Echolocating bats rely on rapid processing of auditory information to guide moment-to-moment decisions related to echolocation call design and flight path selection. The fidelity of sonar echoes, however, can be disrupted in natural settings due to occlusions, noise, and conspecific jamming signals. Behavioral sensorimotor adaptation to external blocks of relevant cues has been studied extensively, but little is known about adaptations that mitigate internal sensory flow interruption.

The optimal repair of rigid mineralized tissues, such as bone, in cases of fracture, surgical resection, or prosthetic placement, is a complex process often necessitating the use of bone graft materials. Autogenous bone from the patient is generally the gold standard in terms of outcomes but also has disadvantages, which have resulted in extensive research in the field of tissue engineering to develop better and more convenient alternatives. In the dental field, several initiatives have demonstrated that the dentin material derived from extracted teeth produces excellent results in terms of repairing bone defects and supporting dental implants.

Article Synopsis
  • Precise control of the arrangement of materials is crucial for improving the efficiency of nonlinear optical (NLO) functions, particularly for second-harmonic generation (SHG) and the optical bandgap.
  • A new strategy is introduced, transitioning from zero-dimensional (0D) to three-dimensional (3D) structures, to enhance broadband SHG responses, demonstrated through the synthesis of a novel 3D pseudo diamond-like Zn(SCN).
  • This new material exhibits significantly improved SHG responses across a wide range of wavelengths, outperforming previous NLO materials, thanks to the unique arrangement of connected building blocks within its diamond-like structure.

Medication-induced osteoporosis leads to substantial fracture morbidity. With polypharmacy and the aging population in the United States, significant increases in medication-associated fractures are predicted. The most common medication to cause osteoporosis and increase fractures is glucocorticoids.

Inflammatory bowel disease (IBD) is a chronic disorder characterized by recurrent gastrointestinal inflammation, lacking a precise aetiology and definitive cure. The gut microbiome is vital in preventing and treating IBD due to its various physiological functions. In the interplay between the gut microbiome and human health, extracellular vesicles secreted by gut bacteria (BEVs) are key mediators.
