MIT researchers developed an ingestible capsule that can monitor vital signs including heart rate and breathing patterns from within a patient’s GI tract. The scientists also say that the novel device has the potential to also be used to detect signs of respiratory depression during an opioid overdose. Giovanni Traverso, an associate professor of mechanical engineering at MIT who has been working on developing a range of ingestible sensors, told Engadget that the device will be especially useful for sleep studies.

Conventionally, sleep studies require patients to be hooked up to a number of sensors and devices. In labs and in at-home studies, sensors can be attached to a patient’s scalp, temples, chest and lungs with wires. A patient may also wear a nasal cannula, chest belt and pulse oximeter which can connect to a portable monitor. “As you can imagine, trying to sleep with all of this machinery can be challenging,” Traverso told Engadget.

This trial, which used a capsule made by Celero Systems —A start-up led by MIT and Harvard researchers— marks the first time ingestible sensor technology was tested in humans. Aside from the start-up and MIT, the research was spearheaded by experts at West Virginia University and other hospital affiliates.

The capsule contains two small batteries and a wireless antenna that transmits data. The ingestible sensor, which is the size of a vitamin capsule, traveled through the gastrointestinal tract, and collected signals from the device while it was in the stomach. The participants stayed at a sleep lab overnight while the device recorded respiration, heart rate, temperature and gastric motility. The sensor was also able to detect sleep apnea in one of the patients during the trial. The findings suggest that the ingestible was able to measure health metrics on par with medical-grade diagnostic equipment at the sleep center. Traditionally, patients that need to get diagnosed with specific sleep disorders are required to stay overnight at a sleep lab, where they get hooked onto an array of sensors and devices. Ingestible sensor technology eliminates the need for that.

Importantly, MIT says there were no adverse effects reported due to capsule ingestion. The capsule typically passes through a patient within a day or so, though that short internal shelf life may also limit how effective it could be as a monitoring device. Traverso told Engadget that he aims to have Celetro, which he co-founded, eventually contain a mechanism that will allow the capsule to sit in a patient’s stomach for a week.

Dr. Ali Rezai, the executive chair of the West Virginia University Rockefeller Neuroscience Institute, said that there is a huge potential for creating a new pathway through this device that will help providers identify when a patient is overdosing according to their vitals. In the future, researchers even anticipate that devices could incorporate drugs internally: overdose reversal agents, such as nalmefene, could be slowly administered if a sensor records that a person’s breathing rate slowed or stopped. More data from the studies will be made available in the coming months.

The I-10 Freeway Fire May Have Been Caused by Exploding Hand Sanitizer

https://www.wired.com/story/i-10-freeway-fire-cause-hand-sanitizer/


Shortly after a massive fire under the Interstate 10 freeway in downtown Los Angeles last weekend closed a 1-mile stretch normally traversed by 300,000 vehicles daily, California’s fire marshal announced that it was being investigated as possible arson.

Some locals have been eager to blame the homeless encampments that are common under California’s freeway overpasses, despite LA mayor Karen Bass saying this week that “there is no reason to assume that the reason this fire happened was because there were unhoused individuals nearby.”

Now there’s evidence that excess pandemic hand sanitizer may have contributed to the blaze. The Los Angeles Times reported this week that unnamed sources said that hand sanitizer, which is highly flammable, stored under the freeway may have worsened the I-10 destruction. The owner of a company subleasing storage space under the overpass tells WIRED he was storing half a pallet of hand sanitizer that had been left unsold after pandemic restrictions lifted.

If hand sanitizer is confirmed to have contributed to the I-10 disaster, it could be added to a growing list of tragic fires fueled by surplus sanitizer from the pandemic.

California authorities have so far released little information about the cause of the fire, citing the ongoing investigation. They have said that the space under the freeway was leased out by California’s transportation department to an entity that Governor Gavin Newsom called a “bad actor,” and who allowed many items to be stored under the overpass.

An attorney for Calabasas-based Apex Development sent out a news release Wednesday night objecting to being called a “bad actor.” In September, the state had filed a lawsuit alleging that Apex had stopped paying rent for the past year while subleasing the property out to at least five other businesses. Google Street View imagery of the stretch that burned shows plenty of boxes and wooden pallets under the freeway, leaving little room for any large encampments.

Apex Development’s CEO Anthony Nowaid has not yet returned messages from WIRED. The news release that Apex Development’s attorney sent out Wednesday night blames the fire on “public safety issues caused by the unhoused.”

Rudy Serafin, who owns one of the businesses that had been subleasing the space, tells WIRED that he did not notice any homeless people near the site the day before the fire, other than some cars parked along one street that he assumed belonged to people living in them. Serafin said he was using his lot to store the hand sanitizer he had been unable to sell after demand for it during the pandemic dropped. He estimates that he had between 100 and 125 bottles under the overpass.

A Spy Agency Leaked People’s Data Online—Then the Data Was Stolen

https://www.wired.com/story/ntmc-bangladesh-database-leak/


The list of data is long. Names, professions, blood groups, parents’ names, phone numbers, the length of calls, vehicle registrations, passport details, fingerprint photos. But this isn’t a typical database leak, the kind that happens all the time—these categories of information are all linked to a database held by an intelligence agency.

For months, the National Telecommunication Monitoring Center (NTMC), an intelligence body in Bangladesh that’s involved in collecting people’s cell phone and internet activity, has published people’s personal information through an unsecured database linked to its systems. And this past week, anonymous hackers attacked the exposed database, wiping details from the system and claiming to have stolen the trove of information.

WIRED has verified a sample of real-world names, phone numbers, email addresses, locations, and exam results included in the data. However, the exact nature and purpose of the amassed information is unclear, with some entries appearing to be test information, incorrect, or partial records. The NTMC and other officials in Bangladesh have not responded to requests for comment.

The disclosure, which appears to have been unintentional, provides a tiny glimpse into the highly secretive world of signals intelligence and how communications may be intercepted. “I wouldn’t be expecting this to happen for any intelligence service, even if it’s not really something that sensitive,” says Viktor Markopoulos, a security researcher for CloudDefense.AI who discovered the unsecured database. “Even if many data are test data, they still reveal the structure that they’re using, or what exactly it is that they are intercepting or plan to intercept.”

After Markopoulos discovered the exposed database, he linked it back to the NTMC and login pages for a Bangladeshi national intelligence platform. Markopoulos believes the database was likely exposed due to a misconfiguration. Within the database, there are more than 120 indexes of data, with different logs stored in each. The indexes include names such as “sat-phone,” “sms,” “birth registration,” “pids_prisoners_list_search,” “driving_licence_temp,” and “Twitter.” Some of those files contain a handful of entries each, while others contain tens of thousands.

The vast majority of the data exposed in the NTMC database is metadata—the extremely powerful “who, what, how, and when” of everyone’s communications. Phone call audio isn’t exposed, but metadata shows which numbers may have called others and how long each call lasted. This kind of metadata can be used broadly to show patterns in people’s behavior and whom they interact with.

YouTube’s first AI-generated music tools can clone artist voices and turn hums into melodies

https://www.engadget.com/youtubes-first-ai-generated-music-tools-can-clone-artist-voices-and-turn-hums-into-melodies-132025817.html

YouTube on Thursday unveiled some new experimental AI services, including a feature called Dream Track in YouTube Shorts. It creates up to 30-second soundtracks using AI-generation versions of artists’ voices. Though musicians have mostly pushed back on AI (and their voices being used for training models without permission or compensation), YouTube got nine big names from the music industry to participate, including John Legend, Troye Sivan, CharliXCX and T-Pain. The company hoped to announce the feature at its Made on YouTube event in September, but it’s been tied up in negotiations with recording companies over rights and payments.

Users can access Dream Track by typing an idea into the creation prompt and choosing from one of the participating artists. It uses Google DeepMind’s Lyria — a new, powerful music generation model designed specifically for creating high-quality vocals and instrumentals while giving the user more control over the final product. Any content Lyria produces will also have a SynthID watermark, denoting it as such. 

Charlie Puth and T-Pain created sample Dream Tracks, which YouTube has shared as inspiration. However, many of the artists involved expressed their apprehension about AI but hoped that collaborative work could create positive, non-exploitative opportunities. "When I was first approached by YouTube I was cautious and still am, AI is going to transform the world and the music industry in ways we do not yet fully understand," singer CharliXCX said. "This experiment will offer a small insight into the creative opportunities that could be possible and I’m interested to see what comes out of it." 

Music AI Tools are also coming to YouTube, in collaboration with its Music AI Incubator. These tools can create guitar riffs from a hummed melody or turn a pop track into a reggaeton anthem. Producer and songwriter, Louis Bell, created a sample video to showcase it. 

YouTube is walking a fine line as it navigates the careful balance of introducing AI tools and protecting against misuse. The video platform recently announced new policies for labeling videos made using AI and letting public figures, such as musicians, report deepfakes. 

Dream Track is currently only available to a select group of creators and artists, whereas participants of the Music AI Incubator should be able to test the tools out later this year.

Airbus Launches Device to Keep Dead Satellites from Tumbling in Space

https://gizmodo.com/airbus-launches-device-to-keep-dead-satellites-from-tum-1851021678

Earth’s orbit can be a chaotic place, with defunct spacecraft darting aimlessly across the dark skies. In order to tackle the growing issue of space debris, Airbus created a new device designed to keep satellites from tumbling around after they’re no longer of use.

Astronomers Could Soon Get Warnings When SpaceX Satellites Threaten Their View

The device, aptly named Detumbler, launched on Saturday on board a Falcon 9 rocket from California’s Vandenberg Space Force Base. It was one 90 payloads to liftoff as part of SpaceX’s Transporter-9 mission.

Detumbler is a magnetic damping device that’s meant to be attached to a satellite that’s nearing the end of its life, according to Airbus. Weighing around 100 grams, Detumbler has a central rotor wheel and magnets that interact with the Earth’s magnetic field, which prevents unwanted motion when defunct satellites start to tumble. The device is designed to behave like a compass when the satellite is flying normally in its orbit, aligning with Earth’s magnetic field. If it begins to tumble, however, the movement of the rotor will trigger eddy currents (loops of electrical current within conductors induced by a changing magnetic field) and cause friction to slow down the motion.

The device was developed by Airbus in 2021 with support from the French Space Agency CNES under its Tech4SpaceCare initiative. The main purpose is to address the growing risk of space debris. Dead satellites tend to tumble in unpredictable ways due to orbital flight dynamics, posing a risk of crashing into another spacecraft or making uncontrolled reentries through Earth’s atmosphere.

The Detumbler, however, would make it easier to capture defunct satellites by future missions aimed at cleaning up space debris by keeping them on a more predictable path in Earth orbit. Airbus’ new device will be tested on the Exo-0 nanosatellite from EnduroSat in early 2024 with a series of detumbling demonstrations.

There are more than 27,000 pieces of orbital debris that are currently being tracked by the Department of Defense’s global Space Surveillance Network, with lots of smaller pieces also floating around undetected. That number is only expected to increase as the global space industry continues to grow, increasing the chances of collision right above our heads. Things have gotten so bad already that the target of a recently launched space debris clean-up mission was struck by space debris in August, highlighting just how important mitigation methods are needed today.

Microplastics Could Be Affecting the Weather, Too

https://gizmodo.com/microplastics-could-be-affecting-the-weather-too-1851021523


New research this week is the latest to show that microplastics have polluted just about everywhere on Earth. Scientists discovered plastic particles in cloud samples collected from atop a mountain in Eastern China. The team also found evidence from lab experiments that these microplastics could potentially affect cloud formation and the weather, though more data will be needed to understand exactly how.

Coastal Animals Are Thriving on Plastic Pollution Out in the Pacific Ocean | Extreme Earth

The study was led by scientists from Shandong University. Among other things, they were inspired by a recent study published in September—one where scientists found microplastics in samples of mist collected at the peaks of Mount Fuji and Mount Oyama, both in Japan. The team decided to look for and analyze microplastics in the clouds surrounding the top of Mount Tai, a well-visited and culturally important mountain that’s close to densely populated areas of Eastern China. They studied 28 liquid samples collected during summer 2021.

The team found microplastics in all but four of the samples. These samples contained common plastics such as polyethylene terephthalate, polypropylene, and polyethylene. Samples collected from low-altitude and denser clouds also tended to have greater amounts of microplastics. The concentration of plastics found in the samples overall was substantially lower than those collected from the atmosphere of urban areas, the researchers noted, but much higher than those found in nearby rainfall, remote polar regions, and the cloud water previously collected from Mount Fuji and Mount Oyama in Japan.

“This finding provides significant evidence of the presence of abundant [microplastics] in clouds,” the researchers wrote in their paper, published Wednesday in Environmental Science & Technology Letters.

The team additionally conducted a deeper analysis of the microplastics they found, as well as modeling and lab experiments. The older plastic particles tended to be rougher and smaller, for instance, and contained more lead, mercury and oxygen on average than fresher plastics. In the lab, they found that exposing plastics to cloud-like conditions—namely, ultraviolet radiation and filtered water—could cause these same sorts of changes. In other words, they found evidence that clouds can change the makeup of microplastics once they get there, possibly in ways that could then affect cloud formation and subsequently the weather.

There’s still a lot that we don’t know about the specific effects of microplastics, both on the environment and our health, but what we have learned so far hasn’t been comforting. Studies have identified over a hundred chemicals in plastic that could potentially harm us or other animals, including those that disrupt the regulation of important hormones. Chemicals from plastic pollution can also leak into soil and freshwater causing long-term negative consequences for the surrounding ecosystem.

The study authors say that more research will be needed to figure out how microplastics interact with clouds and the potential impacts of these interactions on cloud formation and the presence of toxic metals in the atmosphere. Many scientists, environmental, and public health organizations have already begun to call for widespread reductions in plastic pollution based on the possible dangers we know about.

Roland’s new software instrument Galaxias offers access to 20,000 sounds

https://www.engadget.com/rolands-new-software-instrument-galaxias-offers-access-to-20000-sounds-010004849.html?src=rss

Roland just unveiled its latest software plugin instrument. Galaxias, not to be confused with the Galaga-esque arcade game Galaxia, offers access to 20,000 sounds, leading Roland to call it “one big super instrument.” It runs as a standalone application on both macOS and Windows, in addition to operating as a VST3 or AU plugin.

This looks a lot like Arturia’s amazing Analog Lab software, as Galaxias provides access to sounds across Roland’s entire history. There are presets sourced from nearly every Roland instrument you can think of, from the iconic Jupiter 8 synthesizer to the, uh, even more iconic TR 808 drum machine. These sounds aren’t just from retro darlings, as there are plenty of options culled from recent releases like System 8 and Zenology, among others.

As a matter of fact, the company says Galaxias provides access to any instrument available via Roland Cloud. You can also layer up to four instruments together, along with two effects per layer, to create custom soundscapes that Roland calls Scenes. Additionally, there are some beefed up adjustment parameters here, with macro controls that let you change up 128 parameters via internal LFOs or an external MIDI controller.

Just like Analog Lab, everything’s designed around a proprietary interface that allows for custom organization options, so you won’t lose your favorite preset in a mad dash to find the beefiest bassline. Roland also says that more sounds and capabilities will be added regularly.

Galaxias is available now and is included with a Roland Cloud Ultimate membership, which costs $200 per year or $20 each month. There’s a 30-day free trial for those curious about what all the fuss is about.
