(Â鶹ÒùÔº) —It was an interesting week for physics research, as a team at MIT began taking a second look at pilot-wave theory—they're wondering if, when looked at a certain way —they're taking a new approach to define whether some types of matter are particles, or waves, or whether it's about particles being carried along by waves.

Meanwhile, another team at Chalmers University of Technology announced that . By using sound to communicate with an artificial atom, they are looking to find ways to allow sound to take on the role of light in certain quantum physics situations to demonstrate certain phenomena. And at Princeton University, researchers have begun crystallizing light to create —locking photons together, they suggest, might also help answer some of the fundamental questions physicists still have regarding matter.

Space scientists have been busy as well. One team built —are the planets that exist now part of a normal natural process or was there one or more rare events that led to their formation? More research will have to be done to find better evidence. Also, researchers working with .

In more practical news, researchers at the University of Glasgow reported that they had found —they claim their process is 30 times faster than conventional techniques. Another team at UW-Madison claimed to have developed based on an electric, rather than magnetic, field.

There were also some surprises last week as well: Researchers at Cummings School of Veterinary Medicine announced a potential —they found that a hormone that is involved in mammalian milk production might also help prevent liver cancer. And another team in England has created a . It's actually kind of eerie looking at it.

And finally, if you've been wondering if you, or perhaps some of those around you, are inherently evil, a . They're looking into what is known as the "banality of evil," where ordinary people go along with atrocities, such as the holocaust, as mindless puppets. They think such instances are not banal at all and instead occur because those that go along when ordered to do so, do it out of a feeling of identification—this would mean that people committing such acts have far more choice in the matter than most of us would like to believe.
