Neanderthals have long been painted as meat-eating machines. But could a new look at a dietary proxy and how it changes when meat rots uncover insights into what these extinct hominids really ate?

Human Activities Create Corridors of Change in Aquatic Zones
Canals, dammed reservoirs, irrigation ditches, and pollution are changing species diversity, microbial communities, and nutrient levels in aquatic zones across the planet.
Piecing Together the Big Picture on Water and Climate
A new database brings together water isotope data from many sources, providing an integrated resource for studying changes in Earth’s hydroclimate over the past 2,000 years.
Antarctic Microbes Shape Nutrient Content of Snowmelt
As temperatures continue to rise, snow-dwelling microbes could accelerate melting and influence downstream ecosystems.
Assessing a New Clue to How Much Carbon Plants Take Up
Current climate models disagree on how much carbon dioxide land ecosystems take up for photosynthesis. Tracking the stronger carbonyl sulfide signal could help.
Mushrooms Could Provide a Record of Grassland History
Scientists measured carbon isotopes in certain types of fungi to assess whether the organisms can track how climate change is affecting grasses.
EPA Head Calls Climate Change Biggest Threat to U.S. Progress
McCarthy says that despite anxiety at the agency about the election results, she is confident in EPA’s work and that efforts to control climate change will continue.
Glacial Meltwater Features Depend on Glacier Type and Location
With climate change, some glaciers will melt faster than others, altering the proportions of nutrients in meltwater and changing downstream ecosystems.
