Phys.org / Acoustic environment may explain why some bird songs outlast others
From melodic morning choruses to territorial songs that echo through forests and grasslands, birds rely on vocalizations to communicate, attract mates and defend valuable habitat. For songbirds, these vocal displays are not ...
Phys.org / Open-source FLIM Playground could speed reproducible analysis of complex cell images
Modern fluorescence microscopy can generate images of living cells as stunning to look at as they are informative to study. For techniques like fluorescence lifetime imaging microscopy (FLIM), those images provide a window ...
Phys.org / How Argonaute, a key protein for RNA therapeutics, becomes activated
RNA therapeutics have emerged as one of the most promising new classes of medicines. Eight small interfering RNA (siRNA) drugs have already been approved worldwide for the treatment of genetic diseases, yet scientists have ...
Phys.org / 'Cool Routes' finds cooler walking paths with hourly forecasts and street-level shade data
The Arizona sunshine hits like a blowtorch. The pavement radiates heat like a stove burner. To make hot-weather walking less of an ordeal, Arizona State University researchers have created a web-based app that finds the coolest, ...
Phys.org / Maya altar and offerings at abandoned Belize sites highlight enduring ritual activities
Archaeologists excavating Maya sites at Kaxil Uinik and Ayiin Winik in Belize have discovered the first reported Late Postclassic altar in the region, along with additional evidence that Postclassic Maya people continued ...
Phys.org / Dino-killing asteroid may have fueled underground life for 8 million years
The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected.
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.
