The hypothalamus is a small structure deep in the brain that, among other functions, coördinates sensory inputs—the appearance of a rival, for example—with instinctual behavioral responses. Back in the 1920s, Walter Hess of the University of Zurich (who would win a Nobel in 1949) had shown that if you stuck an electrode into the brain of a cat and electrically stimulated certain regions of the hypothalamus, you could turn a purring feline into a furry blur of aggression. Several interesting hypotheses tried to explain how and why that happened, but there was no way to test them. Like a lot of fundamental questions in brain science, the mystery of aggression didn’t go away over the past century—it just hit the usual empirical roadblocks. We had good questions but no technology to get at the answers.

By 2010, Anderson’s Caltech lab had begun to tease apart the underlying mechanisms and neural circuitry of aggression in their pugnacious mice. Armed with a series of new technologies that allowed them to focus on individual clumps of cells within brain regions, they stumbled onto a surprising anatomical discovery: the tiny part of the hypothalamus that seemed correlated with aggressive behavior was intertwined with the part associated with the impulse to mate. That small duchy of cells—the technical name is the ventromedial hypothalamus—turned out to be an assembly of roughly 5,000 neurons, all marbled together, some of them seemingly connected to copulating and others to fighting.

“There’s no such thing as a generic neuron,” says Anderson, who estimates that there may be up to 10,000 distinct classes of neurons in the brain. Even tiny regions of the brain contain a mixture, he says, and these neurons “often influence behavior in different, opposing directions.” In the case of the hypothalamus, some of the neurons seemed to become active during aggressive behavior, some of them during mating behavior, and a small subset—about 20 percent—during both fighting and mating.

That was a provocative discovery, but it was also a relic of old-style neuroscience. Being active was not the same as causing the behavior; it was just a correlation. How did the scientists know for sure what was triggering the behavior? Could they provoke a mouse to pick a fight simply by tickling a few cells in the hypothalamus?

A decade ago, that would have been technologically impossible. But in the last 10 years, neuroscience has been transformed by a remarkable new technology called optogenetics, invented by scientists at Stanford University and first described in 2005. The Caltech researchers were able to insert a genetically modified light-sensitive gene into specific cells at particular locations in the brain of a living, breathing, feisty, and occasionally canoodling male mouse. Using a hair-thin fiber-optic thread inserted into that living brain, they could then turn the neurons in the hypothalamus on and off with a burst of light.

Optogenetics: Light Switches for Neurons

Anderson and his colleagues used optogenetics to produce a video dramatizing the love-hate tensions deep within rodents. It shows a male mouse doing what comes naturally, mating with a female, until the Caltech researchers switch on the light, at which instant the murine lothario flies into a rage. When the light is on, even a mild-mannered male mouse can be induced to attack whatever target happens to be nearby—his reproductive partner, another male mouse, a castrated male (normally not perceived as a threat), or, most improbably, a rubber glove dropped into the cage.

“Activating these neurons with optogenetic techniques is sufficient to activate aggressive behavior not only toward appropriate targets like another male mouse but also toward inappropriate targets, like females and even inanimate objects,” Anderson says. Conversely, researchers can inhibit these neurons in the middle of a fight by turning the light off, he says: “You can stop the fight dead in its tracks.”

Moreover, the research suggests that lovemaking overrides war-making in the calculus of behavior: the closer a mouse was to consummation of the reproductive act, the more resistant (or oblivious) he became to the light pulses that normally triggered aggression. In a paper published in Biological Psychiatry, titled “Optogenetics, Sex, and Violence in the Brain: Implications for Psychiatry,” Anderson noted, “Perhaps the imperative to ‘make love, not war’ is hard-wired into our nervous system, to a greater extent than we have realized.” We may be both lovers and fighters, with the slimmest of neurological distances separating the two impulses.

Optogenetics and other new techniques mean scientists can begin to pinpoint the function of the thousands of different types of neurons among the roughly 86 billion in the human brain.

No one is suggesting that we’re on the verge of deploying neural circuit breakers to curb aggressive behavior. But, as Anderson points out, the research highlights a larger point about how a new technology can reinvent the way brain science is done. “The ability of optogenetics to turn a largely correlational field of science into one that tests causation has been transformative,” he says.

What’s radical about the technique is that it allows scientists to perturb a cell or a network of cells with exquisite precision, the key to sketching out the circuitry that affects various types of behavior. Whereas older technologies like imaging allowed researchers to watch the brain in action, optogenetics enables them to influence that action, tinkering with specific parts of the brain at specific times to see what happens.

And optogenetics is just one of a suite of revolutionary new tools that are likely to play leading roles in what looks like a heyday for neuroscience. Major initiatives in both the United States and Europe aspire to understand how the human brain—that tangled three-pound curd of neurons, connective tissue, and circuits—gives rise to everything from abstract thought to basic sensory processing to emotions like aggression. Consciousness, free will, memory, learning—they are all on the table now, as researchers use these tools to investigate how the brain achieves its seemingly mysterious effects (see “Searching for the “Free Will” Neuron”).


More than 2,000 years ago, Hippocrates noted that if you want to understand the mind, you must begin by studying the brain. Nothing has happened in the last two millennia to change that imperative—except the tools that neuroscience is bringing to the task.

The history of neuroscience, like the history of science itself, is often a story of new devices and new technologies. ­Luigi Galvani’s first accidental electrode, which provoked the twitch of a frog’s muscle, has inspired every subsequent electrical probe, from ­Walter Hess’s cat prod to the current therapeutic use of deep brain stimulation to treat Parkinson’s disease (approximately 30,000 people worldwide now have electrodes implanted in their brains to treat this condition). The patch clamp allowed neuroanatomists to see the ebb and flow of ions in a neuron as it prepares to fire. And little did Paul Lauterbur realize, when he focused a strong magnetic field on a single hapless clam in his lab at the State University of New York at Stony Brook in the early 1970s, that he and his colleagues were laying the groundwork for the magnetic resonance imaging (MRI) machines that have helped reveal the internal landscape and activity of a living brain.

Growing Neurons: Studying What Goes Wrong

But it is the advances in genetics and genomic tools during the last few years that have truly revolutionized neuroscience. Those advances made the genetic manipulations at the heart of optogenetics possible. Even more recent genome-editing methods can be used to precisely alter the genetics of living cells in the lab. Along with optogenetics, these tools mean scientists can begin to pinpoint the function of the thousands of different types of nerve cells among the roughly 86 billion in the human brain.

Nothing testifies to the value of a new technology more than the number of scientists who rapidly adopt it and use it to claim new scientific territories. As Edward Boyden, a scientist at MIT who helped develop optogenetics, puts it, “Often when a new technology comes out, there’s a bit of a land grab.”

And even as researchers grab those opportunities in genomics and optogenetics, still other advances are coming on the scene. A new chemical treatment is making it possible to directly see nerve fibers in mammalian brains; robotic microelectrodes can eavesdrop on (and perturb) single cells in living animals; and more sophisticated imaging techniques let researchers match up nerve cells and fibers in brain slices to create a three-dimensional map of the connections. Using these tools together to build up an understanding of the brain’s activity, scientists hope to capture the biggest of cognitive game: memory, decision-­making, consciousness, psychiatric illnesses like anxiety and depression, and, yes, sex and violence.

Scientists speculated that if you could smuggle the gene for a light-sensitive protein into a neuron and then pulse the cell with light, you might trigger it to fire. You could turn specific neurons on and off.

In January 2013, the European Commission invested a billion euros in the launch of its Human Brain Project, a 10-year initiative to map out all the connections in the brain. Several months later, in April 2013, the Obama administration announced an initiative called Brain Research through Advanced Innovative Neurotechnologies (BRAIN), which is expected to pour as much as $1 billion into the field, with much of the early funding earmarked for technology development. Then there is the Human Connectome Project, which aims to use electron microscope images of sequential slices of brain tissue to map nerve cells and their connections in three dimensions. Complementary connectome and mapping initiatives are getting under way at the Howard Hughes Medical Institute in Virginia and the Allen Institute for Brain Science in Seattle. They are all part of a large global effort, both publicly and privately funded, to build a comprehensive picture of the human brain, from the level of genes and cells to that of connections and circuits.

Last December, as an initial step in the BRAIN Initiative, the National Institutes of Health solicited proposals for $40 million worth of projects on technology development in the neurosciences. “Why is the BRAIN Initiative putting such a heavy emphasis on technology?” says Cornelia Bargmann, the Rockefeller University neuroscientist who co-directs the planning process for the project. “The real goal is to understand how the brain works, at many levels, in space and time, in many different neurons, all at once. And what’s prevented us from understanding that is limitations in technology.”


Optogenetics had its origins in 2000, in late-night chitchat at Stanford University. There, neuroscientists Karl Deisseroth and Edward Boyden began to bounce ideas back and forth about ways to identify, and ultimately manipulate, the activity of specific brain circuits. Deisseroth, who had a PhD in neuroscience from Stanford, longed to understand (and someday treat) the mental afflictions that have vexed humankind since the era of Hippocrates, notably anxiety and depression (see “Shining Light on Madness”). Boyden, who was pursuing graduate work in brain function, had an omnivorous curiosity about neurotechnology. At first they dreamed about deploying tiny magnetic beads as a way to manipulate brain function in intact, living animals. But at some point during the next five years, a different kind of light bulb went off.

Since the 1970s, microbiologists had been studying a class of light-sensitive molecules known as rhodopsins, which had been identified in simple organisms like bacteria, fungi, and algae. These proteins act like gatekeepers along the cell wall; when they detect a particular wavelength of light, they either let ions into a cell or, conversely, let ions out of it. This ebb and flow of ions mirrors the process by which a neuron fires: the electrical charge within the nerve cell builds up until the cell unleashes a spike of electrical activity flowing along the length of its fiber (or axon) to the synapses, where the message is passed on to the next cell in the pathway. Scientists speculated that if you could smuggle the gene for one of these light-sensitive proteins into a neuron and then pulse the cell with light, you might trigger it to fire. Simply put, you could turn specific neurons in a conscious animal on—or off—with a burst of light.

In 2004, Deisseroth successfully inserted the gene for a light-sensitive molecule from algae into mammalian neurons in a dish. Deisseroth and ­Boyden went on to show that blue light could induce the neurons to fire. At about the same time, a graduate student named Feng Zhang joined Deisseroth’s lab. Zhang, who had acquired a precocious expertise in the techniques of both molecular biology and gene therapy as a high school student in Des Moines, Iowa, showed that the gene for the desired protein could be introduced into neurons by means of genetically engineered viruses. Again using pulses of blue light, the Stanford team then demonstrated that it could turn electrical pulses on and off in the virus-modified mammalian nerve cells. In a landmark paper that appeared in Nature Neuroscience in 2005 (after, Boyden says, it was rejected by Science), Deisseroth, Zhang, and Boyden described the technique. (No one would call it “optogenetics” for another year.)

Neuroscientists immediately seized on the power of the technique by inserting light-sensitive genes into living animals. Researchers in Deisseroth’s own lab used it to identify new pathways that control anxiety in mice, and both ­Deisseroth’s team and his collaborators at Mount Sinai Hospital in New York used it to turn depression on and off in rats and mice. And Susumu Tonegawa’s lab at MIT recently used optogenetics to create false memories in laboratory animals.

When I visited Boyden’s office at MIT’s Media Lab last December, the scientist called up his favorite recent papers involving optogenetics. In a rush of words as rapid as his keystrokes, Boyden described second-generation technologies already being developed. One involves eavesdropping on single nerve cells in anesthetized and conscious animals in order to see “the things roiling underneath the sea of activity” within a neuron when the animal is unconscious. Boyden said, “It literally sheds light on what it means to have thoughts and awareness and feelings.”

Scientists often employ words like “surprising” and “unexpected” to characterize recent results, reflecting the impact optogenetics has had on the understanding of psychiatric illnesses.

Boyden’s group had also just sent off a paper reporting a new twist on optogenetics: separate, independent neural pathways can be perturbed simultaneously with red and blue wavelengths of light. The technique has the potential to show how different circuits interact with and influence each other. His group is also working on “insanely dense” recording probes and microscopes that aspire to capture whole-brain activity. The ambitions are not modest. “Can you record all the cells in the brain,” he says, “so that you can watch thoughts or decisions or other complex phenomena emerge as you go from sensation to emotion to decision to action site?”

Brain Mapping: Charting the Information Superhighways

A few blocks away, Feng Zhang, who is now an assistant professor at MIT and a faculty member at the Broad Institute, listed age-old neuroscience questions that might now be attacked with the new technologies. “Can you do a memory upgrade and increase the capacity?” he asked. “How are neural circuits genetically encoded? How can you reprogram the genetic instructions? How do you fix the genetic mutations that cause miswiring or other malfunctions of the neural system? How do you make the old brain younger?”

In addition to helping to invent optogenetics, Zhang played a central role in developing a gene-editing technique called CRISPR (see “10 Breakthrough Technologies: Genome Editing,” May/June). The technology allows scientists to target a gene—in neurons, for example—and either delete or modify it. If it’s modified to include a mutation known or suspected to cause brain disorders, scientists can study the progression of those disorders in lab animals. Alternatively, researchers can use CRISPR in the lab to alter stem cells that can then be grown into neurons to see the effects.


Back at Stanford, when he’s not seeing patients with autism spectrum disorders or depression in the clinic, Deisseroth continues to invent tools that he and others can use to study these conditions. Last summer, his lab reported a new way for scientists to visualize the cables of nerve fibers, known as “white matter,” that connect distant precincts of the brain. The technique, called Clarity, first immobilizes biomolecules such as protein and DNA in a plastic-like mesh that retains the physical integrity of a postmortem brain. Then researchers flush a kind of detergent through the mesh to dissolve all the fats in brain tissue that normally block light. The brain is rendered transparent, suddenly exposing the entire three-­dimensional wiring pattern to view.

Together, the new tools are transforming many conventional views in neuroscience. For example, as Deisseroth noted in a review article published earlier this year in Nature, optogenetics has challenged some of the ideas underlying deep brain stimulation, which has been widely used to treat everything from tremors and epilepsy to anxiety and obsessive-­compulsive disorder. No one knows just why it works, but the operating assumption has been that its therapeutic effects derive from electrical stimulation of very specific brain regions; neurosurgeons exert extraordinary effort to place electrodes with the utmost precision.

In 2009, however, Deisseroth and colleagues showed that specifically stimulating the white matter, the neural cables that happen to lie near the electrodes, produced the most robust clinical improvement in symptoms of Parkinson’s disease. In other words, it wasn’t the neighborhood of the brain that mattered so much as which neural highways happened to pass nearby. Scientists often employ words like “surprising” and “unexpected” to characterize such recent results, reflecting the impact that optogenetics has had on the understanding of psychiatric illness.

In the same vein, Caltech’s Anderson points out that the public and scientific infatuation with functional MRI studies over the last two decades has created the impression that certain regions of the brain act as “centers” of neural activity—that the amygdala is the “center” of fear, for example, or the hypothalamus is the “center” of aggression. But he likens fMRI to looking down on a nighttime landscape from an airplane at 30,000 feet and “trying to figure out what is going on in a single town.” Optogenetics, by contrast, has provided a much more detailed view of that tiny subdivision of cells in the hypothalamus, and thus a much more complex and nuanced picture of aggression. Activating specific neurons in that little town can tip an organism to make war, but activating the neurons next door can nudge it to make love.

The new techniques will give scientists the first glimpses of human cognition in action—a look at how thoughts, feelings, forebodings, and dysfunctional mental activity arise from the neural circuitry and from the activity of particular types of cells. Researchers are just beginning to gain these insights, but given the recent pace of technology development, the picture might emerge sooner than anyone dreamed possible when the light of optogenetics first flickered on a few years ago.

The Promise and Perils of Manipulating Memory PDF Print E-mail

When it comes to the study of memory, we might be living in something of a golden age. Researchers are exploring provocative questions about what memory fundamentally isand how it might be manipulated. Some scientists are tweaking the brains of lab rats in order to implant false memories or remove specific memories. Others are looking into how memory might be enhanced. Such research often sounds creepy, but it could lead to ways of staving off dementia, neutralizing post-traumatic stress disorder, reducing anxiety, treating depression, or curbing addiction.

Much of this work is possible because neuroscientists have realized that memory is more plastic than previously thought. Think of something that you did long agoon a sunny afternoon when you were a child, let’s say. Does your brain rummage around for that memory, show it to you, and put it back intact, as you might do with a photograph in a trunk in the attic? For decades, the prevailing answer was essentially yesthat strong memories were “consolidated” in the brain and remained static. But it now appears the opposite is true: every time you remember something, your brain rewrites or “reconsolidates” the memory. Your memory of any sunny day in your childhood is merely a version of the last time you thought about it.

Among the stunning implications is that intervening in the reconsolidation process can alter a memory and change how it feels. Some of the most intriguing research on this idea has been led by Joseph LeDoux, a neuroscientist who has been working since the 1970s to investigate how processes in the brain generate emotions. In recent years, he and colleagues have investigated whether giving people an antianxiety drug as they recall a traumatic experience can reduce the dread they feel upon further recollections. If it works, it could be one of many opportunities for reshaping memory, as LeDoux told MIT Technology Review’s deputy editor, Brian Bergstein, in his NYU office.

Giving people a pill as they reconsolidate a troubling memory sounds like an elegant treatment for PTSD and other disorders. How well has the research progressed?

The idea is still viable. The drug that’s going to do the trick in humanswe don’t yet know what it is.

Why not the antianxiety drug propranolol, which has been used in several experiments?

We know this thing works very well in rats. [In humans] there’s been some success, but it doesn’t seem that’s actually going to be a very robust solution.

What are the prospects for improving the memory of people with dementiaor any of us, for that matter?

The issue you get at whenever you’re dealing with a memory failure of any kind is: is the problem an inability to retrieve a memory that’s there, or is it that the memory is no longer there and by no means could you retrieve it? And it’s definitely the case that we have retrieval problems, right? You can’t remember something, you kind of know it’s there, and then a couple of hours later it pops up. There is stuff in our brain that we can’t easily retrieve. I think that’s where there’s hope. You can do things that would facilitate the retrieval process.

What might that be?

The simplest idea would be that it’s a problem of low arousal in the brain. We know that emotionally arousing situations are more likely to be remembered than mundane ones. A big part of the reason for this is that in significant situations chemicals called neuromodulators are released, and they enhance the memory storage process. The brain is more alert and attentive. All the spokes are working and all the gears are oiled.

So could we develop memory vitamins that offer that same boost?

[The effects of the neuromodulators] can be mimicked with drugs that do the same thing. Or if you want to remember something, put the information in a significant context. In other words, make it meaningful by thinking of it in a way that adds some positive or negative charge, or by doing something that increases your level of arousal—exercise, for example.

Would a memory prosthetic be possiblesomething put into the brain to restore lost memories in someone with dementia or a brain injury?

DARPA [the U.S. military’s R&D agency] seems to be going full steam ahead on these kinds of technologies. What they plan to do is put chips in [the brain]. It would be like a prosthesis—instead of moving your arm, you’re fixing memory. I have no idea how they would achieve that.

We don’t know the route to get there?

I don’t know the route.

Memory is, first of all, not in one spot—it’s distributed across probably multiple brain areas, many millions of synapses in those brain areas. So I don’t know how you reconfigure it, fix it. I don’t know how you regenerate the right patterns of connectivity. I don’t think you could restore lost memories. But what you might conceivably do is restore some ability to store new memories.

“You can’t remember something, you kind of know it’s there, and then a couple of hours later it pops up. There is stuff in our brain that we can’t easily retrieve. I think that’s where there’s hope. You can do things that would facilitate the retrieval process.”

Messing with memory is a huge deal. It goes to the core of who we are. Treating PTSD would be wonderful, but isn’t it also possible to make people artificial Pollyannas?

Or fearless monsters. There’s always going to be ethical implications. But we’ll just have to sort that out.

When we first published this work [on reconsolidation], someone wrote a commentary in the New York Times saying, “Let’s say you were a Holocaust survivor. You lived 50 years with these awful memories, and all of a sudden you’re erasing memories of the Holocaust. What would that do to your personality? It’s who you are now.” [After further research], the conclusion that we came up with is that a patient and therapist would have to slowly chip away at a memory to a level they were comfortable with. [And] the research so far suggests it reduces the zing, takes the emotional valence out of the situation, rather than erases the memory itself.

The other side of that is you can also intensify memories. So we did studies in rats where we give them propranolol, and that weakens the memory. But if you give them ­isoproterenol [which has the opposite effect on the brain’s neurostimulators], the memory is now stronger. If you have some way to strengthen memory after retrieval, it could be stronger and better.

What’s a situation in which people would want to do that?

In general, people who have sluggish memories, they’re not forming memories very well. Were they to be on a low dose of isoproterenol, they might get a little extra boost.

The other idea is that we might be able to give people positive experiences and a shot of isoproterenol, and store those instead of negative experiences.

You could build up more positive memories in them?

Right, right.

I imagine that could be useful in helping people struggling with depression.

And as far as I know it’s never been done. It’s doable.

So why hasn’t it been done?

Well, you know, I had the idea a while ago, and then I kind of forgot about it. And now the memory of itmaybe I’ll think about doing something. [He laughs.]

New Eruption at Piton de la Fournaise on Reunion Island PDF Print E-mail

The June 21, 2014 eruption of Piton de la Fournaise on Reunion Island.

The June 21, 2014 eruption of Piton de la Fournaise on Reunion Island. (video capture).

I guess the competition in Group E just got more interesting. Piton de la Fournaise, located on Reunion Island in the Indian Ocean, had its first eruption (see above) since 2010. The eruption is behaving as most do at the shield volcano over the Reunion hotspot, with fast moving lava flows over the barren terrane. You can see some video of the eruption, showing the fissure and the branching lava flows heading down slope (see below). The lavas at Piton de la Fournaise are lower viscosity than you find at similar eruptions at another hotspot volcano, Kilauea. That’s because the lava is more alkaline, where the addition of Na, K and Ca into the magma keeps it from forming chains of silica as easily. This means the viscosity remains lower for longer and producing those fast moving pahoehoe flows. Luckily this eruption is in a very remote part of the volcano, so there is little-to-no threat from the flows, unlike the eruption in 2007.

The eruption itself started in the early morning hours on June 21 from the southeastern side of the main summit crater. There had been 10 days of precursory signs that an eruption was in the works, with higher gas emissions and seismicity, along with a red glow in the area very recently. Unfortunately this current eruption is not occurring in view of any of the webcams pointed at the volcano.

Volcano World Cup: Group E PDF Print E-mail

The Volcano World Cup rolls on. Remember, vote in Group A, Group B, Group C and Group D.

Today we tackle Group E: Ecuador, France, Honduras, and Switzerland.

Ecuador: If any country has a true cakewalk to the Round of 16, it might be Ecuador. Their competition can’t hold a candle to the multitude of active volcanoes in Ecuador that include Tungurahua (see below), El Reventador, Sangay and Guagua Pichincha. All of those volcanoes have erupted since the turn of the century, so it doesn’t include one volcano that may have produced one of the largest eruptions of the last 2,000 years (Chimborazo) or the famous Cotopaxi. Hard to envision a way that Ecuador doesn’t cruise to the next round.

France: Actually, you might not guess it at first, but France does a good job to hold its own with volcanoes. Continental France is fairly volcanically quiet, but it does boast some regions of potential activity. Most importantly, the Chaîne des Puys lava domes (see below) formed at ~4040 BC, meaning they are very much still capable of another eruption. France’s greater empire does contain a fair amount of volcanoes as well, stretch across islands in the Caribbean, Pacific and Indian Oceans, including Piton de la Fournaise (which incidentally started erupting this morning) and the infamous Peleé that killed over 30,000 people in 1902.

Honduras: Although much of Central America is volcanically active, the number of volcanoes that have erupted in the last 10,000 years in Honduras is quite low. There are 4 volcanoes listed in the Smithsonian/USGS Global Volcanism Program’s database, but most of them show signs they have not been active for quite some time. Isla el Tigre (see below) is one of those weathered volcanic edifices in Honduras located just off the coast in the Gulf of Fonseca.

Switzerland: Being smack dab in the middle of Europe, it isn’t surprising that Switzerland is lacking in any active volcanoes. However, intercalated in the rocks of the Alps are volcanic deposits that date back hundreds of millions of years, like the chunk of rhyolite below. This rock betrays the volcanic past of Switzerland.

What to Expect From the Wild New Harry Potter Ride, ‘Escape From Gringotts’ PDF Print E-mail

The new addition to the Harry Potter Theme Park, Daigon Alley, was open to the media and VIP's on Thursday, June 19, 2014.

ORLANDO, Florida — Escape From Gringotts is one hell of a ride, a technologically awesome thrill that puts you in the middle of Harry Potter’s dramatic break in and escape from the wizarding world’s Fort Knox.

The centerpiece of the new Diagon Alley expansion to the fantastic Wizarding World of Harry Potter theme park sends you on a daring dash through the bank’s underground vaults. You spin and whirl down the track, riding past massive 3-D projection screens (yes, you wear glasses) on which the heroes and villains of J.K.K. Rowling’s epic series act out the story.

But it is much more than a roller coaster, or even a motion-simulation-in-front-of-a-big-screen ride experience. Since you’re actually riding a kinetic, fast-moving cart that dips and makes hairpin turns, it feels more like you’re actually part of the action projected on the screen. The combination of real and special FX is powerful.

When it works.

WIRED was lucky enough to experience the ride before it went kaput during this week’s media blitz. After a series of glitches—including one that left us stranded on the tracks for 10 minutes—park brass shut the ride down early Wednesday evening, and didn’t run it at all Thursday. That raises questions about whether Universal Studios will have things sorted out before the July 8 opening.

Much like “Harry Potter and the Forbidden Journey,” which wound would-be riders through all the halls of Hogwarts before they got onto the ride, the line to get into Gringotts is entertaining all by itself. You begin by walking into the main lobby of the bank, which is situated right at the crossroads of the various streets that make up Diagon Alley. The buildings spill out at all angles except right ones, filled top to bottom with intricately lettered signs and lively window displays, every detail painstakingly true to the source material. It’s like stepping onto the movie set.

In the lobby are remarkable animatronic goblins, the bank’s tellers, that are—what’s the word for it?—freaky. They’ll occasionally look up from their work in the bank’s ledgers and stare at you wordlessly. (If you want to actually interact with a goblin, there’s one in the Gringotts currency exchange building down the street that will actually answer questions that are posed to it.)

Past the lobby, a long hallway filled with desks and other office furniture has copies of the Daily Prophet, the wizarding world’s newspaper, complete with magical moving photographs. Further down the way you’ll enter the office of Bill Weasley, older brother of Harry’s ginger pal Ron. We don’t actually see much of Harry, Ron and Hermione on the Gringotts ride, come to think of it. But Bill gets more screen time here in a hologram sequence than he ever did in all eight films.


It’s okay if the goblins unsettle you a little. Ty Wright/WIRED

After this, an “elevator” takes you down, down, down without actually moving you anywhere at all, a combination of clever video and hydraulic effects. Then you’re ready to get on the cart and ride it into the unknown.

For all the flash, Gringotts didn’t feel as thrilling as “Forbidden Journey,” which has similar effects and even flips you right upside down at some points. And as fearsome as the video projections of Bellatrix Lestrange (Helena Bonham Carter) and Lord Voldemort (Ralph Fiennes) are at the climax of “Gringotts,” the Dementor attacks in “Forbidden Journey” are much scarier. (Maybe because you’re upside down.) But Gringotts’ gentler nature carries with it a significantly lower height requirement, meaning more kids can join in the excitement.

Google Reveals How the Android Wear UI Will Work PDF Print E-mail

When Google announced Android Wear back in March, it illustrated the company’s seriousness about the wearable game. Since then, Google has dropped bread crumbs, slowly painting us a bigger picture of what’s to come with its mobile OS. A new video from the company, released just days before its big I/O conference, outlines some of the main interaction considerations for developers who will be building apps for the inevitable wave of new wrist worn gadgets.

The big takeaway? Interacting with our gadgets is about to get a whole lot simpler. Android Wear’s banner claim is that its interface will free us from the time sucking grid of icons on our smartphones. Instead, the interface will be glanceable; requiring users to engage far less time and attention to get the information they’re looking for.

Android Wear’s banner claim is that its interface will free us from the time sucking grid of icons on our smartphones. Instead, the interface will be glanceable.

Here’s a quick look at how they’re doing it: The first thing you notice about the Android Wear interface is how little there is to notice. In the video’s example of the home screen, you see the time, weather and a “G” icon that will help you navigate to voice or text search. Users simply have to hit the button and say “Ok Google” to make any voice command available.


But it’s not a one-way conversation. Google’s depth of data makes it easy for Android Wear to build a smart context around each user, allowing wearables to know what’s important to a person and when it’s important. For example, based on your calendar or inbox your smartwatch could notify you a few hours before your flight and prompt you to check in.

Another important feature is device-to-device communication. Any notification you get on your phone, you’ll get on your wearable, too. Where a smartwatch diverges from the phone is how it presents that information. Android Wear relies on stacks, which allows developers to bundle multiple notifications together like an inbox, while pages allow more than one glanceable screen of information at a time for one notification. Think of this like flipping through a tiny ebook of notifications. You can combine stacks and pages and reply to any notification through voice activation.

The video covers pretty high-level stuff, but with LG and Motorola already building their own Android Wear smartwatches, you can bet it won’t be long before we get a proper look at what this OS is capable of.

One of F1′s Most Dangerous Tracks Is Back PDF Print E-mail

Infinit Red Bull Racing driver Daniel Ricciardo takes a lap of the Red Bull Ring during a practice session. F1 returns to Austria for the first time since 2003 at the track, which Red Bull co-founder Dietrich Mateschitz bought in 2004.

This weekend, Formula 1 racing returns to a course that was once among the most dangerous in the world. The sport has in recent years focused on expanding beyond its traditional base in Europe, adding races in China, Singapore, Korea and, later this year, Russia. But the newest race on the calendar is in the heart of Europe: Austria, home to some of the sport’s all-time greats.

The country has a rich racing tradition—F1 drivers like Jochen Rindt, Niki Lauda, and Gerhard Berger are all Austrian—and the A1-Ring in particular saw great duels like the epic fight between Michael Schumacher and Mika Hakkinen in 1998.

That said, the track in Spielberg was once among the most dangerous in the sport. Elevation changes, tight turns, and small runoff areas made for difficult driving with little margin for error. In August 1975, accomplished driver Mark Donahue died after a crash there created a blood clot in his head. A track marshall was also killed in that crash, the Lewiston Evening Journal reported at the time. The 1987 Austrian Grand Prix had to be stopped twice due to crashes on the pit straight, and Stefan Johansson hit a deer during qualifying that year.

The track, which Red Bull co-founder Dietrich Mateschitz bought in 2004 and renamed the Red Bull Ring, first hosted the championship in 1970, when it was called the Österreichring. Racing there stopped after 1987, when officials finally deemed the course too narrow and too dangerous. F1 track guru Herman Tilke redesigned the track and it returned to F1 in 1997 as the A1-Ring. Schumacher set the lap record of 1:08.337 during the track’s most recent F1 race in 2003.

Mateschitz stepped in the following year, and Red Bull started a €70 million renovation that included a new paddock and grandstands. Racing resumed in 2011.

The new track is just 4.326 kilometers (2.688 miles) long, making it one of the shorter circuits on the calendar. It’s got 10 corners and four straightaways, which should make for some fast laps. Four turns offer passing opportunities, and 60 meters of altitude change (it’s the Alps, after all) will add an extra challenge.

The Red Bull Ring has the same layout as A1, but feels far more commercial. Gone are the corners named after legendary drivers, named instead for corporate sponsors. Turn six, for example, is no longer named for Austrian F1 ace Niki Lauda (now non-executive chairman of Mercedes F1) is named for German tool manufacturer Würth. That said, turn eight, the track’s fastest, still bears the name of F1 racer Jochen Rindt.

The name changes are kind of a bummer, but won’t matter once the drivers start the 71-lap race on Sunday. And though it might be Red Bull’s party, Mercedes plans to crash it. Drivers Lewis Hamilton and Nico Rosberg topped Friday’s practice sessions, while both Red Bull drivers were more than a second behind.

The Amazing Micro-Engineered, Water-Repelling Surface That Lives Outside My Window PDF Print E-mail

See how the water drop bounces off the leaf instead of splashing?

If the water hits the leaf harder, it’ll splash. But it still doesn’t wet the surface.

Here you can watch the water drops merge into one big, wobbly drop.

So how does this leaf  repel water?

To understand this, we first need to know what it means to get wet. Since water molecules attract each other, a blob of water wants to shrink inwards. That’s why a water blob floating in space is round, like a sphere (it’s the most ‘shrunken-in’ shape). But down here on Earth, water isn’t floating in mid-air. It’s sitting on some surface, like your table, your bathtub, or a leaf. This surface pulls down on the water, and squishes the sphere into a pancake. So it looks more like this.


Aatish Bhatia

In fact, you can measure just how ‘wettable’ a surface is by calculating its contact angle.


Aatish Bhatia

The more a surface attracts the water, the more it squishes the ball into a pancake, and the wetter the surface.


Hydrophilic (water-loving) surfaces squish the water ball into a pancake. Aatish Bhatia

On the other hand, hydrophobic (water-hating) surfaces attract the water less, so the drop is more round.


Aatish Bhatia

And then you have superhydrophobic surfaces, like Never Wet, which barely attract the water at all. On these surfaces, water drops are almost spherical. It’s nearly impossible to get these surfaces wet – the water just rolls off them.


Aatish Bhatia

To find out what’s going on with our leaf, we need to measure its contact angle. Janine put a tiny drop of water on the leaf.

plume poppy contact angle mod

Janine Nunes & Aatish Bhatia

BOOM. The contact angle works out to about 175 degrees. The leaf is extremely water repellent – it’s superhydrophobic.

But how does a leaf become superhydrophobic? The trick to this, Janine explained, is that the water isn’t really sitting on the surface. A superhydrophobic surface is a little like a bed of nails. The nails touch the water, but there are gaps between these nails. So there’s fewer points of contact, which means the surface can’t tug on the water as much, and so the drop stays round.


To get superhydrophobic, a drop must lie on a surface that looks like a bed of nails.  ZanderZ / Wikimedia Commons (Public Domain)

If this explanation is correct, then the surface of the plume poppy’s leaf must be coated in tiny needles. To find out, we stuck one of these leaves inside an electron microscope (didn’t I tell you she has access to the coolest toys? I wasn’t lying.)

And, just as we expected, we saw this field of tiny wax needles, each needle just a few microns in length!

topside leaf_2043X

Janine Nunes & Aatish Bhatia

Here’s another look at these tiny spikes. You can see the ripples on the leaf behind it.

topside leaf_2429X

Janine Nunes & Aatish Bhatia

Zooming in further…

topside leaf_8171X

Janine Nunes & Aatish Bhatia

The water drops are suspended on these ultra-microscopic wax needles, and that keeps it from wetting the surface.

Next, we looked at the underside of this leaf with the microscope. We’d noticed earlier that the underside of the leaf was also superhydrophobic, and you could see it was covered with tiny hair-like filaments. But we were blown away with what we saw through the microscope.

underside leaf_94X

Tiny hair-like filaments grow out from the veins under the leaf.  Janine Nunes & Aatish Bhatia

Let’s take a closer look at those fibers.

underside leaf_412X

Janine Nunes & Aatish Bhatia

At this scale, they look like claws reaching out from the veins. To give you a sense of scale, each of these fibers is about as thick as a regular human hair. Now let’s land on one of them.

underside leaf_4270X

Janine Nunes & Aatish Bhatia

Once again, you see a fine mesh of tiny, ultra-microscope wax needles coating each of these fibers, each needle being only a few microns in length. This ability to touch without really touching, by resting the water on a bed of nails, is the secret to the incredible water-repelling powers of this leaf.

There’s one last thing I wanted to know. Why has this plant, and so many others, evolved this incredible ability to keep water at bay? One common explanation is that this allows the leaves to clean themselves. You see, as water rolls around on a superhydrophobic surface, it scoops up dirt and sand with it. Here’s Janine demonstrating this neat self-cleaning property of the leaf with genuine Jersey Shore (TM) sand.

However, I’m not sure that I buy this explanation. Why would a plant evolve a method that cleans the under-side of its leaves? Maybe it produces the wax for some other reason, and as an accidental benefit, this wax just happens to keep the leaves clean? Is there a clear evolutionary advantage for these leaves to be superhydrophobic? I don’t know the answer, but I’d love to find out. If you have any leads, drop me a note in the comments.

Oh, and when something interesting catches the corner of your eye, don’t forget to stop and check it out.


A big thanks to Janine Nunes and Howard Stone’s lab at Princeton U. for indulging me with their time and sharing their equipment. This post wouldn’t have been possible without their extensive resources and immense help.

And a shoutout to my colleague Jaclyn for identifying the plant that no-one else could!

Too-smart Nest smoke detectors back on the shelf PDF Print E-mail


Google's Nest smart smoke alarms, which had to be pulled from the shelves after sensors worked too well, are now back on sale at a lower price -- without the features that caused safety concerns.

"We're very pleased that Nest Protect is once again available to customers," Nest marketing chief Doug Sweeny said in a blog post. "And now, the price is $99 to make it accessible to as many people as possible."

The smart gadget, which is Web-connected and part of the Internet of Things (IoT) movement, combines a smoke detector and carbon monoxide monitor. Previously, the gadget cost $129, and could be controlled by hand gestures instead of users being required to get up close to the ceiling and punch buttons to control the smoke alarm.

However, the sensors worked too well -- and it was discovered that random hand gestures could accidentally turn the alarm's silent feature on.

An over-the-air patch was issued to existing models to disable the feature, but new alarms were also taken off the shelves by Nest until the software fix was applied.

Nest was acquired in January by Google for $3.2 billion. In addition to the smoke detector range, Nest also offers a smart thermostat which can be controlled through mobile devices.
