Isotopic evidence reveals surprising dietary practices of ancient hunter-gatherers
It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the diet.....»»

US’s power grid continues to lower emissions—everything else, not so much
Excluding one pandemic year, emissions are lower than they've been since the 1980s. Enlarge (credit: US EIA) On Thursday, the US Department of Energy released its preliminary estimate for the nation's carbon emissions in.....»»
Umami-rich scrap fish and invasive species can liven up vegetables, says gastrophysicist
Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to "boring" vegetables. University of Copenhagen gastrophysicist Ole G. Mouritsen puts mathematical equa.....»»
New rock art discoveries in Eastern Sudan tell a tale of ancient cattle, the "green Sahara" and climate catastrophe
The hyper-arid desert of Eastern Sudan, the Atbai Desert, seems like an unlikely place to find evidence of ancient cattle herders. But in this dry environment, my new research has found rock art over 4,000 years old that depicts cattle......»»

Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»

Researchers discover mechanism regulating bud dormancy release in tree peony
In perennial woody plants, bud endodormancy is crucial for survival under adverse environmental conditions in winter, such as low temperature (LT) and dehydration stress. To break bud dormancy is essential for the resumption of bud growth and floweri.....»»
SlTHM27-SlGAD2 model regulates the cold tolerance in tomato by regulating GABA and anthocyanin

Artificial intelligence helps scientists engineer plants to fight climate change
The Intergovernmental Panel on Climate Change (IPCC) has declared that removing carbon from the atmosphere is now essential to fighting climate change and limiting global temperature rise. To support these efforts, Salk Institute scientists are harne.....»»
Can climate change accelerate transmission of malaria? New research sheds light on impacts of temperature
Malaria is a mosquito-borne disease caused by a parasite that spreads from bites of infected female Anopheles mosquitoes. If left untreated in humans, malaria can cause severe symptoms, health complications and even death......»»
Evolutionary biologists show that the color variants of female cuckoos are based on ancient mutations
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of female cuckoos: a gray morp.....»»
