Researchers find positive legacy effects after grassland droughts

A four-year experiment combined with a 40-year observation in Inner Mongolia found that previous-year extreme droughts can create strong positive legacies for current-year community productivity. The mechanism driving this effect is the coupled increase of annuals and an early less, middle more precipitation pattern.

Catch a break: Higher vitamin K intake linked to lower bone fracture risk late in life

A long-term study found that eating more than 100 micrograms of vitamin K1 daily reduced the risk of fractures and hospitalizations by 31-49%. Dark leafy vegetables and one-to-two serves of vegetables are recommended for optimal benefits. Vitamin K1 has been shown to enhance cardiovascular health and promote bone health.
