Cars on the road today are 99% cleaner than they were in 1970. Air quality in the United States is much, much better as a result. In Los Angeles, where I live, lead levels in the air were 50 times higher in the 1970s than today, and the amount of lead in kids' blood has
The stockpile of German ammunition left in Norway in 1945 could have been cleared and dismantled by the Germans. Norway declined the offer and began dumping it in Lake Mjøsa and other lakes instead.
New Minnesota Carlson research debunks the idea that introverts are better listeners than extroverts. In fact, extroverts may have a slight perceived advantage as listeners. The study authors suggest moving past personality-based assumptions to develop listening as a skill.
There is a closing 20-year window in which decisions on climate and land use will determine the fate of dozens of native birds, butterflies and plants across Great Britain, which is already one of the most nature-depleted countries globally. That is the warning in a new study
Climate change is a threat to countries' macroeconomic and fiscal stability. Extreme weather events exacerbated by global warming alone are costing the world $143 billion every year. However, measures to mitigate and adapt to climate change can also pose a risk to fiscal
We are what we eat. And in the ocean, most life-forms source their food from phytoplankton. These microscopic, plant-like algae are the primary food source for krill, sea snails, some small fish, and jellyfish, which in turn feed larger marine animals that are prey for the
Politics are rife with emotions. But new research from the University of Georgia suggests emotions alone may not determine whether people are satisfied with democracy.
The discovery of a 2,400-year-old metalworking workshop in Senegal provides new insights into the history of iron production in Africa. Despite decades of archaeological research, the origins of iron metallurgy in sub-Saharan Africa remain largely unclear. Yet this
Students across education levels have a blind spot for identifying situations that might bring their academic integrity into questionable territory, a study finds. When navigating questions on citation, collaboration, and data collection, students in higher education struggle
These guidelines reinforce the importance of whole grains and fruit and vegetables but clash with the government’s latest nutrition advice on red meat
Deep below the surface of Murujuga, soil expands and contracts from the passage of water. Each wetting cycle is like a sodden breath from lungs holding fragments of stone and shell. Stone artifacts from millennia of Aboriginal life are pushed up slowly, maybe only a few
