Thanks to South Africa’s world-class capacity to detect & track viruses & infections, developed largely through the our response to HIV, we’re once again in the spotlight for identifying & managing a small outbreak. Few countries are as transparent about this type of thing.

Do you guys think you’ll still be tweeting when you’re 40?



Yesterday in London, two men ran under the two-hour marathon. Sawe in 1:59:30, Kejelcha in 1:59:41. A barrier that has stood for decades, gone. None of their watch data is on Terra. But 571 other runners on the same streets are, and their data turned up something I wasn't expecting. The spread of the field alone is fascinating. Finish times ranged from sub-2:12 to nearly 7 hours. Heart rates told a counterintuitive story too: sub-3 runners averaged 167 bpm for the entire race, while six-hour finishers averaged 154. But the calorie data is what really jumped out. Garmin and Coros watches agreed on heart rate. They agreed on distance. They disagreed on calories by 12% at the median, and the gap got much worse for slower runners. Here's the part that I think matters: kcal/km should be roughly flat across finish-time bands on the same course on the same day. The fact that one device produces a flat line and the other produces a steep one is a self-contained plausibility check on the calorie algorithm. Calories from a watch are a model output, not a measurement, and the slower you run, the further the model can drift from physiology. This is exactly the kind of question we're tackling at the Terra Research Run Club this Thursday, built to advance our understanding of wearable data in the real world, and ask how well our watches actually capture what's happening.

[DRUG TRAFFICKER ARRESTED WITH 60KG OF KHAT] It has been a busy long weekend for Police at OR Tambo International Airport(ORTIA), with significant breakthroughs in the figh against drug trafficking. In the latest drug bust, police intercepted a Netherlands national with 60kg of KHAT concealed in his luggage. The drug trafficker was set to take-off to London on Sunday morning when he was intercepted at the Airport. His luggage was inspected and 60kg of khat was found concealed inside. This is less than 24 hours after the arrest of a Brazilian national found with cocaine worth an estimated R8.7 million at the same airport. The latest arrests demonstrates the vigilance and heightened operations by SAPS working closely with ACSA security, BMA officials, SARS customs at ports of entry. The back to back successes in intercepting drug traffickers underscores the country's firm stance against transnational organised crime and law enforcements commitment to safeguarding South Africa’s borders. The drug mule is expected to appear before the Kempton Park Magistrate's Court this week on charges relating to drug trafficking.
