Stunning blue waters surround and pass through the tidal channels of islands in the Bahamas. Small tidal changes on the banks cause water to flow through the narrow channels between the islands, first in one direction and then the other. The darker blue sections of water are the deepest parts of the channels and the surrounding light blue color is more shallow (less than 25 meters / 80 feet).

This is the view that you get from the terrace bar at the SkyLounge in the Hilton hotel in Tower Hill. They were nice enough to let me come by and set up my tripod at sunset and capture the evening view. I got the pink haze at the top of the frame as the sunlight reflected off the horizon.

When doctors hurl toxic death at cancer cells, often a few will survive and come back. A family of enzymes called KDM5 histone demethylases is emerging as important for this resilience and drugs that inhibit KDM5 enzymes could be active in treating several types of cancer. A team of investigators obtained detailed structural information, showing how inhibitors of the KDM5 family interact with their targets by building a molecular model of the KDM5A enzyme, along with an inhibitor bound in the active site. Their findings could inform efforts to design more potent and selective anticancer drugs.

This is the first image ever captured of blue jet lightning. It was taken at Arecibo Observatory in Chile. A team of researchers at Arecibo captured video evidence from the ground of this lightning phenomenon known as blue jet. The discovery is the first ground-based evidence linking the ionosphere with cloud tops in blue jet events. According to Victor Pasko of Penn State University, an electrical engineer working at Arecibo, pilots and others reported observations of red sprites and blue jets long before the first one was captured on video, and numerous undocumented reports of similar phenomena have appeared in scientific literature for over a century.
