Direct reciprocity facilitates cooperation in repeated social interactions. Traditional models suggest that individuals learn to adopt conditionally cooperative strategies if they have multiple encounters with their partner. ...

Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach by researchers involving the Institute of Science ...

An innovative synthesis strategy has opened the way to 2D/3D fused frameworks using inexpensive quinolines as feedstock, report scientists from Tokyo Tech. By leveraging a light-sensitive borate intermediate, the scientists ...

A discovery by researchers at the University of Houston has revealed a massive energy imbalance on Saturn, shedding new light on planetary science and evolution and challenging existing climate models for the solar system's ...

The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies ...

Europe experienced its coldest winter in 600 years during 1739–1740, ~4 °C cooler than the present average, also coinciding with negative temperature anomalies across North America and Eurasia. Indeed, for northern midlatitudes ...

Astronomers have performed a comprehensive chemical study of a Galactic globular cluster known as Terzan 6. Results of the study, presented in a research paper published June 11 on the pre-print server arXiv, could advance ...

Hundreds of thousands more breeding pairs of seabirds could return to remote island archipelagos if invasive rats were removed and native vegetation restored, a new paper finds.

While investigating how string theory can be used to explain certain physical phenomena, scientists at the Indian Institute of Science (IISc) have stumbled upon on a new series representation for the irrational number π. ...

In late 2019, the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including ...

Remember how difficult it was to find one Higgs boson? Try finding two at the same place at the same time. Known as di-Higgs production, this fascinating process can tell scientists about the Higgs boson self-interaction.

Details of an ancient cousin of modern-day mammals are being revealed for the first time. Hi-tech scanning of an ancient fossil, which was captured in sandstone around 252–254 million years ago, is giving experts valuable ...
