I dont have time to watch the video right now, but I saw his photo and said to myself, I've met that guy. I dont what he was talking about in this video but i bet it is "enlightening"....
It looks like a giant potato in space.
And yet, the information in this model is the sharpest view we have of how gravity varies across the Earth.
The globe has been released by the team working on Europe's Goce satellite.
It is a highly exaggerated rendering, but it neatly illustrates how the tug we feel from the mass of rock under our feet is not the same in every location.

WASHINGTON -- NASA's Swift, Hubble Space Telescope and Chandra X-ray Observatory have teamed up to study one of the most puzzling cosmic blasts yet observed. More than a week later, high-energy radiation continues to brighten and fade from its location.
Astronomers say they have never seen anything this bright, long-lasting and variable before. Usually, gamma-ray bursts mark the destruction of a massive star, but flaring emission from these events never lasts more than a few hours.
Although research is ongoing, astronomers say that the unusual blast likely arose when a star wandered too close to its galaxy's central black hole. Intense tidal forces tore the star apart, and the infalling gas continues to stream toward the hole. According to this model, the spinning black hole formed an outflowing jet along its rotational axis. A powerful blast of X- and gamma rays is seen if this jet is pointed in our direction.
On March 28, Swift's Burst Alert Telescope discovered the source in the constellation Draco when it erupted with the first in a series of powerful X-ray blasts. The satellite determined a position for the explosion, now cataloged as gamma-ray burst (GRB) 110328A, and informed astronomers worldwide.
As dozens of telescopes turned to study the spot, astronomers quickly noticed that a small, distant galaxy appeared very near the Swift position. A deep image taken by Hubble on April 4 pinpoints the source of the explosion at the center of this galaxy, which lies 3.8 billion light-years away.

In technology that is lifted straight from Robocop, Brazilian cops will be outfitted with glasses that can scan faces in a crowd and automatically pick out criminals. The glasses use advanced facial recognition technology that can scan 400 faces a second at 50 yards away.
Bionerd is one of my favorite science posters on Youtube.
Here are some theories from her about Fukushima Daiichi. The 2nd half is slightly more interesting. All the water they are dumping on the reactor may not be cooling it down, but actually creating more fissionable material.

Having just attended a conference on High Level Radioactive Waste Management and listening to panels of speakers of people who are plugged into the situation as much as any "outsider" can be plugged in (Japanese culture is very private and that extends to situations like this), I can say with quite a bit of certainty that more fissionable material is not being created.

I'm not a physics major, so while I know the higgs boson is important to science; why is it important, and what would the future of life/technology be if it's proven?
Actually finding it would kind of be a letdown, since it's what's predicted by the current models, and finding it wouldn't give us any new information.
A really interesting result would have been to not find it, or find something different, that would have pointed a way to new theories.

So assuming the report is true, it said the higgs boson decayed into photons. I thought the higgs boson had mass where as photons didn't, and so if that's true...where would the mass have gone?

From what I remember in university, it is bascially a missing puzzle piece for many models in physics. If it can be proven to exist, then it will make developing future models a lot easier. It will also allow physicists to ignore the Higg-less models and concentrate on ones that assume there is a Higgs boson.
Personally, I always thought the presence of a Higgs boson would be too convenient. It seemed too cookie cutter perfect.

Really short simplified answer....
