Eliminating air pollution emissions from energy-related activities in the United States would prevent more than 50,000 premature deaths each year and provide more than $600 billion in benefits each year from avoided illness and death, according to a new study by University of Wisconsin–Madison researchers.
Georgia State University scientists have created gene-edited hamsters for studies of social neuroscience and have found that the biology behind social behavior may be more complex than previously thought.
Smithsonian's National Museum of Natural History researcher Murilo Pastana and his colleagues have discovered and described two new species of Amazonian fish—one with striking red-orange fins and the other so small it is technically considered a miniature fish species—in a paper published today, May 16, in the Zoological Journal of the Linnean Society.
Proponents of degrowth have long argued that economic growth is detrimental to the environment. Now, scientists show that curbing growth alone would not make the food system sustainable—but changing what we eat and putting a price on carbon would. In a first, a group led by the Potsdam Institute used a quantitative food and land system model to gauge the effects of degrowth and efficiency proposals on the food sector's greenhouse gas emissions. In their study published in Nature Food, they find that combining a dietary shift, emissions pricing, and international income transfers could make the world's food system emissions-neutral by the end of the 21st century—providing at the same time a healthier nutrition for a growing world population.
Researchers have developed a CRISPR-Cas9 approach to enable gene editing in cockroaches, according to a study published by Cell Press on May 16th in the journal Cell Reports Methods. The simple and efficient technique, named "direct parental" CRISPR (DIPA-CRISPR), involves the injection of materials into female adults where eggs are developing rather than into the embryos themselves.
New chemistry "forensics" indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe.
