Researchers create 3D model of the pulmonary acinus

Amidst the extraordinarily dense network of pathways in a mammal lung is a common destination. There, any road leads to a cul-de-sac of sorts called the pulmonary acinus. This place looks like a bunch of grapes attached to a stem (acinus means "berry" in Latin).

Optics Express publishes new paper on smart micromanipulation aided robotic-surgical tool

Even the most skilled and steady surgeons experience minute, almost imperceptible hand tremors when performing delicate tasks. Normally, these tiny motions are inconsequential, but for doctors specializing in fine-scale surgery, such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients.

MiR-214 plays a critical role in regulating ovarian cancer stem cell properties

Researchers at Moffitt Cancer Center have discovered that the micro ribonucleic acid miR-214 plays a critical role in regulating ovarian cancer stem cell properties. This knowledge, said the researchers, could pave the way for a therapeutic target for ovarian cancer.

PRI examines India's efforts to combat malnutrition using local product

PRI's "The World" reports on malnutrition in India, where "eight million children ... suffer from severe acute malnutrition, according to the Indian government." However, the news service writes that "when it comes to treating those children, India lacks what many consider one of the best tools available: so-called ready-to-use therapeutic foods," such as "the most well-known therapeutic food, Plumpy'Nut, ... a patented concoction of peanut butter and micro-nutrients that allows severely malnourished children to be treated at home instead of at a hospital."

MiR-34a plays a key role in obesity

Scientists have identified a key molecular player in a chain of events in the body that can lead to fatty liver disease, Type II diabetes and other metabolic abnormalities associated with obesity. By blocking this molecule, the researchers were able to reverse some of the pathology it caused in obese mice.

Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

Whole-genome sequencing can track origin and movement of TB pathogens

Reconstructing the spread of killer diseases such as tuberculosis (TB) from person to person using DNA sequencing quickly identifies the origin and movement of pathogens. This approach is directly informing public health strategies to control infectious disease outbreaks, says a scientist speaking at the Society for General Microbiology's Autumn Conference at the University of Warwick.
