Scientists are looking at ways to tackle Alzheimer's and dementia from all kinds of angles, and a new study has identified the molecule hevin (or SPARCL-1) as a potential way of preventing cognitive decline. Hevin is a protein naturally produced in the brain by cells called astrocytes. These support-worker cells look after the connections or synapses between neurons, and it's thought that hevin plays a role in this essential work. In this new study, researchers from the Federal [...]

Maintaining muscle mass has proven to be crucial for patients undergoing cancer treatment. Studies have shown that individuals with more muscle tend to respond better to therapies such as chemotherapy and radiotherapy. They also have a lower risk of complications and experience more effective recovery. This is because muscle plays an essential role in metabolism, helping to regulate the inflammatory response and drug absorption. Conversely, cancer patients with low muscle mass have a higher [...]

A study conducted by researchers from the Federal University of São Carlos (UFSCar) found that 72.5% of young Brazilian women suffer from symptoms such as itching, discharge, and pain during intercourse. The study, which included 313 volunteers in their 30s, showed that, although these symptoms negatively affect quality of life and sexual health, they have largely been normalized. The data were published in the Brazilian Journal of Physical Therapy. According to Ana [...]

Twenty years ago, the US Congress instructed NASA to find 90 percent of near-Earth asteroids threatening Earth. They've made progress finding these asteroids that orbit the Sun and come to within 1.3 astronomical units of Earth. However, they may have to expand their search since astronomers are now finding asteroids co-orbiting Venus that could pose a threat. New research tries to understand how many more may co-orbit Venus and how we can detect them. They can be hidden in the [...]

Perovskite solar cells are a new type of solar technology that’s lightweight, flexible, and affordable. They can be used in creative ways, like in windows, clothing, or tents that generate electricity from the sun. But despite their promise, these solar cells haven’t made it to everyday use just yet—mainly because they don’t last long. Exposure to humidity and everyday temperatures causes the materials in the cells to break down quickly, making them unreliable over [...]

Story at-a-glance A study from Brazil's State University of Campinas found twice-weekly weight training for six months preserved brain regions vulnerable to Alzheimer's in older adults with mild cognitive impairment In this research, five of the 22 people in the resistance training group improved enough to no longer meet clinical criteria for cognitive impairment Exercise protects the brain through multiple mechanisms. It stimulates growth factors like BDNF, reduces [...]

Diamond is one of the most prized materials in advanced technologies due to its unmatched hardness, ability to conduct heat and capacity to host quantum-friendly defects. The same qualities that make diamond useful also make it difficult to process. Engineers and researchers who work with diamond for quantum sensors, power electronics or thermal management technologies need it in ultrathin, ultrasmooth layers. But traditional techniques, like laser cutting and polishing, often damage the [...]

Despite being considered sanctuaries for biodiversity, Brazil's marine protected areas (MPAs) are not immune to microplastic contamination. A recent study has shown that even MPAs classified as integral protection areas (APIs), which are the most restrictive to human intervention, are contaminated by this material. The research, which involved Brazilian and Australian scientists, used bivalve mollusks (oysters and mussels) as sentinel organisms to assess contamination. The results [...]
