Phys.org / Satellite data reveal Southern Ocean vertical currents diving 3,000 feet below surface
Ocean currents are not just horizontal motions that flow from side to side. There are also vertical currents that act like deep-sea elevators, pushing heat and carbon down into the deep, while bringing up vital nutrients ...
Phys.org / Possible dark matter-deficient twins discovered in the Fornax Cluster
Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC 240, on the outskirts of ...
Phys.org / Quantum memory surpasses classical limits for storing unknown quantum operations
Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing tasks. Yet these promising memories could also complete operations ...
Phys.org / Oldest Maya Long Count calendar date may reveal how royalty turned time into power
Archaeologists working at the ancient Maya site of El Palmar in Campeche, Mexico, have discovered what may be the earliest known Long Count calendar date in the Maya lowlands. It is carved into a stone monument and is interpreted ...
Phys.org / Iberian DNA remained largely unchanged for six centuries before Roman influence, study finds
A study led by a UAB research team of Biological Anthropology has analyzed the genome of 54 newborns with the aim of tracking the genetic history of their culture since it developed in the Early Iron Age until the start of ...
Phys.org / A lack of sex held back life's diversity for millions of years, fossil study finds
The way that Earth's first animals reproduced held back life's diversity for millions of years, until stress and competition led to the development of sexual reproduction, which in turn accelerated the pace of evolution.
Phys.org / Chasing the ghost dog of the Amazon: New insights into a mythical canid
For decades, the short-eared dog (Atelocynus microtis) has been considered one of the least-known carnivores in Latin America, and potentially one of the least-known canids in the world. Because of its highly secretive nature, ...
Phys.org / Silent volcanic gas buildup revealed six months before La Palma eruption
Researchers at Geosciences Barcelona (GEO3BCN-CSIC) have developed a novel way to monitor the silent accumulation of volcanic gases beneath Earth's surface using seismic ambient noise. The results could significantly improve ...
Phys.org / Physicists observe synchronized quantum dance of excitons and phonons
An international team of researchers has reported a major advance in understanding quantum dynamics in semiconductor materials. They directly observed how excitons and phonons evolve together in perovskite nanocrystals, revealing ...
Phys.org / Freshwater boundary breach deepens as climate and land use amplify extremes
Human activities have significantly altered the freshwater cycle, threatening its ability to support vital climatic and ecological Earth system processes. A new study led by researchers at the University of Eastern Finland ...
Phys.org / Brain removal in Iron Age Scotland burial reveals far-reaching family ties
It is difficult to identify funerary practices in Iron Age (c. 800 BC–AD 43) Britain, as human remains rarely survive. However, evidence is particularly prominent in north-west Scotland, because environmental conditions support ...
Phys.org / New 3D microscope technology captures high-resolution tissue images at a fraction of the cost
A team led by Raju Tomer, professor of biological sciences at Columbia University, has created a new design for microscopes and microscope lenses that could push 3D tissue imaging beyond state-of-the-art systems while drastically ...
