Not convinced. It might be, but there is also something to be considered called publication bias. What if they would have discovered that there is no additional fancy function? No big news, maybe questions why the hell spending time on a tissue which is known since ages, even future funding would be at stake. But now they can make a huge fuzz about it. So there is a strong incentive for exxagerating simple facts and even twist and tweak findings to support a compelling message. This looks like a good example for this effect.
