Mina da Borralha raises doubts about University of Minho investigation: associations demand clarifications

SAPO Notícias10 September 2026 at 16:24

The involvement of researchers and research units from the University of Minho in the Mina da Borralha project is raising doubts and concerns among various associations. These entities demand clarifications about the role played by the academic institution in this process.

The Mina da Borralha, an old mining complex, has become the subject of investigative interest, but the participation of the Minho university in the research is generating controversy. The associations question the transparency and independence of the work developed by the researchers linked to the project.

The associative entities that demand answers do not specify exactly what concrete doubts they raise, but indicate that the investigation conducted by the University of Minho lacks additional explanations about its methodology and conclusions.

The case arises in a broader context of debates about the recovery and enhancement of former mining sites in Portugal, where multiple interests, including environmental and economic ones, frequently conflict.

What is the Equal Earth projection? See the differences compared to the Mercator map

The traditional Mercator world map, created in 1569, distorts the actual size of continents and countries, presenting nations like Greenland and Africa with dimensions that do not correspond to reality. The Equal Earth projection, developed in 2018 by Bojan Šavrič, Bernhard Jenny and Tom Patterson, offers a more faithful alternative by representing the areas of the Earth's surface in the correct proportions, while simultaneously maintaining an appealing visual appearance and the horizontal parallel. This projection shows Europe and North America significantly smaller than they appear on the Mercator map, while Africa and South America appear much closer to their real size.

Low bone volume hinders implants, but there are options available

A 2019 IBGE survey reveals that 34 million Brazilian adults have lost 13 or more teeth, and 14.1 million have no teeth at all. Among elderly people aged 60 or over, nearly one third has lost all teeth. The problem is that without the tooth, the alveolar bone that supported it loses up to 50% of its width in the first year after extraction, making it difficult to place dental implants. However, there are techniques and treatment options available for patients with low bone volume, according to dental implant specialists.

Should you wash rice before cooking it? Here is the answer and the reason few people know

A study published in 2025 in the scientific journal 'Food Chemistry' analyzed whether it is necessary to wash rice before cooking it and found that washing can reduce the concentration of harmful heavy metals, such as cadmium and lead, by up to 50%. The research tested different varieties of rice, including white, brown and basmati, and also evaluated the impact on essential minerals, such as iron. The study used inductively coupled plasma mass spectrometry for a detailed analysis of the multi-element bioaccessibility of long-grain rice, offering a perspective on the risks associated with arsenic and other elements.

Dr. Marco Demange performs MAKO surgery, unprecedented in Brazil

Dr. Marco Demange, orthopedist and associate professor at FMUSP, performed at Hospital Vila Nova Star, in São Paulo, the first unicompartmental knee arthroplasty (UKA) with the MAKO robotic system in Brazil. The procedure marks the arrival in the country of a technology used internationally for 19 years in partial knee surgeries, with more than 240 thousand procedures performed worldwide. The technique is indicated for patients with osteoarthritis located in only one of the knee compartments, allowing specific treatment of the affected region while preserving healthy structures, unlike total prosthesis which replaces the entire joint.
