An Unexpected Chemical May Be the Cause of Red Wine Headaches

Healthcare, Medicine / Samilton Santos

Red wine headaches have been a well-documented phenomenon since Roman times, likely dating back to the origins of winemaking itself, around 10,000 years ago. As chemists focused on winemaking, we set out to uncover the true culprit behind this age-old discomfort. Debunking Common Culprits Over the years, sulfites, biogenic amines, and tannins have been frequently

Study Finds Jupiter’s Volcanic Moon Io Is Not Powered by a Global Magma Ocean

Astronomy, Planetary Science, Science / Samilton Santos

Io, one of Jupiter’s moons, holds the title of the most volcanically active body in the Solar System, boasting around 400 volcanoes and vast lava flows across its surface. However, contrary to earlier theories, a recent study suggests that this volcanic activity is not driven by a global magma ocean beneath its crust. New Study

Parasites Unearthed in 500-Year-Old Toilet Expose Surprising Medieval Disease Networks

Microbiology / Mauro Lucas

The discovery of a 500-year-old African parasite in a Bruges latrine offers new insights into how medieval trade networks facilitated the spread of infectious diseases. Linked to Spanish merchants and global commerce, this finding sheds light on historical health challenges and human migration patterns. Published in Parasitology, the study uncovers one of the earliest known

Expert Identifies Irregular Brain Wave Patterns as Potential Indicator of ADHD

Neuroscience / Mauro Lucas

Children with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue. The Neurological Basis of ADHD The neurological variations in ADHD manifest as

How a Routine Prenatal Test Can Detect Hidden Maternal Cancer

Healthcare, Midwifery / Mauro Lucas

A DNA test designed to screen for fetal abnormalities can sometimes uncover unexpected findings, including hidden cancer in the pregnant individual. A recent analysis revealed that cell-free DNA (cfDNA) screening, commonly used to detect chromosomal disorders, has the potential to identify undiagnosed cancers. Among patients whose cfDNA test results were ambiguous, nearly half were found

This Key Blood Measurement Could Signal Your Future Disease Risk

Healthcare, Medicine / Mauro Lucas

If you’ve ever had a blood test ordered by a doctor, chances are it included a complete blood count (CBC). As one of the most common medical tests worldwide, CBCs are performed billions of times each year to diagnose conditions and monitor overall health. Despite their widespread use, the way clinicians interpret CBC results can

Study Suggests the Sun May Be Due for a Powerful Superflare

Astronomy, Planetary Science / Mauro Lucas

The Sun is far from tranquil. Its surface churns with convection, its magnetic field continuously snaps and reconnects, and it releases energy through violent flares and plasma bursts known as coronal mass ejections (CMEs). Most solar activity poses little threat to Earth, but occasionally, the Sun erupts with a flare so powerful it can cause

Astrophysicists Capture Gamma-Ray Flare Visuals from M87’s Supermassive Black Hole

Astronomy, Astrophysics / Mauro Lucas

In 2019, the Event Horizon Telescope (EHT) unveiled the first image of a black hole, showcasing the supermassive black hole at the center of galaxy M87. Now, this cosmic giant is surprising scientists with an intense teraelectronvolt gamma-ray flare, the strongest observed in over a decade. Emitting photons billions of times more energetic than visible

Researchers Uncover Genetic Changes Associated with Autism and Schizophrenia

Healthcare, Medicine / Mauro Lucas

Copy number variants (CNVs) are genetic changes where segments of chromosomes differ from the usual number of copies. These variations have gained increasing recognition for their role in brain structure and their link to psychiatric disorders. Although CNVs often affect multiple genes, the specific contributions of individual genes within these variants to brain development and
