Working Together to Reduce ‘Severe’ Suffering—It Can Be Done!

August 3, 2015 | by Penny Hawkins BSc, PhD | Blogs | Comments

While the debate about animal research and testing can become pretty heated in the public arena, the research community and scientific animal welfare organizations have a long history of identifying common ground and working constructively together to replace, reduce and refine animal use.

Muscle Fibers Grown in Lab Offer New Muscular Dystrophy Model

August 3, 2015 1:41 pm | by Brigham and Women's Hospital | News | Comments

In a new study, investigators report that by identifying and mimicking important developmental cues, they have been able to drive cells to grow into muscle fibers, producing millimeter-long muscle fibers capable of contracting in a dish and multiplying in large numbers. This new method could offer a better model for studying muscle diseases, such as muscular dystrophy, and for testing out potential treatment options.

Protein Prompts Healthy Egg-sperm Union in Mice

July 31, 2015 10:33 am | by Elizabeth Doughman, Editor-in-Chief | News | Comments

The protein RGS2 is vital for healthy egg-sperm union in mice, according to a new study from researchers at the National Institutes of Health (NIH). The protein is able to delay egg development in order to allow time for sperm to arrive and fertilization to occur.

Immune Cells Located in Skin Prevent and Defend Against Parasite Infections

July 31, 2015 10:32 am | by Elizabeth Doughman, Editor-in-Chief | News | Comments

After infection with leishmaniasis, the skin retains a population of T cells that remember how to respond and fight previous infections, according to a new study from the University of Pennsylvania School of Veterinary Medicine. This is the first time that a group of T cells have been found to reside in a tissue in response to a parasite infection.

New Pig Model Will Provide Insights into Early Detection, New Treatments of Cancers

July 30, 2015 5:31 pm | News | Comments

With many types of cancers, early detection offers the best hope for survival. However, research into new early-detection screenings, as well as possible interventional radiology and surgical treatments, has been hindered by the lack of a large animal model that would accurately reflect the types of cancers seen in human cells.

Depression Starts as a Gut Feeling

July 30, 2015 9:49 am | by Amanda Boundris, McMaster University | News | Comments

Bacteria in your gut play an important role in inducing anxiety and depression, scientists from the Farncombe Family Digestive Health Research Institute at McMaster University have discovered. Their study, published today in Nature Communications, is the first to explore the role of intestinal microbiota in altered behavior that comes from early life stress.

Where Memory is Encoded and Retrieved

July 30, 2015 9:40 am | News | Comments

Are the same regions and even the same cells of the brain area called hippocampus involved in encoding and retrieving memories or are different areas of this structure engaged? This question has kept neuroscientists busy for a long time. Researchers at the Mercator Research Group "Structure of Memory" at RUB have now found out that the same brain cells exhibit activity in both processes.

Small Genetic Differences Could Mean Life-and-death for Gut Infection

July 29, 2015 10:16 am | News | Comments

Considering how many microorganisms we ingest each day, our gut has an extensive and well-developed immune system. This defense is involved in acute and chronic gut diseases, but it varies dramatically among people. A persistent question is how our genetic make-up affects our gut’s ability to fight infections.
