Addicted to Ran, Ovarian Cancer Cells Stop Moving When Deprived

Universite de Montreal

Researchers have shown the key role that a protein called Ran plays in the mobility of ovarian cancer cells: they demonstrated these cells cannot migrate from cancerous sites without the help of Ran.

Pitt/UPMC to Lead $19.2 Million Trial to Test Red Cell Exchange in Sickle Cell Disease

Health Sciences at the University of Pittsburgh

Patients with sickle cell disease experience severe organ damage leading to early death. An international clinical trial funded by the NIH will test whether red cell exchange, which replaces sicked red blood cells with normal ones could prevent or reverse organ damage and prolong life.

Instability in Antarctic Ice Projected to Make Sea Level Rise Rapidly

Georgia Institute of Technology

Instability hidden within Antarctic ice is likely to accelerate its flow into the ocean and push sea level up at a more rapid pace than previously expected. Even if images of vanishing Arctic ice and mountain glaciers are jarring, their potential contributions to sea level rise are nowhere near Antarctica’s.

Rising Tundra Temperatures Create Worrying Changes in Microbial Communities

Georgia Institute of Technology

Rising temperatures in the tundra of the Earth’s northern latitudes could affect microbial communities in ways likely to increase their production of greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests.

Yearlong Birth Control Supply Would Cut Unintended Pregnancies, Costs

Health Sciences at the University of Pittsburgh

By dispensing a year's worth of birth control pills up front, the VA could prevent 583 unintended pregnancies and save $2M per year on health care costs each year.

Public Perception of Scientific Uncertainty Is Linked to HPV Vaccine Policy Support

University of Chicago Medical Center

Public perceptions about how scientific evidence supporting the HPV vaccine is portrayed in society and media may influence whether individuals support public health measures to increase HPV vaccination.

Tiny Supersonic Jet Injector Accelerates Nanoscale Additive Manufacturing

Georgia Institute of Technology

By energizing precursor molecules using a tiny, high-energy supersonic jet of inert gas, researchers have dramatically accelerated the fabrication of nanometer scale structures. The rapid additive manufacturing technique also allows them to produce structures with high aspect ratios. Now, a theory developed to describe the technique could lead to new applications for additive nanomanufacturing and new nanoscale materials.

Breaking Bad: Tiny Change Has Big Effects, Reverses Prediabetes in Mice

University of Utah Health

A small chemical change – shifting the position of two hydrogen atoms – makes the difference between mice that are healthy and mice with insulin resistance and fatty liver, major risk factors for diabetes and heart disease. Making the change prevented the onset of these symptoms in mice fed a high-fat diet and reversed prediabetes in obese mice. The finding highlights the role of ceramides in metabolic health and pinpoints a “druggable” target that could be used to develop new therapies for metabolic disorders.

Immune-Boosting Compound Makes Immunotherapy Effective Against Pancreatic Cancer

Washington University in St. Louis

Researchers at Washington University School of Medicine in St. Louis and Rush University in Chicago have found a compound that promotes a vigorous immune assault on pancreatic cancer. The findings, in mice, suggest a way to improve immunotherapy for the deadly disease in patients.

First Complete Wiring Diagram of an Animal’s Nervous System

Albert Einstein College of Medicine

In a study published online today in Nature, researchers at Albert Einstein College of Medicine describe the first complete wiring diagram of the nervous system of an animal, the roundworm Caenorhabditis elegans, used by scientists worldwide as a model organism. The study includes adults of both sexes and reveals substantial differences between them.
