Why AI is becoming a powerful tool in cancer drug discovery

This Perspective reviews how AI is moving drug discovery from long, costly experimental pipelines toward earlier clinical translation, with an AI-designed TNIK inhibitor trial serving as an important proof-of-feasibility reference point. It argues that precision oncology could benefit from AI-driven integration of multi-omics, federated learning, and adaptive trial design, but only if validation, fairness, interpretability, and regulatory alignment improve.

Study finds long COVID leaves a distinct immune signature in the blood

Researchers identified a small panel of inflammatory and neurology-related blood proteins that may help distinguish long COVID from recovery or no prior infection, while also showing that booster vaccination did not appear to worsen these protein responses in this cohort. The study also found that immune responses after reinfection differed from those seen after the first SARS-CoV-2 infection, suggesting altered long-term immune behavior in some previously infected individuals.

SARS-CoV-2 rarely reaches first-trimester placentas but still disrupts early pregnancy immunity

Researchers analyzing 761 first-trimester pregnancies found that SARS-CoV-2 was rarely detected in placental tissues, suggesting in utero transmission early in pregnancy is uncommon. However, maternal infection was linked to immune dysregulation at the maternal-fetal interface, altered trophoblast signaling, and inflammatory changes that could affect placental development.

Postpartum Medicaid expansion improved coverage but showed limited care changes

The federal policy requiring states to keep Medicaid beneficiaries enrolled during the COVID-19 pandemic extended postpartum Medicaid coverage nationwide and sharply increased the number of individuals remaining insured after childbirth, according to a Rutgers Health researcher.

Antidepressant fluvoxamine reduces long COVID fatigue in clinical trial

A randomized placebo-controlled trial found that fluvoxamine, a low-cost antidepressant, reduced fatigue and improved quality of life in adults with long COVID, offering one of the first evidence-based medication options for this persistent condition. In contrast, metformin did not provide meaningful benefit for established long COVID fatigue, highlighting fluvoxamine as the more promising treatment candidate in this study.

CDC tracks SARS-CoV-2 BA.3.2 global rise and finds early signals in U.S. wastewater

CDC surveillance shows that the highly divergent SARS-CoV-2 variant BA.3.2 spread to at least 23 countries and was detected in U.S. travelers, patients, airplane wastewater, and wastewater samples across multiple states. The report highlights wastewater and traveler-based genomic surveillance as early warning tools while noting that BA.3.2 has immune-evasion potential but has not rapidly displaced other circulating lineages.

COVID-19 learning losses could deepen class gaps for years

COVID-19 school closures are projected to reduce educational attainment and weaken intergenerational mobility, with children from less advantaged backgrounds facing the greatest losses. The paper’s simulations suggest that unequal access to continued learning during the pandemic could deepen educational inequality and reverse mobility gains, especially in the absence of remedial recovery measures.

Researchers use AI to reveal the true scale of COVID-19 mortality in the US

A machine learning model applied to US death certificate data estimated that over 155,000 COVID-19 deaths were unrecognized between March 2020 and December 2021, suggesting total mortality was about 19% higher than official counts. These undercounted deaths disproportionately affected marginalized populations, including racial minorities, lower-income groups, and residents of the Southern United States.

Scientists identify common symptom patterns in post-COVID-19 vaccination syndrome

A registry study across 14 Japanese clinics analyzed 179 cases of post-COVID-19 vaccination syndrome (PCVS) and identified 493 adverse events affecting multiple organ systems. Most symptoms appeared within 90 days, but some occurred much later, highlighting the need for continued vaccine safety monitoring and better clinical frameworks for persistent post-vaccination symptoms.

Study reveals why US life expectancy gains stalled after decades of progress

A PNAS study analyzing US mortality from 1979 to 2023 reveals that life expectancy stagnation reflects both worsening outcomes in post-1950 birth cohorts and a broad mortality deterioration beginning around 2010. Cardiovascular mortality slowdowns, rising external causes, and cohort-specific patterns help explain the persistent decline in longevity gains.
