Chemists cook up three atom-thick electronic sheets

Making thin films out of semiconducting materials is analogous to how ice grows on a windowpane: When the conditions are just right, the semiconductor grows in flat crystals that slowly fuse together, eventually forming a continuous film. This process of film deposition is common for traditional semiconductors like silicon or gallium arsenide — the basis of modern electronics — but scientists are now pushing the limits for how thin they can go. They have demonstrated a way to create a new kind of semiconductor thin film that retains its electrical properties even when it is just atoms thick. —> Read More

This Is The Next Step In Saving The Planet, According To E.O. Wilson & Sean Carroll

Edward O Wilson made his name by arguing that two apparently disparate things – human society and the natural world – are governed by the same principles. Sean B Carroll made his name by unifying the study of humans and animals, showing that development in both is driven by the same fundamental molecular and genetic processes. So what happened when these two scientists were brought together? They decided to unify all of biology.

Carroll visited Wilson’s office at Harvard University for a free-ranging, hours-long chat. It covered concerns for the future and reminiscing about the past – and morphed into an idea for a global campaign to unite biologists behind the common cause of saving the natural world, a prerequisite for understanding it.

What Happens to Astronaut’s Brain on Way to Mars

According to new research from the University of California, Irvine, and the University of Nevada, exposure to galactic cosmic rays may have long-term adverse consequences to cognition throughout life; and performance decrements, memory deficits, and loss of awareness and focus during spaceflight may affect mission-critical activities. As NASA prepares for the first manned spaceflight to [...] —> Read More
