Could we feed a city on Mars? This question is central to the future of space exploration and has serious repercussions on Earth too. To date, a lot of thought has gone into how astronauts eat; however, we are only beginning to produce food in space. Space launches are quite expensive. And with the growing […]
Recently, the results of an early human phase clinical trial have shown that mRNA technology can be successfully applied to diseases other than COVID-19, such as skin cancer. Moderna and Merck used an mRNA anti-cancer vaccine based on the same technology used to develop some COVID-19 vaccines, except that instead of using proteins from a […]
Bringing together concepts from electrical engineering and bioengineering tools, scientists have produced genetic “devices” designed to perform neuromorphic computations like artificial neural circuits in bacterial cells. The genetic material was inserted into bacterial cells in the form of a plasmid: a relatively short DNA molecule that remains separate from the bacteria’s “natural” genome. Plasmids also […]
Scientists have created the world’s first monkey embryos containing human cells in an attempt to investigate how the two types of cell develop alongside each other. The embryos, which were derived from a macaque and then injected with human stem cells in the lab, were allowed to grow for 20 days before being destroyed. We […]
Both the depletion of fossil fuels and the environmental concerns are a powerful drive for the development of sustainable routes to commodity chemicals. Lignocellulose, comprised of lignin, cellulose and hemicellulose, is the ideal candidate, but its inherent complexity hampers its transformation to value-added chemicals. The group of Katalin Barta at the University of Groningen has […]
Every organism, from virus to animals need nitrogen (N) to live; indeed, nucleic acids and proteins are made out with N. Nearly all of these organisms, fulfill their nitrogen needs taken up N from the environment in reduced forms, usually as nitrate (NO 3 – ), ammonium (NH 4 + ) or amino acids. Interestingly […]
The other day I came across an article about the revolution of cultured meat at El País Semanal, although that was not the first time I read about this. Still, I have to admit is such a shocking subject that I thought it may deserve a post explaining how advanced this technology is at the […]
It seems that we are definitely heading towards the bio-based society, a new way of interacting with the environment where fossil fuels won’t be needed anymore and “ more natural ” processes for producing energy, food and materials will prevail. Remarkably, this bio-turn often involves highly advanced biotechnology and strict competitive targets, both facts that […]
It all began in 1891, when Dr. William B. Coley, a bone sarcoma surgeon at the Memorial Hospital in New York, injected streptococcal organisms into a patient with inoperable cancer. He thought that the infection he induced would have the side effect of shrinking the malignant tumor… and quite surprisingly he was right! The patient’s […]

Ever since the 1993 film based on Michael Crichton’s novel Jurassic Park was released, the thought of reviving extinct species using molecular biology techniques has been on the forefront of the collective imaginary. The idea seemed pretty simple: reading the genetic code of fossilized animals would provide the instruction manual to bring them back to […]
