  1. Sugars are essential #biomolecules, serving as metabolic fuels, nucleic acid backbone components and structural or energy-storage polymers.

    A central question in origin-of-life research is how monosaccharides formed on the primitive Earth, as laboratory experiments under #prebiotic conditions yield insufficient concentrations.

    The detection of #ribose, #glucose and other monosaccharides in #asteroids and #meteorites suggests an exogenous origin, possibly in the interstellar medium (ISM) before meteoritic parent-body formation.

    However, no #sugar has been observed in the ISM so far.

    Now astronomers report the discovery of #erythrulose, a chiral four-carbon ketose, in the ISM.

    Erythrulose appears to be at least eight times more abundant than analogous three-carbon sugars, which remain undetected in our ultrasensitive observations.

    Quantum chemical and astrochemical models indicate that erythrulose forms efficiently on interstellar dust grains from simpler two-carbon aldehydes and alcohols.

    As ketoses readily isomerize into aldoses in aqueous conditions, interstellar erythrulose could have contributed to the sugar inventory available for early metabolic and replication processes.

  6. Most diabetes apps either track everything and overwhelm you or nothing in between.
    Glu Sight connects your daily glucose readings to an estimated A1C, so you can see the longer-term picture alongside your day-to-day numbers.

  7. Section 1. Case and Post-Mortem Analysis

    Case

    An IT professional under sustained high cognitive load and constant deadlines.

    Regimen:

    Sleep: 2–3 hours per day

    Days off: up to 4 per month

    Work sessions: long, no breaks

    Caffeine: regular use

    Symptoms:

    Episodes of loss of consciousness

    “Wobbly legs”, presyncope

    Panic attacks

    Declining memory and concentration

    Visual strain/deterioration

    ---

    Analysis (by systems)

    1. Nervous system (CNS + autonomic)

    Chronic sleep deprivation → regulatory overload.

    Disrupted sympathetic/parasympathetic balance

    Persistent “stress/survival” mode

    Adrenaline spikes without physical trigger → panic episodes

    Outcome: → panic disorder
    → cognitive deficits

    #sleepDeprivation #autonomicNervousSystem #stressResponse #panicAttacks #cognitiveDecline

    ---

    2. Cardiovascular system

    Sleep loss + stimulants → unstable heart rate and blood pressure.

    Rapid BP fluctuations

    Possible rhythm disturbances

    Outcome: → syncope
    → risk of cardiac arrhythmia

    #cardiovascular #syncope #arrhythmia #bloodPressure #heartRate

    ---

    3. Metabolic layer

    “No recovery” mode = systemic dysregulation.

    Glucose instability

    Fatigue, weakness, “wobbly” feeling

    #metabolism #fatigue #energyCrash #glucose

    ---

    4. Vision (as a trigger, not root cause)

    Continuous focal strain

    Dry eye syndrome

    Outcome: → Computer Vision Syndrome

    #vision #digitalEyeStrain #screenTime #eyeFatigue

    ---

    Causal chain

    Sleep deprivation (core)

    Autonomic dysregulation

    Stress/panic + BP instability

    Presyncope

    Loss of consciousness

    #rootCause #systemFailure #causeEffect

    ---

    Misinterpretation

    Hypothesis: “It’s caused by vision.”
    Fact: vision increases load on an already failing system; it’s not the root.

    #diagnostics #misattribution #rootCauseAnalysis

    ---

    Critical risks (if unchanged)

    More frequent syncope

    Consolidation of anxiety disorder

    Persistent cognitive decline

    Increased cardiac risk

    #riskAssessment #healthFailure #burnout

    ---

    Conclusion

    This is not a local issue (eyes/stress). It’s a systemic decompensation driven by chronic sleep deprivation.
    Symptoms are no longer early-stage; they are borderline.

  9. is a monitoring application written in . It fetches interstitial sugar readings from continuous glucose monitors (CGM) via different APIs and shows them on the desktop. It also presents a trend over time, colouring, and JavaScript extensions.
