Jiang et al. (2015) present eight new transit light curves of WASP-43b, and by combining it with previously obtained data, the team found that the orbit of WASP-43b is likely to be decaying. The variations in the transit timings appear to indicate that the orbital period of WASP-43b is decaying at a rate of roughly 3 seconds per hundred years. At this rate, WASP-43b is expected to be tidally disrupted by its host star in just a few million years.
