Research shows gene defect's role in autism-like behavior
Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism.
For young birds, getting stressed out can be a good thing
Many studies have found that high levels of hormones that are associated with stress are a sign of poor fitness and reduced chance of survival -- but recent research on young songbirds found that some elevated hormones can be a good thing, often the difference between life and death.

Study adds to evidence daily aspirin linked to lower cancer mortality
A new study published in JNCI by several American Cancer Society researchers provides additional support for a potential benefit of daily aspirin use for cancer mortality, but the authors say important questions remain about the size of the potential benefit.
Rooting out rumors, epidemics, and crime -- with math
A team of EPFL scientists has developed an algorithm that can identify the source of an epidemic or information circulating within a network, a method that could also be used to help with criminal investigations.

A large-scale review of national patient records reveals that although survival rates are the same, the cost of treating trauma patients in the western United States is 33 percent higher than the bill for treating similarly injured patients in the Northeast.
Sparse microwave imaging: A new concept in microwave imaging technology
Sparse microwave imaging is a new microwave imaging concept that aims to address the paradox between growing performance requirements and increasing system complexity by introducing sparse signal processing theory to microwave imaging.
