This past May 14, 2073, marked the 50th anniversary of Skylab, the first American space station. While Skylab may be remembered for its fiery ending, it is important to acknowledge its beginning and the significant contributions it made to space exploration.

“Skylab: Pioneering Contributions to Space Exploration”

Skylab was launched on May 14, 1973, as part of NASA’s effort to establish a long-duration human presence in space. The space station was originally a repurposed Saturn V rocket, and it was the largest spacecraft ever launched at the time. Three astronaut crews occupied Skylab for a total of 171 days, conducting experiments and research in various fields, including solar physics, Earth observations, and medical studies.

One of the most significant contributions of Skylab was its role in advancing our understanding of life in space. The astronauts lived and worked in microgravity for extended periods, which allowed scientists to study the effects of weightlessness on the human body. They also conducted experiments on plant growth in space, paving the way for future space agriculture.

Skylab was not without its challenges, though. The space station experienced a number of technical difficulties during its lifetime, including a solar panel malfunction that threatened to cut off power to the entire station. However, the ingenuity and resourcefulness of the astronauts and ground crew allowed them to overcome these obstacles and continue their research.

While Skylab’s mission ended prematurely with its re-entry into Earth’s atmosphere on July 11, 1979, it left a lasting impact on space exploration. The lessons learned from Skylab laid the foundation for the International Space Station, which has been continuously occupied by humans since 2000.

The 50th anniversary of Skylab is a reminder of the pioneering spirit of the early days of space exploration and the significant contributions that were made to advance our understanding of life in space. Skylab may have had a fiery ending, but its legacy lives on in the continued exploration of space.

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

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.

Could fungi actually cause a zombie apocalypse?

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.


Is a zombie apocalypse caused by fungi, like the Cordyceps from “The Last of Us,” something that could realistically happen? – Jupiter, age 15, Ithaca, New York


Zombies strike fear into our hearts – and if they’re persistent, eventually they get inside our heads. Animals taken over by zombies no longer control their own bodies or behaviors. Instead, they serve the interests of a master, whether it’s a virus, fungus or some other harmful agent.

The term “zombi” comes from Vodou, a religion that evolved in the Caribbean nation of Haiti. But the idea of armies of undead, brain-eating human zombies comes from movies, such as “Night of the Living Dead,” television shows like “The Walking Dead” and video games like Resident Evil.

Those all are fictional. Nature is where we can find real examples of zombification – one organism controlling another organism’s behavior.

I study fungi, a huge biological kingdom that includes molds, mildews, yeasts, mushrooms and zombifying fungi. Don’t worry – these “brain-eating organisms” tend to target insects.

The fungus Ophiocordyceps unilateralis infects and kills ants. Over time, they can diminish the local ant population.

Insect body snatchers

One of the most famous examples is the zombie ant fungus, Ophiocordyceps unilateralis, which is part of a larger group known as Cordyceps fungi. This fungus inspired the video game and HBO series “The Last of Us,” in which a widespread fungal infection turns people into zombie-like creatures and causes society to collapse.

In the real world, ants usually come into contact with this fungus when spores – pollen-size reproductive particles that the fungus makes – fall onto the ant from a tree or plant overhead. The spores penetrate the ant’s body without killing it.

Once inside, the fungus spreads in the form of a yeast. The ant stops communicating with nestmates and staggers around aimlessly. Eventually it becomes hyperactive.

Finally, the fungus causes the ant to climb up a plant and lock onto a leaf or a stem with its jaws – a behavior called summiting. The fungus changes into a new phase and consumes the ant’s organs, including its brain. A stalk erupts from the dead insect’s head and produces spores, which fall onto healthy ants below, starting the cycle again.

Scientists have described countless species of Ophiocordyceps. Each one is tiny, with a very specialized lifestyle. Some live only in specific areas: for example, Ophiocordyceps salganeicola, a parasite of social cockroaches, is found only in Japan’s Ryukyu Islands. I expect that there are many more species around the world awaiting discovery.

The zombie cicada fungus, Massospora cicadina, has also received a lot of attention in recent years. It infects and controls periodical cicadas, which are cicadas that live underground and emerge briefly to mate on 13- or 17-year cycles.

The fungus keeps the cicadas energized and flying around, even as it consumes and replaces their rear ends and abdomens. This prolonged “active host” behavior is rare in fungi that invade insects. Massospora has family members that target flies, moths, millipedes and soldier beetles, but they cause their hosts to summit and die, like ants affected by Ophiocordyceps.

The real fungal threats

These diverse morbid partnerships – relationships that lead to death – were formed and refined over millions of years of evolutionary time. A fungus that specializes in infecting and controlling ants or cicadas would have to evolve vastly new tools over millions more years to be able to infect even another insect, even one that’s closely related, let alone a human.

In my research, I’ve collected and handled hundreds of living and dead zombie cicadas, as well as countless fungus-infected insects, spiders and millipedes. I’ve dissected hundreds of specimens and uncovered fascinating aspects of their biology. Despite this prolonged exposure, I still control my own behavior.

Some fungi do threaten human health. Examples include Aspergillus fumigatus and Cryptococcus neoformans, both of which can invade people’s lungs and cause serious pneumonia-like symptoms. Cryptococcus neoformans can spread outside the lungs into the central nervous system and cause symptoms such as neck stiffness, vomiting and sensitivity to light.

Invasive fungal diseases are on the rise worldwide. So are common fungal infections, such as athlete’s foot – a rash between your toes – and ringworm, a rash that despite its name is caused by a fungus.

Fungi thrive in perpetually warm and wet environments. You can protect yourself against many of them by showering after you get sweaty or dirty and not sharing sports gear or towels with other people.

Not all fungi are scary, and even the alarming ones won’t turn you into the walking dead. The closest you’re likely to come to a zombifying fungus is through watching scary movies or playing video games.

If you’re lucky, you might find a zombie ant or fly in your own neighborhood. And if you think they’re cool, you could become a scientist like me and spend your life seeking them out.

The Incident

Intelsat 33e suffered a crippling power loss due to an anomaly, rendering it inactive in its geostationary orbit. Efforts made by Intelsat, in collaboration with Boeing, the satellite’s manufacturer, have been futile, making the satellite irrecoverable. As a direct consequence, the U.S. Space Force is now tasked with managing and tracking 20 newly formed debris pieces—an endeavor crucial to preventing further orbital hazards.

The cause of Intelsat 33e’s failure is yet to be confirmed, but speculation suggests a propulsion system malfunction. This incident echoes a similar fate that befell Intelsat-29e in 2019, attributed to either a meteoroid strike or possible wiring issues. Such events highlight the unpredictable nature of space operations and the resultant challenges.

Risks and Implications

Geostationary orbit, where these incidents occurred, is particularly sensitive. With satellites positioned to maintain a fixed point relative to the Earth, any increase in debris could severely limit maneuverability and heighten collision risks. Each new debris field exacerbates the congestion in these critical orbital paths, increasing the threat to operational satellites and, by extension, to the services they provide to millions globally.

Moving Forward

In light of these challenges, the space community is called upon to fortify its commitment to space sustainability. Satellite operators must adopt strategies that prioritize the careful deployment and maintenance of satellites to avoid contributing to the burgeoning space debris problem. This incident underscores the fragility of space infrastructure and the necessity for methodical, responsible practices.

Maintaining space situational awareness is essential. Vigilant tracking and management of debris can mitigate collision risks, ensuring the safety and functionality of existing and future missions. Such measures not only protect the substantial investments in space infrastructure but also guarantee the continuity of vital services reliant on satellite communication.

Collaborative Efforts for a Sustainable Space Environment

Addressing the challenges posed by space debris requires a collective effort. Satellite operators, governments, and international organizations must collaborate to develop and implement solutions that enhance the resilience and sustainability of space operations. By sharing data, adopting standardized practices, and investing in technologies for debris monitoring and removal, stakeholders can work towards a safer, more sustainable orbital environment.

The breakup of Intelsat 33e serves as a stark reminder of the complexities within space exploration and the need for proactive measures. Only through collective vigilance and innovation can we hope to protect the orbital space environment, ensuring that it remains a viable domain for technological advancement and discovery for generations to come.
