Scientists Develop Contact Lenses that Offer Enhanced Vision

Healthcare, Medicine /

Chinese researchers have created a contact lens designed to give humans a form of “super vision”—the ability to perceive infrared light, which is normally invisible to the naked eye. The breakthrough relies on upconversion nanoparticles, which absorb infrared light and convert it into visible light, effectively extending human vision beyond its natural 400–700 nanometer range. […]

Researchers Create a 3D Embryo Model that Makes Blood Cells

Healthcare, Medicine /

A group of UK scientists has developed a 3D embryo model that reproduces certain aspects of early human development, including blood cell formation, EFE reported Monday. “Our model recreates the process of human fetal blood development—the blood that circulates in a baby during pregnancy—within the lab,” explained a cell biologist from the Gurdon Institute at

How Does Eating Too Many Ultra-Processed Foods Affect your Body?

Healthcare, Medicine /

Ultra-processed foods (UPFs) — like sodas, snacks, and processed meats — are heavily altered, additive-filled products low in nutrients. They now account for nearly 60% of adults’ and almost 70% of children’s diets in the U.S. Designed to last longer and be more appealing, UPFs reduce overall nutritional quality and often lead to overeating. In

Debate Over Apple Cider Vinegar Casts Doubt On its Weight-Loss Benefits

Healthcare, Medicine /

The authors, the wellness industry, and the journal publisher BMJ Group have been set back after they retracted a widely publicized study that helped fuel the rise of the apple cider vinegar (ACV) trend. Researchers found that the study, which suggested that consuming one to two teaspoons of ACV daily could lead to significant weight

What We Know and Don’t About Painkillers and Autism

Healthcare, Medicine /

There is limited scientific evidence backing the U.S. government’s recent decisions to issue warnings about the use of a common painkiller during pregnancy and to expedite approval of an experimental drug for autism. On Monday, the U.S. government revealed two autism-related measures. First, it plans to update warning labels on the widely used painkiller paracetamol

Research Uncovers Brain Mechanism That Heals the Body During Sleep

Healthcare, Medicine /

During sleep, the body releases ‘growth hormone‘ to repair and strengthen muscles and bones — though the exact mechanisms behind this process have long been unclear. Now, through detailed analysis of brain circuits in mice, a research team led by scientists at the University of California, Berkeley (UC Berkeley) has uncovered specific mechanisms and feedback

Ozempic Rival? New Therapy Reprograms Metabolism for Sustainable Weight Loss

Healthcare, Medicine /

Although medications like Ozempic have shown strong results in helping people shed pounds, many patients regain the weight once they stop treatment. A new drug, however, takes a different approach, aiming to deliver longer-lasting results by altering the body’s metabolism. Drugs such as Ozempic, Wegovy, and Trulicity belong to a class called GLP-1 receptor agonists.

UFRJ Researchers Develop Drug to Reverse Spinal Cord Damage

Healthcare, Medicine /

A 25-year UFRJ study developed polylaminin, a placenta-derived drug that shows promise in regenerating spinal cords. The research, led by Professor Tatiana Coelho de Sampaio, head of the Extracellular Matrix Biology Laboratory at UFRJ’s Institute of Biomedical Sciences, showed that some patients regained partial or full movement after treatment. Polylaminin works by rejuvenating mature neurons
