The Evolution of Wildfire Monitoring Apps: From Alarm to Essential State of Mind in the Western US

CRisti Thomas called 911 for the second time on a warm October day, but when she couldn’t get through, she began to panic. She watched anxiously as a plume of black smoke grew over a rural community in central California.

Just then, I heard a familiar ping.

Watch Duty, an app that warns users of the risk of wildfires and provides critical information in the event of a fire, was already recording the fires. She relaxed. The cavalry was coming.

“I can’t describe the sigh of relief,” she said, recalling the moments after sirens wailed through her neighborhood and helicopters roared overhead. “We saw it happen, so we had questions, and the oversight mandate answered them all.”

Thomas is one of the millions of Watch Duty evangelists who have helped the app spread rapidly. This organization has only been in existence for three years. Currently boasts up to 7.2 million active users At peak times, it receives up to 512 million page views. For a nonprofit organization run mostly by volunteers, those numbers are impressive even by startup standards. But they are not surprising.

Lookout duties have changed the lives of people in fire-prone areas. When the skies darken and ash fills the air, users no longer have to scramble for information, they can now rely on the app to get fast, accurate information for free.

Provides access to critical information about where the danger is, including fire perimeters, evacuation areas, and evacuation location maps. Users can find wildfire camera feeds, track aircraft locations, and see wind data all in one place. The app can also help identify when there is little need for alarm, when risks have subsided, and which agencies are active on the ground.

“This app isn’t just about alerts, it’s about your state of mind,” said Watch Duty CEO John Mills. The Silicon Valley alumnus founded the organization after moving from San Francisco to a large, fire-prone ranch in Sonoma County. After starting in just four California counties, Watch Duty covered the entire state in its first year and quickly expanded from the American West to Hawaii.

As the community grows to reach people in 14 states by 2024, Mills says new features and improved accuracy have made it more popular and filled an unmet need.

It’s not just residents who have become reliant on apps in recent years. A variety of responders, from firefighters to city officials to journalists, are also logging on to ensure key stakeholders are on the same page.

“People thank me for on-duty duty, but I’m like, ‘You’re welcome, I’m sorry you need it,'” Mills said. But it’s clear that the need is real. In each new area we served, word of mouth drove adoption.

“We didn’t spend any money on marketing,” Mills said. “To let the world know that we just let the genie out of the bottle and things are not going back to the way they were.”

It hasn’t been a good year for people concerned about climate change. The expected peak in carbon emissions has not appeared, meaning global warming continues to accelerate (see ‘Humans have warmed the planet by 1.5°C since 1700’). Meanwhile, Donald Trump’s election as US president for a second term and his pledge to “drill, baby, drill” new oil and gas supplies could lead the country to backtrack on climate action. expensive.

Similar sentiments against fossil fuels come from Azerbaijan’s President Ilham Aliyev, who called the oil-rich country’s natural resources a “gift from God.” Aliyev made the comments at the COP29 climate summit in Azerbaijan’s capital Baku. Ironically, this “gift” will become increasingly unavailable as a warming world dries up the Caspian Sea and strands billions of dollars in fossil fuel infrastructure. (See ‘We face climate disaster as the world dries up’).

Given the failure of politicians on the international stage to grasp the reality of climate change, other leaders need to step up, but surprisingly, mayors are the best suited to do so. Maybe it’s the position.

It will be essential for cities to adapt to cope with the unique impacts of urban heat.

Mayors cannot be expected to influence the Earth’s climate, but they oversee the well-being of more than 50 percent of the world’s population who live in urban centers. This number is expected to increase to 70 percent by 2050. Current projections are for spot temperatures to increase by 2.5 degrees Celsius. Adapting cities to deal with the unique effects of urban heat will be essential, from promoting green spaces to investing in buildings that can be cooled without air conditioning (‘Extreme heat makes cities uninhabitable’). (See “How can I survive?”)

The good news is that many mayors already recognize their responsibilities. London Mayor Sadiq Khan aims for the city to be net zero by 2030. Anne Hidalgo, the mayor of Paris, France, planted trees in certain areas and banned cars from passing. Los Angeles Mayor Karen Bass also pledged environmentally friendly changes in preparation for the 2028 Olympics. Organizations like C40 and Climate Mayors are helping to unite local politicians around the world into action. This won’t solve climate change, but it will make life in a warming world more bearable for many people.

Study finds earthquake-triggered piezoelectric effect is essential in the creation of sizable gold nuggets

Posted on by

Gold nuggets reside primarily in quartz veins, and the current paradigm holds that gold precipitates from hydrothermal and carbon dioxide-rich fluids due to changes in temperature, pressure, and/or fluid chemistry. However, the widespread occurrence of large gold nuggets is inconsistent with the dilute nature of these fluids and the chemical inertness of quartz. Quartz is the only abundant piezoelectric mineral on Earth, and the cyclical nature of the seismic activity that drives the formation of gold deposits means that quartz crystals within veins are stressed thousands of times. New research by scientists from Monash University, CSIRO Mineral Resources and the Australian Neutron Scattering Centre suggests that stress on quartz crystals may generate enough voltage to not only electrochemically precipitate gold from solution, but also accumulate gold nanoparticles.

Energy dispersive spectroscopy map of the sample studied by Voysey othersImage courtesy of Chris Voisey.

“Prized for their rarity and beauty, gold nuggets have been at the heart of gold rushes for centuries,” says Monash University geologist Chris Voisey.

“The standard explanation is that gold precipitates from hot, water-rich fluids that flow through cracks in the Earth's crust.”

“As these fluids cool and undergo chemical changes, the gold separates and becomes trapped in the quartz veins.”

“Although this theory is widely accepted, it does not fully explain the formation of large gold nuggets, especially considering the extremely low concentrations of gold in these liquids.”

Dr. Voysey and his colleagues tested a new concept called piezoelectricity.

Quartz, the mineral that typically contains these gold deposits, has a unique property called piezoelectricity, which means it generates an electric charge when subjected to pressure.

This phenomenon is already well known in everyday items such as quartz watches and barbecue lighters, where small mechanical forces generate large voltages.

What if earthquake stresses caused something similar to happen within the Earth?

To test this hypothesis, the researchers conducted experiments designed to replicate conditions that quartz might experience during an earthquake.

They submerged the crystals in a gold-rich liquid and used a motor to apply pressure to it, replicating the shaking of an earthquake.

After the experiment, the quartz samples were examined under a microscope to see if any gold had been deposited.

“The results were surprising,” said Professor Andy Tomkins, from Monash University.

“The stressed quartz not only electrochemically deposited gold on its surface, but also formed and accumulated gold nanoparticles.”

“Surprisingly, the gold tended to deposit on top of existing gold grains rather than forming new gold grains.”

“This is because quartz is an electrical insulator, while gold is a conductor.”

“Once the gold is deposited, it becomes a focus for further growth, effectively attaching even more gold to the gold particle.”

“Our findings provide a plausible explanation for why large gold nuggets form in quartz veins,” Dr Voysey said.

When the quartz is repeatedly compressed by an earthquake, a piezoelectric voltage is generated, causing dissolved gold to be reduced and precipitated from the surrounding liquid.

Over time, this process can accumulate large amounts of gold, eventually producing giant gold nuggets that fascinate treasure hunters and geologists.

“Essentially, the quartz acts like a natural battery, with the gold as its electrodes, slowly accumulating gold with each earthquake,” Dr Voysey said.

“This process may explain why large gold nuggets are frequently associated with quartz veins that form in earthquake-related deposits.”

“This new understanding of the formation of gold nuggets not only solves a long-standing geological mystery, but also highlights the interrelationships between Earth's physical and chemical processes.”

Transform your diet with this essential food pyramid

Posted on by

The food pyramid is a visual representation of a balanced diet, showing the types and proportions of foods that contribute to overall health.

Imagine a pyramid divided into sections, with each section representing a different food group. Specific designs vary, but a typical food pyramid usually includes the following categories from base to apex:

Base (grain)

At the bottom, widest part, are grains like bread, rice, and pasta. These provide complex carbohydrates, which are your primary source of energy. Whole grains are also a good source of added fiber.

Second layer (fruits and vegetables)

Next, fruits and vegetables are rich in vitamins, minerals, fiber, and antioxidants. To get a variety of nutrients, try to eat at least five servings of colorful vegetables each day.

3rd layer (protein)

This section includes proteins like meat, poultry, fish, eggs, beans, nuts, etc. Protein is essential for muscle maintenance, immune function, and growth, and helps you feel fuller for longer.

Top layer (dairy or alternative)

This section discusses fortified alternatives, such as dairy or soy milk, which provide calcium and other essential nutrients needed for bone health.

Outside the pyramid (sweets and fats)

Here are your fats and sweets: While fats are necessary for many bodily functions, choose healthy fats, such as those found in olive oil and avocado. Limit your intake of added sugars and sweets.

The food pyramid acts as a guide to creating a balanced diet by incorporating a variety of foods from different groups while avoiding relying too heavily on one category.

This concept was shaped into a plate in the UK, Eatwell Guide. It tells you how much of each food group you should eat based on the space it takes up on your plate.

According to the Eatwell Guide, eating healthy means making balanced choices from the five food groups over the course of a day or week: one-third fruits and vegetables, one-third grains and starches, and the remaining third a mix of dairy, proteins, and fats, both animal and plant-based.

This article is a response to the question “What is the food pyramid and can it help you eat healthily?” (asked by Diane Weeks from Glasgow).

Scientists harness bottled ‘lightning’ to generate essential ingredients for life

Posted on by
Reply

Nitrogen is an essential element for life and is an integral part of DNA and proteins. Most of the nitrogen on Earth exists in the atmosphere as gaseous nitrogen, denoted as N.2 However, most organisms cannot directly use nitrogen. In modern ecosystems, some microorganisms have specialized enzymes that convert nitrogen into nitrogen.2 It converts gases into a form that other living things can use. Fixed nitrogen These microorganisms Nitrogen fixing bacteria.

But 3 to 4 billion years ago, during a period in Earth's history called the Archean Era, life had not yet evolved and no nitrogen-fixing organisms existed, so scientists studying the origin of life are faced with a classic chicken-and-egg problem: life needed nitrogen to evolve, but before life evolved, there were no microorganisms to convert nitrogen into nitrogen.2 Let's turn gas into something we can use! So where did life get its nitrogen from before there were nitrogen-fixing organisms?

Researchers recently hypothesized that early life on Earth may have obtained fixed nitrogen from lightning. They propose that the high energy of a lightning spark could react with oxygen and N.2 Fixing atmospheric nitrogen2 The gas is converted into other usable forms of nitrogen. Nitrogen oxides.

Geologists have studied the sedimentary rock record to understand nitrogen throughout Earth's history, but they had no way to distinguish lightning-derived nitrogen in rocks from other ancient sources of nitrogen. To explore whether lightning provided fixed nitrogen to early life, researchers led by Dr. Patrick Barth created “lightning” in a jar and tested whether it would react with nitrogen.2 It emitted gases and produced nitrogen oxides that had an identifiable signal.

To simulate lightning, the researchers used electrodes in glass flasks filled with different gas mixtures: To mimic modern-day Earth, Barth and his colleagues used a flask with a composition similar to our current atmosphere, containing 85 percent nitrogen.2 They also used flasks containing an atmosphere similar to that of Archean Earth, which scientists believe was about 83% nitrogen.20% oxygen, 16% carbon dioxide.

The researchers added 50 milliliters (about a quarter cup) of water to the bottom of each flask to allow any nitrogen oxides and other compounds produced during the reaction to dissolve in the water. They discharged each experimental flask to about 50 kilovolts for 15 to 60 minutes — nearly 10 times the voltage of an electric car battery.

The research team developed a device called Quadrupole Gas AnalyzerThey measured the nitrogen compounds in the gases coming out of each flask before and after they were ignited. They found that in the modern experiment, more fixed nitrogen was dissolved in the water than in the gas. But in the Archean experiment, the fixed nitrogen was split almost equally between the water and the gas.

After each reaction, the researchers placed the flask of water into an apparatus that measured the weight of the nitrogen atoms. Gas Source Mass SpectrometerThey explained that nitrogen atoms exist in two main forms with different masses, called isotopes. 14The N isotope is lighter and more abundant in nature, 15The N isotope is heavier and less common. The researchers used mass spectrometer data to calculate the ratios of nitrogen isotopes in the lightning-fixed nitrogen samples. They compared these nitrogen isotope ratios to those in rocks that are 3.1 to 3.8 billion years old to see if there was a match.

The researchers found that the nitrogen isotope ratio of the lightning-produced nitrogen was about 0.1% to 1% lighter than that of the rocks, and suggested that this difference in nitrogen isotopes indicates that most of the nitrogen in the Archean rocks was not produced by lightning.

The researchers also used the lightning flash rate on modern Earth to predict the amount of nitrogen oxides that lightning would produce per year. They estimated that the annual lightning flash rate alone could not have provided enough nitrogen to support ecosystems on early Earth. They explain that there was even less lightning in the Archean than there is today, so even less nitrogen was available to support early life.

The researchers concluded that lightning was not the main source of available nitrogen for early life. Because nitrogen-fixing organisms must have evolved very early in Earth's history, life did not need to rely solely on lightning, they suggested. However, one of the 3.7-billion-year-old rock samples showed nitrogen isotope ratios similar to lightning-fixed nitrogen, leading the researchers to speculate that small amounts of fixed nitrogen from lightning may have supported early life. Furthermore, the researchers suggested that the lightning-fixed nitrogen isotope ratios obtained in this study could be used to investigate how nitrogen is fixed on other planets in the solar system.

Introducing Galaxy Squad: 5 essential tips for selecting a gaming laptop

Posted on by
Reply

When it comes to gaming, the experience is everything. Whether you’re into Fortnite or Baldur’s Gate 3, full immersion is key, and that requires a laptop that can keep up. According to expert Eleanor Alley, who coordinates events at the University of Warwick Esports Center, the laptop you choose will depend on the specific requirements of the game you want to play. From beginners to seasoned pros, there are certain technical aspects that everyone should be aware of…

What should you consider in a gaming laptop?
One crucial factor that can elevate your gaming experience is the speed of your computer. This directly impacts how smoothly the game runs and how realistic the graphics appear. Performance is influenced by three main components: the CPU (Central Processing Unit), which serves as the computer’s “brain”; RAM (Random Access Memory), which stores data required for quick access during operations, similar to short-term memory; and the GPU (graphics processing unit), which generates the images displayed on the screen.

What are the key features of a high-performance gaming laptop?
Nothing is more frustrating than a game freezing at a critical moment, indicating that your computer may not meet the game’s requirements. If the CPU, RAM, or GPU are not powerful enough, loading times and frame rates will suffer. Higher frame rates result in smoother visuals, while faster loading speeds lead to seamless transitions between scenes.

When shopping for a laptop, processing power should be a top consideration. The CPU, the main processor, typically contains multiple cores that handle instructions. While a “quad-core” processor may be adequate for some laptops, those designed for gaming should ideally have 8 or more cores. For top-notch performance, a processor with 16 cores, like the newly launched Intel Core Ultra 7 and Intel Ultra 9 in the Samsung Galaxy Book4 Ultra, is recommended.

Immerse yourself in the action with high-quality audio

Increasing the amount of RAM can also enhance your gaming experience by ensuring smoother gameplay. Insufficient RAM can lead to lag, instability, and frustration. Gaming laptops should ideally have at least 16 GB of RAM, with options for more like the 32 GB available in the Samsung Galaxy Book4 Ultra.

The final piece of the puzzle is the graphics processing unit, which is essential for better visuals and gameplay. A dedicated GPU, separate from the CPU, is crucial for improved performance, especially in demanding games like Red Dead Redemption 2. The Galaxy Book4 Ultra offers two highly acclaimed NVIDIA RTX graphics options.

For Lee, the overall gaming experience hinges on the integration of these elements.

Her recommendation is to compare your system’s specifications with the game’s hardware requirements and test your favorite games on the laptop you’re considering or try out more demanding titles like Baldur’s Gate 3.

What is the ideal screen size for gaming?
Lee suggests a minimum screen size of 15.6 inches, which is met by the 16-inch screen of the Galaxy Book4 Ultra. She advises opting for a screen resolution of at least 1080p and a refresh rate of 120 Hz for an enhanced gaming experience. The Galaxy Book4 series features a 3K screen resolution, providing a superior gameplay experience, especially for players who enjoy first-person games.

Modern laptops utilize AI and high-performance GPUs to create more realistic visuals. Vibrant colors and a visible touchscreen even in bright conditions further enhance the gaming experience.

Besides a great screen, top-notch audio is essential for gamers. Therefore, the inclusion of high-quality speakers and a studio-quality microphone with AI noise cancellation ensures immersive sound and minimal distractions.


How can I ensure my laptop is compatible with gaming hardware?
Portability is a key aspect of laptops. However, this should not limit your ability to use various hardware such as external screens, controllers, charging docks, headsets, and other accessories. Therefore, a laptop with multiple ports is essential. The Galaxy Book4 series laptops are equipped with two Thunderbolt 4 ports, along with USB, HDMI, headphone, and microphone jacks.

What are the most important factors to consider when choosing a gaming laptop?
As long as you have a capable CPU and GPU, sufficient RAM, and a quality screen, you likely have a great gaming laptop. While some may prioritize a 4K display, the graphics processor is more crucial and should be the main focus when balancing costs.

One of the advantages of laptops is their portability, as noted by Lee who values the ability to take it anywhere. In the past, this could mean compromising performance, but modern laptops maintain both portability and power.

There May Be Less Oxygen in Europa’s Ocean, the Essential Fuel for Life, Than Previously Believed

Posted on by
Reply

Jupiter’s moon Europa is covered with an icy shell

NASA/JPL-California Institute of Technology

Jupiter’s moon Europa may not be as ripe for life as we think. Beneath the icy shell is an ocean of water, but as we know, the frigid moon may lack the oxygen needed to support life.

On Europa, oxygen is produced when radiation hits the surface and breaks down the water ice there into its constituent parts hydrogen and oxygen. Models of this process suggest that oxygen production rates can range from 5 kilograms per second to more than 1000 kilograms per second.

Jamie Zareh Researchers at Princeton University made the new estimate using data from the Juno spacecraft, which flew just 353 kilometers above Europa’s surface in 2022. They discovered that oxygen is only produced at a rate of about 12 kilograms per second at the Earth’s surface. This corresponds to the lower bound of previous estimates.

“In a sense, the shell is like Europa’s lungs. It’s continually producing oxygen,” Zaray says. “That said, we can’t say what happens after the oxygen is produced at the surface. How much of the oxygen makes it into the ocean remains a question.”

But if less oxygen is produced in the first place, less oxygen will enter European waters. As a result, researchers may be less likely to discover organisms similar to those living on Earth.

One of the next steps is to figure out how much of that oxygen can penetrate through the alien moon’s icy shell. NASA’s European Clipper mission, scheduled to launch in October, should help solve that problem. It is hoped that this will allow researchers to measure the thickness of the ice and determine whether elements and compounds useful for life can pass through it.

Early Earth conditions could have supported the production of essential life chemicals

Chemical reactions in volcanic pools may have contributed to the birth of life on Earth

Michael S. Nolan/Alamy

One of the most important molecules in living organisms is synthesized from scratch under everyday conditions. The discovery suggests that this chemical formed naturally early in Earth's history and may have played a role in the origin of life.

The substance in question is called pantetheine. It is not a well-known name at the DNA or protein level. However, pantetheine is an important component of a larger molecule called pantetheine. acetyl coenzyme A, A “cofactor” that helps enzymes work.

“Coenzyme A is present in every organism ever sequenced,” he says. Matthew Powner At University College London.

Powner has spent most of his career discovering ways to make biomolecules from simple chemicals in a way that can occur naturally. Over the past decade, he has shown that: aminonitrile can be used to make nucleotide – the building blocks of DNA – and peptide, Short version of protein.

His team has now shown that aminonitrile can be used to make pantetheine in a series of reactions starting with simple chemicals like formaldehyde. This was done in water, often at such dilute concentrations that the reaction mixture appeared like clear water. The team sometimes used heat to speed up their work, but otherwise did not need to intervene once the reaction started.

“We just put everything in one pot. We literally just throw everything in, we don't change anything, we don't do anything, and we have a 60% yield of product,” Powner says.

Acetyl coenzyme A is involved in the synthesis of several biologically important chemicals. Some of the oldest microbial groups use processes involving microorganisms to obtain carbon from the environment.

Importantly, pantetheine is the active portion of the acetyl-coenzyme A molecule. No more than one bit is “essential to its functionality,” Powner says.

This type of cofactor is present in all living organisms.They are described as follows Origin of life and remnants of early evolution.

“Obtaining key organic biological cofactors from scratch,” he says, is impressive, “not to mention one of such centrally important ones.” Zachary Adam from the University of Wisconsin-Madison was not involved in the study.

For Adam, the importance of this research extends beyond pantetheine and acetyl coenzyme A. “They report this particular part of the cofactor, but intermediates have been shown to be important as well,” he says. Other chemicals produced in the process have been shown to aid in the production of other biomolecules. “They're building a network of compounds.”

Many ideas about the origin of life have assumed that a small set of biomolecules formed long before other molecules. For example, the “RNA world” hypothesis states that first life was made solely of RNA, and other chemicals such as proteins and lipids were added after RNA was able to make them. .

Powner is one of several researchers pushing for an alternative scenario in which many important molecules form early and interact from the beginning. “These products can all be products of the same chemical reaction,” he says. Rather than starting with just RNA, or just peptides, “it might be easier to make them all together, so the chemical reactions they perform are integrated from the original state.”

UK AI Safety Association: Setting Standards, Not Tests, is Essential for Artificial Intelligence Safety

Posted on by

The UK should prioritize setting global standards for artificial intelligence testing, instead of attempting to conduct all reviews itself, as suggested by the company responsible for the government’s AI Safety Institute.

Mark Warner, CEO of Faculty AI, emphasized the institute’s commitment to AI safety and its development of technologies for chatbots like ChatGPT. He cautioned that excessive scrutiny of AI models could be limiting.

Last year, Rishi Sunak announced the establishment of the AI Safety Institute (AISI) ahead of a global AI safety summit. This initiative involved collaboration with large tech companies from the EU, UK, US, France, and Japan to prioritize testing of advanced AI models before and after deployment.

The UK’s leading role in AI safety was underscored by the establishment of the Institute, according to Warner, whose London-based company also works with a British lab to test AI model compliance with safety guidelines.

Warner stressed the importance of the institute becoming a global leader in setting testing standards: “I think it’s important to set standards for the wider world rather than trying to do everything ourselves,” he said.

He also expressed optimism about the institute’s potential as an international standard setter, promoting scalability in maintaining AI security and describing it as a long-term vision.

Warner cautioned against the government taking on all testing responsibilities, advocating for the development of standards that other governments and companies can adopt instead.

He acknowledged the challenge of testing every released model and suggested focusing on the most advanced systems.

Intrinsic, supported by Y Combinator, is developing essential infrastructure for trust and safety teams

Karine Mellata and Michael Lin met several years ago while working on Apple’s Fraud Engineering and Algorithmic Risk team. Both Mellata and Lin were involved in addressing online fraud issues such as spam, bots, account security, and developer fraud among Apple’s growing customer base.

Despite their efforts to develop new models to respond to evolving patterns of abuse, Melata and Lin feel they are falling behind and stuck in rebuilding core elements of their trust and safety infrastructure. I did.

“As regulation puts increased scrutiny on teams that centralize somewhat ad hoc trust and safety responses, we are helping modernize this industry and build a safer internet for everyone. We saw this as a real opportunity to do that,” Melata told TechCrunch in an email interview. “We dreamed of a system that could magically adapt as quickly as the abuse itself.”

Co-founded by So Mellata and Lin essentialis a startup that aims to give safety teams the tools they need to prevent product fraud. Intrinsic recently raised $3.1 million in a seed round with participation from Urban Innovation Fund, Y Combinator, 645 Ventures, and Okta.

Intrinsic’s platform is designed to moderate both user-generated and AI-generated content, allowing customers (primarily social media companies and e-commerce marketplaces) to detect and take action on content that violates their policies. We provide the infrastructure to do so. Intrinsic focuses on integrating safety products and automatically orchestrates tasks like banning users and flagging content for review.

“Intrinsic is a fully customizable AI content moderation platform,” said Mellata. “For example, Intrinsic can help publishers creating marketing materials avoid giving financial advice that carries legal liability. We can also help marketplaces discover listings such as:

Mellata notes that there are no off-the-shelf classifiers for such sensitive categories, and even for a well-resourced trust and safety team, adding a new auto-discovered category can take weeks of engineering. They claim it can take several months in some cases. -House.

Asked about rival platforms such as Spectrum Labs, Azure, and Cinder (almost direct competitors), Mellata said Intrinsic is superior in terms of (1) explainability and (2) significantly expanded tools. I said I was thinking about it. He explained that Intrinsic allows customers to “ask questions” about mistakes they made in content moderation decisions and provide an explanation as to why. The platform also hosts manual review and labeling tools that allow customers to fine-tune moderation models based on their own data.

“Most traditional trust and safety solutions were inflexible and not built to evolve with exploits,” Melata said. “Now more than ever, resource-constrained trust and safety teams are looking to vendors to help them reduce moderation costs while maintaining high safety standards.”

Without third-party auditing, it is difficult to determine how accurate a particular vendor’s moderation model is or whether it is susceptible to some type of influence. prejudice It plagues content moderation models elsewhere. But either way, Intrinsic appears to be gaining traction thanks to its “large and established” enterprise customers, who are signing deals in the “six-figure” range on average.

Intrinsic’s near-term plans include increasing the size of its three-person team and expanding its moderation technology to cover not just text and images, but also video and audio.

“The widespread slowdown in the technology industry has increased interest in automation for trust and safety, and this puts Intrinsic in a unique position,” Melata said. “COOs are concerned with reducing costs. Chief compliance officers are concerned with mitigating risk. Embedded helps both. , to catch more fraud.”
