Comprehensive, multinational validation of the PREVENT and SCORE2 cardiovascular risk scores, used in the United States and Europe, respectively, in 44 observational studies and 18 randomized trials, shows similar performance for the two risk scores and generally good performance across geographical regions.
Autism spectrum disorder (ASD) has a complex inheritance pattern and is more common in males. Etiological models suggest that majority of ASD risk is transmitted through common and rare de-novo genetic variation. It has been hypothesized that rare variation could be inherited and therefore contribute to the overall risk-burden in subsequent generations, especially through female lineage in disorders with male-skewed sex-ratios. Here we test this hypothesis using multigeneration information on paternal age, because burden of de-novo mutations has been linked to paternal age, and there is a well-established association between older age of fathers and ASD.

Zhang and colleagues identify astrocytic calcium–cholesterol–AQP4 signaling that drives glymphatic dysfunction in early Alzheimer’s disease (AD). Attenuating this signaling restored glymphatic flow, reduced amyloid burden and improved cognition in young 5xFAD mice only when glymphatic perfusion and lymphatic drainage were intact. These findings position astrocytic metabolic state as a determinant of brain waste clearance and a potential therapeutic target in early AD.

Remote collaboration software tools, such as Zoom or Google Docs, have become essential for teamwork. But they often overlook the fact that people do not all approach collaboration in the same way, according to researchers at North Carolina State University (NCSU).
Scientists report that they have now developed a new human-computer interaction (HCI) method called RemoteCollabEval (RCE) to identify barriers to collaboration and inclusivity, allowing designers and developers to build software features that better support diverse teamwork styles.
The work is part of the broader HCI field, which examines how people use digital systems and how interfaces can be optimized for clarity and ease of use.
“At present, most remote collaboration platforms are evaluated by designers and developers using established HCI inspection methods,” says Sandeep Kuttal, PhD, the principal investigator behind the work and an associate professor of computer science at NCSU. “One of the most widely used inspection methods is a ‘groupware walkthrough,’ where designers essentially play out how a collaborative effort might unfold between two or three hypothetical users. However, these methods typically assume all users behave in similar ways.”
As senior author of a paper, “Equity by Design: A New HCI Method for Surfacing Inclusivity Issues in Remote Collaboration Software,” that will be presented at the ACM Designing Interactive Systems Conference (DIS 2026) in Singapore, from June 13-17, Kuttal notes that “It’s well-established that people from various backgrounds often have different collaboration and communication styles. “Existing HCI inspection methods don’t account for these differences, which limits how inclusive and effective these tools can be. That’s what we set out to address.”
As a first step, the researchers drew on established social science and software engineering research to identify six key personality facets that influence collaborative behavior:
The researchers then created hypothetical users called “personas,” which are detailed representations of different types of users that incorporate descriptions of each of the six facets. These personas allow designers to simulate interpersonal friction and uncover “inclusivity bugs” that might otherwise go unnoticed during standard testing.
“Because we have descriptions of all six facets for each persona, we can incorporate those key characteristics into our assessment of how well a given platform allows for effective collaboration between people of different backgrounds,” explains Kuttal.
The team then modified existing groupware walkthrough methods, requiring designers and developers to explicitly consider these six facets as part of the process and created a specialized walkthrough. This combination of personas that account for personality facets and the specialized walkthrough forms the RCE method.
As a proof-of-concept study, the scientists recruited 29 undergraduate and graduate students and split them into 10 teams. Five teams inspected an existing remote collaboration platform using the conventional Groupware Walkthrough method; the other five teams inspected the same platform using RCE.
“The teams who used the RCE method identified six times more inclusivity issues than the conventional method,” continues Kuttal. “Essentially, RCE did a better job of identifying when conflicting styles would make collaboration between personas difficult. This is important, because identifying these challenges gives designers and developers an opportunity to modify features and user interfaces to improve these remote collaborative platforms. And, ultimately, to improve collaboration itself.
“Because RCE is a standardized, systematic method, it can be used by designers and developers anywhere. It doesn’t require a huge budget, or an expensive research effort. It’s a method that can easily be used to make these platforms better.”

Good morning. Yesterday, the writer Yiyun Li won a Pulitzer Prize for her heartbreaking memoir, “Things in Nature Merely Grow.” Lately, I’ve been reading her short stories. Here’s one for after you’ve read the news, about a health care worker of sorts: “A Sheltered Woman.”
A Monday order from the Supreme Court, signed by Justice Samuel Alito, temporarily restored broad access to mifepristone after a federal appeals court ruling on Friday jeopardized access to the abortion medication at pharmacies or through the mail. The Supreme Court order will remain in effect until the end of the day next Monday, giving both sides time to respond while the court considers the issue. The AP has more details.
Cytokinetics said Tuesday that its drug Myqorzo significantly improved heart failure symptoms and cardiovascular fitness in patients with non-obstructive hypertrophic cardiomyopathy, an inherited heart disorder.
The results, reported in a company press release, achieved the dual efficacy goals of a Phase 3 clinical trial, called ACACIA, with statistical significance.
Cytokinetics is in the early days of Myqorzo’s commercial launch as a treatment for the more severe “obstructive” form of hypertrophic cardiomyopathy, or HCM. The successful outcome of the ACACIA study, if also cleared by regulators, could greatly expand the number of HCM patients eligible for treatment — and boost the drug’s peak sales to $5 billion annually, according to analyst forecasts.
Every few centuries, changes in how information moves reshape how societies govern themselves. The printing press spread vernacular literacy, helping give rise to the Reformation and, eventually, representative government. The telegraph made it possible to administer vast nations like the US, accelerating the growth of the modern bureaucratic state. Broadcast media created shared national audiences, which in turn fueled mass democracy.
We are now in the early stages of another such shift. Faster than many realize, AI is becoming the primary interface through which we form beliefs and participate in democratic self-governance. If left unchecked, this shift could further strain America’s already fragile institutions. But it could also help address long-standing problems, like lagging civic engagement and deepening polarization. What happens next depends on design choices that are already being made, whether we know it or not.
Start with what might be called the epistemic layer—how we come to know things. People are increasingly relying on AI to know what is true, what is happening, and whom to trust. Search is already substantially AI-mediated. The next generation of AI assistants will synthesize information, frame it, and present it with authority. For a growing number of people, asking an AI will become the default way to form views on a candidate, a policy, or a public figure. Whoever controls what these models say therefore has increasing influence over what people believe.
Technology has always shaped the way citizens interact with information. But a new problem will soon arise in the form of personal AI agents, which can change not only how people receive information but how they act on it. These systems will conduct research, draft communications, highlight causes, and lobby on a user’s behalf. They will inform decisions such as how to vote on a ballot measure, which organizations are worth supporting, or how to respond to a government notice. They will, in a meaningful sense, begin to mediate the relationship between individuals and the institutions that govern them.
We’ve already seen with social media what happens when algorithms optimize for engagement over understanding. Platforms do not need to have an explicit political agenda to produce polarization and radicalization. An agent that knows your preferences and your anxieties—one shaped to keep you engaged—poses the same risks. And in this case the risks may be even more difficult to detect, because an agent presents itself as your advocate. It speaks for you, acts on your behalf, and may earn trust precisely through that intimacy.
Now zoom out to the collective. AI agents and humans could soon participate in the same forums, where it may be impossible to tell them apart. Even if every individual AI agent were well-designed and aligned with its user’s interests, the interactions of millions of agents could produce outcomes that no individual wanted or chose. For example, research shows that agents displaying no individual bias can still generate collective biases at scale. And setting aside what agents do to each other, there is what they do for their users. A public sphere in which everyone has a personalized agent attuned to their existing views is not, in aggregate, a public sphere at all. It is a collection of private worlds, each internally coherent but collectively inhospitable to the kind of shared deliberation that democracy requires.
Taken together, these three transformations—in how we know, how we act, and how we engage in collective governance—amount to a fundamental change in the texture of citizenship. In the near future, people will form their political views through AI filters, exercise their civic agency through AI agents, and participate in institutions and public discussions that are themselves shaped by the interactions of millions of such agents.
Today’s democracy is not ready for this. Our institutions were designed for a world in which power was exercised visibly, information traveled slowly enough to be contested, and reality felt more shared, if imperfectly. All of this was already fraying long before generative AI arrived. And yet this need not be a story of decline. Avoiding that outcome requires us to design for something better.
On the informational layer, AI companies must ramp up existing efforts to ensure that models’ outputs are truthful. They should also explore some promising early findings that AI models can help reduce polarization. A recent field evaluation of AI-generated fact checks on X found that people with a variety of political viewpoints deemed AI-written notes more helpful than human-written ones. The paper is yet to be peer-reviewed, but that is a potentially revolutionary finding: AI-assisted fact-checking may be able to achieve the kind of cross-partisan credibility that has eluded most manual human efforts. Greater understanding of and transparency about how models make these assertions and prioritize sources in the process could help build further public trust.
On the agentic layer, we need ways to evaluate whether AI agents faithfully represent their users. An agent must never have an agenda of its own or misrepresent its user’s views—a technically daunting requirement in domains where users may have not explicitly stated any preferences. But faithful representation also cannot become an accessory to motivated reasoning. An agent that refuses to present uncomfortable information, that shields its user from ever questioning prior beliefs or fails to adjust to a change of heart, is not acting in the person’s best interest.
Finally, on the institutional level, policymakers should hurry to harness AI’s potential to make governance more responsive and legitimate. Several states and localities are already using AI-mediated platforms to conduct democratic deliberation at scale, building on research showing that AI mediators can help citizens find common ground. As agents become increasingly common participants in public input processes—and there is already evidence that bots are skewing those processes—identity verification for both humans and their agentic proxies must be built in from the start.
What is needed is a new generation of democratic infrastructure, technological and institutional, built for the world that is actually here. Failing to design for democratic outcomes, in a domain this consequential, means designing for something else. And the history of unaccountable power does not leave much room for optimism about what that something else tends to be.
