Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

open access: yesAdvanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

Spatial expansions and travelling waves of rabies in vampire bats [PDF]

open access: yes, 2016
A major obstacle to anticipating the cross-species transmission of zoonotic diseases and developing novel strategies for their control is the scarcity of data informing how these pathogens circulate within natural reservoir populations.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

open access: yesAdvanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide
