| Identical twins reveal mechanisms behind aging Posted: 02 Feb 2012 12:11 PM PST Researchers compared the DNA of identical twins at different ages. They showed that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost, are more common in older people. The results may in part explain why the immune system is impaired with age.  |
| Early bone growth linked to bone density in later life Posted: 02 Feb 2012 12:10 PM PST Researchers have shown that growth in early childhood can affect bone density in adult life, which could lead to an increased risk of developing bone diseases like Osteoporosis. The study is part of ongoing work in assessing the causes of common diseases at different stages of life from before conception through to old age, and the ways in which environmental influences affect gene expression to produce disease.  |
| Treasure trove of wildlife found in Peru park Posted: 02 Feb 2012 12:08 PM PST The Wildlife Conservation Society's (WCS) Peru program recently announced the discovery of 365 species previously undocumented in Bahuaja Sonene National Park in southeastern Peru.  |
| Zap of cold plasma reduces harmful bacteria on raw chicken Posted: 02 Feb 2012 12:07 PM PST A new study demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry.  |
