Research has proved the significance of forests in controlling carbon emissions, however, our research sheds light on the management of existing forests to combat climate change. To examine the role o...
Drought stress commonly happens more than once during the life cycle of perennial trees. Stress memory endows better capacity to cope with repeated stresses for plants, while the underlying mechanisms...
The impact of climate extremes on forest ecosystems is poorly understood but important for predicting carbon and water cycle feedbacks to climate. Some knowledge gaps still remain regarding how drough...
The discovery of the Higgs boson at CERN’s Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently inv...
This paper develops a theory to illustrate the relationship between the profitability of firms producing along the value chain and the sequential production stages. Using a bilateral monopoly framewor...
Trust between parties should drive contract design: if parties were suspicious about each others' reaction to unplanned events, they might agree to pay higher costs of negotiation ex ante to complete ...

Evidence from an ancient eggshell has revealed important new information about the extreme climate change faced by human early ancestors.
The first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted ...
A new study led by U.S. National Science Foundation-funded paleontologists at the University of Washington and its Burke Museum of Natural History & Culture indicates that the earliest ...
Hibernation is a familiar feature on Earth today. Many animals -- especially those that live close to or in polar regions -- hibernate to get through tough winter months when food is scarce, temperatu...
