Animal testing will no longer be required to assess a group of deadly neurotoxins, thanks to University of Queensland-led research.
Many life-threatening bacteria are becoming increasingly resistant to existing antibiotics. Swiss researchers co-headed by the University of Zurich have now discovered a new class of antibiotics with a unique spectrum of activity and mechanism of action – a major step in the fight against antimicrobial resistance. By disrupting outer membrane synthesis, the antibiotics effectively kill Gram-negative bacteria.
Synthetic or engineering biology involves genetically engineering not only yeast and bacteria but also plants, animals and humans. The benefits could be immense, ranging from gene therapy for disease to improved crops and better medicines.
Scientists have used an experimental therapy that relies on bacteria-infecting viruses collected, in part, through HHMI’s SEA-PHAGES program to fight a Mycobacterium infection in a 15-year-old girl.
In a proof-of-principle study in mice, scientists at Johns Hopkins Medicine report the creation of a specialized gel that acts like a lymph node to successfully activate and multiply cancer-fighting immune system T-cells.
Through pioneering clinical research, Embryotools, based in the Barcelona Science Park, and Institute of Life in Athens have achieveg birth of the world’s first healthy baby through the pioneering Maternal Spindle Transfer method to solve infertility problems. This technique was implemented by the Greek IVF center and Spanish research center to address fertility issues associated with multiple in vitro fertilization (IVF) failures caused by cytoplasmic dysfunction of the oocytes or rare mitochondrial genetic diseases.
Scientists build artificial cells as models of primitive cells. ELSI scientist and colleagues have constructed artificial cells using minimal components that are able to supply energy to drive gene expression inside a microcompartment, thus these artificial cells can produce energy that helps synthesize parts of the cells themselves.
