For more than 100 years, scientists have pursued the idea of insulin in pill form, often described as a “dream” treatment for diabetes. The challenge has been the body itself. Enzymes in the digestive system break down insulin before it can work, and the intestine lacks a natural way to…
As quantum computers grow more powerful, many current encryption methods could eventually become vulnerable. One promising solution is quantum cryptography, which relies on the laws of physics rather than mathematical complexity to keep data secure. However, making quantum communication practical requires small, dependable devices that can accurately read delicate quantum…
Atomically thin semiconductors like tungsten disulfide (WS2) are emerging as key materials for next-generation photonic technologies. Even though they are only a single layer of atoms, they can host tightly bound excitons, which are electron and hole pairs that interact strongly with light. These materials can also produce new colors…
Researchers at Tokyo Metropolitan University have uncovered the real reason liquid drains from foams, resolving a long-standing scientific puzzle. Traditional physics models have consistently overestimated how tall a foam must be before liquid begins to leak out. By closely observing foam behavior, the team found that the key factor is…
University of Georgia researchers have identified and formally described two previously unrecognized species of black bass, known as Bartram’s bass and Altamaha bass, in a recently published study. Although the species are only now being officially classified, they have been seen before. Ecologist Bud Freeman first came across Micropterus pucpuggy,…
Researchers from the University of St Andrews have documented sperm whales striking each other with their heads, capturing the behavior on video and formally describing it for the first time. The finding supports stories from 19th-century sailors who reported whales using their heads to ram and push objects, sometimes even…
A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian has achieved a first by using galactic archaeology to uncover the past of a galaxy beyond the Milky Way. This method examines detailed chemical signatures in space to reveal how galaxies form and evolve over time.…
Low back pain (LBP) is one of the most widespread health issues globally, affecting people across all age groups and putting significant strain on healthcare systems. For many, the pain becomes long-lasting, disrupting work, sleep, and everyday life. In most cases, however, doctors cannot pinpoint a clear structural cause, which…
A Mayo Clinic-led study reports that postmenopausal women using menopausal hormone therapy experienced significantly greater weight loss when taking tirzepatide, a Food and Drug Administration-approved medication for overweight and obesity. On average, these women lost about 35% more weight compared to those using tirzepatide alone. The results, published in The…
Teeth can lose their brightness over time, even with consistent brushing. Staining can come from genetics or from everyday foods and drinks like coffee and tomatoes. While chemical whitening products are widely used, they can sometimes harm tooth enamel. To address this, researchers reporting in ACS Nano have created an…
A team led by neurobiologist Prof. Dr. Hilmar Bading at Heidelberg University has identified a key molecular process that drives the progression of Alzheimer’s disease. Working with researchers from Shandong University (China), the scientists used a mouse model of Alzheimer’s to show that a harmful protein interaction causes brain cells…
A new study offers fresh insight into how people judge the environmental impact of the foods they eat, and the results suggest many are getting it wrong. These misunderstandings point to a clear need for simple environmental impact labels to help guide better choices. Researchers from the University of Nottingham’s…
Microplastics and nanoplastics are widely known for contaminating oceans, rivers, and farmland. New research now shows they are also accumulating in forests. Geoscientists at TU Darmstadt report this finding in a study published in Nature Communications Earth & Environment, highlighting a largely overlooked form of environmental pollution. The study reveals…

Researchers supported by the National Institutes of Health (NIH) have created a new blood test designed to identify pancreatic ductal adenocarcinoma, one of the most lethal types of cancer. Because pancreatic cancer is often discovered only after it has advanced, treatment options are limited and survival rates remain low. This…
Scientists have uncovered a surprising risk linked to blocking a cellular enzyme once believed to protect against fatty liver disease. Instead of helping long term, shutting down this enzyme may raise the chances of chronic liver damage and cancer as people age. In a study published in Science Advances, researchers…
Researchers have identified a specific part of the brain that may play a key role in high blood pressure. This area, called the lateral parafacial region, is located in the brainstem, the oldest part of the brain responsible for automatic functions like breathing, digestion, and heart rate. “The lateral parafacial…
Australian researchers have taken an important step forward in energy storage, successfully developing and testing what is believed to be the world’s first proof-of-concept quantum battery. Scientists say this emerging technology could reshape how energy is stored and delivered, potentially enabling devices to charge at dramatically faster speeds. First Quantum…
Superconductors are materials that allow electricity to flow without resistance, typically only at extremely low temperatures. While most follow well-understood physical rules, strontium ruthenate, Sr2RuO4, has remained difficult to explain since its superconducting behavior was first identified in 1994. It is one of the most precisely studied unconventional superconductors, yet…
Time crystals are unusual forms of matter made up of particles that “tick,” meaning they move back and forth in steady, repeating cycles. Scientists first predicted their existence and later confirmed them about a decade ago. Although practical uses have not yet been developed, these systems are considered promising for…
GLP-1 medications, such as semaglutide (Ozempic, Wegovy, and Rybelsus), commonly prescribed for diabetes and obesity may also be linked to better mental health outcomes, according to new research.
