Scientists are using computer models to answer what many believe is one of science's most puzzling questions: How did heavy metals like gold get to Earth?
There are two candidates, neither of which are located on Earth—a supernova, a massive star that, in its old age, collapsed and then catastrophically exploded under its own weight—or a neutron-star merger, in which two of these small yet incredibly massive stars come together and spew out huge amounts of stellar debris.
In a recently published paper in the journal Physical Review Letters , researchers detail how they are getting close to an answer.
"At this time, no one knows the answer," says Witold Nazarewicz, professor of physics at the Facility for Rare Isotope Beams at Michigan State University. "But this work will help guide future experiments and theoretical developments."
From the paper, "Impact of Nuclear Mass Uncertainties on the r Process."

Throw in a <blink> tag and you'd have my Geocities page from back in the day.

Earth's gold was in our nostalgia all along.

Someone said that SoylentNews has been redesigned. In my browser it looks the same except that the link from the upper left corner to the main page, has disappeared. Is there any chance that it can be re-added? I found it more convenient than the link in the middle left under "Sections" and more convenient than editing the URL in the address bar.

I don't know if this helps your search for the missing link, or not:
In my browser, the link in question is now animated- zooming across the top of the page from right to left.

I tried viewing the site in a different browser and it works just as you describe. So that's all right then.

I love it. Can we keep this design forever?

I'm going to get eye-cancer from all this blinking and shit. This is anything should show that nostalgia for ye' olden days is just bullshit. What a long way design wise we have come in a couple of decades.

Did you check the source (or viewed the site with an old browser) that there's really no blink tag? Because modern browsers don't honour it.
