Resistance training and physical exercise plays a role in alleviating symptoms of Alzheimer's disease, researchers suggest.  An article published in the journal Frontiers in Neuroscience said its beneficial effects serve as a "complementary treatment." The work's Brazilian authors from the Federal University of São Paulo and the University of São Paulo conducted experiments with transgenic mice with a mutation responsible for [...]

Dinosaurs weren’t always that big – some were barely the size of dogs. So how did they get so ginormous? Scientists have found the missing link – air sacs that made their bones less dense, allowing them to grow to more than 30 metres in length. That’s equal to the size of two buses put together. According to a recent study, these air sacs – or bone cavities – which are typical in present-day birds, enabled dinosaurs to capture more oxygen, keep [...]

A man has seen his cancer disappear after just one month of cutting-edge treatment. Brazilian Paulo Peregrino, 61, was told that there was no chance of his cancer improving prior to undergoing the innovative treatment in April. But on Sunday, Peregrino was discharged from the Hospital das Clínicas of the Faculty of Medicine at the University of São Paulo (USP) in Brazil, Radioagência Nacional reported. The 61-year-old had received CAR-T cell therapy—one of [...]

There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil. So geologist Fernanda Avelar Santos was startled to find an unsettling sign of human impact on the otherwise untouched landscape: rocks formed from the glut of plastic pollution floating in the ocean. Santos first found the plastic rocks in 2019, when she traveled to the island to research her doctoral thesis on a completely different topic -- [...]

The geology of Brazil’s volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm. Melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans’ growing influence over the earth’s geological cycles. “This is new and terrifying at the same [...]

TRINDADE ISLAND, Brazil, March 15 (Reuters) - The geology of Brazil's volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm.

(Reuters) -- La geología de la isla volcánica brasileña de Trindade lleva años fascinando a los científicos, pero el descubrimiento de rocas formadas por restos de plástico en este remoto refugio de tortugas está desatando la alarma. El plástico fundido se ha entremezclado con las rocas de la isla, situada a 1.140 kilómetros del sudoriental estado de Espirito Santo, lo que, según los investigadores, evidencia la creciente [...]

People who are experiencing anxiety and depression months after a mild case of COVID-19 may have changes affecting the structure and function of their brains, Brazilian researchers report. "There is still much to learn about long COVID, which includes a wide range of health problems, including anxiety and depression, months after infection," said Dr. Clarissa Yasuda of the University of Campinas in São Paulo. "Our findings are concerning, as even [...]
