The Colorado June air was thick with summer heat. Mosquitoes rose in clouds around us, testing our resolve while we gathered our cameras and sensors. We walked into the wetland, down the unmarked path until the cattails rose shoulder-high. The sounds of frogs and crickets filled the air as we set up our cameras and waited. Then we spotted them: tiny lights lifting from the grasses, blinking in slow rhythms.

Bioluminescent lampyrid beetles, commonly known as fireflies or lightning bugs, are widespread throughout the Eastern United States but far more scarce west of Kansas.

Even though many are stargazers and hikers, most Colorado residents don’t know that fireflies share their state.

We are an associate professor of computer science and a Ph.D. candidate who are working to shed light on Colorado’s hidden fireflies.

In the past few years, we have observed and filmed elusive bioluminescent fireflies all over Colorado, racing each summer against their brief and unpredictable flashing season.

Last year in early June it was too early, we thought, for fireflies in Colorado. For weeks we had been checking weather forecasts, comparing them to previous years, waiting for warmer nights and rising temperatures − the signs that would tell us it’s firefly time.

Then we got a tip. A friend mentioned seeing one or two flashes near their property. The next morning we packed our gear, rearranged our schedules and contacted our volunteer network. The field season began in a literal flash.

As adults, fireflies live and flash for only about two weeks a year − and even then, just for a few hours each night. It’s easy to blink and miss the entire season. The next generation overwinters underground as larvae, emerging as adults the following year, though development may take up to two years in arid climates. Making the most of that narrow window is one of the many reasons we rely on volunteers who help us spot the first flashes and record observations across Colorado.

Western fireflies face unique environmental challenges

Our work joins a growing chorus of scientific observation focused on western fireflies, which pop up across the arid landscape near temporary wetlands, marshes, drainages, desert rivers and other water sources. Because of the dry landscape, these populations tend to be fragmented, isolated to where the water is and nowhere in between.

This strong tie to small, unstable habitat spells vulnerability for the fireflies. If the water runs out, or their habitats are damaged by water or light pollution, the flashing populations could vanish. Pesticides in water are toxic to firefly larvae and their prey, and artificial light inhibits the flash courtship between males and females, preventing successful reproduction. Many populations and species of fireflies are threatened with extinction in the United States due to these factors.

Organizations such as our lab at the University of Colorado and the Xerces Society for Inverteberate Conservation are studying the distribution of and direct threats to western firefly populations. Many of the species are either endangered or not yet described.

The fireflies of the Photuris genus along the Front Range, for example, still do not have a species name and appear to be genetically distinct from other Photuris around the country. Preliminary genetic results suggest at least one new species might be found here. The genetic data also suggests at least five different bioluminescent species of fireflies are present in Colorado.

How flash patterns help fireflies (and us) tell species apart

During their short mating season, fireflies use their flash patterns as mating calls.

Males produce a series of flash-on, flash-off events, each with specific durations and pauses. These Morse code-like signals communicate what type and how fit the fireflies are to potential mates in the darkness.

When females detect a suitable male, they respond with their own unique flash pattern.

Our work piggybacks on this evolutionary adaptation. We first recorded populations from around the U.S. using two video cameras, which allowed us to accurately track individual fireflies in three dimensions and separate their flash patterns.

We used the data on the flash behavior from different species to train a neural network that can classify the firefly’s flash pattern with a high degree of accuracy. Our algorithm learns the unique flash patterns from our data and can identify the species of firefly that is present in a video.

This is a powerful tool for firefly conservation efforts. The camera footage can cover more time and ground than field surveys conducted by humans, and our algorithm can more quickly identify species that might be threatened.

Fostering community engagement with citizen science

Based on our success with community science data collection across other states, including Tennessee, South Carolina and Massachusetts, we wanted to apply the same principles to Colorado’s firefly populations. This is a big undertaking: There are dozens of fragmented sites where fireflies are active across Colorado, and more are reported by volunteers every season. Our team of two cannot visit and survey every site during the short firefly season.

In 2023 we put out our first call for volunteers in Colorado. Since that time, 18 community members in Boulder, Fort Collins, Divide and Loveland joined the filming effort. We provide cameras for the volunteers, who bring them to their nearby wetlands and set them up in the fading light.

Last summer we partnered with local land management agencies in Boulder, Fort Collins and Loveland to host informative community events, where we spoke about firefly biology and conservation to audiences of all ages. On many of those nights, as the flashes began, we heard the excitement build: quiet gasps, hushed enthusiasm and a whisper such as, “Look at that beautiful streak of light!”

Fireflies have an important story to tell, and here in Colorado that story is just beginning. Their brief flashes each summer help us learn about communication, ecology and how these delicate insects respond to an ever-changing world.

Artificial Intelligence

As OpenAI attracts billions in new investment, its goal of balancing profit with purpose is getting more challenging to pull off

Published

OpenAI, the artificial intelligence company that developed the popular ChatGPT chatbot and the text-to-art program Dall-E, is at a crossroads. On Oct. 2, 2024, it announced that it had obtained US$6.6 billion in new funding from investors and that the business was worth an estimated $157 billion – making it only the second startup ever to be valued at over $100 billion.

Unlike other big tech companies, OpenAI is a nonprofit with a for-profit subsidiary that is overseen by a nonprofit board of directors. Since its founding in 2015, OpenAI’s official mission has been “to build artificial general intelligence (AGI) that is safe and benefits all of humanity.”

By late September 2024, The Associated Press, Reuters, The Wall Street Journal and many other media outlets were reporting that OpenAI plans to discard its nonprofit status and become a for-profit tech company managed by investors. These stories have all cited anonymous sources. The New York Times, referencing documents from the recent funding round, reported that unless this change happens within two years, the $6.6 billion in equity would become debt owed to the investors who provided that funding.

The Conversation U.S. asked Alnoor Ebrahim, a Tufts University management scholar, to explain why OpenAI’s leaders’ reported plans to change its structure would be significant and potentially problematic.

How have its top executives and board members responded?

There has been a lot of leadership turmoil at OpenAI. The disagreements boiled over in November 2023, when its board briefly ousted Sam Altman, its CEO. He got his job back in less than a week, and then three board members resigned. The departing directors were advocates for building stronger guardrails and encouraging regulation to protect humanity from potential harms posed by AI.

Over a dozen senior staff members have quit since then, including several other co-founders and executives responsible for overseeing OpenAI’s safety policies and practices. At least two of them have joined Anthropic, a rival founded by a former OpenAI executive responsible for AI safety. Some of the departing executives say that Altman has pushed the company to launch products prematurely.

Safety “has taken a backseat to shiny products,” said OpenAI’s former safety team leader Jan Leike, who quit in May 2024.

Why would OpenAI’s structure change?

OpenAI’s deep-pocketed investors cannot own shares in the organization under its existing nonprofit governance structure, nor can they get a seat on its board of directors. That’s because OpenAI is incorporated as a nonprofit whose purpose is to benefit society rather than private interests. Until now, all rounds of investments, including a reported total of $13 billion from Microsoft, have been channeled through a for-profit subsidiary that belongs to the nonprofit.

The current structure allows OpenAI to accept money from private investors in exchange for a future portion of its profits. But those investors do not get a voting seat on the board, and their profits are “capped.” According to information previously made public, OpenAI’s original investors can’t earn more than 100 times the money they provided. The goal of this hybrid governance model is to balance profits with OpenAI’s safety-focused mission.

Becoming a for-profit enterprise would make it possible for its investors to acquire ownership stakes in OpenAI and no longer have to face a cap on their potential profits. Down the road, OpenAI could also go public and raise capital on the stock market.

Altman reportedly seeks to personally acquire a 7% equity stake in OpenAI, according to a Bloomberg article that cited unnamed sources.

That arrangement is not allowed for nonprofit executives, according to BoardSource, an association of nonprofit board members and executives. Instead, the association explains, nonprofits “must reinvest surpluses back into the organization and its tax-exempt purpose.”

What kind of company might OpenAI become?

The Washington Post and other media outlets have reported, also citing unnamed sources, that OpenAI might become a “public benefit corporation” – a business that aims to benefit society and earn profits.

Examples of businesses with this status, known as B Corps., include outdoor clothing and gear company Patagonia and eyewear maker Warby Parker.

It’s more typical that a for-profit businessnot a nonprofit – becomes a benefit corporation, according to the B Lab, a network that sets standards and offers certification for B Corps. It is unusual for a nonprofit to do this because nonprofit governance already requires those groups to benefit society.

Boards of companies with this legal status are free to consider the interests of society, the environment and people who aren’t its shareholders, but that is not required. The board may still choose to make profits a top priority and can drop its benefit status to satisfy its investors. That is what online craft marketplace Etsy did in 2017, two years after becoming a publicly traded company.

In my view, any attempt to convert a nonprofit into a public benefit corporation is a clear move away from focusing on the nonprofit’s mission. And there will be a risk that becoming a benefit corporation would just be a ploy to mask a shift toward focusing on revenue growth and investors’ profits.

Many legal scholars and other experts are predicting that OpenAI will not do away with its hybrid ownership model entirely because of legal restrictions on the placement of nonprofit assets in private hands.

But I think OpenAI has a possible workaround: It could try to dilute the nonprofit’s control by making it a minority shareholder in a new for-profit structure. This would effectively eliminate the nonprofit board’s power to hold the company accountable. Such a move could lead to an investigation by the office of the relevant state attorney general and potentially by the Internal Revenue Service.

What could happen if OpenAI turns into a for-profit company?

The stakes for society are high.

AI’s potential harms are wide-ranging, and some are already apparent, such as deceptive political campaigns and bias in health care.

If OpenAI, an industry leader, begins to focus more on earning profits than ensuring AI’s safety, I believe that these dangers could get worse. Geoffrey Hinton, who won the 2024 Nobel Prize in physics for his artificial intelligence research, has cautioned that AI may exacerbate inequality by replacing “lots of mundane jobs.” He believes that there’s a 50% probability “that we’ll have to confront the problem of AI trying to take over” from humanity.

And even if OpenAI did retain board members for whom safety is a top concern, the only common denominator for the members of its new corporate board would be their obligation to protect the interests of the company’s shareholders, who would expect to earn a profit. While such expectations are common on a for-profit board, they constitute a conflict of interest on a nonprofit board where mission must come first and board members cannot benefit financially from the organization’s work.

The arrangement would, no doubt, please OpenAI’s investors. But would it be good for society? The purpose of nonprofit control over a for-profit subsidiary is to ensure that profit does not interfere with the nonprofit’s mission. Without guardrails to ensure that the board seeks to limit harm to humanity from AI, there would be little reason for it to prevent the company from maximizing profit, even if its chatbots and other AI products endanger society.

Regardless of what OpenAI does, most artificial intelligence companies are already for-profit businesses. So, in my view, the only way to manage the potential harms is through better industry standards and regulations that are starting to take shape.

California’s governor vetoed such a bill in September 2024 on the grounds it would slow innovation – but I believe slowing it down is exactly what is needed, given the dangers AI already poses to society.

Why do people get headaches and migraines? A child neurologist explains the science of head pain and how to treat it

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to CuriousKidsUS@theconversation.com.


Why do people get headaches? – Evie V., age 10, Corpus Christi, Texas


Whether sharp and stabbing or dull and throbbing, a headache can ruin your day. But your brain doesn’t actually feel pain. So what is going on when it feels like your head is in a vise or about to explode?

I am a child neurologist – that is, a doctor who specializes in diseases of the brain in kids. Most of my patients are kids and adolescents who are struggling with headaches.

Head pain is complicated, and there is still a lot to learn about what causes it and how it can be treated. But researchers know there are a few key players that take part in generating pain.

What are headaches?

Nerves communicate information like pain through electrical signals between the body and the brain.

While the brain itself doesn’t have any nerve sensors to feel pain, blood vessels in the head and structures that protect and surround the brain do sense pain. When these tissues detect injury or damage, they release chemicals that trigger transmission of electrical signals through nerves to tell the brain the head is hurting.

The brain will also use nerves to signal the body to respond to pain with symptoms like feeling tired, teary eyes, runny nose, upset stomach and discomfort in bright or loud environments. It’s not clear why humans evolved to feel these symptoms, but some scientists theorize that this can lead to healthier lifestyle choices to decrease the chance of future headache attacks.

Weather changes are one of the most commonly reported migraine triggers. Danielle Wilhour, a neurologist and headache specialist at University of Colorado Anschutz Medical Campus, explains why shifts in weather can bring on migraines — and what you can do to ease the pain.

What causes headaches?

Often, headaches are a sign that the body is under some kind of stress. That stress triggers chemical and physical changes to the nerves and blood vessels around your brain, head and neck that can cause headaches.

Many types of stresses can cause headaches, including an infection, allergies, hormone changes during puberty and menstrual cycles, not getting enough sleep, not drinking enough water, skipping meals or drinking too much caffeine or alcohol. Sometimes, headaches happen with emotional stress, like feeling anxious or depressed. Even pressure in your sinuses due to changes in the weather can cause your head to hurt.

One in 11 kids have had a type of severe headache called a migraine. They feel like a pulsing and pounding pain in your head and come with other symptoms, including nausea or being sensitive to lights and sounds. During a migraine, it can be hard to do everyday activities because they can make the pain worse. It is also very common to feel unwell or irritable before the head pain starts and after the pain is gone.

Migraines occur when the nerves and other structures used in signaling and interpreting pain aren’t working properly, leading to pain and discomfort from stimulation that wouldn’t normally provoke this. There are many environmental and genetic factors that contribute to this dysfunction. Some people are born with a higher risk of developing migraines. Most people with migraines have someone in their family who also experiences them.

What can treat and prevent headaches?

Identifying what type of headache you’re experiencing is crucial to making sure it is treated properly. Because migraines can be severe, they’re the type of headache that most often leads to doctor’s visits for both kids and adults.

There are several ways to reduce your chances of having headaches, such as drinking plenty of water and limiting caffeine. Eating, sleeping and exercising regularly are other ways you can help prevent headaches.

While painkillers like ibuprofen are often enough to relieve a headache, prescription medications are sometimes necessary to make head pain more bearable. Some medications can also help control or prevent headache episodes. Physical therapy to exercise the body or behavioral therapy to work on the mind can also help you manage headache pain. There are even electronic devices to treat headaches by stimulating different parts of the nervous system.

It is important to talk with a doctor about headaches, especially if it’s a new problem or you experience a change in how they usually feel. Sometimes, brain imaging or blood tests are needed to rule out another health issue.

Recognizing a headache problem early will help your doctor get started on helping you figure out the best way to treat it.
