“She loves me, she loves me not”: physical forces encouraged evolution of multicellular life, scientists propose

Marine Biological Laboratory
Peer-Reviewed Publication

A study appearing Monday, March 31 in Nature Physics presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. Based on the fluid dynamics of cooperative feeding by Stentor, a relatively giant unicellular organism, the study originated from the Marine Biological Laboratory (MBL), Woods Hole, Mass.

Joint consensus highlights the role of bone turnover markers in osteoporosis diagnosis and management

International Osteoporosis Foundation
Peer-Reviewed Publication

A new consensus paper, published by the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO), the International Osteoporosis Foundation (IOF), and the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC), provides an updated evaluation of reference bone turnover markers (BTMs) and newer markers in the diagnosis and management of osteoporosis. The paper reassesses the clinical utility of BTMs in predicting fracture risk and monitoring osteoporosis treatment based on evidence from the past decade. The study reaffirms the use of procollagen type I N propeptide (PINP) and β-isomerized C-terminal telopeptide of type I collagen (β-CTX-I) as reference BTMs, with standardized measurement protocols for clinical studies and patient monitoring.

Stereoisomeric engineering for critical balance of solvation and adsorption capability

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

This study introduces the stereoisomerism to inform the balanced selection of electrolyte additives to achieve the optimal deposition behaviors and electrochemical performance. An appropriate level of solvation ability and adsorption ability can facilitate faster deposition kinetics and encourage the preferential orientation growth of (002) planes. With sorbitol, the symmetrical battery can stably cycle for over 3470 h at 2 mA cm^-2 and 1 mAh cm^-2, and full battery also exhibits excellent electrochemical performance.
