UD researchers report new discovery in ‘Science’ about manganese in aquatic environments

An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers that was published this week in Science.

The discovery alters understanding of the chemistry that moves manganese and other elements, like oxygen and carbon, through the natural world. Manganese is an essential nutrient for most organisms and helps plants produce oxygen during photosynthesis. (more…)

Winning margins in the Tour de France can be tight. In 2010 just 39 seconds separated the top two after more than 90 hours in the saddle. When every second counts, riders do all they can to gain competitive advantage, from aerodynamic carbon fibre bikes to the latest sports nutrition.

Now there could be a new, completely legal and rather surprising weapon for riders aiming to shave vital seconds off their time – beetroot juice. (more…)

Biodiversity improves water quality in streams through a division of labor

ANN ARBOR, Mich.— Biologically diverse streams are better at cleaning up pollutants than less rich waterways, and a University of Michigan ecologist says he has uncovered the long-sought mechanism that explains why this is so.

Bradley Cardinale used 150 miniature model streams, which use recirculating water in flumes to mimic the variety of flow conditions found in natural streams. He grew between one and eight species of algae in each of the mini-streams, then measured each algae community’s ability to soak up nitrate, a nitrogen compound that is a nutrient pollutant of global concern.

New research into the health benefits of beetroot juice suggests it’s not only athletes who can benefit from its performance enhancing properties – its physiological effects could help the elderly or people with heart or lung-conditions enjoy more active lives.

Beetroot juice has been one of the biggest stories in sports science over the past year after researchers at the University of Exeter found it enables people to exercise for up to 16% longer. (more…)
