Understanding of mechanisms behind post-exercise lack of appetite can open new paths to obesity treatment
Publicado em 26 de setembro de 2023
Obesity is a growing concern worldwide, and it is associated with several health problems such as diabetes, heart disease, and cancer. While there are several factors that contribute to obesity, one of the most significant is overeating. Overeating can be caused by a lack of appetite control, which can be influenced by several factors, including exercise.
After exercising, many people experience a lack of appetite, which can be beneficial for weight loss. However, for some people, this lack [...]

Copper-based catalysts efficiently turn carbon dioxide into methane
Publicado em 25 setembro 2023The lab of Rice University materials scientist Pulickel Ajayan and collaborators developed a way to wrest the carbon from carbon dioxide and affix it to hydrogen atoms, forming methane ⎯ a valuable fuel and industrial feedstock. According to the study published in Advanced Materials, the method relies on electrolysis and catalysts developed by grafting isolated copper atoms on two-dimensional polymer templates. “Electricity-driven carbon dioxide conversion can produce a large array [...]ver notícia -
Cell therapy can reduce risk of death from COVID-19 by 60%, study finds
Publicado em 18 setembro 2023A recent study has found that cell therapy can reduce the risk of death from COVID-19 by 60%. This is a significant finding that could potentially save many lives. The study was conducted by researchers at the University of Maryland School of Medicine. They used a type of cell therapy called mesenchymal stem cell (MSC) therapy. MSCs are a type of cell that can be found in bone marrow and other tissues in the body. They have the ability to reduce inflammation and promote tissue repair. The [...]ver notícia -
Researchers track yeast population dynamics in fuel bioethanol production
Publicado em 30 agosto 2023Researchers from the University of Illinois have developed a new method to track the population dynamics of yeast in fuel bioethanol production. The study, published in the journal Biotechnology for Biofuels, could help improve the efficiency and sustainability of bioethanol production. Bioethanol is a renewable fuel made from plant materials such as corn, sugarcane, and switchgrass. Yeast is used to ferment the sugars in these materials into ethanol. However, the yeast population can be [...]ver notícia -
Sanitized Ready-To-Eat Salad May Contain Disease-Causing Bacteria: Research
Publicado em 29 agosto 2023Washington DC [US], August 30 : A review paper published in the journal Foods describes a study that provides an overview of studies on minimally processed vegetables (MPVs), with a particular focus on the Brazilian market. Data is presented on hygiene indicators and pathogenic microorganisms, especially Escherichia coli (the main indicator of fecal contamination), Salmonella spp., and Listeria monocytogenes, with prevalence rates ranging from 0.7 per cent to 100 per cent, 0.6 per cent to [...]ver notícia -
Sleep apnea accelerates aging, but use of breathing therapy method can mitigate the problem
Publicado em 23 agosto 2023Sleep apnea is a common sleep disorder that affects millions of people worldwide. It is characterized by pauses in breathing during sleep, which can lead to a range of health problems. One of the lesser-known effects of sleep apnea is that it can accelerate the aging process. Studies have shown that people with sleep apnea have shorter telomeres than those without the disorder. Telomeres are the protective caps on the ends of chromosomes that shorten as we age. Shorter telomeres are [...]ver notícia -
Novel enzyme could boost sustainable production of aviation fuel
Publicado em 16 agosto 2023Researchers at the University of Bristol have discovered a new enzyme that could help boost the sustainable production of aviation fuel. The enzyme, called cytochrome P450 BM3, has the ability to convert fatty acids into hydrocarbons, which can be used as a sustainable alternative to traditional aviation fuel. The aviation industry is one of the largest contributors to greenhouse gas emissions, and finding sustainable alternatives to traditional aviation fuel is crucial in reducing its [...]ver notícia -
Study proposes use of artificial intelligence to diagnose autism spectrum disorder
Publicado em 15 agosto 2023Diagnosing autism spectrum disorder (ASD) is still a daunting challenge because of the degree of complexity involved, requiring highly specialized professionals. Autism is a multifactorial neurodevelopment disorder with widely varying symptoms. In the United States, about 1 in 36 children have been diagnosed with ASD, according to the Centers for Disease Control and Prevention (CDC), and yet there are no biochemical markers to identify it with precision. A quantitative diagnostic method is [...]ver notícia -
Novel Socio-Environmental Vulnerability Index Pinpoints Sustainability Issues In Brazilian River Basins
Publicado em 10 agosto 2023A new study has developed a novel socio-environmental vulnerability index to identify sustainability issues in Brazilian river basins. The study, published in the journal Environmental Science and Policy, used data from the Brazilian Institute of Geography and Statistics to assess the vulnerability of river basins to environmental and social stressors. The index takes into account factors such as deforestation, water pollution, and social inequality to provide a comprehensive picture of the [...]ver notícia -
Rare long-distance dispersal events found to help maintain genetic structure of mangroves
Publicado em 09 agosto 2023In Brazil's North region, members of the population of red mangrove trees (Rhizophora mangle) do not often meet relatives from the South and vice-versa. However, occasional migrations via ocean currents between the two regions involving propagules, seeds adapted to seawater, enable populations to exchange genetic material and remain connected during their evolution. This is one of the conclusions of a study reported in the journal by Brazilian and Japanese researchers. Mangrove [...]ver notícia
