Even though essential oils have been around for centuries, dating back to the early Egyptians and were brought as gifts to Jesus in biblical times (remember frankincense?), they’ve become more relevant today than ever before. While people traditionally see a…
(University of Vienna) The first flowering plants originated more than 140 million years ago in the early Cretaceous. They are the most diverse plant group on Earth with more than 300,000 species. In a new study in Communications Biology, evolutionary biologists around Agnes Dellinger and Jürg Schönenberger from the University of Vienna have analysed 3-dimensional models of flowers and found that flower shapes can evolve in a modular manner in adaptation to distinct pollinators.
Researchers show how plants harness toxic molecules called reactive oxygen species for the signaling pathway that gives rise to roots. Identifying the complex molecular interactions that regulate root growth could lead to more productive crops with roots optimized for different soil types.

Scientists placed honey bee hives next to soybean fields in Iowa and tracked how the bees fared over the growing season. To their surprise, the bees did well for much of the summer. The colonies thrived and gained weight. But in August, the trend reversed. By mid-October, most of the honey was gone and the overwintering brood was malnourished, the team discovered. Placing the hives near restored prairies late in the season rescued them.
Masting is what biologists call the pattern of trees for miles around synchronizing to all produce lots of seeds â or very few. Why and how do they get on schedule?
Researchers have found that the presence of yeasts can alter the chemical composition and thus the nutritional value of nectar for pollinators such as bees. Moreover, the study found that yeasts can even boost bee health and colony fitness.
