Nearly every animal species, including humans, has blood cells. But blood is not the same across the animal kingdom. Different species have evolved different types of blood and immune cells, reflecting millions of years of adaptation against infection and disease. Scientists already understand a great deal about the makeup and…
We’ve all heard the advice: eat your fruit and vegetables, get your vitamins, and stay healthy. For the most part, that guidance holds up. But some nutrients have a more complicated story, and vitamin B12 is a fascinating example. Also known as cobalamin, B12 is essential for life. It helps…
Diseases such as Alzheimer’s, Parkinson’s, and Huntington’s slowly damage the brain by destroying neurons, the cells that carry messages through the nervous system. As these cells are lost, people can experience memory problems, cognitive decline, and movement difficulties that often become severe enough to require constant care. Current medicines can…
Researchers at Texas A&M University say they may have found a way to do just that using a simple nasal spray designed to reduce inflammation in the brain. In a new study, scientists reported that the treatment restored memory, reduced chronic inflammation, and improved brain cell function after just two…
Recent findings from research we have been carrying out at the Large Hadron Collider (LHC) at Cern in Geneva suggest that we might be closing in on signs of undiscovered physics. If confirmed, these hints would overturn the theory, called the Standard Model, that has dominated particle physics for 50…
NASA’s Psyche spacecraft has successfully completed a close flyby of Mars, using the planet’s gravity to gain speed and redirect its path toward the asteroid Psyche. On May 15, the spacecraft passed within 2,864 miles (4,609 kilometers) of the Martian surface, receiving a crucial gravitational assist without using additional onboard…
About 4.6 billion years ago, the young Sun was surrounded by a massive disk of gas and dust. Over time, tiny dust grains collided and stuck together, eventually forming larger rocky bodies called planetesimals, the building blocks of planets and asteroids. But scientists believe this process was far from simple.…
Magnetic fields are found everywhere in the universe, from planets and stars to entire galaxies. These invisible forces influence major cosmic events and processes, including solar storms, the movement of high energy particles, and even galaxy formation. While small magnetic fields are often chaotic and turbulent, much larger magnetic structures…
Researchers at the University of Southern California have identified experimental compounds that could help reduce the brain inflammation associated with Alzheimer’s disease. The findings, published in the Nature journal npj Drug Discovery, focus on an enzyme called calcium-dependent phospholipase A2, or cPLA2, which appears to play an important role in…
Eating more legumes and soy foods may help lower the risk of developing high blood pressure, according to a large new analysis published in the open access journal BMJ Nutrition Prevention & Health. Researchers found that people who regularly consumed foods such as beans, lentils, chickpeas, tofu, edamame, and soy…
Researchers at the National Institutes of Health (NIH) have uncovered new details about how GLP-1 weight loss drugs such as semaglutide affect brain cells, revealing internal signaling processes that scientists have only begun to understand. The findings, based on experiments in mice, shed light on why these medications work differently…
Researchers at Flinders University have uncovered new details about one of the ancient fish species closely related to the first animals that eventually made the transition from water to land more than 380 million years ago. Using advanced neutron imaging technology, scientists examined the skull and braincase of Koharalepis jarviki,…
Amber from Myanmar’s Kachin region continues to reveal extraordinary glimpses into life during the age of dinosaurs. Preserved inside the 100 million-year-old resin are fossils from an ancient forest ecosystem that once supported a remarkable variety of creatures, including species never seen before. Now, researchers at Ludwig Maximilian University of…
For decades, beta blockers have been one of the routine drugs many patients receive after a heart attack. They are widely used for cardiac conditions and have long been considered a standard part of recovery after myocardial infarction. But a major 2025 clinical trial suggests that many people who have…
Generative AI is transforming the workplace faster than ever, but new research from the University of Vaasa suggests the biggest threat may not be AI itself — it’s falling behind in learning how to use it. Researcher Zhe Zhu found that employees who see tools like ChatGPT and Gemini as…
Every second, countless cells in the human body divide to create new cells. It is one of the most important processes in biology, and it depends on thousands of molecules working together with incredible precision. But sometimes the process breaks down in unexpected ways. Before a cell can divide into…
The Galápagos Islands off the coast of Ecuador are famous for animals found nowhere else on Earth, including giant tortoises and marine iguanas. Now, scientists have added another remarkable creature to that list: a tiny blue octopus newly identified in the deep waters surrounding the islands. The newly described species…
A simple beetroot juice routine may help explain one of the more surprising links in healthy aging: the connection between bacteria in the mouth and blood pressure. Research from the University of Exeter found that older adults who drank nitrate rich beetroot juice twice a day for two weeks saw…
Scientists have developed a new way to strengthen the cancer-fighting abilities of natural killer (NK) cells, a type of immune cell that serves as one of the body’s first defenses against disease. The strategy could help these cells overcome the protective barriers many tumors use to avoid being destroyed. Researchers…
Researchers at UT Southwestern Medical Center have identified a protein that acts as a key regulator of how the liver releases cholesterol carrying particles into the bloodstream.
