Wildfires Char 30% of Pantanal in 2020
Publicado em 17 de outubro de 2023
In 2020, the Pantanal, the largest tropical freshwater wetland in the world and a biodiversity hotspot, was swept by high-intensity fires that destroyed native vegetation in an area totaling 44,998 square kilometers (km²), or about 30% of the Brazilian portion of the biome, which spans some 150,000 km². The estimate is presented in an article published in the science journal Fire.
The area destroyed by that year's disastrous fires was far larger than had been thought, according [...]

Uncharted Brazilian Amazon Areas Lack Ecological Research: Study
Publicado em 16 outubro 2023Many parts of the Brazilian Amazon are neglected in ecological research, for several reasons, according to an article published in the journal Current Biology. Authored by Joice Ferreira of the Federal University of Pará (UFP) and colleagues from many countries who also belong to the Synergize Consortium, the article identifies the areas missing from ecological research and the factors that have determined these gaps, pinpointing opportunities for the planning of new investments in [...]Mirage News (Austrália) -
Cerrado requires strict protection and rehabilitation of areas to curb deforestation, scientists warn
Publicado em 11 outubro 2023The fast pace at which natural vegetation is being destroyed in the Cerrado, Brazil’s savanna-like biome, to make way for pasture and cropland is seriously affecting ecosystem services. More effective action is needed to address the problem by implementing conservation measures and drafting territorial management plans that provide for ecological corridors and rehabilitation of degraded pasture. The warning is part of a letter by Brazilian researchers published in the journal Nature [...]Biotech News (Austrália) -
Light Absorption by Molecules Advances Microscopy & Medicine
Publicado em 11 outubro 2023Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength. Measuring the absorbance of an atom or molecule can provide important information about electronic structure, quantum state, sample concentration, phase changes or composition changes, among other variables, including interaction with other molecules and possible technological [...]Mirage News (Austrália) -
New Biomaterial Directly Delivers Meds to Fish Gut
Publicado em 11 outubro 2023A novel biomaterial developed at the Federal University of São Paulo (UNIFESP) in Brazil can help solve two problems at once. As a bioparticle, it can act as a drug carrier, delivering medication directly to the gastrointestinal tract of fish in order to circumvent resistance to conventional antibiotics, for example. In addition, it is administered orally in powder form and is highly palatable to fish, increasing the probability of effective treatment while at the same time reducing the [...]Mirage News (Austrália) -

Thousands of Ancient Structures May Lay Hidden Beneath The Amazon
Publicado em 10 outubro 2023Few places on Earth shape our impression of a pristine environment like the heart of the Amazon. For 6.7 million square kilometers, virtually every patch of soil, every leaf, every pool of water bustles and blooms with a wilderness that defies taming. Yet amid the weave of tree roots and rotting vegetation, hidden by layers of dirt and the chaos of greenery, there is mounting evidence of human influence that dates back thousands of years. In a new study, remote-sensing scientist Vinicius [...]ScienceAlert (Austrália) -
Poor Sleep Quality Exacerbates Health Issues in Obese Elderly: Study
Publicado em 10 outubro 2023Obese older people who sleep badly have less muscle strength and mass in their legs and arms, as well as more body fat and more symptoms of anxiety and depression than those who sleep well, according to a study conducted by researchers at the University of São Paulo (USP) in Brazil. An article on the study is published in the journal Scientific Reports. The number of obese older people has increased worldwide in recent decades. In Brazil, the prevalence of overweight in people aged 60 [...]Mirage News (Austrália) -
Amazon secrets unveiled
Publicado em 06 outubro 2023James Cook University’s Distinguished Professor Bill Laurance, a long-time Amazon expert, took part in the study. He said the Amazon is the world’s most diverse forest and according to the new study may also host more than 10,000 records of pre-Columbian earthworks - constructed prior to the arrival of Europeans. “Anthropologists have debated for decades about whether ancient peoples lived throughout the Amazon Basin, or only along its drier fringes,” said Professor [...]James Cook University (Austrália) -
