Table sugar and high-fructose corn syrup are about 50% fructose and these ingredients have become increasingly common in many foods and beverages. Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats. This is [...]
Researchers in Sweden are compiling a remarkable “atlas” that pinpoints the location of thousands of individual proteins in the body’s tissues and cells which will give scientists important insights into the function of different proteins and how changes in the distribution of proteins could be reflected in diseases such as cancer.

Imaging study follows on previous lesion studies to pinpoint regions of brain involved in risk management: finds that individuals’ response to risk and reward can be gauged from activity in two distinct brain regions.
A single molecule in the intestinal wall, activated by the waste products from gut bacteria, plays a large role in controlling whether the host animals are lean or fatty, a research team has found in a mouse study.

Therapeutic strategies to strengthen antioxidant defenses could help to prevent the progression of Huntington’s Disease. New research shows that oxidative stress and damage to certain macromolecules are involved in the progression of Huntington’s Disease (HD), which is characterised by psychiatric and cognitive disturbance, involuntary movements (chorea) and dementia.

UC Berkeley’s resurvey of animal populations in California’s eastern mountains kicked off in 2003 with a resurvey of Yosemite National Park, following the route of Joseph Grinnell in 1914-20. The first results show that small mammals have moved to higher elevations as a result of warming, some expanding their range upward, others moving upward and [...]
A recently introduced polio vaccine is four times more effective at protecting children than previous vaccines and has the potential to eradicate type 1 polio in Nigeria if it reaches enough children, according to a study in the New England Journal of Medicine.
