Scientists have developed a unique way to build electronic components so small they are made from chains of individual molecules—creating a toolbox to help build materials that could power the next generation of technology.

There is a silent killer lurking in the French Alps: ski lift cables. Over the last 60 years, the wires have accounted for almost 600 recorded landfowl deaths in the region. Black grouse (Lyrurus tetrix) account for ~70% ...

Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunts. Scientists from the GAIA Initiative have now published a machine ...

Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that same ball down to the size ...

A team of scientists has identified a new physical mechanism that could help explain one of the most persistent mysteries in science: why life consistently uses one "handed" version of its molecules and not the other. In ...

Additional product displays in supermarket aisles—so-called secondary placements—are intended to encourage impulse purchases. However, a new study by Mathias C. Streicher of the University of Innsbruck shows that excessive ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an international team led by a Penn ...

Research into human genomic diversity has a number of applications in biomedicine, evolution, and history. However, many populations have historically been underrepresented on the human genomic map. This is the case of Native ...

Amber from the Kachin region of Myanmar has preserved a wealth of fossils, offering insights into the diversity of the Cretaceous fauna of a 100-million-year-old forest ecosystem. The site continues to yield previously unknown ...

For more than 100,000 years, the Methana volcano in Greece appeared dormant. No lava, no explosions, no ash clouds. It appeared extinct, like many other volcanoes today. An international research team led by ETH Zurich has ...
