Every society has some degree of wealth inequality—over history, across continents, there always seem to be some people who have more than others. But the amount of inequality differs—in some civilizations, a few powerful ...
Insects that fall from the surrounding forest provide seasonal food for fish in streams. Researchers at Kobe University and The University of Tokyo have shown that the lengthening of this period has a profound effect on food ...
Asked in 2003, the UK's astronomer royal, Martin Rees, gave our present society 50/50 odds of lasting until the end of the century. It's fair to say the odds haven't improved in the years since he made this call. The planet ...
Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, ...
The media has been rife with stories about democracy in decline: the recent coup in Myanmar, the ascent of strongman Narendra Modi in India, and of course ex-President Trump's attempts to overturn the U.S. presidential election—all ...
A refractive index of zero induces a wave vector with zero amplitude and undefined direction. Therefore, light propagating inside a zero-index medium does not accumulate any spatial phase advance, resulting in perfect spatial ...
Until recently, scientists believed that only very massive nuclei could have excited zero-spin states of increased stability with a significantly deformed shape. Meanwhile, an international team of researchers from Romania, ...
Many animal groups decide where to go by a process similar to voting, allowing not only alphas to decide where the group goes next but giving equal say to all group members. But, for many species that live in stable groups—such ...
The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its eyes to the skies, examining phenomena ranging from supernovae to magnetic ...
All good things must come to an end. Whether societies are ruled by ruthless dictators or more well-meaning representatives, they fall apart in time, with different degrees of severity. In a new paper, anthropologists examined ...
