AMERIKAN AI IS RACIST

Medical AI systems failing to disclose inaccurate race, ethnicity information



University of Minnesota


The inaccuracy of race and ethnicity data found in electronic health records (EHRs) can negatively impact patient care as artificial intelligence (AI) is increasingly integrated into healthcare. Because hospitals and providers inconsistently collect such data and struggle to accurately classify individual patients, AI systems trained on these datasets can inherit and perpetuate racial bias.

In a new publication in PLOS Digital Health, experts in bioethics and law call for immediate standardization of methods for collection of race and ethnicity data, and for developers to warranty race and ethnicity data quality in medical AI systems. The research synthesizes concerns about why patient race data in EHRs may not be accurate, identifies best practices for healthcare systems and medical AI researchers to improve data accuracy, and provides a new template for medical AI developers to transparently warrant the quality of their race and ethnicity data

Lead author Alexandra Tsalidis, MBE, notes that “If AI developers heed our recommendation to disclose how their race and ethnicity data were collected, they will not only advance transparency in medical AI but also help patients and regulators critically assess the safety of the resulting medical devices. Just as nutrition labels inform consumers about what they’re putting into their bodies, these disclaimers can reveal the quality and origins of the data used to train AI-based health care tools.”

“Race bias in AI models is a huge concern as the technology is increasingly integrated into healthcare,” senior author Francis Shen, JD, PhD, says. “This article provides a concrete method that can be implemented to help address these concerns.”

While more work needs to be done, the article offers a starting point suggests co-author Lakshmi Bharadwaj, MBE. “An open dialogue regarding best practices is a vital step, and the approaches we suggest could generate significant improvements."

The research was supported by the NIH Bridge to Artificial Intelligence (Bridge2AI) program, and by an NIH BRAIN Neuroethics grant (R01MH134144).

Mysterious fungi: Researchers pinpoint hotspots of “dark taxa” across Earth’s underground ecosystems



New study finds that 83% of ectomycorrhizal fungi are known only by their DNA sequences that can’t be linked to named or described species, posing problems for conservation.

Mycorrhizal fungi help regulate Earth’s climate and ecosystems by forming underground networks that provide plants with essential nutrients, while drawing carbon deep into soils. Scientists and conservationists have been racing to find ways to protect these underground fungi, but they keep finding dark taxa – species that are known only by their DNA sequences that can’t be linked to named or described species.

It is estimated that only 155,000 of the roughly 2-3 million fungal species on the planet have been formally described. Now, a review published in Current Biology on June 9 shows that as much as 83% of ectomycorrhizal species are so-called dark taxa. The study helps identify underground hotspots of unknown mycorrhizal species occurring in tropical forests in southeast Asia and Central and South America, tropical forests and shrublands in central Africa, Sayan montane conifer forests above Mongolia, and more. This discovery has serious implications for conservation.

Names are important in the natural sciences. Traditionally, once a species is described, it is given a binomial – a name made of two Latin words that describe the species and genus. These names are used to categorize fungi, plants, and animals, and are critical identifiers for conservation and research. Most mycorrhizal fungi in the wild are found using environmental DNA (eDNA) -- genetic material that organisms shed into their surroundings. Scientists extract fungal eDNA from soil and root samples, sequence that DNA, and then run those sequences through a bioinformatics pipeline that matches a sequence with a described species. For dark taxa there are no matches – just strings of As, Gs, Cs, and Ts.

“We are a long way out from getting all fungal DNA sequences linked to named species,” says lead author Laura van Galen, a microbial ecologist working with the Society for the Protection of Underground Networks (SPUN) and ETH University, Switzerland. “Environmental DNA has enormous potential as a research tool to detect fungal species, but we can’t include unnamed species in conservation initiatives. How can you protect something that hasn’t yet been named?”

Ectomycorrhizal fungi are one of the largest groups of mycorrhizal fungi and form symbiotic partnerships with about 25% of global vegetation. Ectomycorrhizal fungi facilitate the drawdown of over 9 billion tons of CO2 annually (over 25% of yearly fossil fuel emissions) and help Earth’s forests function by regulating nutrient cycles, enhancing stress tolerance, and even breaking down pollutants.  

The researchers’ work has uncovered that dark taxa of ectomycorrhizal fungi are not spread evenly across the Earth. “There are hotspots of high dark taxa around the globe, but particularly they are concentrated in tropical regions in Southeast Asia and parts of South America and Africa,” says van Galen. “Most of the research on ectomycorrhizal fungi has been focused in the North, but mid-latitude and southern-hemisphere regions show signs of being home to many unknown species. This means there is a mismatch in resources and funding. We need to bridge this gap and facilitate more tropical researchers and those from southern-hemisphere regions to focus on identifying these super-important fungi.”

The researchers have suggestions of how we can start bringing these fungi out of the shadows. “One way to reduce the dark taxa problem is to collect, study and sequence mushrooms and other fungi,” says co-author Camille Truong, a mycorrhizal ecologist at SPUN and research scientist at the Royal Botanic Gardens Victoria in Australia. “Conversely, there are mushrooms that have been sitting for decades in collections of botanical gardens. These should be urgently sequenced so that we can, hopefully, start matching them up with some of these dark taxa.”

Many of the unidentified fungal species are associated with plants that are themselves endangered. “We're at risk here,” says van Galen. “If we lose these host plants, we might also be losing really important fungal communities that we don’t know anything about yet.”

The technology is available – what’s missing is attention. “We really need to pay so much more attention to fungi in the soil so that we can understand the species and protect them and conserve them before we lose them,” says van Galen. The team hopes that conservation organizations will use the information to protect hotspots of underground biodiversity, even if these species remain nameless.


The Society for the Protection of Underground Networks (SPUN) is a non-profit scientific research organization with a mission to map and preserve Earth’s fungal networks. In collaboration with researchers and local communities, SPUN is accelerating efforts to protect the underground ecosystems largely absent from conservation and climate agendas.

It’s not the game, it’s the group: Sports fans connect the most over rituals

PATRIARCHAL SUBLIMATION OF WAR


University of Connecticut




University of Connecticut professor of anthropology Dimitris Xygalatas is a scientist and self-declared rational thinker. But he’s also a lifelong soccer fan, and he fully admits that when his Greek home team finally won their league in 2019, he cried tears of joy.

“Not what you might call a rational organism’s behavior,” he jokes.

But his reaction is in keeping with his latest study, to be published online Monday, June 9, in the Proceedings of the National Academy of Sciences, which shows that the intense feelings of joy, unity, and excitement that fans experience surrounding sports can be less about the game and more about the ritual of coming together.

“Rituals are the kinds of things that, at first glance, don't make any sense in terms of human behavior, but are deeply meaningful to people,” says Xygalatas.

With the cooperation of a die-hard Brazilian soccer (actually, it’s “football,” Xygalatas grudgingly reminds us Americans) fan club, Xygalatas and his team tracked the physiological arousal of fans before, during, and after a state championship final in Minas Gerais between local rival teams.

Using wearable heart monitors, they measured the emotional reactions of fans during the ritual of Rua de Fogo (Street of Fire), during which crowds gather near the stadium to welcome the team’s bus. As it arrives, fans light flares, smoke bombs, and fireworks, wave flags, and chant to boost team morale and unify supporters.

The scientists outfitted participants with EKG monitors hidden beneath their clothing. The devices measured heart rate fluctuations, which is a proxy for emotional arousal, as fans participated in the pre-game celebration, entered the stadium, and watched the match unfold.

What they found was striking: The levels of shared excitement, or what the scientists call “collective effervescence,” peaked not during the game, but during the pre-game fan rituals.

Only when the home team scored a goal did those physiological markers exceed the emotional high of the pre-match gathering.

“What we see is that, in fact, the pre-game ritual generates more emotional synchrony than the game itself,” Xygalatas says. “There’s a single moment in the entire game when they have more collective emotional synchrony than the pre-game ritual, and that’s when they scored a goal.”

The findings underscore Xygalatas’ broader work to understand how ritual shapes human behavior and identity.

“Rituals are the kinds of things that, at first glance, don't make any sense in terms of human behavior, but are deeply meaningful to people,” he says.

Xygalatas' past research has taken him to remote firewalking ceremonies and intense religious festivals. But soccer, he says, offers a unique laboratory: It's a global obsession that’s rich in ritual and pageantry, but largely free from political or religious ideology.

The physiological data from his latest research showed that this ritualistic gathering — something that occurred before a single ball was kicked — produced sustained arousal levels comparable to the game itself.

“People attribute a lot of meaning to sports,” Xygalatas says. “Sports generate billions and billions of dollars globally, and they take up so much of people's attention. And the reason they do that is not just because of what's happening on the pitch. It’s because of these ritualized interactions that occur among the fans.”

The implications, the paper argues, extend beyond sports. Ritualized group behaviors like concerts, religious ceremonies, or political rallies may powerfully shape people’s emotions and even their beliefs.

“By going to these events, we're actually shaping our beliefs,” he says. “So sports is not just an excuse for people to get together. It’s a driver of identity.”

Xygalatas speaks from experience. As a young man growing up in Thessaloniki, Greece, he was a member of a soccer fan club. One day, while wearing his team’s scarf in the wrong neighborhood, he was ambushed by four men and brutally attacked, an incident that echoes the fatal beating of a 19-year-old in his hometown years later, also over team allegiance.

“I felt a blow to my head from behind, and next thing I knew, there were four men beating me, kicking me on the head, everywhere,” remembers Xygalatas. “The reason I was able to escape is that another group of men was turning the corner, wearing my insignia, so they chased them away.”

Football, he says, is the only sport that regularly leads to deadly violence, a fact that leagues and governing bodies like FIFA should take seriously.

He says it’s in soccer clubs’ best interest to strike a balance between building loyalty, which Europeans and South Americans are excellent at doing, and making it safe for people to participate in.

Still, Xygalatas is clear that he’s not advocating for less passion. He hopes his work helps people understand why they care so deeply in the first place.

“If we look at what makes us human, we realize that it's our ability and our need to derive meaning from things that seem meaningless,” he says.

Xygalatas’ co-authors on this paper are Mohammadamin Saraei, graduate student in the UConn Department of Psychological Sciences; Vitor Leandro da Silva Profeta, professor in the Departamento de Educação Física at the Universidade Federal de Minas Gerais; and Gabriela Baranowski-Pinto, professor in the Department of Human Movement Sciences at the Universidade do Estado de Minas Gerais.

 

Vital connections between journalists and whistleblowers under increasing pressure



University of Exeter




Investigative journalists are facing severe challenges and threats, and their vital connections with whistleblowers are under increasing pressure, researchers have said.

Legal intimidation is having a "chilling effect" and those engaged in crime and security journalism are encountering extreme risks.

Experts have discussed their significant concerns about the perils many journalists face in their commitment to uncovering truth, from pervasive state surveillance to targeted prosecution and even espionage operations by hostile states, during a special event.

At the Law and Society Association event held in Chicago, the founding members of the Economic Crime and Corporate Compliance collaborative research network (CRN41), featuring Diane Ring (Boston College) and Costantino Grasso (University of Exeter), organized several sessions focused on these critical issues.

Workshops covered the indispensable role investigative journalism plays in safeguarding democracy and ensuring robust accountability, and how reporters serve as a crucial, often frontline, mechanism for unmasking corruption, unethical practices, and potential wrongdoing, particularly by powerful entities that might otherwise operate in secrecy.

Researchers discussed the calculated abuse of legal processes through Strategic Lawsuits Against Public Participation (SLAPPs), which are specifically designed to intimidate, exhaust financial resources, and ultimately silence their reporting.

The overarching aim of CRN41 is to create a global forum for research and collaboration on economic crime and the development of measures by institutions and businesses to mitigate organizational risks and misconduct. Researchers have established a long-term dialogue on traditional economic crimes such as corruption, tax evasion, money laundering, fraud, insider trading, terrorism financing, and cybercrime as well as interconnected criminal practices such as environmental crimes and corporate homicide.

Research includes also socially harmful organizational behaviours, including unethical lobbying, tax abuses, and environmental degradation. There is a special focus on the role of transparency, whistleblowing, and emerging technologies.

During the Chicago event the critical role of whistleblowing was further explored in depth during the roundtable "Whistleblowing in Democracy: Safeguarding Justice, Transparency, and Organizational Integrity". This session explicitly examined how whistleblowers contribute to justice and transparency, echoing the goals of investigative reporting.

Broader themes of accountability and the mechanisms for uncovering wrongdoing, central to investigative journalism, were discussed in other sessions like "Beyond Profit: Redefining Corporate Accountability in a Globalized World," where participants discussed holding corporations responsible for their impacts and the crucial role of litigation and enforcement.

The CRN41 brought together experts from several institutions spanning 10 countries. It featured  contributions from academics and practitioners from the nations include the United States, the United Kingdom, Australia, Italy, and Brazil. Academics were from institutions including the University of Exeter, Boston College, University of Oklahoma, Flinders University, Luiss University, Sant'Anna School of Advanced Studies, University of São Paulo, and non-academic bodies like the Office of the Prosecutor in Naples and Whistleblowers of America.

Dr Grasso presented his ongoing research on the weaponization of legal systems to silence truth-tellers. His research investigates how legal mechanisms may be misused to suppress dissent through SLAPPs, a phenomenon explored in depth using the Carole Cadwalladr v. Arron Banks libel case as a key illustrative study. His work examines how SLAPPs exploit legal processes to intimidate critical voices, analyses vulnerabilities in English libel law, and scrutinizes the evolution of the public interest defence alongside the efficacy of current UK anti-SLAPP legislative reforms. His research advocates for robust measures to protect civic courage and freedom of expression from such legal intimidation.

 

Anthropologists map Neanderthals’ long and winding roads across Europe and Eurasia



Computer simulations of pathways point to how ancient migrations shaped human history

Computer simulated paths of Neanderthal dispersals demonstrate they could have reached the Altai Mountains in Siberia within 2,000 years during warm climatic conditions in one of two ancient time periods—MIS 5e (approximately 125,000 years ago) or MIS 3 (approximately 60,000 years ago)—as demonstrated by the three different possible paths shown here. These paths follow a northern route through the Ural Mountains and southern Siberia, often intersecting with known archaeological sites from the same time periods.

Recent scholarship has concluded that Neanderthals made a second major migration from Eastern Europe to Central and Eastern Eurasia between 120,000 and 60,000 years ago. But the routes they took have long been a mystery—primarily because there are few archaeological sites connecting the two regions. 

In a new analysis, a team of anthropologists—using computer simulations—has offered a map of possible pathways, which concludes Neanderthals likely used river valleys as natural highways and traveled during warmer periods to move approximately 2,000 miles (3,250 km) in less than 2,000 years. 

“Our findings show that, despite obstacles like mountains and large rivers, Neanderthals could have crossed northern Eurasia surprisingly quickly,” explains Emily Coco, who began the study as a New York University doctoral student and is now a postdoctoral researcher at Portugal’s University of Algarve. 

The research, which appears in the journal PLOS One, was conducted with Radu Iovita, an associate professor at NYU’s Center for the Study of Human Origins

“These findings provide important insights into the paths of ancient migrations that cannot currently be studied from the archaeological record and reveal how computer simulations can help uncover new clues about ancient migrations that shaped human history,” observes Coco. 

In building their simulation of Neanderthals’ two-millennia journey, Coco and Iovita considered the elevation of the terrain, reconstructed ancient rivers, glacial barriers, and temperature to model movement decisions of individuals—an approach similar to that used to model both modern human and animal movement, but not previously applied to Neanderthals. 

The authors find possible migration routes in two ancient periods—Marine Isotope Stage 5e [MIS 5e] (beginning approximately 125,000 years ago) and Marine Isotope Stage 3 [MIS 3] (beginning approximately 60,000 years ago)—marked by warmer temperatures and therefore more suitable for movement. 

Computer simulations, conducted on the NYU Greene Supercomputer Cluster, indicated that Neanderthals could have reached Eurasia’s Siberian Altai Mountains within 2,000 years during either MIS 5e or MIS 3 using multiple possible routes that all follow the same basic northern path through the Ural Mountains and southern Siberia, often intersecting with known archaeological sites from the same time periods. 

The authors add that the study sheds light on Neanderthal interactions with other ancient human groups. Specifically, their routes would have taken them into areas already occupied by Denisovans—consistent with existing evidence of interbreeding between the two species.

“Neanderthals could have migrated thousands of kilometers from the Caucasus Mountains to Siberia in just 2,000 years by following river corridors,” says Iovita. “Others have speculated on the possibility of this kind of fast, long-distance migration based on genetic data, but this has been difficult to substantiate due to limited archaeological evidence in the region. Based on detailed computer simulations, it appears this migration was a near-inevitable outcome of landscape conditions during past warm climatic periods.”
