How golden staph paralyses our immune defences
25 November 2013 When golden staph enters our skin it can identify the key immune cells and 'nuke' our body's immune response. Now we know how, thanks to an international research group led by dermatologists from the Centenary Institute and the University of Sydney. Using state-of-the art microscopy techniques, the team identified the key immune cells that orchestrate the body's defenders against invading golden staph, and also how the bacteria can target and destroy these cells, circumventing the body's immune response.

Steroid injections for premature babies linked to mental health risk
Steroid injections for premature babies linked to mental health risk
Steroid injections given to pregnant women before premature birth may increase the child's risk of later behavioural difficulties, a study has found. Mothers who are expected to give birth prematurely are often given an infusion of glucocorticoids, which mimic the natural hormone cortisol. This treatment is vital for helping the baby's lungs mature, but the new research suggests it may also increase the risk of mental health problems including attention-deficit/hyperactivity disorder (ADHD).

An Inside Look at a MOF in Action
An Inside Look at a MOF in Action
A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first in situ electronic structure observations of the adsorption of carbon dioxide inside Mg-MOF-74, an open metal site MOF that has emerged as one of the most promising strategies for capturing and storing greenhouse gases.

Different gene expression in male and female brains helps explain differences in brain disorders
UCL scientists have shown that there are widespread differences in how genes, the basic building blocks of the human body, are expressed in men and women's brains. Based on post-mortem adult human brain and spinal cord samples from over 100 individuals, scientists at the UCL Institute of Neurology were able to study the expression of every gene in 12 brain regions.

Obesity at age 66 predicts health at 85, study finds
Women entering their senior years with a healthy weight and waist size have a significantly better chance of reaching age 85 without chronic disease or mobility impairment, according to a nationwide health study that followed more than 36,000 women for up to 19 years. Put another way, a 66-year-old woman with a body mass index (BMI) over 30, combined with a waist circumference of about 34 inches, has increased odds of coronary and cerebrovascular disease, diabetes mellitus, certain cancers, hip fractures and arthritis over the subsequent two decades later - if she lives that long.
