Long legs and small joints: The locomotor capabilities of Homo naledi.
J Anat
January 2025
Evolutionary Studies Institute, University of the Witwatersrand, Johannesburg, South Africa.
The lower limb of Homo naledi presents a suite of primitive, derived and unique morphological features that pose interesting questions about the nature of bipedal movement in this species. The exceptional representation of all skeletal elements in H. naledi makes it an excellent candidate for biomechanical analysis of gait dynamics using modern kinematic software.

Peri-mesencephalic subarachnoid haemorrhage (PMSAH) is considered to be a clinically benign subset of subarachnoid haemorrhage (SAH). Cranial nerve palsies have been previously reported as rare sequelae of PMSAH. Herein, we report an unusual case of multiple cranial nerve palsies as a presenting feature of PMSAH and a review of the literature for cranial nerve palsies post-PMSAH.

Keratoconus is a progressive corneal ectasia that may lead to severe visual impairment. Superior keratoconus (SK) is an uncommon form of the disease, and few cases have been reported thus far. We present an unusual SK case and a literature review of this rare diagnosis.

School of Traditional Chinese Materia Medica, Shenyang Pharmaceutical University, Shenyang 110016, People's Republic of China.
Three seco-norabietane diterpenoids, salvicsites A-C (-), along with two known compounds, were isolated from the roots and rhizomes of Diels f. Stib. Salvicsite A () represents an unprecedented structural combination, featuring an eight-membered α-methyl-α,β-unsaturated lactone ring and a five-membered α,β-unsaturated lactone ring, based on a 6/6/5/8 ring system.

Nat Commun

Faculty of Materials Science and Chemistry, China University of Geosciences, Wuhan, China.
Inspired by counterintuitive water "swelling" ability of the hydrophobic moss of the genus Sphagnum (Peat moss), we prepared a hydrophobic pseudo-hydrogel (HPH), composed of a pure hydrophobic silicone elastomer with a tailored porous structure. In contrast to conventional hydrogels, HPH achieves absorption-induced volume expansion through surface tension induced elastocapillarity, presenting an unexpected absorption-induced volume expansion capability in hydrophobic matrices. We adopt a theoretical framework elucidating the interplay of surface tension induced elastocapillarity, providing insights into the absorption-induced volume expansion behavior.
