Experimental increases in temperature mean and variance alter reproductive behaviours in the dung beetle .

Temperature profoundly impacts insect development, but plasticity of reproductive behaviours may mediate the impacts of temperature change on earlier life stages. Few studies have examined the potential for adult behavioural plasticity to buffer offspring from the warmer, more variable temperatures associated with climate change. We used a field manipulation to examine whether the dung beetle alters breeding behaviours in response to temperature changes and whether behavioural shifts protect offspring from temperature changes.

Cluster Fragments in Amorphous Phosphorus and their Evolution under Pressure.

Amorphous phosphorus (a-P) has long attracted interest because of its complex atomic structure, and more recently as an anode material for batteries. However, accurately describing and understanding a-P at the atomistic level remains a challenge. Here, it is shown that large-scale molecular-dynamics simulations, enabled by a machine-learning (ML)-based interatomic potential for phosphorus, can give new insights into the atomic structure of a-P and how this structure changes under pressure.

Thumb-Basal Joint Arthroplasty Outcomes and Metacarpal Subsidence: A Prospective Cohort Analysis of Trapeziectomy With Suture Button Suspensionplasty Versus Ligament Reconstruction With Tendon Interposition.

Background: Thumb carpometacarpal (CMC) joint arthroplasty is a common procedure in the surgical management of symptomatic thumb basal joint arthritis. Following trapeziectomy, a number of suspensionplasty techniques are often used, but limited comparative evidence exists between these techniques. The central aim of this study was to prospectively compare the outcomes of 2 suspensionplasty techniques following trapeziectomy: suture button (TightRope) versus ligament reconstruction and tendon interposition (LRTI).

Predictive Factors for Return to Driving following Volar Plate Fixation of Distal Radius Fracture.

 A common query by patients undergoing distal radius fracture (DRF) repair is when (s)he can resume driving postoperatively. A prospective cohort analysis was performed to assess fracture and patient factors on a patient's self-reported ability to return to driving to better inform patients and surgeons.  Consecutive patients undergoing DRF repair with locking volar plate were enrolled.

Radiographic Incidence and Functional Outcomes of Distal Radius Fractures Undergoing Volar Plate Fixation With Concomitant Scapholunate Widening: A Prospective Analysis.

Scapholunate (SL) ligament injuries can occur concomitantly with distal radius fractures (DRFs), and the management of acute SL injury in the setting of DRFs remains controversial. The purpose of the study is to identify the radiographic incidence of SL widening in DRF treated with volar plate fixation and to determine the functional outcomes of DRF with concomitant radiographic SL-widening. One hundred and seventeen patients with DRFs, with and without radiographic SL-widening, and treated with volar locked plating, were prospectively enrolled.
