Berkeley Lab Receives DOE Support for Building to Study Microbe-Ecosystem Interactions for Energy and Environmental Research
The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) recently received federal approval to proceed with preliminary design work for a state-of-the-art building that would revolutionize investigations into how interactions among microbes, water, soil, and plants shape entire ecosystems.
Adequate Intake of Milk and Dairy Products in Different Life Stages Helps Prevent Chronic Diseases
Ángel Gil, Professor of Biochemistry and Molecular Biology at the University of Granada, has recently coordinated a study reviewing worldwide scientific literature on the role of dairy products in health and in the prevention of chronic diseases (cardiovascular, metabolic syndrome, colon or bladder cancer, and type 2 diabetes).
With Little Training, Machine-Learning Algorithms Can Uncover Hidden Scientific Knowledge
Sure, computers can be used to play grandmaster-level chess, but can they make scientific discoveries?
How Extreme Heat Overwhelms Your Body and Becomes Deadly
The heat wave that scorched Europe last week felt like a red alert of climate change.
Old-Growth Forests May Provide Valuable Biodiversity Refuge in Areas at Risk of Severe Fire
New findings show that old-growth forests, a critical nesting habitat for threatened northern spotted owls, are less likely to experience high-severity fire than young-growth forests during wildfires.
