Understanding how chikungunya virus affects the brain and body
Publicado em 13 de março de 2024
The chikungunya virus, transmitted by and Aedes albopictus mosquitoes and responsible for more than 900 deaths in Brazil since it arrived around ten years ago, is capable of spreading through the blood, reaching multiple organs and crossing the blood-brain barrier, which protects the central nervous system. The mechanisms of action observed for the first time in fatal cases by a group of Brazilian, American and British researchers were reported in an article published on March 12 in the journal [...]

Chikungunya Virus Causes Death by Attacking Organs, Dysregulating Immunity: Study
Publicado em 13 março 2024The chikungunya virus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes and responsible for more than 900 deaths in Brazil since it arrived around ten years ago, is capable of spreading through the blood, reaching multiple organs and crossing the blood-brain barrier, which protects the central nervous system. The mechanisms of action observed for the first time in fatal cases by a group of Brazilian, American and British researchers were reported in an article published on [...]Mirage News (Austrália) -
Brazilian Scientists Discover Hydrogen Production Material
Publicado em 13 março 2024Hydrogen (H2) is considered a possible alternative to fossil fuels, which are responsible for a large proportion of atmospheric emissions and global warming, but production costs must be lowered if it is to become a viable option. In an article published in the journal Electrochimica Acta, scientists at the Center for Development of Functional Materials (CDMF), a Research, Innovation and Dissemination Center (RIDC) funded by FAPESP and hosted at the Federal University [...]Mirage News (Austrália) -
Predicting Urban Tree Failure: Wood Condition, Root Constriction, Improper Pruning
Publicado em 13 março 2024In São Paulo, Brazil's largest metropolis, the city center is considered a tree failure hotspot, with the largest proportion of failures in the city occurring in that area. The main predictors of tree failure are the condition of the wood, constriction of the roots by the sidewalk, and drastic pruning, concludes a study recently published in the journal Urban Forestry & Urban Greening. The authors analyzed data for 456 tree failures in the central area of [...]Mirage News (Austrália) -
Nanoemulsion Curcumin Tested for Intestinal Inflammation Cure
Publicado em 07 março 2024A nanoemulsion containing particles of curcumin, which is known to have anti-inflammatory and antioxidant properties, was found capable of modulating the gut microbiota of mice with intestinal inflammation in experiments conducted by researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil. The study was supported by FAPESP (projects 22/12823-0, 20/15185-0 and 17/03879-4), and is reported in an [...]Mirage News (Austrália) -
Scientists discover that a protein associated with neurodegenerative diseases is also linked to childhood brain cancer
Publicado em 06 março 2024A protein that has been widely studied owing to its association with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) is also linked to medulloblastoma, a type of central nervous system cancer. Medulloblastoma is one of the most common and aggressive brain tumours in children, arising from undifferentiated cells during early neural development. A study led by a group of Brazilian scientists has shown in vitro and in vivo that the gene VAPB is linked to cell [...]Oncology News (Austrália) -
Study finds link between freezing of gait and sleep disorders in Parkinson's patients
Publicado em 05 março 2024Parkinson's disease patients who experience freezing of gait (a sudden inability to initiate or continue movement, often resulting in a fall) wake up several times during the night, feel sleepy during the day, and have REM sleep behavior disorder. Rapid eye movement (REM) sleep plays a role in the maintenance of many cognitive processes. These are key findings of a study supported by FAPESP and conducted by researchers at São Paulo State University (UNESP) in Brazil and Grenoble [...]News Medical (Austrália) -

'Study: Soil Microorganisms Return After Semi-Arid Area Restoration'
Publicado em 05 março 2024Strategies deployed for the restoration of degraded land have had promising results in Brazil's semi-arid region, improving the microbial properties of the soil and contributing to a return of native ecosystem services. The techniques include removal of cattle or restriction of their access to specific areas of pasture; cultivation of cover crops; and terracing to control erosion. Recovery of soil microbial properties maintains biodiversity and raises crop yields, contributing to [...]Mirage News (Austrália) -
Glitter Has a Dark Side, And It's Causing Even More Harm Than We Realized
Publicado em 04 março 2024All that glitters is not gold. Actual glitter, for instance, can be a surprisingly harmful environmental pollutant, as a new study demonstrates. Despite its association with fun and frivolity, glitter has a dark side. Flecks of glitter reduce the amount of sunlight that penetrates into bodies of water, the new study shows, potentially impairing the ability of some aquatic plants to photosynthesize. Glitter is essentially a microplastic in disguise, whose whimsical nature distracts from [...]ScienceAlert (Austrália)
