Advanced Materials Top 40 for May 9, 2012

Immune resilience gene signature could hold the key to healthy aging

High levels of a certain biomarker gives people a survival advantage, study finds.

Kirigama-inspired neural probes are a cut above

The flexible and foldable 3D probes were surprisingly durable when inserted into brain tissue to map the deep functioning of neurons.

Working close to robots could be safer with cutting-edge Kirigami e-skin

The sensitive e-skin robotic coating applies ultrasonics and AI while taking its inspiration from the Japanese art of Kirigami.

Water-powered gadgets may be on the horizon thanks to new evaporation-based energy device

Scientists created an “evapolectrics” generator that draws power directly from water evaporation, offering a sustainable, battery-free energy source from humidity.

New theory suggests gravity is not a fundamental force

A new theory proposes gravity isn’t a fundamental force but emerges from quantum electromagnetic interactions, potentially reshaping our view of spacetime itself.

Climate pledges could shrink global cropland

The tradeoff raises concerns about food security, particularly for the Global South.
