CRISPR as a Recorder of Molecular Activity

Researchers from Harvard University have succesfully proved that CRISPR can work as a recorder of molecular events. Synthetic DNA molecules introduced in bacteria over a defined timespan were integrated by the CRISPR/Cas system in DNA arrays in the exact same order of introduction. The results, published in the journal Science, pave the way for using CRISPR to […]

Sanofi Pasteur Launches a Zika Virus Vaccine Project

Sanofi Pasteur, the vaccines department of Sanofi, has announced a project to develop a vaccine against the Zika virus (ZIKV). The company will leverage their expertise in the development of vaccines against similar viruses like dengue, yellow fever and Japanese encephalitis. Sanofi’s research and development expertise and industrial infrastructure -crucial to create Dengvaxia, their licensed vaccine […]

Nanopore Diagnostics Raises $600000 to Develop the iNDxer

American startup Nanopore Diagnostics has raised $600000 to develop The iNDxer, a device to detect bacterial infections. The money, provided by the Missouri Technology Corporation and other minor investors, will be allocated to conduct clinical trials that will validate the use of the Nanopore Diagnostics’ device by physicians. Nanopore Diagnostics CEO Tom Cohen was mistakenly […]

Proteins That Act as Superglue Connect Virus-Like Particles to Epitopes

Researchers from Oxford University have developed a new technique to create new vaccines faster and more effectively. The scientists used a ‘bacterial superglue’ made of two strongly interacting proteins that are attached to a virus-like particle (VLP) and to an antigen, respectively. The new tool will allow to lower costs of vaccine development and to quickly work […]

Human Faeces Transplanted to Treat Obesity

Researchers from the Massachusetts General Hospital will conduct a clinical trial for weight loss based on human faeces. Pills filled with excrements from healthy people will be freeze-dried and introduced in 21 obese patients during the trial. The scientists expect fecal bacteria from the lean people to colonize the patient’s intestines and help them overcome obesity. Several […]

Gabriel Ortega: “How Do Halophiles Endure Extreme Salinity?”

The slow but unstoppable progress of evolution has enabled, step by step, mutation after mutation, the conquest of virtually all ecosystems on Earth. Even in those places where conditions are far from “standard”, where the presence of organisms seems unthinkable, life has found its way. These small conquerors are called extremophiles. Thus we find thermophilic organisms that […]

Global Seaweed Shortage Forces Companies to Ration Agar

A global shortage of red algae seaweed has forced Thermo Fisher Scientific to ration supplies of agar, the growth medium used in laboratories to culture bacteria and fungi. Merck has stopped selling it as a raw material, although keeps selling it as dehydrated culture media. The lack of availability is due to fluctuating seaweed yields […]

Genome Editing Cures Muscular Dystrophy in Mice

Researchers from Duke University have used the CRISPR technology to cure Duchenne muscular dystrophy in a mouse. It is the first time that the gene editing technology is successfully used to treat an adult mammalian. The study, published in the journal Science, establishes CRISPR/Cas9 as a potential therapy for the treatment of muscular dystrophy in humans. Duchenne […]
