New research suggests that statins are associated with lower rates of breast cancer and subsequent mortality. Credit: © designer491 / Fotolia A 14 year study in more than one million people has found that women with high cholesterol have significantly lower rates of breast cancer and improved mortality. The research, presented today at ESC Congress, ... sciencebulletin.org/archive...

Schematic of a new catalyst made of copper nanoparticles that converts carbon dioxide to multicarbon products (ethylene, ethanol, and propanol). At top left are transmission electron microscope images of the copper nanoparticles. The transformation of the nanoparticles from spheres to cube-like structures is key to keeping the energy input low for the reactions. Credit: Dohyung ... sciencebulletin.org/archive...

Clay minerals on Mars may have formed in primordial steam bath
171206132214 1 900x600
Mars may have been enveloped in a thick, steamy atmosphere as the planet’s crust cooled and solidified. That steam bath could have created many of the clay mineral deposits that have long been attributed to water flow on or just beneath the surface.
