FDA flags false-positive cyclosporiasis result, reshaping outbreak link to iceberg lettuce

Delaware reports its first cyclosporiasis case this year as part of a multistate outbreak still under investigation; nationwide cases exceed 1,600 with 94 hospitalizations, though many infections go unreported. The FDA has concluded a recent cyclospora lab signal was a false positive, removing the previously suspected link to iceberg lettuce tied to Taco Bell. The Taylor Farms de Mexico iceberg lettuce recall remains in effect and Walmart-distributed products are among those affected; the public is advised to discard recalled lettuce and clean affected surfaces while investigators continue to determine the true source.

False HIV Result Highlights Gaps in Georgia Urgent-Care Communication

In DeKalb County, Georgia, a teen’s HIV-positive result from Pickens Urgent Care was later determined to be a false positive, and the clinic never notified the family, who learned of the result from the teen’s MyChart portal. The ordeal led to a near suicide attempt and months of distress before multiple other facilities’ tests all came back negative. The CDC recommends direct, confidential communication of positive HIV results and immediate linkage to follow-up care, counseling and support. Investigations also found inconsistent follow-up scheduling at the clinic, and there is no state-level regulatory body specifically overseeing urgent-care centers in Georgia; the clinic finally reached out after Channel 2 Action News inquiries. The mother hopes the case prompts stronger safeguards to prevent similar harm to other teens.

Microsoft Defender Misclassifies DigiCert Root Certificates as Malware

Microsoft Defender’s late-April 2026 signature update wrongly flagged two DigiCert root certificates as malware (Trojan:Win32/Cerdigent.A!dha), quarantining their entries in Windows’ AuthRoot/Certificates store and risking SSL/TLS validation and code-signing for enterprise software. A corrective definition update (.430) began restoring the certificates, with automatic remediation rolling out and admins advised to verify restoration via certutil and Advanced Hunting logs. This incident underscores the risks of false positives in automated security responses targeting core Windows components.

The Elusive Existence of Alien Moons and Gas Moons in Space

Recent research suggests that the previously detected hints of alien moons in the Milky Way may not actually exist. The evidence for two distant moons orbiting exoplanets outside the Solar System is now believed to fit better with other explanations. However, the techniques used to rule out the presence of these moons can be used in future observations to find exomoons. While finding exomoons is challenging due to their small size and proximity to their host exoplanets, the discovery of even one exomoon would be significant and provide exciting opportunities for exploration.

Breakthrough Blood Test Detects Cancer with 99% Accuracy

The Galleri liquid biopsy, a blood test that can screen for over 50 types of cancers, has gained popularity among affluent and health-conscious individuals seeking early cancer detection. However, while some doctors and patients believe in its potential benefits, others caution against its use due to the lack of evidence showing it can prevent cancer deaths and the risk of false positive or negative results. The test's proponents argue that catching cancer earlier outweighs these concerns, but critics emphasize the need for further research and FDA approval. The test is not recommended for pregnant individuals, those under 21, or those undergoing active cancer treatment.

3CX Desktop App Compromised in Supply Chain Attack.

VoIP/PBX software provider 3CX was aware that its desktop app was being flagged as malware but decided to take no action for a week when it learned it was on the receiving end of a massive supply chain attack. Users soon decided the detection was a false positive triggered by a glitch in the SentinelOne product. However, it would be another 24 hours before the world learned that SentinelOne was right and the people suspecting a false positive were wrong. The breakdown involving the disregarded detection by 3CX and its users should serve as a cautionary tale to both support teams and end users.
