The World Health Organization (WHO) on Monday warned of a multi-drug resistant tuberculosis or MDR-TB. It said that a majority of the world's population are vulnerable to the new strain.

The Manila, Philippines-based WHO told reporters that MDR-TB can cross borders and that an "uncontrolled local epidemic" can threaten the stability of health security across the globe

First time parents should think twice about owning a cat if they have relatives with eczema, a skin disease, a new study finds. A gene mutation and exposure to cats at birth may increase a child's risk of developing eczema during their first year, researchers from the UK and Denmark say.

Other than environmental causes, eczema runs in families and is linked to functional faults in the gene that produces filaggrin (FLG), a protective protein in the skin. Having the mutant FLG gene increased the risk of eczema in a baby's first year twofold. Adding exposure to a cat quadrupled that risk, researchers say

Researchers have achieved a breakthrough in curing broken bones from adult stem cell transplants that could eventually serve as a new treatment for fractures that fail to heal.

A study conducted at the University of North Carolina at Chapel Hill has shown that transplantation of adult stem cells can improve healing by 10 to 20 percent of fractures that might otherwise be hard to repair because of a deficiency in adult stem cells, which normally become reparative cells in response to damage

A University of Adelaide researcher is embarking on a project that could help solve iron deficiency-the world's biggest nutritional deficiency problem.

According to a statement from the university, Dr. Alex Johnson has been awarded funds to work with the Bill Gates-funded HarvestPlus Challenge program. His research looks to increase the iron content in rice and other grains

Giving your infants too much iron which they do not need may delay their development, a study has found.

The study, led by Dr. Betsy Lozoff, University of Michigan research professor at the Centre for Human Growth and Development, leads a debate on the desirable level of iron supplements
