Michael Vassar’s Google TechTalk

Over at Singularity Hub, Aaron Saenz is gushing over Michael Vassar's Google TechTalk.

Aaron said:

Vassar is the president of the Singularity Institute and a prominent advocate for the belief that technologies may develop exponentially in the future.

Not really... my understanding is that the reason that Michael V. talks about the Enlightenment a lot is that he thinks that was the last major boost in human understanding and reason. He tends to focus more on human thinking than on our technologies, and sees the latter as an outgrowth of the former. That's the primary idea behind the Vingean Singularity as well. (Remember that one?)

One of the apparent purposes of Less Wrong is to start a new Enlightenment. The jury's still out on that one, but it doesn't hurt to try.

Repairing the Heart

From Eurekalert:

Gladstone scientists discover new method for regenerating heart muscle by direct reprogramming

Next-generation reprogramming of native cells offers therapeutic advantages

Scientists at the Gladstone Institute of Cardiovascular Disease (GICD) have found a new way to make beating heart cells from the body's own cells that could help regenerate damaged hearts. Over 5 million Americans suffer from heart failure because the heart has virtually no ability to repair itself after a heart attack. Only 2,000 hearts become available for heart transplant annually in the United States, leaving limited therapeutic options for the remaining millions. In research published in the current issue of Cell, scientists in the laboratory of GICD director Deepak Srivastava, MD, directly reprogrammed structural cells called fibroblasts in the heart to become beating heart cells called cardiomyocytes. In doing so, they also found the first evidence that unrelated adult cells can be reprogrammed from one cell type to another without having to go all the way back to a stem cell state.

The researchers, led by Masaki Ieda, MD, PhD, started off with 14 genetic factors important for formation of the heart and found that together they could reprogram fibroblasts into cardiomyocyte-like cells. Remarkably, a combination of just three of the factors (Gata4, Mef2c, and Tbx5) was enough to efficiently convert fibroblasts into cells that could beat like cardiomyocytes and turned on most of the same genes expressed in cardiomyocytes. When transplanted into mouse hearts 1 day after the three factors were introduced, fibroblasts turned into cardiomyocyte-like cells within the beating heart.

"Scientists have tried for 20 years to convert nonmuscle cells into heart muscle, but it turns out we just needed the right combination of genes at the right dose," said Dr. Ieda.

TEDxBerkeley – Bradley Voytek – 04/03/10

Bradley Voytek is completing his Ph.D. in Neuroscience at the University of California, Berkeley. He studies the role of brain rhythms and electrophysiology in attention and memory by working with patients with electrodes implanted in their brains, patients who have had portions of their skull surgically removed, and patients with brain lesions. By working with these rare groups of people and using sophisticated analysis methods he aims to learn how the brain communicates to improve patient outcomes.

EvPsych/CogSci/Neuroscience Meets English Literature

I can appreciate this new trend because it mirrors part of the intellectual dynamic between me and my girlfriend, who is an English/Theatre major. From The New York Times:

Jonathan Gottschall, who has written extensively about using evolutionary theory to explain fiction, said “it’s a new moment of hope” in an era when everyone is talking about “the death of the humanities.” To Mr. Gottschall a scientific approach can rescue literature departments from the malaise that has embraced them over the last decade and a half. Zealous enthusiasm for the politically charged and frequently arcane theories that energized departments in the 1970s, ’80s and early ’90s — Marxism, structuralism, psychoanalysis — has faded. Since then a new generation of scholars have been casting about for The Next Big Thing.

Word! The ground here is fertile. The politically charged and arcane theories that energized departments in the 1970s - early 90s are mostly scientifically false. Discussions of them are quaint, like alchemy. By embracing neuroscience and evolutionary psychology, analysis of literature can reach a new level of intellecual rigor. This is similar to what philosophy has done -- many philosophers study neuroscience and cognitive science with great interest.

Here's another quote from the article:

Interest has bloomed during the last decade. Elaine Scarry, a professor of English at Harvard, has since 2000 hosted a seminar on cognitive theory and the arts. Over the years participants have explored, for example, how the visual cortex works in order to explain why Impressionist paintings give the appearance of shimmering. In a few weeks Stephen Kosslyn, a psychologist at Harvard, will give a talk about mental imagery and memory, both of which are invoked while reading.

You'd think this would be an obvious thing to look into, so it's great that people are looking into it! Neurosicence and other brances of cognitive science are one of the best ways that we humans can come to better understand ourselves. Cognitive science and evolutionary psychology have given our species more concrete self-understanding than thousands of years of meditation, self-reflection, mythological theories, and navel-gazing.

Some people are uncomfortable with evolutionary psychology because it maintains that human beings are "just" animals that evolved features to deal with complex adaptive challenges, but many have realized this was true essentially since Darwin. Even though this can make evpsych unappealing, its explanatory power is so extensive that it will keep creeping into the humanities whether established professors like it or not. Confusing and complex topics demand explanatory theories.

H/t to Futurisms for the link, where Ari Schulman complains:

The crisis of the humanities implicit in the title of the Times piece arises from a sort of malaise of academic purposelessness, which is in turn related to a larger societal phenomenon wherein we increasingly believe that science is the only solid rock we have to stand on for understanding the world and how we should function in it.

Yes. "Science" is nothing more than "understanding the world". "How we should function in it" is considerably more subjective and outside of science, however. It's 2010, and people are still objecting to science as a means of understanding the world and ourselves? Very quaint.

The Futurisms folks should understand that we can embrace science for its explanatory power, but that doesn't mean that we should use science to upgrade our bodies willy-nilly. The two concepts are not and shouldn't be connected. We should be very careful about how we approach human enhancement, and not embrace it all uncritically just because it has to do with "science".

New Book Examines the Flawed Human Body

From the Genetic Archaeology blog:

Humanity's physical design flaws have long been apparent - we have a blind spot in our vision, for instance, and insufficient room for wisdom teeth - but do the imperfections extend to the genetic level?

In his new book, Inside the Human Genome, John Avise examines why - from the perspectives of biochemistry and molecular genetics - flaws exist in the biological world. He explores the many deficiencies of human DNA while recapping recent findings about the human genome.

Distinguished Professor of ecology & evolutionary biology at UC Irvine, Avise also makes the case that overwhelming scientific evidence of genomic defects provides a compelling counterargument to intelligent design.

Here, Avise discusses human imperfection, the importance of understanding our flaws, and why he believes theologians should embrace evolutionary science.

Our brains and bodies are both full of flaws. According to the pre-transhumanist worldview, the plan is just to sit around for the rest of eternity with these flaws, even as we colonize the Galaxy. According to the transhumanist worldview, the plan is to analyze these flaws, debate whether they are flaws or not, and consider fixing them if it seems practical and desirable. The latter makes sense, the former doesn't.

The New Scientist CultureLab blog has more info on the book.

Naked Mole Rats Return

Naked mole rats -- is there anything they can't do? A University of Illinois at Chicago press release reminds us that mole rats can withstand oxygen deprivation for up to 30 minutes, which may give us clues for protecting the brain from stroke.

Another recent brain-related news item concerned therapeutic hypothermia to minimize trauma to injured brain issue. It seems as if there is a wave of research in this direction.

Praise Luna — “Significant” Water Found on Moon

Holy crap, the Moon has a ton of water. 25 gallons were kicked up by the probe that impacted it a month ago. This is huge, huge news, because everyone thought that the Moon was as dry as a bone. I see that various studies predicted this recently. A pessimistic article from Space.com from a month ago said "one ton of the top layer of the lunar surface would hold about 32 ounces of water", but now it's looking like a lot more.

Now all we need to do is ship nitrogen and other essential nutrients there in huge amounts using mass drivers, a nuclear cannon, or space elevator, put up a few aerogel-insulated domes, and start partyin'! (Well, maybe not exactly, but water does give us huge amounts of oxygen, which we need to breathe, and hydrogen, which can be used as fuel.) This article from LiveScience has more details.
