Wild chimpanzees alter the meaning of single calls when embedding them into diverse call combinations, mirroring linguistic operations in human language. Human language, however, allows an infinite generation of meaning by combining phonemes into words and words into sentences. This contrasts with the very few meaningful combinations reported in animals, leaving the mystery of human language evolution unresolved. Read more ›

Scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia's rainforests, highlighting the urgent need for conservation in the region, according to researchers.

Millions of kilometers of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a new study warns. The study estimated the scale of global river contamination from human antibiotics use. Researchers calculated that about 8,500 tons of antibiotics -- nearly one-third of what people consume annually -- end up in river systems around the world each year even after... Read more ›

Researchers have developed a new way to create hydrogels using ultrasound, eliminating the need for toxic chemical initiators. This breakthrough offers a faster, cleaner and more sustainable approach to hydrogel fabrication, and produces hydrogels that are stronger, more flexible and highly resistant to freezing and dehydration. The new method also promises to facilitate advances in tissue engineering, bioadhesives and 3D bioprinting. Read more ›

Researchers have developed a system, called ProxiCycle, that logs when a passing car comes too close to a cyclist (four feet or less). A small, inexpensive sensor plugs into bicycle handlebars and tracks the passes, sending them to the rider's phone. The team tested the system for two months with 15 cyclists in Seattle and found a significant correlation between the locations of close passes and other indicators of poor... Read more ›

A team partially replaced lithium in a lithium antimonide compound with the metal scandium. This creates specific gaps, so-called vacancies, in the crystal lattice of the conductor material. These gaps help the lithium ions to move more easily and faster, resulting in a new world record for ion conductivity. Read more ›

Researchers have developed two unique energy-efficient and cost-effective systems that use urea found in urine and wastewater to generate hydrogen. The unique systems reveal new pathways to economically generate 'green' hydrogen, a sustainable and renewable energy source, and the potential to remediate nitrogenous waste in aquatic environments.

A research team has achieved a significant breakthrough in developing broadly protective, live-attenuated influenza vaccines (LAIV). These innovative LAIV platforms offer potential to develop universal influenza vaccines that induce a more robust immune response against various virus subtypes, including both human and avian strains.

The Arctic landscape during the Cretaceous Period may have been dominated by the dinosaurs, but the rivers and streams held something more familiar. Alaska's fresh waters 73 million years ago were teeming with the ancient relatives of today's salmon, pike and other northern fish. A new article has named three new species of fish from that time period, including a salmonid, dubbed Sivulliusalmo alaskensis. Read more ›

Pregnant women with metabolic dysfunction-associated steatotic liver disease (MASLD) have an increased risk of giving birth prematurely and the risk increase cannot be explained by obesity, according to a new study. Read more ›

Metals and hormone-disrupting substances such as estrogens present a genuine risk to the sustainability of agriculture and water management in Europe. This research provides new insights into the distribution, availability, and risks associated with these pollutants, while also highlighting shortcomings in current regulations. Read more ›

In neurodegenerative diseases such as Alzheimer's or Parkinson's, proteins accumulate in the body's cells, fold incorrectly and clump together to form larger aggregates. Normally, cells are able to remove these aggregates themselves. However, if a certain enzyme is blocked, this clean-up process no longer works. The new findings provide a better understanding of the molecular basis of these processes. Read more ›

A research team used the German environmental satellite EnMAP (Environmental Mapping and Analysis Program) to simultaneously detect the two key air pollutants carbon dioxide (CO2) and nitrogen dioxide (NO2) in emission plumes from power plants -- with an unprecedented spatial resolution of just 30 meters. The newly developed method allows for tracking of industrial emissions from space with great precision and enables atmospheric processes to be analyzed in detail. Read more ›

The marine bacterium Alcanivorax borkumensis feeds on oil, multiplying rapidly in the wake of oil spills, and thereby accelerating the elimination of the pollution, in many cases. It does this by producing an 'organic dishwashing liquid' which it uses to attach itself to oil droplets. Researchers have now discovered the mechanism by which this 'organic dishwashing liquid' is synthesized. Read more ›
