By AJ Dellinger Published February 21, 2025 | Comments (0) | ChatGPT logo appears on a smartphone display Jaap Arriens/NurPhoto (Getty Images) Haishan Yang, a Ph.D. student enrolled at the University of Minnesota, was expelled last year for allegedly using artificial intelligence tools to write his essays. He denies the accusations, claiming that his professors are engaged in a conspiracy against him, according to local Minneapolis NBC affiliate KARE11, and is suing the school over its decision, as it cost him his student visa. At issue for Yang is a preliminary exam he completed remotely while traveling in Morocco during the summer of 2024. The exam required Yang to complete three essays over the course of eight hours using his notes, reports, and booksbut not AI. While Yang contends that he wrote out his answers, his educators disagree. A panel of four professors tasked with reviewing his responses said Yangs essay answers included involved concepts not covered in class, acronyms that are allegedly not commonly used in the field but do regularly appear in ChatGPT-generated answers, and extremely similar formatting and content spotted when comparing Yangs essays to answers provided by ChatGPT when given the same essay questions as prompts. Yang claims the responses were similar because ChatGPT was likely pulling from the same material that he was, but he also believes the professors edited the ChatGPT responses to make them read more like his answers.Both Yang and the professors hold that there is important context outside of just these essay responses that factor into the ruling. On Yangs end, he claims the professors have been out to get hima notion that his advisor backs, for what its worth, telling the review panel, I never have seen this level of animosity directed at a student. According to Yang, he had his financial support cut off by the university for what it claimed was poor performance and disparaging behavior during his time as a research assistant and was told by the graduate director that he should simply quit. He appealed that decision and won, getting his funding back and an apology from the school.As for the professors, they noted that these essays were not the first time Yang was accused of using AI to complete his work. A year earlier, Yang submitted a homework assignment with text in his answer that read re write it (sic), make it more casual, like a foreign student write but no ai. Yang said he used AI to check his English but not to generate answers, and he was ultimately given a warning but did not receive further punishment. Yang lost his case in front of the universitys panel, so now hes going to try it in court. In January, Yang filed state and federal lawsuits against his professor and the University of Minnesota, accusing them of manipulating evidence and lack of due process. According to KARE11, Yang said he did use ChatGPT to write the lawsuit filings.Daily NewsletterYou May Also Like By Thomas Maxwell Published February 20, 2025 By Lucas Ropek Published February 20, 2025 By Margherita Bassi Published February 15, 2025 By Lucas Ropek Published February 14, 2025 By AJ Dellinger Published February 13, 2025 By Lucas Ropek Published February 11, 2025

Image Matti JankalaArchinfo, the Information Centre for Finnish Architecture, has announced the theme, curator, and exhibition team for the Pavilion of Finland at the 19th International Architecture Exhibition of La Biennale di Venezia. The exhibition, titled "The Pavilion Architecture of Stewardship", will focus on the diverse labor involved in constructing and maintaining architecture, from design contributions by architectural workers and engineers to the efforts of construction workers, restoration architects, maintenance staff, and cleaners, all of whom play vital roles in the creation and upkeep of the built environment. Curated by Ella Kaira and Matti Jnkl from the Helsinki-based architecture practice Vokal, it will use Alvar and Elissa Aalto's Pavilion of Finland to explore architecture as a collaborative endeavor.The Pavilion of Finland, designed by Alvar and Elissa Aalto, was built in the Giardini in 1956. Originally intended as a temporary structure, the small wooden pavilion is now a protected cultural heritage site and one of the best-known works of architecture in the Giardini. It is one of only two buildings the modernist architect Alvar Aalto designed in Italy (and the only one completed during his lifetime). "The Pavilion Architecture of Stewardship" is based on the premise that the building carries a mythos that has contributed to its preservation while also obscuring the many contributors to its ongoing existence. The exhibition traces the Pavilion's journey from its construction through decades of continuous maintenance and three major restorations to the present day, positioning those involved in this work as co-creators alongside the original architect.Save this picture!"The Pavilion Architecture of Stewardship" will challenge visitors to rethink their relationship with the built environment and the labor that sustains it by revealing the ongoing process of creation involved in preserving the Pavilion of Finland. The exhibition examines the labor required to ensure the longevity of architecture, questioning who shoulders this responsibility and why it matters. It is founded on the idea that preserving built heritage depends on stewardship, "a practice rooted in care and responsibility". According to the curators, in the context of architecture, stewardship is a shared duty between architects and non-architects, requiring the negotiation of land, resources, and the built environment within an interplay of human and non-human agency. Related Article Healing Through Design: The Story Behind Alvar Aaltos Paimio Sanatorium "The Pavilion of Finland is an architectural icon, but it wouldn't exist without the ongoing labor and care contributed by many workers throughout its life. [...] Our exhibition seeks to ask whether architecture is fixed instruction or an ongoing collaboration, and recognize the importance of a broad range of contributions to the authorship of buildings." - Curator Ella Kaira Save this picture!The exhibition will feature time-based media created by artistic collaborators, including video artist Merle Karp and sound designer Jussi Hertz. According to Katarina Siltavuori, Director of Archinfo and Commissioner of the Pavilion of Finland, it will also pay homage to the contributions of Aalto's wives, Aino and Elissa, to his internationally celebrated work, re-examining the process of authorship. The concept also responds to the Biennale's curatorial theme by questioning common assumptions about creativity and intelligence while celebrating the work of individuals as part of collaborative systems. "The Pavilion was originally designed as a temporary structure but it has become a permanent monument. However, today many buildings that were designed to remain in place are demolished in under 50 years of age. The built environment is treated as a collection of pavilions characterized by ephemerality rather than heritage characterized by permanence. Our exhibition explores the stewardship of our built environment that enables its continued use from one generation to another." - Curator Matti Jnkl Save this picture!The 2025 Venice Biennale marks the fourth time Archinfo has overseen Finland's presentation at the International Architecture Exhibition. In 2018, "Mind-Building" explored the architecture and culture of the Finnish library system, while in 2021, "New Standards" told the post-war story of prefabricated timber Puutalo Houses, one of Finland's most widespread architectural exports. In 2023, the exhibition focused on the traditional Finnish composting toilet in the context of the global climate crisis. This year's proposal aligns with the curatorial work of Carlo Ratti, centered on the theme "Intelligens. Natural. Artificial. Collective." The 19th International Architecture Exhibition La Biennale di Venezia 2025 will run from May 10 to November 23, 2025, offering a broad range of exhibits, discussions, and activities.We invite you to check out ArchDaily's comprehensive coverage of the 2025 Venice Biennale.Image gallerySee allShow lessAbout this authorCite: Antonia Pieiro.

The skulls of Viking-era individuals were examined with modern computed tomography, in the search for infections, inflammations and other diseases. Credit: Carolina BertilssonShareViking life wasnt just tough, it was often chronically painful. For proof, all you need to do is examine their skulls. Thats what researchers at Swedens University of Gothenburg did with the remains of 15 individuals recovered from an archeological site decades ago in Vstergtland Countys Skara municipality.In 2005, an excavation near the towns historic Varnhem Abbey yielded a trove of early Christian Viking remains, including skeletal and dental specimens of over 300 people living between the 10th and12th centuries. While work has since been done to analyze some of their dental records, researchers had yet to conduct detailed examinations of the well-preserved skulls.That recently changed thanks to computed tomography (CT) scanning technology. Using the imaging technique, an interdisciplinary team of forensic dental experts, archeologists, and radiologists, looked at the skulls of nine men and six women who ranged in age from 20 to 60 at their times of death. The results, published February 18 in the journal BDJ Open, indicate Vikings at the time endured a host of maxillofacial diseases, arthritis difficulties, sinuses infections, and other maladies. These would likely have presented recurring health issues, many of which may ultimately have turned fatal.A x-ray of one of the 15 Viking remains. Credit: BDJ Open There was much to look at. We found many signs of disease in these individuals, Carolina Bertilsson, study lead and University of Gothenburg assistant researcher, said in a statement on Friday. Exactly why we dont know. While we cant study the damage in the soft tissue because its no longer there, we can see the traces left in the skeletal structures.According to Bertilsson and her colleagues, subsequent examinations showed many people living in the early Christian community suffered from numerous orofacial pathologies, including sinusitis, otitis, and infection. Many of these issues are not detectable based on purely visual analysis, and are only discoverable thanks to CT scanning technology.Of the 15 Vikings, 11 of them displayed evidence of perlaptical lesions caused by bacterial infections and tooth decay. These often result in abscesses when left untreated, and today require procedures like root canals to treat.In several cases, the bony borders of the lesions were perforated, creating communication with either the maxillary sinus, or the oral cavity, the team writes, adding that in one case a lesion had diffuse borders while another displayed a cyst-like lesion. Basically, dental hygiene wasnt great for the Swedish Vikings. Get the Popular Science newsletter Breakthroughs, discoveries, and DIY tips sent every weekday.

They also theorize that some of these infections likely led to death through the spread of bacteria and sepsis.Researchers were hesitant to draw larger historic conclusions given the small sample size, but hope the project helps highlight the amount of archeological information that can be learned using CT scanning equipment. Apart from anything else, knowing about these chronic health issues allows us to better understand Viking lives.Many of these conditions are highly relatable and give a rare insight into the sufferings of these individuals, write the study authors.

Its an sunny February morning and you turn on the TV to watch the local weather report. The meteorologists forecast says 30 degrees Fahrenheit, which doesnt seem too bad. Its winter after all! But then, you notice that the feels-like temperature is closer to 20 degrees. Suddenly, that extra cup of warm coffee and a fuzzy hat sound really nice.That feels-like temperature can come in the form of wind chill or heat index, so similar scenes can play out during the dog days of summer. The amount of moisture in the airor humiditycan make 80 degrees feel closer to 90.Its basically just how the temperature feels different to our skin, meteorologist Cyrena Arnold tells Popular Science. We have sensors in our skin and our skin is made up of water. So our skin actually behaves differently based upon the evaporation of that water. Get the Popular Science newsletter Breakthroughs, discoveries, and DIY tips sent every weekday. By signing up you agree to our Terms of Service and Privacy Policy.Feels-like: wind chillWhen the air temperature itself is cold and the winds are moving at a higher speed, it can pull more heat away from the body and cause the water on our skin to evaporate faster.In order for moisture to evaporate off of your skin, it takes heat. It has to absorb heat in order for those little water molecules on your skin to go from liquid to a gas, says Arnold. So when theres a wind chill, it doesnt take a lot of energy because of that wind and that cold for the liquid to go into the gas form.This increased evaporation speed and energy expenditure is also why hikers, skiers, first responders, or anyone staying outside in the cold for extended periods of time should avoid cotton clothing.[ Related: Why 60 degrees in fall feels different than in the spring. ]Cotton is known for causing quick evaporation, explains Arnold. Its a breathable fabric where wools and synthetics prevent some of that evaporation and help keep you warmer when its cold.While meteorologists use a tried and true mathematical formula to calculate the wind chill, charts can also be helpful to make a guess at a glance.CREDIT: National Weather Service/NOAA. Feels-like: heat indexWhile the old adage its not the heat, its the humidity, sounds a bit clich, it is true. Sweating is like the bodys natural air conditioner and helps it cool down when it is warm. However, if there is a lot of moisture in the air, it takes a lot more physical energy for that water to evaporate off our skin.It doesnt allow the evaporation, because you have a combination of heat and humidity together that doesnt allow for evaporative cooling on your body, says Arnold. Its that evaporation process that cools us and if the evaporation process cant happen, it feels lousy.A mathematical formula is also used to calculate the heat index.CREDIT: National Weather Service/NOAA. Dealing with the heat and coldFeels-like temperature can be frustrating, but planning ahead for it can help prevent heat stroke or frostbite. Too much exertion during high heat indexes can be deadly. Planning exertion around these heat indexes and trying to stay in the shade when possible can be helpful. Unlike in the winter, wearing light-colored clothing made of cotton is great for the summer since it allows for more evaporation.That white cotton t-shirt is fantastic in the summertime. When you sweat, itll help cool you off, says Arnold.Hydration is also critical since your body is going to be working extra hard to evaporate the water off of your skin to help cool you down.During the coldest months, the opposite advice is key. Dress in loose and insulating layers that are not too tight and can trap pockets of warm air.You could have five layers on it could be the most insulating fabric ever, but if it is absolutely pressed against each other and super tight, you wont have air in there to actually warm up between those layers and keep you warm, explains Arnold.Covering up exposed bits of skin like the cheek bones or tips of the ears is also critical for extended time outside. Frostbite can settle in in as little as 10 minutes and will make the affected parts of the skin permanently susceptible to infection.One of my favorite sayings is theres no such thing as bad weather, only bad gear. We can survive extreme heat and extreme cold as long as we have the ability and the technology to prepare, says Arnold.This story is part of Popular Sciences Ask Us Anything series, where we answer your most outlandish, mind-burning questions, from the ordinary to the off-the-wall.
