Phys.org / Rydberg atoms detect clear signals from a handheld radio
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah ...
Phys.org / Single-celled organism becomes multicellular via three different pathways
Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger multicellular organism. A new ...
Phys.org / Energy loss triggers quantum thermal Hall-like effect at macroscopic scale
In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy ...
Phys.org / Sea urchin spines inspire self-powered underwater sensors
Nature does it again! The natural world has a knack for giving us the blueprints for some useful technologies, and the humble sea urchin is the latest contributor. Scientists have designed a new class of smart sensors by ...
Phys.org / Hotspots of accelerated North American bird decline linked to agricultural activity
Though previous research has shown that bird populations are declining across North America, a new study is the first to show that the pace of loss has picked up speed since the mid-1980s in three regions: the Midwest, California ...
Phys.org / Russian astronomers observe the eruptive behavior of a young star
Russian astronomers from Moscow State University have performed photometric, polarimetric, and spectroscopic observations of a young star designated IRAS 21204+4913. Results of the new observations, which were published February ...
Phys.org / From the Late Bronze Age to today, the Old Irish Goat carries 3,000 years of Irish history
New research has revealed that the Old Irish Goat shares a 3,000-year genetic link with goats living in Ireland during the Late Bronze Age. The findings suggest that the rare indigenous breed represents a continuous Irish ...
Phys.org / Matching vibrations is all it takes to shut down superconductivity in a nearby crystal
The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you'll find quantum fluctuations. In thin, two-dimensional materials, these include random ...
Phys.org / Romance and sexual intimacy don't diminish with age, study suggests
A study by the University of New Hampshire challenges common assumptions about aging and intimacy, revealing that many single adults aged 60 to 83 continue to prioritize sexual activity in their romantic relationships—underscoring ...
Phys.org / A cosmic explosion with the force of a billion suns went unseen—until we caught its echo
Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front plows into its surrounding ...
Phys.org / Green turtle nests may bury 'plastic rocks' and endanger the species
Even the most remote regions of the globe are not free from plastic pollution. In a study published in Marine Pollution Bulletin, researchers from São Paulo State University (UNESP) in Brazil have detected plastic rocks ...
Phys.org / Study of 40,000 cases links Somalia migration mainly to water scarcity
A study published in Nature Food by researchers from the Politecnico di Milano and the University of California at Berkeley provides forward-thinking answers to the debate on the role of environmental stresses on migration ...
