Rapid side-to-side eye movements can help stabilize posture, avoid falls and maintain balance for people with Parkinson's disease, just as they can for healthy people. This seemingly counterintuitive conclusion was reached by researchers at São Paulo State University (UNESP) in Brazil and the University of Lille in France in a study supported by FAPESP. An article on the study is published in the journal Biomechanics. Ten individuals diagnosed with Parkinson's and 11 [...]

Using sequencing techniques, researchers associated 51 mutations in mitochondrial DNA with amyotrophic lateral sclerosis (ALS), an incurable degenerative neurological disorder that leads to muscle atrophy and paralysis. Thirteen of the mutations increased the risk of ALS, while 38 were protective. The study suggests these mutations may be important for future tests and research on ALS. An article on the study is published in the journal Muscle & Nerve. It is worth recalling that [...]

Eye 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 [...]

A study of patients with metastatic lung cancer by researchers based in Brazil and the United States has found that their performance in simple physical tests such as sitting down, standing, and walking can help physicians arrive at a prognosis and approach to treatment. The European Journal of Clinical Investigation published an article on the study. The findings also included identity fiction in the volunteers’ blood plasma of two substances—ser and M22G—wit—with [...]

Researchers have discovered a new species of flea toad in which one of the adults measured just 6.95mm in length – the second smallest adult vertebrate ever described. Vertebrates are animals with a spine, which includes all fish, amphibians, reptiles, birds, and mammals. But this new flea toad, Brachycephalus dacnis, which was found in the Atlantic Rainforest in Ubatuba on the coast of Brazil, is tiny. Only one related species of the genus is known to be smaller. “There [...]

Flea toads, as some species in the genus Brachycephalus are known, are less than 1 cm long in adulthood. Its size is far smaller than a fingernail or a 50 cent (50p) coin. The name of the new species, B. dacnis, pays tribute to Project Dacnis, a conservation, research and education NGO that maintains private areas of Atlantic Rainforest, including the one where the animal was found, in Ubatuba, on the coast of São Paulo state. "There are small toads with all the [...]

They headed toward the noise, but as they got closer and closer, the sound stopped. The song belonged to a “miniaturized” animal hidden under the leaves , according to a study published Oct. 25 in the peer-reviewed journal PeerJ. Researchers collected a dozen of the creatures during field surveys between June 2021 and May 2022 and took a closer look at the unfamiliar amphibians. With a gaping mouth and body smaller than a fingernail, the “toadlet” has now been [...]
