal tissue. And they could see again.</span></div>

<span style="background-color: rgba(255, 255, 255, 0);"><strong>Why it matters:</strong> Corneal tissue loss is one of the leading causes of blindness, and <a href="http://www.who.int/mediacentre/factsheets/fs282/en/" style="text-decoration: none;">300 million people</a>are visually impaired around the world. In the past, researchers have tried using tissue and cell transplants to help regenerate corneas, but they've had mixed results. This discovery could solve that problem.</span></div>
