A meta-study of over 1.3 million participants found that moderate-intensity physical activity decreases all-cause mortality by 10%, while vigorous-intensity aerobic activity or sports reduces it by 22%. Engaging in any physical activity, including daily activities, can still provide a survival benefit.
Researchers at the University of Vienna aim to measure general relativistic time on a quantum scale by exploiting quantum interference and complementarity. They consider a single clock in a superposition of two locations, one closer and one further away from Earth, where gravity's effects are different.
A new scheme, 'coherent photon conversion', offers a method for coherent conversion between different photon states using a strong laser field. This approach promises to solve open challenges in optical quantum computation and lead to the development of a nonlinear optical quantum computer.
Researchers develop a method using flashes of light to observe quantum features of large objects with unprecedented resolution. By analyzing the dynamics of such behavior, pulsed quantum optomechanics provides a path for investigating whether macroscopic mechanical objects can be used in future quantum technologies.
Researchers have detected stellar oscillations in a hotter star, revealing insights into its internal structure and composition. The discovery was made possible by the Kepler space telescope and provides new information on the processes that govern stellar behavior.
A research team led by Franz Klein has analyzed the mechanism of meiosis at high resolution, finding that DNA-break machines are tightly associated with chromosomal axis regions. This discovery sheds light on how breaks on chromosomes impede other breaks in their vicinity and how shape changes influence the function of these machines.
Tiny particles in liquids form cluster crystals that exhibit regular structures and flow like strings under mechanical strain, altering viscosity. The behavior is the same for all types of cluster crystals, with critical strains predicted using a simple theoretical model.
Researchers at the University of Vienna have developed a method called "passive sampling" to measure the affinity of contaminants to carbon nanotubes. This method provides reliable results for realistic applications and can remove pollutants from contaminated water, making it a promising technology for water filtration.
Mutations in Timothy syndrome can cause severe cardiovascular disorders by disturbing calcium homeostasis. The current research focuses on the structure of L-calcium channels and reveals a highly conserved motif called G/A/G/A, essential for sealing the closed channel pore.
Marine biologists have identified a 500-million-year-old symbiotic relationship between catenulid flatworms, like Paracatenula, and Alpha-Proteobacteria. The unique Riegeria symbionts have been found to account for up to 50% of the worm's tissue and are believed to be responsible for its nutrition.
Researchers led by Anton Zeilinger found that quantum mechanical measurements cannot be interpreted classically even when no entanglement is involved. This challenges the idea of 'spooky action at a distance', sparking debate about the limits of classical physics.
Researchers investigated problem-solving abilities and innovative capacities of kea and New Caledonian crow. The studies revealed that both species employ various tools to achieve food rewards, with the kea mastering compact object tools and the crow using elongated objects like sticks to probe for grubs.
Researchers at the University of Vienna and Austrian Academy of Sciences have successfully simulated a frustrated quantum system using entangled photons. The experiment offers enormous potential for future quantum simulators to study complex quantum phenomena.
Researchers have isolated a new species of ammonia oxidizing archaeon from soil, named Nitrososphaera viennensis. The discovery has significant implications for agriculture, as ammonia oxidation affects nitrogen availability for plants and groundwater nitrate levels.
Researchers successfully demonstrated quantum behavior in molecules with over 400 atoms, resolving a key aspect of 'Schroedinger's cat.' The experiment used tailor-made organic molecules that can exist in a superposition of clearly distinguishable positions.
