Poor sleep can affect almost every part of the body, including the hormones that keep us healthy. Researchers are increasingly finding that sleep disorders and hormone disorders often occur together. A new Brazilian study suggests that one of the strongest links may be between hypothyroidism and obstructive sleep apnea. Hypothyroidism develops when the thyroid gland in the neck produces too little thyroid hormone. These hormones help regulate how the body uses energy and influence many [...]

The more we find out about ultra-processed foods, the more we lose our appetite. These industrially formulated food products are low in nutrients and high in all kinds of dubious additives, and they're increasingly taking over the modern diet. That's a problem, because scientists keep uncovering new evidence of the health issues posed by ultra-processed foods, which have been linked to cancer, neurodegenerative diseases, and much more. But the risks of ultra-processed food [...]

A combination of omega-3 and low-dose acetylsalicylic acid (ASA) produced results comparable to antibiotics in treating severe periodontitis. This conclusion is based on a study conducted by researchers affiliated with Albert Einstein Israelite Hospital, Guarulhos University (UNG), the University of Taubaté (UNITAU), and the Ribeirão Preto School of Dentistry at USP (FORP-USP) in Brazil, as well as Harvard University in the United States. The findings were published in May in the Journal of [...]

Millions of people around the world live with hypothyroidism, a condition in which the thyroid gland does not produce enough hormones. These hormones help control metabolism, body temperature, heart rate, and many other important body functions. When hormone levels fall, people often feel tired, gain weight, have dry skin, feel cold, and struggle to concentrate. Another common health problem is obstructive sleep apnea, or OSA. This condition causes the airway to become blocked many times [...]

Are some interventions designed to induce gratitude more effective than others? In which countries and cultures do they work best to improve mood, strengthen bonds between people, and promote social reciprocity? A study aimed at answering these questions – conducted in 34 countries with over 10,000 participants – had its results published in May in the scientific journal PNAS. In Brazil, the project received the help of researchers and 598 volunteers who responded to intervention prompts [...]

Marcos Vinicius Sampaio Vieira, a 56-year-old Brazilian engineer, spent a month in Italy to say goodbye to his older brother, who died in June from intestinal cancer. This loss reignited an untold story spanning generations of the Vieira family, which had only begun to be investigated 21 years earlier when Marcos, at age 35, discovered three nodules in his thyroid during a routine visit to a cardiologist – one of them measuring four centimeters. "I was referred to an endocrinologist, and [...]

Polystyrene production is growing rapidly each year, with market research suggesting it could reach some 62 million tons by 2034. We're yet to find a good way to recycle the stuff, so most polystyrene currently ends up in landfills. Scientists have been looking to nature for solutions. So far, they've found plenty of insects that appear capable of munching away at our plastic problem, though it's unclear exactly what happens to the plastic or how these grubs are breaking it [...]

An international team of researchers has developed an innovative strategy for producing new vaccines. They created a genetically modified version of the Chikungunya virus that replicates only once, yet still trains the immune system to defend itself without causing disease. In tests conducted on mice, a single dose of the formulation containing the modified immature virus was sufficient to generate antibodies and protect the rodents against lethal infection. The study was published in [...]
