Circadian rhythm drives metabolic dysfunction in fat cells, study finds

Northwestern Medicine scientists led by Joseph Bass, MD, Ph.D., the Charles F. Kettering Professor of Endocrinology and Metabolism and director of the Center for Diabetes and Metabolism, have discovered how disruptions in the circadian rhythm impair metabolic function in fat cells, providing new insights into the molecular mechanisms that cause obesity and metabolic disease, according to a recent study published in Nature Metabolism.

“It’s not simply the accrual of excess fat that leads to disease. It’s a change in the actual function and the capacity of the energy center within the cell to work properly,” said Bass, who is also chief of Endocrinology, Metabolism and Molecular Medicine in the Department of Medicine and a member of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University.

The circadian rhythm is the body’s own internal 24-hour clock that regulates the sleep-wake cycle, hormone levels and metabolism, among other systems throughout the body.

Perspectives on an Emerging 18TH Sdg Articulation — an Sri Side Event at Copuos Legal Subcommittee

(SRI) will organize a high-level side event during the COPUOS Legal Subcommittee on 16 April 2026 at UNOOSA (Vienna), proposed and convened by Dr. Gülin Dede, titled “Operationalising Space as a Cross-Cutting Enabler of Sustainable Development: Perspectives on an Emerging 18th SDG Articulation.”

The session will bring together legal, policy, industry, and Global South perspectives to examine how outer space is evolving from a sectoral domain into a critical enabling infrastructure for the 2030 Agenda, while simultaneously requiring stewardship as an environment in its own right.

Positioned as an early contribution to shaping how space sustainability is framed within the broader UN system, the event will also be broadcast by the United Nations, extending its reach beyond the room to a global audience.

Unveiling the epitope repertoires and protective roles of MERS-CoV-specific T cells in mice

Zhen Zhuang et al. identify MERS-CoV-specific T cell epitope repertoires in C57BL/6 and BALB/c mice and demonstrate that ORF4b208-specific CD4+ and ORF5167-specific CD8+ T cells are polyfunctional effectors and protective in MERS-CoV infection.

Seven subsets, two fates: mouse γδ T cells in cancer immunity

Mouse γδ T cells in cancer immunity.

Mouse γδ T cells are not all the same; rather, they comprise seven subsets that influence progression in several cancer types.

Antitumor γδ T cell subsets can be tissue-resident or circulating cells, which generally rely on glycolysis for energy production, and they mediate cancer cell death via interferon-gamma or orchestration of antitumor immunity.

Protumor γδ T cell subsets use lipids for energy production, and they promote primary tumor growth and metastasis through the production of interleukin17A to modulate the behavior of myeloid cells sciencenewshighlights ScienceMission https://sciencemission.com/Seven-subsets,-two-fates

The importance of γδ T cells in cancer, as defenders against tumorigenesis, was established more than 2 decades ago. Since that time, research using mouse models of cancer has brought to light a nonuniform view of tumor-associated γδ T cells by providing granularity into the role of individual γδ T cell subsets in specific cancer types. In this review, we discuss data that highlight the unique contributions of Vγ1+, Vγ4+, Vγ5+, Vγ6+, and Vγ7+ cells throughout cancer progression. We delve into their responses to tumors, including both protective and pathogenic functions. We examine how the mechanisms by which these mouse immune cell subsets shape tumor development and spread can be exploited for therapeutic purposes in people with cancer.

Human brain operates near, but not at, the critical point

A recent study published in Physical Review Letters reveals that many widely used signatures of criticality in brain data may be statistical artifacts. They propose a more robust framework that, when applied to whole-brain fMRI data, confirms the brain operates near, but not exactly at, a critical point.

Neuroscientists have long found the idea fascinating—that the brain operates near a “critical point,” a phase transition between stable and chaotic dynamics. Theory suggests this sweet spot enhances computational flexibility, dynamic range, and sensitivity to inputs. Evidence has mounted over the years from neural recordings showing approximate scale invariance and power-law behavior across spatiotemporal scales.

The concept has even influenced AI, particularly reservoir computing, where networks near the “edge of chaos” tend to perform best. However, the field faces a persistent concern: are these criticality signatures intrinsic to the brain’s recurrent dynamics, or do external inputs and data limitations shape them?

New Carbon Nanotube Coating Could Supercharge 6G Technology

Ultrathin nanotube films absorb terahertz waves, boosting 6G performance and enabling advanced shielding and medical applications. Researchers at Skoltech, working with colleagues from KTH Royal Institute of Technology in Sweden, have developed a key technology that could support future 6G commun

This video tests three real generation-ship proposals against five brutal constraints: gravity, radiation, closed-loop life support, cultural continuity across 400 years, and the selection problem — choosing who gets to go. We break down Chrysalis (a 58 km modular ship that sheds stages like a rocket), Proximum (a civilization carved inside an asteroid), and WFP (a self-assembling micro-city based on MIT research). Along the way we confront governance without a homeworld, genetic bottlenecks, generational memory loss, and why shared rituals might matter more than engine specs. The answer isn’t one ship — it’s three radically different philosophies of what it means to be human in deep space.

Divergent Roles of PI3K Isoforms in PTEN-Deficient Glioblastomas

(Cell Reports 32, 108196; September 29, 2020)

As this paper was originally published on September 29, 2020, Figure 3C showed similar imagery across western blot analyses for αTubulin and pAkt473. This error was caused by an inadvertent swap of two loading control panels of αTubulin and Akt that appeared during figure assembly. The corrected figure can be seen below.

The error and correction thereof do not affect the results or conclusions of the study. The authors apologize for any confusion caused.
