How to Run Apple Diagnostics on Your Mac to Check Hardware Health

Apple’s hidden Diagnostics tool can test hardware on both Apple Silicon and Intel Macs. To use it, update macOS, disconnect nonessential peripherals, then boot into Diagnostics: Apple Silicon users hold the power button until Options appears and then press Command + D; Intel Macs press D (or Option + D). Run the desired checks, and note the reference code (ADP000 means no issues). Apple provides many diagnostic checks and repair options, including self-service repair, if issues are found.

Saliva Clues to Colorectal Cancer Surface in Microbiome Study

A study of 507 individuals analyzed saliva and stool to create a mouth-to-feces (MF) index, finding higher MF in gastrointestinal cancer patients and showing oral samples could better detect colorectal cancer than some standard tests, suggesting a noninvasive screening route that still requires more research before clinical use.

Microsoft denies a new Windows 11 tracker, calling it a diagnostic feature

Microsoft says the so‑called Windows Health and Optimized Experiences is not a new tracking service in Windows 11. It’s described as a diagnostic feature that runs when the OS detects a slowdown, stores logs locally, and only sends data back to Microsoft if the user submits a Feedback Hub report. The feature isn’t new (present since a May 2025 Windows 11 Canary build) and is not standalone telemetry; Microsoft emphasizes better performance with no new AI or telemetry services.

Microsoft debunks Windows 11 tracking myth, explains whesvc's real role

A viral post alleging Windows 11 secretly spies on desktops is debunked. The Windows Health and Optimized Experiences service (whesvc) is a diagnostics component that powers Adaptive Energy Saver and local performance tracing, not a covert data-leak tool. Traces stay on-device unless you submit Feedback Hub, and the feature is not laptop-only. It can be disabled via Services.msc or terminal commands. Microsoft’s Scott Hanselman clarified the details to counter the rumor.

Toyota's Hidden Diagnostics Screen Revealed in Infotainment

A TikTok reveals that newer Toyota models hide a diagnostic screen inside the infotainment system. Access requires turning the radio off, enabling the display, and swiping edge-to-edge five times in one direction and five in the opposite until the hidden diagnostic menu appears, which can check mic, touchscreen, backup camera, sensors, and production info. The feature is finicky and should only be used by certified Toyota technicians, since changing settings without expertise can cause issues.

Six Samsung Galaxy Dial Codes That Unlock Hidden Phone Tools

The Android Authority piece highlights six Samsung Galaxy MMI dial codes that reveal hidden phone tools: *#06# for IMEI (two IMEIs on dual‑SIM), *67 or *31# to hide caller ID, *#0808# to view and set USB connection modes, *#2663# to access a touchscreen firmware and Wi‑Fi refresh menu, *#9900# to delete old system logs, and *#0*# to run a hardware diagnostics suite for speakers, touch, sensors, and more. It also notes you must disable One UI Auto Blocker for many codes to work (it re-enables after 30 minutes on newer versions) and that carrier-locked devices may see “connection problem” errors due to carrier restrictions.

NHS to speed up endometriosis diagnosis with two rapid tests

NICE approves two non-invasive tests—Endotest and EndoSure—for rapid endometriosis diagnosis on the NHS in England and Wales, with a three-year draft approval to gather more evidence. Endotest uses a saliva test for microRNAs; EndoSure measures gut electrical activity to produce results in about 45 minutes. A third test, DotEndo, needs more research. Intended for patients where suspicion remains after normal exams or inconclusive imaging, these tests aim to cut the typical multi-year diagnostic delay and speed access to treatment.

Period Blood Emerges as a Promising Medical Resource

New studies show menstrual fluid speeds skin wound healing, may enable noninvasive cervical cancer screening with high sensitivity, can help detect endometriosis with a simple test strip, and contains stem cells with regenerative potential for infertility and neurological conditions, suggesting period blood could become a valuable biomedical resource rather than waste.

Handheld cancer detector nears home-based early-detection breakthrough

Researchers at Westlake University in China have unveiled a handheld cancer-screening device that can detect early-stage cancer biomarkers from a single blood drop. Using a compact 3D metamaterial Bound States-in-the-Continuum sensing chip, the device replaces bulky laboratory equipment with a portable chip, LED, and photodetector, enabling at-home or remote testing. In trials with 171 patient serum samples, it achieved 94.9% accuracy for early cancer detection and 92.1% for post-surgery monitoring—far outperforming the standard ELISA method (74.7%). The team also claims mass production of thousands of identical chips per wafer at about $5 per chip. Findings were published in Nature Photonics and demonstrated 10,000x greater sensitivity than ELISA in spotting lung-cancer biomarkers.

Nebraska Lab Puts Early Andes Virus Test to Work for Cruise-Ship Passengers

Researchers at the University of Nebraska Medical Center rapidly developed a PCR-based test to detect Andes virus in blood before symptoms appear and plan to screen 16 returning cruise-ship passengers, aiming for early diagnosis and treatment to curb spread—though the CDC’s Andes virus PCR test is still being validated for patient management.

Cruise-ship hantavirus outbreak exposes gaps in early diagnosis and prevention

In a Washington Post opinion, Abraar Karan argues that the Hondius hantavirus outbreak—and a prior Argentina incident—expose how slow recognition and limited on-site testing hinder outbreak control. Hantavirus can spread between people and cause severe heart-lung illness, with symptoms that are often non-specific and appear weeks after exposure, making early diagnosis challenging. The piece advocates more proactive travel-health screening, broader and faster diagnostics (like metagenomic sequencing and PCR panels), and greater investment in point-of-care tests to curb shipboard and cross-border transmission, while noting cost and biosafety barriers remain substantial.

WHO backs near-point-of-care TB tests and tongue swabs to speed diagnosis

WHO endorses portable, near-point-of-care TB tests that are battery-powered and deliver results in under an hour, plus tongue-swab sampling and sputum pooling to expand testing, cut costs, and start treatment sooner; the guidance, released for World TB Day 2026, calls for urgent scale-up and sustained investment as funding gaps threaten progress, with potential benefits for testing other diseases as well.

Abbott to close Exact Sciences acquisition, expanding cancer diagnostics leadership

Abbott expects to close its acquisition of Exact Sciences on March 23, 2026 after regulatory clearances, adding Exact’s cancer-screening and precision-oncology portfolio (Cologuard, Oncotype DX, Oncodetect, Cancerguard) to expand Abbott’s diagnostics leadership. The deal is projected to bring about $3 billion of incremental sales in 2026, accelerate Abbott’s growth in diagnostics, and dilute 2026 adjusted EPS by about $0.20, as the company aims to make cancer detection and management more accessible.

Grail's Galleri multi-cancer test misses primary endpoint in NHS study, fueling skepticism

Grail's Galleri blood test for early cancer detection failed to meet its primary endpoint in a large NHS-backed study, renewing questions about its clinical utility despite some detected benefits. Grail reported selling 185,000 tests in 2025 for $136.8 million, and its stock fell about 47% after hours following the setback.
