Tiny Micro-Flower Could Revolutionize Drug Delivery Inside the Body

Medications, whether taken orally or intravenously, often spread throughout the body instead of targeting the specific area where they are needed. However, this inefficiency may soon be addressed by a new microparticle design resembling a flower. In recent years, researchers have developed various particles for targeted drug delivery. These microscopic particles are typically loaded with […]

Astronomy, Planetary Science / Samilton Santos

One of the most peculiar galaxies near the Milky Way has presented astronomers with a new and intriguing mystery Known as Centaurus A, this galaxy hosts a supermassive black hole at its center that emits enormous jets of plasma. These jets, traveling through intergalactic space, have collided with something mysterious. But what is this “something“?

Unusual Particle Gains or Loses Mass Depending on Its Direction of Movement

Physics / Samilton Santos

Scientists have accidentally discovered a particle that has mass when moving in one direction but lacks mass when traveling in another. Known as semi-Dirac fermions, these particles with peculiar behavior were first theorized 16 years ago. A new phenomenon observed in ZrSiS material Researchers discovered the phenomenon in a semimetal material called ZrSiS, which consists

Blood-Derived Living Material Offers New Hope for Bone Repair, Study Finds

Healthcare, Medicine / Mauro Lucas

When skin is injured, blood clots naturally initiate the healing process. Building on this mechanism, scientists have created a blood-based implant that accelerates and enhances tissue repair, particularly for broken bones. The research team describes this innovation as a “biocooperative regenerative” material. By incorporating synthetic peptides, the implant strengthens the blood clot’s natural barrier to

First-Time Cocaine Use in Rats Highlights Individual Susceptibility to Addiction

Basic Research, Uncategorized / Mauro Lucas

Researchers at the University of Texas at El Paso (UTEP) explored how rats react to cocaine paired with an unpleasant stimulus, uncovering new insights into addiction vulnerability. In the experiment, nearly 30 rats self-administered intravenous doses of cocaine hydrochloride combined with quinine—a bitter but safe compound—via a nose-poke mechanism. The quinine hit preceded the cocaine

Drinking Cocoa May Help Shield Your Body From Fatty Foods and Stress

Basic Research / Mauro Lucas

Stress often drives us to indulge in foods that aren’t healthy, but scientists have found a surprising way to counteract the negative effects: pairing high-fat meals with antioxidant-rich cocoa. Stress, even in short bursts, can temporarily harm arterial function. Eating fatty foods may feel comforting but can worsen cardiovascular stress, delaying recovery. However, there’s good

Tinnitus Appears to Be Connected to an Essential Bodily Function

Healthcare / Mauro Lucas

Around 15% of people worldwide experience tinnitus, a condition causing phantom sounds like ringing or buzzing without any external source. Often linked to hearing loss, tinnitus can significantly affect mental health, leading to stress or depression, especially in long-term cases. With no cure available, better management or treatment could benefit millions. Sleep may offer insights

Adults Generate New Brain Cells, Which Play a Role in Enhancing Learning Through Listening

Neuroscience, Science / Mauro Lucas

Your brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function? Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether adult

Hidden Fat Can Predict Alzheimer’s Up to 20 Years Before Symptoms Appear

Healthcare, Medicine / Mauro Lucas

Researchers have linked a specific type of body fat to the buildup of abnormal brain proteins—hallmarks of Alzheimer’s disease—up to 20 years before the earliest symptoms of dementia appear. This finding, presented at the annual meeting of the Radiological Society of North America (RSNA), highlights the potential for lifestyle changes targeting visceral fat to influence
