Phys.org / Fossil amber reveals the secret lives of Cretaceous ants
Tiny insects trapped in amber could tell us a great deal about their roles in past ecosystems: pollinators, parasites, predators, and prey. But how many of the insects preserved alongside each other reflect interactions during ...
Phys.org / A new, useful absorption limit for ultra-thin films
The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought their efficacy is limited to absorbing only half of the incidental light at best. A research group ...
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 / 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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / Exceptionally preserved 551-million-year-old site suggests Avalon biota lasted longer
Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, ...
Phys.org / Using high-energy sparks to degrade pollutants without generating waste
A study published in the Chemical Engineering Journal proposes a new approach to environmental remediation of pharmaceutical pollutants in water flows. This approach is based on a phenomenon known as "sparks," which refers ...
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 ...
