Semiconductors are a crucial component of devices such as smartphones, computers, LEDs, and solar cells. New generation solar cells which use perovskite and organic semiconductors  are gaining attention for applications in flexible electronics, light-emitting devices, and high-efficiency solar cells. This technology becomes crucial for helping reduce reliance on fossil fuels.

A major challenge in bettering existing semiconductor technology is the process of electronic doping. Conventional doping techniques often rely on metal salts, chemical additives, and slow processing methods that can leave residues, reduce long-term stability, and depend heavily on trial-and-error optimization.

Pabitra Nayak and colleagues have developed a new approach called in situ regenerative adduct-assisted (IRAA) doping, demonstrated in halide perovskite solar cells, which makes the process of doping cleaner, faster, and more efficient.

Flaky tests—automated checks that produce inconsistent results—are a persistent issue in software development, wasting time and computational resources. Researchers from Kyushu University analyzed 649 projects in the OpenStack ecosystem and found that over half were affected by flakiness that often spreads across projects. They identified cross-project flakiness caused by an unstable test affecting multiple projects and inconsistent flakiness as key phenomena.

Scuba-diving tourism, which is widely promoted as a sustainable way to experience coral reefs, is causing frequent and often hidden damage to fragile marine ecosystems.
