With abdominal etching, plastic surgeons help patients get 'six-pack abs'  

Even with a good diet and workout routine, some men and women have trouble getting the toned abdominal appearance they want. For these patients, a technique called abdominal etching can help in creating the classic 'six-pack abs' physique in men or three-vertical-line abdomen in women, reports a new study.

Overlooked molecular machine in cell nucleus may hold key to treating aggressive leukemia  

Many people fighting a very aggressive form of acute myeloid leukemia (AML) don't survive more than five years. These very sick patients are often unable to receive the only cure -- a bone marrow transplant. Now, an international team of scientists report on a long-overlooked part of a leukemic cell's internal machinery, where they may have found a key to treating the aggressive blood cancer.

Protecting damaged hearts with microRNAs  

Once the heart is formed, its muscle cells have very limited ability to regenerate. After a heart attack, these cells die off and scar tissue forms, potentially setting people up for heart failure. A new study advances the possibility of using microRNAs -- small molecules that regulate gene function -- to regenerate heart muscle. In mice, two microRNAs that are abundant in developing hearts, miR-19a and miR-19b, repaired heart muscle and improved cardiac function after heart attack.

A low-tech problem troubles the high-tech world of digital pathology imaging: There are no reliable standards for the quality of digitized tissue slides comprising the source material for computers reading and analyzing vast numbers of images. Poor-quality slides get mixed in with accurate slides, potentially confusing a computer program trying to learn what a cancerous cell looks like. Researchers are trying to fix this, sharing an open-source quality control standard.

Growing a cerebral tract in a microscale brain model  

An international research team modeled the growth of cerebral tracts. Using neurons derived from stem cells, they grew cortical-like spheroids. In a microdevice, the spheroids extended bundles of axons toward each other, forming a physical and electrical connection. Fascicles grew less efficiently when one spheroid was absent, and when a gene relevant to cerebral tract formation was knocked-down. The study further illuminates brain growth and developmental disorders.
