Scientists have discovered a new gene mechanism that appears to regulate triglyceride levels and may protect carriers of a gene variant against cardiovascular disease, especially among those with greater intakes of polyunsaturated fat (PUFA).  


Al exercise is good exercise and there is a 100 percent chance you will lose weight if you consume fewer calories than you burn, but if you are interested in optimizing fat and weight loss after the holidays, aerobic training is the best way to go, according to Duke researchers.

They compared aerobic training, resistance training, and a combination of the two in what they say is the largest randomized trial to analyze changes in body composition from the three modes of exercise in overweight or obese adults without diabetes.


Soil organic matter makes up the bulk of terrestrially bound carbon in our biosphere. Those compounds play an important role, not only for soil fertility and agricultural yields but also for controlling the concentration of carbon dioxide in the atmosphere.

Climatic change can therefore be slowed down or accelerated according to our management of soil resources. A new study sheds some light on the process.


A project has identified the mechanism responsible for generating our fingers and toes, and revealed the importance of gene regulation in the transition of fins to limbs during evolution.  

Their conclusion involves a theoretical model for pattern formation known as the Turing mechanism. In 1952, mathematician Alan Turing proposed equations for pattern formation, which describe how two uniformly-distributed substances, an activator and a repressor, trigger the formation of complex shapes and structures from initially-equivalent cells. 


A recent Finnish analysis determined that approximately ten percent of 6-8 year olds have sleep-disordered breathing, increased among children with enlarged tonsils, crossbite and convex facial profile. Unlike in adults, excess body fat is not associated with sleep-disordered breathing in this age group. The study was part of the Physical Activity and Nutrition in Children (PANIC) Study led by the Institute of Biomedicine at the University of Eastern Finland. 


A new hypothetical material offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics.


Yes, theoretical materials. It must be the weekend.

Rice University theoretical physicist Boris Yakobson and postdoctoral fellow Xiaolong Zou were investigating the atomic-scale properties of two-dimensional materials - we all have those laying around the house to build Christmas gifts - when they concluded that a particular formation, a grain boundary in metal disulfides, will create a metallic, and therefore conducting, path only a fraction of a nanometer wide. 

That's basically the width of a chain of atoms.
