Phys.org / Over 70% of global ecosystems remain unsampled for critical underground fungi
Underground, intricate networks of soil fungi underpin the functioning of terrestrial ecosystems. Yet despite their global importance, only 30% of global ecosystems have been sampled for these fungal partners. Arbuscular ...
Phys.org / Political polarization can spur CO₂ emissions and stymie climate action
In recent years, studies and media reports have blamed growing partisan hostility in the U.S. for shattered marriages, broken families, ruined holiday dinners, and increased stress. New CU Boulder research suggests it may ...
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 / 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 / A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
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 ...
