Global wildlife populations: 58 percent decline, driven by food and energy demand

Thu, 27/10/2016 - 3:33pm
Global populations of vertebrates -- mammals, birds, reptiles, amphibians, and fish -- have declined by 58 percent between 1970 and 2012, states a new report. Animals living in the world's lakes, rivers, and freshwater systems have experienced the most dramatic population declines, at 81 percent. Because of human activity, the report states that without immediate intervention global wildlife populations could drop two-thirds by 2020.

Is more, better? Finding the balance between nutritional supplements and eye health

Thu, 27/10/2016 - 1:46pm
In the past decade, ophthalmologists have been prescribing nutritional supplements to be taken daily to prevent or slow vision loss from age-related macular degeneration (AMD). Now, using nutritional supplements for eye health has become more common. But does increasing the recommended dose increase your protection? A case report reveals what can happen when a patient takes more of a supplement than their body needs.

'Neighbour maps' reveal the genome's 3D shape

Thu, 27/10/2016 - 1:35pm
A three-dimensional computer model of the human genome has been created by researchers. The shape of DNA (as well as its sequence) significantly affects biological processes and is therefore crucial for understanding its function. This new study has provided a first three-dimensional, approximate but realistic, identikit of the human genome. Thanks to the characteristics of the new method, the structural reconstruction based on both experimental information and statistical methods will be refined as new experimental data become available.
