Researchers have succeeded in combining two major research fields in photonics by creating a nano-object with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices.

Since their invention in the 1920s, jungle gyms and monkey bars have become both fixtures of playgrounds and symbols of childhood injury that anxious caretakers want removed. Anthropologists mark 100 years of the iconic playground equipment by arguing that risky play exercises a biological need passed on from apes and early humans for children to independently test and expand their physical and cognitive abilities in a context in which injury...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged antimatter positron. It is naturally very short-lived, but researchers have now successfully cooled and slowed down samples of positronium using carefully tuned lasers. They hope this research will help others explore exotic forms of matter, and that such research might unlock... Read more ›

Neuroscientists have revealed how sensory input is transformed into motor action across multiple brain regions in mice. The research shows that decision-making is a global process across the brain that is coordinated by learning. The findings could aid artificial intelligence research by providing insights into how to design more distributed neural networks. Read more ›

Analysis of air samples taken at altitudes of up to 3,000 meters above Japan has revealed the presence of a vast range of viable bacteria and fungi transported by air masses originating more than 2,000 kilometers away, in regions enriched with fertilizers and pesticides. The study reveals a new way in which human, animal and plant pathogens may travel to distant geographical regions. Read more ›

Astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained in July and August 2023. They show giant, hot bubbles of gas, 75 times the size of the Sun, appearing on the surface and sinking back into the star's interior faster than expected. Read more ›

Water polluted with heavy metals can pose a threat when consumed by humans and aquatic life. Sugar-derived polymers from plants remove these metals but often require other substances to adjust their stability or solubility in water. Now, researchers report a sugar-like polymer that traps heavy metals within insoluble clumps for easy removal. In proof-of-concept tests, the polymer removed ionic cadmium and lead from river water spiked with these persistent contaminants. Read more ›

For the design of reliable power grounding systems for critical electrical infrastructure, soil resistivity investigation is crucial. However, soil resistivity depends on various geotechnical properties, necessitating the need for robust assessment methods. In a new study, researchers conducted a comprehensive investigation into the behavior and relationships between soil resistivity and key geotechnical parameters and developed a predictive model based on their findings. This model can lead to cost-effecti Read more ›

A computer algorithm can efficiently find genetic mutations that work together to drive cancer as well as other important genetic clues that researchers might someday use to develop new treatments for a variety of cancers. Researchers used a novel network computer model to find co-occurring mutations as well as other similarities among DNA sequence elements across several types of cancer. The model allows for easier searches for patterns in huge... Read more ›

Newborns who had an atypical pattern of metabolites were more than 14 times as likely to die of sudden infant death syndrome (SIDS), compared to infants who had more typical metabolic patterns, according to a new study. Metabolites are molecules produced by the body's various chemical reactions. Researchers found that infants who died of SIDS had a specific pattern of metabolites compared to infants who lived to their first year.... Read more ›

Summer storms are generally more frequent, intense and concentrated over cities than over rural areas, according to new, detailed observations of eight cities and their surroundings. The results could change how city planners prepare for floods in their cities, especially as urban areas expand and as climate change alters global weather patterns. Read more ›
