Is gravity not actually a force? Forcing theory to meet experiments

From ArsTechnica:

With the advent of quantum theory over the past 100 years, scientists have been able to develop an elegant mathematical framework capable of uniting three of the four fundamental forces that are thought to exist in the universe. The fourth, gravity, still remains the fly in the ointment, and has resisted unification to this point. Early last year, Dutch theoretical physicist Erik Verlinde published a manuscript to the arXiv that purports to explain why science cannot reconcile all four fundamental forces. According to him, it is simple: “gravity doesn’t exist.”

Battery turns entropy into electricity

From Chemistry World:

When fresh water rivers flow into the sea the concentration difference leads to a change in entropy. US researchers have developed a battery that generates power from that entropy difference.
