Why does Singapore’s PSI readings differ from the air quality index found on other websites? NEA explains: https://str.sg/7yYH Experts also said that the country’s central region registers the worst air quality due to high urbanisation.   Here's the full detailed account:       🌫️ Central Singapore: Worst Air Quality — Why?   📊 The Situation (Sep 2026)   - Haze since Sep 4; central region consistently highest PSI across all 5 zones  - Sep 15, 6am: Central hit 154 (unhealthy); others 104–128 — first time since 2019 all regions unhealthy  - 11:30pm Sep 15: Central 115; West 101; East 95; North 86; South 82  - Central covers: Thomson, Marymount, Sin Ming, Ang Mo Kio, Bishan, Serangoon Gardens, MacRitchie, Toa Payoh    🧑‍🔬 Expert Explanations   Urban heat & turbulence — NUS Adj. Assoc. Prof. Koh Tieh Yong:   - Central = most built-up & urbanised → concrete retains heat → stronger updrafts & air turbulence  - Incoming PM2.5 from Indonesia fires gets trapped & concentrated closer to ground by this turbulent air  - When haze is thick enough, entire island becomes unhealthy (as seen Sep 15)    Dry conditions + local emissions — NTU Prof. Steve Yim:   - Dry weather allows haze particles from Indonesia to mix with downtown/local emissions, amplifying central readings        ⚖️ PSI vs Other AQI — NEA's Clarification   Key Differences    Singapore 24-hr PSI Other AQI (e.g. aqicn.org, IQAir)  Calculation Based on 24-hour averages for all 6 pollutants[__LINK_ICON] Uses shorter averaging periods (1-hr) & different formulas  Pollutants PM2.5, PM10, SO₂, NO₂, O₃, CO — all measured by highly specialised, certified equipment[__LINK_ICON] May use NEA data + low-cost, less consistent sensors from private contributors[__LINK_ICON]  Result Generally lower/milder readings than AQI Often higher/poorer air quality displayed  Status Official national standard — tailored to Singapore's haze context[__LINK_ICON] Independent systems — not directly comparable[__LINK_ICON]    NEA's Statement   - "No international guidelines on computation; each country designs to local needs"  - PSI not identical to US EPA AQI despite referencing it  - Comparisons will show inconsistent results — trust NEA's 24-hr PSI as official        ⚠️ Health Guidance (PSI > 100 = Unhealthy)   - Healthy people: reduce prolonged/outdoor strenuous activity  - Those with heart/lung conditions: avoid such activity    Source: The Straits Times, Sep 15 2026 — https://str.sg/7yYH   Singapore 24-hr PSI Other AQI (e.g. aqicn.org, IQAir) Calculation Based on 24-hour averages for all 6 pollutants[__LINK_ICON] Uses shorter averaging periods (1-hr) & different formulas Pollutants PM2.5, PM10, SO₂, NO₂, O₃, CO — all measured by highly specialised, certified equipment[__LINK_ICON] May use NEA data + low-cost, less consistent sensors from private contributors[__LINK_ICON] Result Generally lower/milder readings than AQI Often higher/poorer air quality displayed Status Official national standard — tailored to Singapore's haze context[__LINK_ICON] Independent systems — not directly comparable[__LINK_I CON]

The payroll system of mosques and madrasahs overseen by MUIS has been hacked and held for ransom.   Sensitive information of staff, including their names, contact details, salaries and bank account numbers, is potentially compromised.   https://str.sg/fYFp   Here’s the full detailed account of the incident:       🕐 Timeline   - Aug 30–31, 2026: Ransomware activity detected on SmartHRMS, the cloud-based HR & payroll system operated by Singapore vendor Avelogic  - Aug 31: Avelogic filed police report - Sep 7: First notice issued — databases including backups encrypted, no clean recovery point; unexplained outbound transfers meant data theft could not be ruled out  - Sep 14: Updated notice — forensic review found no evidence of bulk data theft; recovered latest dataset; target restoration by Sep 18  - Sep 15: Story published in The Straits Times; MUIS confirmed breach    🏛️ Parties Involved   - MUIS: Islamic Religious Council of Singapore; oversees 72 mosques — payroll covers 69 mosques + 3 madrasahs via Mosque-Madrasah-Wakaf Shared Services  - Avelogic: System provider; reported to Police & PDPC; retained cybersecurity firm Black Panda for investigation - Authorities: Singapore Police Force + Personal Data Protection Commission (PDPC) — both investigating    🔓 What Was Compromised   - System held staff data: names, contact info, salaries, bank account numbers  - Core sensitive fields protected by application-layer encryption - Initially: encryption of all databases & backups → no system access; payroll processed manually  - Later update: no bulk data exfiltration confirmed    ⚠️ Impact & Status   - No disruption to public/government services  - Manual payroll processes in place; staff being guided & supported  - MUIS has not confirmed ransom paid, number of affected employees, or exact data accessed — citing ongoing investigations  - Avelogic rebuilding in new secure environment; service resumption targeted Sep 18, 2026        Source: The Straits Times, Sep 15 2026 — https://str.sg/fYFp
