Brazil has emerged as a pioneering force in transforming gold supply chain transparency through comprehensive regulatory reform and technological innovation. The Brazil gold supply chain initiative, launched through the Brazilian Forum for Responsible Gold in September 2025 at the Ministry of Mines and Energy in Brasília, represents an unprecedented collaboration between government agencies, international organisations, and industry stakeholders committed to combating illegal mining [...]

In a groundbreaking discovery, scientists have uncovered one of the oldest and longest-lasting collections of stone tools ever found—evidence that early humans had already mastered technology nearly 2.75 million years ago. The tools, discovered at the Namorotukunan Site in Kenya’s Turkana Basin, show that our ancient ancestors were remarkably skilled and adaptable, even as they faced dramatic environmental upheavals. The study, published in Nature Communications, describes how [...]

Living with constant pain can wear down both body and mind. For women suffering from temporomandibular disorder (TMD)—a condition that affects the jaw joint and chewing muscles—everyday life can be a challenge. The disorder often causes persistent pain in the jaw, temples, face, or ears, along with headaches and difficulty chewing. Now, new research from the University of São Paulo (USP) in Brazil shows that practicing mindfulness meditation can help women with TMD [...]

Mental health disorders such as depression, anxiety, and ADHD affect millions worldwide and contribute significantly to the global burden of disease—impacting individuals' health and daily lives and placing a substantial strain on social systems and national and global economies. These conditions often involve differences in brain development, particularly during childhood and adolescence. However, tracking these brain changes in relation to psychopathology—the study of [...]

The very first humans millions of years ago may have been inventors, according to a discovery in northwest Kenya. Researchers have found that the primitive humans who lived 2.75 million years ago at an archaeological site called Namorotukunan used stone tools continuously for 300,000 years. Evidence previously suggested that early human tool use was sporadic: randomly developed and quickly forgotten. The Namorotukunan find is the first to show that the technology was passed down [...]

WASHINGTON (Nov. 4, 2025)--Imagine early humans meticulously crafting stone tools for nearly 300,000 years, all while contending with recurring wildfires, droughts, and dramatic environmental shifts. A recent study, published in Nature Communications, brought to light remarkable evidence of enduring technological tradition from Kenya's Turkana Basin. An international multi-center research team has uncovered at the Namorotukunan Site one of the oldest and longest intervals of early [...]

Living with chronic pain on a daily basis impacts not only the body but also the mind and emotions. This is the reality for thousands of people with temporomandibular disorder (TMD), a condition affecting the joint responsible for opening and closing the mouth, as well as the chewing muscles. For these individuals, constant jaw, temple, facial, or ear pain; difficulty chewing; and headaches can affect their daily routine and mental health. A study conducted at the Ribeirão Preto [...]

A simple imaging exam capable of assessing myocardial deformation during contraction has emerged as a promising tool for predicting the risk of cardiac complications in patients with chronic Chagas disease. The study, conducted by researchers at the University of São Paulo (USP) in Ribeirão Preto in partnership with researchers from Duke University and Yale (both in the United States), highlights the global longitudinal strain (GLS) index – already used in other diseases and [...]

Brazilian scientists have created a low-cost, portable sensor that can quickly detect a brain protein linked to mental health conditions like depression, schizophrenia, and bipolar disorder.   This new tool may help doctors find and treat these problems earlier, which could lead to better care for patients. The sensor was made through a partnership between the University of São Paulo (USP) and Embrapa Instrumentação, a division of the Brazilian Agricultural Research Corporation. It [...]
