Can New Plasma-Based Biomaterials Speed Healing of Injured Tissues?

Posted: 15 Apr 2013 08:37 AM PDT

Platelet-rich plasma (PRP) derived from blood contains growth factors and other bioactive molecules that promote healing at sites of tissue injury. However, it is difficult to deliver and retain these molecules at a target site, and clinical results have proven to be mixed – until now. A new solid form of bioactive plasma-based biomaterials, known as PBMs, can accelerate tissue healing.

Research Finds Invasive Kudzu Bugs May Pose Greater Threat Than Previously Thought

The invasive kudzu bug has the potential to be a major agricultural pest, causing significant damage to economically important soybean crops. Conventional wisdom has held that the insect pests will be limited to areas in the southern United States, but new research from North Carolina State University shows that they may be able to expand into other parts of the country.

Day or night, driving while tired a leading cause of accidents

Get more sleep. Have another cup of coffee before you drive to school or work. It could save your life.

A 100-car naturalistic driving study conducted by the Virginia Tech Transportation Institute has shown that fatigue is a cause of 20 percent of crashes, rather than the 2 or 3 percent previously estimated based on surveys, simulator studies, and test tracks.
