Mammals and their relatives thrived, diversified during so-called ‘Age of Dinosaurs,’ researchers show
Old myths state that, during the time of the dinosaurs, mammals and their relatives were small and primitive. But new research shows that, during the time of the dinosaurs, mammals and their relatives actually underwent two large ecological radiations, diversifying into climbing, gliding and burrowing forms with a variety of diets.

Abundance of gases in Enceladus’s ocean are a potential fuel — if life is there to consume it
The subsurface ocean of Saturn’s moon Enceladus probably has higher than previously known concentrations of carbon dioxide and hydrogen and a more Earthlike pH level, possibly providing conditions favorable to life, according to new research from planetary scientists at the UW.
Deep submersible dives shed light on rarely explored coral reefs
Just beyond where conventional scuba divers can go is an area of the ocean that still is largely unexplored. In waters this deep — about 100 to at least 500 feet below the surface — little to no light breaks through. Researchers must rely on submersible watercraft or sophisticated diving equipment to be able…

Urgent action on climate change will prevent heat-related deaths in major U.S. cities
The planet will warm by about 3 degrees Celsius (5.4 degrees Fahrenheit) above pre-industrial levels by the end of the century if the U.S. and other nations meet only their current commitments under the Paris climate agreement to reduce emissions of heat-trapping gases. According to a paper by U.S. and U.K. scientists published in Science Advances today, accelerating ambition to reduce global warming emissions to meet the Paris Agreement’s goal of limiting temperature rise to well below 2 degrees Celsius could prevent thousands of extreme heat-related deaths in cities across the U.S.

New study identifies patterns of growth in chronic lymphocytic leukemia
In a paper published May 29 in Nature, scientists report that the growth of chronic lymphocytic leukemia is apt to follow one of three trajectories: relentlessly upward, steadily level or something in between. The particular course the disease takes is tightly linked to the genetic makeup of the cancer cells, particularly the number of growth-spurring “driver” mutations they contain.

Scientists use molecular tethers and chemical ‘light sabers’ to construct platforms for tissue engineering
In a paper published May 20 in the journal Nature Materials, a team of researchers from the University of Washington unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells.
