Results from this study bring new light to elephants’ individuality, said Associate Professor George Wittemyer. Credit: Guillaume Bastille-Rousseau/Colorado State University More Wild African elephants, known for their intelligence, show markedly different movements and reactions to the same risks and resources. A new study led by Colorado State University and Save the Elephants reveals the magnitude

Reaction stages when a psoralen molecule binds to DNA. The result is that the psoralen is permanently bound to the DNA via a cyclobutane ring. The cell is altered and thus damaged, and triggers the process of programmed cell death. Credit: ACS/Janina Diekmann More The term “PUVA’ stands for ‘psoralen’ and ‘UV-A radiation.’ Psoralens are

Juvenile green sturgeon in the Sacramento River have done poorly in years with high discharges of cold water from Shasta Lake. Credit: U.S. Fish and Wildlife Service More Cold water released from Lake Shasta into the Sacramento River to benefit endangered salmon can be detrimental to young green sturgeon, a threatened species adapted to warmer

David Cicimurri, curator of the South Carolina State Museum’s natural history collection, worked with James Knight, of the University of South Carolina Aiken Department of Biology and Geology. The two

Credit: University of Liverpool Researchers at the University of Liverpool are leading a new international project to investigate the curious phenomenon of ‘male-killing’ microbes in insects. Many insect species carry microbes within their reproductive cells. Importantly, these microbes can only be passed down to offspring through the maternal line. Males are therefore seen as a

Figure 1-1 Graphical summary of the work. Carbon nanotubes with platinum (Pt) decoration shows high affinity with liquid metals (left), and it results in the uniform dispersion of carbon nanotubes in liquid metal, forming stretchable metal composite (middle). The stretchable metal composite has superior mechanical properties than pristine liquid metal, and thus fits to be

A team of researchers examined an ancient papyrus with a supposed empty spot. With the help of several methods, they discovered which signs once stood in this place and which ink was used. Credit: HZB Researchers from the Egyptian Museum and Papyrus Collection, Berlin universities and Helmholtz-Zentrum Berlin studied a small piece of papyrus that
