In the past few years, as imaging tools and techniques have improved, scientists have been working tirelessly to build a detailed map of neural connections in the human brain—with the ultimate hope of understanding how the mind works.

Researchers Identify How Yersinia Spreads within Infected Organs

Posted: 16 Sep 2013 06:47 AM PDT

Researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have identified how one type of bacteria, Yersinia, immobilizes the immune system in order to grow in the organs of mice. To do so, the researchers extended the use of a technique and suggest that it could be used to study other bacteria that use the same or similar means of infection. The study is published in the September 11 issue of Cell Host & Microbe.

New Model Should Expedite Development of Temperature-Stable Nano-Alloys

Researchers from North Carolina State University have developed a new theoretical model that will speed the development of new nanomaterial alloys that retain their advantageous properties at elevated temperatures.
The model correctly predicted the material on the left would not be stable at high temperatures and that the material on the right would be stable.
