Some Stress in early Life extends Lifespan

University of Michigan researchers have discovered that oxidative stress experienced early in life increases subsequent stress resistance later in life. Oxidative stress happens when cells produce more oxidants and free radicals than they can deal with. It’s part of the aging process, but can also arise from stressful conditions such as exercise and calorie restriction.

Examining a type of roundworm called C. elegans, U-M scientists Ursula Jakob and Daphne Bazopoulou found that worms that produced more oxidants during development lived longer than worms that produced fewer oxidants. Their results are published in the journal Nature.

Scientists discover new protection against oxidative stress. Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanovi-Burmazovi from the Chair of Bioinorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with researchers from the USA, have discovered that zinc can activate an organic molecule, helping to protect against oxidative stress.

Zinc is a trace mineral we need in order to remain healthy. FAU researchers working together with Prof. Dr...

Mushrooms are Full of Antioxidants that may have Antiaging potential

Mushrooms may contain unusually high amounts of two antioxidants that some scientists suggest could help fight aging and bolster health, according to a team of Penn State researchers. In a study, researchers found that mushrooms have high amounts of the ergothioneine and glutathione, both important antioxidants, said Robert Beelman, professor emeritus of food science and director of the Penn State Center for Plant and Mushroom Products for Health. He added that the researchers also found that the amounts the two compounds varied greatly between mushroom species. “What we found is that, without a doubt, mushrooms are highest dietary source of these two antioxidants taken together, and that some types are really packed with both of them,” said Beelman...

In-car air study of commuting cars finds dangers to human health. The first in-car measurements of exposure to pollutants that cause oxidative stress during rush hour commutes has turned up potentially alarming results. The levels of some forms of harmful particulate matter inside car cabins was found to be twice as high as previously believed. Most traffic pollution sensors are placed on the ground alongside the road and take continuous samples for a 24-hour period...
