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 / 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 / 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 / Neanderthal males, human females? How ancient attraction shaped the human genome
The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia. Genomic research by members of Sarah Tishkoff's lab at the University of Pennsylvania are revisiting ...
Phys.org / Turning over a new leaf in analyses of natural products
Scientists have developed a new way to help understand what happens in the body when people consume a plant product and the many chemicals it contains. The Journal of Natural Products published the method to quickly analyze ...
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 / Tackling the global tuberculosis crisis: An emerging class of antibiotics offers hope
Researchers from the University of Sydney and the Centenary Institute have discovered how a promising class of experimental antibiotics disrupts the bacterium that causes tuberculosis (TB), paving the way for urgently needed ...
Phys.org / Laser technique can quickly check mRNA packaging in lipid nanoparticles
Messenger RNA (mRNA) technology is transforming medicine by providing our cells with genetic instructions to produce proteins that help the immune system prevent or fight a wide range of diseases, including cancer and other ...
