It is the dry season's silent toll. A new study led by scientists at the University of São Paulo has shown that deforestation is responsible for nearly three-quarters of rainfall decline and 16 percent of temperature rise in the Amazon during this critical period. The research, published in Nature Communications , is the first to untangle the relative impacts of global climate change and local forest loss on the world's largest tropical rainforest. A measurable account of [...]

In Brazil, there is still no advanced therapy product for the treatment of chronic wounds and burns that has been registered with health regulatory bodies. A startup based at the Supera Innovation and Technology Park in Ribeirão Preto, in the interior of the state of São Paulo, intends to break down this barrier and become a pioneer in this segment. The company has developed a 3D-printed biodressing containing human umbilical cord stem cells for the treatment of patients [...]

Dengue fever, caused by a flavivirus named DENV, is a major global health challenge, risking almost half of the world’s population. Since the early 20th century, the scientific community has faced multiple challenges in developing effective dengue vaccines. This spanned a variety of techniques—from the use of ox bile to weaken DENV to the chemical processing of DENV-infected mosquitoes. However, the limitations of these techniques and the urgent need to save millions of people from [...]

Research published in the Journal of Neurochemistry has detailed the role of a protein, hnRNP A1, in the formation and stability of myelin, suggesting an important impact on neurodegenerative diseases and mental disorders such as multiple sclerosis and schizophrenia. The findings pave the way for new research and potential treatments. Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of “insulator.” It [...]

Researchers have utilized the Grüneisen parameter in studying the universe’s expansion, linking thermodynamics with cosmology. Their findings suggest the universe’s continuous cooling is related to its adiabatic expansion, and the potential variability of the cosmological constant challenges traditional models.

The magnetic moment of the muon has posed a scientific puzzle due to the slight difference between its theoretical and experimental values, suggesting interactions with unknown particles or forces. Research involving advanced quantum simulations has started to unravel these discrepancies, offering insights into the fundamental properties of muons and their interactions in particle physics. Credit: SciTechDaily.com The researchers identified the origin of discrepancies in recent predictions [...]

An article published in the journal Catalysis Communications describes a simple, efficient and sustainable approach to the degradation and quantitative monitoring of a mixture of polycyclic aromatic hydrocarbons (PAHs), emerging pollutants that contaminate various ecosystems, owing to oil and other fossil fuel spills and improper disposal of industrial waste. Emerging pollutants are chemical compounds that have recently been identified as harmful to human health and the environment, but are [...]

Dengue, caused by the virus transmitted by the bite of the female Aedes aegypti mosquito and, to a lesser extent, the Aedes albopictus mosquito, is an acute illness characterized mainly by high fever, body aches, and redness of the skin. A small fraction of those displaying symptoms can experience a worsening disease at the end of the first week. These cases, classified as dengue with warning signs and severe dengue by the World Health Organization (WHO), are the most worrying, leading to [...]

A new study examined how artepillin C impacts both healthy and cancerous cells, alongside investigating how changes in the pH of the medium influence its effectiveness. Propolis is a resinous substance collected by bees from tree buds and other botanical sources, used to seal and protect their hives. Known for its antimicrobial properties, propolis has been utilized in traditional medicine to support wound healing, boost the immune system, and treat various ailments. A new study examined [...]
