Organisms with complex visual systems rarely respond to just the sum of all visual stimuli impinging on their eyes. Often, they restrict their responses to stimuli in a temporarily selected region of the visual field (selective visual attention). Here, we investigate visual attention in the fly Drosophila during tethered flight at a torque meter. Flies can actively shift their attention; however, their attention can be guided to a certain location by external cues. Using visual cues, we can direct the attention of the fly to one or the other of the two visual half-fields. The cue can precede the test stimulus by several seconds and may also be spatially separated from the test by at least 20° and yet attract attention. This kind of external guidance of attention is found only in the lower visual field.

Managing plastic waste is one of the greatest challenges humanity faces in the coming years. Current strategies-landfilling, incineration, and recycling-remain insufficient or pose significant environmental concerns, failing to address the growing volume of plastic residues discharged into the environment. Recently, increasing attention has focused on the potential of certain insect larvae species to chew, consume, and partially biodegrade synthetic polymers such as polystyrene and polyethylene, offering novel biotechnological opportunities for plastic waste management.

: Larval therapy (LT), an intervention using live fly larvae to remove necrotic tissue and promote healing, has regained attention in order to address the growing need for chronic wound management. LT was approved by the Food and Drug Administration (FDA) in 2004 to treat difficult-to-heal wounds; however, LT remains an underutilized therapy. To evaluate efficacy of LT in a systematic review and meta-analysis of wound outcomes from randomized controlled trials (RCTs).

College of Ecology and Environment, Xinjiang University, Urumqi 830046, China.
The objective of this investigation is to overcome the difficulties in fabricating cost-effective, eco-friendly porous geopolymers (PGs) by integrating Coal fly ash (CFA) and spodumene flotation tailings (SFT). This synthesis utilizes a unique blend of CFA and SFT in a 6:4 mass ratio, with specific attention to optimizing the pore architecture to improve the PGs' efficacy. Key parameters included a modulus of 1.

Enhanced sampling (ES) simulations of biomolecular recognition, such as binding small molecules to proteins and nucleic acid targets, protein-protein association, and protein-nucleic acid interactions, have gained significant attention in the simulation community because of their ability to sample long-time scale processes. However, a key challenge in implementing collective variable (CV)-based enhanced sampling methods is the selection of appropriate CVs that can distinguish the system's metastable states and, when biased, can effectively sample these states. This challenge is particularly acute when the binding of a flexible molecule to a conformationally rich host molecule is simulated, such as the binding of a peptide to an RNA.

As is widely accepted, cumulative strain and improvement mechanisms of stabilized soil are critical factors for the long-term reliable operation of expressways and high-speed railways. Based on relevant research findings, xanthan gum biopolymer is regarded as a green and environmentally friendly curing agent in comparison to traditional stabilizers, such as cement, lime, and fly ash. However, little attention has been devoted to the cumulative strain and improvement mechanisms of soil reinforced by xanthan gum biopolymer under traffic loading.
