Large‐Aperture Polarization‐Independent Broadband Achromatic All‐Dielectric Metalens for Terahertz Focusing

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
A large‐aperture, high focusing efficiency and polarization‐independent THz single‐layer achromatic metalens is reported via discrete multi‐wavelength achromatic design and global optimization algorithm. The fabricated metalens exhibits a largest diameter of 2.21 cm, excellent achromatic performance, extremely high average focusing efficiency (> 46 ...

Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Intestinal Ultrasound of Adult Small Bowel Intussusception Caused by a Polyp: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
Intestinal ultrasound findings in adult small bowel intussusception caused by a polyp. ABSTRACT Intestinal ultrasound may facilitate early diagnosis of adult small bowel intussusception and can directly demonstrate a pathological lead point such as an intraluminal polyp. In patients with nonspecific abdominal symptoms, this may expedite CT confirmation,

Transcriptomic and DNA Methylation Profiles of Alternative Aphid Morphs and Genotypes

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Graph showing the correlation between differentially expressed genes and differentially methylated genes. There is no correlation between gene expression and DNA methylation level in pea aphid polyphenism. ABSTRACT Pea aphids can develop alternative morphs when exposed to stressful conditions, showing differences between genotypes in their stress ...
