Discovered: It's not quite an invisibility cloak, but it's a start; men are more likely to commit research fraud; multitasking causes more mistakes; the risks scientists are considering in Davos.
Ghost cloaks can make objects spectral. The new invention from a team of physicists at Southeast University in Nanjing, China won't give you the ability to sneak around entirely unseen, but it's almost as good as an invisibility cloak. Tie Jun Cui and colleagues were able to build a device that scatters light in such a way that objects appear to have ghost doubles on either side of them. Their self-described "ghost cloak" could be useful for "security enhancement," the researchers write. Or just spooking the bejeezus out of trick-or-treating neighborhood children during Halloween.

Men are more likely to cheat at science. A small contingent of scientists aren't rigorously searching for the truth—they're fabricating data and skewing studies to boost their careers. And after studying those who commit scientific fraud, Albert Einstein College of Medicine of Yeshiva University microbiologist Arturo Casadevall noticed that men were proportionally much more likely to put out phony papers than their female colleagues. A review of 228 cases of scientific misconduct found that the gender disparity between fraudulent researchers was greatest amongst college faculty members. Out of 72 cases, only nine deceptive studies were led by female faculty members. "The fact that misconduct occurs across all stages of career development suggests that attention to ethical aspects of scientific conduct should not be limited to those in training, as is the current practice," Casadevall writes.
