Communion Of Dreams


Sure beats graverobbing.

Via BoingBoing, this fascinating application of scanning and augmented reality technology:

Access to good dissection models is always problematic, but is absolutely crucial for medical education.  Donor cadavers are often in short supply, and they have the problem that they’re, well, dead. Meaning that they died from something. And under even the best of circumstances, that will have an impact on the suitability for the student’s experience in studying a healthy body.

But with this kind of technology, a student can encounter a wide variety of body types: young, in the ‘prime of life’, aged, with any number of different medical issues (or none at all). Male. Female. Pregnant. Potentially, even as the body is “living”.

Amazing.

Fading.

As we were on our morning walk, I rolled my right hand over a bit and looked at the blade of it. My wife looked down at it as well.

“How is it doing?”

I flexed the hand back and forth a bit. The pale yellow-green of a late-stage bruise was still very evident.

U.S. Warns Syria on Chemical Weapons

WASHINGTON — President Obama warned Syria on Monday not to use chemical weapons against its own people, vowing to hold accountable anyone who did, even as American intelligence officials picked up signs that such arms might be deployed in the fighting there.

The White House said it had an “increased concern” that the government of President Bashar al-Assad was preparing to use such weapons, effectively confirming earlier reports of activity at chemical weapons sites. The administration said it would take action if they were used, suggesting even the possibility of military force.

“Today I want to make it absolutely clear to Assad and those under his command: The world is watching,” Mr. Obama said in a speech at the National Defense University in Washington. “The use of chemical weapons is and would be totally unacceptable. If you make the tragic mistake of using these weapons, there will be consequences and you will be held accountable.”

From The Long, Twilight Struggle:

Londo Mollari: Refa, any force attempting to invade Narn would be up to its neck in blood–its own!

Lord Refa: We have no intention of invading Narn. Flattening it, yes–but invading it? We will be using mass drivers. By the time we are done their cities will be in ruins, we can move in at our leisure!

Londo Mollari: Mass drivers? They have been outlawed by every civilized planet!

Lord Refa: These are uncivilized times.

Londo Mollari: We have treaties!

Lord Refa: Ink on a page!

Chemical Weapons Convention

The Chemical Weapons Convention (CWC) is an arms control agreement which outlaws the production, stockpiling, and use of chemical weapons. Its full name is the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction. The agreement is administered by the Organisation for the Prohibition of Chemical Weapons (OPCW), which is an independent organization based in The Hague, Netherlands.

The main obligation under the convention is the prohibition of use and production of chemical weapons, as well as the destruction of all chemical weapons. The destruction activities are verified by the OPCW. As of January 2013, around 78% of the (declared) stockpile of chemical weapons has thus been destroyed.[5][6] The convention also has provisions for systematic evaluation of chemical and military plants, as well as for investigations of allegations of use and production of chemical weapons based on intelligence of other state parties.

Currently 188 states are party to the CWC, and another two countries (Israel and Myanmar) have signed but not yet ratified the convention.[1]

Syria is one of six UN member states who are not signatories to the Convention.

Syria crisis: ‘Strong evidence’ of chemical attacks, in Saraqeb

The BBC has been shown evidence which appears to corroborate reports of a chemical attack in the northern Syrian town of Saraqeb last month. Eyewitnesses and victims say that government helicopters dropped at least two devices containing poisonous gas on the town.

The Syrian government says it did not and will not use chemical weapons.

Shortly after midday on 29 April, the town of Saraqeb came under attack from government military positions about five miles (8km) away. A local activist we met filmed as the shells landed.

As we were on our morning walk, I rolled my right hand over a bit and looked at the blade of it. My wife looked down at it as well.

“How is it doing?”

I flexed the hand back and forth a bit. The pale yellow-green of a late-stage bruise was still very evident.

“It’s healing. The pain has gone from being that bright, intense flash you get from a broken bone to a dull but substantial ache. That tells me that it’s knitting back together properly. A few more days of not stressing the hand, and it’ll be OK.”

We paused, watched the dog take care of his business. As I reached down with a plastic bag to remove the results from the neighbor’s lawn, I thought about how lucky I was.

Yes, this *is* the future.

How cool is this?

Gorgeous:

The Rose

The spinning vortex of Saturn’s north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image from NASA’s Cassini spacecraft. Measurements have sized the eye at a staggering 1,250 miles (2,000 kilometers) across with cloud speeds as fast as 330 miles per hour (150 meters per second).

A fascinating short video and full explanation can be found on NASA’s site:

PASADENA, Calif. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.

In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

Very cool. If I ever have reason to revise Communion of Dreams, I would certainly include reference to The Rose since most everything happens on and around Titan.

Whoa.

No, really … whoa.

Is there anybody out there?*

From the opening pages of Communion of Dreams:

Jon sat there for a moment, trying to digest what Seth said. According to what pretty much everyone thought, it wasn’t possible. SETI, OSETI, META and BETA had pretty much settled that question for most scientists decades ago, and twenty years of settlement efforts throughout the solar system hadn’t changed anyone’s mind. Even with the Advanced Survey Array out at Titan Prime searching nearby systems for good settlement prospects, there had never been an indication that there was an intelligent, technologically advanced race anywhere within earshot.

It’s one of the very basic questions of space science: are we (sentient beings) unique? Rare? Common? There are a lot of ways to think about it, and here’s a nice piece on NPR discussing some of the relevant parts of the question and what we’re doing about it.  An excerpt:

So, to address the first part of the question we must find out how unique the Earth is. We then should figure out how unique life, and humans, are. Fortunately, thanks to NASA’s Kepler mission, we are making huge progress in the first part of the answer. A key finding is that the majority of stars (around 70 percent) have at least one planet orbiting around them. Based on the data so far (2,740 planet candidates and 115 confirmations), Kepler scientists estimate that some 17 percent of these are Earth-size, meaning with similar mass and rocky composition as the Earth, and possibly close enough to their parent star that water, if present, could be in its liquid state.

More good news arrived on this front earlier this month as NASA authorized the construction of Kepler’s successor, TESS (for Transit Exoplanet Survey Satellite). With launch scheduled for 2017, TESS will survey a much wider area of the sky than Kepler, while focusing mostly on stars that are closer. This way, it will use spectroscopy to resolve at least part of the atmospheric composition of the exoplanets. The goal is to find telling signs of life-related compounds such as ozone, water, carbon dioxide and, if we’re really lucky, even chlorophyll. Successful detection would be very exciting, as it’d point to what optimists expect, a few fairly close Earth-like planets with metabolizing beings.

I hope I live long enough that science is able to make a definitive affirmation of life, then intelligent life, outside our own planet.

Until then, well, there’s science fiction.

*Seemed appropriate.



I can see clearly now … *

OK, the neuroscience behind this is beyond me — hell, the actual process of creating these sample is as well — but the effect is pretty clear, and the implications for research are very exciting:

The process can also be used for organs other than the brain. Very cool.

Nicely done.

I’ve seen this movie.

I know how it ends.

Oh, shit.
