Low-carb slimming diets may clog arteries and increase the risk of heart attacks and strokes, a study suggests.
Diets based on eating lots of meat, fish and cheese, while restricting carbohydrates have grown in popularity in recent years.
But the Beth Israel Deaconess Medical Center in the US found such habits caused artery damage in tests on mice.
Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes. The research, published today in Nature Methods, opens the door to the hidden world of zinc biology by giving scientists an accurate way of measuring the concentration of zinc and its location in cells for the first time.

In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.
The discovery, described in the August 30 issue of the journal Nature Neuroscience, could offer insight into autism and other disorders where social distance is an issue.
A new method tested in monkeys for replacing mitochondrial DNA could one day prevent devastating diseases.

The American Heart Association today released new recommendations on limiting intake of added dietary sugars.
Back in 2006, the American Heart Association (AHA) recommended minimizing consumption of beverages and foods with added sugars.
Now, the AHA is getting more specific, with recommendations detailed down to the teaspoon based on a person’s age, sex, and activity level.
Researchers have found a genetic link between physical pain and social rejection, which means that breaking up with a partner really can be painful.
Psychologists at the University of California, Los Angeles say the human body has a gene which connects physical pain sensitivity with social pain sensitivity.
The findings back the common theory that rejection ‘hurts’ by showing that a gene regulating the body’s most potent painkillers – mu-opioids – is involved in socially painful experiences too.
