AbstractLithium salt-doped spiro-OMeTAD is widely used as a hole-transport layer (HTL) for high-efficiency n-i-p perovskite solar cells (PSCs), but unfortunately facing awkward instability for commercialization arising from the intrinsic Li+ migration and hygroscopicity.

Editor’s summaryDeveloping good magnets often requires navigating trade-offs in various properties. This process usually involves complex alloying strategies that create magnets with undesirable properties for certain applications. Hua et al. engineered the microstructure of praseodymium cobalt magnets.

Regenerative medicine uses viable cells that are injected, grafted, or implanted into a patient to exert a desired therapeutic effect, such as healing of traumatic wounds. However, achieving efficient delivery of therapeutic cells to the target site, without loss of survival and function, and ensuring tissue integration are among the key challenges to success.

Discussions around global equity and justice in science typically emphasize the lack of diversity in the editorial boards of scientific journals, inequities in authorship, “parachute research,” dominance of the English language, or scientific awards garnered predominantly by Global North scientists. These inequities are pervasive and must be redressed. But there is a bigger problem.

More than 15 years ago, University of California San Francisco biophysicist Leor Weinberger proposed an audacious new strategy to beat the AIDS virus: giving already infected people an engineered version of HIV. The variant, stripped of nearly all its genes and designed not to cause disease, might outcompete and suppress the natural version, he thought.
