Iowa State University researcher discovers Ebola's deadly secret
Research at Iowa State University has led scientists to uncover how the deadly Zaire Ebola virus decoys cells and eventually kills them. view more (2010-01-20)
Researchers discover molecular security system that protects cells from potentially harmful DNA
Researchers at the University of Minnesota have discovered a molecular security system in human cells that deactivates and degrades foreign DNA. This discovery could open the door to major improvements in genetic engineering and gene therapy technologies. view more (2010-01-11)
Rules governing RNA's anatomy revealed
University of Michigan researchers have discovered the rules that dictate the three-dimensional shapes of RNA molecules, rules that are based not on complex chemical interactions but simply on geometry. view more (2010-01-08)
Unusual protein modification involved in muscular dystrophy, cancer
With the discovery of a new type of chemical modification on an important muscle protein, a University of Iowa study improves understanding of certain muscular dystrophies and could potentially lead to new treatments for the conditions. view more (2010-01-04)
Fat collections linked to decreased heart function
Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions. view more (2009-11-16)
Iowa State University researcher uncovers potential key to curing tuberculosis
Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. Researchers have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis. view more (2009-10-02)
Novel 'on-off switch' mechanism stops cancer in its tracks
A tiny bit of genetic material with no previously known function may hold the key to stopping the spread of cancer, researchers at Yale School of Medicine and Sichuan University in Chengdu, China report in two papers in the September 7-11 issue of Proceedings of the National Academy of Sciences. view more (2009-09-24)
UBC scientists find new way to extract diluted and contaminated DNA
University of British Columbia researchers have developed a new way to extract DNA and RNA from small or heavily contaminated samples that could help forensic investigators and molecular biologists get to "the truth." view more (2009-08-11)
Researchers identify new function for protein missing in Duchenne muscular dystrophy
Researchers at the University of Minnesota and National Institutes of Health have identified a new function for the protein missing in people with the most common and ultimately lethal form of childhood muscular dystrophy. view more (2009-08-04)
Airway cells use 'tasting' mechanism to detect and clear harmful substances
The same mechanism that helps you detect bad-tasting and potentially poisonous foods may also play a role in protecting your airway from harmful substances, according to a study by scientists at the University of Iowa Roy J. and Lucille A. Carver College of Medicine. view more (2009-07-27)
Short Stressful Events May Improve Working Memory
Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory. view more (2009-07-24)
Sticky protein helps reinforce fragile muscle membranes
A new study by scientists at the University of Iowa shows why muscle membranes don't rupture when healthy people exercise. view more (2009-07-24)
New information about DNA repair mechanism could lead to better cancer drugs
Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. view more (2009-07-17)
UAB Researchers Draft 3-D Protein Map
A new three-dimensional computer protein map is helping researchers at the University of Alabama at Birmingham (UAB) unravel the biological pathways that control brain-cell death after a stroke. view more (2009-06-25)
UNC study identifies genetic cause of most common form of breast cancer
The discovery of tumor-suppressor genes has been key to unlocking the molecular and cellular mechanisms leading to uncontrolled cell proliferation - the hallmark of cancer. view more (2009-05-12)
ISU researcher identifies key function in protein, cell transcription
When cells decide to make proteins, key building blocks of all organisms, they need to know where to start reading the instructions for assembling them. view more (2009-05-04)
Scientists discover how to improve immune response to cancer at Princess Margaret Hospital
A team of scientists at The Campbell Family Institute for Breast Cancer Research (CFIBCR) at Princess Margaret Hospital and international collaborators have discovered how to trigger an improved immune response to cancer that could be included in new clinical trials that use a patient's own cells to destroy tumours. view more (2009-04-27)
Molecule tracking reveals mechanism of chromosome separation in dividing cells
University of Washington (UW) researchers are helping to write the operating manual for the nano-scale machine that separates chromosomes before cell division. view more (2009-03-09)
Cholesterol-reducing drugs may lessen brain function, says ISU researcher
Research by an Iowa State University scientist suggests that cholesterol-reducing drugs known as statins may lessen brain function. view more (2009-02-24)
While focusing on heart disease, researchers discover new tactic against fatal muscular dystrophy
Based on a striking similarity between heart disease and Duchenne muscular dystrophy, researchers at Columbia University Medical Center have discovered that a new class of experimental drugs for heart failure may also help treat the fatal muscular disorder. view more (2009-02-09)
