sex reprod

Sexual reproduction imposes long and annoying formalities, such as searching and courting a partner. But it is definitely worth it: the genetic mixing prevents the appearance of dangerous mutations and increases the chances of fighting parasites and pathogens. Once again, someone has spoken in favor of sex: a group of researchers from the University of Montpellier has claimed that its evolution could have been driven by the need to combat transmissible tumors.

phage therapy

A 15-year-old girl with cystic fibrosis who suffered from an antibiotic-resistant mycobacterium infection has been treated thanks to a "modern" therapeutic approach, phage therapy. Not so modern actually, given that the first experiments date back to the 20s of the last century. But it has only recently been rediscovered and proposed as a valid alternative to antibiotic therapy, especially in the case of resistant bacteria, which are going to become more and more threatening.

They are in fact the only wild species in the world in which a form of Alzheimer has been found, which is similar to the human one. A "natural" model that has raised the interest of scientists, opening a new line of research that helps to combat the disease even in humans.

nanobodies alpacas CART

They are funny to look at, mild and intelligent: that was what we knew about alpacas until 1989. That year, two students discovered by chance one important feature that has long remained unknown. This and other species belonging to camelid family have "miniature" antibodies: smaller than ours and those of most mammals, they can reach even the most difficult targets. Researchers at Boston Children 's Hospital used the so called “nanobodies” to make CAR-T cells better at solid tumors. The study has been published in the journal PNAS.
