Antibiotic resistance is a global concern that threatens our ability to prevent and treat bacterial infections in humans and animals. To better monitor the emergence and spread of resistance, researchers at the Carl R. Woese Institute for Genomic Biology developed a CRISPR-enriched metagenomics method for the enhanced surveillance of antibiotic resistance genes, ARGs, in wastewater.

Researchers at the University of Calgary are suggesting a more comprehensive approach for identifying at-risk wildlife populations — such as caribou — based on individual movement patterns. The paper, published on Feb. 20 in the journal Biological Conservation, uses a long-term dataset of caribou wearing GPS collars across Western Canada. It identifies six distinct behavioural groups that would each deserve their own conservation actions.

A recent review in Engineering explores multi-photon 3D nanoprinting. This technology, with its unique 3D processing and nanoscale resolution, has wide applications in fields like optics and biology. However, it faces challenges such as slow processing speed and material limitations. The article also looks at potential solutions and future development directions, offering insights into the future of this technology in manufacturing.

Adipose tissues, which serve as fat reserves, have been recognized as an endocrine organ. The three-dimensional (3D) bioprinting of adipose tissues has potential applications in regenerative medicine. However, the 3D bioprinting conditions have not been optimized for adipose tissues. Now, researchers from Korea have developed a novel method for 3D adipose tissue bioprinting using a hybrid bioink. The 3D bioprinted adipose tissues exhibited skin regeneration ability, paving the way for their applications in regenerative medicine.

Chinese scientists from Prof. ZHOU Jianmin's team at the Institute of Genetics and Developmental Biology revealed that a widespread plant defense metabolite may help combat bacterial diseases in crops.

　How did mammalian faces evolve from reptilian ones? Our study describes the morphological details of mouse craniofacial development, challenging the view that mammals and reptiles share the same jaw structure pattern. We show that mammals lost a reptile-like ancestral jawbone, reorganizing their upper jaw and transforming the ancestral jaw tip into an independent nose. These findings enhance our understanding of facial evolution and provide new insights into human craniofacial development and disorders.
