Image Source: [3] belowTopics: Diversity, Diversity in Science, Economy, Women in Science, Science, Research, STEMMost STEM (science, technology, engineering, or math) fields are dominated by men. That makes these fields an excellent career choice for women!STEM Careers Just Right for Many WomenMen outnumber women in most STEM careers. For example, just 17 percent of chemical engineers and 22 percent of environmental scientists are women. But that doesn't mean it's hard for women to get jobs in […]

10:59 AM | Peering into how nanoparticle electrodes in rechargeable lithium-ion batteries work
Nanoparticle electrodes in lithium-ion batteries have both near-surface and interior contributions to their redox capacity, each with distinct rate capabilities. Using combined electron microscopy, synchrotron X-ray methods and ab initio calculations, scientists have investigated the lithiation pathways that occur in NiO electrodes.

8:29 AM | Fast molecular cargo transport by diffusion
In new work, researchers have utilized diffusion as an effective transport mechanism for DNA nanotechnology. These findings contribute a new aspect to be considered for the design of future DNA motors, molecular machines, and nanorobots as they provide a simple way to transport molecules over distances of potentially several 100 nm; which is much faster than when using conventional DNA walkers or motors, which make many small and slow steps.

6:40 PM | Podcast: Manhattan Project Historical Park
In 1997, when Cindy Kelly learned of the impending demolition of the V Site at Los Alamos, the cluster of wooden structures in which the plutonium bomb detonated in the first nuclear test was assembled, she acted quickly. Leaving her position at the Department of Energy in 2000, she founded the Atomic Heritage Foundation to raise awareness and gather partners to preserve the Manhattan Project sites. The partially assembled “Gadget” atop its 100-ft. tower prior to the Trinity […]
