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 / 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 / AI model 'hears' Bryde's whale calls in seismic data from South China Sea
Researchers have repurposed an AI model designed for visual identification tasks to detect Bryde's whale calls contained within seismic data collected in the South China Sea. The detection system precisely identified calls ...
Phys.org / 'Cold insurance' for crops: Researchers unlock 'on-demand' climate resilience
Rapidly intensifying global climate instability is causing increasingly erratic temperature fluctuations. When sudden cold snaps strike during a crop's critical flowering window, they trigger irreversible pollen abortion, ...
Phys.org / How anti-CRISPR proteins promote the spread of hospital-acquired infections
Researchers from Skoltech—a VEB.RF group institution—and their colleagues from the U.S. and China have explained how the antibiotic resistance gene established itself in the genome of the bacterium Klebsiella pneumoniae. ...
Phys.org / Algorithm visualizes how cells 'talk' to one another across tissue and time
People communicate with each other, sometimes face to face, sometimes with a text message or phone call. Cells also communicate with each other, sometimes by touching and sometimes by sending signals across space and time. ...
Phys.org / Dead organisms have a lasting ecological legacy, new research shows
Trees, grasses, corals, and oysters are foundational to the structure of an ecosystem while they are alive. But new research led by the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University ...
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 / 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 / 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 / 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 / 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 ...
