MHS: I went in thinking it was an interesting hypothesis that there was a Norse trading post in Baffin Island. First, I performed an initial physical analysis of the material, which included spun sinew, spun yarn, woven textiles, and raw...
Trace metals in the atmosphere have a hefty impact on marine life, according to a new paper. The sources of these aerosol particles include volcanoes, wildfires, and desert dust, and the burning of fossil fuels. After being spewed up and...
New research shows that pathogens that incubate at higher temperatures are more infectious. Yet the computer models that predict the spread of epidemics from climate change—such as crop blights or disease outbreaks—may not be taking into account this important...
Researchers have developed a technique that offers new insight into “cellular memory.” The cells in our body divide constantly throughout life. But how do cells remember whether to develop into a skin, liver, or intestinal cell? It’s a question that...
In the 19th century, the “rain follows the plow” myth was a justification for settling the Great Plains. The cultivation of semi-arid to arid land was said to increase rainfall by moistening the soil and humidifying the atmosphere. Subsequent research...
Even if we achieve the carbon emissions reductions that the Paris Agreement calls for, there is the risk of the planet entering “hothouse Earth” conditions. A “hothouse Earth” climate will in the long term stabilize at a global average of...
Scientists are officially debunking the myth that megalodon sharks still exist. The whale-eating monsters became extinct about 2.6 million years ago. “I was drawn to the study of Carcharocles megalodon’s extinction because it is fundamental to know when species became...
A new study suggests that two sets of dynamics initiate and perpetuate the kinds of leaps of faith firefighters and others in high-risk occupations routinely take: supporting and sustaining. The findings convey what goes into a person’s ability to make critical...
Homo sapiens were able to thrive because they could generalize across different kinds of environments, but then also rapidly specialize upon encountering specifically challenging environments, say researchers. They call this new ecological role the “general specialist.” The Homo sapiens that migrated...
A new predictive model that examines spore-forming bacteria and when they’ll emerge may make the “sell-by” and “best-by” dates on milk cartons more meaningful and accurate, according to research. “Putting dates on milk cartons is a big issue, because consumers...
