Researchers discover new mechanism behind resistance to cancer treatment
Developing resistance to chemotherapy is a nearly universal consequence for cancer patients with solid tumors -- such as those of the breast, prostate, lung and colon -- that have metastasized, or spread, throughout the body.

Sequencing of malaria genomes reveals challenges, opportunities in battle against parasite
Genetic variability revealed in malaria genomes newly sequenced by two multi-national research teams points to new challenges in efforts to eradicate the parasite, but also offers a better picture of its genetic composition, providing an initial roadmap in the development of vaccines to combat malaria.

Heart muscle cell grafts suppress arrhythmias after heart attacks in animal study
Researchers have made a major advance in efforts to regenerate damaged hearts.

White blood cells mediate insulin resistance
Researchers at the University of California, San Diego School of Medicine say neutrophils, an abundant type of white blood cell typically tasked with attacking bacteria and other foreign invaders, also plays an unexpected role in mediating insulin resistance -- the central characteristic of type 2 diabetes, which afflicts an estimated 26 million Americans.
