How do cells know when to activate or slow down their activity? A team from the University of Geneva (UNIGE) provides new insights by studying TORC2, an essential but still poorly understood protein complex. Using ultra-high-resolution ...

Eastern Africa's Turkana Rift is both a hotbed for fossil discoveries of our earliest ancestors and a literal hotbed of volcanic activity caused by shifting tectonic plates. Now researchers have found that Earth's underlying ...

New research shows that variation in mating behaviors, parental care and differences in ornamentation of the sexes in bird species is driven by demographics rather than vice versa. An international team of researchers from ...

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 ...

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 ...

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 ...

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 ...

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 ...

Cooperation is a pillar of human society, promoting an exchange of skills and knowledge between different individuals and social groups. Humans typically do not only cooperate with their own family, friends and members of ...

Mud-rich coastlines could face a greater tsunami risk, at least that may have been the case for the 2011 Tōhoku-oki tsunami that killed more than 19,000 people and led to the Fukushima Daiichi nuclear disaster. According ...
