Scientists develop low-cost method to remove microplastics from water
Publicado em 17 novembro 2024
Microplastics, tiny plastic particles, are found almost everywhere—in the air, soil, oceans, and even inside our bodies.
These fragments, created by the breakdown of larger plastic items or from synthetic fibers in clothing, are a growing environmental problem.
Even smaller nanoplastics, which are invisible to the naked eye, are even more dangerous.
They can pass through biological barriers and harm vital organs. Scientists recently found nanoplastics in the human brain, raising [...]

New light therapy offers hope for diabetic nerve pain relief
Publicado em 15 novembro 2024A recent study from the Federal University of São Paulo (UNIFESP) has found that using infrared light along with regular physical therapy could be a new way to relieve nerve pain in people with diabetes. This type of nerve damage, called peripheral diabetic neuropathy, often affects the legs and feet. It’s a common and painful complication for people with diabetes, often worsening over time if blood sugar isn’t well-controlled. Nerve pain from diabetic neuropathy [...]ver notícia -
High blood sugar increases blood clot risks in diabetics
Publicado em 08 novembro 2024A recent study by scientists at the Center for Research on Redox Processes in Biomedicine (Redoxoma) has shed light on why people with high blood sugar, often due to diabetes, are more likely to suffer from blood clots, a condition known as thrombosis. These findings, published in the Journal of Thrombosis and Haemostasis, could help develop new ways to protect diabetics from heart attacks and strokes. Thrombosis plays a major role in severe health issues like heart attacks and strokes, [...]ver notícia -
This type of eye movement can improve balance in Parkinson’s disease
Publicado em 01 novembro 2024Eye movements that shift quickly from one side to another can help people with Parkinson’s disease keep their balance, much like they do for healthy individuals. While this might seem unexpected, researchers from São Paulo State University (UNESP) in Brazil and the University of Lille in France found this surprising link in a recent study. The study included ten people with Parkinson’s disease and eleven healthy people, all over 60 years old. Each participant had to [...]ver notícia -
How dinosaurs’ extinction helped ants become farmers
Publicado em 08 outubro 2024When a huge asteroid hit Earth 66 million years ago, it wiped out the dinosaurs and drastically changed the planet. While the disaster caused plants and animals to die in massive numbers, it also created a new opportunity for ants to become some of the earliest farmers on Earth, millions of years before humans. The asteroid impact led to a low-light environment where fungi, which feed on dead plants and animals, could thrive. These conditions were perfect for a group of ants [...]ver notícia -
Can vegans get enough protein?
Publicado em 30 setembro 2024Study finds plant-based diets are adequate but often rely on processed products. A recent study from the University of São Paulo has found that vegans generally consume enough protein and essential amino acids through their diets, but some rely on processed foods like protein supplements to meet their needs. This research, published in JAMA Network Open, involved 774 men and women who follow a vegan diet. The study revealed that the participants mainly ate unprocessed or [...]ver notícia -
Fasting may increase cancer risk, MIT study finds
Publicado em 25 agosto 2024Fasting and low-calorie diets have been praised for their potential health benefits, including delaying age-related diseases and extending lifespan. However, a recent study by MIT researchers reveals that while fasting can help the gut heal, it might also increase the risk of developing cancer under certain conditions. The study, conducted on mice, shows that fasting boosts the ability of intestinal stem cells to regenerate, helping the intestine recover from injuries or [...]ver notícia -
Scientists find mild COVID-19 can cause long-term memory and attention issues
Publicado em 29 julho 2024Even mild cases of COVID-19 can lead to long-term cognitive problems, including memory loss and attention deficit, according to a study by researchers at the University of São Paulo (USP) in Brazil. The study, published in the journal BMC Psychology, emphasizes the need for comprehensive rehabilitation to address these lasting cognitive impacts. The study involved 302 volunteers and found cognitive impairment in 11.7% of those with mild COVID-19, 39.2% with moderate cases, and [...]ver notícia -
COVID-19 virus found in sperm for over three months: what you need to know
Publicado em 05 junho 2024Researchers from the University of São Paulo (USP) in Brazil have discovered that the virus causing COVID-19, SARS-CoV-2, can stay in the sperm of patients for up to 110 days after initial infection. This groundbreaking study, published in the journal Andrology, suggests that people planning to have children should wait for a period after recovering from COVID-19. The study revealed that the virus, known to invade and destroy various human cells, including those in the reproductive [...]ver notícia -
Ancient Peru crisis linked to violence, study shows
Publicado emDuring the transition from the fifth to the fourth century BCE, the Central Andes, an area now part of Peru, experienced a period of significant change and turmoil. Researchers delving into this era have unearthed evidence suggesting that this time was marked by political upheaval and violence, potentially linked to a shift away from religiously driven governance towards more secular forms of leadership. A groundbreaking study published in Latin American Antiquity by an international [...]ver notícia
