Higher levels of a protein called S-100 in melanoma patients may correlate with a higher risk of the disease returning, say researchers. The study tested serum samples from 103 patients treated with high-dose interferon an average of eight years prior. When the researchers examined levels of S-100 in the samples, they found that the higher the level of the protein, the greater likelihood the disease had returned.

Two geologists from the Geological Survey of Norway will drill into 2.5 to 2 billion year-old rocks in Russia to seek to understand the interaction between geological processes that created the "modern Earth." The increase of oxygen in the atmosphere marked the very beginning of the "modern Earth" as it functions today. The rocks from the birth of the "modern Earth" have isotopic and chemical signatures that contain proof of dramatic events like the break-up of continents, volcanism and repeated global ice ages or the "Snowball Earth."

What do you when you've got millions of dollars, no steady day job, and plenty of vocal critics that do their best to berate you knowing full well that they could never do your job if given the chance? We might just ask Bruce Willis that very question, but thankfully for all us, he's already responded. Apparently, Mr. Willis not only finds his way around internet message boards that focus on his films, but he doesn't hesitate to join in on the oftentimes testy conversations and give users his platinum-laced two cents. In a recent go 'round in regard to Die Hard 4, Bruce was caught mouthing off to disbelievers and carpers alike, and while a select few were adamant that this so-called Walter B. was little more than an overzealous fanboy, Bruce did the honorary thing and offered to prove it. The actor actually requested that a fellow iChat / Mac user hit him up for a momentary video chat in order to show his face, and sure enough, the most vocal doubter was indeed put in place rather quickly. Big fan of the ego, Bruce.
