- Crack deflection in laminates with graded stiffness—lessons from biology 17. March 2023A crack propagating through a laminate can cause severe structural failure, which may be avoided by deflecting or arresting the crack before it deepens. Inspired by the biology of the scorpion exoskeleton, this study shows how crack deflection can be achieved by gradually varying the stiffness and thickness of the laminate layers. A new generalized […]Israel Greenfeld and H Daniel Wagner
- A bar-joint model based on the corrected resistive force theory for artificial flagellated micro-swimmers propelled by acoustic waves 13. March 2023In this work, we proposed a bar-joint model based on the corrected resistive force theory (CRFT) for studying artificial flagellated micro-swimmers (AFMSs) propelled by acoustic waves in a two-dimensional (2D) flow field or with a rectangular cross-section. Note that the classical resistive-force theory for 3D cylindrical flagellum leads to over 90% deviation in terminal velocity […]Jinan Liu, Yiqiang Fu, Xiongjun Liu and Haihui Ruan
- Effect of valve spacing on peristaltic pumping 9. March 2023Peristaltic fluid pumping due to a periodically propagating contraction wave in a vessel fitted with one-way elastic valves is investigated numerically. It is concluded that the valve spacing within the vessel relative to the contraction wavelength plays a critical role in providing efficient pumping. When the valve spacing does not match the wavelength, the valves […]Ki Tae Wolf, Amir Poorghani, J Brandon Dixon and Alexander Alexeev

- Decrypting drug actions and protein modifications by dose- and time-resolved proteomics | Science 16. March 2023Although most cancer drugs modulate the activities of cellular pathways by changing post-translational modifications (PTMs), surprisingly little is known regarding the extent and the time- and dose-response characteristics of drug-regulated PTMs. Here, we ...
- Beyond protected areas for koala conservation | Science 16. March 2023Australia recently declared the koala (Phascolarctos cinereus) an endangered species in Queensland, the Australian Capital Territory, and New South Wales (NSW) because of its stark population decline (1, 2). In the state of NSW, koala conservation has become a key topic of discussion in the lead-up to the 25 March state election (3). However, the […]
- Surface changes observed on a Venusian volcano during the Magellan mission | Science 15. March 2023Venus has a geologically young surface, but it is unknown whether it has ongoing active volcanism. From 1990 to 1992, the Magellan spacecraft imaged the planet’s surface using synthetic aperture radar. We examine volcanic areas on Venus that were imaged ...

- Inheritance of epigenetic DNA marks studied in new mouse model 21. March 2023Nature, Published online: 21 March 2023; doi:10.1038/d41586-023-00708-8There is debate about how epigenetic marks, such as methyl groups on DNA, can be passed down from parent to offspring. A mouse model involving targeted DNA methylation will better equip researchers to study this process.Serge McGraw
