Resistance to last-line antibiotic makes bacteria resistant to immune system Posted: 20 May 2013 10:12 PM PDT Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a new study. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response.

Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes in their daughters Posted: 20 May 2013 03:54 PM PDT Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes, in their daughters.

How bilinguals switch between languages Posted: 20 May 2013 01:38 PM PDT Individuals who learn two languages at an early age seem to switch back and forth between separate "sound systems" for each language, according to new research. The research addresses enduring questions in bilingual studies about how bilingual speakers hear and process sound in two different languages.

Do salamanders' immune systems hold the key to regeneration? Posted: 20 May 2013 01:37 PM PDT Salamanders' immune systems are key to their remarkable ability to regrow limbs, and could also underpin their ability to regenerate spinal cords, brain tissue and even parts of their hearts, scientists have found. In new research, scientists have found that when immune cells known as macrophages were systemically removed, salamanders lost their ability to regenerate a limb and instead formed scar tissue.

New source of kidneys for transplant suggested Posted: 20 May 2013 01:36 PM PDT Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs?

Gym class reduces probability of obesity, study finds for first time Posted: 20 May 2013 01:36 PM PDT Little is known about the effect of physical education on child weight, but a new study finds that increasing the amount of time that elementary schoolchildren spent in gym class reduces the probability of obesity.

Timing of cancer radiation therapy may minimize hair loss Posted: 20 May 2013 01:36 PM PDT Discovering that mouse hair has a circadian clock - a 24-hour cycle of growth followed by restorative repair - researchers suspect that hair loss in humans from toxic cancer radiotherapy and chemotherapy might be minimized if these treatments are given late in the day.

Immune protein could stop diabetes in its tracks, discovery suggests Posted: 20 May 2013 07:49 AM PDT Researchers have identified an immune protein that has the potential to stop or reverse the development of type 1 diabetes in its early stages, before insulin-producing cells have been destroyed. The discovery has wider repercussions, as the protein is responsible for protecting the body against excessive immune responses, and could be used to treat, or even prevent, other immune disorders such as multiple sclerosis and rheumatoid arthritis.
