Here's a paper that combined a 30 year study on intake with MRI data and came to similar conclusions (no safe level of consumption and no observed benefit from low-dosage consumption).

One thing to keep in mind when reading these papers is that a "unit" of alcohol in these studies is often equivalent to about half a standard drink in the US. So when they talk about 7 units a week, it's not 7 drinks, it's usually 3.5 drinks.
