- 016.5 million Americans live in landslide hazard zones, study finds
New research has found that 6.5 million Americans live in homes on or near landslide-prone slopes. With a single map, local governments and residents can now see landslide hazard hotspots at the regional, state and county levels to ensure they are aware of and prepared for an emergency.

Female sweat bees need to make a pivotal life decision: remain in the nest to help their mother raise more offspring or leave to establish nests of their own. New research from the Smithsonian Tropical Research Institute (STRI) found that queen pheromones help influence that choice, offering new insight into how cooperation evolved in insect societies.

Carbon capture and storage (CCS) is regaining prominence in climate policy debates in Germany. A study published in Environmental Politics examines the reasons behind this comeback and shows that the strict limits originally envisaged for CCS were progressively relaxed throughout the political process. This increases the risk that the lifespan of fossil fuel infrastructure will be prolonged, potentially sidelining other climate protection measures.

For decades, a theory in physics has postulated the existence of a mirror world whose interaction with our own reality is extremely feeble. The particles in this mirror universe are also thought to be candidates for dark matter. Researchers at the Paul Scherrer Institute PSI have now examined some 25 billion neutrons—thereby ruling out, with a very high degree of certainty, their disappearance into the mirror world. The research is published in the journal Physical Review Letters.

Over time, heavy water extraction has contributed to changes in the aquifer systems under the San Joaquin and Sacramento valleys. Although some of these changes can be reversed, a new study, published in the Proceedings of the National Academy of Sciences, indicates that large part
