Researchers have found that young adults who skip breakfast are more likely to gain weight than those who do not. They also found that teenagers who miss the first meal of the day have an average higher waist compared to those who eat breakfast. Researchers associated with the medical school of the University of São Paulo in Brazil and colleagues from institutions in Europe have suspected that skipping breakfast can lead to an unbalanced diet and other unhealthy habits that increase the [...]

Using the protein produced by the fungus inhabiting the Amazon, Brazilian scientists have developed a molecule capable of increasing the release of glucose from biomass for fermentation One of the main challenges associated with the production of second generation biofuels is the identification of enzymes produced by microorganisms for use in an enzyme cocktail to catalyze the hydrolysis of biomass, in which enzymes work together, for example to break down carbohydrates in the garbage and [...]

Smoking powerful dagga each day can increase the chances of developing psychosis almost five times, according to the largest ever study of the effect of cannabis on indicators of psychotic disorders. Research supplements previous studies that have shown links between marijuana and mental health problems, but they still do not define marijuana as a cause. Psychotic disorders – in which people lose touch with reality – are usually caused by factors, including genetics and the environment. [...]

The fall of amphibians? The rapid spread of the disease is a threat in our connected world. Sly fungus Batrachochytrium dendrobatidis was identified in amphibian populations about 20 years ago and caused species death and extinction on a global scale. Scheele et al. found that the fungus caused declines in the amphibian population everywhere, except its origin in Asia (see perspective of Greenberg and Palen). Most species and populations are still experiencing decline, but there is evidence of [...]

Researchers at the University of São Paulo in Brazil have discovered a way to decontaminate organs for transplants through a novel method that uses light to kill viruses and bacteria from a donor. According to specialists, bio-photon therapy, as it is known, should extend the possibilities of available organs and reduce the complications after surgery. "Currently, there is no decontamination of organs for transplants, only withdrawal of blood, but microorganisms are still alive, or the organ [...]

Daily use of cannabis is associated with a much higher risk of developing psychosis, according to a case-control study at the Lancet Psychiatry. some 900 adults who presented the first episodes of psychosis in 11 places in Europe and Brazil were compared with 1200 controls based on a population without psychosis. Participants completed questionnaires on the use of cannabis throughout their lives; in the analyzes the reported tetrahydrocannabinol (THC) concentration in cannabis in different [...]

Although neglected diseases account for 11% of global disease burden, they are the target of only a small portion of the new drugs being developed each year. Between January 2012 and September 2018. 256 new drugs entered the market, but only eight (3.1%) were developed to treat neglected diseases. This value exceeds the ratio for 1975-99, which was 1.1%, but is lower than 4.3% recorded in 2000-11. The term "neglected diseases" refers to malaria, diarrheal diseases, tuberculosis and 20 [...]

Consuming low-calorie foods may have a protective effect against certain diseases, because the number of calories that a person directly affects the functioning of different cells, say the researchers. A study in mice has shown that a low calorie diet can protect the brain from nerve cell death associated with diseases such as Alzheimer's disease, Parkinson's disease, epilepsy and cerebrovascular accident (CVA). "We are investigating how changes in diet affect metabolism and how it changes [...]
