The Hawaiian island of Kauai may not have any spewing lava, but hikers along the magnificent Napali coast have brought their own volcanic action recently, violently hollowing their innards amid the gushing waterfalls and deeply carved valleys.

Between August and early September, at least 50 hikers fell ill with norovirus along the famed Kalalau Trail, which has been closed since September 4 for a deep cleaning. The rugged 11-mile trail runs along the northwest coast of the island, giving adventurers breathtaking views of stunning sea cliffs and Kauai's lush valleys. It's situated just north of Waimea Canyon State Park, also known as the Grand Canyon of the Pacific.

"It’s one of the most beautiful places in the world. I feel really fortunate to be able to be there, and appreciate and respect that land,” one hiker who fell ill in late August told The Washington Post. "My guts exploding all over that land was not what I wanted to do at all."

Neuralink’s ‘breakthrough device’ clearance from FDA does not mean it has cured blindness

17 September 2024 at 23:12

Neuralink, the Elon Musk-owned brain-computer interface company, on Tuesday received “breakthrough device” clearance from the FDA. But this does not mean the outfit has developed a cure for blindness, no matter what Musk might say. The breakthrough devices program at the FDA is a voluntary program that developers can apply to that, if granted, “offers […]

The Boar's Head deli-meat plant at the epicenter of a nationwide Listeria outbreak that killed nine people so far harbored the deadly germ in a common area of the facility deemed "low risk" for Listeria. Further, it had no written plans to prevent cross-contamination of the dangerous bacteria to other products and areas. That's according to a federal document newly released by Boar's Head.

On Friday, the company announced that it is indefinitely closing that Jarratt, Virginia-based plant and will never again produce liverwurst—the product that Maryland health investigators first identified as the source of the outbreak strain of Listeria monocytogenes. The finding led to the recall of more than 7 million pounds of Boar's Head meat. The Jarratt plant, where the company's liverwurst is made, has been shuttered since late July amid the investigation into how the outbreak occurred.

In the September 13 update, Boar's Head explained that "our investigation has identified the root cause of the contamination as a specific production process that only existed at the Jarratt facility and was used only for liverwurst. With this discovery, we have decided to permanently discontinue liverwurst."

Here’s why you shouldn’t freak out about lead in your cinnamon

Consumer Reports on Thursday reported the concentration of lead it found in 36 ground cinnamon products, leading to a round of startling headlines. The testing is particularly nerve-racking given that it closely follows the tragic poisoning of at least 519 US children, who were exposed to extremely high levels of lead from purposefully tainted cinnamon in applesauce snack pouches.

With that horrifying event in mind, parents are likely primed to be alarmed by any other lead findings in cinnamon. So, how concerning were the concentrations Consumer Reports found? And does one need to strictly adhere to the limits the organization recommends? By my calculations, not very and probably not. It's really not an alarming report.

Similar to the outlet's chocolate testing before it, the lead concentrations found in cinnamons were largely within standard ranges. In all, the report is more of a reminder that trace amounts of heavy metals are present in various common foods. And such watchdog testing can play a crucial role in keeping consumers safe, especially with underfunded and underpowered regulators.

Neuroscientists and architects are using this enormous laboratory to make buildings better

13 September 2024 at 11:00

Have you ever found yourself lost in a building that felt impossible to navigate? Thoughtful building design should center on the people who will be using those buildings. But that’s no mean feat.

It’s not just about navigation, either. Just think of an office that left you feeling sleepy or unproductive, or perhaps a health center that had a less-than-reviving atmosphere. A design that works for some people might not work for others. People have different minds and bodies, and varying wants and needs. So how can we factor them all in?

To answer that question, neuroscientists and architects are joining forces at an enormous laboratory in East London—one that allows researchers to build simulated worlds. In this lab, scientists can control light, temperature, and sound. They can create the illusion of a foggy night, or the tinkle of morning birdsong.

And they can study how volunteers respond to these environments, whether they be simulations of grocery stores, hospitals, pedestrian crossings, or schools. That’s how I found myself wandering around a fake art gallery, wearing a modified baseball cap with a sensor that tracked my movements.

I first visited the Person-Environment-Activity Research Lab, referred to as PEARL, back in July. I’d been chatting to Hugo Spiers, a neuroscientist based at University College London, about the use of video games to study how people navigate. Spiers had told me he was working on another project: exploring how people navigate a lifelike environment, and how they respond during evacuations (which, depending on the situation, could be a matter of life or death).

For their research, Spiers and his colleagues set up what they call a “mocked-up art gallery” within PEARL. The center in its entirety is pretty huge as labs go, measuring around 100 meters in length and 40 meters across, with 10-meter-high ceilings in places. There’s no other research center in the world like this, Spiers told me.

The gallery setup looked a little like a maze from above, with a pathway created out of hanging black sheets. The exhibits themselves were videos of dramatic artworks that had been created by UCL students.

When I visited in July, Spiers and his colleagues were running a small pilot study to trial their setup. As a volunteer participant, I was handed a numbered black cap with a square board on top, marked with a large QR code. This code would be tracked by cameras above and around the gallery. The cap also carried a sensor, transmitting radio signals to devices around the maze that could pinpoint my location within a range of 15 centimeters.

At first, all the volunteers (most of whom seemed to be students) were asked to explore the gallery as we would any other. I meandered around, watching the videos, and eavesdropping on the other volunteers, who were chatting about their research and upcoming dissertation deadlines. It all felt pretty pleasant and calm.

That feeling dissipated in the second part of the experiment, when we were each given a list of numbers, told that each one referred to a numbered screen, and informed that we had to visit all the screens in the order in which they appeared on our lists. “Good luck, everybody,” Spiers said.

Suddenly everyone seemed to be rushing around, slipping past each other and trying to move quickly while avoiding collisions. “It’s all got a bit frantic, hasn’t it?” I heard one volunteer comment as I accidentally bumped into another. I hadn’t managed to complete the task by the time Spiers told us the experiment was over. As I walked to the exit, I noticed that some people were visibly out of breath.

The full study took place on Wednesday, September 11. This time, there were around 100 volunteers (I wasn’t one of them). And while almost everyone was wearing a modified baseball cap, some had more complicated gear, including EEG caps to measure brainwaves, or caps that use near-infrared spectroscopy to measure blood flow in the brain. Some people were even wearing eye-tracking devices that monitored which direction they were looking.

“We will do something quite remarkable today,” Spiers told the volunteers, staff, and observers as the experiment started. Taking such detailed measurements from so many individuals in such a setting represented “a world first,” he said.

I have to say that being an observer was much more fun than being a participant. Gone was the stress of remembering instructions and speeding around a maze. Here in my seat, I could watch as the data collected from the cameras and sensors was projected onto a screen. The volunteers, represented as squiggly colored lines, made their way through the gallery in a way that reminded me of the game Snake.

The study itself was similar to the pilot study, although this time the volunteers were given additional tasks. At one point, they were given an envelope with the name of a town or city in it, and asked to find others in the group who had been given the same one. It was fascinating to see the groups form. Some had the names of destination cities like Bangkok, while others had been assigned fairly nondescript English towns like Slough, made famous as the setting of the British television series The Office. At another point, the volunteers were asked to evacuate the gallery from the nearest exit.

The data collected in this study represents something of a treasure trove for researchers like Spiers and his colleagues. The team is hoping to learn more about how people navigate a space, and whether they move differently if they are alone or in a group. How do friends and strangers interact, and does this depend on whether they have certain types of material to bond over? How do people respond to evacuations—will they take the nearest exit as directed, or will they run on autopilot to the exit they used to enter the space in the first place?

All this information is valuable to neuroscientists like Spiers, but it’s also useful to architects like his colleague Fiona Zisch, who is based at UCL’s Bartlett School of Architecture. “We do really care about how people feel about the places we design for them,” Zisch tells me. The findings can guide not only the construction of new buildings, but also efforts to modify and redesign existing ones.

PEARL was built in 2021 and has already been used to help engineers, scientists, and architects explore how neurodivergent people use grocery stores, and the ideal lighting to use for pedestrian crossings, for example. Zisch herself is passionate about creating equitable spaces—particularly for health and education—that everyone can make use of in the best possible way.

In the past, models used in architecture have been developed with typically built, able-bodied men in mind. “But not everyone is a 6’2″ male with a briefcase,” Zisch tells me. Age, gender, height, and a range of physical and psychological factors can all influence how a person will use a building. “We want to improve not just the space, but the experience of the space,” says Zisch. Good architecture isn’t just about creating stunning features; it’s about subtle adaptations that might not even be noticeable to most people, she says.

The art gallery study is just the first step for researchers like Zisch and Spiers, who plan to explore other aspects of neuroscience and architecture in more simulated environments at PEARL. The team won’t have results for a while yet. But it’s a fascinating start. Watch this space.

Brain-monitoring technology has come a long way, and tech designed to read our minds and probe our memories is already being used. Futurist and legal ethicist Nita Farahany explained why we need laws to protect our cognitive liberty in a previous edition of The Checkup.

Listening in on the brain can reveal surprising insights into how this mysterious organ works. One team of neuroscientists found that our brains seem to oscillate between states of order and chaos.

Last year, MIT Technology Review published our design issue of the magazine. If you’re curious, this piece on the history and future of the word “design,” by Nicholas de Monchaux, head of architecture at MIT, might be a good place to start

Design covers much more than buildings, of course. Designers are creating new ways for users of prosthetic devices to feel more comfortable in their own skin—some of which have third thumbs, spikes, or “superhero skins.”

Achim Menges is an architect creating what he calls “self-shaping” structures with wood, which can twist and curve with changes in humidity. His approach is a low-energy way to make complex curved architectures, Menges told John Wiegand.

High Doses of ADHD Meds Linked to Increased Psychosis Risk

12 September 2024 at 14:57
This shows pills and a head.Adults taking high doses of amphetamine-based medications for ADHD, such as Adderall, face a five-fold increased risk of developing psychosis or mania. The risk was highest for those taking 30 mg or more of dextroamphetamine, with 81% of psychosis or mania cases potentially avoidable by lowering the dose.
