Stones with web-shaped patterns found at ancient site in Denmark
A few ancient stones with a spider web pattern on them have been found among hundreds depicting the sun on an island in Denmark, raising questions about the sun-worshiping people who lived there 5,000 years ago. In addition, archaeologists were surprised to find a piece of copper at the site since the community was not believed to have had access to metals at that time.

Study compares genomes of termites, cockroaches
Researchers have compared the genomes of German cockroaches and drywood termites, looking for information about how sociality evolved in the creatures. The study, published in Nature Ecology & Evolution, charts the evolutionary changes that took place to make the lifestyles of termites and cockroaches so different, even though termites sprang from cockroaches around 150 million years ago.

Flattie spiders use super-fast spin to capture prey
Flattie spiders can quickly grab prey with their super-fast spin, the fastest such maneuver by any land animal, and researchers have captured the move on slow-motion cameras. The spiders pivot on the leg closest to their prey, moving rapidly to lunge at the prey mouth first, according to findings published in the Journal of Experimental Biology.

Scientists using gene editing to stop HIV from infecting cells
Numerous studies are underway to determine how gene therapy and the use of gene-editing tools can possibly cure HIV by using altered cells to decimate the virus and reduce the number of cells in reservoirs where HIV stays hidden in a dormant state. One such study is being conducted by Dr. John Zaia of City of Hope research center in California, which tweaks blood stem cells to disable a gene to allow the cells to resist HIV.
