A common chemotherapy drug has been successfully delivered to cancer cells inside tiny microparticles using a method inspired by our knowledge of how the human immune system works. The drug, delivered in this way, reduced ovarian cancer tumours in an animal model by 65 times more than using the standard method. This approach is now being developed for clinical use.

ANN ARBOR, Mich.---People who give, live longer, studies have shown. Now, a new study shows that why people volunteer---not whether they volunteer---is what really counts.

People who volunteer because they want to help others, live longer than people who don't volunteer at all, University of Michigan researchers found. But those who volunteer mainly for some sort of personal benefit live no longer than non-volunteers, on average.

A new analysis has found that women who develop certain hereditary cancers develop them at earlier ages than women in the previous generation. Published early online in CANCER, the results point to the importance of tracking younger ages of cancer diagnosis to determine when to provide counseling, screening, and treatment services.

Houston, TX – Women with a deleterious gene mutation are diagnosed with breast cancer almost eight years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas MD Anderson Cancer Center.

ROCHESTER, Minn. -- Mayo Clinic researchers have developed a genome-based immunization strategy to fight feline AIDS and illuminate ways to combat human HIV/AIDS and other diseases. The goal is to create cats with intrinsic immunity to the feline AIDS virus. The findings -- called fascinating and landmark by one reviewer -- appear in the current online issue of Nature Methods.

MADISON – Ever since human induced pluripotent stem cells were first derived in 2007, scientists have wondered whether they were functionally equivalent to embryonic stem cells, which are sourced in early-stage embryos.

Both cell types have the ability to differentiate into any cell in the body, but their origins – in embryonic and adult tissue – suggest that they are not identical.

A new, open-access article (DOI: 10.1603/IPM10024) in the Journal of Integrated Pest Management provides a brief summary of the various species of thrips present in U.S. cotton, their plant host range and injury to cotton, a general description of thrips biology, and management practices currently available to growers.
