Today, sloths are slow-moving, tree-dwelling creatures that live in Central and South America and can grow up to 2.5 feet long . Thousands of years ago, however, some sloths walked along the ground, weighed around 8,000 pounds and were as big as Asian elephants . Some of these now-extinct species were “like grizzly bears, but five times larger,” as Rachel Narducci , collection manager of vertebrate paleontology at the Florida Museum of Natural History, says in a statement In a [...]

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 [...]

Research continues to emerge showing that alcohol is bad for our health, increasing the risk of at least seven different types of cancer, disrupting sleep and hurting mental-wellbeing. Now, scientists have uncovered the exact number of years drinking could cut from your lifespan—and how many drinks per week produce the worst health outcomes. Researchers have found even more reasons to ease up on the alcohol: your lifespan and brain health. Researchers have found even more reasons to [...]

Ultra-processed foods are getting a lot of attention. Research links them to cancer, heart disease, inflammation, cognitive decline, and diabetes. Meanwhile U.S. health secretary Robert F. Kennedy Jr. and his cohort warn against the dangers of foods with more than five ingredients—Kennedy himself has claimed “highly chemically processed foods” are the chief culprit behind an epidemic of chronic disease in the U.S. But new research suggests [...]

A group of researchers has developed a new formulation for the only drug available on the market to treat helminths, as worms such as schistosomes and tapeworms are known. According to the World Health Organization (WHO), 400 million people worldwide suffer from these worms. Praziquantel is sold in large tablets that are difficult to swallow, especially for children and pets such as cats and dogs, which are also colonized by helminths and require preventive treatment. The drug also tastes [...]

Microalgae of the species Monoraphidium contortum have the ability to remove antibiotic residues from water, especially sulfamethoxazole and trimethoprim. This reduces the risk of environmental contamination, avoiding serious consequences for the ecosystem and human health. This was the conclusion of a study conducted in partnership by Brazilian researchers affiliated with the Federal University of ABC (UFABC) in Santo André, the Federal University of Itajubá (UNIFEI) in the [...]

It is impossible to imagine human society without language. For a long time, experts have been trying to understand when language entered the human sphere. Researchers analyzed the various developments that humanity has experienced across the millennium and provided an estimate on when humans garnered the capability of communicating through language, stated IFL Science. Findings regarding this examination have been published in Frontiers in Psychology. The study claims that the genetic [...]

A method using free software and a drone with a low-cost camera has made it possible to select drought-tolerant corn plants. The tool contributes to the selection of plants that can better withstand water stress, one of the impacts of climate change on agriculture. The results of the experiments were published in an article in the Plant Phenome Journal. The authors are associated with the Genomics for Climate Change Research Center (GCCRC), an Engineering Research Center (ERC) at the [...]

High blood pressure (hypertension) causes thickening of the blood vessels and hardening of the arteries (arteriosclerosis). A study conducted by Brazilian researchers has shown for the first time that a similar phenomenon occurs in the lungs. High blood pressure hardens the bronchi and increases airway resistance, impairing respiratory capacity. The study sample comprised 731 men and women over 60, both with and without high blood pressure. It was designed to investigate the effects of [...]
