Lallemand is pleased to announce that the European Food Safety Authority (EFSA) has issued a positive opinion on the use of Vitamin D2 rich baker's yeast (Saccharomyces Cerevisiae) in yeast-leavened bread, rolls, fine bakery wares and food ...
Swiss scientists have uncovered the mechanism by which novel, revolutionary solar cells based on lead iodide perovskite light-absorbing semiconductor transfer electrons along their surface. The finding shows these devices constitute a new ...

Exposing skin to sunlight may help to reduce blood pressure and thus cut the risk of heart attack and stroke, a study published in the Journal of Investigative Dermatology suggests. Research carried out at the Universities of Southampton ...
Humans cannot hope to survive life on Mars without plenty of protection from the surface radiation, freezing night temperatures and dust storms on the red planet. So they could be excused for marveling at humble Antarctic lichen that has ...

People suffering from the chronic pain of fibromyalgia might benefit from taking vitamin D supplements if they suffer from low levels of the vitamin, a new study from Austria suggests. There's no cure for fibromyalgia, which can lead to ...
This week a new study published in Nature and co-authored by Drs. Chris Moore and Daniel Obrist of Nevada's Desert Research Institute establishes, for the first time, a link between Arctic sea ice dynamics and the region's changing ...
