A Jagged1-regulated hybrid-EMT state identifies pancreatic cancer stem cells
Lan et al. show that a subset of CD9hi tumor-initiating cells in pancreatic cancer exhibits hybrid-EMT features and possesses enhanced self-renewal and differentiation capacities. Depletion of these cells or blockage of Jagged1-Notch signaling impairs tumorigenesis and cellular heterogeneity, revealing a vulnerability for pancreatic cancer.

Panpsychism and Explaining Consciousness — TED Talk — David Chalmers
Our consciousness is a fundamental aspect of our existence, says philosopher David Chalmers: “There’s nothing we know about more directly… but at the same time it’s the most mysterious phenomenon in the universe.” He shares some ways to think about the movie playing in our heads.
Single-Shot Parity Readout of a Minimal Kitaev Chain: A Breakthrough in Majorana Qubits
In a major technical leap published in Nature on February 11, 2026, an international research team led by QuTech (Delft University of Technology) and the Spanish National Research Council (CSIC) has demonstrated the first single-shot, real-time readout of the quantum information stored in Majorana qubits. This achievement addresses the “readout problem”—the long-standing experimental hurdle of measuring a non-locally distributed quantum state without compromising its inherent topological protection.
The study, titled “Single-shot parity readout of a minimal Kitaev chain,” utilizes a novel quantum capacitance technique to sense the global state of a “Kitaev minimal chain.” By constructing a bottom-up nanostructure of two semiconductor quantum dots coupled via a superconductor, the team successfully generated Majorana zero modes (MZMs) in a controlled, modular fashion. This “Lego-like” approach allowed the researchers to discriminate between the even and odd parity states (the 0 and 1 of the qubit) in real-time, effectively unlocking the “safe box” of topological information.
Brain Volumes After Hypertensive Pregnancy and Postpartum Blood Pressure Management: A POP-HT Randomized Clinical Trial Imaging Substudy
In a randomized clinical trial of women with prior HypertensivePregnancy, physician-optimized postpartum blood pressure self-management was associated with larger white matter brain volumes at 9 months compared with usual care.
Women with a history of preeclampsia receiving usual care had smaller volumes in subcortical regions (putamen, accumbens, pallidum) than those with gestational hypertension, differences that were not observed in the intervention group.
This randomized clinical trial indicates that a postpartum blood pressure management intervention after hypertensive disorders of pregnancy may be associated with favorable brain structure during the first year post partum. The intervention was linked to larger white matter volumes across women with hypertensive pregnancy (gestational hypertension and preeclampsia). In addition, women with a history of preeclampsia in the usual care arm showed smaller subcortical brain volumes at 6 to 9 months post partum than those with gestational hypertension; these differences were not evident among women in the intervention arm.
Both women with preeclampsia and gestational hypertension experience high blood pressure during pregnancy that frequently persists post partum.28 Lower white matter integrity has been reported from the peripartum period into later life.3,12,29 Hypertension-related white matter injury30,31 is associated with slower processing speed, executive dysfunction, and memory impairment.31 Although cognitive impact may not be obvious in the early postpartum period, white matter changes predict later cognitive decline and dementia,32 and converging longitudinal evidence suggests that reductions in white matter volume and integrity track cognitive decline, supporting the interpretation that better-preserved white matter is beneficial.33
Whether postpartum white matter changes are preventable or reversible had not been investigated. In this randomized clinical trial, a short-term blood pressure control intervention was associated with larger brain volumes several months later, when most participants were no longer taking antihypertensive medication. This is consistent with the postpartum period as a critical window for pregnancy-associated brain volume and blood pressure changes. Because baseline brain MRIs were not acquired, we cannot distinguish recovery of pregnancy-related changes from a slower postpregnancy decline relative to usual care.
Study of 65,000 college students links 16 hours a week on social media to higher loneliness
More than half of college students are lonely—and those who use social media the most are particularly likely to feel isolated, a study of tens of thousands of 18 to 24-year-olds in the US shows. Just 16 hours a week—two or so hours a day—on social media was linked with higher odds of loneliness, reports a paper in the Journal of American College Health.
The study’s authors said that academic institutions should educate students on the effects of social media use and encourage them to set time limits.
Researcher Dr. Madelyn Hill, now an assistant professor at Ohio University, who led the study while completing her doctoral work in University of Cincinnati’s School of Human Services in spring 2025, explains, We know that people who are lonely are more likely to become depressed. We also know that those who are lonely are more likely to die early.
