High in the arid White Mountains of eastern California stand the gnarled, twisted trunks of ancient bristlecone pines. These slow-growing trees quietly weather the ages; at more than 4,000 years old, some are more ancient than the Great Pyramid of Giza. High in the arid White Mountains of eastern California stand the gnarled, twisted trunks of…

In spring 2021, during the height of the COVID-19 pandemic, one of Germany’s 16 federal states instituted an ad ban, forcing retailers to stop all print advertising in that state for three weeks. The state did so under the assumption that such a ban would limit contacts during the pandemic. However, banning print advertising is…

Waterhemp is a nuisance for any crop producer, but in snap bean fields, the weed’s stem segments can break off during harvest, contaminating the crop with inedible look-alike “pods.” However, snap bean is harmed by many of the herbicides registered for waterhemp, leaving producers with few chemical solutions. Waterhemp is a nuisance for any crop producer,…
A complex interplay of energetics and dynamics governs the behavior of nanocrystals in solution. These dynamics are usually interpreted in terms of the theory developed by Derjaguin, Landau, Verwey, and Overbeek (DVLO), and understanding these forces is particularly important for controlling oriented attachment (OA), where individual nanocrystals fuse together in specific alignments. A complex interplay of…
For the first time, NASA data about nitrogen dioxide (NO2), a harmful air pollutant, is available on the Environmental Protection Agency’s (EPA) widely used Environmental Justice Screening and Mapping Tool (EJScreen). This update marks a crucial step in addressing air quality disparities in overburdened communities across the United States. For the first time, NASA data about…

New research from the University of Oxford, published in the journal Carbon Management, makes the case for a novel Carbon Removal Budget to help tackle climate change. It would sit alongside the Carbon Budget that governs how much CO2 can safely be emitted globally. New research from the University of Oxford, published in the journal Carbon…
Atoms are complex quantum systems consisting of a positively charged nucleus surrounded by negatively charged electrons. When multiple atoms come together to form a molecule, the electrons of the constituent atoms interact in a complicated manner, making the computer simulation of molecules one of the hardest problems in modern science. Atoms are complex quantum systems consisting…
