Dark-matter hunt widens as Kenyan entrepreneurs push solar milling

The search for dark matter has been blown wide open. For decades physicists hunted weakly interacting massive particles, but their efforts now run into a “neutrino fog” from the sun and other stars that can drown out dark-matter signals; researchers are shifting tactics with proposals that range from quantum sensors and liquid-helium detectors to even searches in Jupiter’s atmosphere.

In Nairobi, entrepreneurs are making the case for going solar. Milcah Wanjiru’s grain mill runs on either solar energy or the grid, and with about a quarter of Kenya’s population lacking centralized electricity, off-grid solar is being promoted as a route to universal access by 2030; it can cut operating costs and improve profits once the upfront investment is recovered.

Solar geoengineering still faces major practical challenges.
