Archaeologists discover bread that predates agriculture by 4,000 years

At an archaeological site in northeastern Jordan, researchers have discovered the charred remains of a flatbread baked by hunter-gatherers 14,400 years ago. It is the oldest direct evidence of bread found to date, predating the advent of agriculture by at least 4,000 years. The findings suggest that bread production based on wild cereals may have …

CLIMATE CHANGE IS MAKING NIGHT-SHINING CLOUDS MORE VISIBLE

Increased water vapor in Earth’s atmosphere due to human activities is making shimmering high-altitude clouds more visible, a new study finds. The results suggest these strange but increasingly common clouds seen only on summer nights are an indicator of human-caused climate change, according to the study’s authors. Noctilucent, or night-shining, clouds are the highest clouds …

Previously unsuspected volcanic activity confirmed under West Antarctic Ice Sheet [WAIS]at Pine Island Glacier

Tracing a chemical signature of helium in seawater, an international team of scientists funded by the National Science Foundation (NSF) and the United Kingdom’s (U.K.) Natural Environment Research Council (NERC) has discovered a previously unknown volcanic hotspot beneath the massive West Antarctic Ice Sheet (WAIS). Researchers say the newly discovered heat source could contribute in …

ASU professor says Kilauea volcano began eruption 35 years ago!

Hawaii’s Big Island has been under siege for the last two weeks due to violent activity from the Kilauea volcano, which has produced haunting images: spewing ash and toxic gases, lava pouring through the streets and people fleeing their homes. And Kilauea is showing no signs of slowing down. Scientists are warning residents to brace themselves for …

Coldest Place On Earth Is Colder Than Scientist Thought !

Tiny valleys near the top of Antarctica’s ice sheet reach temperatures of nearly minus 100 degrees Celsius (minus 148 degrees Fahrenheit) in the winter, a new study finds. The results could change scientists’ understanding of just how low temperatures can get at Earth’s surface, according to the researchers. Scientists announced in 2013 they had found the …

800 Million Tons of Blue Carbon Lie Buried in U.S. Tidal Wetlands

Tidal wetlands in the contiguous U.S. can store roughly 800 million tons of carbon in their soils. That is the latest estimate from a team of over 30 scientists from across the U.S., published June 21 in Scientific Reports and led by the Smithsonian Environmental Research Center. But even more surprising to the authors: As far as …
