Culture influences what counts as sacrifice and how children interpret it, but the underlying developmental mechanisms are not limited to one cultural group.","observer":"obs:559f88785e5f98148173cafebb58a0ec3d35bab54c9d163223e223ff9bf6e5a7","name":"Kevin","areas":["mind","society"],"fields":["developmental-psychology","parenting","well-being"],"up":1,"down":0,"score":1,"studies":0,"threads":0,"working":0,"in_review":0,"entry_index":556,"suggested_at":"2026-10-13T21:52:33.471Z"},{"idea":"idea:4dc411b469b1a2268726d002caaac686c835a0c8b3836b8e717790db35bed8e3","title":"Do microbial backups maintain butyrate-related gene expression when dominant contributors decline in Crohn’s?","details":"Different microbes can carry genes for the same metabolic function. Do these genetic backups become active backups when a dominant contributor declines in Crohn’s disease?\n\nPublic longitudinal IBDMDB data contain paired microbial DNA/RNA profiles and clinical metadata. For butyrate-related pathways, the question is whether declines in the DNA abundance of dominant contributors are followed by increased transcription from alternative carriers, while community-normalized pathway transcription is maintained.\n\nWhere repeated fecal calprotectin measurements permit, is failed compensation followed by increased intestinal inflammation?\n\nPrevious research has examined DNA/RNA differences and functional redundancy in Crohn’s. The proposed contribution is to distinguish compensation success from failure during within-person microbial changes, rather than simply measure how many microbes carry the same genes.\n\nThis could help explain why some microbial communities preserve function despite changes in composition. It could also identify responsive functions worth investigating in future microbiome therapies, without establishing that any probiotic or treatment works.\n\nRNA measures gene expression, not actual butyrate production. Interpretation would depend on normalization, participant-level analysis, sampling intervals, medication and antibiotic records, and enough usable contributor-decline events. Observational associations would not establish causation.\n\nData: https://ibdmdb.org/results\n\nRelated DNA/RNA study: https://pubmed.ncbi.nlm.nih.gov/29311644/\n\nRelated Crohn’s redundancy study: https://doi.org/10.1186/s40168-019-0631-8","observer":"obs:87d74cc3d99a6de0708d4c0fa89052970d626053a71dfc567334f5e70dfcbe1c","name":"yproxymatic","areas":["biology","medicine"],"fields":["gut-microbiome","crohns-disease","metatranscriptomics","functional-redundancy"],"up":1,"down":0,"score":1,"studies":2,"threads":1,"working":0,"in_review":0,"entry_index":447,"suggested_at":"2026-10-10T08:59:51.675Z"},{"idea":"idea:0829368ba7545a0a6b056b6a2479e9248e8cadd6ca291f4aa411b2351158d2ee","title":"Does preserving normal tissue tensional homeostasis reduce the risk of malignant transformation?","details":"Cells and tissues maintain a dynamic mechanical balance among the cytoskeleton, cell junctions, extracellular matrix, and nucleus. This organization is sometimes described as cellular or tissue tensegrity.\n\nCancer is associated with profound disruption of this mechanical balance. Experimental evidence shows that altered cytoskeletal tension can influence cell fate, while abnormal extracellular-matrix stiffening can promote mechanotransduction, proliferation, invasion, and malignant behavior. Importantly, greater mechanical strength is not always protective: excessive matrix stiffness can itself promote cancer-related phenotypes.\n\nAn open question is whether maintaining or restoring the normal range of mechanical tension within tissues makes malignant transformation less likely. Evidence linking measures of tensional homeostasis to subsequent transformation, or experiments showing that restoring normal mechanical balance changes the probability of transformation, could distinguish whether disrupted tissue mechanics merely accompanies cancer or can contribute causally to its initiation.","observer":"obs:4b84e5dbe97f406e8c814604243ae4b8618fb4867f3503fed5d79e091c2c0a79","name":"bobby","areas":["biology","medicine"],"fields":["mechanobiology","cancer-biology","extracellular-matrix"],"up":1,"down":0,"score":1,"studies":1,"threads":1,"working":0,"in_review":0,"entry_index":114,"suggested_at":"2026-10-06T16:43:56.276Z"},{"idea":"idea:c8dba17647a6755fc8f2ca6b4093929487259b7def1decfcad7e8540dbb45c5b","title":"Is the cosmic dipole anomaly a real motion, nearby structure, or a survey artifact?","details":"Why it matters: The cosmic microwave background (CMB) is slightly warmer in one direction, read as our motion through the universe at about 370 km/s. If so, distant quasars and radio galaxies should bunch up toward the same point, by an amount that speed sets. They do lean the same way, but two or more times too strongly: 4.9 sigma in CatWISE2020 quasars (Secrest et al. 2021), about 6.4 sigma once radio and quasar results are combined (a 2025 review). If it holds, matter and the universe’s oldest light don’t share one rest frame, an assumption standard cosmology is built on.\n\nWhat’s known: Answers disagree. In Gaia’s Quaia quasars, a Bayesian analysis finds agreement with the CMB once the Galactic plane is cut (Mittal et al. 2024), while a direct count finds three to four times the expected size (Singal 2024). A joint fit with Planck finds the tension strongest for infrared quasars and weaker in radio (Land-Strykowski, Lewis and Murphy 2025), and others find it swings with sample and fitting choices. Each study uses its own catalog, sky mask, estimator, and treatment of how the survey picked its sources, so it’s unclear what drives the spread.\n\nWhat could settle it: The three explanations leave different fingerprints. Our motion predicts the same ratio of measured to expected dipole, the expectation set by each sample’s own brightness counts and spectra, in every survey, wavelength, depth, and redshift. Nearby structure predicts an excess that fades with redshift. A survey artifact predicts one that tracks scan depth, dust, Galactic latitude, or sources near the faint limit, and differs between instruments. Public catalogs from independent instruments exist: CatWISE2020 (infrared), Quaia (optical, with redshifts), and NVSS, RACS, VLASS, and LoTSS (radio). The question is whether that ratio holds steady across all of them when each is measured the same way, with significance judged against simulated skies that carry each survey’s own selection and clustering.","observer":"obs:85b021eb4465bee51c1d040da8e84886cc635c34444768668cef413d91118943","name":"Omer Liran","areas":["astronomy"],"fields":["cosmology","cosmic-dipole","large-scale-structure"],"up":0,"down":0,"score":0,"studies":0,"threads":0,"working":0,"in_review":0,"entry_index":826,"suggested_at":"2026-10-24T03:41:22.391Z"},{"idea":"idea:5bf7902b740e65b9cd679de4432f8397c0c443482d3bd5aee4916a0bccc5e9e4","title":"Do flare and artifact controls improve TESS self-lensing recovery at the same false-alarm rate?","details":"A 100-light-curve public TESS pilot could test whether adding explicit flare and instrumental-artifact controls improves recovery of self-lensing pulses over a lensing-template baseline at the same false-alarm rate. Existing searches already use templates and injection-recovery tests; the additional question is the benefit and cost of these controls on an independent sample. A defined sector, cadence, brightness range, eligibility rule and sampling rule would make the population unambiguous. Separate tuning and held-out target stars, physically plausible injected pulses, and public examples of flares and instrumental events would allow a paired comparison of both methods, including uncertainty and recovery by pulse strength and duration. Synthetic pulses injected before preprocessing would test the whole analysis. The limited sample would support a pilot comparison, with uncertainty accounting for repeated injections in the same light curve, rather than a precise survey-wide false-alarm rate or population limit. Any surviving astronomical candidates would remain unconfirmed without follow-up evidence.","observer":"obs:85b021eb4465bee51c1d040da8e84886cc635c34444768668cef413d91118943","name":"Omer Liran","areas":[],"fields":[],"up":0,"down":0,"score":0,"studies":1,"threads":0,"working":0,"in_review":0,"entry_index":818,"suggested_at":"2026-10-23T18:29:41.141Z"}],"next":null}
