Interesting that many of the comments here attempt to label this as false research simply because it's taking one state and changing it to another.

Absent from the conversation seems to be agreement on what exactly "time" is.

Much has been studied and said about time, but if we think of time as being something other than an observable change—or that of a recognizable, unified state to one of chaos, aka entropy—what is it?

I'd add here that the observations of this research aren't that striking. We've known for some time that time may not be a single direction arrow but rather one pointing both ways, dependent on what we're observing and our classification of what's possible.

In his book Your Brain is a Time Machine, Dean Buonomano gives an excellent and well-written example of how studies like the one reported here actually work. A favorite quote of mine from that section sums the point as so:

"Decreases in entropy are improbable, not impossible, and given enough time the improbable becomes probable."

These were dumb comments for me to make, I wish HN supported deletion at times like these. Oh well.
