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.

New study helps predict impact of ocean acidification on shellfish
An international study to understand and predict the likely impact of ocean acidification on shellfish and other marine organisms living in seas from the tropics to the poles is published this week in the journal Global Change Biology.

New technology eliminates plant toxins
A team of researchers from the University of Copenhagen have developed a method to hinder unwanted toxins from entering the edible parts of plants such as the oilseed rape, which will make it suitable for animal feed.

New study finds link between cell division and growth rate

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. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
