Following the Body’s Own Prescription

April 1, 2013 10:22 am | by Cynthia Fox | Articles | Comments

An intuitive approach, which co-opts the body’s own molecular machinery, has led to massive expansions of umbilical cord blood cells. It and other new approaches “will revolutionize all transplantation,” says University of Minnesota Blood and Marrow Transplantation Director John Wagner.

Stem Cell Fate Depends on ‘Grip’

March 29, 2013 10:52 am | News | Comments

A team of researchers has generated new insight on how a stem cell’s environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or bone cells depends partially on how well they can “grip” the material they are growing in.


Common Foods Cause DNA Damage

March 28, 2013 9:35 am | News | Comments

In a laboratory study pairing food chemistry and cancer biology, scientists tested the potentially harmful effect of foods and flavorings on the DNA of cells. They found that liquid smoke flavoring, black and green teas and coffee activated the highest levels of a well-known, cancer-linked gene called p53.

Counting White Blood Cells at Home

March 27, 2013 10:19 am | News | Comments

Engineers have developed a portable device to count white blood cells that needs less than a pinprick's worth of blood and takes just minutes to run.

Easier Hybridization for Microarrays

March 26, 2013 2:09 pm | by Mike May, PhD | Articles | Comments

Monoclonal Antibody Targets, Kills Leukemia Cells

March 26, 2013 10:34 am | News | Comments

Researchers have identified a humanized monoclonal antibody that targets and directly kills chronic lymphocytic leukemia (CLL) cells. The findings represent a potential new therapy for treating at least some patients with CLL, the most common type of blood cancer in the United States.

46-gene Test Can Predict Cancer Treatment Response

March 25, 2013 11:39 am | News | Comments

The first multi-gene test that can help predict cancer patients' responses to treatment using the latest DNA sequencing techniques has been launched in the NHS. The test detects mutations across 46 genes in cancer cells.


Teaming Up Against Head Injury

March 25, 2013 11:14 am | by Cynthia Fox | Articles | Comments

Under the crushing weight of many new studies finding even small head injuries can cause massive damage, the National Football League (NFL) has launched a new $60 million brain initiative. The initiative is co-sponsored by General Electric (GE).

The Neuroscience of Finding Lost Keys

March 22, 2013 10:33 am | News | Comments

Ever find yourself racking your brain on a Monday morning to remember where you put your car keys? When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments- such as that room where your keys were hiding in an unusual spot.

Inflammation: From Mummies to Melanoma

March 21, 2013 1:46 pm | by Cynthia Fox | Articles | Comments

Inflammation is stirring up headlines again. Anti-inflammatory aspirin prevented thousands more cancers. The anti-inflammatory “miracle molecule” resveratrol came back. Psychologists report inflammation is stoked by even minor tensions. And archaeologists say all this knowledge is long overdue, as even Egyptian mummies have clogged arteries. We have been plagued by inflammation since the time of the Pharaohs.

Humanoid Robot Helps Train Children with Autism

March 21, 2013 11:32 am | News | Comments

An interdisciplinary team of mechanical engineers and autism experts at Vanderbilt University have developed a system that demonstrates that robotic systems may be powerful tools for enhancing the basic social learning skills of children with autism spectrum disorder.

Researchers Publish Improved Neanderthal Genome

March 19, 2013 6:32 pm | by FRANK JORDANS - Associated Press - Associated Press | News | Comments

Researchers in Germany said Tuesday they have completed the first high-quality sequencing of a Neanderthal genome and are making it freely available online for other scientists to study. The genome produced from remains of a toe bone found in a Siberian cave is far more detailed than a previous Neanderthal genome sequenced three years ago by the same team.

The Quest to Mimic Spider Silk

March 19, 2013 1:29 pm | by Skip Derra | Articles | Comments

To many people, spider webs are a nuisance, something that needs to be knocked down and cleared out of the way. They’re reminders that you haven’t cleaned lately. To Jeffery Yarger, spider webs, and more specifically the spider silk that makes up the webs, are structures of beauty, especially when you look at them at the microscopic level.

Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find.

Dual Approach May Bring Universal Flu Shot

March 15, 2013 9:44 am | News | Comments

Researchers report that influenza virus-specific CD8+ T cells or virus-specific non-neutralizing antibodies are each relatively ineffective at conferring protective immunity alone. But, when combined, the virus-specific CD8 T cells and non-neutralizing antibodies cooperatively elicit robust protective immunity.

The Importance of Genomics for Cancer Research

March 14, 2013 10:20 am | by Ruth Burton, PhD, Product Manager Genomic Solutions, Oxford Gene Technology | Articles | Comments

Despite significant advances, cancer remains one of the predominant causes of mortality in the modern world, and as such has remained a top research priority. It is a complex and continually evolving genetic disease and, as such, requires sophisticated tools for study.

Nobel Aspirations

March 6, 2013 3:53 pm | by Cynthia Fox | Blogs | Comments

Over the last few months, the Nobel Prize has generated much controversy—again. More than 3,000 scientists contributed to the most high profile science event of 2012: the discovery of the Higgs boson subatomic particle. Yet the Nobel can only be split between three laureates. Was the Nobel Prize finally obsolete, the press fretted, in one angst-ridden blog after another?
