When shown a mirror, these small reef fish did more than appear to recognize ...

A hidden pigment helps ocean algae harness sunlight without getting burned—and it may hold clues for better solar tech. Too much sunlight can spoil a beach day, and it can also damage photosynthesis, the process plants and algae use to turn light into energy. Excessive exposure can overwhelm this sy...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in single particles. In condensed matter physics, some of the most surprising behavior appears only when many quantum particles interact as a group. Individual quantum spins can beha...

A scientist has explained why robots still struggle to pick tomatoes. Labor shortages in agriculture are driving growing interest in robotic systems that can automate harvesting. Yet some crops remain especially challenging for machines. Tomatoes, for example, grow in clusters, meaning robots must i...

Human clinical trials reveal that black cumin has anti-obesity and heart-protective effects. Nigella sativa (black cumin) is best known as a flavorful spice used in dishes like korma and paneer, but it also has a long history in traditional medicine across South Asia, the Middle East, and North Afri...

Researchers in Japan found that although the Alzheimer’s drug lecanemab successfully removes amyloid plaques from the brain, it does not restore the brain’s waste-clearing system within the first few months of treatment. The study suggests that by the time symptoms appear, damage to nerve cells and ...

In Tokyo, scientists have found that the longer you commute and the smaller your home, the more likely you are to struggle with insomnia. The study highlights a powerful urban trade-off: the convenience of city living versus the deep rest our bodies need. Smarter housing and commuting solutions coul...

A powerful new molecule, GAI-17, has shown striking results in reversing brain damage caused by stroke—even when given up to six hours after the event. Developed by researchers in Japan, the drug blocks a protein that triggers neuron death, sharply reducing paralysis and brain cell loss in mice. Eve...

Morning light conditions before waking up can impact how restful your sleep feels. Sleep is an essential part of daily life, yet modern lifestyles and constant exposure to technology have led to reduced sleep duration and increased fatigue. Despite its importance, the bedroom environment, including ...

A team of Japanese researchers has harnessed the power of AI to uncover hidden structures in our galaxy. Using deep learning models trained on space telescope data, they identified bubble-like formations linked to star births and supernova explosions. These so-called Spitzer bubbles hold key insight...

Physicists in Japan have developed streamlined formulas to measure quantum entanglement, revealing surprising quantum interactions in nanoscale materials. Their research offers fresh insights into strongly correlated electron systems and potential applications in quantum technology. Einstein’s “Spoo...

Anemonefish, famously known as clownfish, have long been admired for their vibrant colors and their fascinating relationship with sea anemones. While it’s well-known that these fish protect their hosts from predators, new research reveals that they also feed them — offering food they can&#8217...

In the frozen world of Antarctica, one tiny insect has mastered the art of survival. The Antarctic midge, the only insect native to the continent, endures extreme conditions using a fascinating combination of dormancy strategies. Researchers have discovered that it switches between two distinct form...

Scientists clarify key indicator of chemical activity: the correlation between liquid properties and the generation of active bubbles explained. Active bubbles, also known as acoustic bubbles, show promise in applications ranging from water purification to medicine. These microbubbles are generated ...

Model mice treated with extracts and powders exhibit restored cognitive and motor functions. Efforts to develop a breakthrough dementia drug are gaining attention, yet traditional medicinal products may provide valuable insights for preventive care. A research group led by Specially Appointed Profes...

An analysis of factors influencing population changes in relation to city size. Aging populations and declining demographics are growing concerns worldwide, but the issue has intensified significantly in Japan. An alarming 36.21 million people, or 28.9% of the population, are aged 65 and over. Addit...

Scientists have made significant strides in visualizing and manipulating tiny magnetic regions in quantum materials using light. This breakthrough not only deepens understanding of magnetic materials at the quantum level but also advances the development of next-generation electronics and memory dev...

Research indicates that stromatoporoids, ancient reef-builders, withstood the Late Devonian extinction and prospered into the Carboniferous Period. Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet — for a while, at least. S...

Cleaner wrasse check their body size before fights due to having their own mental representation. Researchers at Osaka Metropolitan University discovered that bluestreak cleaner wrasse use mirrors to assess their size relative to potential competitors, marking the first evidence of private self-awar...

Ecklonia cava, a type of brown algae seaweed, has demonstrated potential in protecting against neurodegenerative diseases. Parkinson’s disease is a neurodegenerative disorder characterized by the degeneration of dopamine-producing neurons, which are crucial for motor control and cognitive func...

Certain nucleosides impede the replication of tumor cells as a step toward preventing cancer. When individuals consume food, they also ingest nucleic acids found in all living organisms.
