A Framing Dilema: Disease versus Discovery

[Authors Note: this post starts out as a relatively reasonable consideration of a question, but later morphs into a personal flight of fancy. Feel free to contemplate either the reality or the fantasy or both, as I will be doing.] What is the best way to prompt financial donations to research?

As a graduate student this isn't a question I have had much cause to consider. But yesterday, while meeting with a certain professor in whose lab I have been rotating, the subject was mentioned. Before returning to more pressing topics (aka the current status of my experiments), we talked about the need to develop for neuroscience a fundraising infrastructure similar to that possessed by cancer research. Cancer research, in addition to receiving federal funding from institutions such as the NIH is also fed money by fundraising organizations that appeal for research money directly to public citizens. Setting up a similar situation for neuroscience would not only serve to secure greater funding for research, but would also increase public perception of neuroscience research. Altogether, a win-win situation for neuroscience researchers.

However, my first reaction to the idea was one of skepticism. In my mind, cancer research holds an advantage in the fundraising area in that it seeks to actively cure a disease that the general public can intimately relate to. Most of the potential donators will have either experienced cancer first-hand, or will be only several degrees of separation away from someone who has. Diseases of the brain and potentially much more rare, or at least are more varied, less easily gathered under a single disease name. Cancers of every cell in the body, those possessing individual names, are still ultimately called cancer; the same is not true for diseases of the brain. Surely, I said to the professor, a successful fundraising campaign would require an overarching theme with which an individual citizen could intimately connect; not being the study of a umbrella disease like cancer, would neuroscience be able to generate a unifying principle that could engage the public, convincing them of the desperate need for their donations?

The professor responded that neuroscience didn't need to be about a disease, that the potential for making fundamental discoveries about how the human mind functions is more than enough to engage the public and drive a fundraising campaign. He pointed out that at its heart, cancer research is research about cell division, and that framed as such, neuroscience research has the potential to sound way more sexy, given a carefully considered series of catch-phrases. I freely admit that I never considered cancer research as the study of cell division. As someone intimately connected to the disease (and therefore exposed since an early age to cancer research fundraising campaigns), I have always contemplated the cancer research fundraising as a way to fund breaking research into therapies. But as a research scientist, I know full well that some of the money raised will go to answering basic science questions (such as those of cell division). The success of the cancer research fundraising campaigns is perhaps due to their ability to frame a wide field of research as aspects of an identifiable "enemy". A winning strategy to be sure - but must neuroscience do the same?

Over the past day I've been considering how else to push the need to fund neuroscience research without wielding the shadow of a disease. During the conversation that kicked off this introspective, I was reminded that neuroscience research is seeking to answer fundamental questions about how the brain works. Encapsulated within neuroscience research are questions about how humans sense our world, how we interact with our physical surroundings, and how the neurons (and glia) that compose are brain are capable of generating the realm of human consciousness and experience. Fundamental questions indeed. And in contemplating the enormity of the questions still unanswered in neuroscience I begin to wonder whether the enormity of our ignorance is enough to captivate the public (and, of course, to convince them to support the search for knowledge). Many fundraising slogans these days are derivatives of the theme of fighting a problem, helping people; these are powerful themes to motivate charity. But couldn't themes of discovery, finding the fundamental "how's" that define our individuality, be just as powerful motivators? Is neuroscience due for a introduction (reintroduction?) into public perception similar to that experienced by NASA during the height of the space race? Would attempting to convince more people that neuroscience research is an epic endeavor desirable for scientists? Could elevating the status of research encourage both increases in funding and draw more people to careers in science? I certainly don't know if such a reframing of neuroscience would be possible or successful, either monetarily or holistically. But with a firm personal belief that being as astronaut is just about the most awesome thing ever (a perception aided both by a youthful interest in the space race and a thorough exposure to the classic imagining of the future of astronomical discovery, aka Star Trek), I would love to see a future where a heightened public perception, and appreciation, of neuroscience research yielded both new knowledge and children who grew up dreaming not only of starships, but also of laboratories.

But returning to the original discussion, I'm left wondering which overarching themes in neuroscience research could be catch-phrased into the sorts of slogans appropriate for a P.R./fundraising campaign. Any thoughts?

This week in Science: Octopi and Flies and Polar Bears, oh my!

A quick perusal of the ScienceNOW new released from Science yields a couple of interesting stories fun enough to be shared, but short enough not to warrant full fledged posts. Therefore, here they are, collected in one glorious package. Octopus mimics Flounder, confuses predators and biologists. Mentioned by the Lab Spaces blog (and tweeted and re-tweeted on Twitter last week) is a description of a particular species of octopus that has developed a unique camouflage. The Caribbean octopus mimics the peacock flounder while it swims, presumably to discourage octopus-loving predators with the appearance of an unappetizing flatfish. ScienceNOW provides video of said octopus, doing its best flounder impression.

Early polar bear discovered in Arctic tundra. The fossilized (and presumably frozen) remains of an ancient polar bear has been discovered by scientists in Norway's Svalbard archipelago. The male polar bear lived approximately 120,000 years ago, which for those of you who are counting, was at a time when wooly mammoths were still around. For more on why this discovery is so awesome, see the linked article. Perhaps with this discovery, scientists can finally begin contemplating a most important topic: who would win, polar bear or wooly mammoth? (In the swimming portion of the competition, my money's on the bear.)

Fruit flies contain intrinsic autopilot. Scientists have shown that fruit flies are able to adjust to changing wind currents and flight conditions on a time scale quicker than would be possible if the adjustment was a conscious effort: video at link. This research potentially explains the difficulty of fly swatting.

The award for most cheeky article name goes to: "Why are Dung Beetles so Horny", which is in fact about the unusually large horns of female dung beetles. Originally thought to be used exclusively during fights between males, researchers have identified a role for the horns sported by females, which are sizably larger than those seen on males. In short, it seems that females use their horns to conduct sumo-like wrestling matches. The winner gets the larger ball of dung, and is therefore able to produce more offspring.

The "Best" of Pubmed, Part 1

PubMed: the U.S. National Library of Medicine's great catalogue of biomedical journals. PubMed is the portal to published scientific research, listing over 19 million citations, the good and the bad of what biomedical journals deign to publish. And also the ugly.

Given how much time scientists (especially young scientists) spend worrying about publishing, it is sometimes cathartic to delve into the seedy underbelly of PubMed - to glance through those members of the 19 million citations whose subjects are humorous, awkward, or just plain weird.

Over the past couple of months, I have come across quite a few PubMed jewels: here are some of my favorites. Some of these I found, some were found by other members of the first-year Stanford Neuroscience Program. Some are not suitable for work, children, or those with weak stomachs and vivid imaginations - these I have marked: consider yourself warned.

In the category of Social Interactions:

Dogs catch human yawns. Joly-Mascheroni RM, Senju A, Shepherd AJ. Biol Lett. 2008 Oct 23: 4(5); 446-8.

Instrumental measurement of beer taste attributes using an electronic tongue. Rudnitskaya A et al. Anal Chim Acta. 2009 Jul 30; 646(1-2):111-8.

The inhibitory effects on adult male reproductive functions of crude garlic (Allium sativum) feeding. Hammami I et al. Asian J Androl. 2008 Jul; 10(4):593-601.

In the category of Oh, Ewww.

Nasal leech infestation: report of seven leeches and literature review. Chen WC, Chien CY, Yang CH, Li JH, Hwang CF. Eur Arch Otorhinolayngol. 2009 Dec 27.

In the category of Really BMJ? Really?

A precious case from Middle Earth. Bashir N et al. BMJ. 2004 Dec 18; 329(7480): 1435-6.

Effect of ale, garlic, and soured cream on the appetite of leeches. Baerheim A, Sandvik H. BMJ. 1994 Dec 24-31: 309(6970):1689.

Inexplicably, searching PubMed for the keyword "bouncing" yields this paper:

Qualities of the Ideal Protege. Melanson MA. US Army Med Dep J. 2009 Oct-Dec: 44-6

In the category of Not Suitable for Work/Children/Faint of Heart. (I'm going to leave the titles out in favor of non-rated R descriptions.)

Urologic problems caused by a household appliance during an activity that your mother told you would cause blindness.

Bats engaging in some non-vanilla bedroom practices (with video in the supplementary figures).

This list is far from complete: I expect to be posting more fantastical PubMed citations in the future. Until then, enjoy these, and remember: theres a journal for every kind of study out there.

Panda Genome Sequenced!

Last week in Nature, a large group of scientists announced that they had, for the first time, successfully sequenced the entire genome of the Giant Panda. Their paper describes the extraordinary amount of work required to sequence an entire genome. The researchers extracted the DNA of a 3 year old female living in the Chengdu breeding center. The task: to sequence all of the panda's 20 pairs of autosomes and 1 pair of sex chromosomes. And to do so without breaking the researchers collective banks. The method: create many, many short read sequences of DNA using parallel sequencing technology and piece them together to construct the full sequence. Using parallel sequencing (in particular the llumina Genome Analyser sequencing technology) allowed the researchers to avoid the "prohibitive costs associated with sequencing and assembling large eukaryotic genomes". To that end, the researchers constructed 37 paired-end sequencing libraries, containing a total of 176 gigabases of usable sequence, made up of sequences with an average read length of 52 base pairs. They fed this mass amount of data into a 32 core, 512 GB RAM supercomputer, piecing together a total genome 2.40 gigabases long.

Following the construction of their genome sequence, the researchers went on a meta-analysis spree, comparing the panda genome to both dogs and humans. The group reports that humans, dogs, and pandas all possess approximately 1.4 gigabases of non-repetitive sequence within their genome. Of that 1.4 gigabases, all three species have 846 megabases (~60.4%) in common. Dogs and pandas share ~83% of their non-repetitive sequence, with pandas and humans sharing ~72% and dogs and humans sharing ~64.5%.

The researchersand also searching for several genes of interest to panda aficionados, including the genes encoding for taste receptors. Interestingly, an analysis of the sequence for the T1R1 gene, which encodes the taste receptor for umami, shows a loss-of-function mutation. The authors speculate that this mutation may explain pandas' exclusively herbivorous diet, despite their taxonomic classification of carnivores.

Pandas from the Wolong Natural Nature Reserve

For a gloriously detailed description of the sequencing process, and for more hints at the wonders waiting to be uncovered withinin the panda genome, the original article should be viewed in all its splendor. The Sequence and De Novo Assembly of the Giant Panda Genome. Li R, et al. Nature 463: 311-317 (2010).

A side note: the home of the 3 year old female Panda, the Chengdu breeding center, is a facility working alongside the Wolong Panda Breeding Center to conserve the Giant Panda through extensive breeding programs. The Chengdu center boasts a population of 83 pandas that have been bred from an original population of 6 wild pandas. Pictures of the Chendgu pandas, as well as video of the most recent group born at the Wolong Center are guaranteed to lighten any day with a hearty does of adorable.

Using Oxytocin to Treat Autism

From guest blogger Kelly Zalocusky: Oxytocin is a member of a neuropeptide family, the nonapeptides, that is conserved across vertebrates. Its close cousins include isotocin, particular to fish, and mesotocin, found in amphibians, reptiles, and birds. Members of this family are known for their role in prosocial behavior, particularly maternal and sexual behaviors. In humans, oxytocin has also been associated with trust and with the ability to process facial expressions.

Interestingly, children with autism are frequently found to have low circulating oxytocin and an abundance of oxytocin precursors in the blood, indicating a deficit in the synthesis of this important neuropeptide.

In this week's online early-release of the Proceedings of the National Academy of Sciences, Elissar Andari and colleagues explored the possibility of treating the social symptoms of high-functioning autism spectrum disorder patients with an oxytocin nasal spray. In a computer-simulated ball-tossing game, autism spectrum disorder patients showed no preference among "players" who reciprocated by regularly returning the ball, and those who never returned the ball. In those patients that received the nasal spray, however, trust and preference for the good/friendly player increased relative to the bad/unfriendly player, such that the autistic persons' reponses no longer differed significantly from those of healthy controls. Treated individuals also performed better in a face-scanning task, spending more time focused on socially-relevant face regions, such as the eyes.

Retractions: Failure of Facilitated Communication

Last December, doctors at Liege University hospital declared that a patient thought to be brain dead for 23 years following a car crash victim was actually conscious, and able to communicate. It turns out that apparent communication (enacted using a technique known as "facilitated communication") was merely artifact, and that the patient is, unfortunately, as comatose as was first believed.

Hopefully this public error should stand beside other extraordinary discoveries of higher activity in supposedly comatose patients.  As more techniques are used to examine putatively comatose patients, both scientists and the general public entertain extreme caution during the diagnosis and treatment of severe brain trauma, tempering an enthusiasm for newer, flashier techniques with the use of more classic diagnostic tools.

Note: This is not to say that comatose patients are ever misdiagnosed as being in a permanent vegetative state; there are, unfortunately, too many individual accounts of such an event, and happily, a rising number of patients whose consciousness has been discovered due to advances in modern medicine (see an earlier post from this blog regarding the use of MRI to diagnose brain states). Indeed, given the complexity of the human brain and our uncertain knowledge of how consciousness is generated, it behoves us (doctors, scientists, humans) to be cautious when it comes to the effects of traumatic brain injury, not allowing diagnostic decisions to be swayed by the popularity of any one test, no matter what findings (miraculous or not) it may propose.
