Alzheimer’s disease is often described in numbers, with millions of people affected, cases rising quickly, and costs reaching into the trillions. For families, however, the experience is deeply personal. “It’s a slow bereavement,” says Cold Spring Harbor Laboratory Professor Nicholas Tonks, whose mother lived with Alzheimer’s. “You lose the person…
A large study published in The BMJ suggests that aerobic activities such as walking, cycling, and swimming are the most effective exercises for people with knee osteoarthritis. These activities were found to provide the greatest improvements in pain, physical function, walking ability, and overall quality of life. Researchers note that…
Psychologists have long debated whether the human mind can be explained by a single, unified theory or if different functions such as attention and memory must be studied separately. Now, artificial intelligence (AI) is entering that debate, offering a new way to explore how the mind works. In July 2025,…
An international team of researchers, including scientists from Paderborn University, has reached an important milestone on the path toward a quantum internet. For the first time, they successfully teleported the polarization state of a single photon from one quantum dot to another that was physically separated. In simple terms, this…
Smell shapes how we experience the world every day. It helps us detect hazards, adds depth to flavor, and connects strongly to memory and emotion. Despite its importance, scientists have struggled to fully understand how this sense works at a biological level. “Olfaction is super-mysterious,” said Sandeep (Robert) Datta, professor…
Cytotoxic T lymphocytes act as the immune system’s specialized “killer” cells, seeking out and eliminating infected or cancerous cells with remarkable precision. Their effectiveness depends on a tightly controlled contact point called the “immune synapse,” where they release toxic molecules that destroy the target while leaving surrounding healthy cells unharmed.…
Scientists have, for the first time, clearly captured a subduction zone in the act of breaking apart. These zones form where one tectonic plate sinks beneath another, and they are responsible for some of the most powerful geological events on Earth. The new findings, published in Science Advances, offer a…
Archaeologists have uncovered six previously unknown Bronze Age mining sites in Extremadura in southwestern Spain. The discoveries were made during a February survey led by researchers from the Maritime Encounters program at the University of Gothenburg in Sweden. These sites could help answer a long-standing question about where the metal…
Modern cells are highly intricate systems. They contain internal scaffolding, tightly controlled chemical processes, and genetic instructions that guide nearly everything they do. This complexity allows them to survive in diverse environments and compete based on their fitness. In contrast, the earliest cell-like structures were extremely simple. These primitive compartments…
A newly identified species of ancient snake, Vasuki indicus, may rank among the largest snakes to ever exist. The massive reptile lived around 47 million years ago in what is now Gujarat, India, according to research published in Scientific Reports. Scientists estimate it reached an extraordinary length of about 11…
Scientists have known for nearly a century that the universe is expanding, but the exact rate of that expansion is still uncertain. This ongoing debate has even raised questions about the standard model of cosmology. Now, researchers from the Technical University of Munich (TUM), Ludwig Maximilians University (LMU), and the…
Defining where the Milky Way ends has always been challenging because its disk does not stop abruptly — it gradually fades into space. Now, for the first time, an international team of astronomers has pinpointed the boundary of the Galaxy’s star-forming disk by examining the ages of stars. Their findings…
A medication that has been around for decades and used to treat several conditions, including a chronic parasitic infection, is now emerging as a potential option for patients with a different and far rarer disease. Early findings suggest the drug could help people with Bachmann-Bupp syndrome (BABS), a life-threatening genetic…
A new study from MIT indicates that a cancer-causing chemical found in some medications and in drinking water contaminated by industrial activity may pose a much greater risk to children than to adults. In experiments with mice, researchers discovered that young animals exposed to water containing this compound, called NDMA,…
NASA’s Curiosity rover has identified a wide range of organic molecules on Mars, including compounds that scientists consider key ingredients for the origin of life on Earth. The discovery comes from a chemical experiment carried out on another planet for the first time. Results show that the Martian surface is…
One of the defining breakthroughs that set quantum physics apart from classical physics was the realization that matter behaves very differently at extremely small scales. Among the most important discoveries was wave-particle duality, the idea that particles can also act like waves. This concept became widely known through the double-slit…
Researchers at MIT have identified an unexpected effect in optical physics that could lead to a faster and more detailed way to image living tissue. Under specific conditions, what normally looks like a scattered and disordered laser signal can reorganize itself into a narrow, highly focused “pencil beam.” With this…
Why do some dreams feel vivid and lifelike, while others are confusing or hard to remember? New research from the IMT School for Advanced Studies Lucca suggests that the answer lies in a mix of personal traits and shared life experiences, both of which influence what we see and feel…
Scientists are still working to understand why Neanderthals went extinct while Homo sapiens established a lasting presence in Europe. The answer is not simple. It likely involves several overlapping factors, but a new study using techniques inspired by digital ecology is offering a clearer picture. The research was led by…
Scientists have achieved a significant breakthrough in their effort to understand dark energy by completing observations for the full target area of the Dark Energy Spectroscopic Instrument (DESI)’s 3D map of the universe. The project wrapped up ahead of schedule and delivered far more data than originally anticipated. This map…
Researchers in Brazil have found that a simple vitamin D supplement may help chemotherapy work better in women with breast cancer. The study, carried out at the Botucatu School of Medicine at São Paulo State University (FMB-UNESP), suggests that low doses of the vitamin could improve treatment outcomes and potentially…
In quantum materials, electronic order rarely forms in a smooth, uniform way. Instead, it often appears as complex patterns that vary from one region to another. One well-known example is the charge density wave (CDW), a state in which electrons organize into repeating patterns at low temperatures. While CDWs have…
Researchers at the University of Utah have identified an enzyme called PapB that can reshape therapeutic peptides, a class of protein-like drugs, by linking their ends together into tight rings. This process, known as macrocyclization, creates compact structures that can improve how these medicines perform in the body. The discovery…
Between 750 and 900 CE, the Maya lowlands in Central America went through a dramatic drop in population and political power. For years, researchers linked this decline to repeated periods of severe drought. That explanation has long dominated scientific thinking. But new findings based on sediment records stretching back 3,300…
A strange object known as the “golden orb” puzzled scientists and captured public attention after it was collected during a 2023 NOAA expedition. More than two years later, researchers have finally identified what it is. The unusual golden mass, discovered at a depth of 3,250 meters (over 2 miles) in…
Mammals once shared the planet with dinosaurs until a catastrophic event 66 million years ago wiped out about 75% of all life on Earth. Even so, some species managed to survive. Among them were small, rodent-like mammals belonging to the genus Cimolodon. These animals were part of the multituberculates, a…
Stress that people turn inward may be quietly increasing the risk of memory loss in older Chinese Americans, according to new research from Rutgers Health. The study, published in The Journal of Prevention of Alzheimer’s Disease, was conducted by researchers at the Rutgers Institute for Health, Health Care Policy and…
Cryopreservation, the process of preserving biological tissue by cooling it to extremely low temperatures, often sounds like something out of science fiction. In reality, scientists have been studying and refining this technique for nearly a century. Progress remained slow for decades, but that began to change in 2023, when researchers…
Modern cosmology is often associated with massive observatories, advanced instruments, and large international collaborations backed by significant funding. However, meaningful progress does not always require such scale. Even in the complex search for dark matter, smaller teams with creative approaches and institutional support can still make important contributions. A recent…
For the first time, researchers have directly visualized the quantum behavior that drives superconductivity, a state in which paired electrons allow electricity to flow with zero resistance at very low temperatures. But what they observed came as a surprise. In a study published April 15 in Physical Review Letters, the…
