Plus: The Pentagon says it used Grok in strikes on Iran.
This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.
For decades, physicists have hunted for weakly interacting massive particles (WIMPs), a leading candidate for dark matter. But their search has run into a new problem: neutrinos.
These tiny particles from the sun and other stars can create a “neutrino fog” that drowns out any signal of dark matter. Hitting the neutrino fog does not, however, mean an end to the search. Researchers just have to shift the focus of their hunt.
They’re now casting a much wider net. New proposals include quantum sensors, liquid-helium detectors, and even searches in Jupiter’s atmosphere.
Find out how the search for dark matter has entered entirely new territory.

Shops with diesel-powered grain mills are common in Nairobi. Milcah Wanjiru’s is different: it runs on either solar energy or the grid.
About a quarter of Kenya’s population still lacks centralized electricity, and off-grid solar is being promoted as a route to universal access by 2030. In Wanjiru’s case, it cuts operating costs and can improve profits once the upfront investment is recovered.
Read the full story on the rise of solar milling systems across Kenya and beyond.
Solar geoengineering is often portrayed as a sort of emergency brake. Something along the lines of "Pull in case of climate emergency to scatter light-reflecting particles to bounce sunlight out of the atmosphere and cool the planet."
But it might be less like a simple brake the more like a complicated, entirely unsolved puzzle. My colleague James Temple dug into these engineering challenges in his latest feature story. My biggest takeaway? This all looks a lot harder than I thought.
Read the full piece to find out why.

Women remain grossly underrepresented in the technology industry. At the core of the problem is money: tech has generated enormous personal fortunes, and most of that wealth has gone to men.
White and Asian men manage 93% of venture dollars. In 2021, only 2% of venture capital funding went to startups founded solely by women.
The lack of investor and founder diversity doesn’t only determine who gets rich. It also shapes the kinds of problems technology companies set out to solve.
