- 1Study finds sodium bicarbonate and carbs boost athletic performance▼Nutrition study highlights performance benefit of sodium bicarbonate and carbohydrate co-ingestion
A nutrition study reported by World Athletics indicates that taking sodium bicarbonate together with carbohydrate improves endurance performance more than either supplement alone. The co-ingestion approach appears to help athletes sustain higher outputs while reducing gastrointestinal problems often linked to bicarbonate use. The findings are being shared among coaches and endurance athletes looking for legal performance gains.

In Mount Elgon's Kitum Cave in Kenya, African savannah elephants use their tusks to scrape volcanic rock for sodium, calcium and magnesium. Generations of herds have hollowed out these deep mineral chambers, passing the unusual mining behaviour down through the herd. The story is being shared as a striking example of animal culture and adaptation.
- 3German startup wins grant for sodium-ion home battery▼German startup wins grant for grid-charging sodium-ion home battery
A German startup has been awarded a grant to develop a sodium-ion home battery that charges from the electricity grid. The funding supports the company's work on an alternative to lithium-ion residential storage, a technology attracting attention for its cheaper materials and reduced reliance on critical minerals. The award was reported by energy storage trade press, though details on the company, grant amount and timeline have not been disclosed.
- 4Confusion spreads over low-sodium salt labelling●Ok so table salt. That’s sodium chloride. Sodium and chlorine. So this is less sodium. So… more chlorine?? # salt # salt
People are puzzling over reduced-sodium table salt, joking that if salt is sodium chloride, cutting the sodium must mean more chlorine. The posts highlight a common misunderstanding: low-sodium salts typically replace sodium chloride with potassium chloride, an additive that tastes salty but carries health risks for some people, including those with kidney problems or on certain blood pressure medications.
- 5Powering Devices With Sodium: Risky DIY Battery Idea●Power It With Sodium (But Please Don't) https://hackaday.com/2026/10/01/power-it-with-sodium-but-please-dont/ # Science
Hackaday has published a piece exploring sodium as a power source for electronics, urging readers not to actually try it. The article walks through the chemistry and practical hazards of sodium-based power, framing it as an interesting experiment that is unsafe to replicate at home. The piece is being shared among DIY and battery technology enthusiasts.

Former CDC director Tom Frieden argues people should switch to salt substitutes rather than pass the salt, highlighting potassium-based alternatives as a way to cut sodium intake and reduce high blood pressure and heart disease. The message urges households and food producers to make the swap for better health.
