Phys.org / Meta-analysis challenges the link between economic inequality and mental health
Does living in an unequal society make people unhappy? Not necessarily, reveals the largest study ever conducted on the subject. Nicolas Sommet, a social psychologist and research manager at the LIVES Centre at the University ...
Phys.org / How a soft coral moves its tentacles in perfect synchronization without a brain
A joint study by Tel Aviv University and the University of Haifa set out to solve a scientific mystery: how a soft coral is able to perform the rhythmic, pulsating movements of its tentacles without a central nervous system. ...
Phys.org / Possible Black Death mass grave discovered near Erfurt, Germany
An interdisciplinary research team from Leipzig has discovered strong evidence of a Black Death mass grave near the deserted medieval village of Neuses, outside Erfurt (Germany). It represents the first systematically identified ...
Phys.org / Webb delivers unprecedented look into heart of Circinus galaxy
The Circinus galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black ...
Phys.org / New global standard set for testing graphene's single-atom thickness
Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The University of Manchester has led the world's largest study to set a new global benchmark for testing graphene's ...
Phys.org / Cyanobacteria can utilize toxic guanidine as a nitrogen source
Guanidine is an organic compound primarily used as a denaturing reagent to disrupt the structures of proteins and nucleic acids. Together with partner institutions, scientists at the Helmholtz Centre for Environmental Research ...
Phys.org / Phages and bacteria accumulate distinctive mutations aboard the International Space Station
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless "microgravity" conditions aboard the International Space Station, but the dynamics of virus-bacteria ...
Phys.org / Quantum-dot device can generate multiple frequency-entangled photons
Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path to more powerful quantum ...
Phys.org / Massive supernova from Wolf-Rayet star could be precursor to black hole binary
What we know of the birth of a black hole has traditionally aligned with our perception of black holes themselves: dark, mysterious, and eerily quiet, despite their mass and influence. Stellar-mass black holes are born from ...
Phys.org / How the Tibetan Plateau-Himalayan uplift shaped Asian summer monsoons
Research from Monash University reveals the climate history behind Asia's summer monsoon—Earth's most influential climate system. In a new study published in npj Climate and Atmospheric Science, an international team of ...
Phys.org / Organisms in the Atacama Desert soil are remarkably diverse, study shows
A new study shows that resilient and remarkably diverse populations of organisms can persist in the soil despite harsh and extremely dry conditions. An international team led by researchers from the University of Cologne, ...
Phys.org / New tool lets anyone audit a country's methane claims
For years, countries have told the United Nations how much methane they emit using a kind of bottom-up bookkeeping: Count the cows and oil barrels, estimate the volume of trash, and multiply by standard emission factors.
