Sweet but risky? Stevia has been linked with brain stroke
Artificial sweeteners have been seen as a safer alternative to sugar for years, low-calorie, diabetes-friendly, and tooth-friendly too. Among them, Stevia and Erythritol often come up together in sugar-free products. But a recent study has shaken things up, linking erythritol, a sweetener blended with Stevia in commercial products, to potential risks that could affect the brain's vascular system. The word "stroke" instantly grabs attention, and rightly so. But it's important to understand the reasoning behind it. What did scientists really do? This study was conducted in vitro, meaning it was done outside the human body, specifically in a lab, using cultured human brain microvascular endothelial cells (hCMECs). These are the same types of cells that line blood vessels in the brain and help regulate things like blood flow and clotting. Researchers treated these cells with erythritol in quantities equivalent to what's found in a standard artificially sweetened drink (around 30g of erythritol). The goal? To observe how this sweetener affects oxidative stress, nitric oxide (NO) production, and markers that influence blood clotting and vessel function. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo Spike in oxidative stress One of the most striking findings was a significant increase in reactive oxygen species (ROS), basically, unstable molecules that can cause oxidative stress, damaging cells over time. The oxidative stress levels were double in erythritol-treated cells compared to untreated ones. This triggered the cells to produce more antioxidant proteins like superoxide dismutase-1 and catalase, which act like emergency fire extinguishers in the body. But if the fire is too strong, even more antioxidants might not be enough. The takeaway? This oxidative imbalance may weaken the blood-brain barrier over time, possibly contributing to neurovascular issues like stroke. Why blood flow suffers Nitric oxide (NO) is crucial, it helps relax blood vessels, ensuring smooth blood flow. The study found that NO production dropped in erythritol-treated brain cells, even though the main enzyme that produces it (eNOS) didn't change much. The twist? The phosphorylated forms of eNOS (the active and inactive switches) were altered, one became less active, the other more inhibitory. This disrupted signaling means the vessels may not relax properly, increasing the risk of clot formation or vascular stiffness, both red flags for ischemic stroke.

Exoplanet 35 Light-Years Away Offers Hope for Life Beyond Earth
A team of scientists has studied the L 98-59 planetary system and confirmed the existence of a fifth planet, named L 98-59 f, in the star's habitable zone. The zone has conditions that could allow liquid water to exist. L 98-59 is a small red dwarf located just 35 light-years from Earth. In 2019, NASA's TESS space telescope found that it hosts three small transiting exoplanets. A fourth planet was revealed through radial velocity measurements with the European Southern Observatory's ESPRESSO spectrograph. Now, the team led by the Trottier Institute for Research on Exoplanets (IREx) at the Universite de Montreal has found a fifth one in the system. "These new results paint the most complete picture we've ever had of the fascinating L 98-59 system," said Cadieux in the press release. "It's a powerful demonstration of what we can achieve by combining data from space telescopes and high-precision instruments on Earth, and it gives us key targets for future atmospheric studies with the James Webb Space Telescope [JWST]." The exoplanet has a minimum mass 2.8 times that of Earth and has been categorised as a super-Earth. L 98-59 f follows an almost perfectly circular orbit around its star, receiving roughly the same amount of stellar energy as Earth. Its location in the habitable zone suggests that liquid water could exist on its surface under suitable atmospheric conditions, making it a potential candidate to support life. If L 98-59 f has an atmosphere, telescopes like the James Webb Space Telescope (JWST) may be able to detect water vapour, carbon dioxide or even biosignatures. Cadieux said that the discovery highlights the "diversity of exoplanetary systems" and also "strengthens the case for studying potentially habitable worlds around low-mass stars". "With its diversity of rocky worlds and range of planetary compositions, L 98-59 offers a unique laboratory to address some of the field's most pressing questions: What are super-Earths and sub-Neptunes made of? Do planets form differently around small stars? Can rocky planets around red dwarfs retain atmospheres over time?" René Doyon, co-author of the study, who is a professor at UdeM and the Director of IREx, said. The findings are reported in research that will appear in The Astronomical Journal titled "Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone."
