Sorry about the mild language. It’s in the original vid.

“If you were to blow up our spheres to the size of the Earth, you would see a small ripple in the smoothness of about 12 to 15 mm, and a variation of only 3 to 5 metres in the roundness,”

Now that’s impressive.

The roundest object in the world.

Scientists at Wake Forest University Baptist Medical Center are about to embark on a human trial to test whether a new cancer treatment will be as effective at eradicating cancer in humans as it has proven to be in mice.

The treatment will involve transfusing specific white blood cells, called granulocytes, from select donors, into patients with advanced forms of cancer. A similar treatment using white blood cells from cancer-resistant mice has previously been highly successful, curing 100 percent of lab mice afflicted with advanced malignancies.

“In mice, we’ve been able to eradicate even highly aggressive forms of malignancy with extremely large tumors,” Cui said. “Hopefully, we will see the same results in humans. Our laboratory studies indicate that this cancer-fighting ability is even stronger in healthy humans.”

Excellent! Full article here.

What’s it like to suddenly be able to see in 3D?

Exciting news. And it was skin cancer, which is particularly important to me and my family.

The 52-year-old, who was suffering from advanced skin cancer, was free from tumours within eight weeks of undergoing the procedure.

After two years he is still free from the disease which had spread to his lymph nodes and one of his lungs.

Bring it on!

Some cool science videos.

Physicist Brian Cox gave a talk at the recent Ted Talks conference on the impending operation of the Large Hadron Collider. It may sound geeky and inaccessible, but Cox is an engaging and genuine presenter. It’s very much an everyman, popular-science type talk, but it touches on a subject that I’m very interested in. Do yourself a favor and take 20 minutes to watch his excellent talk. That way you’ll understand the significance when, a year or so from now, I make an effusive blogpost that they’ve found the Higgs Boson.

On a sidenote, how can you not love Brian Cox? He holds a chair in particle physics at the University of Manchester, but looks more like a member of the Beatles. I hope this guy gets more face-time with the public. Who knows, we may have school girls swooning after a physicist- surely, something that’s never happened in this universe.

From the people-who-don’t-get-it department comes this story about a lawsuit in US court trying to stop the LHC from going online because it might, y’know, destroy the universe. Among other reasons this is a stupid idea is this: the LHC and CERN aren’t even in the US!

Matt has a good summary of the Large Hadron Collider. From his site:

To give some idea of what kind of energy we’re talking about, the everyday energy scales we live at are a few hundred (in energy units of electron volts…don’t worry about that, the relative scale is what matters). The surface of the sun is a few thousand.

LHC is going to get up to about 14,000,000,000,000. That’s impressive, but the highest possible, the Planck scale, is 20,000,000,000,000,000,000,000,000,000 … so we have a ways to go.

But here’s the fun part…like I said, physics changes as energy increases. But, it doesn’t change continuously. Things may look the same for a big range of energy, and as you increase, you don’t see anything new. At other points, however, there may be a HUGE change that happens really suddenly as you increase energy.

And the experimental work we’ve been able to do for a long time now has been in an energy range where theories don’t expect much to change. That is, until now.
The energy range the LHC will get to once they fire it up in a couple of months is just on the other side of where we expect the next big jump to be.

Matt is a good writer and teacher (in addition to being a crack Ratchet and Clank player). Check out his extended explication of the LHC.

In five hundred years I believe the world will look back on early 21st century humanity and will see Dean Kaman much the same way that we now look back on Leonardo da Vinci. Kamen has done a lot of things in his long and eclectic career, but I think he’ll be remember most not for the crazy thing he invented a few years ago, but for something much more mundane and important.

Kamen was on the Colbert Report last night showing off his latest invention. Colbert sticks to his schtick, unfortunately, and tries to milk some comedy out of an invention that I believe is truly revolutionary and important. Check it out.

Kamen is one of those guys that I’d really, really like to meet. He seems to have a knack (Segway jokes aside), for picking one or two really intractable problems and then focusing on them (with his brilliant team) until he gets them licked.

I mean, how cool is it to invent a relatively cheap water purifier that can basically change the lives of 1,200,000,000 people? How’s that for a contribution?

EETimes.com is reporting that a group of Canadian and German researchers have created a room temperature superconductor. This is huge news- really huge. Like, cure-for-cancer big in the energy world. I’m sure there are a myriad of details to work out, and it’ll probably be 10-15 years until we see this stuff commercially available, but if they could replace our entire electrical grid,including all of the wiring in our house (an admittedly non-trivial assumption), our energy usage would plummet significantly.

“If you put hydrogen compounds under enough pressure, you can get superconductivity,” said professor John Tse of the University of Saskatchewan. “These new superconductors can be operated at higher temperatures, perhaps without a refrigerant.”

He performed the theoretical work with doctoral candidate Yansun Yao. The experimental confirmation was performed by researcher Mikhail Eremets at the Max Plank Institute in Germany.

The new family of superconductors are based on a hydrogen compound called “silane,” which is the silicon analog of methane–combining a single silicon atom with four hydrogen atoms to form a molecular hydride. (Methane is a single carbon atom with four hydrogens).

Researchers have speculated for years that hydrogen under enough pressure would superconduct at room temperature, but have been unable to achieve the necessary conditions (hydrogen is the most difficult element to compress). The Canadian and German researchers attributed their success to adding hydrogen to a compound with silicon that reduced the amount of compression needed to achieve superconductivity.

So obviously now we need to deal with high-pressure here, but I’m sure they’re working on that. Room temp superconductors have been something of a holy grail in science for decades. If they really managed this feat then keep your eyes on this technology. Things are about to get really interesting.

I spent some time cleaning out the library this afternoon. Our “library” is really just the pretentiously named fourth bedroom in our house. Instead of an extra bed there are four bookshelves, a computer, and a lot of other stuff that needed to be sorted, tossed, or re-filed into other categories and locations to be tossed later.

I went through some of my books (they multiply, you know) and came to my Science Fiction section. Had a lot of Asimov books, naturally, a few Brin, Card, Sheffield, and a whole bunch of Arthur C. Clarke. 2001, 2010, 2069, 3001, The Rama series, on and on. I decided that his stuff passed the threshold of keepability (meaning: too good to toss. I chucked some old or outdated or duplicate stuff). So I re-shelved them and thought “gee, I’m going to have to read some of those again soon”. Clarke is one of those seminal, always-present writers in the SF world. His books were a big, big part of my life growing up. He was really the very first science fiction author of any standing that I read in my youth and I always appreciated how his style of writing was clear and complex at the same time. He could get across some pretty intricate ideas in a way that was easy to understand, without talking down to a 12 year old. In spite of his annoying tendency to kill his main characters at the end of his books in order to Make A Bigger Point, I’ve always liked his style of writing.

Clarke made his biggest contributions during the 60’s and 70’s and has been floating serenely on his fame ever since while living in, of all places, Sri Lanka.

I was surprised and saddened to see that Arthur C. Clarke died in his home today at the age of 90. An era has ended.

What happens when scientific achievement becomes too fast to keep up with? Can we really then be said to be advancing if we can’t take advantage of the knowledge? Scienceblog looks into it.

Classical Values is linking to a couple of YouTube videos on the ITER fusion reactor prototype. The prototype won’t even be finished until 2020, with no definite plans to be building a real reactor until 2050. Talk about long-term! Still, this sucker is huge.

The History Channel is showing a 2 hour special this Monday on what would happen to the planet’s cities and infrastructure if all the people suddenly disappeared. Looks interesting, and I hope they put it online soon.
