How AI is distorting online research, from polls to public policy‎

Artificial intelligence is increasingly able to simulate human behavior and answer online surveys and political polls, putting the reliability of survey-based research at risk. Consequences can be serious, not only for science and research—online surveys are a cornerstone of modern social-science research—but also for policy and participation of people in democratic processes, as surveys are widely used in political polls.

Reshaping the future of urban experimentation for lasting change‎

Cities everywhere are running experiments to respond to climate change and sustainability challenges, such as new mobility trials, energy pilots, green space projects, circular economy approaches, and more. New research from the Monash Business School has found that many of these efforts stay small, stay siloed, or fade when funding ends.

Why Valentine's Day can bring up big feelings even when things seem fine‎

Valentine's Day is widely associated with romance and celebration, but research shows the holiday also can heighten emotions and expectations in close relationships. For some, it can bring added pressure around how love is expressed. For others, particularly those navigating loss or transition, it can underscore feelings of absence or uncertainty.

Economic, educational and gender inequities can contribute to problematic social media use among teens‎

A new McGill study suggests that problematic social media use among teens is in part related to broader social inequalities. Zékai Lu, a Ph.D. student in McGill's Department of Sociology and author of the study, had set out to determine whether problematic social media use is driven mainly by individual traits or whether the social environment of the country a teen lives in also plays a significant role.

Releasing pollack near catch depth may raise survival from 56% to 80%‎

During 2026, new legislation—the result of an agreement between the UK Government and the European Union—is planned to come into force for recreational pollack fishing that limits catches to three fish per angler per day. It will result in more fish being released after they are caught, but new research has suggested changing how that release happens could have a marked difference to the fisheries' long-term sustainability.

Baring the 'silent violence' of Philippine jails‎

Conversations about Philippine jail congestion often begin and end with statistics: thousands of case backlogs, cells built for 50 crammed with 200 bodies, and facilities straining at 300% to 400% beyond capacity. Yet these numbers barely capture the everyday human cost of overcrowding.

Rolling out the carpet for spin qubits with new chip architecture‎

Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits. The platform, called QARPET (Qubit-Array Research Platform for Engineering and Testing) and reported in Nature Electronics, allows hundreds of qubits to be characterized within the same test-chip under the same operating conditions used in quantum computing experiments.

How redox reactions drive bacteria's Na⁺-NQR sodium pump‎

The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions, the process of exchanging electrons between materials, it powers the transportation of sodium ions across the membrane, supporting the growth of the bacteria.

Ambitious climate action could save 1.32 million lives a year by 2040‎

Ambitious climate action to improve global air quality could save up to 1.32 million lives per year by 2040, according to a new study. The research, led by Cardiff University, shows how developing countries rely heavily on international cooperation to see these benefits, because much of their pollution originates outside their borders. The first-of-its-kind study analyzed these cross-border pollution "exchanges" for nearly every country—168 in total.

Urgent need for school-housing partnerships to support students facing housing instability, according to study‎

Housing instability, often invisible to schools until it begins to disrupt attendance, learning, or mental health, is a growing challenge for families with school-age children, according to new research. A policy scan led by USC Rossier Professor Huriya Jabbar, Harmonizing Systems to Reduce Eviction and Homelessness: An Environmental Scan of Innovative School-Housing Partnerships, examined how education systems and housing agencies across the country are working together to support students whose families face eviction, displacement, or unaffordable housing—and where critical gaps remain.
