Researchers at the University of São Paulo (USP) in Brazil have discovered that SARS-CoV-2, the virus responsible for COVID-19, can remain in the sperm of patients for up to 90 days after hospital discharge and up to 110 days after the initial infection. The study, published in the journal Andrology, is the first to demonstrate this prolonged presence of the virus in semen, which can lead to reduced sperm quality. The findings suggest that individuals planning to have children should [...]

Researchers from the University of California, Los Angeles (UCLA) and the Federal University of the ABC (UFABC) in São Bernardo do Campo, São Paulo state (Brazil) have identified a group of neurons deep in the brain that are directly associated with compulsive eating and food craving. The discovery, reported in an article published in Nature Communications, sheds light on the neural mechanisms behind eating disorders and could lead to the development of novel treatment [...]

In 1998, they found something even more surprising: the expansion is speeding up, not slowing down like they thought it would. This led to the idea of [...]

In the fight against cancer, the prevailing approach has been to inhibit the processes that allow cancer cells to divide rapidly. However, this strategy often leads to cancer cells developing workarounds, rendering the tumor unresponsive to treatment. Matheus dos Santos Dias, a researcher, is taking a completely different approach – one that might seem counterintuitive at first. “We’re going against the prevailing view that you can only fight cancer cells by inhibiting [...]

A recent study by Brazilian researchers has found that a nanoemulsion containing particles of curcumin, a substance known for its anti-inflammatory and antioxidant properties, was able to modulate the gut microbiota of mice with intestinal inflammation. The study, supported by FAPESP and published in the International Journal of Pharmaceutics, highlights the potential of curcumin nanoemulsions in preventing and treating inflammatory bowel disease. Curcumin, a yellow polyphenolic pigment [...]

Auricular acupuncture, recommended by the World Health Organization (WHO) and offered as an integrative practice since 2006 by the SUS (Sistema Única de Saúde), Brazil’s national health service, is safe for patients with depression and effectively reduces symptoms of this mental health disorder, according to a study conducted by researchers at the University of São Paulo (USP) and the University of Southern Santa Catarina (UNISUL). The results of the study are [...]

In 2021, a female White-eared opossum was found dead in a São Paulo, Brazil park. According to researchers, the opossum died from rabies meningoencephalitis. Reported in an article published in the journal Emerging Infectious Diseases, the finding serves as an alert to the presence of the virus, which is deadly to humans, in the urban environment. “Dog rabies is no longer present in São Paulo state, thanks to the success of vaccination campaigns for domestic animals. [...]

Researchers from University of California San Diego, as part of a large collaboration with scientists around the world, have developed a new search tool to help researchers better understand the metabolism of microorganisms. Microbes are key players in virtually all biological and environmental systems, yet limitations in current techniques used to study microbial metabolism make it difficult to decode their interactions and activities. The new research, published February 5, 2023 in Nature [...]
