Science News | Artificial Intelligence Aids in Predicting Sugarcane Field Performance: Study
Publicado em 19 de outubro de 2022
Washington [US], October 20 (ANI): According to a Brazilian study published in Scientific Reports, artificial intelligence (AI) can be used to develop efficient models for the genomic selection of sugarcane and forage grass varieties and predict their field performance based on their DNA.
In terms of accuracy compared with traditional breeding techniques, the methodology developed with support from FAPESP improved predictive power by more than 50%. This is the first time a highly efficient [...]

Protein restriction may be useful in reducing obesity, diabetes: Study
Publicado em 21 setembro 2022According to a study, reducing protein consumption can help regulate metabolic syndrome and some of its key symptoms, such as obesity, diabetes, and high blood pressure (hypertension). An article reporting the study is published in the journal Nutrients. Metabolic syndrome is a cluster of conditions that heighten the risk of cardiovascular disease, stroke and diabetes, including hypertension, high blood sugar, excess body fat around the waist and abnormal cholesterol levels.

Pyramidal neurons that gauge speed, location identified during research
Publicado em 18 setembro 2022Washington [US], September 18 (ANI): More than a decade after the role of pyramidal neurons in mental representations of space and location was discovered, a group of researchers have identified a subtype of neurons that can gauge speed with great precision. “In experiments involving animals, we demonstrated an association between the electrical activity of inhibitory interneurons and speed representations in the brain,” Alexandre Kihara, a neuroscientist at the Federal [...]ver notícia -
Researchers discover pyramidal neurons that gauge speed, location
Publicado em 15 setembro 2022Washington [US], September 15 (ANI): A group of researchers has made an important contribution to scientists’ understanding of the brain’s navigation system by identifying a subtype of these neurons that can gauge speed with great precision, more than a decade after the role of pyramidal neurons in mental representations of space and location was discovered. “In experiments involving animals, we demonstrated an association between the electrical activity of inhibitory [...]ver notícia -
Study describes how COVID-19 damages the brain
Publicado em 12 agosto 2022Washington [US], August 12 (ANI): A study shows how SARS-COV-2 infects brain cells called astrocytes, causing structural changes in the brain. Infection with SARS-CoV-2 can cause brain alterations and neurocognitive dysfunction, particularly in long COVID-19 syndrome, but the underlying mechanisms are elusive. Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. The authors [...]ver notícia -
Research finds how different smells influence visual perception of emotions
Publicado em 12 agosto 2022Washington [US], August 12 (ANI): The findings of master’s research by Matheus Henrique Ferreira, currently a PhD candidate at the University of Sao Paulo’s Institute of Psychology (IP-USP) in Brazil, suggest that smells influence our ability to see and interpret the emotions of other people, even when we are unaware of the odour in question. An article with detailed measurements of this effect is published in the journal PLOS ONE. “If I’m subjected to a pleasant [...]ver notícia -
Scientists discover new technique to convert methane gas into liquid methanol
Publicado em 03 agosto 2022Washington [US], August 3 (ANI): According to new research, scientists have discovered a new technique of converting methane gas into methanol using light and dispersed transition metals such as copper. As per a study published in Chemical Communications, the reaction was the best obtained to date for the conversion of methane gas into liquid fuel under ambient conditions of temperature and pressure (25 °C and 1 bar respectively). The term bar as a unit of pressure derives from the [...]ver notícia -
Study: Novel coronavirus manipulates cells to replicate
Publicado em 18 julho 2022Sau Paulo [Brazil], July 19 (ANI): An article published in the journal 'Frontiers in Cellular and Infection Microbiology' describes a study conducted by researchers at the State University of Campinas (UNICAMP) and the University of So Paulo (USP) in Brazil that demonstrates how a human protein interacts with a SARS-CoV-2 protein, as well as one of the ways the virus that causes COVID-19 recruits cells to replicate. In laboratory tests, the researchers used a drug to inhibit the [...]ver notícia -
Study explains harmful effects of ultra-processed foods on adolescents
Publicado em 17 abril 2022Sao Paula [Brazil], April 17 (ANI): Higher consumption of ultra-processed foods is strongly associated with an increased weight gain. Researchers at the University of Sao Paulo have calculated the impact of adolescents consuming ultra-processed foods on the risk of obesity. The findings of the study were published in the journal, ‘Journal of the Academy of Nutrition and Dietetics’. There are 3,587 adolescents aged 12-19 who took part in the 2011-16 National Health and [...]ver notícia -
Adolescents consuming ultra-processed foods are at risk of obesity: Study
