Interdisciplinary strategies bridging oncology, neuroscience, bioelectronics and materials science will facilitate the development of next-generation therapies and devices for cancers of the central nervous system.

The increasing popularity of electric vehicles as an alternative to internal combustion engine vehicles brings new realities, challenges and opportunities for scientists and engineers. A key element of this transition will be to develop solutions for lubrication, thermal management, electrical compatibility and corrosion inhibition. Two-dimensional materials are well poised to address these challenges and enhance the performance, efficiency, durability and, hence, sustainability of electric vehicles during this century and beyond.

Light-emitting perovskite solar cells are emerging optoelectronic devices that integrate light-emitting and electricity-generating functions in one device. This type of device unlocks new possibilities for applications as outdoor light sources, in multifunctional architecture, smart automobiles, self-powered displays and portable power floodlights.

An article in Nature describes regular, modular protein building blocks that can be combined — following a standard blueprint — into a variety of architectures.

An article in Advanced Materials presents a drug delivery platform for cancer chemotherapy that is activated by radiation.

An article in Nature Materials reports the use of a co-doping strategy to produce a Cu₂Se-based superionic material that has a figure of merit of 3 at 1,050 K, an efficiency of over 13% when integrated into a thermoelectric module and good operational stability.

India’s commitment to its ambitious technology goals brings a unique opportunity for the materials science community in the country to achieve synergy, focus, large-scale employment and global impact. However, scientists need to engage more spontaneously in goal-oriented collaborations along with stakeholders in industry and government.

As new materials and manufacturing techniques are discovered, their benefits transform every branch of science and engineering. In spacecraft propulsion, a new generation of ion engines could provide unprecedented performance and flexibility in space mission design.

Nanoparticles (NPs) administered in the human body will undergo rapid surface modification upon contact with biological fluids driven by their interfacial interaction with a diverse range of biomolecules. Such spontaneous self-assembly and adsorption of proteins and other biomolecules onto the NP surface constitute what is commonly known as the protein or biomolecule corona. This surface biotransformation of the NPs modulates their biological interactions and impact on physiological systems and can influence their overall pharmacological profile. Here, we comment on how the initially considered ‘nuisance’ of the in vivo corona formation can now be considered a nanoparticle engineering tool for biomedical use, such as in endogenous tissue targeting, personalized biomarker discovery and immunomodulation.

An article in Science Advances presents a method to create starch superstructures to potentially improve food supply.

An article in Matter uses rice grains as scaffolds for cultivated beef cells to produce an innovative beef-infused rice.

Solar photovoltaics has tremendous potential to address current gaps in electricity access for resource-challenged settings, such as sub-Saharan Africa. However, a rapid surge in installations and future growth will lead to an increase in waste from panels and batteries, which needs to be tackled urgently. Innovative technical solutions and improved policies and standards are required to address end-of-life challenges for solar photovoltaics in sub-Saharan Africa.

Material World: A Substantial Story of Our Past and Future, the latest book by Ed Conway, explores the materials that underline our modern civilization, discussing their supply and manufacturing, but also history and innovators.

Materialism, a podcast exploring the past, present and future of materials science, is turning five. Co-founders and co-hosts Taylor Sparks (a professor at the University of Utah) and Andrew Falkowski (a PhD student in Sparks’ group) discuss how they use storytelling to create compelling episodes and share their journey and lessons learned.

An article in Nature Machine Intelligence presents an adaptable method to control magnetic microrobots’ navigation using reinforcement learning.

Minimally invasive surgery (MIS) lacks sufficient haptic feedback to the surgeon due to the length and flexibility of surgical tools. This haptic disconnect is exacerbated in robotic-MIS, which utilizes tele-operation to control surgical tools. Tactile sensation in MIS and robotic-MIS can be restored in a safe and conformable manner through soft sensors and soft haptic feedback devices.
