With aging, mutant genetic material tends to build up in the organelles responsible for producing energy, and this can lead to disease. Brazilian researchers have discovered that a cell cleansing mechanism known as autophagy can modulate this phenomenon.

A group of international researchers are proposing a new wiring diagram to show the interrelationships of the physiological traits that impact wheat yield potential. By illustrating these linkages, it shows connections among traits that may not have been apparent, which could serve as a decision support tool for crop scientists. Raising yields must be an integral component of making crops more climate-resilient, to ensure food and nutritional security in the future. This new tool can inform new research hypotheses and breeding decisions, as well as research investment areas, to achieve these goals.

The Patagonian sheepdog (PGOD) originated from the ancestral shepherds of the United Kingdom is nowadays the closest link to a now extinct population of shepherds from which modern herding breeds descend.

Experiments involving isolated and cultured cells as well as animals and babies suggest that short-chain fatty acid acetate produced in the gut can minimize the effects of infection by respiratory syncytial virus.

Devices that combine laser irradiation, ultrasound and suction help regenerate tissue and treat muscle, joint, skin, neurological and lung damage. Protocols created via business-university partnerships are being tested and can be applied by treatment centers across Brazil.

Researchers have discovered that infection occurs in two stages. The fungus first releases cytokinin and makes the tree produce lignin, its favorite food. In the second, the fungus consumes the lignin.

In tests conducted at the University of São Paulo, microparticles produced from the unripe fruit performed similarly to TBHQ, a synthetic compound present in processed foods and in cosmetics.
