(Phys.org)—There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer precision? Scientists at the Vienna University of Technology developed a method to attach molecules at exactly the right place. When biological tissue is grown, this method can allow the positioning of chemical signals, telling living cells where to attach. The new technique also holds promise for sensor technology: A tiny three dimensional "lab on a chip" could be created, in which accurately positioned molecules react with substances from the environment.
A new study reports that nearly seven percent of urologic multi-detector computed tomography (MDCT) scans for hematuria result in incidental findings that may be clinically important for the patient.
Some RNA molecules spend time in a restful state akin to hibernation rather than automatically carrying out their established job of delivering protein-building instructions in cells. This restful period appears to be a programmed step for RNA produced by certain types of genes. Protein production in cells is not as clear-cut as biology textbooks suggest, scientists say.

Global platelet reactivity is more effective than responsiveness to clopidogrel in identifying acute coronary syndrome (ACS) patients at high risk of ischemic events, according to new research.
Up to 400 cardiac events and 200 deaths in Swedish PCI patients could be avoided by following a heart healthy lifestyle, according to new research.
Patients who resume smoking after a stroke increase their risk of death by three-fold, according to new research. The researchers also found that the earlier patients resume smoking, the greater their risk of death with one year.

The benefits of breast milk have long been appreciated, but now scientists have described a unique property that makes mother's milk better than infant formula in protecting infants from infections and illnesses. The finding explains how breast milk, but not infant formula, fosters colonies of microbiotic flora in a newborn's intestinal tract that aid nutrient absorption and immune system development.
