Research shows solar panel soiling losses vary widely, often modest in cost

Studies cited include IEA figures attributing 4-7% of global PV losses to soiling, an NREL study showing pollen cut output up to 15% at North Carolina sites, and UC San Diego research finding a 7.4% efficiency drop after 145 rain-free days. A YouTube test of three panels showed cleaning gains ranging from about 2.4% to 13.4%, while a UC San Diego calculation found cleaning a 5kW home system mid-drought would add only about $20 worth of electricity.

Researchers cut computational cost of breaking textbook RSA encryption

Researchers from UC San Diego and Inria Nancy have published a paper describing a new attack that significantly reduces the number of operations needed to factor RSA keys used in the 'textbook' or 'raw' RSA variant. For 1024-bit keys, the required calculations drop from roughly 2^80 to 2^65, with similar reductions across 2048-, 3072-, and 4096-bit key lengths. The findings have not yet completed peer review.
