My connectome, myself

The human brain has 100 billion neurons, each of which is connected to many others. Neuroscientists believe these connections hold the key to our memories, personality and even mental disorders such as schizophrenia. By unraveling them, we may be able to learn more about how we become our unique selves, and possibly even how to alter those selves.

Mapping all those connections may sound like a daunting task, but MIT neuroscientist Sebastian Seung believes it can be done — one cubic millimeter of brain tissue at a time.

“When you start to explain how difficult it would be to find the connectome of an entire brain, people ask, ‘What’s the point? That seems too far off.’ But even finding or mapping the connections in a small piece of brain can tell you a lot,” says Seung, a professor of computational neuroscience and physics at MIT.

Even more than our genome, our connectome shapes who we are, says Seung, who outlines his vision for connectome research in a new book, Connectome, published this month by Houghton Mifflin Harcourt. “Clearly genes are very important, but because they don’t change after the moment of conception, they can’t really account for the effects of experience,” he says.

A streambed of consciousness

Seung envisions the brain’s connections as the “streambed” through which our consciousness flows. At a molecular level, that streambed consists of billions of synapses, in which one neuron sends signals to the next via chemical neurotransmitters. While scientists once believed that synapses could not be changed after formation, they now know that synapses are continuously strengthening, weakening, disappearing and reforming, as we learn new things and have new experiences.

While neuroscientists have long hypothesized that the key to our unique selves lies in those connections, this has proven impossible to test because the technology to map the connections did not exist. That is now changing, due to the efforts of Seung and a handful of other neuroscientists around the world.

At the Max Planck Institute for Medical Research in Heidelberg, Germany, neuroscientists in the laboratory of Winfried Denk have taken extremely thin slices of brain tissue and generated electron-microscope images of all the neural connections within each slice. However, the next step — mapping those connections — is extremely time-consuming. Seung estimates that it would take 100,000 years for a lone worker to trace the connections in one cubic millimeter of brain tissue.

To help speed that up, Seung and his colleagues have developed an artificial intelligence (AI) system, which they presented at the International Conference on Computer Vision and the Neural Information Processing Systems Conference in 2009. However, the system still requires human guidance, so the researchers are enlisting the help of the general public through a website called eyewire.org. “The brain is like a vast jungle of neurons,” Seung says. “They’re like trees that are all tangled up together, and people can help us explore that.”

Participants in the Eyewire project will help guide the computer program when it loses track of where a neuronal extension goes amidst the tangle of neurons.

“The person can click the mouse and say color here, and the computer starts coloring again, and keeps going, and then stops again when it’s uncertain. So you’re guiding the computer,” Seung says. Furthermore, the AI system becomes “smarter” as people guide it, so it will need less and less help as it goes on.

Rather than tackling the human brain right away, the researchers are beginning with a 300- by 350- by 80-micron slice of mouse retinal tissue. Images of just this small piece of tissue take up a terabyte of data, or enough to hold 220 million pages of text.

In a review published in New Scientist, Terrence Sejnowski, the Francis Crick Professor of Computational Neurobiology at the Salk Institute, says the book “gives a sense of the excitement on the cutting edge of neuroscience.” Sejnowski points out that connectomics, just like genomics, will be aided by the rapid advance of technology. “Once a certain threshold has been achieved, something that seemed impossible becomes possible, and soon becomes routine,” he writes.

Miswired brains

While everyone’s connectomes are different, extreme differences may account for mental disorders such as autism and schizophrenia. Neuroscientists have long speculated that autism and schizophrenia are caused by problems in brain wiring, but haven’t been able to test that theory. Once a typical human connectome has been mapped, scientists will be able to compare it to the wiring diagrams of small chunks of the brains of mice engineered to express autism or schizophrenia symptoms, in the hopes of figuring out why those disorders arise and, potentially, how to treat them.

“Finding those differences, of course, is not a cure or treatment, it’s just a starting point. But I would argue that being able to see those differences would be a huge step forward,” Seung says. “Imagine studying infectious diseases before there were microscopes. You could see the symptoms, but you couldn’t see the microbes. That’s why, for a long time, people didn’t believe schizophrenia had a biological basis, because they looked at the brain and there was nothing obviously wrong.”

In the last section of Connectome, Seung addresses some futuristic applications of connectomics, drawn directly from science fiction — ideas such as uploading human brains into computers or freezing bodies to preserve them until technology is developed to bring them back to life.

“My goal in those chapters is to point out that we can start to examine those dreams in a critical way,” Seung says. For example, he suggests that cryogenics is only a feasible plan if it can be shown that the connectome survives the freezing and thawing intact. “My point in those chapters is to introduce a dose of science into science fiction.”

Audio: 165-Million-Year-Old Cricket Song Comes Back to Life

A cricket song last heard 165 million years ago has been played again.

To reconstruct the sound, paleontologists compared microscopic wing structures of fossil Archaboilus musicus, a Jurassic ancestor of modern crickets, to contemporary wings. Crickets sing — or, technically, “stridulate” — by rubbing together the ridged edges of their wings.

From noises generated by modern features, the researchers could extrapolate what A. musicus sounded like. (To listen, play the file below.) Theirs was a powerful song, almost certainly used to attract mates.

What does the song tell us? To the researchers, it suggests that cricket songs are ancient, rather than a recent evolutionary innovation, and hints at the sonic richness of the Jurassic world.

The cricket’s song is not, however, the oldest noise in the world. That honor goes to the sound of our universe’s birth.

How NASA Makes Those Incredible High-Res Images of Earth

In recent weeks, a pair of high-resolution images of the Earth has captivated the public. Taken by the Suomi NPP satellite, these pictures portray our planet’s incredible beauty with 8,000- by 8,000-pixel and 11,500- by 11,500-pixel detail.

How were these highly detailed images created? The satellite flies 512 miles above the Earth, but the images appear as if they were taken from a much higher perspective: an altitude of 1,242 for the first image and 7,918 miles for the second. This little trick was accomplished by stitching together data from several orbits, creating an image that appears to be “pulled back.”

NASA launched the 4,600-pound Suomi in October to remotely sense variations in the Earth’s oceans, continents, and atmosphere and get a better understanding of climate change. It passes directly from pole to pole 14 times a day, imaging 1,865-mile swaths of our planet with each trip.

On board Suomi, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument takes pictures in red, green, and blue wavelengths. For the whole-Earth images, those wavelengths were combined to create a natural color photograph. It is not an exact representation of what an observer sitting in space would see, because particles in the atmosphere scatter short wavelengths of light, and our planet would actually appear more blue-tinged. The photos more accurately portray how the oceans and continents appear from the ground.

Oceanographer Norman Kuring, who compiled the two pictures, said the original image, showing North and Central America, was made as a favor to project scientist James Gleason who was looking for an ocean color image to show in a presentation. Word got out of the striking picture and NASA officials released it on Jan. 25, resulting in 3 million people viewing it in one week.

With the popularity of this first image and requests from the public for another perspective, the agency produced a second image on Feb. 3 showing Africa and the Arabian Peninsula.

The photos follow in the footsteps of NASA’s other great Earth images. The original Blue Marble — one of the most famous pictures of all time — was captured by the crew of Apollo 17 from a distance of 28,000 miles. Since 2002, the agency has stitched together up to 10,000 satellite images to produce other incredible detailed images. One of the most recent, from 2007, had a mind-boggling resolution of 86,400 pixels by 43,200 pixels.

Such pictures have proved time and time again to be among the most-viewed and best-loved NASA photos. What accounts for their enduring popularity?

“My guess is that people know that this is the only place we have to live. When they see an image showing these beautiful blues and greens, it speaks to them,” said Kuring. “This is our home.”

Russian Drill Penetrates 14-Million-Year-Old Antarctic Lake

Update: Russian news agency Ria Novosti has reported that the team penetrated Lake Vostok on Feb. 5, 2012. According to the report, the researchers stopped drilling at a depth of 3,768 meters as they reached the surface of the sub-glacial lake.

After 20 years of drilling, a team of Russian researchers is close to breaching the prehistoric Lake Vostok, which has been trapped deep beneath Antarctica for the last 14 million years.

Wired U.K.Vostok is the largest in a sub-glacial web of more than 200 lakes that are hidden 4 kilometers beneath the ice. Some of the lakes formed when the continent was much warmer and still connected to Australia.

The lakes are rich in oxygen (making them oligotrophic), with levels of the element some 50 times higher than what would be found in your typical freshwater lake. The high gas concentration is thought to be because of the enormous weight and pressure of the continental ice cap.

If life exists in Vostok, it will have to be an extremophile — a life form that has adapted to survive in extreme environments. The organism would have to withstand high pressure, constant cold, low nutrient input, high oxygen concentration and an absence of sunlight.

The conditions in Lake Vostok are thought to be similar to the conditions on Jupiter’s moon Europa and Saturn’s tiny moon Enceladus. In June, NASA probe Cassini found the best evidence yet for a massive saltwater reservoir beneath the icy surface of Enceladus. This all means that finding life in the inhospitable depths of Vostok would strengthen the case for life in the outer solar system.

Back on planet Earth, the team at Vostok are running short on time. Antarctica’s summer will soon end and the researchers need to leave their remote base while they still can. Temperatures will drop as low as -80 degrees Celsius, grounding planes and trapping the team.

They missed their chance last year. “Time is short, however. It’s possible that the drillers won’t be able to reach the water before the end of the current Antarctic summer, and they’ll need to wait another year before the process can continue,” we wrote in January 2011. The drill halted in February.

Meanwhile, Russian engineers are planning to venture into the lake itself, with swimming robots. In the Antarctic summer of 2012 to 2013, they plan to send a robot into the lake to collect water samples and sediments from the bottom. An environmental assessment of the plan will be submitted at the Antarctic Treaty’s consultative meeting in May 2012.

Today's mystery bird for you to identify | @GrrlScientist

Mystery Birds photographed at Lake Washington, Seattle, Washington (USA). [I will identify these birds for you in 48 hours]

Image: Doug Schurman, 22 January 2012 (with permission) [velociraptorize].
Canon 7D with the Canon 400mm f5.6 lens

Question: These common North American mystery birds are strikingly different in size despite having the same colours and patterns. Why? Are these parent birds with one of their chicks? Are they different subspecies or are they two different species? Can you identify the taxonomic family and species for these birds?

The Rules:

1. Keep in mind that people live in zillions of different time zones, and some people are following on their smart phones. So let everyone play the game. Don't spoil it for everyone else by identifying the bird in the first 24 to 36 hours.
2. If you know the mystery bird's identity, answer the accompanying questions and provide subtle ID hints so others know that you know. Your hints may be helpful clues for less experienced players. Keep in mind that some hints may read like "inside jokes" and thus, may discourage others from participating.
3. Describe the key field marks that distinguish this species from any similar ones.
4. Comments that spoil others' enjoyment may be deleted.

The Game:

1. This is meant to be a learning experience where together we learn a few things about birds and about the process of identifying them (and maybe about ourselves, too).
2. Each mystery bird is usually accompanied by a question or two. These questions can be useful for identifying the pictured species, but may instead be used to illustrate an interesting aspect of avian biology, behaviour or evolution, or may be intended to generate conversation on other topics, such as conservation or ethics.
3. Thoughtful comments will add to everyone's enjoyment, and will keep the suspense going until the next teaser is published. Interesting snippets may add to the knowledge of all.
4. Each bird species will be demystified approximately 48 hours after publication.

You are invited to review all of the daily mystery birds by going to their dedicated graphic index page.

If you have bird images, video or mp3 files that you'd like to share with a large and (mostly) appreciative international audience here at The Guardian, feel free to contact me to learn more.

Science Weekly podcast: Transplants and the future of intensive care

This week, we're focusing on some pivotal stories from the history of science and medicine.

First up are human-to-human transplants and intensive care medicine. These are among the greatest successes of post-war medicine, but they also raise some of the most profound ethical questions. Ahead of a discussion at the Royal Institution in London, Kevin Fong, an anaesthetist and physiology lecturer at University College London, and medical historian Richard Barnett came into the studio to discuss how these important medical interventions started and, crucially, where they are heading.

The debates will be held at the Royal Institution on 28 February. "From iron lungs to intensive care", "Hearts to hearts" will be on 15 February.

The Observer's science editor, Robin McKie, was on hand to delve into the secrets of the Piltdown Hoax of 1912. The discovery that the Piltdown Man remains were not all they seemed rocked the scientific establishment of the time, and now a new generation of researchers wants to find out the truth. Who was behind the hoax?

And finally … with Nature and Science voluntarily suspending their publication of studies into bird flu, we ask: should scientific research ever be censored?
