Ischemic stroke after COVID-19 bivalent vaccine administration in patients aged 65 years and older in the United States
Abstract The Centers for Disease Control and Prevention announced in January 2023 a potential connection between administration of the Pfizer novel coronavirus disease-2019 (COVID-19) bivalent vaccine booster and ischemic stroke (IS). A retrospective cohort study was conducted to compare the hazard of IS in patients aged 65 years and over administered the Pfizer bivalent booster…

Réunion’s search for energy self-sufficiency
Valentin Russeil was studying in Paris in 2018 when protests against the rising cost of living and 24% unemployment broke out on the island of Réunion. The island is an overseas department of France, located east of Madagascar. Russeil, who is from Réunion, followed the news closely and spoke to his family back home every…

A conceptual design of circular adaptive façade module for reuse
Abstract Climate change has an impact on the ecosystem, and subsequently, it affects the built environment. Building envelope has a vital role in controlling the integration between indoor and outdoor environmental quality. The responsivity of the façade has proven its efficiency in optimizing the global energy performance of buildings. Adaptive façades are multifunctional reconciling envelope…

The most powerful cosmic ray since the Oh-My-God particle puzzles scientists
Researchers check the Telescope Array surface detector in the high desert in Delta, Utah, USA in 2019. In 2021, the Telescope Array detected the second-most energetic cosmic ray particle recorded.Credit: The Yomiuri Shimbun via AP/Alamy Scientists have detected the most powerful cosmic ray seen in more than three decades. But the exact origin of this…

‘Treasure trove’ of new CRISPR systems holds promise for genome editing
The CRISPR–Cas9 system (pictured) is used to find and cut specific DNA sequences.Credit: Carlos Clarivan/Science Photo Library CRISPR–Cas9 is best known as a laboratory tool for editing DNA, but its natural function is as part of the immune system that helps microorganisms to fight off viruses. Now, researchers have used an algorithm to sort through…

Comparison of measurements made on dry bone and digital measurements in Anatomage for the sacral bone in a Spanish population
Abstract The use of osteometry for human identification is a key element in the field of forensic sciences. Currently, the osteometry focuses on the use of digital techniques such as photography or 3D scans, to study and measure bones, offering advantages like easy access, preservation of bones, and worldwide collaboration possibilities. The study aims to…

Annular one-dimensional photonic crystals for salinity sensing
Abstract The use of annular one-dimensional (1D) photonic crystals (PCs) for salinity sensing is studied in this research. Annular 1D-PCs provide small and integrated structures that facilitate the creation of portable and miniaturized sensor equipment appropriate for field use. In order to generate annular 1D-PCs, the research explores the finite element method (FEM) simulation technique…

Is clonal hematopoiesis ‘mostly harmless’?
Whole-genome sequencing data of individuals from the UK Biobank and Iceland and a somatic mutation barcoding strategy enabled detection of clonal hematopoiesis at scale. This comprehensive study provides insights into the epidemiology, somatic and germline genetics, and disease associations of clonal hematopoiesis. This is a preview of subscription content, access via your institution Access options…

The effects of precipitation change on urban meadows in different design models and substrates
Abstract Climate change, such as temperature and precipitation changes, is becoming increasingly obvious, and in this context, planting designs need to urgently consider future climate change in advance. A field experiment was conducted in Beijing, China, where the future precipitation is predicted to increase, and extra irrigation was used to simulate the future precipitation increase.…
